Correct Answer: B

Rationale: The most crucial action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. Kinks in the tubing can lead to urine retention or obstruction, increasing the risk of infection. Changing the catheter every 72 hours is not necessary if there are no signs of infection or other issues. Cleaning the perineal area with antiseptic solution daily is important for hygiene but not the most critical action to prevent infection related to the catheter. Irrigating the catheter with normal saline every shift is not a routine practice and may increase the risk of introducing pathogens into the urinary system.

Correct Answer: B

Rationale: The correct action for the nurse to include when assessing the client's gag reflex is to place a tongue blade on the back half of the tongue. This method effectively tests the gag reflex without causing discomfort. Choice A is incorrect because offering small sips of water through a straw does not assess the gag reflex. Choice C is incorrect as using a penlight to observe the back of the oral cavity does not directly assess the gag reflex. Choice D is incorrect since auscultating breath sounds after the client swallows does not evaluate the gag reflex.

Correct Answer: A

Rationale: The Romberg test is utilized to assess the client's balance and proprioception by having them stand with their eyes closed. This test helps evaluate sensory ataxia, a condition where an individual's balance is affected due to impaired sensory input. Deep tendon reflexes (Choice B) are assessed by tapping a tendon with a reflex hammer to evaluate the integrity of the spinal cord and peripheral nerves; this is not directly related to balance assessment. The Mini-Mental State Examination (Choice C) is a cognitive screening tool used to assess cognitive impairment or dementia, not balance. The Babinski reflex (Choice D) is elicited by stroking the sole of the foot to assess neurologic function, particularly in the corticospinal tract, and is not specific to balance evaluation.

Correct Answer: A

Rationale: Reassessing the client is crucial to identify the reasons for inadequate pain relief. This action allows the nurse to gather more information, evaluate the current pain management interventions, and make necessary adjustments to the care plan. Waiting for the pain to lessen without taking action delays appropriate pain management. Changing the plan of care without reassessment may lead to ineffective interventions. Teaching the client about the plan of care should be based on a reassessment of the current pain relief status to ensure tailored and effective pain management strategies.

Correct Answer: A

Rationale: The correct answer is to Evacuate the client (Choice A). In the event of a fire, the safety of the client is the top priority. The RACE (Rescue, Alarm, Contain, Extinguish) mnemonic is used in fire emergencies. The first step is to Rescue or Evacuate the individual from immediate danger. Attempting to extinguish the fire (Choice B) may endanger both the client and the nurse. Calling the fire department (Choice C) is important but should come after ensuring the client's safety. Closing the door to contain the fire (Choice D) is not appropriate in this scenario because the priority is to remove the client from harm's way.
