- A patient with type 1 diabetes is prescribed a sliding scale insulin regimen using regular insulin before meals. The sliding scale is as follows:
Blood glucose 150-199 mg/dL: 2 units
Blood glucose 200-249 mg/dL: 4 units
Blood glucose 250-299 mg/dL: 6 units
Blood glucose 300-349 mg/dL: 8 units
Blood glucose >350 mg/dL: Call provider
The patient's blood glucose before lunch is 278 mg/dL. The patient is also prescribed 0.1 units/kg of insulin glargine (Lantus) once daily. The patient weighs 70 kg.
How many total units of insulin should the nurse administer at this time? (LABEL CORRECTLY: NO SPACES IN ANSWER)
The Correct Answer is ["13"]
Calculation:
- Determine the regular insulin dose based on the sliding scale.
The patient's blood glucose before lunch is 278 mg/dL.
According to the sliding scale:
Blood glucose 250-299 mg/dL: 6 units
Therefore, the regular insulin dose is 6 units.
- Calculate the insulin glargine (Lantus) dose.
Client weight = 70 kg.
Prescription for insulin glargine = 0.1 units/kg once daily.
Insulin glargine dose = 0.1 units/kg × 70 kg = 7 units.
- Calculate the total units of insulin to administer.
Total units = Regular insulin units + Insulin glargine units
Total units = 6 units + 7 units
= 13 units.

Explanation
Calculation:
- Determine the regular insulin dose based on the sliding scale.
The patient's blood glucose before lunch is 278 mg/dL.
According to the sliding scale:
Blood glucose 250-299 mg/dL: 6 units
Therefore, the regular insulin dose is 6 units.
- Calculate the insulin glargine (Lantus) dose.
Client weight = 70 kg.
Prescription for insulin glargine = 0.1 units/kg once daily.
Insulin glargine dose = 0.1 units/kg × 70 kg = 7 units.
- Calculate the total units of insulin to administer.
Total units = Regular insulin units + Insulin glargine units
Total units = 6 units + 7 units
= 13 units.
Correct Answer is D
Explanation
A. Pulse oximeter reading 96%: A pulse oximeter reading of 96% is within the normal range (95-100%) and does not warrant immediate intervention. This indicates that the client's oxygen saturation is adequate.
B. Serum blood glucose level of 74 mg/dL: A serum blood glucose level of 74 mg/dL is within the normal range (70-100 mg/dL) for a fasting blood glucose level. This does not indicate an urgent issue, and no immediate intervention is needed for this value.
C. The client is lethargic and sleeps all the time: Lethargy and excessive sleep can be symptoms of myxedema coma, as it is a severe form of hypothyroidism. However, this is a common manifestation of the condition and does not require immediate intervention
D. Telemetry reading showing sinus bradycardia: Sinus bradycardiais common in myxedema coma due to the decreased metabolic rate associated with severe hypothyroidism. However, if the heart rate becomes too low, it can lead to serious complications like cardiac arrest.
