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.

Explanation
The nurse should ask this question because the client is taking a chemical stimulant laxative, which can cause dehydration and electrolyte imbalance, especially in combination with medications for heart failure and osteoarthritis that may also affect fluid and electrolyte balance. The nurse should assess the client’s hydration status and risk of hypovolemia or hypotension.
Choice B. Timing of medication administration is wrong because it is not the priority question in this situation.
The nurse should ask this question later to determine if the client is taking the medications as prescribed and if there are any drug interactions or adverse effects.
Choice C. Previous effectiveness of laxatives is wrong because it is not relevant to the client’s current condition.
The nurse should ask this question later to evaluate the client’s bowel habits and history of constipation.
Choice D. The amount of fiber intake is wrong because it is not the priority question in this situation.
The nurse should ask this question later to educate the client about dietary measures to prevent constipation and promote bowel health.
Correct Answer is A
Explanation
Desmopressin is a synthetic analog of antidiuretic hormone (ADH) that acts on the kidneys to increase water reabsorption and decrease urine output. Neurogenic diabetes insipidus is a condition caused by a deficiency of ADH due to damage to the hypothalamus or pituitary gland. Patients with this condition have excessive thirst and urination, dehydration, and low urine specific gravity.
Choice B. Methylprednisolone is wrong because it is a corticosteroid that suppresses inflammation and immune response.
It is not used to treat diabetes insipidus.
Choice C. Dexamethasone is wrong because it is also a corticosteroid that has similar effects as methylprednisolone.
It is not used to treat diabetes insipidus.
Choice D. Physostigmine is wrong because it is a cholinesterase inhibitor that increases the levels of acetylcholine in the body.
