Correct Answer: B

Rationale: An FHR of 160 beats/min in the first trimester of pregnancy is within the normal range, which is generally 120 to 160 beats/min. The appropriate action for the nurse in this situation is to document the findings. There is no need to notify the healthcare provider as this is a normal finding. Informing the client that the FHR is faster than normal may cause unnecessary anxiety, as it falls within the expected range. Waiting to recheck the FHR is not necessary since the rate is already within the normal range.

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: B

Rationale: When auscultating the fetal heart rate, the nurse would place the fetoscope on the maternal abdomen, over the fetal back. The nurse would then palpate the mother's radial pulse. If her pulse is synchronized with the sounds from the fetoscope, the nurse would move the fetoscope to another area on the mother's abdomen to locate the FHR. The nurse needs to be sure that the FHR is what is actually being heard. Other sounds that may be heard are the funic sound (blood flowing through the umbilical cord) and the uterine sound (blood flowing through the uterine vessels). The funic sound is synchronized with the FHR; the uterine sound is synchronized with the mother's pulse. Therefore, moving the fetoscope to a different area will help in accurately locating and counting the fetal heart rate. Choice A is incorrect because counting for 60 seconds without changing the position may not address the issue of accurately locating the FHR. Choice C is incorrect as it does not address the need to reposition the fetoscope to locate the fetal heart. Choice D is incorrect because counting the FHR and the radial pulse rate separately may not help in differentiating the two sounds.

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: B

Rationale: The correct answer is to give the medications sequentially and flush well between them. Ampicillin has a pH of 8-10, while gentamicin has a pH of 3-5.5, making them incompatible when given together. Flushing well between drugs is necessary to prevent any potential interactions. Option A is incorrect because administering both medications simultaneously can lead to incompatibility issues. Option C is incorrect because the nurse should already be aware of the correct administration sequence and not need to consult the physician or pharmacy each time. Option D is incorrect because delaying the second medication by several hours can slow down the treatment of the client's infection, which is not ideal in this scenario.
