When administering oxygen therapy, what should the nurse prioritize to ensure the safety of the client?

Correct Answer: B

Rationale: Monitoring oxygen saturation levels (B) via pulse oximetry is the priority in oxygen therapy safety, as it directly assesses oxygenation effectiveness, ensuring the client's needs are met (target SpO2 typically 92-98%). Respiratory rate (A) is a vital sign but doesn't quantify oxygen delivery. Dyspnea (C) is subjective and less precise than objective SpO2 readings. Adjusting flow rate (D) depends on saturation data, making it secondary. Continuous or frequent SpO2 monitoring detects hypoxemia or hyperoxia early, guiding interventions to prevent complications like respiratory depression or tissue damage, a cornerstone of safe oxygen administration per nursing protocols.

Correct Answer: B

Rationale: Itching is a frequent complaint in end-stage renal failure due to uremia, where accumulated waste products irritate skin nerves a hallmark of kidney dysfunction. Weight loss, tinnitus, or bruising may occur but aren't as universally tied to this stage. Nurses address this symptom with skin care and dialysis adjustments, educating clients on its cause, improving quality of life amid chronic illness.

Correct Answer: D

Rationale: Small, frequent meals compensate for limited intestinal absorption in AIDS-related wasting syndrome, delivering nutrients gradually to maximize uptake despite diarrhea or malabsorption, common in advanced HIV. Cooking foods, yogurt, or fluids help but don't address volume capacity directly. Nurses implement this strategy to combat weight loss, ensuring energy and protein needs are met, supporting immune function and strength.

Correct Answer: A

Rationale: For a 2-year-old, pulling the ear down and back straightens the canal for Cortisporin drops, ensuring medication reaches the infection site standard for children under 3. Up-and-back suits adults; straight out or undisturbed risks poor delivery. Nurses use this technique, teaching parents for home use, optimizing treatment efficacy.

Correct Answer: C

Rationale: Coughing and deep breathing prevent pneumonia complications like atelectasis or secretion buildup, promoting lung expansion flat beds, fluid limits, or prone positioning worsen oxygenation. Nurses assist this, enhancing clearance, reducing infection spread or respiratory distress in recovery.
