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 nurse is providing teaching to a client who has a new prescription for an albuterol inhaler. Which of the following instructions should the nurse include?
- A. Take one puff every 5 minutes until symptoms improve.
- B. Hold your breath for 10 seconds after inhaling the medication.
- C. Shake the inhaler for 2 seconds before use.
- D. Exhale forcefully after each puff.
Correct answer: B
Rationale: The correct answer is B. Instructing the client to hold their breath for 10 seconds after inhaling the medication allows it to reach deeper into the lungs for maximum effectiveness. Choice A is incorrect because taking one puff every 5 minutes may lead to overuse of the medication. Choice C is incorrect as shaking the inhaler for only 2 seconds may not provide adequate mixing of the medication. Choice D is incorrect because exhaling forcefully after each puff may reduce the amount of medication that reaches the lungs.
3. A nurse is assessing a client who has chronic heart failure. Which of the following findings indicates that the client is experiencing fluid overload?
- A. Increased urine output
- B. Bounding peripheral pulses
- C. Weight loss
- D. Decreased heart rate
Correct answer: B
Rationale: In clients with chronic heart failure, bounding peripheral pulses are a classic sign of fluid overload. This occurs due to increased volume in the arterial system, causing a forceful pulse. Increased urine output (Choice A) is often seen in clients with fluid volume deficit, not overload. Weight loss (Choice C) is also inconsistent with fluid overload as it suggests a fluid deficit. Decreased heart rate (Choice D) is more commonly associated with conditions like bradycardia, hypothyroidism, or the use of certain medications, but not specifically indicative of fluid overload in chronic heart failure.
4. A nurse is caring for a client who has a new temporary synchronous pacemaker. Which of the following should the nurse report to the provider?
- A. The client's pulse oximetry level is 96%.
- B. The client develops hiccups.
- C. The ECG shows pacing spikes after the QRS complex.
- D. The client's heart rate is 90 beats per minute.
Correct answer: C
Rationale: The correct answer is C. Pacing spikes after the QRS complex indicate a malfunction of the pacemaker and should be reported. Choice A is not directly related to the pacemaker function. Choice B, hiccups, are common and not typically associated with pacemaker issues. Choice D, a heart rate of 90 beats per minute, is within the normal range and does not indicate a pacemaker malfunction.
5. A nurse is providing teaching to a client who has a new prescription for levothyroxine. Which of the following instructions should the nurse include?
- A. Take this medication on an empty stomach.
- B. Take this medication at bedtime.
- C. Take this medication with food.
- D. Take this medication with a calcium supplement.
Correct answer: A
Rationale: The correct answer is A: 'Take this medication on an empty stomach.' Levothyroxine should be taken on an empty stomach to enhance absorption. Taking it with food or at bedtime can interfere with its absorption. Calcium supplements should also be avoided when taking levothyroxine as they can reduce its absorption.
