A nurse is preparing to administer ondansetron 0.15 mg/kg IV bolus every 4 hr. The client weighs 41 kg (92 lb). How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

A. Administer an oral rehydration solution: Oral rehydration solutions (ORS) are specifically formulated to replace fluids and electrolytes lost during diarrhea. They are the first-line treatment for mild to moderate dehydration in children with gastroenteritis, helping prevent complications and restore hydration safely.

B. Offer the child 1 cup of chicken broth: While chicken broth provides some fluid, it is not balanced in electrolytes and sodium, and it may be too concentrated in sodium for a preschooler with diarrhea. ORS is more appropriate for correcting dehydration.

C. Encourage the child to eat gelatin: Gelatin is low in electrolytes and protein and does not adequately replace fluids lost from diarrhea. Relying on gelatin alone would not meet the child’s rehydration needs.

D. Initiate a high-carbohydrate diet: High-carbohydrate foods are not recommended during acute diarrhea because they can worsen osmotic diarrhea. Focus should be on fluid and electrolyte replacement rather than high-carbohydrate foods initially.

A. Administer terbutaline subcutaneously as needed for contractions: Terbutaline is a tocolytic used to suppress preterm labor, not to manage preeclampsia or magnesium sulfate therapy. Its use is unrelated to the care of a client receiving magnesium sulfate for seizure prophylaxis.

B. Monitor the client's blood pressure every 2 hr: In severe preeclampsia, blood pressure should be monitored more frequently than every 2 hours—typically every 15–30 minutes initially—because rapid changes can occur, and close monitoring is critical to prevent complications.

C. Place suction equipment at the client's bedside: Magnesium sulfate can cause respiratory depression as a serious adverse effect. Having suction equipment readily available ensures immediate intervention if the client experiences decreased respiratory effort or airway compromise, making this an essential safety measure.

D. Notify the provider of a urinary output of less than 50 mL/hr: While low urine output can indicate magnesium accumulation or renal impairment, the typical threshold for concern is less than 30 mL/hr. Although monitoring output is important, immediate bedside readiness for respiratory support is the priority intervention when administering magnesium sulfate.
