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 ["B","C","D","E"]
Explanation
The correct answers are Choices B, C, D, and E.
Choice A rationale: Dentures should remain in place to preserve facial structure and dignity. Removing them may cause facial collapse, distressing the family during viewing and violating postmortem presentation standards.
Choice B rationale: Gently closing the eyes prevents ocular drying and maintains a peaceful appearance. If eyelids resist closure, moistened cotton balls may be used temporarily to assist with natural positioning.
Choice C rationale: Placing a small pillow under the head elevates it, preventing blood pooling and facial discoloration due to livor mortis. It supports a natural, respectful presentation for family viewing.
Choice D rationale: Applying a body shroud ensures hygienic containment and visual dignity. It’s standard practice before transport and aligns with institutional protocols for respectful postmortem care.
Choice E rationale: Removing resuscitation equipment reduces trauma triggers for the family, restores environmental calm, and supports emotional closure. It also complies with facility standards for postmortem room preparation.
Correct Answer is ["30"]
Explanation
The correct answer is 30 mL/hour.
Step 1 is to calculate the total amount of norepinephrine in the IV bag: 4 mg norepinephrine ÷ 1000 mL = 0.004 mg/mL
Step 2 is to convert the patient's weight from pounds to kilograms: 176 pounds ÷ 2.2 = 80 kilograms
Step 3 is to calculate the total amount of norepinephrine the patient will receive per minute: 2 mcg/min × 60 min = 120 mcg/min
Step 4 is to convert micrograms (mcg) to milligrams (mg): 120 mcg ÷ 1000 = 0.12 mg
Step 5 is to calculate the total volume of norepinephrine needed per hour: 0.12 mg ÷ 0.004 mg/mL = 30 mL/hour
Therefore, the nurse should program the infusion pump to deliver 30 mL/hour.
