pH 7.35, PaO2 75 mmHg, PaCO2 48 mmHg, HCO3 27 mEq/L

pH 7.30, PaO2 90 mmHg, PaCO2 44 mmHg, HCO3 18 mEq/L

Answer and Explanation

The Correct Answer is A

A. A pH within the normal range, a PaCO2 within the normal range, and an improved PaO2 level suggest effective treatment for an asthma attack, indicating adequate gas exchange and resolution of respiratory distress.

B. A pH of 7.52 and low PaCO2 suggest respiratory alkalosis, which can occur with hyperventilation and may indicate overventilation rather than effective asthma treatment.

C. This result shows elevated PaCO2 and borderline low PaO2, indicating ongoing respiratory acidosis and hypoxia, suggesting the treatment is not yet effective.

D. This ABG result shows low pH, indicating acidosis, and a low bicarbonate level, which may indicate metabolic acidosis rather than effective asthma management.

Correct Answer is ["0.5"]

Explanation

To administer the correct dose of Morphine, the nurse needs to calculate the volume of medication to deliver 1 mg of Morphine. Since the medication is supplied in a concentration of 2 mg per 1 mL, the nurse would administer half of the volume of the vial to provide the ordered 1 mg dose. Therefore, the nurse should administer 0.5 mL of Morphine to the patient.

A. Clarify misinformation and reorient when confused B. Turn patient every 2 hours C. Ensure bed alarm is on when leaving the patient's room D. Vary schedule to prevent memorization and boredom

Correct Answer is C

Explanation

A. Reorienting confused patients is important but is not directly related to cerebellar injury.

B. While turning every 2 hours is important to prevent pressure injuries, it does not address the specific fall risk associated with cerebellar damage.

C. The cerebellum is responsible for balance and coordination, so injuries in this area increase the risk of falls. Ensuring the bed alarm is on provides immediate alerts if the patient attempts to get out of bed, helping to prevent falls.

D. Varying the schedule to prevent boredom is not a priority in the care of patients with cerebellar injury.
