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 charge nurse is teaching a group of nurses about the correct use of restraints. Which of the following should the nurse include in the teaching?

A. Place a belt restraint on a school-age child who has seizures.
B. Secure wrist restraints to the bed rails for an adolescent.
C. Apply elbow immobilizers to an infant with a cleft lip injury.
D. Keep the side rails of a toddler's crib elevated.

Correct answer: D

Rationale: The correct use of restraints is crucial to ensure patient safety. Keeping the side rails of a toddler's crib elevated is a safe practice as it prevents falls and provides a level of protection without directly restraining the child. Placing a belt restraint on a child with seizures (Choice A) is inappropriate as it may restrict movement and cause harm during a seizure. Securing wrist restraints to bed rails for an adolescent (Choice B) is not recommended as it can lead to injuries and compromise circulation. Applying elbow immobilizers to an infant with a cleft lip injury (Choice C) is also incorrect as it does not address the issue of restraint and is not a standard practice in this situation.

3. A healthcare provider is providing discharge instructions to a client who has a new prescription for metformin. Which of the following instructions should the healthcare provider include?

A. Take this medication with meals.
B. Avoid consuming alcohol while taking this medication.
C. Take this medication at bedtime.
D. Report any muscle pain to your healthcare provider.

Correct answer: B

Rationale: The correct answer is B: 'Avoid consuming alcohol while taking this medication.' Clients taking metformin should avoid alcohol as it increases the risk of lactic acidosis. Choice A is incorrect because metformin is usually taken with meals to reduce gastrointestinal side effects. Choice C is incorrect as metformin is typically taken with meals, not at bedtime. Choice D is incorrect because muscle pain is not a common side effect of metformin.

4. How should pain be assessed in a non-verbal patient?

A. Observe facial expressions
B. Use the Wong-Baker faces scale
C. Assess heart rate
D. Ask the patient to rate their pain

Correct answer: A

Rationale: Observing facial expressions is essential in assessing pain levels in non-verbal patients. Non-verbal cues, such as facial grimacing, furrowed brows, or clenched jaws, can provide valuable information about the patient's pain experience. Using the Wong-Baker faces scale or assessing heart rate may not be as effective in non-verbal patients as they are unable to communicate their pain through these methods. Asking the patient to rate their pain is also not suitable for non-verbal patients as they may not have the ability to verbally communicate their pain levels.

5. Which lab value is critical for a patient on heparin therapy?

A. Monitor aPTT
B. Monitor INR
C. Monitor platelet count
D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial for patients on heparin therapy as it helps determine the clotting ability of the blood. By monitoring aPTT, healthcare providers can adjust the dosage of heparin to maintain therapeutic levels and prevent bleeding complications. Monitoring INR is more commonly associated with warfarin therapy, not heparin. Monitoring platelet count is important for assessing the risk of bleeding or clotting disorders but is not specific to heparin therapy. Monitoring sodium levels is not directly related to assessing the effectiveness or safety of heparin therapy.
