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
A male client was involved in a motor vehicle accident earlier in the day. The nurse caring for him on evenings notices that on admission to the hospital, he lost a lot of blood and required multiple blood transfusions. The nurse would anticipate which blood product would be ordered when a large blood loss has occurred?
Correct Answer: A
Rationale: Whole blood is the transfusion component of choice when large volumes of blood need to be replaced. Whole blood contains all blood components that are lost during active bleeding.
Question 3 of 5
The nurse is caring for a client with a history of Parkinson’s disease. The nurse should give priority to:
Correct Answer: A
Rationale: Parkinson’s disease causes bradykinesia and rigidity, increasing fall risk, so monitoring for falls is the priority.
Question 4 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 5 of 5
Which of the following signs and symptoms indicates a tension pneumothorax as compared to an open pneumothorax?
Correct Answer: C
Rationale: The tension pneumothorax acts like a one-way valve so that the pneumothorax increases with each breath. Eventually, it occupies enough space to shift mediastinal tissue toward the unaffected side away from the midline. Tracheal deviation, movement of point of maximum impulse, and decreased cardiac output will occur. The other three options will occur in both types of pneumothorax.
