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 with a history of heart failure is receiving furosemide. Which of the following laboratory values should the nurse monitor?

• A. Sodium 140 mEq/L
• B. Calcium 9.0 mg/dL
• C. Potassium 3.2 mEq/L
• D. Chloride 100 mEq/L

Correct answer: C

Rationale: The correct answer is C: Potassium 3.2 mEq/L. A potassium level of 3.2 mEq/L is below the normal range and should be monitored in clients receiving furosemide due to the risk of hypokalemia. Furosemide is a loop diuretic that can cause potassium depletion, leading to hypokalemia. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias. Choices A, B, and D are not directly impacted by furosemide therapy in the same way as potassium levels, making them less relevant for monitoring in this scenario.

3. A charge nurse on a medical-surgical unit is planning assignments for a licensed practical nurse (LPN) who has been sent from the unit due to a staffing shortage. Which of the following clients should the nurse delegate to the LPN?

• A. A client who has an Hgb of 6.3 g/dl and a prescription for packed RBCs.
• B. A client who sustained a concussion and has unequal pupils.
• C. A client who is postoperative following a bowel resection with an NG tube.
• D. A client who fractured his femur yesterday and is experiencing shortness of breath.

Correct answer: C

Rationale: The correct answer is C because a client who is postoperative following a bowel resection with an NG tube can be delegated to an LPN as this involves routine postoperative care. Option A involves administering packed RBCs which requires assessment and monitoring for potential adverse reactions, not suitable for delegation to an LPN. Option B requires neurological assessment and close monitoring due to the concussion, which is beyond the scope of an LPN. Option D involves a client with a recent fracture and shortness of breath, which requires urgent assessment and intervention beyond the LPN's scope of practice.

4. Which electrolyte imbalance is commonly seen in patients receiving furosemide?

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

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, resulting in hypokalemia. This electrolyte imbalance necessitates close monitoring to prevent complications such as cardiac arrhythmias. Choices B, C, and D are incorrect. Hypercalcemia is not a common side effect of furosemide. Hyponatremia is more commonly associated with other medications like thiazide diuretics. Hyperkalemia is the opposite electrolyte imbalance and is not typically seen with furosemide use.

5. A client receiving intermittent enteral feedings is being cared for by a nurse. Which action should the nurse take to reduce the risk of aspiration?

• A. Administer the feeding over 60 minutes.
• B. Position the client in a supine position during feedings.
• C. Elevate the head of the bed to 45 degrees during feedings.
• D. Flush the feeding tube with 60 mL of water before each feeding.

Correct answer: C

Rationale: The correct action to reduce the risk of aspiration during enteral feedings is to elevate the head of the bed to 45 degrees. This position helps prevent the reflux of feeding into the lungs. Administering the feeding over 60 minutes (Choice A) does not directly reduce the risk of aspiration. Positioning the client in a supine position (Choice B) increases the risk of aspiration as it promotes reflux. Flushing the feeding tube with water (Choice D) is important for tube patency but does not directly reduce the risk of aspiration.
