A nurse is preparing to administer furosemide to a client who has acute heart failure.
Which of the following laboratory results should the nurse identify as a contraindication for receiving the medication?
Sodium 136 mEq/L.
Creatinine 0.8 mg/dL.
Potassium.2 mEq/L.
BUN 18 mg/dL.
The Correct Answer is C
Furosemide is a loop diuretic that can cause loss of potassium from the body.
A potassium level of.2 mEq/L is considered low (hypokalemia) and can be a contraindication for receiving the medication.
Sodium 136 mEq/L is within the normal range and is not a contraindication for receiving furosemide.
B) Creatinine 0.8 mg/dL is within the normal range and is not a contraindication for receiving furosemide.
D) BUN 18 mg/dL is within the normal range and is not a contraindication for receiving furosemide.

Correct Answer is C
Explanation
The fluctuation of fluid in the water-seal chamber of a chest tube is known as tidaling and is caused by the changes in pressure within the chest during respiration.
Choice A is not correct because tidaling does not indicate an air leak.
Choice B is not correct because tidaling does not necessarily mean that the lung is fully re-expanded.
Choice D is not correct because suction pressure does not cause tidaling.
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.
