A nurse is caring for a 2-week-old infant diagnosed with congenital adrenal hyperplasia (CAH). The parents are being educated about long-term management. Which nursing intervention is most important for preventing adrenal crisis?

Adrenal crisis prevention in CAH requires stress dose management of glucocorticoid replacement therapy. Other options focus on less critical aspects or are incorrect.

Core Nursing Explanation Key Concept Analysis: This question tests the critical nursing intervention for preventing adrenal crisis in an infant with Congenital Adrenal Hyperplasia (CAH). CAH is a genetic disorder where the adrenal glands cannot produce sufficient cortisol and often aldosterone. The cornerstone of management is lifelong glucocorticoid (hydrocortisone) replacement therapy. The greatest danger is an adrenal crisis, a life-threatening condition triggered by physical stress (e.g., illness, fever, injury, surgery), where the body's demand for cortisol exceeds the replacement dose.

Answer Rationale: Key Point! The most important intervention is educating parents to increase the hydrocortisone dosage during times of stress. This "stress dosing" mimics the body's normal physiological response, where the adrenal glands would naturally secrete more cortisol. Failing to do so can rapidly lead to adrenal crisis, characterized by vomiting, dehydration, hypoglycemia, hypotension, shock, and death. This education empowers parents to be the first line of defense in preventing a medical emergency.

Distractor Analysis: Watch out for confusion!
• Option ②: While monitoring daily weight is a good practice to assess growth and fluid status, strict fluid restrictions are not standard for CAH. In fact, during illness, infants with salt-wasting CAH may need increased fluids and electrolytes. This option combines a correct action with an incorrect one.
• Option ③: This is dangerously incorrect. Mineralocorticoid replacement (e.g., fludrocortisone) is typically a daily, maintenance medication for the salt-wasting form of CAH to prevent sodium loss and hyperkalemia. Waiting for signs of dehydration means treatment is reactive, not preventive, and puts the infant at high risk.
• Option ④: This is a critical error. Medications for CAH are lifelong. Abruptly or gradually discontinuing them, even when the child appears well, will lead to adrenal insufficiency and can precipitate an adrenal crisis. Parents must understand that the medication replaces a vital hormone the body cannot make.

Related Concepts: Adrenal crisis prevention hinges on the principle of stress-dose steroids. This applies not only to CAH but to any condition requiring long-term glucocorticoid therapy (e.g., Addison's disease). Parental education must be clear, reinforced, and include a written "sick-day plan."

Nursing Clinical Practice Guide Clinical Scenario: You are a pediatric nurse in an outpatient clinic. The parents of baby Mia, diagnosed with salt-wasting CAH at birth, return for a 2-week follow-up. Mia is on daily oral hydrocortisone and fludrocortisone. The mother mentions Mia has a mild runny nose but is feeding well.

Nursing Intervention Strategy: 1. Assessment: Immediately assess for subtle signs of impending crisis: Is Mia feeding less? Any vomiting? Is she more sleepy or irritable? Check weight trend since last visit. Review the parents' understanding of medication administration. 2. Education & Planning: Use this "teachable moment." Praise the parents for bringing her in. Provide a concrete, written "Sick-Day Plan": • Mild illness (fever >38.5°C/101.3°F, poor feeding, vomiting): Double or triple the daily hydrocortisone dose. Give in divided doses every 8 hours. • Severe illness/vomiting that prevents oral intake: This is an emergency. Instruct parents to administer the prescribed hydrocortisone injection (IM) and go to the ER immediately. Emphasize "Never wait." • Reinforce that fludrocortisone dose usually stays the same, but during gastroenteritis with diarrhea, a temporary increase may be needed per endocrinologist's advice. 3. Implementation & Evaluation: Have the parents verbalize back the plan. Provide an emergency letter/bracelet stating Mia's diagnosis and need for stress-dose steroids. Schedule a follow-up call in 2 days to check on Mia's status.

Patient Safety and Precautions: The biggest safety risk is parental hesitation to increase steroids. Emphasize that overtreating with an extra dose of hydrocortisone for a few days is far safer than risking an adrenal crisis. Ensure parents have injectable hydrocortisone at home and know how to use it.
Nursing Procedure & Medication Flow Parental Education for Stress Dosing: • When? Fever, infection, injury, emotional stress, surgery, vomiting/diarrhea. • How Much? Typically 2-3 times the daily maintenance dose. Always follow the specific written protocol from the endocrinology team. • Route? Oral if tolerated. If vomiting, use intramuscular (IM) injection. Do not delay. • Documentation: Teach parents to log the illness, doses given, and the infant's response.
A Word from Your Senior Nurse "Managing CAH is a marathon, not a sprint. Your role is to equip these parents with the confidence and knowledge to act decisively. In the hospital, we see the terrifying consequences of adrenal crisis—it's preventable. Your thorough teaching on stress dosing is literally lifesaving. Remember, parents are your partners. When they understand the 'why'—that their child's body can't respond to stress—they become empowered caregivers. This is the essence of family-centered nursing care."
