Correct Answer: B

Rationale: Inviting individuals in recovery to share their stories is the most effective strategy for educating adolescents about the dangers of substance abuse. Personal stories have a significant impact as they provide real-life examples of the consequences of substance abuse, making the information more relatable and emotionally engaging. This approach can evoke empathy, create a deeper understanding of the risks involved, and potentially deter adolescents from experimenting with substances. Showing videos of the effects of substance abuse (choice A) may be impactful, but personal narratives often have a stronger emotional connection. Providing statistical data (choice C) may not resonate as strongly with adolescents as personal stories. Distributing brochures (choice D) is informative but may not have the same emotional impact and engagement as hearing firsthand experiences.

Correct Answer: C

Rationale: The correct instruction for a client newly diagnosed with hypothyroidism is to take the medication on an empty stomach. This is important because taking levothyroxine on an empty stomach ensures better absorption of the medication. Choice A, taking levothyroxine at bedtime, is incorrect as it does not promote optimal absorption. Choice B, increasing fiber intake to prevent constipation, is important but not the priority when it comes to medication administration. Choice D, taking a double dose if a dose is missed, is dangerous and should never be advised as it can lead to overdose and serious side effects.

Correct Answer: A

Rationale: The correct answer is A: Hemoglobin of 12 g/dL. Erythropoietin therapy stimulates red blood cell production, leading to an increase in hemoglobin levels. A hemoglobin level of 12 g/dL indicates that the therapy is effective in managing anemia associated with chronic kidney disease. Choice B, a reticulocyte count of 1%, is not a direct indicator of the effectiveness of erythropoietin therapy. Choice C, a blood pressure of 130/80 mm Hg, is important to monitor in clients with chronic kidney disease but does not specifically indicate the effectiveness of erythropoietin therapy. Choice D, a serum ferritin level of 100 ng/mL, is related to iron stores in the body and may be monitored during erythropoietin therapy but does not directly reflect the therapy's effectiveness in increasing red blood cell production.

Correct Answer: A

Rationale: The 45-year-old father who smokes and has high cholesterol is at a higher risk for cardiovascular disease due to multiple risk factors. Smoking and high cholesterol are significant contributors to the development of cardiovascular issues. Prioritizing his evaluation and intervention is crucial to address these modifiable risk factors. The other family members, though they may have risk factors as well, do not present with the same level of immediate risk based on the information provided.

Correct Answer: A

Rationale: Recognizing signs of infant dehydration is crucial for ensuring the health and well-being of infants. Dehydration can be life-threatening for infants if not addressed promptly. Proper diaper changing techniques, while important for hygiene, can be learned incrementally. The immunization schedule and breastfeeding positions are also essential topics, but identifying signs of dehydration takes precedence as it requires immediate attention to prevent serious complications.
