Calculate the flow rate in mL/hr. (Equpment used is programmable in whole mL/hr) 180 mL 0.45% NS in 40 min by infusion group

Given:

Ordered dose of Heparin: 9 units/kg/hr

Patient weight: 76 kg

Concentration of Heparin: 50 units/mL

Step 1: Calculate the total dose of Heparin:

Total dose (units/hr) = Ordered dose (units/kg/hr) x Patient weight (kg)

Total dose (units/hr) = 9 units/kg/hr x 76 kg

Total dose (units/hr) = 684 units/hr

Step 2: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Total dose (units/hr) / Concentration (units/mL)

Infusion rate (mL/hr) = 684 units/hr / 50 units/mL

Infusion rate (mL/hr) = 13.68 mL/hr

Step 3: Round to the nearest tenth:

Infusion rate (mL/hr) ≈ 13.7 mL/hr

A) 6 Units Regular Insulin sub-cut:
According to the sliding scale, a blood glucose level of 164 mg/dL would not fall within the range requiring 6 units of insulin. The 6-unit dose is for blood glucose levels between 301-490 mg/dL. Since the client's reading of 164 mg/dL is lower than 181 mg/dL, this dosage is not applicable.

B) 2 Units Regular Insulin sub-cut:
This is also incorrect. The 2-unit dose is prescribed for blood glucose levels between 181-240 mg/dL. Since the client's reading is 164 mg/dL, it falls below this range, so 2 units is not appropriate.

C) 0.5 Units Regular insulin sub-cut:
This is not correct because there is no provision in the sliding scale for administering 0.5 units of insulin. The scale provides dosing for specific ranges and does not include fractional doses. Additionally, the blood glucose reading of 164 mg/dL does not require any insulin according to the prescribed sliding scale.

D) No coverage:
According to the sliding scale, a blood glucose level of 164 mg/dL falls within the 0-180 mg/dL range, which specifies no coverage or insulin administration. The sliding scale clearly indicates that no insulin is needed when the blood glucose level is within this range.
