2024 PN NCLEX Questions

1. What effect can medication bound to protein have?

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.

2. A nurse calculates a newborn infant's Apgar score 1 minute after birth and determines that the score is 6. What is the most appropriate action for the nurse to take?

Correct answer: B

Rationale: The Apgar score is a method for rapidly evaluating an infant's cardiorespiratory adaptation after birth. The nurse assigns scores in five areas: heart rate, respiratory effort, muscle tone, reflex response, and color, totaling the scores. A score of 8 to 10 requires no action other than supporting the infant's spontaneous efforts and observation. A score of 4 to 7 indicates the need to gently stimulate the infant by rubbing his back while administering oxygen. If the score is 1 to 3, the infant requires resuscitation. Therefore, in this scenario with an Apgar score of 6, the correct action is to gently stimulate the infant by rubbing his back while administering oxygen. Initiating cardiopulmonary resuscitation would be excessive at this point, and rechecking the score in 5 minutes may delay necessary interventions. Providing no action except to support the infant's spontaneous efforts is insufficient for a score of 6, indicating the need for stimulation and oxygen administration.

3. All of the following are common reasons that nurses are reluctant to delegate except:

Correct answer: C

Rationale: The correct answer is 'confidence in subordinates.' If a delegator has confidence in their subordinates' abilities, they are more likely to delegate tasks. Reasons why nurses are reluctant to delegate include their own lack of self-confidence, the desire to maintain authority, and getting trapped in the 'I can do it better myself' mindset. Therefore, having confidence in subordinates is not a common reason for reluctance to delegate.

4. A nurse notes the presence of variable decelerations on the fetal heart rate monitor strip and suspects cord compression. The nurse should immediately perform which action?

Correct answer: B

Rationale: When variable decelerations on the fetal heart rate monitor strip suggest cord compression, the immediate action the nurse should take is to reposition the mother to alleviate the compression. Elevating the mother's hips or changing her position can help shift the fetal presenting part and relieve pressure on the cord. This action aims to improve or resolve the variable decelerations. Contacting the registered nurse may be necessary, but it is not the immediate action required in this situation. Performing a vaginal examination is contraindicated due to the potential risk of further compromising blood flow through the umbilical cord. Inserting a gloved finger into the mother's vagina to feel for the cord is also not recommended as it poses a similar risk of exacerbating the situation.

5. What is the intent of the Patient Self Determination Act (PSDA) of 1990?

Correct answer: B

Rationale: The correct answer is B: The purpose of the PSDA is to encourage medical treatment decision-making before it becomes necessary. This legislation aims to empower individuals to make their own healthcare choices in advance. Choice A is incorrect because while enhancing personal control over healthcare decisions is important, the primary goal of the PSDA is to facilitate medical decision-making before the need arises. Choice C is incorrect as the PSDA does not establish a federal standard for living wills and durable powers of attorney; instead, it encourages individuals to create their own advance directives according to state-specific regulations. Choice D is incorrect because while client education is valuable, the main focus of the PSDA is on empowering individuals to plan for their future healthcare needs.
