A client presents at the clinic with a dry nonproductive cough. The client is diagnosed with bronchitis, and it has been determined that assistance is needed in thinning the sputum so the cough can become productive.
What does the nurse expect the provider will prescribe?

Benzonatate.

Dextromethorphan.

Guaifenesin.

Answer and Explanation

The Correct Answer is D

Guaifenesin is an expectorant that helps thin and loosen mucus in the lungs, making it easier to cough up the sputum. Some possible explanations for the other choices are:

Choice A. Benzonatate is wrong because benzonatate is an antitussive that suppresses the cough reflex by numbing the throat and lungs.

It does not help with sputum production or clearance.

Choice B. Dextromethorphan is wrong because dextromethorphan is also an antitussive that acts on the brain to reduce the urge to cough.

It does not affect the mucus or bronchial secretions.

Choice C. Hydrocodone is wrong because hydrocodone is a narcotic antitussive that works by binding to opioid receptors in the brain and spinal cord, blocking pain signals and decreasing cough.

It can cause sedation, respiratory depression, and dependence, and is not indicated for bronchitis.

Normal ranges for sputum production vary depending on the individual and the cause of the cough, but generally range from 10 to 100 mL per day.

Excessive or abnormal sputum may indicate an infection, inflammation, or obstruction of the airways.

Correct Answer is D

Explanation

Famotidine Tablet 20mg - Hillside Veterinary Surgery

Famotidine is a histamine type 2 receptor antagonist (H blocker) which is commonly used for treatment of acid-peptic disease and heartburn. Famotidine has been linked to rare instances of clinically apparent acute liver injury, but it is less likely to cause hepatotoxicity than cimetidine, another H blocker. Famotidine also has fewer drug interactions than cimetidine.

Choice A is wrong because nizatidine is another H blocker that can cause mild and transient serum aminotransferase elevations.

Nizatidine has not been linked to cases of clinically apparent liver injury, but it has not been widely used.

Choice B is wrong because ranitidine is another H blocker that can cause mild and transient serum aminotransferase elevations.

Ranitidine has also been associated with rare instances of clinically apparent liver injury, some of which were fatal or required liver transplantation.

Choice C is wrong because cimetidine is another H blocker that can cause mild and transient serum aminotransferase elevations.

Cimetidine has also been implicated in several cases of clinically apparent acute liver injury, some of which were severe and led to acute liver failure and death.

Cimetidine also has many drug interactions due to its inhibition of cytochrome P enzymes.

Normal ranges for serum aminotransferases are 7 to 56 U/L for alanine aminotransferase (ALT) and 10 to 40 U/L for as

A. “Remain in the upright position for 30 minutes after taking it.”. B. “Take the medication with a full glass of water.”. C. “Take the medication before going to bed at night.”. D. “Take the medication after breakfast.”.

Correct Answer is B

Explanation

Levothyroxine is a synthetic thyroid hormone that is used to treat hypothyroidism. It should be taken on an empty stomach, preferably in the morning, with a full glass of water to facilitate absorption and prevent choking. Taking the medication with food or other substances may interfere with its effectiveness.

Choice A is wrong because levothyroxine does not need to be taken after breakfast.

In fact, taking it after breakfast may reduce its absorption and efficacy.

Choice C is wrong because levothyroxine does not require the patient to remain in the upright position for 30 minutes after administering.

This instruction is more applicable to bisphosphonates, which are drugs used to treat osteoporosis.

Choice D is wrong because levothyroxine should not be taken at night.

Taking it at night may cause insomnia, as well as reduced absorption and efficacy.
