Pharmacology on NCLEX Questions
Extract:
Question 1 of 5
The client on bedrest is receiving enoxaparin (Lovenox), a low molecular weight heparin. Which anatomical site is recommended for administering this medication?
Correct Answer: D
Rationale: Enoxaparin is injected subcutaneously in the anterolateral abdomen for optimal absorption and minimal bruising, per manufacturer guidelines.
Question 2 of 5
A client with atrial fibrillation is receiving digoxin (Lanoxin). Which of these assessments is most important for the nurse to perform?
Correct Answer: B
Rationale: Measure apical pulse prior to administration. Digitoxin decreases conduction velocity through the AV node and prolongs the refractory period. If the apical heart rate is less than 60 beats/minute, withhold the drug. The apical pulse should be taken with a stethoscope so that there will be no mistake about what the heart rate actually is.
Question 3 of 5
The client with coronary artery disease is prescribed one (1) baby aspirin a day. Which instructions should the nurse provide the client concerning this medication?
Correct Answer: D
Rationale: Dark, tarry stools suggest GI bleeding, a serious aspirin side effect, requiring HCP notification. Empty stomach, Tylenol, or joint pain are less critical.
Question 4 of 5
The client is to receive 3,000 mg of medication daily in a divided dose every eight (8) hours. The medication comes 500 mg per tablet. How many tablets will the nurse administer at each dose?
Correct Answer: 2
Rationale: Daily dose: 3,000 mg / 3 doses (every 8 hr) = 1,000 mg/dose. Tablets: 1,000 mg / 500 mg/tablet = 2 tablets per dose.
Question 5 of 5
The client in the intensive care department is receiving 2 mcg/kg/min of dopamine, an inotropic vasopressor. Which intervention should the nurse include in the plan of care?
Correct Answer: C
Rationale: Dopamine affects renal perfusion; hourly urine output via urometer monitors efficacy and prevents toxicity. BP, pulses, or light exposure are less critical.
