Question 2 of 5
A patient will be receiving monthly injections of cyanocobalamin. The dose is 100 mcg/month IM. The medication is available in a strength of 1000 mcg/mL. Identify how many milliliters the nurse will draw up into the syringe. (Record answer using one decimal place.)
Correct Answer: 0.1 mL
Rationale: 1000 mcg : 1 mL :: 100 mcg : x mL. (1000 ?? x) = (1 ?? 100); 1000x = 100; x = 0.1 mL.

If not recognized and treated, these symptoms can progress to impairment of renal function and osteoporosis. The other options listed are not signs of vitamin D toxicity.
