Correct Answer: A

Rationale: The best response for the nurse when an elder client asks about capability for sexual activity in old age is to provide reassurance and open communication. Choice A is the correct answer as it acknowledges that elder adults can engage in sexual activity both physically and psychologically despite age-related changes. This response encourages further discussion and addresses the client's concerns. Choices B, C, and D contain some truths but are not the most therapeutic responses. Choice B implies that past sexual activity is a prerequisite for sexual activity in old age, which is not entirely accurate as intimacy can be experienced in various ways. Choice C, while true about alternative ways to meet sexual needs, does not directly address the client's question about sexual activity. Choice D focuses on the physiological aspect of sexual function, which is important but not the most appropriate initial response to the client's query.

Correct Answer: D

Rationale: The tissue that would receive the highest amount of cardiac output and thus the highest amount of a drug is the myocardium. Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being part of the heart, receives a significant amount of cardiac output. Choices A (skin) and B (adipose tissue) are poorly perfused tissues and would not receive high amounts of cardiac output. Choice C (skeletal muscle) is also less perfused compared to the myocardium.

Correct Answer: A

Rationale: For clients with dysphagia, ensuring successful swallowing of food and preventing aspiration is crucial. Therefore, the nurse should suggest monitoring the client closely during meals to provide assistance as needed. While a balanced diet is important, special considerations like adding thickeners for liquids may be required for dysphagia clients. Consulting with a physician about enteral tube feeding should be based on the severity of the condition, making it a premature step without clear indications. Encouraging self-feeding may not be appropriate for dysphagia clients who require close monitoring and assistance, as it could increase the risk of complications.

Correct Answer: A

Rationale: The head circumference growth rate during the first year is approximately 0.4 inches (1 cm) per month. By 10 to 12 months of age, the infant's head and chest circumferences are equal. In this case, where the head circumference matches the chest circumference, it is a normal finding in infants around 10-12 months. Therefore, the most appropriate action is to document these measurements in the infant's health care record. Suspecting hydrocephalus or suggesting a skull x-ray would be premature and not indicated based on this measurement. Similarly, telling the mother that the infant is growing faster than expected is not accurate and could cause unnecessary concern.

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.
