A nurse is administering tetracycline to a client who has acne vulgaris. The client tells the nurse that he usually takes calcium supplements with his meals.
How should the nurse respond?
“You can continue to take calcium supplements as long as you take them with food.”
“You should avoid taking calcium supplements while you are on tetracycline therapy.”
“You can take calcium supplements with tetracycline as long as you drink plenty of water.”
“You should take calcium supplements at least 2 hours before or after tetracycline."
The Correct Answer is D
You should take calcium supplements at least 2 hours before or after tetracycline. This is because calcium can interfere with the absorption of tetracycline and reduce its effectiveness.
Choice A is wrong because taking calcium supplements with food does not prevent the interaction with tetracycline.
Choice B is wrong because avoiding calcium supplements altogether is not necessary and may deprive the client of an important nutrient.
Choice C is wrong because drinking plenty of water does not prevent the interaction with tetracycline either.
Normal ranges for calcium are 8.5 to 10.2 mg/dL for adults. Tetracycline is an antibiotic that is used to treat acne vulgaris and other infections. It should be taken on an empty stomach with a full glass of water.

Explanation
Hearing loss and nephrotoxicity are possible adverse effects of vancomycin, especially when used with other drugs that can affect the kidneys or ears, such as furosemide. The nurse should monitor the client’s renal function tests, serum vancomycin levels, and hearing acuity while receiving this combination of drugs.
Choice C, red man syndrome, is a hypersensitivity reaction to vancomycin that causes flushing, itching, and rash on the face, neck, and upper body.It is not related to furosemide use and can be prevented by slowing the infusion rate of vancomycin.
Choice D, hypokalemia, is a low level of potassium in the blood that can be caused by furosemide, a loop diuretic that increases the excretion of potassium.However, vancomycin does not affect potassium levels and does not increase the risk of hypokalemia.
Choice E, thrombocytopenia, is a low level of platelets in the blood that can cause bleeding problems.
It is a rare side effect of vancomycin that occurs in less than 1% of patients.It is not related to furosemide use and does not occur more frequently with this combination of drugs.
