Extract:
Question 1 of 5
The nurse is caring for a client with atrial fibrillation who receives a prescription for warfarin. The international normalized ratio (INR) is 2.8. Which action should the nurse take?
Correct Answer: D
Rationale: An INR of 2.8 is therapeutic for atrial fibrillation (2.0-3.0), but notifying the provider (
D) ensures dose stability per protocol. Giving the dose (
A) is likely safe but not prioritized. Repeat sampling (
B) is unnecessary unless error is suspected. Bleeding monitoring (
C) is routine, not primary.
Question 2 of 5
A client is scheduled for a spiral computed tomography (CT) scan with contrast to evaluate for pulmonary embolism. Which information in the client’s history requires follow-up by the nurse?
Correct Answer: B
Rationale: Metformin (
B) risks lactic acidosis with contrast dye due to potential renal impairment. Follow-up ensures temporary discontinuation (e.g., 48 hours post-procedure). Prior CT (
A) is irrelevant unless complications occurred. Sobriety (
C) and metal prosthesis (
D) do not affect contrast safety, though metal may impact image quality.
Question 3 of 5
A client with chronic kidney disease (CKD) is receiving calcium acetate 667 mg PO. A decrease in which blood value indicates to the nurse that the medication is having the desired effect?
Correct Answer: C
Rationale: Calcium acetate binds dietary phosphate in CKD, reducing serum phosphate levels (
C), the desired effect. It does not lower potassium (
A) or pH (
D). It may increase calcium (
B), but this is not the goal.
Question 4 of 5
When administering zolpidem to an older client, which computer documentation indicates that the desired outcome has been achieved?
Correct Answer: D
Rationale: This question is identical to Question 15. Zolpidem treats insomnia; sleeping soundly (
D) indicates efficacy. Incontinence (
A), concentration (
B), and outbursts (
C) are unrelated. Note: Duplicate question; consider removing.
Question 5 of 5
A client with narcolepsy receives a new prescription for methylphenidate. Prior to administration of the medication, the nurse should review the medical record for which condition?
Correct Answer: B
Rationale: Methylphenidate increases blood pressure/heart rate, risking exacerbation of hypertension (
B). Hypercholesterolemia (
A), diabetes (
C), and bronchitis (
D) are not primary concerns.
