Correct Answer: A

Rationale: The correct answer is A: 'Avoid foods high in iodine.' Clients with hyperthyroidism should avoid foods high in iodine to prevent exacerbation of their condition. Iodine is an essential component in thyroid hormone production, and excessive iodine intake can worsen hyperthyroidism symptoms. Taking medication with meals (B) can interfere with the absorption of certain thyroid medications. Monitoring weight daily (C) is more relevant for conditions that may lead to weight changes like hypothyroidism. Decreasing fluid intake (D) is not a standard recommendation for hyperthyroidism unless specifically indicated by the healthcare provider.

Correct Answer: C

Rationale: To evaluate the effectiveness of atorvastatin (Lipitor), the nurse should monitor liver function tests (LFTs) (C) because this medication can impact liver function. Complete blood count (CBC) (A), serum potassium level (B), and serum cholesterol level (D) are not directly indicative of the medication's effectiveness in managing coronary artery disease.

Correct Answer: C

Rationale: An elevated AST level following chest pain and shortness of breath is suggestive of myocardial infarction. AST is released from damaged heart muscle cells during a heart attack, indicating cardiac involvement. This enzyme is not specific to liver disease, gallbladder disease, or skeletal muscle injury in this clinical context.

Correct Answer: A

Rationale: To calculate the mL to administer, divide the ordered dose (3 mg) by the concentration (4 mg/mL). 3 mg · 4 mg/mL = 0.75 mL. Rounding to the nearest tenth, the correct dose to administer is 0.8 mL.

Correct Answer: C

Rationale: The Good Samaritan Act shields healthcare professionals who act in good faith and offer reasonable care from malpractice claims, irrespective of the client's outcome. In this scenario, the nurse stopping to render aid at the accident scene and applying pressure to the bleeding groin wound would likely be covered by the Good Samaritan Act, protecting the nurse from legal repercussions related to the subsequent leg amputation.
