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.
Dextromethorphan.
Guaifenesin.
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 B
Explanation
Metoclopramide is a medication that increases muscle contractions in the upper digestive tract and speeds up the rate at which the stomach empties into the intestines. It is used to treat gastroparesis (slow stomach emptying) in people with diabetes, which can cause heartburn and stomach discomfort after meals.
Choice A is wrong because impaction is a condition where a large mass of dry, hard stool becomes stuck in the rectum and cannot be passed.
Metoclopramide does not treat impaction, but laxatives or enemas may be used instead.
Choice C is wrong because encopresis is a condition where a child over the age of 4 has involuntary bowel movements, usually due to chronic constipation.
Metoclopramide does not treat encopresis, but behavioral therapy, laxatives, or dietary changes may be used instead.
Choice D is wrong because metoclopramide is not used for clients requiring diagnostic procedures involving the stomach or intestines.
However, it may be used to prevent nausea and vomiting caused by chemotherapy or surgery.
Correct Answer is D
Explanation
Oxygen cannot diffuse rapidly across the membrane to tissues in the eye. Diabetic retinopathy is caused by damage to the blood vessels of the retina, which is the light-sensitive tissue at the back of the eye. This damage can reduce the oxygen supply to the retina and lead to vision problems.
Choice A is wrong because cells in the eye can reproduce normally, but they may not function properly due to high blood sugar levels or lack of oxygen.
Choice B is wrong because diabetic retinopathy does not affect the production of aqueous humor, which is the fluid that fills the front part of the eye.
However, diabetes can cause another eye condition called glaucoma, which is caused by increased pressure from too much aqueous humor.
Choice C is wrong because diabetic retinopathy does not affect the nerve innervations throughout the eye.
However, diabetes can cause another eye condition called diabetic neuropathy, which is caused by damage to the nerves that control eye movement and pupil dilation.
