Correct Answer is D
Explanation
A. Identify effective pain relief measures is important but not the first step in assessing pain quality. The nurse must first assess the pain itself before determining what interventions are effective.
B. Provide a numeric pain scale is commonly used to assess the intensity of pain, but it does not address the quality of pain. The numeric scale helps measure the severity, but it does not capture how the pain feels.
C. Observe body language and movement can provide clues about pain but does not give a comprehensive understanding of the pain's quality. While useful for assessing nonverbal clients, this approach alone does not provide detailed information about the pain experience.
D. Ask the client to describe the pain is the best approach for assessing the quality of pain. By asking the client to describe the pain, the nurse can gather information about its characteristics, such as sharp, dull, burning, or aching, which provides insight into the nature of the pain and helps guide appropriate interventions.
Correct Answer is ["4"]
Explanation
Convert mg to mcg: 1 mg = 1000 mcg, so 0.5 mg = 0.5 x 1000 = 500 mcg
Divide the desired dose by the tablet strength: 500 mcg / 125 mcg/tablet = 4 tablets
So, the nurse should administer 4 tablets.
