A nurse is preparing to administer Ringer lactate 500 mL intravenous (IV) bolus to infuse over 3 hours. The drop factor of the manual IV tubing is 2 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 ["56"]

To calculate the infusion rate, we'll use the following formula:

Infusion rate (gtt/min) = (Volume to be infused (mL) / Time (min))  Drop factor (gtt/mL)

First, calculate the total time in minutes:

  • 3 hours  60 minutes/hour = 180 minutes

Then, calculate the volume per minute:

  • 500 mL / 180 minutes = 2.78 mL/min

Finally, multiply the volume per minute by the drop factor:

  • 2.78 mL/min  20 gtt/mL = 55.6 gtt/min

Therefore, the nurse should set the manual IV infusion to deliver 56 gtt/min.

Correct Answer is B

Explanation

A. Manually irrigate the catheter: This action is premature if the issue is due to a kink or obstruction in the tubing. Manual irrigation should only be performed if other less invasive measures do not resolve the issue.
B. Check the catheter tubing for kinks: This is the first step to take as kinks in the tubing can obstruct the flow of urine. Identifying and correcting kinks may resolve the problem without further intervention.
C. Notify the healthcare provider: This step may be necessary if other interventions do not resolve the issue, but it is not the first action.
D. Adjust the rate of the bladder irrigant: This may be relevant if the problem is related to the irrigation rate, but checking for kinks should be done first to ensure proper catheter function.

Correct Answer is A

Explanation

A. "I can detect the presence of carbon monoxide by a metallic odor." This is incorrect. Carbon monoxide is odorless, colorless, and tasteless, making it undetectable by smell.
B. "A high concentration of carbon monoxide can cause unconsciousness." This is correct. High levels of carbon monoxide can lead to serious symptoms including loss of consciousness.
C. "Breathing in carbon monoxide can cause headaches and nausea." This is correct. Symptoms of carbon monoxide poisoning include headaches, nausea, and dizziness.
D. "Leaky gas or oil furnaces can cause carbon monoxide poisoning." This is correct. Faulty or leaky heating systems can be a source of carbon monoxide exposure.
