A.

“It is best to take this medication with meals to prevent nausea.”.

B.

“I should stay upright for 30 minutes after taking it to prevent indigestion.”.

C.

“I will increase my fluid intake to help me cough up the sputum.”.

D.

“To prevent injury, I should not combine this medication with levothyroxine.”.

E.

Have you noticed the need to urinate less often?

Answer and Explanation

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.

Correct Answer is A

Explanation

Choice A rationale
The patient is receiving a nucleoside/nucleotide reverse transcriptase inhibitor (NRTI) for HIV
treatment and reports experiencing malaise, fatigue, and anorexia. These symptoms, along
with the observed increased respiratory rate, could be indicative of liver toxicity, a known
potential side effect of NRTIs. Therefore, reviewing liver function tests would be most
important in this case.
Choice B rationale
While arterial blood gases can provide valuable information about a patient’s respiratory
status, they may not be the most relevant in this context. The patient’s symptoms and the side
effect profile of NRTIs suggest that liver function may be a more pressing concern.

Choice C rationale
A complete blood count (CBC) can provide a broad overview of a patient’s general health, but it
may not provide the specific information needed to assess the patient’s current symptoms and
potential medication side effects.
Choice D rationale
A basic metabolic panel can provide information about a patient’s kidney function, electrolyte
levels, and blood sugar levels, among other things. However, given the patient’s symptoms and
medication regimen, liver function tests may be more relevant.

Correct Answer is C

Explanation

Choice A rationale
Diminished urinary urgency is an expected outcome of oxybutynin treatment, as the
medication works by relaxing the muscles of the bladder.

Choice B rationale
Reduced urinary frequency is another expected outcome of oxybutynin treatment.

Choice C rationale
Decreased urinary output is not a typical effect of oxybutynin. In fact, oxybutynin is used to
manage symptoms of an overactive bladder, which include frequent urination. Therefore, if the
PN observes decreased urinary output, it could indicate a problem such as urinary retention,
which should be reported to the charge nurse.

Choice D rationale
Less frequent urinary incontinence is an expected outcome of oxybutynin treatment.
