Core Nursing Explanation
This question tests the
priority nursing intervention for a child on long-term
growth hormone (GH) therapy. The core principle is
Key Point! managing the
subcutaneous (SubQ) injection site to prevent tissue damage and ensure consistent drug absorption over months or years of treatment.
Key Concept Analysis
Growth hormone (Somatropin) is administered via daily subcutaneous injections. The medication is a protein, and repeated injections into the same site can cause
lipodystrophy—either lipoatrophy (loss of subcutaneous fat, causing dents) or lipohypertrophy (buildup of fatty tissue, causing lumps). Both conditions impair drug absorption and are cosmetically concerning for the child. Therefore, a systematic site rotation plan is a fundamental, long-term nursing responsibility.
Answer Rationale
Key Point! Option ② is correct because it directly addresses the most common and preventable complication of long-term subcutaneous hormone therapy.
Rotating injection sites daily is a proactive, evidence-based intervention that maintains tissue integrity, ensures reliable medication absorption, and promotes patient adherence to the treatment regimen. This is a
high-priority, independent nursing action central to the care plan.
Distractor Analysis
- Option ① (Administer in the morning): While some protocols suggest morning administration to mimic the body's natural GH secretion pattern, it is not the most important intervention. Absorption is not significantly affected by timing in this context. The critical issue is where the injection is given, not precisely when.
- Option ③ (Monitor blood glucose only first week): GH can have an anti-insulin effect, potentially raising blood glucose. Monitoring is important, but it is an ongoing assessment, not one limited to the first week. Furthermore, assessment alone is not a higher priority than the active, preventive intervention of site rotation.
- Option ④ (Increase calcium intake): GH therapy stimulates bone growth. Adequate nutrition, including calcium and vitamin D, supports this process, but it is not a specific, direct nursing intervention for GH therapy. It is a general health promotion measure. The question asks for the most important intervention to include in the nursing care plan specifically for this therapy.
Related Concepts
Nursing care for children on GH therapy also includes monitoring growth parameters (height, weight), assessing for side effects (headache, fluid retention, slipped capital femoral epiphysis), and providing extensive family education on injection technique, storage of medication, and psychosocial support.
Concept Summary
| Concept | Key Points |
|---|
| Growth Hormone (Somatropin) | Protein hormone given by daily SubQ injection for GH deficiency. Promotes linear growth. |
| Lipodystrophy | Complication from repeated injections at same site. Includes lipoatrophy (dents) and lipohypertrophy (lumps). Impairs absorption. |
| Site Rotation | Priority nursing intervention. Use abdomen, thighs, upper arms. Rotate systematically (e.g., clock method) to prevent tissue damage. |
| Nursing Priorities | 1. Teach/ensure site rotation. 2. Monitor growth (height velocity). 3. Assess for side effects (e.g., glucose intolerance, intracranial hypertension). |
Side-by-Side Comparison!
| Intervention | Priority Rationale | Why It's Not the Top Priority Here |
|---|
| Rotate Injection Sites | Prevents tissue damage, ensures consistent absorption, directly related to long-term therapy success. | N/A - This is the correct priority. |
| Monitor Blood Glucose | Important for safety (anti-insulin effect). | An assessment, not a direct preventive action. Risk is relatively low in most children. |
| Administer in AM | May align with circadian rhythm. | Convenience/physiology issue, not a safety or efficacy-critical intervention. |
| Increase Calcium | Supports bone health during growth. | General nutritional advice, not a specific, direct nursing intervention for GH therapy administration. |
Anatomy, Physiology & Pharmacology Points
- Physiology: Growth hormone is secreted by the anterior pituitary gland. It stimulates the liver to produce Insulin-like Growth Factor-1 (IGF-1), which promotes growth of bone and tissue.
- Pharmacology: Recombinant human GH (somatropin) is a large protein molecule. It must be given by injection (SubQ or IM) as it would be destroyed in the GI tract. SubQ is the standard route.
- Absorption: Absorption from subcutaneous tissue is consistent when healthy tissue is used. Damaged tissue (lipodystrophy) leads to erratic absorption.
Memory Tips
- Think "ROTATE for GROWTH": To help a child grow, you must ROTATE the injection sites.
- Lipodystrophy = Lumpy or Dented Sites: Visualize what happens without rotation.
- SubQ Rule of Thumb: For any long-term subcutaneous medication (insulin, GH, etc.), site rotation is always a top-tier nursing priority.
High-Frequency NCLEX Topics
NCLEX loves to test
priority-setting and
patient education for chronic conditions and medication administration. Growth hormone therapy combines both:
- Priority Action: Choosing the intervention that prevents harm (lipodystrophy) over one that is merely convenient (timing) or general (nutrition).
- Teaching Focus: NCLEX questions often ask what to teach the parent/child. "Rotate sites daily" is a classic, must-know teaching point.
Watch Out for Question Variations!
- From Intervention to Assessment: "The nurse is assessing a child on GH therapy for 6 months. Which finding requires immediate intervention?" Answer: Palpable, hardened lumps at the injection site (lipohypertrophy).
- From General to Specific Teaching: "The nurse is teaching a parent to administer GH. Which statement by the parent indicates a need for further teaching?" Incorrect statement: "I will give the shot in the same spot on the thigh every day because it's easier for my child."
- Prioritizing Concerns: "A child on GH therapy reports a mild headache. The nurse's priority action is to..." (Assess for other signs of intracranial hypertension—a rare but serious side effect).
