. A nurse is preparing to administer 0.9% sodium chloride 1 L IV to infuse over 8 hr. The drop factor of the manual IV tubing set is 15 gtts/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 ["31"]
Desired volume: 1 L = 1,000 mL
Infusion time: 8 hours = 480 minutes
Drop factor: 15 gtts/mL
Formula: (Volume (mL) ÷ Time (min)) × Drop factor (gtts/mL)
= (1000 ÷ 480) × 15
= 31.25
Rounded to the nearest whole number: 31 gtt/min

Correct Answer is C
Explanation
A. Bounding: A bounding pulse indicates strong and forceful heartbeats, which is not typically associated with atrial fibrillation.
B. Slow: Atrial fibrillation is usually associated with an irregular and often rapid heart rate, not a slow heart rate.
C. Irregular: Atrial fibrillation is characterized by an irregularly irregular pulse due to the uncoordinated electrical activity in the atria, leading to an inconsistent pulse rate.
D. Not palpable: A pulse would not be expected to be "not palpable" in atrial fibrillation unless there is a severe circulatory issue, which is not the typical presentation.
Correct Answer is ["7.5"]
Explanation
Desired dose: 20 mEq
Available concentration: 40 mEq/15 mL
Formula:
mLtoadminister = (Desireddose÷ Availableconcentration) × 15mL
= (20mEq ÷ 40mEq) × 15
= 7.5mL
Therefore, the nurse should administer 7.5 mL of potassium chloride.
