Explanation
Determine the Desired Dose:
The healthcare provider prescribed 750 mg of metformin.
Determine the Available Dose:
Each tablet contains 500 mg of metformin.
Calculate the Number of Tablets:
Number of Tablets = Desired Dose / Available Dose
Number of Tablets = 750 mg / 500 mg
Number of Tablets = 1.5
Correct Answer is ["7.5"]
Explanation
Identify the Desired Dose:
The client needs 6 units of insulin per hour.
Identify the Available Concentration:
The solution has 200 units of insulin in 250 mL of NSS.
Set up the Proportion:
(Desired Dose / Available Concentration) = (Rate (mL/hr) / Volume (mL))
(6 units / 200 units) = (X mL / 250 mL)
Solve for X (the Rate):
Cross-multiply: 6 units x 250 mL = 200 units x X mL
1500 = 200X
X = 1500 / 200
X = 7.5 mL/hr
