A nurse is preparing to teach a client about the use of a peak flow meter. Which of the following instructions should the nurse include?
- A. Place the mouthpiece in your mouth and blow out as quickly as you can.
- B. Exhale slowly into the mouthpiece over 5 seconds.
- C. Take a slow deep breath before blowing into the mouthpiece.
- D. Blow into the mouthpiece at a steady rate for 3 seconds.
Correct Answer: A
Rationale: The correct instruction for using a peak flow meter is to place the mouthpiece in your mouth and blow out as quickly as you can. This action helps measure the peak expiratory flow of the client. Choice B is incorrect because exhaling slowly does not provide an accurate peak flow reading. Choice C is incorrect as taking a slow deep breath before blowing interferes with obtaining an accurate measurement. Choice D is incorrect as blowing at a steady rate for 3 seconds may not reflect the peak expiratory flow accurately.

A nurse is caring for a client who is 1 day postoperative following a total knee replacement. The client reports pain of 8 on a scale of 0 to 10. Which of the following actions should the nurse take?
- A. Administer ibuprofen 400 mg PO
- B. Administer oxycodone 10 mg PO
- C. Reposition the client to the unaffected side
- D. Apply a cold compress to the affected knee
Correct Answer: B
Rationale: In this scenario, the appropriate action for the nurse to take when a client reports severe postoperative pain of 8 out of 10 is to administer oxycodone 10 mg PO. Oxycodone is a potent analgesic that is more effective in managing severe pain compared to ibuprofen, making choice A incorrect. Repositioning the client to the unaffected side or applying a cold compress may provide some comfort but are not the priority interventions for severe postoperative pain, making choices C and D less appropriate.
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.
A client has a new prescription for hydrochlorothiazide. Which of the following instructions should the nurse include?
- A. Take this medication at bedtime to prevent dizziness.
- B. Increase your intake of potassium-rich foods.
- C. Take this medication with food to prevent gastrointestinal upset.
- D. This medication can increase your blood pressure.
Correct Answer: B
Rationale: The correct instruction that the nurse should include for a client prescribed hydrochlorothiazide is to increase their intake of potassium-rich foods. Hydrochlorothiazide is a diuretic that can lead to potassium depletion, so increasing potassium-rich foods helps prevent hypokalemia. Option A is incorrect because hydrochlorothiazide is usually taken in the morning to prevent diuresis at night. Option C is not necessary as hydrochlorothiazide can be taken with or without food. Option D is incorrect because hydrochlorothiazide is used to lower blood pressure, not increase it.
A client who is at 10 weeks of gestation and experiencing nausea and vomiting is receiving teaching from a nurse. Which of the following statements should the nurse include?
- A. You should eat crackers before getting out of bed.
- B. You should drink ginger ale with your meals.
- C. You should lie down for 30 minutes after eating.
- D. You should avoid eating between meals.
Correct Answer: A
Rationale: The correct answer is A: 'You should eat crackers before getting out of bed.' Eating crackers before getting out of bed can help reduce nausea and vomiting during pregnancy. This recommendation helps in stabilizing blood sugar levels before fully waking up. Choice B is incorrect because ginger ale may exacerbate nausea due to its carbonation. Choice C is incorrect as lying down after eating can worsen symptoms of nausea. Choice D is incorrect as avoiding eating between meals can lead to low blood sugar levels, worsening nausea and vomiting.
A client has a new diagnosis of COPD. Which of the following instructions should the nurse include in the teaching?
- A. Breathe rapidly through your mouth when using the incentive spirometer.
- B. Use pursed-lip breathing during periods of dyspnea.
- C. Avoid drinking fluids during meals.
- D. Use diaphragmatic breathing during periods of dyspnea.
Correct Answer: B
Rationale: Pursed-lip breathing is a beneficial technique for clients with COPD as it helps control shortness of breath and improves oxygenation. This technique involves inhaling slowly through the nose and exhaling through pursed lips, which helps keep airways open. Option A is incorrect as breathing rapidly through the mouth when using the incentive spirometer can lead to hyperventilation. Option C is incorrect because it is important for clients with COPD to stay hydrated by drinking fluids between meals, but not during meals which can cause bloating and discomfort. Option D is incorrect as diaphragmatic breathing, though beneficial, is not the preferred technique for managing dyspnea in COPD; pursed-lip breathing is more effective.
