A nurse is preparing to administer potassium chloride 40 mEq in dextrose 5% in 0.9% sodium chloride 1,000 mL IV to infuse over 8 hr. The tubing has a drop factor of 15 gtt/mL.
The nurse should set the IV flow rate 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 ["31"]
To calculate the IV flow rate in drops per minute (gtt/min), we can use the following steps:
Calculate the total number of minutes for the infusion:
8 hours × 60 minutes/hour = 480 minutes
Determine the total number of drops needed for the infusion:
The total volume to be infused is 1000 mL.
The drop factor is 15 gtt/mL.
1000 mL × 15 gtt/mL = 15000 gtt
Calculate the IV flow rate in drops per minute:
15000 gtt ÷ 480 min ≈ 31 gtt/min
Rounding to the nearest whole number, the nurse should set the IV flow rate to deliver 31 gtt/min.

Correct Answer is D
Explanation
Choice A reason: This choice is incorrect because fluids should not be limited to 1000 mL daily for a client taking hydrochlorothiazide. Hydrochlorothiazide is a diuretic that causes the body to lose water and salt through urine. Limiting fluids can lead to dehydration, electrolyte imbalance, and kidney damage. The client should drink enough fluids to prevent thirst and dry mouth, and follow the doctor's advice on fluid intake.
Choice B reason: This choice is incorrect because this medication is not best taken at night for a client taking hydrochlorothiazide. Hydrochlorothiazide can cause frequent urination, which can disrupt the sleep cycle and cause fatigue. The client should take this medication in the morning or at least 4 hours before bedtime to avoid nocturia (nighttime urination).
Choice C reason: This choice is incorrect because dairy products should not be avoided while on this medication for a client taking hydrochlorothiazide. Hydrochlorothiazide can lower the level of calcium in the blood, which can cause muscle weakness, cramps, and osteoporosis. Dairy products are a good source of calcium and can help prevent calcium deficiency. The client should consume adequate amounts of calcium and vitamin D, and have their blood calcium level checked regularly.
Choice D reason: This choice is correct because the client should consume high potassium foods such as bananas and oranges while on this medication. Hydrochlorothiazide can lower the level of potassium in the blood, which can cause irregular heartbeat, muscle weakness, and numbness. Potassium-rich foods can help prevent potassium deficiency and maintain normal heart and muscle function. The client should also have their blood potassium level checked regularly and avoid salt substitutes that contain potassium.
Correct Answer is ["8"]
Explanation
To calculate the amount of phenytoin oral suspension to administer, we can use the following formula:
Amount to administer (mL) = (Desired dose (mg) / Available dose (mg/mL))
Plugging in the given values:
Amount to administer (mL) = (200 mg / 125 mg/5 mL)
Now, let's solve for the amount to administer:
Amount to administer (mL) = (200 mg / 125 mg/5 mL) = (200 / 125) 5 = 8
So, the nurse should administer 8 mL of phenytoin oral suspension via the gastrostomy tube.
