Nursing Elites

1. A healthcare professional is preparing to care for a client with a potassium deficit. The healthcare professional reviews the client's record and determines that the client was at risk for developing the potassium deficit because the client:

• A. Has renal failure.
• B. Requires nasogastric suction.
• C. Has a history of Addison's disease.
• D. Is taking a potassium-sparing diuretic.

Correct answer: B

Rationale: Nasogastric suction can lead to significant potassium loss due to the continuous drainage of gastric contents, increasing the risk of a potassium deficit. Choices A, C, and D do not directly result in the significant loss of potassium. Renal failure may lead to potassium retention rather than a deficit. Addison's disease is associated with adrenal insufficiency, not potassium depletion. Potassium-sparing diuretics, as the name suggests, typically help retain potassium rather than cause a deficit.

2. 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.

3. A client with DM asks a nurse why it is necessary to rotate injection sites when using an insulin pen. The nurse's best response would be:

• A. To prevent scar tissue from forming under the skin.
• B. To make the injections less painful.
• C. To help the insulin absorb better.
• D. To keep the skin looking healthy.

Correct answer: C

Rationale: The correct answer is C: "To help the insulin absorb better." Rotating injection sites is important as it helps to ensure better insulin absorption and reduces the risk of developing lipodystrophy. Option A is incorrect as rotating sites primarily aims to optimize insulin absorption, not prevent scar tissue. Option B is inaccurate because rotating injection sites does not necessarily make the injections less painful. Option D is incorrect as the primary reason for rotating injection sites is not related to the aesthetics of the skin but rather to enhance insulin absorption and prevent complications.

4. A client with hyperaldosteronism is at risk for which of the following electrolyte imbalances?

• A. Hyperkalemia
• B. Hyponatremia
• C. Hypokalemia
• D. Hypercalcemia

Correct answer: C

Rationale: In hyperaldosteronism, there is an excessive secretion of aldosterone, a hormone that promotes potassium excretion in the kidneys. This leads to low potassium levels in the blood, known as hypokalemia. Therefore, the correct answer is hypokalemia (Choice C). Hyperkalemia (Choice A) is the opposite condition, where there is high potassium levels in the blood and is not typically associated with hyperaldosteronism. Hyponatremia (Choice B) is a low sodium level, which is not directly related to aldosterone function. Hypercalcemia (Choice D) is an elevated calcium level and is not typically a direct result of hyperaldosteronism.

5. A client with type 2 diabetes mellitus is prescribed metformin. The nurse should monitor the client for which of the following potential side effects?

• A. Lactic acidosis
• B. Hypokalemia
• C. Hyperglycemia
• D. Weight gain

Correct answer: A

Rationale: The correct answer is A, lactic acidosis. Metformin, a common medication for type 2 diabetes mellitus, can lead to lactic acidosis, particularly in individuals with renal impairment or predisposing factors. Monitoring for signs of lactic acidosis, such as muscle pain, weakness, trouble breathing, dizziness, and slow or uneven heart rate, is crucial to prevent serious complications. Choices B, C, and D are incorrect as metformin does not typically cause hypokalemia, hyperglycemia, or weight gain as its primary side effects.
