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 is preparing to assist the healthcare provider in performing an internal gynecological examination of a client. In which position does the nurse place the client for this examination?

Correct answer: D

Rationale: An internal gynecological examination is performed with the client in the lithotomy position. In this position, the client is supine, with the feet in stirrups, the knees apart, and the buttocks at the end of the examining table. The client is draped so that only the vulva is exposed. The lithotomy position provides optimal access for the healthcare provider to perform the examination effectively. The prone position refers to lying on the stomach, which is not suitable for a gynecological exam. The Sims position is a left side-lying position primarily used for administering enemas, not for gynecological examinations.

3. A nurse assisting with data collection of the peripheral vascular system performs the Allen test. The nurse understands that this test is used to determine the patency of which blood vessel(s)?

Correct answer: D

Rationale: The nurse performs the Allen test to determine the patency of the radial and ulnar arteries. During the test, the nurse applies pressure over the client's ulnar and radial arteries simultaneously. The client is then asked to open and close the hand repeatedly, causing the hand to blanch. Subsequently, the nurse releases pressure from the ulnar artery while compressing the radial artery and checks the color of the extremity distal to the pressure point. If pinkness fails to return within 6 seconds, it indicates that the ulnar artery is insufficient, suggesting that the radial artery should not be used for obtaining a blood specimen. Choice A (Capillaries) is incorrect as the Allen test assesses the patency of larger arteries, not capillaries. Choice B (Pedal pulses) is incorrect as the Allen test specifically evaluates the radial and ulnar arteries, not the pedal pulses in the foot. Choice C (Femoral arteries) is incorrect as the Allen test focuses on the radial and ulnar arteries in the hand, not the femoral arteries in the leg.

4. What is the primary theory that explains a family's concept of health and illness?

Correct answer: A

Rationale: The correct answer is the Health Belief Model. The Health Belief Model is a widely recognized theory that explains individuals' perceptions and behaviors related to health and illness. It considers factors such as perceived susceptibility, severity of health issues, benefits of action, and barriers to taking action. Choices B, C, and D are incorrect. Choice B, 'Education Factor,' is too general and does not specifically address a family's concept of health and illness. Choice C, 'Family Health Belief Model,' is a combination of terms and not a recognized theory. Choice D, 'Family Dynamics Model,' focuses on family interactions rather than explaining a family's concept of health and illness.

5. The mother of a toddler asks the nurse when she will know that her child is ready to start toilet training. The nurse tells the mother that which observation is a sign of physical readiness?

Correct answer: B

Rationale: Signs of physical readiness for toilet training include the child's ability to remove his or her own clothing. This ability indicates the child has developed the necessary fine motor skills to manage clothing during toilet training. The other choices are incorrect because temper tantrums, walking for a specific period, and using utensils are not indicators of physical readiness for toilet training.
