The patient is ordered Glucerna 1.2 calories. You're supplied with a can of Glucerna that contains 237 mL. The doctor orders the tube feeding to be administered at a 1/2 strength with a rate of 65 mL/hr. How much water will you add to dilute the tube feeding formula as prescribed?
237 mL
68 mL
474 mL
118.5 ml
The Correct Answer is D
Given:
Volume of Glucerna 1.2: 237 mL
Desired concentration: 1/2 strength
Step 1: Determine the volume of Glucerna 1.2 needed for the half-strength solution:
Volume of Glucerna 1.2 for half-strength = Original volume / 2
Volume of Glucerna 1.2 for half-strength = 237 mL / 2
Volume of Glucerna 1.2 for half-strength = 118.5 mL
Step 2: Calculate the amount of water to be added:
Amount of water = Original volume - Volume of Glucerna 1.2 for half-strength
Amount of water = 237 mL - 118.5 mL
Amount of water = 118.5 mL

Correct Answer is C
Explanation
A) High protein diet:
While a healthy diet is essential for managing heart disease, a high-protein diet is not specifically recommended as a nonpharmacologic control for heart disease. A balanced diet that includes adequate protein, healthy fats, and low saturated fats, while being high in fruits, vegetables, and whole grains, is more beneficial for heart health.
B) Decrease exercise:
Decreasing exercise is not recommended for heart disease management. In fact, regular physical activity is a key aspect of preventing and managing heart disease. Moderate exercise, such as walking, swimming, or cycling, helps improve cardiovascular health by lowering blood pressure, improving cholesterol levels, and reducing stress.
C) Smoking cessation:
Smoking cessation is one of the most important nonpharmacologic strategies for managing heart disease. Smoking is a major risk factor for heart disease because it damages the blood vessels, increases blood pressure, and promotes the formation of blood clots. Quitting smoking can significantly reduce the risk of heart disease, improve circulation, and lower the risk of heart attack and stroke.
D) Increase water intake:
While staying hydrated is important for overall health, there is no specific evidence to suggest that increasing water intake directly controls heart disease. However, maintaining proper hydration supports kidney function and circulatory health, and can assist with managing blood pressure.
Correct Answer is B
Explanation
Given:
Volume of fluid: 500 mL
Infusion time: 8 hours
Drop factor: 10 gtt/mL
Medication volume: 10 mL (added to the fluid)
Step 1: Calculate the total volume to be infused:
Total volume = Volume of fluid + Volume of medication
Total volume = 500 mL + 10 mL
Total volume = 510 mL
Step 2: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
Infusion rate (mL/hr) = 510 mL / 8 hr
Infusion rate (mL/hr) = 63.75 mL/hr
Step 3: Calculate the infusion rate in gtt/min:
Infusion rate (gtt/min) = Infusion rate (mL/hr) x Drop factor (gtt/mL) / 60 min/hr
Infusion rate (gtt/min) = 63.75 mL/hr x 10 gtt/mL / 60 min/hr
Infusion rate (gtt/min) = 10.625 gtt/min
Step 4: Round to the nearest whole number:
Infusion rate (gtt/min) ≈ 11 gtt/min
