Correct Answer: B

Question 2 of 5
A client with an acute stroke must receive Alteplase 0.9 mg/kg (maximum dose 90 mg) over 60 minutes. The client weighs 220 pounds. How many mg should the client receive? (Round to the nearest tenth, do not use trailing zeros)
Correct Answer: A
Rationale: Weight is 99.7664 kg (220 lbs x 0.453592). Dose is 0.9 mg/kg x 99.7664 kg = 89.8 mg, which is below the maximum of 90 mg.
Question 3 of 5
A nurse is providing teaching to a client newly diagnosed with Parkinson's disease who is prescribed carbidopa/levodopa. What should be included in client teaching?
Correct Answer: C
Rationale: Orthostatic hypotension is a common side effect of carbidopa/levodopa. Educating the client to change positions slowly helps prevent dizziness or falls, which is critical for safety.

Correct Answer: B
Rationale: Low pH (7.17) and high PaCO2 (47 mmHg) indicate respiratory acidosis, with elevated HCO3 (29 mEq/L) showing partial compensation.
