A client with type 1 diabetes mellitus (DM) is admitted in diabetic ketoacidosis. Treatment is initiated, and the nurse is preparing to administer IV fluids containing potassium chloride. Which assessment data is most important for the nurse to obtain before starting the infusion?
Urinary output of 30 to 60 mL/hr.
Magnesium level.
Size of the IV catheter.
Serum glucose level.
The Correct Answer is A
Choice A reason: Before administering IV fluids containing potassium chloride, it is crucial to ensure that the client has adequate urinary output, typically between 30 to 60 mL/hr. This indicates good kidney function, which is necessary for the excretion of potassium to prevent hyperkalemia, a potentially life-threatening condition.
Choice B reason: While magnesium levels can affect potassium levels, they are not the most critical assessment before potassium infusion. However, it is important to monitor magnesium levels as part of the overall electrolyte balance, especially in diabetic ketoacidosis.
Choice C reason: The size of the IV catheter is important for administration purposes, but it is not the most critical assessment data before starting potassium infusion. The catheter size affects the flow rate and comfort during infusion but does not impact the decision to start the infusion.
Choice D reason: Serum glucose level is a vital parameter to monitor in diabetic ketoacidosis, but it is not the most critical assessment before starting potassium infusion. The primary concern with potassium infusion is kidney function, as assessed by urinary output.

Correct Answer is ["2.4"]
Explanation
Step 1: Convert the weight from pounds to kilograms. We know that 1 kg = 2.2 lbs. So, the weight in kg is:
175 lbs ÷ 2.2 = 79.55 kg
Step 2: Calculate the total units of heparin needed. The prescription is for 3 units/kg, so:
3 units/kg × 79.55 kg = 238.65 units
Step 3: Calculate the volume of heparin to administer. The vial is labeled as "100 units/mL", so:
238.65 units ÷ 100 units/mL = 2.39 mL
So, the nurse should administer approximately 2.4 mL of heparin (rounded to the nearest tenth).
Correct Answer is {"A":{"answers":"A"},"B":{"answers":"A"},"C":{"answers":"B"},"D":{"answers":"C"},"E":{"answers":"C"}}
Explanation
Choice A Reason: A BMI of 28 kg/m² is considered overweight and is a modifiable risk factor for type 2 diabetes mellitus. Weight loss through diet and exercise can reduce the risk.
Choice B Reason: An HDL level of 43 mg/dL (1.11 mmol/L) is slightly below the recommended range and is a modifiable risk factor. Increasing HDL can be achieved through lifestyle changes such as exercise and dietary adjustments.
Choice C Reason: Having a sister with type 2 diabetes mellitus is a non-modifiable risk factor as it is related to genetic predisposition.
Choice D Reason: Occupational fume exposure is generally considered unrelated to the development of type 2 diabetes mellitus.
Choice E Reason: Cannabis use is typically unrelated to type 2 diabetes mellitus, though research on its long-term metabolic effects is ongoing.
Normal Ranges:
- BMI: 18.5 to 24.9 kg/m² (normal)
- HDL (High-Density Lipoprotein): Greater than 45 mg/dL (Greater than 1.15 mmol/L)
- LDL (Low-Density Lipoprotein): Less than 130 mg/dL (Less than 3.4 mmol/L)
- Fasting Blood Glucose: 74 to 106 mg/dL (4.1 to 5.9 mmol/L)
