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. By the first birthday: The American Academy of Pediatric Dentistry recommends that a child’s first dental visit occur by age one or within six months of the first tooth eruption. Early dental care promotes proper oral hygiene, identifies early signs of decay, and helps parents learn preventive strategies.
B. By the second birthday: Waiting until the second birthday delays opportunities for early intervention and education on oral hygiene habits. Tooth decay can develop soon after eruption, so a visit by age one is preferred.
C. By entry into kindergarten: This age is far too late for a first dental visit. By this time, early childhood caries could already have developed, requiring more extensive dental care and increasing the risk of oral health complications.
D. By entry into first grade: A dental visit at this age misses critical preventive care in early childhood. The primary teeth play an important role in chewing, speech development, and alignment of permanent teeth, which need early monitoring.
Correct Answer is B
Explanation
A. Amenorrhea: Uterine fibroids are more commonly associated with menorrhagia (heavy bleeding) or metrorrhagia (irregular bleeding) rather than amenorrhea. Fibroids cause increased uterine lining surface area and vascular congestion, leading to excessive rather than absent menstrual flow.
B. Chronic pelvic pain: Chronic pelvic pain or a feeling of pelvic pressure is a classic symptom of uterine fibroids. The enlarging fibroids can compress surrounding structures, causing discomfort, lower abdominal fullness, and sometimes radiating pain to the lower back or thighs.
C. Upper back pain: Fibroids are located in the uterus, within the pelvic cavity, and are unlikely to cause upper back pain. Pain from fibroids typically presents in the lower abdomen or pelvis due to localized pressure.
D. Diarrhea: Gastrointestinal symptoms like diarrhea are not typically associated with fibroids. If present, bowel symptoms are more likely due to large fibroids exerting pressure on the rectum, leading to constipation rather than increased bowel motility.
