Correct Answer: B

Rationale: The correct sequence for obtaining a clean catch urine specimen involves first cleaning the meatus to prevent contamination, then initiating voiding to catch the midstream urine. This method ensures that the sample is as uncontaminated as possible, making choice B the correct sequence. Option A is incorrect as cleaning the meatus should be done before voiding. Option C is incorrect as it does not involve catching a midstream urine sample. Option D is incorrect as it suggests catching urine throughout the entire voiding process, which may lead to contamination.

Correct Answer: A

Rationale: The correct action for the nurse to take is to gently shake the container of liquid medication before administration. Shaking the container ensures proper mixing of the medication, which is important to maintain uniformity of the dose. Transferring the medication to a medicine cup (choice B) may not be necessary for a small volume like 0.5 mL. Placing the client in a semi-Fowler's position (choice C) is not directly related to administering liquid medication orally. Verifying the dosage by measuring the liquid (choice D) is important but does not address the specific action needed to prepare the medication for administration.

Correct Answer: A

Rationale: When changing the linen on a client's bed, it is essential for the nurse to hold the linen away from their body and clothing. This practice helps prevent contamination and maintain a clean environment. Folding the linen neatly before placing it in the laundry (Choice B) is a good practice but not the immediate action required during linen changing. Wearing clean gloves while handling the linen (Choice C) is important in certain situations but may not be necessary for routine linen changing. Placing the linen directly on the floor until the new linen is in place (Choice D) is incorrect as it can lead to contamination and is not hygienic.

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: 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.
