ATI NCLEX-RN Practice Questions Questions
Extract:
Question 1 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 2 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.

The nurse is preparing to administer a dose of morphine sulfate IV to a client for pain. Which assessment is most important before administration?
Correct Answer: A
Rationale: Morphine, an opioid, can cause respiratory depression. Assessing the respiratory rate is critical before administration to ensure it is above 12 breaths per minute, preventing overdose risk. Other vital signs are monitored but are less critical.
Question 4 of 5

Correct Answer: C
Rationale: Progesterone from the corpus luteum causes endometrial swelling in the secretory phase, preparing for potential implantation.
