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 A
Explanation
Choice A rationale:
Assigning a client who is one day postoperative for a laparoscopic cholecystectomy to the practical nurse (PN) is appropriate. This procedure is minimally invasive, and the client is likely stable, requiring routine postoperative care such as wound assessment, pain management, and monitoring for any signs of complications.
Choice B rationale:
An older client who is one day postoperative with a colostomy for colon cancer may have complex postoperative needs, including colostomy care, monitoring for complications, and pain management. This level of care is usually within the scope of the registered nurse (RN) rather than a practical nurse (PN).
Choice C rationale:
An older adult who is scheduled for foot amputation due to diabetes complications is likely to have complex care needs, including wound care, diabetes management, and potential complications. This client would require the expertise of an RN rather than a PN.
Choice D rationale:
An adult with alcoholism, cirrhosis, and hepatic encephalopathy may have complex medical and psychosocial issues that require specialized nursing care. This client's condition is not appropriate for a practical nurse (PN) to manage, and the care should be provided by an RN or other specialized healthcare provider.
Correct Answer is B
Explanation
The correct answer is choice B. “You seem quite frightened right now.”.
Choice A rationale:
While reassuring the client that no one will hurt them is well-intentioned, it may not effectively address the client’s immediate emotional state or validate their feelings.
Choice B rationale:
Acknowledging the client’s fear helps validate their emotions and opens a pathway for further therapeutic communication. It shows empathy and understanding, which can help build trust and provide comfort.
Choice C rationale:
Telling the client they are in a safe place is reassuring, but it may not fully address the client’s immediate emotional distress or validate their feelings.
Choice D rationale:
Asking the client what they would like the nurse to do to protect them might reinforce the delusion and could potentially escalate the situation. It is more effective to acknowledge the client’s feelings and provide reassurance.
