Correct Answer: C

Rationale: In myxedema coma, the priority intervention is to administer levothyroxine intravenously. Myxedema coma is a severe form of hypothyroidism, and intravenous levothyroxine is crucial to rapidly replace deficient thyroid hormones. Administering intravenous fluids (choice A) may be necessary, but levothyroxine takes precedence. Providing a warming blanket (choice B) can help maintain the client's body temperature, but it does not address the underlying thyroid hormone deficiency. Placing the client in Trendelenburg position (choice D) is not indicated and can potentially worsen the client's condition.

Correct Answer: A

Rationale: Muscle weakness is a classic manifestation of hyperkalemia, an elevated level of potassium in the blood. After an adrenalectomy, where one adrenal gland is removed, there may be a risk of hyperkalemia due to altered hormone regulation. Tremors (Choice B) are not typically associated with hyperkalemia but may be seen in conditions like hypocalcemia. Diaphoresis (Choice C) and constipation (Choice D) are not specific indicators of hyperkalemia. Diaphoresis is excessive sweating and constipation is a common gastrointestinal issue, neither directly related to potassium imbalances.

Correct Answer: C

Rationale: A fasting plasma glucose level of 126 mg/dl or higher is diagnostic of diabetes mellitus. Choice A (90 mg/dl) is too low to indicate diabetes. Choice B (115 mg/dl) is also below the diagnostic threshold for diabetes. Choice D (180 mg/dl) is above the diagnostic threshold and would indicate uncontrolled diabetes, not the lowest level suggestive of a diagnosis.

Correct Answer: A

Rationale: The correct answer is 'Apples.' Apples are the lowest in potassium among the given options. Carrots, spinach, and avocados are all higher in potassium content compared to apples. Carrots and spinach are vegetables known to have a moderate amount of potassium. Avocados, on the other hand, are a high-potassium fruit and would not be the lowest in potassium among the choices provided.

Correct Answer: C

Rationale: Confidentiality is the ethical principle involved in protecting a patient's privacy and ensuring that personal information is not shared inappropriately. Fidelity refers to being faithful to commitments and keeping promises, not directly related to privacy and confidentiality. Beneficence involves doing good for the patient, and justice pertains to fairness and equal treatment, but they are not directly related to protecting privacy and confidentiality.
