A nurse is reviewing a cardiac rhythm strip of a client who has atrial flutter.
Which of the following findings should the nurse expect?
Progressively longer PR durations.
Undetectable P waves.
A saw-tooth pattern with an atrial rate of 250 to 400/min.
Absent PR intervals with a ventricular rate of 40 to 60/min.
The Correct Answer is C
A saw-tooth pattern with an atrial rate of 250 to 400/min is a characteristic finding on a cardiac rhythm strip of a client who has atrial flutter.
Choice A is incorrect because progressively longer PR durations are characteristic of a Mobitz type I second-degree AV block, not atrial flutter.
Choice B is incorrect because undetectable P waves are characteristic of atrial fibrillation, not atrial flutter.
Choice D is incorrect because absent PR intervals with a ventricular rate of 40 to 60/min are characteristic of third-degree AV block, not atrial flutter.

Correct Answer is B
Explanation
After inhaling deeply using an incentive spirometer, you should hold your breath for 3 to 5 seconds before exhaling.
Choice A is wrong because exhaling slowly through pursed lips is not an instruction for using an incentive spirometer.
Choice C is wrong because placing hands on the upper abdomen during inhalation is not an instruction for using an incentive spirometer.
Choice D is wrong because positioning the mouthpiece.5 cm (1 in) from the mouth is not an instruction for using an incentive spirometer.
Correct Answer is B
Explanation
The correct answer is: b. “I apply a lubricating lotion to the cracked areas on the soles of my feet every morning.”
Choice A reason: Elevating the feet for long periods is not generally recommended for clients with Peripheral Arterial Disease (PAD). This is because elevation can decrease arterial blood flow to the feet, which is already compromised in PAD. The goal is to promote blood flow to the extremities, and elevation might work against this, especially if done for extended periods.
Choice B reason: Applying a lubricating lotion to the feet, particularly on the soles where the skin can become very dry and cracked, is beneficial for someone with PAD. It helps to maintain skin integrity and prevent skin breakdown, which can lead to serious complications due to the reduced blood flow and healing capacity in PAD.
Choice C reason: Soaking the feet in hot water is not advisable for individuals with PAD. They may have reduced sensation in their feet due to poor circulation, which increases the risk of burns from hot water. Additionally, prolonged soaking can lead to maceration of the skin, making it more susceptible to injury and infection.
Choice D reason: Using a heating pad, even on a low setting, to keep the feet warm is risky for clients with PAD. Due to decreased sensation from poor circulation, there is a danger of burns because the client may not feel how hot the heating pad is. It’s better to wear warm socks or use room temperature control to keep the feet warm.
