LPN exams fundamentals practice questions set 44

Correct answer:

The correct answer is A: Unruptured membranes. Internal monitoring devices are inserted through the cervix and into the uterus, which can introduce bacteria and increase the risk of infection if the membranes are not ruptured. This can lead to serious complications for both the mother and the baby. Choice B (intravenous fluid) is incorrect because IV fluids are commonly used during labor to maintain hydration and provide necessary nutrients. Choice C (Fetus has known heart defect) is incorrect because internal monitoring devices are used to assess fetal heart rate and detect any abnormalities, making this condition a reason for monitoring rather than a contraindication. Choice D (must act quickly to improve placental blood flow and fetal oxygen supply) is incorrect because internal monitoring devices are usually used for continuous monitoring and do not require immediate intervention to be placed.

Correct answer:

Step-by-step rationale for why answer A is correct: In a conflict situation, conducting a dynamic risk assessment helps respond appropriately to the perceived threat by evaluating the evolving circumstances and adjusting strategies accordingly. This proactive approach allows for effective decision-making and risk management in real-time, enhancing overall safety and conflict resolution. Summary of why other choices are incorrect: B: Analyzing how the threat was triggered is important for understanding the root cause but may not directly address the immediate threat in a dynamic situation. C: Ensuring customer concerns are addressed is essential for customer service but may not directly relate to mitigating risks in a conflict situation. D: Reducing the likelihood of feeling intimidated is important for personal well-being but may not be the primary goal of a dynamic risk assessment in conflict management.

Correct answer:

Beyond critical thinking, advocating for the client at all times is a cornerstone of nursing success, reflecting the profession's core commitment to patient welfare. This involves ensuring clients' needs, rights, and preferences are prioritized in all care decisions, fostering trust and empowerment. Good teamwork and team-building skills are valuable for collaboration but are learned and applied contextually, not as intrinsic as advocacy. A master's degree enhances expertise but isn't required for foundational success, as many nurses excel with lesser credentials. Delegation is a skill that supports efficiency, yet it's secondary to the nurse's role as a client advocate. Advocacy drives nursing's caring ethos, addressing health needs across diverse settings and populations, making it a vital characteristic that complements critical thinking in achieving optimal outcomes and upholding professional integrity.

Correct answer:

The correct answer is A: Assist the patient to identify triggers to binge eating. The highest priority for a patient with bulimia nervosa is addressing the root cause of the behavior, which is often triggered by emotional or situational factors. By identifying triggers, the patient can learn to recognize and manage them effectively, ultimately reducing the frequency of binge eating episodes. This intervention focuses on addressing the underlying issue and promoting long-term recovery. Summary: B: Providing remedial consequences for weight loss is not the priority as the main concern is addressing the binge eating behavior. C: Assessing for signs of impulsive eating is important, but identifying triggers takes precedence in addressing the behavior. D: Exploring needs for health teaching may be relevant, but addressing triggers to binge eating is more immediate and crucial for managing bulimia nervosa.

Correct answer:

The correct answer is C: Recognizing triggers that cause asthma attacks. This is the priority goal because identifying triggers helps the client avoid or minimize asthma attacks, leading to better management of the condition. By recognizing triggers, the client can take proactive measures to prevent exacerbations. Choices A, B, and D are important aspects of asthma management, but recognizing triggers is crucial for preventing asthma attacks and improving overall quality of life. Maintaining a regular exercise routine (A) can be beneficial but may not be the priority if triggers are not controlled. Complying with medication instructions (B) is important for treatment adherence, but identifying triggers can help reduce the need for rescue medications. Understanding physical limitations (D) is important for self-management, but recognizing triggers is more directly related to preventing asthma exacerbations.

Correct answer:

The correct answer is D because elevating the thighs and lower legs above the heart level promotes venous return and reduces swelling in the affected leg, aiding in the prevention of complications related to venous thromboembolism. Placing one pillow under the thighs and two pillows under the lower legs ensures proper elevation and support. A: Placing the bed in Trendelenburg position isn't appropriate as it involves the head being lower than the feet, which could increase pressure on the lower extremities and potentially worsen the condition. B: Placing two pillows under the calf of the affected leg doesn't provide sufficient elevation for optimal venous return and may not effectively reduce swelling. C: Elevating only at the knee and placing pillows under both feet may not adequately elevate the lower extremities above heart level, limiting the effectiveness of venous return and swelling reduction.

Correct answer:

The correct answer is A: Performing oral care with chlorhexidine. This intervention is most effective for preventing VAP because it helps reduce the colonization of pathogenic bacteria in the oral cavity, which can be aspirated into the lungs. Chlorhexidine is an antiseptic agent that can effectively reduce the risk of developing pneumonia. Summary of other choices: B: Changing ventilator tubing every shift - While maintaining clean ventilator tubing is important for infection prevention, it is not the most effective intervention for preventing VAP. C: Suctioning the patient hourly - Frequent suctioning may be necessary for airway clearance, but it is not specifically targeted at preventing VAP. D: Keeping the patient sedated continuously - Continuous sedation may lead to complications such as prolonged ventilation and increased risk of pneumonia. It is not a recommended strategy for preventing VAP.

Correct answer:

The Mantoux test, used to screen for tuberculosis exposure, requires precise administration to ensure accurate results. It involves injecting purified protein derivative (PPD) intradermally into the inner forearm, creating a small wheal just under the skin surface. This method targets the dermal layer where immune cells can react to the antigen, producing a measurable induration if the child has been exposed to TB. Intramuscular injections into the vastus lateralis or subcutaneous injections into the umbilical area or deltoid are inappropriate because they deliver the substance too deeply or into fatty tissue, preventing the localized skin reaction needed for interpretation. The intradermal technique, typically at a 5-15 degree angle with a fine needle, ensures the PPD remains in the dermis, maximizing sensitivity and specificity of the test, which is critical for early detection in a pediatric population.

Correct answer:

Subjective data consists of information reported by the patient, reflecting their personal experiences, sensations, or perceptions, which cannot be directly measured by the nurse. The statement 'I feel pain when urinating' is a classic example, as it conveys the patient's subjective sensation of pain, reliant on their verbal report rather than objective observation. This type of data is crucial for understanding symptoms like pain or discomfort that lack visible signs. In contrast, a heart rate of 68 beats per minute is objective, measurable via pulse check. Yellowish sputum and noisy breathing are also objective, observable through sight and sound during assessment. Subjective data, like the patient's pain report, enhances the nurse's ability to assess holistic needs, guiding further inquiry or intervention, such as checking for urinary tract issues, making it distinct from observable, objective findings.

Correct answer:

The correct answer is C: A 30-year-old male with hypotension, JVD, and tracheal deviation after chest trauma. This patient most likely has tension pneumothorax, a life-threatening condition where air accumulates in the pleural space causing mediastinal shift, JVD, and hypotension. Needle decompression is the initial treatment to relieve pressure and restore lung function. A: A chest wall contusion with absent breath sounds suggests a potential rib fracture but not a tension pneumothorax. B: Bilateral wheezing and difficulty breathing are more indicative of an asthma exacerbation or COPD exacerbation, not tension pneumothorax. D: Chest pain and productive cough are more commonly associated with conditions like pneumonia or bronchitis, not tension pneumothorax. In summary, the key features of tension pneumothorax are hypotension, JVD, and tracheal deviation after chest trauma, necessitating needle
