Correct Answer: C

Rationale: To administer 7.5 mg of metolazone (Zaroxolyn), the LPN/LVN should plan to give 1 1/2 tablets since each tablet contains 5 mg. Choice A (1/2 tablet) would not provide the full prescribed dose. Choice B (1 tablet) would only deliver 5 mg, which is less than the prescribed dose. Choice D (2 tablets) would exceed the prescribed dose, resulting in 10 mg instead of the required 7.5 mg. Therefore, the correct answer is to administer 1 1/2 tablets to achieve the prescribed 7.5 mg.

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: In paralytic ileus, bowel sounds are typically absent or significantly reduced due to decreased motility of the intestines. This absence of bowel sounds is a key characteristic used in diagnosing paralytic ileus. Hyperactive bowel sounds are not expected in this condition as there is a lack of normal peristalsis. Normal bowel sounds would not be present in paralytic ileus, and hypoactive bowel sounds, which indicate decreased bowel motility, are more commonly associated with conditions like postoperative ileus or constipation, rather than paralytic ileus.

Correct Answer: A

Rationale: Performing hand hygiene is essential before any direct patient care procedure to prevent the spread of infection. Proper hand hygiene helps reduce the risk of introducing harmful microorganisms to the client, especially when dealing with a procedure like tracheostomy care. Identifying the client, preparing the sterile field, and donning sterile gloves are all important steps in tracheostomy care, but hand hygiene precedes them to maintain asepsis and ensure patient safety.

Correct Answer: C

Rationale: The correct answer is C. Offering a variety of foods in small portions is appropriate for a 2-year-old toddler as it helps provide balanced nutrition and allows the child to explore different tastes and textures. Choice A is incorrect because whole milk is recommended up to 2 years old, not until 3 years old. Choice B is incorrect as excessive juice intake can lead to excessive sugar consumption and is not recommended. Choice D is incorrect as popcorn may pose a choking hazard for toddlers and is not a suitable alternative to sweets.
