A nurse is preparing to administer ceftriaxone 1 g intermittent IV bolus to a client over 30 min. Available is ceftriaxone 1 g in 100 mL of dextrose 5% in water. The nurse should set the pump to deliver how many mL per hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["200"]

Total volume to infuse = 100 mL

Infusion time = 30 minutes

  • Convert infusion time to hours:

1hr = 60 minutes

30 minutes / 60 minutes/hour = 0.5 hours

  • Calculate the infusion rate in mL per hour:

Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hours)

           = 100 mL / 0.5 hours

           = 200 mL/hr

Correct Answer is C

Explanation

A. 1+ pedal edema. Mild pedal edema is typically not associated with instability or falls, unless it progresses to severe swelling that affects mobility or balance. It is a sign of fluid retention but not a direct fall risk indicator on its own.
B. Bruises on the lower extremities. Bruising can be a sign of previous falls or trauma, but it is not itself a cause or indicator of fall risk. While it may prompt further investigation, it does not confirm fall risk independently.
C. Impaired vision. Visual impairment is a significant risk factor for falls because it affects depth perception, ability to detect hazards, and overall spatial awareness. Clients with impaired vision are more likely to trip, misjudge steps, or bump into obstacles.
D. Coarse rhonchi auscultated over the trachea. Coarse rhonchi are respiratory findings typically related to mucus in the airways and do not directly contribute to fall risk unless accompanied by severe respiratory distress or fatigue.

Explanation

  • Prolonged rupture of membranes: Rupture of membranes lasting longer than 18 hours increases the risk of ascending bacterial infection, leading to conditions such as endometritis. This is a known risk factor for postpartum infection, especially following cesarean delivery.
  • Polyhydramnios: An excessive amount of amniotic fluid overdistends the uterus, which can impair its ability to contract effectively postpartum, making uterine atony more likely. Atony can lead to increased bleeding or retained lochia.
  • Prenatal anemia: While not directly causing infection, anemia impairs immune function, increasing a person's susceptibility to postpartum infections. It can also worsen recovery from infections or surgical wounds.
  • High parity: Multiple prior pregnancies stretch the uterus over time, reducing myometrial tone, which predisposes to uterine atony. This makes it harder for the uterus to contract adequately after delivery, increasing the risk for hemorrhage or subinvolution.
