The doctor orders 250 mg of an antibiotic. The stock supply is a vial of 250 mg of the drug. Directions say to reconstitute with 1.7 mL of sterile water to yield 2 mL of the drug. How many milliliters will you give for the correct dose?

Given:

Volume of fluid: 50 mL (DSW)

Infusion time: 30 minutes

Drop factor: 10 gtt/mL

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (min)) x Drop factor (gtt/mL)

Step 1: Calculate the infusion rate in mL/min:

Infusion rate (mL/min) = Volume (mL) / Time (min)

Infusion rate (mL/min) = 50 mL / 30 min

Infusion rate (mL/min) = 1.67 mL/min

Step 2: Calculate the flow rate in gtt/min:

Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)

Flow rate (gtt/min) = 1.67 mL/min x 10 gtt/mL

Flow rate (gtt/min) = 16.7 gtt/min

Step 3: Round to the nearest whole number:

Flow rate (gtt/min) ≈ 17 gtt/min

A) High protein diet:
A high-protein diet is generally not a recommended nonpharmacological treatment for heart failure. While adequate protein intake is important for overall health, heart failure management typically focuses more on regulating sodium, fluid, and caloric intake. In some cases, a high-protein diet could place additional strain on the kidneys or exacerbate other conditions that may complicate heart failure.

B) Limit salt intake:
Limiting salt (sodium) intake is a crucial nonpharmacological strategy in managing heart failure. Excessive sodium can cause the body to retain water, leading to fluid overload, which can worsen heart failure symptoms such as edema, shortness of breath, and elevated blood pressure. Reducing sodium intake helps prevent these complications and aids in controlling symptoms.

C) 50 pound weight loss:
While weight loss may be beneficial for some individuals, especially those who are obese, a sudden or extreme weight loss of 50 pounds is not typically advised for someone with heart failure unless supervised by a healthcare provider. Rapid weight loss can lead to dehydration or electrolyte imbalances, which may exacerbate heart failure symptoms.

D) Decrease Water intake:
While fluid restriction may be necessary for some individuals, especially those with severe fluid retention or in advanced stages of heart failure, it is not a blanket recommendation. The approach to fluid intake should be based on the individual’s condition, including factors such as kidney function and the presence of edema.
