Correct Answer: C

Rationale: The correct instruction is choice C: 'You may not be able to use desmopressin nasally if you have nasal discharge or blockage.' Nasal congestion or blockage can interfere with the absorption of nasally administered desmopressin. Choices A, B, and D are incorrect. Choice A is unnecessary as the temperature of the suspension does not impact desmopressin administration. Choice B is incorrect as wearing a medical identification bracelet is essential for individuals with diabetes insipidus to alert healthcare providers in case of emergencies. Choice D is incorrect as monitoring fluid intake and output is crucial when taking desmopressin to ensure proper hydration and medication effectiveness.

Correct Answer: B

Rationale: Monitoring blood glucose levels frequently is crucial for preventing complications in diabetes. By keeping a close eye on blood glucose levels, healthcare providers can intervene in a timely manner if levels are out of range, thus reducing the risk of long-term complications such as nerve damage, kidney disease, and vision problems. Choices A, C, and D are incorrect because while monitoring blood glucose levels may indirectly contribute to adjusting insulin doses, identifying the best diet, and reducing the need for medications, the primary purpose is to prevent complications through timely interventions.

Correct Answer: A

Rationale: The priority nursing diagnosis for a client with Addison's disease is 'Fluid volume deficit.' Addison's disease is characterized by adrenal insufficiency, resulting in decreased aldosterone production. Aldosterone plays a key role in sodium and water retention in the body. With its deficiency, there is an increased risk of dehydration and electrolyte imbalance, leading to fluid volume deficit. While infection risk, nutrition issues, and body image disturbances are also important considerations for holistic care, addressing the fluid volume deficit takes precedence due to the immediate physiological impact on the client's health and well-being.

Correct Answer: D

Rationale: An adrenal adenoma is the most common cause of primary hyperaldosteronism. Hyperaldosteronism is typically caused by an adrenal adenoma, a benign tumor in the adrenal gland that leads to excessive aldosterone production. Excessive sodium intake (Choice A) does not directly cause hyperaldosteronism. Pituitary adenoma (Choice B) is associated with conditions like Cushing's disease, not hyperaldosteronism. Deficient potassium intake (Choice C) can lead to hypokalemia but is not a common cause of hyperaldosteronism.

Correct Answer: A

Rationale: Clients with Addison's disease should be educated to double their corticosteroid dosage during periods of stress. This is crucial to prevent adrenal crisis, as stress can increase the body's demand for cortisol. Skipping doses when feeling well can lead to an adrenal crisis if stress occurs suddenly. Decreasing fluid intake can exacerbate dehydration and electrolyte imbalances, which are already concerns in Addison's disease. Avoiding physical activity during stressful times is not the most appropriate advice; moderate physical activity can be beneficial, as long as the client is adequately managing their corticosteroid regimen.
