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
Explanation
Choice A rationale:
The statement, "This medication will shorten the duration of my symptoms," is correct. Oseltamivir is an antiviral medication used to treat influenza, and it can reduce the duration of symptoms when taken early in the course of the illness.
Choice B rationale:
The statement, "This medication will prevent me from spreading the virus to others," is incorrect. While oseltamivir can help reduce the severity and duration of symptoms, it does not prevent the spread of the virus to others. Clients with influenza should still take precautions to avoid transmitting the virus to others.
Choice C rationale:
The statement, "This medication will work best if I start taking it within 48 hours of symptom onset," is correct. Oseltamivir is most effective when started within 48 hours of the onset of symptoms.
Choice D rationale:
The statement, "This medication may cause nausea and vomiting as side effects," is correct. Nausea and vomiting are potential side effects of oseltamivir, and clients should be informed about these possible adverse reactions.
Correct Answer is D
Explanation
Choice D rationale:
Taking zolpidem before bedtime is the correct information to include in the education. Zolpidem is a medication used for the short-term treatment of insomnia and should be taken immediately before going to bed to facilitate sleep onset.
Choice A rationale:
Crushing zolpidem to increase absorption is not recommended. The medication should be taken whole and not crushed or chewed.
Choice B rationale:
Storing zolpidem at room temperature is correct. Like many medications, zolpidem should be stored at a controlled room temperature, away from moisture and heat.
Choice C rationale:
Administering zolpidem with a meal is not necessary and may delay the onset of its effects. It is typically taken on an empty stomach for faster absorption.
