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. Prepare the client for transfer to a facility with a hyperbaric chamber: This may be required for severe cases of carbon monoxide poisoning, but immediate intervention with high-flow oxygen is essential first.
B. Apply oxygen via a nonrebreather mask at 15 liters: Carbon monoxide poisoning requires immediate high-flow oxygen to help displace carbon monoxide from hemoglobin. This is the first step in treatment to prevent further tissue hypoxia and complications.
C. Check the client's oxygenation level with a pulse oximeter: While important, it does not address the immediate need for high-flow oxygen to treat carbon monoxide poisoning.
D. Administer intravenous (IV) fluids: IV fluids may be necessary for supportive care but are not the priority for treating carbon monoxide poisoning. The immediate need is to provide high-flow oxygen.

A. Hormone therapy decreases the risk of cardiovascular events. B. Hormone therapy may prevent osteoporotic fractures. C. Hormone therapy should be taken in doses throughout the day. D. If a dose is missed, then the next dose should be doubled.

Correct Answer is B

Explanation

A. Hormone therapy decreases the risk of cardiovascular events: This is incorrect. Hormone therapy can actually increase the risk of cardiovascular events, including heart disease and stroke.
B. Hormone therapy may prevent osteoporotic fractures: This is correct. Hormone therapy can help maintain bone density and reduce the risk of osteoporotic fractures in women undergoing menopause.
C. Hormone therapy should be taken in doses throughout the day: This is incorrect. Hormone therapy is usually taken in a single daily dose or as directed by a healthcare provider, not throughout the day.
D. If a dose is missed, then the next dose should be doubled: This is incorrect. Missing a dose of hormone therapy should be managed according to the provider's instructions, which typically do not involve doubling the next dose.
