Correct Answer: A

Rationale: When discussing birth control methods with a client, a nurse should focus on the client's personal preference as a major factor that will provide the motivation needed for consistent implementation of a birth control method. Personal preference plays a key role in ensuring that the chosen method aligns with the client's lifestyle and values, increasing the likelihood of adherence. While work and home schedules, family planning goals, and the desire to have children in the future can influence the choice of birth control method, they are not the primary motivating factors for consistent implementation. Personal preference is crucial as it empowers the client to select a method that suits their individual needs and preferences, ultimately leading to better compliance and effectiveness.

Correct Answer: C

Rationale: The correct advantage of using CVADs for chemotherapeutic agent administration is that chemotherapeutic agents can be caustic to smaller veins. Many chemotherapeutic drugs are vesicants, which can cause tissue damage even in low concentrations. Using a CVAD to administer these agents into a large vein is optimal as it reduces the risk of damage. Choice A is incorrect as CVADs are actually more expensive than a peripheral IV, making it a disadvantage. Choice B is incorrect because the frequency of administration depends on the specific drug being administered, not on the access device, so it does not represent a universal advantage. Choice D is incorrect because IV chemotherapeutic agents are typically not self-administered at home; they are usually given in a hospital, outpatient, or clinic setting, making it an invalid advantage of using CVADs.

Correct Answer: A

Rationale: To help maintain an adequate sleep pattern in older clients, it is essential to include activities that promote relaxation and a conducive sleep environment. Encouraging bedtime reading or listening to music can help the client unwind and prepare for sleep. Daytime naps should be discouraged to ensure a better nighttime sleep. Social interaction, especially positive interactions, can be beneficial and should not be discouraged. The use of a nightlight can create a safe and comfortable environment for the client, so it should not be discouraged unless specifically contraindicated.

Correct Answer: B

Rationale: To assess the fetal heart rate of a client who is 14 weeks pregnant, the nurse should use a Doppler transducer. Fetal heart sounds can be heard with a fetoscope by 20 weeks of gestation. The Doppler transducer amplifies fetal heart sounds so that they are audible by 10 to 12 weeks of gestation, making it the most appropriate choice for this scenario. Fetal heart sounds cannot be heard with a stethoscope. Pulse oximetry is not used to auscultate fetal heart sounds, so it is an incorrect choice in this context.

Correct Answer: D

Rationale: The correct action in this scenario is to call the surgical area and explain that the surgery will have to be cancelled. The client must sign the operative permit or any other legal document before receiving preoperative medication. Without the signed permit, the surgery cannot proceed to ensure the client's safety and legal compliance. Having the client sign the permit, witnessing the form after the client signs it, or having someone else sign the form are all inappropriate actions and do not address the legal requirement of the client's signature before receiving preoperative medication.
