Which of the following client statements would cause the nurse to further question the client?

Choice A reason: Sufficient medication in the PCA syringe does not indicate effective pain management. It may reflect underuse due to inadequate pain control or patient misunderstanding of PCA use. Pain relief is assessed by patient-reported outcomes, not medication volume remaining.

Choice B reason: Sleeping and being difficult to arouse suggests oversedation, a potential adverse effect of PCA, particularly with opioids. This indicates excessive dosing rather than effective pain management, risking respiratory depression or other complications, requiring immediate dose adjustment or monitoring.

Choice C reason: A pain rating of 2 on a 0 to 10 scale indicates effective pain management. PCA allows patients to self-administer doses within safe limits, achieving low pain levels without excessive sedation, reflecting optimal balance of analgesia and patient safety post-trauma.

Choice D reason: Pressing the PCA button shows patient engagement but not pain control effectiveness. Frequent pressing may indicate inadequate relief, while infrequent use could reflect sufficient control or misunderstanding. Patient-reported pain levels are the primary indicator of PCA efficacy.

Choice A reason: Furosemide 60 mg requires 1.5 tablets of 40 mg (60 ÷ 40 = 1.5). Scored tablets allow precise division, ensuring the correct dose. This calculation aligns with safe medication administration principles, delivering the prescribed amount accurately.

Choice B reason: Administering 2.5 tablets (100 mg) exceeds the prescribed 60 mg dose. Overdosing furosemide, a loop diuretic, risks excessive diuresis, leading to dehydration, hypokalemia, or hypotension, making this choice unsafe and incorrect.

Choice C reason: Two tablets (80 mg) also exceed the 60 mg order. This overdose could cause significant fluid and electrolyte imbalances, particularly in vulnerable patients, as furosemide promotes rapid sodium and water excretion, making this choice inappropriate.

Choice D reason: One tablet (40 mg) underdoses the patient, providing only 66.7% of the prescribed 60 mg. Inadequate dosing may fail to achieve therapeutic effects, such as edema reduction or blood pressure control, rendering this choice incorrect.
