How can a nurse prevent complications while providing oxygen therapy to a patient?

Correct Answer: B

Rationale: Monitoring oxygen saturation regularly prevents complications in oxygen therapy by ensuring levels stay within a safe range (e.g., 92-98% for most), avoiding hypoxia or hyperoxia. High flow rates without monitoring risk toxicity, especially in COPD patients. A tight mask causes discomfort and skin breakdown, not prevention. Limiting fluids is unrelated hydration supports recovery. Nurses use pulse oximetry to adjust delivery, balancing oxygenation with safety, and watch for signs like confusion or cyanosis, making this a proactive, essential step in respiratory care.

Correct Answer: C

Rationale: A sitz bath cleanses the perineal area and provides pain relief for hemorrhoid patients by soaking in warm water, reducing swelling and soothing irritation while maintaining hygiene. Relaxation might occur, but it's secondary to therapeutic effects. Joint mobility isn't affected it's localized care. Cooling body temperature requires cold, not warm, water sitz baths warm. Nurses offer this to ease discomfort and promote healing, often post-surgery or for chronic cases, a targeted comfort measure.

Correct Answer: C

Rationale: Cleansing the perineal area from front to back after toileting prevents UTIs in female patients by keeping fecal bacteria away from the urethra, a short pathway prone to infection. Holding urine fosters bacterial growth, increasing risk. Back-to-front wiping introduces pathogens, the opposite of prevention. Limiting fluids concentrates urine, encouraging infection, not deterring it hydration flushes bacteria. Nurses teach and reinforce this technique, especially in dependent care, to minimize UTI incidence, a common yet avoidable issue.

Correct Answer: A

Rationale: A warm compress provides pain relief for muscle stiffness by increasing blood flow, relaxing tense fibers, and easing discomfort from spasms or immobility. Sweating might occur but isn't the goal relief is. Lowering temperature requires cold, not warmth heat does the opposite. Promoting contraction contradicts relaxation; it loosens, not tightens. Nurses apply it to soothe and improve flexibility, a targeted comfort measure leveraging heat's therapeutic effects on musculoskeletal pain.

Correct Answer: D

Rationale: Providing assistance with nail care as needed ensures proper hygiene for a mobility-impaired patient by trimming or cleaning nails to prevent overgrowth or infection, tailored to their ability. Avoiding care risks ingrown nails or dirt buildup, inviting infection, not preventing it. Yearly hygiene is neglect monthly or as needed is standard. Doing it fully saves time but may not empower support balances help with autonomy. Nurses use clippers or files, aiding grooming safely, a detail enhancing comfort and health.
