During the second stage of labor, the fetal head has just been born and the nurse observes the immediate retraction of the head against the perineum.
What action should the nurse anticipate performing to assist the healthcare provider?
Prepare vacuum.
Apply suprapubic pressure.
Apply fundal pressure.
Prepare forceps.
Prepare forceps.
The Correct Answer is B
Choice A rationale
Preparing a vacuum is not the first action to take when the fetal head retracts against the perineum during the second stage of labor.
Choice B rationale
Applying suprapubic pressure can help guide the baby’s head out. This is a common practice during the second stage of labor when the baby’s head retracts against the perineum.
Choice C rationale
Applying fundal pressure is not typically done when the fetal head retracts against the perineum. Fundal pressure can be used to assist in the delivery of the baby, but it’s not the first action to take in this situation.
Choice D rationale
Preparing forceps is not the first action to take when the fetal head retracts against the perineum. Forceps are used to assist in the delivery of a baby, but only when necessary.

Correct Answer is B
Explanation
Choice A rationale
Preparing a vacuum is not the first action to take in this situation. A vacuum-assisted delivery might be considered in some cases, but it’s not the immediate action when the fetal head retracts against the perineum.
Choice B rationale
Applying suprapubic pressure is the correct action. This situation describes shoulder dystocia, where the baby’s shoulder gets stuck behind the mother’s pelvic bone during delivery. Suprapubic pressure can help dislodge the baby’s shoulder and allow the delivery to proceed.
Choice C rationale
Applying fundal pressure is not recommended in this situation. Fundal pressure could potentially worsen shoulder dystocia and is generally avoided.
Choice D rationale
Preparing forceps is not the immediate action to take. Forceps may be used in some delivery situations, but in the case of shoulder dystocia, other maneuvers are tried first.
Correct Answer is ["25"]
Explanation
Answer and explanation
Step 1 is to convert the child’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.2 lbs. So, the child’s weight in kg is 55 lbs ÷ 2.2 = 25 kg (rounded to the nearest whole number for simplicity).
Step 2 is to calculate the total daily dosage. The prescription is for isoniazid 10 mg/kg/day. So, the total daily dosage in mg is 10 mg/kg/day × 25 kg = 250 mg/day.
Step 3 is to calculate the volume of the oral solution to administer. The bottle is labeled, “Isoniazid Oral Solution, USP 50 mg per 5 mL.”. So, the volume in mL to administer is (250 mg/day ÷ 50 mg) × 5 mL = 25 mL. Therefore, the nurse should administer 25 mL of the Isoniazid Oral Solution, USP 50 mg per 5 mL, once a day.
