Correct Answer: D

Rationale: The correct technique for a four-point crutch gait involves moving the crutches forward, then moving one leg at a time. This method provides stability and support by alternating movement between the crutches and legs. Choice A is incorrect because bearing weight on both legs simultaneously is not the correct method for a four-point gait. Choice B is incorrect as moving the crutches and weak leg together does not provide the required stability. Choice C is incorrect as advancing the crutches and strong leg together does not promote the alternating movement needed for a four-point gait.

Correct Answer: C

Rationale: Infiltration occurs when the IV fluid leaks into the surrounding tissue instead of entering the bloodstream properly. Skin blanching, swelling, and coolness at the IV site are typical signs of infiltration. Purulent exudate (choice A) is associated with infection, warmth (choice B) can indicate phlebitis, and bleeding (choice D) may occur if the IV catheter punctures a blood vessel.

Correct Answer: D

Rationale: The correct answer is D: Bradycardia. Beta-blockers are known to decrease heart rate, which can lead to bradycardia. This is a common side effect that nurses should monitor for in clients taking beta-blockers. Choices A, B, and C are incorrect because increased appetite, dry mouth, nausea, and vomiting are not typical side effects associated with beta-blockers. Therefore, the nurse should focus on monitoring for bradycardia in this client.

Correct Answer: B

Rationale: The correct answer is to continue monitoring the patient as instructed. This is crucial to assess the patient's condition and response to initial interventions. Administering IV fluids or preparing for transfer to the ICU should only be done based on further assessment or explicit orders from the healthcare provider. Notifying the nurse manager, as suggested in choice A, without further assessment or intervention could delay immediate patient care and management.

Correct Answer: B

Rationale: Passive ROM exercises should begin as soon as the patient loses the ability to move the extremity or joint. Initiating passive ROM early helps prevent contractures and maintain joint function. Choice A is incorrect because delaying passive ROM until after the acute phase may lead to irreversible contractures. Choice C is not the best option as waiting until the patient enters the rehab unit delays crucial preventive measures. Choice D is incorrect as passive ROM should not be based on patient requests but on clinical indications and best practices.
