Answer to Question 1

A
Foscarnet frequently causes hypocalcemia and other electrolyte and mineral imbalances. Pares-thesias, numbness in the extremities, and perioral tingling can indicate hypocalcemia, so a calcium level should be drawn. These are not signs of foscarnet overdose. Nephrotoxicity may occur, but these are not signs of renal complications, so a creatinine clearance is not indicated. If nephrotoxicity occurs, prehydration with IV saline is indicated to reduce the risk of renal injury.

Answer to Question 2

C
Ganciclovir ocular implants must be replaced every 5 to 8 months and do not remain in place permanently. It is correct that vision may be blurred for 2 to 4 weeks after placement of the im-plant, that placement is an outpatient procedure, and that the implant will slow progression of CMV retinitis.
