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. The client with hyperthyroidism is receiving propylthiouracil (PTU). The nurse should monitor for which of the following potential side effects?

A. Leukopenia
B. Hyperglycemia
C. Hypertension
D. Weight gain

Correct answer: A

Rationale: The correct answer is A: Leukopenia. Propylthiouracil can lead to bone marrow suppression, resulting in leukopenia. Monitoring white blood cell counts is crucial to detect this potential side effect early. Choice B, hyperglycemia, is not typically associated with propylthiouracil use. Choice C, hypertension, is not a common side effect of propylthiouracil. Choice D, weight gain, is also not a typical side effect of propylthiouracil therapy.

3. The client has received IV solutions for three (3) days through a 20-gauge IV catheter placed in the left cephalic vein. On morning rounds, the nurse notes the IV site is tender to palpation and a red streak has formed. Which action should the nurse implement first?

A. Start a new IV in the right hand.
B. Discontinue the intravenous line.
C. Complete an incident record.
D. Place a warm washcloth over the site.

Correct answer: B

Rationale: The first action should be to discontinue the intravenous line to prevent further complications such as infection or thrombophlebitis. Starting a new IV in the right hand is not the priority as addressing the current issue is important. Completing an incident record can be done after addressing the immediate concern of the IV site. Placing a warm washcloth over the site does not address the red streak and tenderness, which may indicate an infection that requires discontinuation of the IV line.

4. A male client with a tentative diagnosis of hyperosmolar hyperglycemic nonketotic syndrome (HHNS) has a history of type 2 diabetes that is being controlled with an oral diabetic agent, tolazamide (Tolinase). Which of the following is the most important laboratory test for confirming this disorder?

A. Serum potassium level
B. Serum sodium level
C. Arterial blood gas (ABG) values
D. Serum osmolarity

Correct answer: D

Rationale: Serum osmolarity is the most important laboratory test for confirming hyperosmolar hyperglycemic nonketotic syndrome (HHNS). HHNS is characterized by severe hyperglycemia and dehydration without ketoacidosis. Elevated serum osmolarity indicates increased solute concentration in the blood, which is a hallmark of HHNS. Serum potassium level (Choice A) is important in conditions like diabetic ketoacidosis rather than HHNS. Serum sodium level (Choice B) may be affected in HHNS but is not the primary test for confirming the disorder. Arterial blood gas (ABG) values (Choice C) are more useful in assessing acid-base status, which is not the primary concern in HHNS.

5. A client with type 1 diabetes mellitus is admitted to the hospital with diabetic ketoacidosis (DKA). Which of the following interventions should the nurse implement first?

A. Administer intravenous insulin
B. Start an intravenous line and infuse normal saline
C. Monitor serum potassium levels
D. Obtain an arterial blood gas (ABG)

Correct answer: B

Rationale: The correct first intervention in the treatment of a client with diabetic ketoacidosis (DKA) is to start an intravenous line and infuse normal saline. This is essential for fluid resuscitation to restore intravascular volume and improve perfusion. Administering intravenous insulin can lead to further potassium depletion without first addressing dehydration and electrolyte imbalances. Monitoring serum potassium levels is important but should follow fluid resuscitation to avoid life-threatening hypokalemia. Obtaining an arterial blood gas (ABG) is necessary to assess the acid-base status but is not the initial priority when managing DKA.
