ATI NCLEX-RN Practice Questions Questions
Extract:
Question 1 of 5
Which ECG finding is most likely to be present in the client with a potassium of 6.0 mEq/L?
Correct Answer: C
Rationale: Hyperkalemia (potassium 6.0 mEq/L) typically causes peaked T waves on an ECG due to altered cardiac repolarization. Depressed S-T segments and U waves are more associated with hypokalemia and T/U wave fusion is less common.
Question 2 of 5
The nurse is assessing a six-year-old following a tonsillectomy. Which one of the following signs is an early indication of hemorrhage?
Correct Answer: A
Rationale: Drooling of bright red secretions indicates active bleeding post-tonsillectomy, an early sign of hemorrhage requiring immediate attention.
Question 3 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.
Question 4 of 5
A client is scheduled for a magnetic resonance imaging (MRI) to locate a cerebral lesion. It is important for the nurse to find out if he has a(n):
Correct Answer: C
Rationale: Iodine is not used as a contrast medium for MRI. It is important to inquire about allergy to seafood if the client is to have an arteriogram or enhanced computer tomography. MRI is safe if seizures are under control. It is more important to inquire about movable metal implants. Clients with movable metal implants such as shrapnel or aneurysm clips or clients with permanent pacemakers or implanted pumps can be traumatized during an MRI. Nonmovable metal prostheses or hardware will not cause trauma during an MRI.
Question 5 of 5
A client with a femoral popliteal bypass graft is assigned to a semiprivate room. The most suitable roommate for this client is the client with:
Correct Answer: A
Rationale: The client with hypothyroidism is the most suitable roommate, as this condition is non-infectious and poses no risk to the immunocompromised vascular surgery client. Gastroenteritis and bacterial pneumonia are infectious, and diabetic ulcers may involve infection, increasing cross-contamination risk.
