Following admission for a cardiac catheterization, the nurse is providing discharge teaching to the parents of a 2-year-old toddler with Tetralogy of Fallot. Which instruction should the nurse give the parents if their child becomes pale, cool, and lethargic?

Encourage oral electrolyte solution intake.

Contact their healthcare provider immediately.

Provide a quiet time by holding or rocking the toddler.

Assist the child to a recumbent position.

Answer and Explanation

The Correct Answer is B

Choice A reason: Electrolyte solutions address dehydration but are inappropriate for pale, cool, lethargic symptoms in Tetralogy of Fallot (TOF), indicating a hypercyanotic spell from right-to-left shunting. Urgent medical intervention restores oxygenation, making this inadequate compared to addressing the critical hypoxic episode requiring provider attention.

Choice B reason: Pale, cool, lethargy in TOF signals a hypercyanotic spell, where pulmonary stenosis increases right-to-left shunting, causing cyanosis and hypoxia. Contacting the provider ensures rapid interventions (e.g., oxygen, beta-blockers), preventing cerebral hypoxia or cardiac arrest, addressing the urgent pathophysiological crisis effectively.

Choice C reason: Quiet time by holding or rocking may calm the toddler but does not treat hypoxic spells in TOF, where pale, cool symptoms indicate shunting and hypoxia. Delaying medical intervention risks severe hypoxia, making this less critical than contacting the provider for urgent management.

Choice D reason: A recumbent position worsens TOF’s hypercyanotic spell, increasing venous return and shunting, exacerbating hypoxia. Knee-chest positioning reduces shunting. Contacting the provider is urgent to address pale, cool, lethargic symptoms, ensuring interventions to restore oxygenation, making this position contraindicated.

Correct Answer is C

Explanation

Choice A reason: Dependence is not a primary concern with lithium, a mood stabilizer. Toxicity is critical due to lithium’s narrow therapeutic range, risking severe complications. Dependence is more relevant to other drugs, per psychopharmacology and lithium therapy education standards in nursing.

Choice B reason: Interactions are important but less urgent than toxicity, which can be life-threatening with lithium’s narrow therapeutic index. Toxicity education emphasizes monitoring blood levels to prevent harm, per psychopharmacology and patient safety protocols in lithium therapy teaching.

Choice C reason: Toxicity is the most critical adverse effect to teach, as lithium’s narrow therapeutic index risks severe complications like seizures or renal failure. Monitoring symptoms and blood levels ensures safety, per evidence-based psychopharmacology and patient education protocols for lithium therapy in nursing.

Choice D reason: Tolerance is not a significant issue with lithium, unlike toxicity, which is life-threatening due to its narrow therapeutic range. Teaching toxicity symptoms prioritizes patient safety, per lithium therapy management and psychopharmacological education standards in nursing practice.

A. Administer a PRN narcotic. B. Ask the husband to step out. C. Have delivery table set up. D. Notify rapid response team.

Correct Answer is C

Explanation

Choice A reason: Administering a PRN narcotic at 9 cm dilation is inappropriate, as labor is in transition, nearing delivery. Narcotics risk fetal respiratory depression, crossing the placenta, especially with a stable fetal heart rate (120 beats/minute). Preparing for imminent delivery is critical, prioritizing a safe birth environment over pain relief.

Choice B reason: Asking the husband to leave does not address the client’s advanced labor (9 cm, 100% effaced, frequent contractions). His presence may provide support, and removal could increase distress. Setting up the delivery table is urgent, as birth is imminent, ensuring a sterile, safe environment for delivery.

Choice C reason: At 9 cm dilation, 100% effacement, and contractions every 2 minutes, the client is in transition, with delivery imminent. Setting up the delivery table ensures readiness for vaginal birth, providing a sterile field and equipment, addressing the physiological progression of labor for safe delivery of the newborn.

Choice D reason: Notifying the rapid response team is unnecessary, as the fetal heart rate (120 beats/minute) is normal (110–160), and screaming reflects labor pain. Delivery is imminent, making table setup the priority to facilitate safe birth, avoiding escalation to emergency response for a normal labor progression.
