Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?

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: 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: A

Rationale: For a 5-year-old child, dental examinations should be conducted every 6 months. This frequency allows for early detection of dental issues and promotes good oral health. Choices B, C, and D are incorrect because waiting for a new primary tooth to erupt, having an examination once a year, or every 3 months are not the recommended intervals for dental check-ups in this age group. It is essential to adhere to the standard guideline of every 6 months to ensure regular monitoring and preventive care for the child's dental health.

Correct Answer: B

Rationale: According to Erikson's theory of psychosocial development, the primary task for an 8-year-old child aligns with the stage of industry versus inferiority. This stage focuses on mastering useful skills and tools of the culture, emphasizing competence in various areas. Option A, 'Developing a sense of control over self and body functions,' is more characteristic of the toddler stage, emphasizing autonomy and self-regulation. Option C, 'Gaining independence from parents,' is more relevant to the adolescent stage, where identity development and autonomy become crucial. Option D, 'Developing a sense of trust in the world,' pertains to the infant stage, highlighting the importance of forming secure attachments. Therefore, the correct answer is B as it directly corresponds to the developmental tasks associated with an 8-year-old child according to Erikson's theory.

Correct Answer: A

Rationale: School-age children are capable of taking responsibility for their own dental hygiene. Establishing good oral health habits during childhood can lead to a lifetime of cavity prevention. The nurse advises the parents that their children should brush with fluoride toothpaste and floss between their teeth after meals and before bedtime. This routine helps maintain good oral health and teaches children the importance of dental care. Choice A is the correct answer as it emphasizes both brushing and flossing after meals and at bedtime, which are crucial for effective dental care. Choices B, C, and D are incorrect as they do not stress the significance of both brushing and flossing after meals, which is essential for proper oral hygiene.
