A client with chronic kidney disease receives a prescription for darbepoetin alfa 40 mcg subcutaneous every 7 days.
The darbepoetin alfa vial is labeled, "60 mcg/mL." How many mL should the nurse administer? round to the nearest tenth.
0.7 mL.
1.0 mL.
1.3 mL.
1.7 mL.
The Correct Answer is A
Step 1 is to determine the amount of darbepoetin alfa in each mL of solution. The vial is labeled as “60 mcg/mL”, which means each mL contains 60 mcg of darbepoetin alfa.
Step 2 is to calculate the volume of the solution that contains 40 mcg of darbepoetin alfa. This can be done by dividing the prescribed dosage by the concentration of the solution. So, the volume is 40 mcg ÷ 60 mcg/mL = 0.67 mL.
However, since we need to round to the nearest tenth, the volume becomes 0.7 mL.
So, the correct answer is, after analysing all choices, the nurse should administer 0.7 mL of the darbepoetin alfa solution.

Correct Answer is C
Explanation
The correct answer is choicec. Administer prescribed stool softener.
Choice A rationale:
Administering prescribed PRN sleep medications can help the client rest, but it is not the highest priority. Managing pain and preventing complications from the laceration are more critical.
Choice B rationale:
Encouraging the use of prescribed analgesic perineal sprays can help manage pain and promote healing, but it is not as crucial as preventing constipation, which can cause significant discomfort and complications.
Choice C rationale:
Administering prescribed stool softeners is the highest priority because a fourth-degree laceration involves the anal sphincter and rectal mucosa.Preventing constipation is essential to avoid straining during bowel movements, which can cause pain and disrupt the healing process.
Choice D rationale:
Encouraging breastfeeding to promote uterine involution is important for postpartum recovery, but it is not directly related to the care of a fourth-degree laceration. Managing pain and preventing complications from the laceration take precedence.
Correct Answer is D
Explanation
Choice A rationale:
Observing body language and movement is a valuable method for assessing pain, but it may not provide a comprehensive understanding of the client's pain experience. Clients may have different ways of expressing pain, and verbal communication should also be considered.
Choice B rationale:
Identifying effective pain relief measures is relevant but does not assess the quality of the pain itself. It focuses on pain management rather than pain assessment.
Choice C rationale:
Providing a numeric pain scale is a useful tool for quantifying pain intensity, but it does not assess the quality of pain, which is essential for understanding the nature of migraine headaches.
Choice D rationale:
Asking the client to describe the pain is the most appropriate approach for assessing the quality of pain. It allows the client to express the characteristics of the pain, such as its location, intensity, duration, and any associated symptoms, which can aid in diagnosis and treatment planning.
