Correct Answer: D

Rationale: The correct answer is medication instruction. This is a skilled service that requires specialized knowledge and training to provide proper guidance on medication management for a client with type I diabetes. Grocery shopping, house cleaning, and transportation services are considered unskilled services as they are typically offered by volunteer or fee-for-service agencies and do not require specialized medical expertise. Medication instruction, on the other hand, involves educating the client on how to properly take medications, understand potential side effects, and manage their medication regimen effectively, which necessitates a high level of expertise and training.

Correct Answer: A

Rationale: The corrected answer is A: Young adults may ignore physical symptoms and postpone seeking health care. Young adults are usually quite active, experience severe illnesses less commonly than members of older age groups, tend to ignore physical symptoms, and often postpone seeking health care. Clients in this developmental stage may benefit from a personal lifestyle assessment to identify habits that increase the risk for various chronic diseases. Choice B is incorrect because the ability to afford health insurance is not the primary reason for conducting a personal lifestyle assessment. Choice C is incorrect because young adults are not inherently at higher risk for serious illness compared to other age groups. Choice D is incorrect because exposure to hazardous substances is not the main focus when conducting a personal lifestyle assessment.

Correct Answer: A

Rationale: The correct answer is 'A loss of melanin occurs in the normal aging process.' Graying hair in older adults is primarily due to a decrease in the number of melanocytes responsible for providing pigment and hair color. This reduction in melanin production leads to gray hair. The other choices are incorrect. While it is true that the skin becomes thinner with aging and the number of sweat glands and blood vessels decreases, these changes are not directly related to graying hair. Additionally, hereditary factors can influence when graying starts, but they do not cause the graying of hair itself.

Correct Answer: C

Rationale: According to Erikson's developmental theory, the primary developmental task of the middle adult is to achieve generativity. Generativity is the willingness to care for and guide others. Middle adults can achieve generativity with their own children or the children of close friends or through guidance in social interactions with the next generation. Providing guidance during interactions with his children aligns with this developmental task. Choices A, B, and D are not specific to the middle adult stage as they are tasks associated with young adults. Redefining self-perception and capacity for intimacy, making decisions concerning career, marriage, and parenthood, and verbalizing readiness to assume parental responsibilities are all developmental tasks of the young adult according to Erikson's theory.

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.
