Nursing Elites

1. A client with diabetes mellitus is experiencing symptoms of hypoglycemia. The nurse should instruct the client to do which of the following?

• A. Eat a high-protein snack
• B. Consume 15 grams of simple carbohydrates
• C. Drink a glass of water
• D. Administer an extra dose of insulin

Correct answer: B

Rationale: Consuming 15 grams of simple carbohydrates is the recommended treatment for mild hypoglycemia to quickly raise blood sugar levels. Simple carbohydrates are rapidly absorbed and provide a quick source of glucose to combat low blood sugar. Eating a high-protein snack (Choice A) would delay the rise in blood sugar as proteins take longer to be broken down. Drinking water (Choice C) does not directly address the low blood sugar levels associated with hypoglycemia. Administering an extra dose of insulin (Choice D) would further lower blood sugar levels, worsening the hypoglycemic state.

2. Nurse Wayne is aware that a positive Chvostek's sign indicates:

• A. Hypocalcemia
• B. Hyponatremia
• C. Hypokalemia
• D. Hypermagnesemia

Correct answer: A

Rationale: A positive Chvostek's sign indicates hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching due to increased neuromuscular irritability from low calcium levels. Hyponatremia (Choice B) is characterized by low sodium levels, but it does not present with Chvostek's sign. Hypokalemia (Choice C) is low potassium levels, and hypermagnesemia (Choice D) is high magnesium levels, neither of which are associated with Chvostek's sign.

3. When teaching a male client diagnosed with type 1 diabetes mellitus how diet and exercise affect insulin requirements, Nurse Joy should include which guideline?

• A. You'll need more insulin when you exercise or increase your food intake.
• B. You'll need less insulin when you exercise or reduce your food intake.
• C. You'll need less insulin when you increase your food intake.
• D. You'll need more insulin when you exercise or decrease your food intake.

Correct answer: B

Rationale: When a person with type 1 diabetes exercises, it typically lowers blood glucose levels. As a result, insulin needs are reduced when exercise or food intake is decreased. Choice A is incorrect because more insulin is not typically needed when exercise or food intake is increased. Choice C is incorrect because increasing food intake would generally require more insulin to cover the additional glucose from the food. Choice D is incorrect as decreasing food intake usually leads to a lower need for insulin.

4. A female client with a history of pheochromocytoma is admitted to the hospital in an acute hypertensive crisis. To reverse the hypertensive crisis caused by pheochromocytoma, nurse Lyka expects to administer:

• A. Phentolamine (Regitine)
• B. Methyldopa (Aldomet)
• C. Mannitol (Osmitrol)
• D. Felodipine (Plendil)

Correct answer: A

Rationale: In a hypertensive crisis due to pheochromocytoma, the appropriate medication to administer is Phentolamine (Regitine), an alpha-adrenergic blocker. Phentolamine acts quickly to block the effects of excess catecholamines that are released in pheochromocytoma, helping to rapidly lower blood pressure. Methyldopa (Aldomet) is an alpha-2 adrenergic agonist used for chronic hypertension, not for acute crises like pheochromocytoma. Mannitol (Osmitrol) is an osmotic diuretic used to reduce intracranial pressure and treat cerebral edema, not indicated for hypertensive crises. Felodipine (Plendil) is a calcium channel blocker used for chronic management of hypertension, not for acute hypertensive crises like those seen in pheochromocytoma.

5. A client with hypoparathyroidism is at risk for which of the following complications?

• A. Hypercalcemia
• B. Hypocalcemia
• C. Hyperkalemia
• D. Hypernatremia

Correct answer: B

Rationale: Hypoparathyroidism is characterized by decreased levels of parathyroid hormone, leading to reduced calcium levels in the blood, which results in hypocalcemia. Therefore, the correct answer is B. Choices A, C, and D are incorrect because hypoparathyroidism does not typically lead to hypercalcemia, hyperkalemia, or hypernatremia. Hypercalcemia is more commonly associated with hyperparathyroidism, where there is excess secretion of parathyroid hormone.
