NCLEX Pharmacology Questions Questions
Extract:
Question 1 of 5
The client diagnosed with methicillin-resistant Staphylococcus aureus (MRSA) is receiving the aminoglycoside antibiotic vancomycin. Peak and trough levels are ordered for the dose the nurse is administering. Which priority intervention should the nurse implement?
Correct Answer: C
Rationale: Trough levels must be drawn before the next vancomycin dose to ensure therapeutic levels and avoid toxicity; this is the priority. Diarrhea, peak levels, or culture reports are secondary.
Question 2 of 5
The nurse is administering carbidopa/levodopa (Sinemet) to the client. Which assessment should the nurse perform to determine if the medication is effective?
Correct Answer: B
Rationale: Carbidopa/levodopa reduces Parkinson’s symptoms like cogwheel rigidity; decreased cogwheel movements indicate effectiveness. Strength, levels, or BP are less specific.
Question 3 of 5
The client is receiving a continuous heparin drip, 20,000 units/500 mL D5W, at 23 mL/min. How many units of heparin is the client receiving an hour?
Correct Answer: 55200
Rationale: Concentration: 20,000 units / 500 mL = 40 units/mL. Rate: 23 mL/min x 60 min/hr = 1,380 mL/hr. Dose: 1,380 mL/hr x 40 units/mL = 55,200 units/hr.
Question 4 of 5
The client diagnosed with Parkinson's disease is taking levodopa (L-dopa) and is experiencing an 'on/off' effect. Which action should the nurse take regarding this medication?
Correct Answer: A
Rationale: The on/off effect is a known levodopa issue; documenting monitors progression without immediate action. Increasing dose, death discussions, or calling it desired are incorrect.
Question 5 of 5
The HCP has ordered an intramuscular antibiotic. After reconstituting the medication, the clinic nurse must administer 4.8 mL of the medication. Which action should the nurse implement first when administering this medication?
Correct Answer: D
Rationale: IM injections >3 mL should be divided; 2.4 mL in each hip (gluteal) ensures safe absorption. Notifying HCP, single-site injection, or discarding are incorrect.
