A nurse is preparing to administer cefazolin 1 g by intermittent intravenous (IV) bolus over 30 minutes. Available is cefazolin 1 g in 100 mL dextrose 5% in water (D5W). The drop factor of the manual IV tubing is 10 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. Only enter numbers and decimals. Do not enter any letters in your answer.)
The Correct Answer is ["33"]
To calculate the infusion rate, we'll use the following formula:
Infusion rate (gtt/min) = (Volume to be infused (mL) / Time (min)) ) x Drop factor (gtt/mL)
First, calculate the total volume to be infused:
- 100 mL / 30 min = 3.33 mL/min
Then, multiply the volume per minute by the drop factor:
- 3.33 mL/min x 10 gtt/mL = 33.3 gtt/min
Therefore, the nurse should set the manual IV infusion to deliver 33 gtt/min.

Correct Answer is D
Explanation
A. Decreased cardiac output is not a primary concern with chlorine exposure, which primarily affects the respiratory system.
B. Hypovolemia is not directly related to chlorine gas exposure. The primary concern is respiratory damage.
C. Chronic pain is not an immediate or primary finding in chlorine gas exposure; the focus is on acute respiratory effects.
D. Pulmonary edema is a common and severe consequence of chlorine gas inhalation due to the corrosive effect of chlorine on the respiratory tract, leading to fluid accumulation in the lungs.
Correct Answer is B
Explanation
A. Drying the sclera with a cotton swab prior to administering eye drops is not recommended and could introduce fibers or cause irritation. Proper eye drop administration does not require drying the sclera.
B. Administering the medications 5 minutes apart is correct because it allows each medication to be absorbed properly, preventing the second drop from washing out the first. This timing helps ensure that both medications are effective.
C. Touching the tip of the dropper to the sclera is incorrect and can introduce contaminants, leading to infection. Eye drops should be administered without the dropper touching the eye to maintain sterility.
D. Holding pressure on the conjunctival sac for 2 minutes is excessive. The recommended practice is to gently press on the nasolacrimal duct for 1-2 minutes after administration to prevent systemic absorption, especially with medications like timolol.
