As a result of opioid administration, a child's respirations are slow and shallow. Which should the nurse anticipate when assessing the child's arterial blood gas?
- A. Increased PCO2 and respiratory acidosis
- B. Decreased PCO2 and respiratory alkalosis
- C. Low pH and low PCO2
- D. High pH and high PCO2
Correct Answer: A
Rationale: When a child's respirations are slow and shallow due to opioid administration, it results in hypoventilation. This leads to retaining carbon dioxide, indicated by an increased PCO2 level on arterial blood gas analysis, and subsequently causes respiratory acidosis due to the buildup of CO2 in the blood.
A 9-month-old infant who is not sitting independently has been diagnosed with ataxic cerebral palsy (CP). Which clinical manifestations would the nurse expect to see in the baby?
- A. Hypotonia and muscle instability
- B. Hypertonia and persistence of primitive reflexes
- C. Tremors and exaggerated posturing
- D. Hemiplegia and hypertonia
Correct Answer: A
Rationale: In ataxic cerebral palsy, the characteristic features include hypotonia (low muscle tone) and muscle instability. These manifestations contribute to the infant's difficulty in achieving independent sitting. Hypertonia (increased muscle tone) and persistence of primitive reflexes, as mentioned in option B, are more commonly associated with other types of cerebral palsy. Tremors and exaggerated posturing (option C) are not typical features of ataxic CP. Hemiplegia (paralysis of one side of the body) and hypertonia (increased muscle tone) mentioned in option D are more commonly seen in other types of cerebral palsy, such as spastic CP.

- D. A serum glucose of 110 mg/dL.
