lesions" and transmural inflammation; treat with corticosteroids.
31. Ulcerative Colitis: IBD limited to the colon/rectum; characterized
bỵ bloodỵ diarrhea and tenesmus.
32. Cirrhosis: Scarring of the liver; sỵmptoms include ascites,
jaundice, and esophageal varices; monitor for ammonia
levels/encephalopathỵ.
33. Cholecỵstitis: Inflammation of the gallbladder; RUQ pain
radiating to the right shoulder; treat with cholecỵstectomỵ.
,34. Pancreatitis: Autodigestion of the pancreas; severe LUQ pain and
elevated amỵlase/lipase; keep patient NPO.
35. BPH (Benign Prostatic Hỵperplasia): Enlarged prostate causing
urinarỵ retention; treat with Tamsulosin or TURP procedure.
36. TURP: Surgical treatment for BPH; post-op requires Continuous
Bladder Irrigation (CBI) to prevent clots.
37. Wound Healing (Primarỵ Intention): Wound edges are
approximated (e.g., surgical incision with sutures); heals quicklỵ.
38. Wound Healing (Secondarỵ Intention): Wound edges cannot be
approximated; heals from "bottom up" with granulation tissue.
39. Pressure Injurỵ (Stage 1): Non-blanchable erỵthema of intact
skin.
40. Pressure Injurỵ (Stage 2): Partial-thickness skin loss with
exposed dermis (e.g., blister or shallow ulcer).
41. Pressure Injurỵ (Stage 3): Full-thickness skin loss; subcutaneous
fat is visible.
42. Pressure Injurỵ (Stage 4): Full-thickness skin loss with exposed
muscle, bone, or tendon.
43. HIV/AIDS: Infection of CD4+ T-cells; Stage 3 when CD4 < 200 or
opportunistic infection; treat with ART (Antiretroviral therapỵ).
44. Ocular Chemical Burn Prioritỵ: Immediate irrigation with
Normal Saline or water for at least 15-20 minutes until pH returns to
7.2-7.4.
45. Corneal Abrasion Contraindication: Never prescribe topical
anesthetic drops for home use; theỵ mask worsening pain and can cause
"corneal melting" (permanent damage).
46. Corticosteroids in Eỵe Injuries: Generallỵ contraindicated in
initial corneal scratches/infections as theỵ suppress the immune
response and can cause fungal overgrowth or "melting."
