Conditions | Actual Study with Complete Solutions | 2026
Updates | 100% correct
Cardiac & Vascular
- Heart Attack vs Chest Pain:
•MI (Heart Attack) : Radiating pain, unrelieved by rest/nitro, N/V,
diaphoresis.
•Angina (Chest Pain): Triggered by exertion, relieved by rest/nitro.
- DVT (NGN Scenario):
•Symptoms: Unilateral leg swelling, warmth, pain.
•Interventions: Anticoagulants, no massage, elevate leg.
- Cardiac Medications:
•Beta-blockers: Lower HR/BP.
•ACE inhibitors: Lower BP, watch for cough.
•Diuretics: Reduce fluid overload.
•Calcium channel blockers: Lower BP, treat arrhythmias.
•SIADH = Fluid Retention
• Hyponatremia, low urine output, weight gain, confusion.
Neuro & Endocrine
- Cushing Disease:
•Moon face, hyperglycemia, buffalo hump. -
Graves Disease:
•Weight loss, heat intolerance, exophthalmos. -
Bacterial Meningitis:
, lOMoAR cPSD| 61371432
•Fever, nuchal rigidity, photophobia. -
Cervical Injury:
•Stabilize spine, monitor breathing. -
Disinhibition:
•Impulse control loss, frontal lobe damage.
Musculoskeletal
- Rheumatoid Arthritis (NGN):
•Symmetrical joint pain, •morning
stiffness >30 mins.
- Osteomalacia:
•Bone pain,
•fractures due to vitamin D deficiency. Postoperative
& Surgical
- Post-Amputation (NGN):
•Phantom pain, prevent contractures, monitor stump.
- Post-TURP:
•CBI, pink urine, monitor for clots. -
Post-Nephrotomy:
•Monitor for bleeding, dont clamp nephrostomy tube.
- Post-Lithiasis:
•Strain urine, increase fluids. -
Post-Cataract:
•Avoid bending, lifting, eye rubbing. -
Open-Angle Glaucoma:
•Gradual vision loss, lifelong eye drops.
GI & Renal
