A nurse is planning care for a client who is at 31 weeks of gestation and has preeclampsia with severe features. The client has a new prescription for magnesium sulfate via continuous IV infusion. Which of the following actions should the nurse plan to take?
Administer calcium gluconate for urine output less than 50 mL/hr.
Check deep tendon reflexes every 8 hr
Administer one dose of betamethasone now and repeat in 24 hr.
Limit IV intake to no more than 200 mL/hr.
The Correct Answer is C
A. Administer calcium gluconate for urine output less than 50 mL/hr: Calcium gluconate is given to treat magnesium sulfate toxicity, which is indicated by absent deep tendon reflexes, respiratory depression, or high serum magnesium levels. Low urine output requires monitoring but does not automatically warrant calcium gluconate administration.
B. Check deep tendon reflexes every 8 hr: Deep tendon reflexes should be assessed frequently during magnesium sulfate therapy, usually every 1–2 hours, to detect early signs of toxicity. Checking only every 8 hours is insufficient for safe monitoring.
C. Administer one dose of betamethasone now and repeat in 24 hr: Betamethasone is given to accelerate fetal lung maturity in preterm gestation, which is critical at 31 weeks. Administering the two-dose course as prescribed helps reduce neonatal respiratory complications, making this a priority intervention alongside magnesium sulfate therapy.
D. Limit IV intake to no more than 200 mL/hr: Monitoring and limiting IV fluids helps prevent fluid overload and pulmonary edema in preeclamptic clients, but ensuring fetal lung maturity with betamethasone takes priority at this gestational age in case of an early delivery.

Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"B"}
Explanation
Rationale for correct choices
• Inspect the child’s oropharynx: The child has bright red emesis and visible bleeding in the posterior pharynx, which indicates active post-tonsillectomy hemorrhage. Direct visualization helps confirm the bleeding source and severity. Early inspection supports rapid intervention because post-operative tonsillar bleeding can progress quickly and become life-threatening.
• Obtaining a set of vital signs: Active bleeding and vomiting bright red blood require immediate reassessment of vital signs to detect tachycardia, hypotension, or respiratory compromise. Hemoglobin and hematocrit are already low, increasing the child’s risk for hemodynamic instability. Timely vital signs guide urgent decisions about fluid resuscitation and notifying the provider.
Rationale for incorrect choices
• Offer the child a red popsicle: Providing red-colored fluids can mask ongoing bleeding and delay recognition of hemorrhage. The priority is to assess and stabilize the child with known bleeding, not to offer oral intake. This intervention risks obscuring the color of emesis or oral bleeding.
• Place the child in a supine position: Supine positioning increases the risk of aspiration when bleeding or vomiting is present. The child should be maintained upright to allow drainage and airway protection. Supine positioning does not address the current complication and may worsen respiratory safety.
• Encouraging the child to cough and deep breathe: Coughing can dislodge clots and worsen post-tonsillectomy bleeding. The child already has active bright red bleeding, so stimulating airway pressure would increase hemorrhage risk. This intervention is inappropriate in immediate postoperative bleeding scenarios.
• Requesting a prescription for codeine: Codeine is contraindicated in children after tonsillectomy due to risk of respiratory depression from ultra-rapid metabolism. Pain is mild, and bleeding—not pain—is the priority. Requesting codeine does not address the current danger of hemorrhage.
Correct Answer is D
Explanation
A. Remove the surgical dressing and obtain a culture: Removing the dressing immediately is unnecessary for routine serosanguineous drainage, which is a normal finding in the early postoperative period. Cultures are only indicated if there are signs of infection such as purulent drainage, redness, or odor.
B. Irrigate the incision with saline: Irrigation is not required for normal serosanguineous drainage and may disrupt the healing process. It is reserved for wounds with debris, infection, or specific provider orders.
C. Clean the wound with hydrogen peroxide: Hydrogen peroxide can damage healthy tissue and delay healing. It is not indicated for routine postoperative care and should be avoided for normal drainage.
D. Mark the outline of the drainage: Marking the outline of the drainage allows the nurse to monitor for changes in amount and size over time. Tracking progression helps identify potential complications such as excessive bleeding or infection and supports timely interventions.
