Correct Answer: D

Rationale: Cyanosis is a late sign of hypoxemia and indicates severe oxygen deprivation, necessitating immediate intervention in a client with a suspected pulmonary embolism. Chest pain, shortness of breath, and tachycardia are also concerning symptoms in pulmonary embolism; however, cyanosis signifies critical oxygen deficiency and warrants urgent attention to prevent further complications.

Correct Answer: D

Rationale: Conducting a community needs assessment is the most appropriate initial intervention when addressing domestic violence in the community. This step helps the nurse identify existing resources, gaps, and specific needs of the community related to domestic violence. By understanding the community's needs through a needs assessment, the nurse can tailor subsequent interventions effectively. Option A, establishing a support group, may be beneficial later but should not be the first step. Developing educational materials (Option B) and partnering with law enforcement (Option C) are important strategies; however, without understanding the community's specific needs through a needs assessment, the interventions may not be as targeted or effective.

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: 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: C

Rationale: Involving adolescents in meal planning and preparation is a more effective strategy as it actively engages them in the learning process. This approach allows adolescents to have hands-on experience, make informed choices, and develop a sense of ownership over their dietary decisions. Lecturing about dangers or showing documentaries may not be as engaging or interactive, making it less likely for adolescents to retain and apply the information provided. Distributing pamphlets can be informative but lacks the interactive and experiential aspect that involving them in meal planning and preparation offers.
