The practical nurse (PN) is assisting with the plan of care (POC) for a client with costochondritis who is now experiencing increased discomfort in breathing. The client receives a prescription for meloxicam. Which intervention should the PN include in the client’s POC?
Ensure peak and trough serum levels are collected with the third medication dose
Reassess the client’s pain 30 minutes after medication administration
Observe the client daily for involuntary movements of the lips and tongue
Initiate strict intake and output measurements and record every shift
The Correct Answer is B
Choice A reason: Peak and trough levels are relevant for drugs like antibiotics, not meloxicam, a nonsteroidal anti-inflammatory drug (NSAID). Meloxicam’s efficacy is assessed clinically, not via blood levels, as it reduces inflammation and pain, making this choice irrelevant for costochondritis management.
Choice B reason: Reassessing pain 30 minutes after meloxicam administration evaluates its effectiveness, as this NSAID inhibits cyclooxygenase, reducing prostaglandin-mediated inflammation and pain in costochondritis. Timely reassessment ensures adequate pain relief, guiding further interventions for breathing discomfort, making this the appropriate intervention.
Choice C reason: Involuntary lip and tongue movements are associated with antipsychotics, not meloxicam. This NSAID does not cause neurological side effects like tardive dyskinesia. Monitoring for this is irrelevant, as meloxicam’s primary concerns are gastrointestinal or renal, not movement disorders.
Choice D reason: Strict intake and output monitoring is unnecessary for meloxicam, which primarily affects inflammation, not fluid balance. While long-term use may impact kidneys, pain reassessment is more immediate for costochondritis, making this choice less relevant than evaluating therapeutic pain relief.

Correct Answer is B
Explanation
Choice A reason: Stopping disulfiram for nausea or vomiting is incorrect, as these are expected in alcohol reactions, not side effects warranting discontinuation. Disulfiram inhibits aldehyde dehydrogenase, causing acetaldehyde buildup if alcohol is consumed, leading to these symptoms, which reinforce alcohol avoidance.
Choice B reason: Avoiding all alcohol, including in cough syrups, is critical, as disulfiram causes severe reactions (flushing, nausea) by blocking acetaldehyde metabolism. Even small amounts trigger symptoms, reinforcing abstinence in alcohol dependence treatment, making this the most important instruction for safety and efficacy.
Choice C reason: Taking disulfiram at the same time daily promotes adherence but is less critical than avoiding alcohol, which directly prevents severe reactions. Consistency aids therapeutic levels, but alcohol exposure poses immediate health risks, making this instruction secondary.
Choice D reason: Weekly blood tests are not standard for disulfiram, as therapeutic levels are not routinely monitored, and sodium is unaffected. Liver function may be checked periodically, but alcohol avoidance is the priority to prevent acute reactions, making this choice incorrect.
Correct Answer is A
Explanation
Choice A reason: Polyethylene glycol, a bowel prep for colonoscopy, requires rapid drinking at specified intervals to ensure effective colon cleansing. This osmotic laxative draws water into the bowel, promoting evacuation. Consistent, rapid intake ensures complete bowel clearance, critical for clear visualization during the procedure.
Choice B reason: Diluting polyethylene glycol with fruit juice is incorrect, as it may alter the solution’s osmotic balance, reducing efficacy. The preparation must remain undiluted to draw sufficient water into the colon for cleansing, making this instruction inappropriate for achieving a clear colonoscopy.
Choice C reason: Drinking polyethylene glycol with a meal is incorrect, as food can interfere with bowel cleansing. The solution is taken on an empty stomach, typically the day before the exam, to ensure the colon is clear, making this instruction counterproductive to the prep’s purpose.
Choice D reason: Watery diarrhea is the expected outcome of polyethylene glycol, not an adverse effect requiring reporting. It indicates effective bowel cleansing for colonoscopy. Instructing to report this normal response is unnecessary and may cause confusion, as diarrhea is the goal of the preparation.
