Correct Answer: A

Rationale: The correct answer is A: 25 g/day, initially. In this scenario, the client with Hashimoto's thyroiditis and a history of cardiac issues requires a cautious approach due to the risk of exacerbating cardiac conditions with thyroid hormone replacement. Starting with a low dose of 25 µg/day allows for careful monitoring of the client's response and prevents potential adverse effects on the cardiovascular system. Summary: B: Delayed until after thyroid surgery - Not appropriate as the client requires thyroid replacement therapy for Hashimoto's thyroiditis. C: 100 µg/day, initially - Too high of an initial dose and may lead to adverse cardiovascular effects. D: Initiated before thyroid surgery - Not relevant to the client's situation as there is no indication for thyroid surgery mentioned in the question.

Correct Answer: A

Rationale: The correct answer is A: Adrenal cortex. Primary hyperaldosteronism is a condition where the adrenal cortex produces too much aldosterone hormone, leading to hypertension. The adrenal medulla secretes adrenaline and noradrenaline, not aldosterone, making option B incorrect. The pancreas secretes insulin and glucagon, not aldosterone, making option C incorrect. Option D is incorrect because the adrenal cortex is responsible for aldosterone secretion in primary hyperaldosteronism.

Correct Answer: A

Rationale: Rationale: 1. Digital rectal exam (DRE) and PSA test are recommended by major health organizations for prostate cancer screening in men over 50. 2. DRE helps detect abnormalities in the prostate, while PSA test measures the levels of a protein produced by the prostate gland. 3. Prostate cancer can be asymptomatic in its early stages, so regular screening is crucial for early detection and treatment. 4. Transrectal ultrasound is not a primary screening method for prostate cancer. 5. Testicular self-exams are for detecting testicular cancer, not prostate cancer. 6. CBC, BUN, and creatinine levels are not specific tests for prostate cancer screening.

Correct Answer: C

Rationale: The correct answer is C: "You may feel a burning sensation when the dye is injected." This is important to include in preprocedure teaching for carotid angiography because it prepares the patient for a common sensation they may experience during the procedure. Providing this information helps manage expectations and reduce anxiety. Choice A is incorrect because carotid angiography is typically done with the patient awake. Choice B is incorrect as carotid angiography usually takes around 30-60 minutes. Choice D is incorrect because there can be complications associated with carotid angiography, such as allergic reactions or damage to blood vessels.

Correct Answer: B

Rationale: The correct answer is B: To carry out the plan of care. In the nursing process, implementation is the phase where nurses put the established care plan into action by delivering the interventions outlined to meet the client's needs. This step is crucial as it ensures that the care plan is executed effectively and efficiently. Establishing priorities (A) is done during the planning phase, identifying client outcomes (C) is part of the evaluation phase, and validating nursing diagnoses (D) is typically done during the assessment phase, not implementation.
