A newborn who weighs 4300 grams is receiving ampicillin 2mg/kg IV once per day.
The vial reads 20mg/mL. How much will the nurse draw up in the syringe for one dose?
(Enter your answer in numbers only. No units.)
The Correct Answer is ["0.43"]
Step 1 is to calculate the total dose required: 4300 g × (2 mg ÷ 1000 g) = 8.6 mg.
Step 2 is to calculate the volume to draw up: 8.6 mg ÷ (20 mg ÷ 1 mL) = 0.43 mL. Final answer: 0.43 mL. .

Correct Answer is A
Explanation
Choice A rationale
Dyspnea, or difficulty breathing, is a serious adverse effect of terbutaline that should be reported to the provider. Terbutaline can cause bronchospasm and pulmonary edema, leading to respiratory distress.
Choice B rationale
Headaches are a common side effect of terbutaline but are not considered a serious adverse effect that requires immediate reporting to the provider.
Choice C rationale
Nervousness is a common side effect of terbutaline and is usually mild. It does not require immediate reporting to the provider unless it becomes severe.
Choice D rationale
Tremors are a common side effect of terbutaline and are usually mild. They do not require immediate reporting to the provider unless they become severe.
Correct Answer is D
Explanation
Choice A rationale
A temperature of 37.8°C (100.3°F) is a low-grade fever that does not typically indicate a serious issue in the context of epidural analgesia during labor. It should be monitored, but it's not immediately concerning.
Choice B rationale
Generalized itching can be a common side effect of epidural analgesia due to the opioids used. It should be monitored and managed, but it does not typically require immediate physician notification.
Choice C rationale
Weakness of the lower extremities can be expected with epidural analgesia as it causes a loss of sensation and muscle control. This should be monitored, but it is not typically an emergency.
Choice D rationale
Fetal bradycardia is a serious concern that must be reported to the physician immediately. It can indicate fetal distress and requires urgent evaluation and intervention to ensure the well-being of the baby. .
