Nursing Elites

1. A nurse is reviewing the laboratory results of a client who has hypokalemia. Which of the following findings should the nurse expect?

• A. Serum potassium 5.4 mEq/L
• B. Flat T waves
• C. Elevated ST segments
• D. Bradycardia

Correct answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

2. A client has a new prescription for levothyroxine. Which of the following instructions should the nurse include?

• A. Take this medication in the evening before bed.
• B. Take this medication on an empty stomach.
• C. Take this medication with a full glass of milk.
• D. Take this medication with an antacid if you experience indigestion.

Correct answer: B

Rationale: The correct instruction when taking levothyroxine is to take it on an empty stomach. This enhances absorption and ensures the medication's effectiveness. Taking it with food or other substances, such as milk or antacids, can interfere with its absorption. Therefore, choices A, C, and D are incorrect.

3. A client with a new diagnosis of celiac disease is receiving teaching from a nurse. Which of the following client statements indicates an understanding of the teaching?

• A. I can still have oatmeal for breakfast.
• B. I need to avoid foods that contain gluten.
• C. I can have rye toast with my eggs.
• D. I can continue to eat foods made from barley.

Correct answer: B

Rationale: The correct answer is B because clients with celiac disease should avoid gluten, which is found in foods like rye and barley. Choice A is incorrect because oatmeal may contain gluten unless specified gluten-free. Choice C is incorrect as rye contains gluten. Choice D is incorrect as barley contains gluten.

4. A client with osteoporosis is being taught by a nurse about preventing bone loss. Which of the following instructions should the nurse include?

• A. Take a calcium supplement once a day.
• B. Avoid weight-bearing exercises.
• C. Walk for 30 minutes 3 times per week.
• D. Increase intake of high-phosphorus foods.

Correct answer: C

Rationale: The correct answer is C: 'Walk for 30 minutes 3 times per week.' Walking is a weight-bearing exercise that helps prevent bone loss and improve overall health in clients with osteoporosis. Option A is incorrect because while calcium is essential for bone health, simply taking a supplement is not sufficient for preventing bone loss. Option B is incorrect because weight-bearing exercises are actually beneficial for improving bone density and strength. Option D is incorrect because high-phosphorus foods do not play a significant role in preventing bone loss in osteoporosis.

5. A nurse is assessing a client who is immediately postoperative following a subtotal thyroidectomy. Which of the following should the nurse expect to administer?

• A. Calcium gluconate
• B. Sodium bicarbonate
• C. Potassium chloride
• D. Sodium phosphate

Correct answer: A

Rationale: Calcium gluconate is the correct answer because it is administered to treat hypocalcemia, a common complication post-thyroidectomy. After a thyroidectomy, there is a risk of damaging the parathyroid glands, which can lead to a decrease in calcium levels. Administering calcium gluconate helps to raise calcium levels. Sodium bicarbonate (Choice B) is not typically indicated for immediate postoperative care following a subtotal thyroidectomy. Potassium chloride (Choice C) is not directly related to the common complications of this specific surgery. Sodium phosphate (Choice D) is not typically used to address immediate postoperative issues post-thyroidectomy.
