The practical nurse (PN) gives the expectorant guaifenesin to a client with an upper respiratory tract infection. Which statement shows that the client has understood the instructions related to the use of the expectorant?
“It is best to take this medication with meals to prevent nausea.”.
“I should stay upright for 30 minutes after taking it to prevent indigestion.”.
“I will increase my fluid intake to help me cough up the sputum.”.
“To prevent injury, I should not combine this medication with levothyroxine.”.
Have you noticed the need to urinate less often?
The Correct Answer is C
Choice A rationale
While taking medication with meals can sometimes help prevent nausea, this is not specifically related to the use of the expectorant guaifenesin. Therefore, this statement does not show that the client has understood the instructions related to the use of the expectorant.
Choice B rationale
Staying upright for 30 minutes after taking medication can sometimes help prevent indigestion, but this is not specifically related to the use of the expectorant guaifenesin. Therefore, this statement does not show that the client has understood the instructions related to the use of the expectorant.
Choice C rationale
Increasing fluid intake can help loosen mucus or phlegm in the lungs, which is the primary purpose of an expectorant like guaifenesin. Therefore, this statement shows that the client has understood the instructions related to the use of the expectorant.
Choice D rationale
While it’s important to avoid combining certain medications due to potential interactions, there’s no specific interaction between guaifenesin and levothyroxine that would cause injury. Therefore, this statement does not show that the client has understood the instructions related to the use of the expectorant.

Metronidazole is an antibiotic used to treat various infections. Seizure activity is a serious side effect of metronidazole and should be reported to the charge nurse immediately.

While headache is a common side effect of metronidazole, it is not as serious as seizure activity and does not necessarily need to be reported to the charge nurse unless it is severe or persistent.
Choice C rationale
A metallic taste in the mouth is a common side effect of metronidazole. It is not a serious side effect and does not need to be reported to the charge nurse.
Choice D rationale
Abdominal cramping can be a side effect of metronidazole. However, it is not as serious as seizure activity and does not necessarily need to be reported to the charge nurse unless it is severe or persistent.
Correct Answer is A
Explanation
Choice A rationale
Minoxidil is an antihypertensive vasodilating agent used for resistant hypertension. It reduces peripheral resistance and produces a fall in blood pressure. One of the side effects of minoxidil can be mouth dryness. Therefore, mouth dryness can indicate that the minoxidil is having its intended therapeutic effect.
Choice B rationale
Dizziness while sitting up is not a therapeutic result of minoxidil. It could be a side effect or a symptom of orthostatic hypotension, which is a form of low blood pressure.
Choice C rationale
Blood glucose level of 218 mg/dl is not related to the therapeutic effect of minoxidil. Minoxidil is not used to control blood glucose levels. It’s used primarily to treat high blood pressure.
Choice D rationale
Pain rated at 1/10 is not a direct therapeutic result of minoxidil. Minoxidil is not an analgesic medication and does not directly affect pain levels.
