Correct Answer: C

Rationale: The most important information for the nurse to obtain before implementing a community health program targeting teenage smoking is the prevalence and patterns of smoking among teenagers. Understanding this data is crucial to tailor the program to the specific needs and behaviors of the target group, ensuring it addresses the root causes effectively. Choices A, B, and D are unrelated to the specific needs of the target group and do not provide essential information for designing an effective smoking cessation program for teenagers.

Correct Answer: D

Rationale: The correct answer is D: explain that the client should stay home for the next few days. Viral conjunctivitis is highly contagious, and the client should avoid close contact with others until it resolves. Returning to work while still contagious can lead to the spread of the infection to coworkers and customers. Choice A is incorrect because wearing a face mask may not provide sufficient protection against spreading the virus in a close work environment. Choice B is irrelevant to the situation as the focus should be on the client's health and preventing the spread of the infection. Choice C is also unrelated to the management of viral conjunctivitis and does not address the contagious nature of the condition.

Correct Answer: A

Rationale: The correct answer is A, Graves' disease. The symptoms described in the client are classic manifestations of hyperthyroidism, which is commonly caused by Graves' disease, an autoimmune condition affecting the thyroid. Weight loss, racing heart rate, difficulty sleeping, moist skin with fine hair, prominent eyes, lid retraction, and a staring expression are all indicative of hyperthyroidism. Choice B, Cushing's syndrome, is characterized by weight gain, hypertension, and a rounded face due to excess cortisol. Choice C, Addison's disease, presents with symptoms such as weight loss, fatigue, and hyperpigmentation due to adrenal insufficiency. Choice D, hypothyroidism, typically features symptoms opposite to those described in the client, such as weight gain, bradycardia, and dry skin.

Correct Answer: B

Rationale: Inviting former smokers to share their experiences is the most effective strategy because personal stories can have a powerful impact on adolescents and motivate them to avoid smoking. This approach makes the consequences of smoking more relatable and real, potentially influencing behavior change. Showing graphic images may be too harsh and could lead to desensitization or avoidance of the issue. Providing statistical data may not resonate as strongly with adolescents as personal stories. Distributing pamphlets, while informative, may not have the same emotional impact as hearing real-life experiences.

Correct Answer: C

Rationale: The correct answer is C. Insulin should not be stored in the refrigerator at all times; it should be kept at room temperature when in use to avoid irritation at the injection site. Storing insulin in the refrigerator can cause it to thicken and may lead to discomfort upon injection. Choices A and D are correct statements as injecting insulin into the abdomen for faster absorption and rotating injection sites to prevent lipodystrophy are appropriate insulin administration techniques. Therefore, the client does not need further teaching on these aspects.
