Five fundamentals questions with answers
Cover the key. Write the first action. Then open the rationale and name why the other choices fail.
Question 1
Calcium is stored and released in skeletal muscle by the
A. sarcolemma
B. sarcoplasmic reticulum
C. T-tubules
D. caveoli
Show answer and rationale
Correct answer: B — sarcoplasmic reticulum
The sarcoplasmic reticulum (SR), a specialized endoplasmic reticulum in skeletal muscle, stores and releases calcium to trigger contraction. Surrounding myofibrils, it sequesters calcium via calsequestrin, maintaining low cytosolic levels (10^-7 M) at rest. Upon T-tubule-transmitted action potentials, SR terminal cisternae release calcium (rising to 10^-5 M) through ryanodine receptors, binding troponin to initiate actin-myosin interaction. The sarcolemma conducts the initial depolarization, not storage. T-tubules relay signals inward but lack storage capacity. Caveoli (likely a typo for caveolae) are membrane invaginations, irrelevant here. Myofilaments use calcium but don't store it. The SR's role, detailed in muscle physiology, is critical: its ATPase pumps reuptake calcium post-contraction, relaxing the fiber. Electron microscopy reveals its extensive network, ensuring rapid, uniform calcium spread, distinguishing it from signal-conducting or contractile structures in excitation-contraction coupling.
Question 2
A nurse obtained a client's pulse and found the rate to be above normal. The nurse documents this finding as:
A. Tachypnea
B. Hyper pyrexia
C. Arrythmia
D. Tachycardia
Show answer and rationale
Correct answer: D — Tachycardia
Pulse rate assessment involves measuring the heart rate, typically at the radial artery, and noting whether it exceeds the normal range of 60-100 beats per minute in adults. When the pulse rate is above normal, it indicates an accelerated heart rate, which is medically termed tachycardia (D), defined as a heart rate exceeding 100 beats per minute at rest. Tachypnea (A) refers to rapid breathing, not heart rate, and is unrelated to pulse findings. Hyperpyrexia (B) denotes an extremely high fever (typically above 41.5°C), which could cause a rapid pulse but is a temperature-related term, not a direct pulse descriptor. Arrhythmia (C) indicates an irregular heart rhythm, which may or may not involve an elevated rate; however, the question specifies only an above-normal rate without mentioning irregularity. Thus, tachycardia is the precise term for documenting a pulse rate above normal, making D the correct answer. This distinction is critical in nursing to ensure accurate communication of clinical findings.
Question 3
Following the death of a child, one of the parents begins to falsely accuse other members of the family of blaming the child's death on the parent. This leads to family members avoiding the mentioned parent for fear of the false accusation. The parent takes this as proof that the family truly believes the accusation. This sets up a destructive cycle of family dysfunction. Which nursing diagnosis is most appropriate for this family?
A. Impaired family processes related to impaired adjustment
B. Impaired adjustment related to loneliness
C. Loneliness related to fear
D. Dysfunctional grieving related to loss of relationships
Show answer and rationale
Correct answer: D — Dysfunctional grieving related to loss of relationships
The correct answer is D: Dysfunctional grieving related to loss of relationships. This nursing diagnosis is most appropriate because the parent's behavior following the child's death is indicative of dysfunctional grieving, as they are falsely accusing family members and experiencing a breakdown in relationships. This behavior is a maladaptive way of coping with the loss, leading to further dysfunction within the family.
A: Impaired family processes related to impaired adjustment does not fully capture the specific issue of dysfunctional grieving and loss of relationships.
B: Impaired adjustment related to loneliness focuses more on the individual's emotional state rather than the family dynamics and dysfunction.
C: Loneliness related to fear does not address the core issue of dysfunctional grieving and the breakdown in family relationships.
In summary, the parent's behavior and the resulting family dysfunction point towards dysfunctional grieving as the primary nursing diagnosis in this case.
Question 4
A nurse who works in an outpatient surgical center develops a new respiratory illness. She has atypical symptoms and is not responding to conventional therapies. Her work history includes spending considerable amounts of time in her facility’s central supply and equipment sterilization areas. Her treating physician suspects her illness is linked to a workplace exposure. Where is the best place for the nurse to obtain information regarding her potential workplace exposures?
A. the equipment manufacturer’s service center and help desk
B. the Occupational Safety and Health Administration (OSHA) website
C. the Safety Data Sheets/SDS (formerly referred to as Material Safety Data Sheets/MSDS) at her facility
D. the Centers for Disease Control and Prevention’s (CDC) reportable illness hotline
Show answer and rationale
Correct answer: C — the Safety Data Sheets/SDS (formerly referred to as Material Safety Data Sheets/MSDS) at her facility
The correct answer is C: the Safety Data Sheets/SDS at her facility. This is the best place for the nurse to obtain information regarding her potential workplace exposures because SDS provide detailed information about hazardous chemicals in the workplace, including health effects, protective measures, and exposure control. The nurse can review the SDS for the chemicals used in the central supply and equipment sterilization areas to identify any potential exposures that may be linked to her illness.
Choice A (the equipment manufacturer’s service center and help desk) is incorrect because they may not have specific information on workplace exposures. Choice B (OSHA website) is incorrect because while OSHA provides general workplace safety guidelines, it may not have specific information on the nurse’s workplace exposures. Choice D (CDC’s reportable illness hotline) is incorrect because it is more focused on reporting and tracking infectious diseases, rather than identifying workplace exposures.
Question 5
A nurse is working in a nursing home when there is a fire in the kitchen and cafeteria area. Which of the following is the first priority for the nurse in this situation?
A. Ensure that all patients are moved out of harm’s way.
B. Remove all flammable materials from the area and evacuate to allow firefighters to extinguish the fire.
C. Evacuate all patients from the building immediately.
D. Report to the area of the fire and take measures to extinguish and/or contain it, if possible.
Show answer and rationale
Correct answer: A — Ensure that all patients are moved out of harm’s way.
Step 1: Ensure safety of patients: The first priority of the nurse is to ensure the safety and well-being of the patients in the nursing home.
Step 2: Moving patients out of harm's way: Ensuring all patients are moved out of harm's way is crucial to prevent injuries or casualties.
Step 3: Avoid direct involvement in firefighting: Nurses are not trained firefighters and should not directly engage in extinguishing fires.
Step 4: Wait for firefighters: The nurse should focus on safe evacuation and wait for professional firefighters to handle the fire.
Step 5: Prioritize patient safety over containing the fire: Patient safety is the primary concern, and containing the fire comes after ensuring everyone is safe.
Summary:
- Choice A is correct as it prioritizes patient safety.
- Choice B is incorrect as nurses should not remove flammable materials or engage in firefighting.
- Choice C is incorrect as immediate evacuation without ensuring safety could lead to chaos.
- Choice D is incorrect as nurses

Question 6
You are on the scene of a vehicle accident with entrapment. Why is it so important to ensure the battery has been disconnected before attempting to enter the vehicle or extricate the driver?
A. To make sure the vehicle is not capable of moving during the extrication process and injuring anyone involved
B. To ensure any undeployed airbags do not discharge and cause an injury to the patient or anyone involved
C. To make sure that no one in contact with the vehicle gets electrocuted
D. To prevent the possibility of a fire starting in the passenger compartment during the extrication process
Correct answer:
The correct answer is B: To ensure any undeployed airbags do not discharge and cause an injury to the patient or anyone involved. When a vehicle's battery is not disconnected before attempting to enter or extricate a driver, there is a risk that any undeployed airbags may still be active and could suddenly inflate, potentially causing harm to the patient or anyone involved in the extrication process. Disconnecting the battery eliminates the power source for the airbags, reducing the risk of unintended deployment.
Choice A is incorrect because disconnecting the battery is not primarily done to prevent the vehicle from moving during extrication; other safety measures are in place for that purpose. Choice C is incorrect as the risk of electrocution is minimal if proper extrication procedures are followed. Choice D is incorrect because while a fire is a concern in vehicle accidents, disconnecting the battery is not specifically related to preventing fires in the passenger compartment during extrication.
Which method of intrapartum fetal monitoring is the most appropriate when a woman has a history of hypertension during pregnancy?
A. Continuous auscultation with a fetoscope
B. Continuous electronic fetal monitoring
C. Intermittent assessment with a Doppler transducer
D. Intermittent electronic fetal monitoring for 15 minutes each hour
Correct answer:
The correct answer is B: Continuous electronic fetal monitoring. This method is most appropriate for a woman with a history of hypertension during pregnancy because it allows continuous monitoring of fetal heart rate patterns and uterine contractions, providing real-time data to detect any signs of fetal distress promptly. Continuous monitoring is crucial in high-risk pregnancies to ensure timely intervention if any issues arise.
A: Continuous auscultation with a fetoscope is not ideal for a woman with a history of hypertension as it does not provide continuous monitoring and may miss subtle changes in fetal well-being.
C: Intermittent assessment with a Doppler transducer does not offer continuous monitoring, which is essential in high-risk pregnancies like hypertension.
D: Intermittent electronic fetal monitoring for 15 minutes each hour is not as effective as continuous monitoring in detecting changes in fetal well-being promptly, which is crucial in cases of hypertension during pregnancy.
What role does the nurse assume when given a position of authority within a formal organization?
A. Manager.
B. Advocate.
C. Leader.
D. Teacher.
Correct answer:
The correct answer is A: Manager. When a nurse assumes a position of authority within a formal organization, they are responsible for overseeing operations, resources, and staff to achieve organizational goals. As a manager, the nurse will be involved in decision-making, planning, organizing, and controlling activities within the organization. This role requires skills in delegation, problem-solving, and communication to effectively lead the team.
Incorrect choices:
B: Advocate - While advocacy is an important aspect of nursing, assuming a position of authority typically involves broader responsibilities beyond advocacy.
C: Leader - Leadership qualities are essential for a nurse in a managerial position, but leadership alone does not encompass all the responsibilities of a manager.
D: Teacher - Although teaching may be part of a nurse's role, assuming a position of authority within a formal organization usually entails managerial duties rather than solely focusing on teaching responsibilities.
A client is receiving teaching from a healthcare provider about reducing the adverse effects of immobility. Which of the following statements by the client indicates an understanding of the teaching?
A. I will perform ankle and knee exercises every hour - Range of motion (ROM) is needed to prevent contractures.
B. I will hold my breath when rising from a sitting position.
C. I will remove my antiembolic stockings while I am in bed.
D. I will have my partner help me change positions every 4 hours.
Correct answer:
Choice A is correct because performing ankle and knee exercises every hour helps prevent contractures and other adverse effects of immobility. Contractures are a common complication of immobility, and range of motion (ROM) exercises can help maintain joint flexibility and prevent contractures. This statement indicates an understanding of the teaching provided by the healthcare provider. Choices B, C, and D are incorrect. Holding the breath when rising from a sitting position can increase the risk of orthostatic hypotension, not reduce adverse effects of immobility. Removing antiembolic stockings while in bed can compromise their effectiveness in preventing deep vein thrombosis (DVT), which is not a measure to reduce immobility-related complications. Having a partner help change positions every 4 hours may not be frequent enough to prevent immobility-related complications effectively; changing positions more frequently is usually recommended to prevent issues like pressure ulcers and muscle stiffness.
A 70-year-old man presents with a complaint of difficulty walking. He has a history of Parkinson's disease and is currently taking levodopa. On examination, he has rigidity, bradykinesia, and a shuffling gait. Which of the following is the most likely cause of his symptoms?
A. Parkinson's disease progression
B. Normal aging
C. Cerebellar ataxia
D. Spinal cord compression
Correct answer:
The correct answer is A: Parkinson's disease progression. This is the most likely cause of the patient's symptoms due to his history of Parkinson's disease and the presence of typical Parkinsonian features such as rigidity, bradykinesia, and shuffling gait. Levodopa is a common medication used to manage symptoms of Parkinson's disease. The progression of Parkinson's disease can lead to worsening motor symptoms over time, including difficulty walking.
Option B: Normal aging is incorrect because the patient's symptoms are not solely due to the aging process, but rather are consistent with the known condition of Parkinson's disease.
Option C: Cerebellar ataxia is unlikely as the patient's symptoms align more closely with Parkinsonian features rather than cerebellar dysfunction.
Option D: Spinal cord compression is not the most likely cause as the patient's symptoms are more characteristic of Parkinson's disease progression rather than symptoms typically associated with spinal cord compression.
The nurse is caring for a patient in an intensive care unit who needs a bath. Which priority action will the nurse take to decrease the potential for a health care–associated infection?
A. Use local anesthetic on reddened areas.
B. Use nonallergenic tape on dressings.
C. Use a chlorhexidine wash.
D. Use filtered water.
Correct answer:
The correct answer is C: Use a chlorhexidine wash. This is the priority action to decrease the potential for healthcare-associated infections in an ICU setting. Chlorhexidine is an effective antiseptic that can reduce the risk of infection by killing a wide range of microorganisms on the skin. It is specifically chosen for its ability to provide prolonged antimicrobial activity, making it an essential component in infection prevention protocols. Using a chlorhexidine wash before a bath can significantly reduce the microbial load on the patient's skin, decreasing the risk of infections.
Choice A, using local anesthetic on reddened areas, is not directly related to infection prevention. Choice B, using nonallergenic tape on dressings, is important for preventing allergic reactions but does not address the overall risk of healthcare-associated infections. Choice D, using filtered water, is important for certain procedures but does not target the broader goal of infection prevention in this scenario.
Which primary aspect will the nurse leader focus on when using the new science age for leadership?
A. Relationships
B. Strategic planning
C. Hierarchical organizational structure
D. Task accomplishment
Correct answer:
The correct answer is A: Relationships. In the new science age, nurse leaders will focus on relationships because effective leadership is built on trust, communication, and collaboration. Establishing strong relationships with team members fosters a positive work environment, enhances teamwork, and improves patient outcomes. By prioritizing relationships, nurse leaders can promote a culture of empathy, respect, and support within their teams. This approach also aligns with the principles of transformational leadership, which emphasizes inspiring and motivating team members through interpersonal connections. Therefore, focusing on relationships is crucial for nurse leaders to adapt to the changing landscape of healthcare leadership in the new science age.
Summary:
- Relationships are important for building trust and collaboration in the team.
- Strategic planning, hierarchical structure, and task accomplishment are important but not as fundamental as relationships in the new science age leadership.
You are called to assist a 55-year-old male who complains of sudden onset chest pain, dyspnea, and palpitations. On arrival, he is found semi-conscious with a pulse rate too fast to palpate and a blood pressure of 80 systolic. Once on the monitor, he is exhibiting an irregularly wide complex tachycardia, with a polymorphic QRS appearance, at nearly 200 per minute. Which of the following would be the most effective intervention for this patient?
A. Administer procainamide at 20 mg/min IV infusion, per protocol
B. Administer 6 mg of adenosine IVP, followed by 12 mg, twice for a total of 30 mg, per protocol
C. Administer defibrillation per protocol
D. Administer synchronized electrical cardioversion at 50-100 joules, per protocol
Correct answer:
The correct answer is C: Administer defibrillation per protocol. The patient is presenting with symptoms indicative of unstable ventricular tachycardia or ventricular fibrillation, which are life-threatening arrhythmias. Defibrillation is the immediate intervention to restore normal rhythm by delivering an electrical shock to the heart. In this scenario, the patient is hemodynamically unstable with a low blood pressure and loss of consciousness, making defibrillation the most appropriate and effective intervention to potentially save the patient's life.
Choice A (Administer procainamide) is not the most effective intervention as this patient is in a critical condition that requires immediate action, and procainamide infusion takes time to work.
Choice B (Administer adenosine) is typically used for supraventricular tachycardias and is not appropriate for wide complex tachycardias.
Choice D (Administer synchronized electrical cardioversion) is indicated for stable wide complex tachycardias
The need for university-based nursing education programs was brought to light during which important historical time?
A. Spanish-American War
B. World War I
C. World War II
D. The Civil War
Correct answer:
The evolution of nursing education reflects historical shifts in healthcare demands, and World War II marked a significant turning point. During this period, Esther Lucile Brown's 1940s report highlighted the need for nursing education to move from hospital-based training to colleges and universities, arguing it would elevate the profession's standards and scientific foundation. This shift was driven by the war's demand for skilled nurses in both military and civilian roles, exposing the limitations of earlier apprenticeship models. The Spanish-American War saw nursing in its infancy, while World War I, despite Florence Nightingale's influence, still struggled with professionalization. The Civil War predates these developments, with nursing largely informal. World War II's crisis needs catalyzed a formal push for university-based programs, shaping modern nursing education to meet complex healthcare challenges with a stronger academic base, a legacy that continues to influence the profession today.
A patient suffers from dysmenorrhea. Which oral medication will be prescribed that has the ability to provide physiological actions on the neuroendocrine control of ovarian function?
A. Estrogen
B. Progestins
C. Naprosyn (Naproxen)
D. Ibuprofen (Motrin)
Correct answer:
Dysmenorrhea, painful menstruation, often involves excessive uterine contractions driven by prostaglandins. Progestins, synthetic progesterone derivatives, suppress ovarian function by inhibiting gonadotropin release, reducing estrogen-driven endometrial growth and subsequent prostaglandin production during menses. This neuroendocrine modulation decreases uterine activity, alleviating pain. Estrogen alone wouldn't suppress ovarian function and might exacerbate symptoms by promoting endometrial proliferation. Naproxen and ibuprofen, nonsteroidal anti-inflammatory drugs, relieve pain by inhibiting prostaglandin synthesis but don't alter ovarian function hormonally. Progestins' ability to influence the hypothalamic-pituitary-ovarian axis makes them uniquely suited for this condition, offering both symptom relief and cycle regulation. Their prescription reflects a targeted approach to modify the physiological drivers of dysmenorrhea, providing a comprehensive therapeutic effect beyond mere analgesia.
