A nurse is preparing to administer lactated Ringer's 400 mL IV bolus to infuse over 3 hr. The drop factor of the manual IV tubing is 20 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.)

Answer and Explanation

The Correct Answer is ["44"]

Calculate the flow rate in mL/hour: 400 mL / 3 hours = 133.33 mL/hour (approximately)

Convert the flow rate to mL/minute: 133.33 mL/hour / 60 minutes/hour = 2.22 mL/minute (approximately)

Calculate the drops per minute: 2.22 mL/minute 20 gtt/mL = 44.4 gtt/minute

Round to the nearest whole number: 44 gtt/minute

Correct Answer is B

Explanation

A. Flushed skin is typically associated with fever or infection, not with hyponatremia (low sodium levels).
B. Confusion is a common symptom of hyponatremia, especially when sodium levels drop significantly. The low sodium level affects brain function, leading to confusion, altered mental status, and even seizures in severe cases.
C. Extreme thirst is more commonly seen in hypernatremia (high sodium levels) as the body attempts to correct the imbalance by stimulating thirst.
D. Fever is not a direct consequence of hyponatremia but could be associated with an underlying infection or other conditions.

A. Lispro lasts 24 hours and does not have to be timed with meals. B. 60 minutes before meals. C. 15-30 minutes before meals. D. 2-6 hours before meals.

Correct Answer is C

Explanation

A. This statement is incorrect. Lispro is a rapid-acting insulin, and its duration of action is much shorter than 24 hours. It is typically effective for about 3-5 hours.
B. Administering Lispro 60 minutes before meals would be too early, as it peaks in about 1-2 hours after injection and works best when given closer to meal times.
C. Lispro should be administered 15-30 minutes before meals to match the onset of action, which begins within 15 minutes of injection. This timing allows the insulin to be active when blood glucose rises after eating.
D. Lispro does not require administration 2-6 hours before meals, as this would not align with its rapid onset of action.
