The nurse is caring for a patient in the postanesthesia care unit. The patient asks for a bedpan and states to the nurse, 'I feel like I need to go to the bathroom, but I can't.' Which of the following nursing interventions would be most appropriate?

Correct Answer: C

Rationale: Assessing intake and bladder distention is most appropriate, as anesthesia can delay urinary control 6-8 hours. Palpating for a full bladder and reviewing fluids (e.g., IVs) determines if retention exists, needing intervention like catheterization if distended. Waiting may work if non-distended, but assessment precedes. Immediate catheterization requires physician order post-assessment. Dismissing the feeling as universal ignores individual variation. This step ensures tailored care, preventing retention complications, per postoperative standards.

Correct Answer: C

Rationale: The commonest computer operating system is determined by widespread use across personal computers globally. 'Windows,' is correct because it dominates the desktop and laptop market, with over 70% share as of 2025 (per StatCounter data), due to its user-friendly interface and compatibility with most software. 'Linux,' is popular among developers and servers but has a niche desktop audience (under 5%). 'Android,' leads in mobile devices, not traditional computers, despite its Linux base. 'MS-DOS,' is outdated, used in the 1980s-90s, not today. Windows' prevalence in homes, offices, and education, driven by Microsoft's marketing and legacy, outstrips competitors in general computer use (excluding mobile-specific OS), making C the clear answer, supported by current industry statistics.

Correct Answer: B

Rationale: Res ipsa loquitur' (the thing speaks for itself) is a legal doctrine allowing negligence to be inferred when an incident wouldn't occur without it, aiding the plaintiff. 'Plaintiff,' is correct because it shifts the burden to the defendant to explain, as in cases like Byrne v. Boadle (1863), per tort law (e.g., Keeton). 'Defendant,' defends, not benefits. 'Court,' applies the doctrine, not uses it. 'Attorney,' represents, not proves directly. The plaintiff leverages this when evidence is scarce but negligence is obvious (e.g., a surgical tool left inside), making B the accurate answer, rooted in civil litigation principles.

Correct Answer: D

Rationale: Ease, convenience, and cost favor a drug route requiring minimal equipment or expertise. 'Oral,' is correct because it involves swallowing a pill, needing no needles or medical staff, as per pharmacoeconomics (e.g., DiPiro's Pharmacotherapy). 'Intramuscular,' requires injections, less convenient. 'Intravenous,' needs IV setup, costly and complex. 'Subcutaneous,' also involves needles, less simple. Oral administration's widespread use—cheap, self-administered, and non-invasive—makes D the standout answer, reflecting its practicality in outpatient care.

Correct Answer: A

Rationale: Fires fueled by combustibles like paper are Class A fires, best extinguished by cooling and soaking. 'Pressurized water,' is correct because it douses flames and prevents reignition, per fire safety standards (e.g., NFPA). 'Compressed gas,' (e.g., CO2) suits electrical fires (Class E), not paper. 'Liquid soap,' is ineffective and impractical. 'Graphite powder,' is not a standard extinguisher. Water's efficacy on Class A materials—wood, paper—makes A the precise answer, aligned with firefighting protocols.
