1. What is the most common cause of hyperaldosteronism?

• A. Excessive sodium intake
• B. A pituitary adenoma
• C. Deficient potassium intake
• D. An adrenal adenoma

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.

2. Following a unilateral adrenalectomy, Nurse Betty would assess for hyperkalemia indicated by which of the following signs?

• A. Muscle weakness
• B. Tremors
• C. Diaphoresis
• D. Constipation

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.

3. What clinical feature distinguishes a hypoglycemic reaction from a ketoacidosis reaction?

• A. Blurred vision.
• B. Diaphoresis.
• C. Nausea.
• D. Weakness.

Correct answer: B

Rationale: Diaphoresis is the correct answer because it is more characteristic of hypoglycemia. Hypoglycemia typically presents with symptoms such as diaphoresis (excessive sweating), palpitations, tremors, and anxiety. On the other hand, ketoacidosis is associated with symptoms such as fruity breath, deep and labored breathing (Kussmaul respirations), nausea, vomiting, and abdominal pain. Blurred vision can occur in both hypoglycemia and ketoacidosis due to metabolic disturbances affecting the eyes. Weakness is a nonspecific symptom that can be present in both conditions, making it less helpful in distinguishing between the two.

4. A client with diabetes mellitus is experiencing symptoms of hypoglycemia. Which of the following is the nurse's priority action?

• A. Administer glucagon
• B. Check the client's blood glucose level
• C. Give the client a snack
• D. Notify the healthcare provider

Correct answer: B

Rationale: The correct answer is to check the client's blood glucose level. This is the priority action to confirm hypoglycemia before implementing further interventions. Administering glucagon (Choice A) may be necessary in severe cases of hypoglycemia, but confirming the low blood glucose level is crucial before administering any treatment. Giving the client a snack (Choice C) can help raise blood sugar levels but should come after confirming the hypoglycemia. Notifying the healthcare provider (Choice D) is important, but the immediate priority is to assess and address the hypoglycemia.

5. Which instruction about insulin administration should Nurse Kate give to a client?

• A. Always follow the same order when drawing up different insulins into the syringe.
• B. Shake the vials before withdrawing the insulin.
• C. Store unopened vials of insulin in the refrigerator at recommended temperatures.
• D. Discard the intermediate-acting insulin if it appears cloudy.

Correct answer: A

Rationale: The correct answer is A. Consistently following the same order when drawing up different insulins helps to prevent medication errors. Option B is incorrect because shaking insulin vials could cause bubbles to form, leading to inaccurate dosing. Option C is incorrect as insulin should be stored in the refrigerator, not the freezer, to maintain its effectiveness. Option D is incorrect because cloudy appearance in intermediate-acting insulin may indicate the presence of insulin crystals, which can affect its potency, but this does not necessarily mean it should be discarded without consulting a healthcare provider.
