Correct Answer: A

Rationale: Setting up vaccination clinics in accessible locations is the most effective intervention to improve vaccination rates. This intervention ensures easy access to vaccination services for community members, removing barriers such as transportation or time constraints. Distributing flyers (Choice B) may increase awareness but may not directly address access issues. Offering incentives (Choice C) might temporarily boost vaccination rates but may not lead to sustained behavior change. Partnering with local businesses (Choice D) could be beneficial for promotion but may not directly impact vaccination accessibility.

Correct Answer: D

Rationale: After hemodialysis, muscle cramps can indicate an electrolyte imbalance, such as low potassium or magnesium levels, which requires immediate intervention to prevent potential complications like cardiac arrhythmias. Weight gain of 1 pound, dizziness, and fatigue are common post-hemodialysis symptoms that may not necessarily require immediate intervention unless they are severe or persisting.

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, 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: 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.
