A nurse is preparing to administer dextrose 5% in water 350 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["19"]
Drip rate (gtt/min) = (Volume to be infused in mL × Drop factor) ÷ Time of infusion in minutes
Given:
Volume to be infused = 350 mL Drop factor = 10 gtt/mL
Time of infusion = 3 hours = 180 minutes
Plugging these values into the formula:
Drip rate = (350 mL × 10 gtt/mL) ÷ 180 min Drip rate ≈ (3500 gtt) ÷ 180 min
Drip rate ≈ 19.4 gtt/min
Rounding to the nearest whole number, the drip rate is approximately 19 gtt/min. Therefore, the nurse should set the manual IV infusion to deliver 19 gtt/min.

Correct Answer is C
Explanation
A. Hang the TPN solution to gravity to infuse: TPN solutions are typically administered using an infusion pump to control the rate of infusion accurately. Hanging the solution to gravity is not recommended because it may lead to inconsistent flow rates and inaccurate delivery of nutrients.
B. Titrate TPN solution to blood pressure: TPN solutions are not titrated based on blood pressure.
The composition and rate of TPN infusion are typically determined by the client's nutritional needs and metabolic status, not blood pressure.
C. Monitor the client's weight daily: Monitoring the client's weight daily is essential when administering TPN to assess for fluid balance, nutritional status, and response to therapy. Changes in weight can indicate fluid retention, dehydration, or changes in nutritional status, which may require adjustments to the TPN regimen.
D. Obtain the client's blood glucose level weekly: Blood glucose levels should be monitored frequently in clients receiving TPN, as hyperglycemia is a common complication. Weekly monitoring may not be sufficient to detect and manage hyperglycemia promptly. Therefore,
blood glucose levels are typically monitored more frequently, such as multiple times daily or according to institutional protocols.
Correct Answer is C
Explanation
A. Hypomagnesemia: While lithium can affect magnesium levels, starting a new exercise program is not typically associated with hypomagnesemia. Hypomagnesemia may result in muscle weakness, tremors, and cardiac dysrhythmias.
B. Hypocalcemia: Starting a new exercise program is not typically associated with hypocalcemia. Hypocalcemia may present with muscle cramps, tetany, and seizures.
C. Hyponatremia: Starting a new exercise program may lead to dehydration and electrolyte imbalances, including hyponatremia (low sodium levels). This can have profound effects on patients taking lithium. Symptoms of hyponatremia include weakness, confusion, and seizures.
D. Hypokalemia is not a common occurrence among individuals doing exercise.
