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.)
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 B
Explanation
A. "Administer this medication as needed for symptom control." Fluticasone is an inhaled corticosteroid used for long-term control, not for acute symptom relief. It should be administered on a regular schedule, not as needed.
B. "Rinse mouth and gargle with water after each use." Rinsing the mouth helps prevent oral thrush (candidiasis), a common side effect of inhaled corticosteroids like fluticasone. It reduces residual medication in the mouth and supports good oral hygiene.
C. “Administer this medication before any other inhaled medications.” Fluticasone should be given after bronchodilators, such as albuterol, if both are prescribed. Administering a bronchodilator first opens the airways and allows the corticosteroid to work more effectively.
D. "Growth may be accelerated while using this medication?” Inhaled corticosteroids may cause slowed growth in some children with long-term use, though the effect is generally small and outweighed by the benefits of asthma control.
Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"E"}
Explanation
- Tocolytic medication: Tocolytics are used to suppress preterm labor, which is not applicable for this postpartum client. There is no indication of uterine contractions needing suppression.
- Intravenous antibiotic: The client exhibits signs of postpartum endometritis—including fever, uterine tenderness, foul-smelling lochia, and a very high WBC count (33,000/mm³). These findings strongly support the need for IV antibiotics to treat the infection.
- Intrauterine tamponade balloon: This device is used for managing postpartum hemorrhage, which is not present in this case. The client’s lochia is moderate, not excessive, and her uterus is responding to massage.
- Kleihauer-Betke test: This test is used to detect fetal-to-maternal hemorrhage, particularly in Rh-negative mothers after trauma or potential placental separation. It is not relevant in the context of postpartum infection.
- Increase in daily fluid intake: The client is febrile and shows signs of systemic infection. Increased fluids support hydration, promote recovery, and help manage the effects of fever and infection, making this an appropriate supportive measure.
