A nurse is preparing to administer potassium 0.4 mEq/kg/hr to a newborn who weighs 6.7 lb. Available is potassium 10 mEq in 0.9% sodium chloride 100 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["12.2"]

To calculate the IV pump setting, first convert the newborn's weight from pounds to kilograms, knowing that 1 pound is equivalent to 0.453592 kilograms. The newborn weighs 6.7 pounds, which is approximately 3.039 kg (6.7 lb * 0.453592 kg/lb). Next, calculate the total amount of potassium needed per hour by multiplying the newborn's weight in kilograms by the prescribed dose: 0.4 mEq/kg/hr * 3.039 kg = 1.2156 mEq/hr. Since the available potassium is 10 mEq in 100 mL, this means there is 0.1 mEq/mL. To find out how many mL/hr to administer, divide the total mEq needed per hour by the concentration: 1.2156 mEq/hr ÷ 0.1 mEq/mL = 12.156 mL/hr. Rounded to the nearest tenth, the IV pump should be set to deliver 12.2 mL/hr.

Correct Answer is C

Explanation

A. Feeling of vaginal fullness is not an expected therapeutic effect of IV oxytocin; it suggests possible bladder distension.
B. Saturating a perineal pad in 1 hour could indicate excessive bleeding, not a therapeutic effect of oxytocin.
C. A firm and midline fundus is the expected therapeutic effect of oxytocin, indicating proper uterine contraction and prevention of postpartum hemorrhage.
D. Lengthening of the umbilical cord is not an expected therapeutic effect of oxytocin; it is unrelated to the medication's action on uterine contraction.

Correct Answer is ["2"]

Explanation

To administer a dose of 5 mg of glyburide when only 2.5 mg tablets are available, the nurse would need to give two tablets. This is because each tablet contains 2.5 mg, and two tablets would equal the prescribed 5 mg dose.
