Question 13

The amount to administer is _____.
Ordered: Cogentin 0.5 mg IV daily
On hand: Cogentin 1 mg/mL

Accepted Answer

H = 1 mg; Q = 1 mL; D = 0.5 mg
 11eeb0a8_7362_7340_be9b_bfc8cc17ed16_TB10476_00 A = 0.5 * 1 mL 
 
 A = 0.5 mL 
 
 The ordered dose is half the dose on hand, so 0.5 mL is reasonable.

Question 14

Calculate the amount to administer: _____.
Ordered: Chloroquine hydrochloride 300 mg IM daily
On hand: Chloroquine hydrochloride 200 mg/mL

Accepted Answer

H = 200 mg; Q = 1 mL; D = 300 mg 
 11eeb0a8_7362_9a51_be9b_5b8e1d5f6019_TB10476_00 A = 1.5 * 1 mL 
 
 A = 1.5 mL 
 
 The ordered dose is 1.5 times the dose on hand and 1 mL * 1.5 = 1.5 mL, so the answer is reasonable.

Question 15

Calculate the amount to administer using a tuberculin syringe: _____.
Ordered: Darbepoetin Alfa 12.5 mcg subcut weekly
On hand: See label

Accepted Answer

H = 40 mcg; Q = 1 mL; D = 12.5 mcg 
 11eeb0a8_7362_9a53_be9b_69afa261097a_TB10476_00 A = 0.3125 * 1 mL 
 
 A = 0.3125, rounded to 0.31 mL 
 
 Amounts less than 1 mL are rounded to the nearest hundredth.
 
 The ordered dose is a little less than a third of the dose on hand, so the answer is reasonable.

Question 16

Calculate the amount to administer: _____.
Ordered: Filgrastim 120 mcg subcut daily
See label for available medication

Accepted Answer

H = 300 mcg; Q = 1 mL; D = 120 mcg 
 11eeb0a8_7362_c165_be9b_e78d1fa3d5b7_TB10476_00 A = 0.4 * 1 mL
 
 A = 0.4 mL 
 
 The ordered dose is a little more than a third of the dose on hand, so it is reasonable.
