Extract:
Question 1 of 5
The nurse is caring for a client with the following arterial blood gas (ABG) results: pH 7.32, PaCO2 33 mmHg, Pa02 88 mmHg, HCO3 16 mEg/L. The nurse would Interpret these results as:
Correct Answer: D
Rationale: The low pH (7.32) and low HCO3 (16 mEq/L) indicate metabolic acidosis. The low PaCO2 (33 mmHg) suggests respiratory compensation by blowing off CO2, but since the pH is still acidic, it is partially compensated.
Question 2 of 5
The nurse is caring for a client whose arterial blood gas reveals fully compensated metabolic acidosis. Which results are consistent with this finding?
Correct Answer: A
Rationale: Normal pH (7.36), low HCO3 (16 mEq/L), and low PaCO2 (27 mmHg) indicate fully compensated metabolic acidosis with respiratory compensation.
Question 3 of 5
The physician orders 500 mg PO of medication. The Medication is supplied as a suspension 125 mg/5mL. How many mL will the nurse administer for one dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: The dose is 500 mg, and the suspension is 125 mg/5 mL. Proportion: 125 mg / 5 mL = 500 mg / x mL. Solving gives x = 20 mL.
Question 4 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 5 of 5
The nurse is to begin a nitroglycerin infusion for a client diagnosed with an anterior wall myocardial infarction. Which assessment finding should the nurse report to the provider immediately?
Correct Answer: D
Rationale: A blood pressure of 90/50 mmHg is significantly low and could indicate hypotension, a known side effect of nitroglycerin infusion. This can compromise perfusion to vital organs and may require adjustment or discontinuation of the infusion, making it the most urgent finding to report.
