Correct Answer: B

Rationale: Clinical manifestations of type 1 diabetes mellitus include hypoglycemia, ketonuria, and polyphagia. Hyponatremia is not typically associated with type 1 diabetes mellitus; it is more commonly linked with other conditions such as syndrome of inappropriate antidiuretic hormone secretion (SIADH) or heart failure. Therefore, the correct answer is B: Hyponatremia.

Correct Answer: C

Rationale: A DNR order is typically written after the healthcare provider has discussed the implications with the patient and their family. This ensures that the patient and family are fully informed before making such a critical decision. Choice A is incorrect because pronouncing clinical death is a medical determination, not directly related to DNR orders. Choice B is incorrect because while physicians commonly write DNR orders, the discussion with the patient and family is crucial. Choice D is incorrect because a DNR order does not require a court decision; it is a decision made in collaboration with the healthcare team and the patient or family.

Correct Answer: B

Rationale: Primary aldosteronism involves the overproduction of aldosterone by the adrenal glands. Aldosterone increases potassium excretion, leading to hypokalemia. Therefore, in primary aldosteronism, the nurse would expect to find hypokalemia, not hyperkalemia (choice A), hyponatremia (choice C), or hypercalcemia (choice D).

Correct Answer: C

Rationale: Propranolol is a beta-blocker that works by blocking the effects of adrenaline, which helps to reduce symptoms such as tachycardia (fast heart rate) and anxiety in individuals with hyperthyroidism. Choices A and B are incorrect because propranolol does not affect thyroid hormone production; it only addresses symptoms. Choice D is incorrect because propranolol does not prevent weight loss associated with hyperthyroidism.

Correct Answer: C

Rationale: Exercising at least five times a week is recommended to meet the goals of planned exercise for diabetic clients. This frequency helps in managing blood sugar levels effectively and improving overall health. Exercising once a week (Choice A) may not provide sufficient benefits or consistency required for diabetic clients. Exercising three times a week (Choice B) is better but may still fall short of the recommended frequency for optimal outcomes. Exercising every day (Choice D) may lead to burnout or overtraining if not properly balanced with rest days, which could be counterproductive for diabetic clients.
