0.45% Sodium Chloride (Hypotonic): Has lower osmolarity than blood, causing fluid to shift into cells, making them swell. Used for dehydration and intracellular rehydration.

0.9% Sodium Chloride (Isotonic): Has the same osmolarity as blood, so it stays in the intravascular space. Used for fluid resuscitation (hypovolemia, dehydration, shock).

Lactated Ringers (Isotonic): Contains electrolytes (Na+, K+, Ca2+, lactate), making it ideal for burns, surgery, and trauma patients. Maintains intravascular volume without fluid shifts.

Albumin (Hypertonic): Large protein that pulls fluid into the intravascular space (colloid osmotic pressure). Used for hypovolemia, burns, or severe hypoalbuminemia.

Correct Answer is ["A","B","D","E","G"]

Explanation

A. Abdomen rigid with decreased bowel sounds: A rigid, tender abdomen suggests peritonitis, a life-threatening complication of peritoneal dialysis requiring immediate intervention.

B. Glucose 220 mg/Dl: Elevated glucose is concerning but not immediately life-threatening compared to the other findings.

C. No dialysis for 24 hours: Missing dialysis leads to toxin accumulation, hyperkalemia, and fluid overload, all of which can be life-threatening.

D. Crackles throughout the lungs: Fluid overload can cause pulmonary edema, leading to respiratory distress. Immediate intervention is needed to prevent respiratory failure.

E. WBC 17,000 mm³: Leukocytosis suggests infection, possibly peritonitis, which requires urgent antibiotic therapy.

F. Hemoglobin 10 g/dL: Mild anemia is expected in CKD and not an emergency.

G. Potassium 7 mEq/L: Severe hyperkalemia is a medical emergency due to the risk of life-threatening cardiac arrhythmias.

H. Creatinine 3 mg/dl: Creatinine is chronically elevated in CKD and not an acute concern.

Correct Answer is D

Explanation

A. Diphenhydramine: An antihistamine used for motion sickness, but not first-line for severe nausea and dehydration.

B. Famotidine: A histamine-2 blocker used for acid reflux, not nausea control.

C. Omeprazole: A proton pump inhibitor for acid suppression, not for nausea and vomiting.

D. Ondansetron: Ondansetron (Zofran) is a serotonin (5-HT3) receptor antagonist that is highly effective for nausea and vomiting, especially in dehydration and severe vomiting.
