A nurse is preparing to administer atenolol 50 mg PO daily to a client. The amount available is atenolol 100 mg/tablet. How many tablets should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)
The Correct Answer is ["0.5"]
To calculate the number of tablets, the nurse should use the following formula:
Number of tablets = (Desired dose / Available dose) x (Available form / Desired form)
In this case, the desired dose is 50 mg, the available dose is 100 mg, the available form is 1 tablet, and the desired form is 1 tablet. Therefore, the formula becomes:
Number of tablets = (50 mg / 100 mg) x (1 tablet / 1 tablet)
Number of tablets = 0.5 x 1
Number of tablets = 0.5
The nurse should round the answer to the nearest tenth, which is 0.5. The nurse should use a leading zero if the answer is less than 1, which is 0.5. The nurse should not use a trailing zero, which means 0.5 and not 0.50.

Correct Answer is C
Explanation
Choice A reason: Tampons are not safe to use to absorb the leaking amniotic fluid, because they can introduce bacteria into the vagina and uterus, and increase the risk of infection and preterm labor. The nurse should instruct the client to use sanitary pads instead, and change them frequently.
Choice B reason: Reporting a temperature less than 37 degrees C is not a necessary activity, because it is a normal finding and does not indicate any complication. The nurse should instruct the client to report a temperature greater than 37.8 degrees C, which can be a sign of infection or chorioamnionitis.
Choice C reason: Not engaging in sexual activity is a recommended activity, because it can help prevent further rupture of membranes, infection, and preterm labor. The nurse should instruct the client to avoid any vaginal or cervical stimulation, such as intercourse, douching, or tampon use.
Choice D reason: Taking frequent tub baths is not a safe activity, because it can expose the vagina and uterus to contaminated water, and increase the risk of infection and preterm labor. The nurse should instruct the client to take showers instead, and avoid submerging the lower body in water.
Correct Answer is ["117"]
Explanation
The correct answer is 117 mL/hr.
To calculate the IV rate, the nurse should use the following formula:
IV rate (mL/hr) = (Volume to be infused (mL) / Time of infusion (hr)) x Drop factor (gtt/mL)
In this case, the volume to be infused is 350 mL, the time of infusion is 3 hr, and the drop factor is 1 gtt/mL (assuming the IV pump is calibrated in mL/hr). Therefore, the formula becomes:
IV rate (mL/hr) = (350 mL / 3 hr) x 1 gtt/mL
IV rate (mL/hr) = 116.67 mL/hr
The nurse should round the answer to the nearest whole number, which is 117 mL/hr.
