Correct Answer: A

Rationale: The correct answer is A: Muscle weakness. Hypokalemia is characterized by low potassium levels in the blood, which can lead to muscle weakness. This occurs because potassium is essential for proper muscle function, and a deficiency can impair muscle strength. Nausea (choice B) is not a typical finding associated with hypokalemia. Tingling sensation (choice C) is more commonly linked to issues like nerve damage or poor blood circulation, rather than hypokalemia. Increased thirst (choice D) is not a direct symptom of hypokalemia; it is more commonly seen in conditions like diabetes or dehydration.

Correct Answer: C

Rationale: Dry skin is a common manifestation of hypothyroidism due to decreased thyroid hormone levels, leading to reduced sweating and oil production. Weight gain may occur due to a slowed metabolism, not diarrhea, as hypothyroidism is more commonly associated with constipation. Hair loss is typically associated with hyperthyroidism, not hypothyroidism.

Correct Answer: A

Rationale: The correct answer is to administer potassium-wasting diuretics. Hyperkalemia, which is high potassium levels, is managed by promoting the excretion of potassium from the body. Potassium-wasting diuretics help the kidneys eliminate excess potassium. Encouraging a low-potassium diet (choice B) is important for long-term management but not the immediate intervention for hyperkalemia. Administering potassium supplements (choice C) would worsen the condition by further increasing potassium levels. Administering IV fluids (choice D) may help with hydration but does not directly address the high potassium levels characteristic of hyperkalemia.

Correct Answer: D

Rationale: In resolving ethical dilemmas, it is essential to identify possible solutions to address the client care dilemma effectively. Option A, 'Ensure client autonomy only,' is not comprehensive enough to resolve complex ethical issues. Option B, 'Consider only medical benefits,' overlooks other important factors beyond medical benefits that are involved in ethical decision-making. Option C, 'Ensure clear communication among the health care team,' is important but may not be sufficient on its own to resolve the ethical dilemma. Therefore, the most effective strategy among the given options is to identify possible solutions to navigate through the ethical dilemma.

Correct Answer: B

Rationale: Tingling in the fingers is a classic sign of hypocalcemia. Following a thyroidectomy, hypocalcemia can occur due to damage to the parathyroid glands, which regulate calcium levels in the body. Nausea, numbness in the toes, and sweating are not specific signs of hypocalcemia. Numbness and tingling usually start in the hands and feet due to their increased nerve sensitivity to low calcium levels.
