Correct Answer: B

Rationale: Aspirating residual volume every 4 hours ensures the client tolerates feedings and prevents overfeeding or aspiration. Tubing should be changed every 24 hours, flushing requires 30 mL every 4-6 hours, and formula should be at room temperature. Bolus feeding is inappropriate for continuous feedings.

Correct Answer: C

Rationale: Notifying the provider ensures the client receives clarification from the responsible clinician, ensuring informed consent. Brochures may not suffice, an incident report is inappropriate, the nurse should not explain the procedure, and a family meeting is unrelated to consent clarification.

Correct Answer: C

Rationale: Discarding the needle in a puncture-proof container prevents needlestick injuries and ensures safe disposal. Removing the needle is unnecessary, recapping risks injury, placing it on the table is unsafe, and cleaning the site post-injection is unnecessary.

Correct Answer: D

Rationale: Applying lotion to soften calluses, avoiding between toes, prevents infection in diabetic clients. Soaking softens skin but risks infection, corn pads require careful use, OTC medications are unsafe, and trimming corns with a razor risks injury and infection.

Correct Answer: C

Rationale: Ensuring the client is free of metal objects prevents interference with X-ray images during an intravenous pyelogram. Bowel cleansing is not routine, pain monitoring is not specific to preparation, and IV contrast is used, not oral. Applying a warm compress is unnecessary and unrelated.
