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?

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.

A. Observe the client for development of involuntary movements of the lips and tongue. B. Administer the medication at least 30 minutes before the client’s meals. C. Assess the skin daily for areas of ecchymosis or other signs of bleeding. D. Ensure peak and trough serum levels are collected with the third dose of medication.

Correct Answer is C

Explanation

Choice A rationale

Involuntary movements of the lips and tongue are typically associated with antipsychotic medications, not nonsteroidal anti-inflammatory drugs (NSAIDs) like ketorolac15. Therefore, observing the client for these symptoms would not be a relevant intervention for a client taking ketorolac15.

Choice B rationale

Administering the medication at least 30 minutes before meals is not a specific requirement for ketorolac15. Therefore, this would not be a necessary intervention for a client taking this medication15.

Choice C rationale

Ketorolac, like other NSAIDs, can increase the risk of bleeding15. This can manifest as areas of ecchymosis (bruising) or other signs of bleeding on the skin15. Therefore, assessing the skin daily for these signs would be an important intervention for a client taking ketorolac15.

Choice D rationale

Peak and trough serum levels are typically monitored for medications with a narrow therapeutic index, such as certain antibiotics15. Ketorolac does not typically require

monitoring of serum levels15. Therefore, ensuring peak and trough serum levels are collected would not be a necessary intervention for a client taking this medication15.
