Between 2-6 months of life, all are true about infant sleep EXCEPT

Correct Answer: A

Rationale: Oxygen saturation above 90% is a discharge criterion from the PACU (Post-Anesthesia Care Unit) for a patient following surgery. This indicates that the patient is effectively exchanging oxygen and carbon dioxide, which is essential for proper respiratory function. Adequate oxygenation is crucial for the patient to be safely discharged from the PACU and transitioned to a regular hospital room or home. Monitoring oxygen saturation helps ensure that the patient's respiratory status is stable before leaving the PACU. If a patient's oxygen saturation is below 90%, further assessment and interventions may be necessary before discharge is considered.

Correct Answer: C

Rationale: HUS typically presents with mild proteinuria along with increased BUN and creatinine, reflecting impaired renal function.

Correct Answer: D

Rationale: The correct client statement indicating effective teaching about parenteral vitamin B12 therapy for pernicious anemia is, "I will receive parenteral vitamin B12 therapy for the rest of my life." Pernicious anemia is a condition in which the body cannot absorb enough vitamin B12 from food due to a lack of intrinsic factor, a protein produced in the stomach. As a result, lifelong B12 supplementation is necessary to maintain adequate levels of the vitamin. Monthly injections are typically recommended for life to ensure proper B12 levels and prevent complications associated with the deficiency.

Correct Answer: E

Rationale: Differentiating agents like 13-cis-retinoic acid are used instead of allogenic bone marrow transplantation in high-risk neuroblastoma.
