Correct Answer: C

Rationale: The correct answer is C. Using a clean technique for inserting a urinary catheter increases the risk for healthcare-associated infections. Invasive procedures like catheter insertion require a sterile technique to prevent introducing pathogens into the urinary tract. Choices A and B demonstrate appropriate infection control measures by emphasizing the use of sterile or aseptic techniques. Choice D represents an incorrect technique that can lead to the introduction of bacteria from the rectum into the urinary tract, potentially causing infections.

Correct Answer: A

Rationale: Correct answer: When a patient with a left arm fracture reports severe pain unrelieved by medication, the nurse should assess for compartment syndrome. Compartment syndrome is a condition where increased pressure within a muscle compartment compromises circulation and can lead to tissue damage. It is a surgical emergency that requires immediate intervention. Choice B is incorrect because simply increasing pain medication without identifying the cause of the unrelieved pain may mask symptoms of a serious issue like compartment syndrome. Choice C is incorrect as surgery would only be necessary if compartment syndrome is confirmed. Choice D is incorrect as administering a sedative does not address the underlying issue of unrelieved pain and may delay appropriate treatment.

Correct Answer: B

Rationale: The best response for the nurse is to ask the patient for permission to secure the jewelry safely. Hospital policy typically requires jewelry to be secured or removed to prevent interference during surgery. Proceeding with the surgery without addressing the issue or taping the jewelry to the patient's body are not safe practices and can lead to complications during the procedure. Directing the patient to remove the jewelry without exploring alternative solutions is not patient-centered care and may create unnecessary tension.

Correct Answer: B

Rationale: Confirming the patient's allergies before administering medications is crucial for patient safety as it helps prevent adverse reactions. Checking the patient's wristband is important for identification but may not directly impact medication safety. Documenting medications after administration is necessary but does not primarily promote safety during administration. Preparing medications at the medication cart, rather than the nurse's station, is preferred to ensure accuracy and proper medication handling, but it is not directly related to confirming allergies for safety.

Correct Answer: B

Rationale: The correct answer is to reposition the patient every 2 hours. Repositioning helps prevent the worsening of pressure ulcers by relieving pressure on affected areas and promoting blood circulation, which aids in healing. Applying a dressing (choice A) is important but not the priority compared to repositioning. Providing pain medication (choice C) is essential for comfort but does not address the root cause of the pressure ulcer. Cleaning the ulcer with normal saline (choice D) is part of wound care but does not take precedence over repositioning to prevent further tissue damage.
