A patient with Staphylococcus aureus infection has Cipro 400 mg in 200 mL D5W ordered. The pharmacy recommends that the Cipro be infused at a rate of 200 mg/hr with an IV pump. How many milliliters per hour should the IV pump be programmed for? Whole number.
The Correct Answer is ["100"]
Determine the concentration of the Cipro solution in milligrams per milliliter (mg/mL).
Available dose = 400 mg
Available volume = 200 mL
Concentration (mg/mL) = (Available dose (mg) / Available volume (mL))
= (400 mg / 200 mL)
= 2 mg/mL.
Calculate the flow rate in mL/hr.
Ordered infusion rate = 200 mg/hr
Flow rate (mL/hr) = (Ordered rate (mg/hr) / Concentration (mg/mL))
= (200 mg/hr / 2 mg/mL)
= 100 mL/hr.

Correct Answer is A
Explanation
A. The child: The physical examination should focus primarily on the child, using a holistic approach that considers both physical and emotional needs. The nurse observes the child’s overall appearance, behavior, and physiological responses, ensuring that the assessment is child-centered and developmentally appropriate.
B. The parents: While parents provide valuable health history and emotional support, they are not the focus of the physical exam. Their role is mainly to comfort the child and supply additional background information during the assessment.
C. Chief complaint: Although addressing the chief complaint is important, the physical exam should not be limited to it. A comprehensive examination ensures that all body systems are assessed, identifying potential issues beyond the presenting concern.
D. Developmental age: Developmental age helps guide the approach to the examination, such as communication style and expected milestones, but it is not the main focus. It informs how the nurse interacts with and evaluates the child rather than being the object of the exam itself.
Correct Answer is D
Explanation
A. "It is normal for your bowel movements to be black.": Black stools may indicate gastrointestinal bleeding, a potential adverse effect of ibuprofen. This finding is not normal and should be reported immediately to the healthcare provider.
B. "Take the medication on an empty stomach.": Ibuprofen can irritate the gastric mucosa and increase the risk of ulcers or bleeding. It should always be taken with food or milk to minimize gastrointestinal discomfort and protect the stomach lining.
C. "Add an aspirin to the regimen if you do not get relief right away.": Combining ibuprofen with aspirin increases the risk of gastrointestinal bleeding and does not enhance pain control. Only one NSAID should be used at a time unless specifically prescribed.
D. "Start taking the medication before you first get your period.": NSAIDs like ibuprofen are most effective when started 1–2 days before menstruation or at the onset of symptoms, as they inhibit prostaglandin synthesis, reducing uterine contractions and menstrual pain.
