NCLEX-PN adult health: medical-surgical nursing within LPN/LVN scope
Adult health is the largest content domain on the NCLEX-PN, covering physiological integrity across medical and surgical settings. The LPN/LVN role focuses on data collection, established care plan implementation, basic nursing care delivery, and accurate reporting of significant changes to the supervising RN or provider.
Educational purpose: This content is for exam preparation and professional development only. It is not intended for clinical decision-making. Always follow current guidelines, institutional policies, and scope of practice.
Cardiovascular nursing — data collection and care within PN scope
Heart failure: LPN/LVN collects data: daily weight, intake/output, lung sounds (crackles indicate fluid accumulation), peripheral oedema assessment, and vital signs. Report weight gain >1 kg/day or >2.3 kg/week, new or worsening dyspnoea, and increasing oedema to the supervising RN immediately. Administer prescribed diuretics; monitor urine output and electrolytes. Reinforce dietary teaching: sodium and fluid restriction.
Post-myocardial infarction care: Activity progression per cardiac rehabilitation protocol, vital signs monitoring, pain assessment (nitroglycerin for stable angina per protocol), ECG changes reporting, and medication administration (antiplatelet agents, beta-blockers, statins, ACE inhibitors). Teach pulse monitoring and when to seek emergency care.
Hypertension management: BP monitoring per ordered schedule, medication administration (antihypertensives — hold if systolic <90 or per protocol), patient teaching on medication adherence, sodium restriction, activity, smoking cessation, and weight management.
Respiratory conditions — COPD, pneumonia, and airway management
COPD exacerbation care: Positioning (high Fowler's), low-flow oxygen administration (target SpO2 88–92% in CO2 retainers), bronchodilator administration per order, sputum characteristics assessment, encourage oral hydration, breathing exercises (pursed-lip, diaphragmatic). Report increasing respiratory distress, declining SpO2, or confusion to RN immediately.
Post-surgical respiratory care: Incentive spirometry every 1–2 hours while awake (turn, cough, deep breathe), early ambulation, assess breath sounds every 4 hours, position 30–45° HOB to reduce aspiration risk. Splinting incision during coughing reduces pain and improves effectiveness.
Tracheostomy care: LPN/LVN scope includes routine tracheostomy care — suctioning, inner cannula cleaning, and dressing changes per protocol. Report: increased secretion volume or character change, cuff pressure concerns, bleeding around the stoma, or respiratory distress.
Diabetes mellitus — monitoring, insulin administration, and hypoglycaemia
Diabetes is one of the most frequently tested conditions on NCLEX-PN. LPN/LVN competencies include: glucose monitoring, insulin administration, recognition of hypo- and hyperglycaemia, and patient teaching.
Hypoglycaemia recognition and intervention: Symptoms: shakiness, diaphoresis, pallor, tachycardia, confusion, headache. Mild (conscious, can swallow): 15 g fast-acting carbohydrate (4 oz juice, glucose tablets). Recheck in 15 minutes. If still <70 mg/dL — repeat. If unable to swallow: glucagon injection (IM/SQ) or notify RN for IV dextrose. Document and report episode.
Hyperglycaemia monitoring: Elevated blood glucose, polyuria, polydipsia, polyphagia, blurred vision. In hospital: report glucose >180–250 mg/dL (per institutional protocol) for sliding-scale insulin administration. Report signs of DKA (Kussmaul respirations, acetone breath, vomiting) or HHS (extreme dehydration, altered mental status) to RN immediately.
Frequently asked questions
- What is the LPN/LVN's responsibility when a patient's condition changes acutely?
- The LPN/LVN's primary responsibility is to (1) immediately assess and collect data on the acute change, (2) notify the supervising RN using SBAR communication — Situation (what is happening), Background (relevant history), Assessment (what the LPN/LVN observes), Recommendation (what assistance is needed). The LPN/LVN implements immediate basic life support or first-response measures (oxygen, positioning, call light response) while awaiting RN assessment. The RN then conducts the comprehensive nursing assessment and determines the care plan change. The LPN/LVN should never delay reporting a significant change to 'gather more information first' unless the patient is in immediate danger requiring first-response action.
