A nurse is caring for a patient who is diagnosed with diabetes and a new prescription for 14 units of regular insulin and 28 units of NPH insulin subcutaneously at breakfast daily. What is the total number of units of insulin that the nurse should prepare in the insulin syringe? (round to the nearest whole number)
28 units
42 units
14 units
32 units
The Correct Answer is B
A. 28 units only accounts for the NPH insulin dosage and does not include the regular insulin dosage.
B. Adding 14 units of regular insulin and 28 units of NPH insulin results in a total of 42 units, the correct dose to prepare in the syringe.
C. 14 units only accounts for the regular insulin dosage and does not include the NPH insulin dosage.
D. 32 units is not the correct total dose; it underestimates the combined dosage.

Correct Answer is A
Explanation
A. Elevating the head of the bed, loosening clothing, and checking for urinary catheter obstruction are key steps to lower blood pressure and relieve triggers of autonomic dysreflexia, a potentially life-threatening condition.
B. A cool compress may provide comfort but does not directly address the primary triggers or symptoms of autonomic dysreflexia.
C. Semi-Fowler's position is insufficient compared to a full 90-degree sitting position, which helps reduce blood pressure.
D. IV access and oxygen may be required if symptoms do not resolve, but immediate actions focus on relieving the cause of dysreflexia.
Correct Answer is A
Explanation
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.
