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 lispro insulin is a rapid-acting insulin that does not need to be administered with another type of insulin. However, the patient may need a long-acting or intermediate-acting insulin to provide basal coverage throughout the day.

Choice B reason: This is incorrect because lispro insulin has a peak action of 30 to 90 min after the injection, which means that the patient is at the highest risk of hypoglycemia during this time. The nurse should assess for hypoglycemia more frequently than 4 hr after the injection.

Choice C reason: This is correct because lispro insulin has a fast onset of action of 15 to 30 min after the injection, which means that the patient should eat a meal within 15 min of the injection to prevent hypoglycemia.

Choice D reason: This is incorrect because polyuria is a sign of hyperglycemia, not hypoglycemia. The nurse should monitor for polyuria before the insulin injection, as it may indicate that the patient's blood glucose level is high.

A. Withhold all medications as ordered. B. Contact the prescriber to clarify orders. C. Administer half the original dose. D. Give the medication with a sip of water.

Correct Answer is B

Explanation

Choice A reason: This is incorrect because withholding all medications may cause hyperglycemia or ketoacidosis in the patient, especially if they are taking insulin or sulfonylureas. The nurse should consult with the prescriber to adjust the dose or timing of the medications according to the patient's blood glucose level and the duration of the procedure.

Choice B reason: This is correct because contacting the prescriber to clarify orders is the best action by the nurse, as the prescriber can provide specific instructions on how to manage the patient's oral antidiabetic drugs before and after the oral endoscopy. The nurse should also monitor the patient's blood glucose level closely and report any abnormal findings to the prescriber.

Choice C reason: This is incorrect because administering half the original dose may not be appropriate for the patient, as it may cause hypoglycemia or hyperglycemia depending on the type and dose of the medication and the patient's blood glucose level. The nurse should not make any changes to the medication regimen without the prescriber's approval.

Choice D reason: This is incorrect because giving the medication with a sip of water may violate the NPO status of the patient, which is necessary to prevent aspiration or interference with the oral endoscopy. The nurse should not administer any oral medications or fluids to the patient unless the prescriber allows it.
