Five clinical judgment questions with answers
Cover the key. Write the first action. Then open the rationale and name why the other choices fail.
Question 1
A student nurse tells the instructor, "I'm concerned that when a client asks me for advice I won't have a good solution." Which should be the nursing instructor's best response?
A. "It's scary to feel put on the spot by a client. Nurses don't always have the answer."
B. "Remember, clients, not nurses, are responsible for their own choices and decisions."
C. "Just keep the client's best interests in mind and do the best that you can."
D. "Set a goal to continue to work on this aspect of your practice."
Show answer and rationale
Correct answer: B — "Remember, clients, not nurses, are responsible for their own choices and decisions."
The correct answer is B because it emphasizes the importance of client autonomy and responsibility in decision-making. As a nurse, it is crucial to empower clients to make their own choices and decisions regarding their care. By reminding the student nurse that clients are responsible for their choices, the instructor encourages the student to focus on supporting and guiding the client rather than providing direct advice. This approach aligns with ethical principles of patient-centered care and promotes client empowerment.
Choice A is incorrect because it normalizes not having the answer, which may undermine the student nurse's confidence. Choice C is incorrect as it is vague and does not provide specific guidance on how to address the student's concerns. Choice D is incorrect because it focuses on personal improvement rather than the client's autonomy, which is the key issue in this scenario.
Question 2
A nurse begins work in an agency that provides care to members of a minority ethnic population. The nurse will be better able to demonstrate cultural competence after
A. identifying culture-bound issues.
B. implementing scientifically proven interventions.
C. correcting inferior health practices of the population.
D. exploring commonly held beliefs and values of the population.
Show answer and rationale
Correct answer: D — exploring commonly held beliefs and values of the population.
The correct answer is D because exploring commonly held beliefs and values of the population is essential for cultural competence. By understanding the cultural context of the population, the nurse can provide more effective and respectful care. This includes recognizing traditions, preferences, and communication styles.
A: Identifying culture-bound issues may not necessarily lead to cultural competence as it focuses more on recognizing specific cultural practices rather than understanding the broader cultural context.
B: Implementing scientifically proven interventions is important but does not directly relate to cultural competence, which requires a deeper understanding of cultural nuances.
C: Correcting inferior health practices of the population is ethnocentric and disrespectful, going against the principles of cultural competence that emphasize respect for diverse beliefs and practices.
Question 3
A man died from an acute disease characterized by fever, jaundice, hemorrhagic rash, and acute renal insufficiency. Histological examination revealed spiral bacteria shaped like 'C' and 'S' letters. Identify the pathogen.
A. Leptospira
B. Treponema
C. Borrelia
D. Spirochaeta
Show answer and rationale
Correct answer: A — Leptospira
The correct answer is A: Leptospira. Leptospira is a spiral-shaped bacterium that causes a disease known as leptospirosis, characterized by fever, jajsondice, hemorrhagic rash, and renal insufficiency. The characteristic spiral shape of the bacteria, resembling 'C' and 'S' letters, is a key identifying feature. Leptospira is commonly associated with contaminated water sources and can be transmitted to humans through contact with infected animals or water.
Summary of other choices:
B: Treponema - Treponema pallidum is the causative agent of syphilis, which does not typically present with the combination of symptoms described in the question.
C: Borrelia - Borrelia species are associated with Lyme disease and relapsing fever, but do not match the specific symptoms and histological appearance described in the question.
D: Spirochaeta - Spirochaeta is a genus of bacteria, but specific species within
Question 4
In the process of muscle contraction, what happens when ATP binds to the myosin head?
A. The myosin head releases calcium ions and returns to its resting position
B. ATP hydrolysis causes the myosin head to attach to the actin filament
C. ATP binds to the myosin head, breaking the cross-bridge and allowing the myosin to detach from actin
D. ATP facilitates the release of acetylcholine at the neuromuscular junction
Show answer and rationale
Correct answer: C — ATP binds to the myosin head, breaking the cross-bridge and allowing the myosin to detach from actin
During muscle contraction, the cross-bridge cycle drives filament sliding. After myosin binds to actin and performs a power stroke pulling actin toward the sarcomere's center ATP binds to the myosin head. This binding reduces myosin's affinity for actin, breaking the cross-bridge and detaching myosin, allowing it to reset for another cycle. ATP is then hydrolyzed to ADP and phosphate, cocking the head into a high-energy state to reattach to actin. Calcium ions, managed by the sarcoplasmic reticulum, regulate actin exposure, not myosin detachment. Acetylcholine release occurs at the neuromuscular junction, unrelated to ATP's role here. Hydrolysis energizes myosin but doesn't cause attachment binding does the detachment. This ATP-driven detachment is critical for repeated contractions, distinguishing it from initiation or calcium-related steps, and underscores its mechanical role in muscle dynamics.
Question 5
Icterus gravis and hydrops fetalis are conditions highly associated with:
A. Rhesus D incompatibility
B. ABO incompatibility
C. Physiological jaundice
D. Instant perinatal death
Show answer and rationale
Correct answer: A — Rhesus D incompatibility
The correct answer is A: Rhesus D incompatibility. Icterus gravis (severe jaundice) and hydrops fetalis (abnormal accumulation of fluid) are both conditions commonly associated with Rhesus D incompatibility between a mother and her fetus. This occurs when the mother is Rh-negative and the fetus is Rh-positive, leading to maternal antibodies attacking the fetal red blood cells, resulting in severe hemolytic anemia and subsequent complications.
Explanation for why other choices are incorrect:
B: ABO incompatibility typically leads to less severe jaundice and hemolytic disease compared to Rhesus D incompatibility.
C: Physiological jaundice is a common and benign condition in newborns caused by the immaturity of the liver, not by blood type incompatibility.
D: Instant perinatal death is not specifically associated with these conditions, but rather with other serious complications during childbirth.

Question 6
A patient with schizophrenia has received typical (first-generation) antipsychotics for a year. His hallucinations are less intrusive, but he remains apathetic, has poverty of thought, cannot work, and is socially isolated. To address these symptoms, the nurse might consult the prescribing health care provider to suggest a change to:
A. Haloperidol (Haldol).
B. Olanzapine (Zyprexa).
C. Diphenhydramine (Benadryl).
D. Chlorpromazine (Thorazine).
Correct answer:
The correct answer is B: Olanzapine (Zyprexa). Olanzapine is an atypical (second-generation) antipsychotic that has been shown to effectively target negative symptoms of schizophrenia, such as apathy, poverty of thought, and social isolation. It also helps with mood stabilization and cognitive function, which can improve the patient's ability to work and engage in social interactions.
Choice A: Haloperidol (Haldol) is a typical (first-generation) antipsychotic like the current medication, which is less effective in treating negative symptoms and can potentially worsen them.
Choice C: Diphenhydramine (Benadryl) is an antihistamine and not indicated for treating schizophrenia symptoms.
Choice D: Chlorpromazine (Thorazine) is another typical (first-generation) antipsychotic, similar to the current medication, and may not adequately address the negative symptoms the patient is experiencing.
A client in the third trimester of pregnancy reports that she feels some 'lumpy places' in her breasts and that her nipples sometimes leak a yellowish fluid. She has an appointment with her healthcare provider in two weeks. What action should the nurse take?
A. Instruct the client to immediately see her provider for an evaluation
B. Assess the fluid for signs of infection
C. Explain that this normal secretion can be assessed at the next visit
D. Recommend breast ultrasound to rule out abnormalities
Correct answer:
The yellowish fluid is likely colostrum, a normal finding in late pregnancy as the breasts prepare for lactation. It is common for women in the third trimester to experience 'lumpy places' in the breasts due to increased milk duct development. In this situation, the nurse should educate the client that these findings are normal physiological changes associated with pregnancy. Since the client has an upcoming appointment with her healthcare provider in two weeks, it is appropriate to reassure her that this can be further assessed during that visit. Instructing the client to immediately see her provider (Choice A) is unnecessary as this is a common finding in late pregnancy. Assessing the fluid for signs of infection (Choice B) is not warranted as colostrum leakage is a normal occurrence. Recommending a breast ultrasound (Choice D) is premature without further assessment by the healthcare provider.
While studying the pneumonic infection in 1928 the English doctor Frederick Griffith discovered:
A. Translation
B. Transformation
C. Transcription
D. Conjugation
Correct answer:
The correct answer is B: Transformation. Frederick Griffith discovered bacterial transformation, where genetic material can be transferred between bacteria. He observed this phenomenon while studying pneumonia-causing bacteria in 1928. Transformation is the process by which bacteria take up external DNA and incorporate it into their own genome. This discovery was crucial in understanding how genetic information can be transferred between organisms.
Rationale for other choices:
A: Translation - This term refers to the process of protein synthesis from mRNA, not relevant to Griffith's discovery.
C: Transcription - This term refers to the process of synthesizing RNA from DNA, not related to Griffith's discovery.
D: Conjugation - This term refers to the direct transfer of genetic material between bacterial cells through cell-to-cell contact, which is different from the phenomenon Griffith observed.
The nurse cares for a client with hypertension, and a nurse–client contract is developed outlining the activities and responsibilities of each. Which would be appropriate to include in this contract? (Select all that apply)
A. The outcomes should be realistic and measurable.
B. Progress should be reviewed at regular intervals.
C. The contract should be written and signed.
D. The nurse should keep the information confidential.
Correct answer:
The correct answer is A: The outcomes should be realistic and measurable. This is appropriate to include in the nurse-client contract because setting realistic and measurable outcomes helps in monitoring progress and evaluating the effectiveness of interventions in managing hypertension. It allows for clear communication between the nurse and the client regarding the goals of treatment.
Incorrect choices:
B: Progress should be reviewed at regular intervals - While this is important in the management of hypertension, it is a process rather than a specific component of a contract.
C: The contract should be written and signed - This is important for legal purposes but not specifically related to setting goals and outcomes.
D: The nurse should keep the information confidential - This is a standard ethical practice but not a specific component of a contract outlining activities and responsibilities.
Sputum smears of a patient with chronic pulmonary disease were stained by Ziehl-Neelsen method and analyzed in the bacteriological laboratory. Microscopy revealed red bacillus. What property of tuberculosis myobacteria was found?
A. Acid resistance
B. Alkali resistance
C. Alcohol resistance
D. Encapsulation
Correct answer:
The correct answer is A: Acid resistance. Tuberculosis mycobacteria have a unique cell wall structure that makes them resistant to acid-fast staining methods like Ziehl-Neelsen. This is due to the high lipid content of their cell walls, specifically mycolic acids, which prevent the penetration of stains and acids. The red bacilli observed in the smear indicate that the mycobacteria retained the primary stain (carbolfuchsin) after acid-alcohol decolorization, confirming their acid resistance.
Summary:
- Choice A: Acid resistance is correct due to the unique cell wall structure of tuberculosis mycobacteria.
- Choice B: Alkali resistance is incorrect as mycobacteria are not known for being resistant to alkalis.
- Choice C: Alcohol resistance is incorrect as mycobacteria are not specifically resistant to alcohols.
- Choice D: Encapsulation is incorrect as mycobacteria are not encapsulated bacteria.
A couple comes in for an infertility workup, having attempted to get pregnant for 2 years. The woman, 37, has always had irregular menstrual cycles but is otherwise healthy. The man has fathered two children from a previous marriage and had a vasectomy reversal 2 years ago. The man has had two normal semen analyses, but the sperm seem to be clumped together. What additional test is needed?
A. FSH level
B. Antisperm antibodies
C. Testicular biopsy
D. Test of testicular infection
Correct answer:
The correct answer is B: Antisperm antibodies. In this case, the man's history of vasectomy reversal and normal semen analyses with clumped sperm suggest a possible presence of antisperm antibodies. These antibodies can cause sperm agglutination, affecting fertility. Testing for antisperm antibodies can provide valuable information on potential immune-related infertility issues.
A: FSH level is not the most appropriate test in this scenario as the man's semen analyses were normal, indicating potential issues with sperm-egg interaction rather than hormonal imbalances.
C: Testicular biopsy is invasive and not necessary at this stage when the issue seems to be related to sperm clumping rather than a structural problem within the testes.
D: Test of testicular infection is unlikely as the man's semen analyses were normal, and there are no indications of infection based on the information provided.
What complications can cocaine and methamphetamine use in pregnancy cause?
A. seizures
B. hypotonic contractions
C. prolonged second stage labor
D. prolonged first stage labor
Correct answer:
The correct answer is C: Prolonged second stage labor. Cocaine and methamphetamine use in pregnancy can lead to vasoconstriction, decreased blood flow to the uterus, and reduced oxygen supply to the fetus, resulting in uterine hyperactivity and fetal distress during labor. This can cause the second stage of labor to be prolonged as the uterus may struggle to effectively contract and progress labor.
Explanation for other choices:
A: Seizures - While cocaine and methamphetamine use can lead to seizures in pregnant individuals, this is not directly related to labor complications.
B: Hypotonic contractions - Cocaine and methamphetamine use are more likely to cause hypertonic contractions (excessive uterine contractions) rather than hypotonic contractions.
D: Prolonged first stage labor - Cocaine and methamphetamine use are more likely to impact the second stage of labor rather than the first stage.
A patient was recently diagnosed with pneumonia. The nurse and the patient have established a goal that the patient will not experience shortness of breath with activity in 3 days with an expected outcome of having no secretions present in the lungs in 48 hours. Which evaluative measure will the nurse use to demonstrate progress toward this goal?
A. No sputum or cough present in 4 days
B. Congestion throughout all lung fields in 2 days
C. Shallow, fast respirations 30 breaths per minute in 1 day
D. Lungs clear to auscultation following use of inhaler
Correct answer:
The correct evaluative measure is D: Lungs clear to auscultation following use of inhaler. This choice aligns with the expected outcome of having no secretions present in the lungs in 48 hours. By using an inhaler to clear the lungs, the nurse can assess if the expected outcome is being met. This measure directly evaluates the presence of secretions in the lungs, in line with the established goal.
Incorrect Choices:
A: No sputum or cough present in 4 days - This measure does not align with the expected outcome of having no secretions present in the lungs in 48 hours.
B: Congestion throughout all lung fields in 2 days - This indicates a worsening condition and does not demonstrate progress towards the goal.
C: Shallow, fast respirations 30 breaths per minute in 1 day - This measure is unrelated to the presence of secretions in the lungs and the goal of avoiding shortness of breath with activity.
Mr. Kawasaki, a 23-year old industrial worker, was burned severely in an industrial accident. He has second degree burns on his right leg and arm, and on his left leg. He has third degree burns on his left arm. The triage nurse, using the rule of nines, estimates the extent of burn as:
A. 18%
B. 45%
C. 36%
D. 54%
Correct answer:
The rule of nines is a method used to estimate the extent of burns on a patient's body. According to this rule, each major body part is assigned a percentage value that represents the total body surface area (TBSA). In this case, Mr. Kawasaki has second-degree burns on his right leg and arm (9% each) and left leg (9%) and third-degree burns on his left arm (9%). Adding these percentages together, we get a total of 36%, which corresponds to the extent of burn on Mr. Kawasaki's body.
Choice A (18%) is incorrect because it only considers one arm and one leg, neglecting the other affected areas. Choice B (45%) is incorrect as it overestimates the extent of burns by including additional body parts not affected. Choice D (54%) is also incorrect as it includes more body parts than those actually burned. Therefore, the correct answer is C (36%) as it accurately reflects the distribution of burns based
Which of the following statements about the outer layer of the eye is true?
A. The outer layer of the eye is very sensitive to touch.
B. The outer layer of the eye is darkly pigmented to prevent light from reflecting internally.
C. The trigeminal (CN V) and the trochlear (CN IV) nerves are stimulated when the outer surface of the eye is stimulated.
D. The visual receptive layer of the eye in which light waves are changed into nerve impulses is located in the outer layer of the eye.
Correct answer:
The correct answer is C because the trigeminal (CN V) and the trochlear (CN IV) nerves are indeed stimulated when the outer surface of the eye is stimulated. The trigeminal nerve is responsible for the sensation of touch in the face and controls the muscles involved in chewing. The trochlear nerve controls the superior oblique muscle of the eye, which helps with downward and inward eye movements. Therefore, when the outer layer of the eye is touched or stimulated, these nerves are activated to convey the sensation to the brain.
Choices A, B, and D are incorrect:
A: The outer layer of the eye is not particularly sensitive to touch compared to other areas like the cornea or conjunctiva.
B: The outer layer of the eye is not darkly pigmented; the pigmented layer is actually the uvea inside the eye.
D: The visual receptive layer of the eye, known as the retina, is located deeper within the eye, not
