Nursing Elites

1. When caring for a male client with diabetes insipidus, what does Nurse Juliet expect to administer?

• A. Vasopressin (Pitressin Synthetic)
• B. Furosemide (Lasix)
• C. Regular insulin
• D. 10% dextrose

Correct answer: A

Rationale: The correct answer is A: Vasopressin (Pitressin Synthetic). Vasopressin is the treatment of choice for diabetes insipidus as it replaces the deficient antidiuretic hormone. Furosemide (Lasix) (choice B) is a diuretic and would exacerbate fluid loss, making it inappropriate for diabetes insipidus. Regular insulin (choice C) is used for diabetes mellitus, not diabetes insipidus, which involves water balance rather than glucose regulation. 10% dextrose (choice D) is used to treat hypoglycemia, not diabetes insipidus.

2. What is the lowest fasting plasma glucose level suggestive of a diagnosis of DM?

• A. 90 mg/dl.
• B. 115 mg/dl.
• C. 126 mg/dl.
• D. 180 mg/dl.

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.

3. 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.

4. Nurse Perry is caring for a female client with type 1 diabetes mellitus who exhibits confusion, light-headedness, and aberrant behavior. The client is still conscious. The nurse should first administer:

• A. I.M. or subcutaneous glucagon.
• B. I.V. bolus of dextrose 50%.
• C. 15 to 20 g of a fast-acting carbohydrate such as orange juice.
• D. 10 U of fast-acting insulin.

Correct answer: C

Rationale: For a conscious client with hypoglycemia, the initial treatment should involve administering 15 to 20 g of a fast-acting carbohydrate, such as orange juice. This helps rapidly raise the client's blood glucose levels. Choices A and D are incorrect as administering glucagon or fast-acting insulin is not the first-line treatment for hypoglycemia in a conscious client. Choice B, an I.V. bolus of dextrose 50%, is a more invasive and aggressive intervention that is not typically indicated for a conscious client with hypoglycemia.

5. The nurse is caring for a client with DM who is experiencing ketoacidosis. The nurse should prioritize which action?

• A. Administering insulin intravenously.
• B. Giving the client sips of water.
• C. Monitoring the client's urine output.
• D. Applying a heating pad to the client's abdomen.

Correct answer: A

Rationale: Administering insulin intravenously is the priority action for managing diabetic ketoacidosis. Insulin helps lower blood glucose levels and halts the production of ketones, addressing the underlying cause of ketoacidosis. Giving sips of water (Choice B) may be necessary for hydration, but it does not address the immediate life-threatening issue of ketoacidosis. Monitoring urine output (Choice C) is important for assessing renal function but is not the priority over administering insulin. Applying a heating pad (Choice D) is not indicated and can potentially worsen the condition in ketoacidosis.
