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 C

Explanation

A. Initiate intravenous (IV) access for fluid replacement. This is important for managing shock or significant blood loss, but it is not the first priority in managing severe bleeding.
B. Place the client's arm in a dependent position. This would not be appropriate for severe bleeding and does not control hemorrhage effectively.
C. Apply pressure directly to the wound. This is correct. Direct pressure is the immediate and essential step to control bleeding in a severe wound. It helps to stabilize the clot and reduce blood loss.
D. Apply a tourniquet just below the level of the shoulder. This is not the first intervention. A tourniquet is used if direct pressure does not control severe bleeding and should be applied above the wound, not below.

A. Flu-like symptoms B. Vesicles on the skin C. Respiratory failure D. Flaccid paralysis

Correct Answer is A

Explanation

A. Flu-like symptoms: This is correct. Inhalation anthrax initially presents with flu-like symptoms, including fever, cough, and malaise. This early presentation can progress to severe respiratory distress and systemic illness.
B. Vesicles on the skin: This is incorrect. Vesicular lesions are more characteristic of diseases such as smallpox or chickenpox, not anthrax.
C. Respiratory failure: While respiratory failure can occur with advanced inhalation anthrax, it is a later-stage complication rather than an initial finding.
D. Flaccid paralysis: This is incorrect. Flaccid paralysis is not a typical symptom of anthrax exposure but may be associated with diseases such as botulism.
