Question 1 of 5

The healthcare provider prescribes filgrastim 5 mog/kg/day subcutaneously for a client who weighs 132 pounds and has just completed chemotherapy. The medication is available in 480 mcg/0.8 mL. How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

Correct Answer: 0.5

Rationale: Weight: 132 / 2.2 = 60 kg. Dose: 5 mcg/kg/day × 60 = 300 mcg/day. Concentration: 480 mcg / 0.8 mL = 600 mcg/mL. Volume: 300 / 600 = 0.5 mL. [Note: Document states 500.0 mL, likely a typo; correct calculation yields 0.5 mL.]

Question 2 of 5

The healthcare provider prescribes liraglutide 1.2 mg subcutaneously daily for a client with type 2 diabetes mellitus. The liraglutide Pen contains 18 mg of liraglutide and will deliver doses of 0.6 mg, 1.2 mg, or 1.8 mg. When teaching the client about the use of the liraglutide Pen, how many doses should the nurse tell the client is available in each Pen? (Enter the numerical value only.)

Correct Answer: 2

Rationale:
Total dose = 2000 mg amoxicillin + 125 mg clavulanate. Tablet strength = 1000 mg/62.5 mg. Tablets = (2000 + 125) / (1000 + 62.5) = 2 tablets.
