Correct Answer: D

Rationale: The most crucial aspect of colostomy care to teach the client is to assess the stoma for color and swelling. This is essential to detect early signs of complications such as ischemia or infection. Changing the colostomy bag daily is important but not as critical as assessing the stoma for complications. Irrigating the colostomy daily is not a standard recommendation and should be performed based on healthcare provider's instructions. While avoiding high-fiber foods may be beneficial for some individuals with a colostomy, it is not the most important aspect of care compared to monitoring the stoma for complications.

Correct Answer: B

Rationale: The most appropriate dietary recommendation for a client with chronic heart failure is to follow a low-sodium diet. This helps manage the condition by reducing fluid retention and the workload on the heart. High fluid intake can lead to fluid overload and exacerbate heart failure symptoms. While protein is important for overall health, a high-protein diet is not specifically indicated for chronic heart failure. Increasing sodium intake is contraindicated in heart failure as it can worsen fluid retention and increase the workload on the heart.

Correct Answer: B

Rationale: When taking blood pressure at the brachial artery, it is crucial to place the client's arm at the level of the heart to ensure accurate measurement. Placing the arm above or below the heart level can lead to incorrect readings. Option A, placing the arm slightly above the heart level, would result in falsely lower blood pressure readings as gravity would assist in a lower value. Option C, placing the arm at a level of comfort for the client, may not align with the standardized technique required for accurate blood pressure assessment. Option D, placing the arm below the level of the heart, would likely yield falsely higher blood pressure readings due to increased hydrostatic pressure pushing the blood against gravity.

Correct Answer: B

Rationale: The correct answer is to observe the mother breastfeeding her infant. This action is essential to ensure that the infant is feeding well and to assess maternal-infant bonding. Administering the rubella vaccine subcutaneously (Option A) is not the immediate priority in this scenario as assessing breastfeeding is more crucial. Calling the nursery for the infant's blood type result (Option C) is premature and not the next appropriate step, as it does not address the immediate needs of the newborn. Administering Vicodin one tablet for pain (Option D) is not indicated without further assessment or indication of pain, making it an incorrect choice at this time.

Correct Answer: B

Rationale: The correct answer is B because cleaning the perineal area is a task within the scope of practice for unlicensed assistive personnel (UAPs) and is crucial for preventing infections. Choice A involves a more complex task that requires a healthcare provider's assessment. Choice C involves a sterile procedure that should be performed by licensed staff. Choice D involves specific care for a client with a catheter that exceeds the UAP's scope of practice.
