The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number.
Use a leading zero if it applies.
Do not use a trailing zero.)
The Correct Answer is ["7"]
Step 1 is (0.1 unit/kg/hr × 70 kg) = 7 units/hr Step 2 is (7 units/hr ÷ 100 units) × 100 mL = 7 mL/hr. Final answer: 7 mL/hr.

Correct Answer is A
Explanation
Choice A rationale
Losartan is an angiotensin II receptor blocker (ARB) used for managing hypertension. However, it is contraindicated during pregnancy and postpartum periods due to the risk of fetal and neonatal toxicity, including renal dysfunction, oligohydramnios, and skull hypoplasia. Clarifying this prescription with the provider is crucial to avoid potential harm to the mother and the newborn.
Choice B rationale
Ferrous fumarate is an iron supplement commonly prescribed to address iron deficiency anemia, which can occur during the postpartum period. It is generally safe and effective for improving hemoglobin levels and replenishing iron stores. Therefore, this prescription does not require clarification with the provider unless there are specific contraindications or concerns related to the client's condition.
Choice C rationale
Docusate sodium is a stool softener frequently prescribed to prevent or treat constipation, which is common postpartum due to hormonal changes and decreased physical activity. It is considered safe and effective for use during the postpartum period, making it unnecessary to clarify this prescription with the provider unless there are specific contraindications or adverse reactions.
Choice D rationale
Prochlorperazine is an antiemetic used to manage nausea and vomiting. It is generally safe for use in the postpartum period when prescribed appropriately. However, clarifying with the provider can ensure that the benefits outweigh any potential risks, especially if there are concerns about the medication’s side effects or interactions with other prescribed drugs.
