A patient is taking guaifenesin as part of treatment for a sinus infection. Which instruction will the nurse include during patient teaching?

Report symptoms that last longer than 2 days.

Report clear-colored sputum to the prescriber.

Avoid driving a car or operating heavy machinery because of the sedating effects.

Increase fluid intake to help loosen and liquefy secretions.

Answer and Explanation

The Correct Answer is D

Choice A reason: This is incorrect because reporting symptoms that last longer than 2 days is not specific to guaifenesin. This is a general instruction for any patient with a sinus infection, regardless of the medication they are taking.

Choice B reason: This is incorrect because reporting clear-colored sputum to the prescriber is not necessary. Clear-colored sputum indicates that the infection is improving and the mucus is thinning. This is a desired effect of guaifenesin, not a problem that needs to be reported.

Choice C reason: This is incorrect because guaifenesin does not have sedating effects. Guaifenesin is an expectorant that helps to break up and expel mucus from the respiratory tract. It does not cause drowsiness or impair the ability to drive or operate machinery.

Choice D reason: This is correct because increasing fluid intake is an important instruction for a patient taking guaifenesin. Fluids help to hydrate the body and thin the mucus, making it easier to cough up and clear the sinuses. Fluids also help to prevent dehydration and dryness of the mucous membranes.

Correct Answer is C

Explanation

Choice A reason: This is incorrect because the dosage is given in the prescription as 500 mg, which indicates the amount of the drug to be administered.

Choice B reason: This is incorrect because the route is given in the prescription as PO, which stands for per os or by mouth, which indicates how the drug is to be administered.

Choice C reason: This is correct because the medication is not given in the prescription, which is the name of the drug to be administered. The nurse should ask the provider to clarify the medication name and spell it out if necessary.

Choice D reason: This is incorrect because the time/frequency is given in the prescription as BID, which stands for bis in die or twice a day, which indicates when and how often the drug is to be administered.

A. Venous thromboembolism B. Breast cancer C. Hypocalcemia D. Stress fractures

Correct Answer is A

Explanation

Choice A reason: Venous thromboembolism is a contraindication for taking SERMs. SERMs are drugs that act like estrogen in some tissues and block estrogen in others. They can help prevent bone loss and fractures in postmenopausal women, but they can also increase the risk of blood clots in the veins, such as deep vein thrombosis and pulmonary embolism. Therefore, women who have a history of or are at high risk for venous thromboembolism should not take SERMs.

Choice B reason: Breast cancer is not a contraindication for taking SERMs. In fact, some SERMs, such as tamoxifen and raloxifene, are used to treat or prevent breast cancer in women who have estrogen receptor-positive tumors. These SERMs block the effects of estrogen in the breast tissue and reduce the growth of cancer cells.

Choice C reason: Hypocalcemia is not a contraindication for taking SERMs. Hypocalcemia is a low level of calcium in the blood. SERMs do not affect calcium levels directly, but they can help prevent calcium loss from the bones by mimicking the effects of estrogen in the bone tissue. However, women who take SERMs should also take adequate calcium and vitamin D supplements to maintain bone health.

Choice D reason: Stress fractures are not a contraindication for taking SERMs. Stress fractures are small cracks in the bones that result from repeated stress or overuse. SERMs can help prevent stress fractures by strengthening the bones and reducing the risk of osteoporosis. However, women who take SERMs should also avoid excessive or inappropriate physical activity that can cause stress fractures.
