Nursing Elites

1. A client with asthma is being taught how to use a peak flow meter by a nurse. Which of the following instructions should the nurse include?

• A. Blow as hard as possible into the mouthpiece.
• B. Exhale quickly and forcefully after taking a deep breath.
• C. Inhale as deeply as possible and then blow into the mouthpiece.
• D. Take a deep breath and hold it for 5 seconds before exhaling.

Correct answer: B

Rationale: The correct answer is B because the client should exhale quickly and forcefully into the peak flow meter after taking a deep breath to measure peak expiratory flow. Choice A is incorrect as blowing as hard as possible may not provide an accurate reading. Choice C is incorrect because inhaling deeply before blowing can affect the results. Choice D is incorrect as holding the breath before exhaling is not part of using a peak flow meter.

2. 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.

3. A nurse is caring for a client who has severe preeclampsia and is receiving magnesium sulfate intravenously. The nurse discontinues the magnesium sulfate after the client displays toxicity. Which of the following actions should the nurse take?

• A. Position the client supine.
• B. Prepare an IV bolus of dextrose 5% in water.
• C. Administer methylergonovine IM.
• D. Administer calcium gluconate IV.

Correct answer: D

Rationale: Administering calcium gluconate IV is the correct action when a client displays toxicity from magnesium sulfate. Calcium gluconate is used as the antidote for magnesium sulfate toxicity as it counteracts the effects. Positioning the client supine (Choice A) is not the immediate action needed. Administering dextrose 5% in water (Choice B) is not indicated for magnesium sulfate toxicity. Administering methylergonovine IM (Choice C) is used in postpartum hemorrhage, not for magnesium sulfate toxicity.

4. A nurse is assessing a client who is postoperative following a bowel resection. Which of the following findings should the nurse report to the provider?

• A. Heart rate 110/min.
• B. Temperature of 37.4°C (99.3°F).
• C. Respiratory rate of 18/min.
• D. Urine output of 20 mL/hr.

Correct answer: D

Rationale: A urine output of 20 mL/hr is below the expected range and indicates potential renal failure, requiring immediate intervention. In postoperative patients, a urine output less than 30 mL/hr suggests inadequate renal perfusion, a concern that needs prompt attention to prevent renal complications. The heart rate of 110/min, temperature of 37.4°C (99.3°F), and respiratory rate of 18/min are within normal ranges for a postoperative client and do not indicate immediate issues.

5. What is the best intervention for a patient experiencing respiratory distress?

• A. Administer oxygen
• B. Administer bronchodilators
• C. Administer IV fluids
• D. Provide chest physiotherapy

Correct answer: A

Rationale: Administering oxygen is the best intervention for a patient experiencing respiratory distress because it helps improve oxygenation and alleviate respiratory distress. Oxygen therapy is crucial in ensuring that the patient receives an adequate supply of oxygen to meet the body's demands. Administering bronchodilators (Choice B) may be beneficial in specific respiratory conditions like asthma or COPD but may not be the primary intervention in all cases of respiratory distress. Administering IV fluids (Choice C) may be necessary in cases of dehydration or shock but would not directly address respiratory distress. Providing chest physiotherapy (Choice D) can help mobilize secretions in conditions like cystic fibrosis but is not the first-line intervention for respiratory distress.
