ATI NCLEX-RN Practice Questions Questions
Extract:
Question 1 of 5
A male client receives 10 U of regular human insulin SC at 9:00 AM. The nurse would expect peak action from this injection to occur at:
Correct Answer: C
Rationale: Regular insulin peaks 2-4 hours after administration, so 12 noon is the expected peak time for a 9:00 AM dose.
Question 2 of 5
The client is diagnosed with Bell’s palsy. Which intervention should the nurse implement to protect the client’s affected eye?
Correct Answer: A
Rationale: Bell’s palsy causes facial paralysis, impairing eye closure and risking corneal damage. An eye patch at night protects the eye from drying and injury. Corticosteroids reduce inflammation, blinking is encouraged, and antibiotics are not indicated.
Question 3 of 5
When the nurse is evaluating lab data for a client 18-24 hours after a major thermal burn, the expected physiological changes would include which of the following?
Correct Answer: D
Rationale: Hematocrit is elevated due to hemoconcentration from hypovolemia. Sodium, calcium, and protein levels are typically decreased due to losses into edema fluid or increased capillary permeability.
Question 4 of 5
The physician has prescribed Cobex (cyanocobalamin) for a client following a gastric resection. Which lab result indicates that the medication is having its intended effect?
Correct Answer: B
Rationale: Cyanocobalamin (vitamin B12) treats pernicious anemia post-gastric resection by improving red blood cell production, reflected by a normal hemoglobin (Hgb) level of 14.2 g/dL.
Question 5 of 5
The nurse is caring for a client with scalding burns across the face, neck, upper half of the anterior chest, and entire right arm.
Correct Answer: 32
Rationale: Rule of nines: face (4.5%), neck (4.5%), upper half anterior chest (9%), right arm (9%) = 4.5 + 4.5 + 9 + 9 = 27%. The closest answer is 32% (
C), possibly due to rounding or partial overlap.
