Pharmacology
1. The nurse prepares to administer digoxin 0.01 mg/kg PO to a 2-month-old
infant. The infant weighs 5 kg. The sleeping infant's apical pulse is 70 bpm. The
nurse takes which most appropriate action?
a) Administer the medication as prescribed
b) Wake the infant and recheck the pulse
c) Withhold the medication and notify the health care provider immediately
d) Administer half the dose and recheck in 30 minutes
*Rationale: A normal apical pulse for an infant is 100-170 bpm. A pulse of 70 bpm is
bradycardic, and digoxin should be withheld. The nurse should notify the provider
before administering any dose. Digoxin is used to improve the strength and efficiency of
the heart, but toxicity can occur, especially with bradycardia .*
2. The nurse provides care for a client diagnosed with Hodgkin's disease. The
client received cyclophosphamide. Which laboratory value does the nurse report
to the healthcare provider?
a) White blood cells 5,000/mm³
b) Hemoglobin 12 g/dL
c) Platelets 40,000/mm³
d) Potassium 4.2 mEq/L
*Rationale: A normal platelet count ranges from 150,000 to 450,000/mm³.
Cyclophosphamide is an alkylating agent that can cause bone marrow suppression. A
platelet count of 40,000/mm³ indicates severe thrombocytopenia and places the client
at risk for bleeding, requiring immediate reporting .*
3. The nurse reviews laboratory reports for a client receiving digoxin and
furosemide. Which laboratory values most concern the nurse?
