Nursing Elites

1. A client with DM is experiencing symptoms of hypoglycemia. Which action should the nurse take first?

• A. Give the client a glass of orange juice.
• B. Administer insulin as ordered.
• C. Check the client's blood glucose level.
• D. Notify the healthcare provider.

Correct answer: C

Rationale: The correct first action when a client with DM is experiencing symptoms of hypoglycemia is to check the client's blood glucose level. This step is crucial to confirm hypoglycemia before initiating any treatment. Giving the client orange juice (Choice A) is a common intervention for treating hypoglycemia, but it should not be done before confirming the blood glucose level. Administering insulin (Choice B) is not appropriate for hypoglycemia as it would further decrease the blood glucose levels. Notifying the healthcare provider (Choice D) can be important, but the immediate priority is to assess the blood glucose level to guide treatment.

2. A client with type 1 diabetes mellitus presents with nausea, vomiting, and abdominal pain. The nurse suspects diabetic ketoacidosis (DKA). Which of the following lab findings would confirm this diagnosis?

• A. Serum glucose of 180 mg/dL
• B. Serum bicarbonate of 22 mEq/L
• C. Blood pH of 7.25
• D. Urine specific gravity of 1.020

Correct answer: C

Rationale: A blood pH of 7.25 is a critical finding in diabetic ketoacidosis (DKA) as it indicates metabolic acidosis, which is a hallmark of this condition. In DKA, there is an accumulation of ketones in the blood, leading to increased acidity. The serum glucose level is typically elevated in DKA, often exceeding 250 mg/dL. A serum bicarbonate level less than 18 mEq/L is usually seen in DKA due to the metabolic acidosis. Urine specific gravity is not a specific indicator for DKA and may vary depending on the individual's hydration status. Therefore, the correct lab finding that confirms DKA in this scenario is a blood pH of 7.25.

3. A client with hyperthyroidism is prescribed methimazole. The nurse should instruct the client that the purpose of this medication is to:

• A. Decrease thyroid hormone production
• B. Increase thyroid hormone production
• C. Suppress the immune system
• D. Prevent thyroid storm

Correct answer: A

Rationale: The correct answer is A: Decrease thyroid hormone production. Methimazole works by inhibiting the synthesis of thyroid hormones, specifically by blocking the enzyme responsible for this process. By reducing the production of thyroid hormones, methimazole helps to normalize the elevated levels seen in hyperthyroidism. Choices B, C, and D are incorrect. Choice B, 'Increase thyroid hormone production,' is inaccurate as methimazole actually decreases thyroid hormone production. Choice C, 'Suppress the immune system,' is unrelated to the mechanism of action of methimazole. Choice D, 'Prevent thyroid storm,' is not the primary purpose of methimazole; while it may help prevent worsening of hyperthyroidism, its main action is to reduce thyroid hormone levels.

4. 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.

5. A client with hypothyroidism is prescribed levothyroxine. The nurse should teach the client to take this medication:

• A. With meals
• B. Before bedtime
• C. On an empty stomach in the morning
• D. With a glass of milk

Correct answer: C

Rationale: Levothyroxine should be taken on an empty stomach in the morning to enhance absorption and efficacy. Taking it with meals (Choice A) may interfere with absorption due to food interactions. Taking it before bedtime (Choice B) can lead to difficulties with absorption and may disrupt the sleep cycle. Consuming levothyroxine with a glass of milk (Choice D) is not recommended as calcium in milk can interfere with its absorption. Therefore, the best practice is to take levothyroxine on an empty stomach in the morning to ensure optimal effectiveness.
