A client is admitted with diabetic ketoacidosis (DKA) and is receiving an IV infusion of 0.9% sodium chloride and insulin. Two hours later, the client's serum laboratory results show a decrease in the serum blood glucose from 580 to 430 mg/dL (32.2 to 23.86 mmol/L). It is most
important for the nurse to monitor which additional laboratory result?
Reference Range

Serum potassium.

Urine ketones.

Serum sodium.

Blood urea nitrogen (BUN).

Answer and Explanation

The Correct Answer is A

A.   Serum potassium. Insulin therapy causes potassium to move into cells, which can lead to hypokalemia. Monitoring serum potassium is critical because significant drops can lead to cardiac arrhythmias and other complications.
B.   Urine ketones. While monitoring ketones is important for assessing the resolution of DKA, it is not as immediately critical as monitoring potassium levels.
C.   Serum sodium. Sodium levels are important but typically do not change as rapidly as potassium levels during DKA treatment.
D.   Blood urea nitrogen (BUN). BUN levels provide information about kidney function and hydration status but are less immediately critical than potassium levels in the context of insulin therapy for DKA.

Correct Answer is C

Explanation

Activity restriction does not directly decrease abdominal pain. Pain management in Crohn’s disease is typically achieved through medications, dietary adjustments, and addressing inflammation.

B. While activity restriction may indirectly help decrease abdominal pain by reducing inflammation and promoting healing, it is not the primary purpose of the restriction.
C.The primary goal of activity restriction in Crohn's disease is to reduce intestinal activity. By limiting physical exertion, the intestines are less stimulated, which can help reduce inflammation and give the digestive system a chance to rest and recover.
D. While activity restriction may help control diarrhea episodes by reducing physical stress on the intestines, the primary purpose is to promote healing and reduce inflammation. Control of diarrhea may be achieved through other interventions such as dietary modifications and
medication management.

A. Oxygen is less toxic when it is humidified with a hydration source. B. Avoid administration of oxygen at high levels for extended periods. C. Increase oxygen rate during sleep to compensate for slower respiratory rate. D. Taking a sedative at bedtime slows respiratory rate, which decreases oxygen needs.

Correct Answer is B

Explanation

A. Oxygen is less toxic when it is humidified with a hydration source. While humidification can prevent drying of the respiratory mucosa, it does not directly relate to the principle of avoiding high levels of oxygen for extended periods.
B. Avoid administration of oxygen at high levels for extended periods. This is the correct principle. Prolonged exposure to high levels of oxygen can lead to oxygen toxicity, which can cause lung damage. Oxygen therapy should be titrated to maintain adequate oxygenation without exposing the patient to excessive oxygen levels.
C. Increase oxygen rate during sleep to compensate for slower respiratory rate. This statement is incorrect. Oxygen therapy should be adjusted based on the patient's oxygen saturation levels and respiratory status, not solely on sleep patterns.
D. Taking a sedative at bedtime slows respiratory rate, which decreases oxygen needs. While sedatives can depress respiratory rate, leading to decreased oxygen needs, this is not a general principle of oxygen administration. Oxygen therapy should be based on the patient's oxygenation needs rather than medications they are taking.
