The nurse is discharging a client from the hospital who has a new prescription for furosemide. Which of the following client statements indicates an understanding of the teaching?
"I should eat a diet low in potassium while taking this medication."
"I should limit my fluid intake while taking this medication."
"My blood pressure will increase while I am taking this medication."
"I need to limit my sun exposure and wear sunscreen while on this medication."
The Correct Answer is D
Choice A reason: Furosemide does not require a diet low in potassium; in fact, patients may need to increase their potassium intake due to its diuretic effect.
Choice B reason: Patients on furosemide should not limit fluid intake unless specifically instructed by their healthcare provider, as the medication is a diuretic.
Choice C reason: Furosemide is used to treat high blood pressure, so it would not cause an increase in blood pressure.
Choice D reason: Limiting sun exposure and wearing sunscreen is important as furosemide can make the skin more sensitive to sunlight.

Correct Answer is ["2"]
Explanation
Step 1: The total amount of diphenhydramine required per dose is 50 mg.
Step 2: Each tablet contains 25 mg of diphenhydramine.
Step 3: To find out how many tablets are needed, we divide the total amount required by the amount in each tablet. So, 50 mg ÷ 25 mg/tablet.
Step 4: The result is 2 tablets.
So, the nurse should administer 2 tablets per dose. This is already a whole number, so no rounding is necessary.
Correct Answer is A
Explanation
Choice A reason: Acute tubular necrosis (ATN) is a condition where there is damage to the renal tubular cells, which can lead to a decrease in GFR. This is because the tubular cells are responsible for reabsorbing substances from the filtrate back into the blood. When these cells are injured, they cannot function properly, leading to a buildup of waste products and a decrease in GFR.
Choice B reason: While obstruction can lead to a decrease in GFR, it is not the primary cause in the context of acute tubular necrosis. Obstruction typically occurs in postrenal causes of acute kidney injury.
Choice C reason: In?ammatory cells do invade damaged kidneys, but this is more characteristic of conditions such as acute interstitial nephritis rather than ATN. In ATN, the primary issue is the injury to the tubular cells themselves.
Choice D reason: A reduction of blood flow to the kidneys, or prerenal azotemia, can indeed lead to a decrease in GFR. However, in the context of ATN, the primary issue is not the blood flow but the damage to the renal tubules.
