. 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.)

Answer and Explanation

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.

A. "Be sure to wear this equipment for the next 24 hours. B. You might feel some slight tingling during the procedure." C. Try to remain still once I have attached the gel pads. D. "I will be placing some electrodes on your scalp."

Correct Answer is C

Explanation

A. "Be sure to wear this equipment for the next 24 hours." This statement applies to a Holter monitor, not a 12-lead ECG. A 12-lead ECG is a brief, one-time test.

B. "You might feel some slight tingling during the procedure." A 12-lead ECG does not involve any sensation like tingling. It simply records the heart’s electrical activity without causing any discomfort.

C. "Try to remain still once I have attached the gel pads." Movement during an ECG can interfere with the results by causing artifact, so it's important for the client to remain still while the test is being performed.

D. "I will be placing some electrodes on your scalp."Electrodes for a 12-lead ECG are placed on the chest and limbs, not on the scalp.
