The healthcare provider prescribes cyanocobalamin 100 mcg IM every 3 days for a client with pernicious anemia. The vial is labeled, "Cyanocobalamin Injection USP 1 mg/mL." How many mL(s) should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.1"]
Calculation:
Desired dose = 100 mcg.
- Available concentration and convert to matching units.
Available concentration = 1 mg/mL
Convert mg to mcg:
1 mg = 1000 mcg
Available concentration = 1000 mcg/mL.
- Calculate the volume to administer in milliliters (mL).
Volume to administer (mL) = Desired dose (mcg) / Available concentration (mcg/mL)
= 100 mcg / 1000 mcg/mL
= 0.1 mL.

Correct Answer is D
Explanation
A. Determine if the full course of the initial prescription of medication was taken: This information alone does not address the immediate concern of severe watery diarrhea, which may indicate a serious complication rather than incomplete treatment.
B. Offer instructions about the use of an over-the-counter (OTC) antidiarrheal medication: OTC antidiarrheals can be harmful if the diarrhea is caused by a serious infection such as Clostridioides difficile. Suppressing diarrhea without evaluation can delay appropriate treatment and worsen the condition.
C. Advise that the infection has returned and additional medication will be needed: Assuming a recurrent infection without diagnostic evidence risks inappropriate treatment. The diarrhea may be due to antibiotic-associated colitis or other causes unrelated to infection recurrence.
D. Explain that the diarrhea may be an adverse effect that requires further evaluation: Severe watery diarrhea occurring after antibiotic use can indicate a serious adverse effect like C. difficile colitis. Prompt recognition and medical evaluation are essential to prevent complications and ensure proper management.
Correct Answer is ["28"]
Explanation
Calculation:
- Identify the total volume to infuse and convert to milliliters (mL).
Total volume = 1 liter
1L = 1000 mL
Total volume (mL) = 1000 mL.
- Total infusion time and convert to minutes.
Infusion time = 12 hours
= 12 hours x 60 minutes/hour
= 720 minutes.
Drip factor of the IV tubing = 20 gtt/mL.
- Calculate the infusion rate in drops per minute (gtt/min).
Infusion rate (gtt/min) = (Total volume (mL) x Drip factor (gtt/mL)) / Total time (min)
= (1000 mL x 20 gtt/mL) / 720 min
= 20000 gtt / 720 min
= 27.777... gtt/min.
- Round to the nearest whole number
= 28 gtt/min.
