Correct Answer: D

Rationale: When a nurse observes senile tremors, such as intentional tremor of the hands in a client in later adulthood, it is important to document the findings. Senile tremors are benign and a normal age-related occurrence. Referring the client to a neurological specialist (Choice A) is unnecessary as senile tremors do not require specialized neurological intervention. Prescribing a muscle relaxant (Choice B) is not indicated since senile tremors are benign and not typically treated with muscle relaxants. Notifying the healthcare provider immediately (Choice C) is unnecessary as senile tremors do not require urgent intervention. Therefore, the most appropriate action is to document the findings (Choice D) for the client's medical record and to establish a baseline for future assessments.

Correct Answer: B

Rationale: In this scenario, since the couple has indicated that their family-planning goals have been met, a permanent method of contraception like sterilization would be most suitable. Sterilization offers long-term effectiveness and convenience once the decision to stop having children is made. Options like the diaphragm, male condom, or spermicide are more suitable for temporary contraception or when the family-planning goals have not yet been achieved. Therefore, the correct answer is sterilization, as it aligns with the couple's need for a convenient and permanent birth control method.

Correct Answer: D

Rationale: When educating an obese client about nutritional needs and weight loss, it is important to cover factors such as knowledge of food and food products, the development of a positive mental attitude, and the importance of adequate exercise. These aspects contribute to a holistic approach to weight management. However, recommending the client to start a fast weight-loss diet should not be included. Fast weight-loss diets can be harmful, leading to health risks, nutrient deficiencies, and unsustainable outcomes. It is crucial to advocate for gradual, sustainable weight loss strategies to ensure long-term success and overall well-being. Therefore, starting a fast weight-loss diet is the least appropriate option among the choices provided.

Correct Answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, heparin sodium, is an anticoagulant and is not used for flushing IV devices before and after blood administration.

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.
