C. Hyperthyroidism
D. Addison’s
Rationale: Type 1 diabetes requires lifelong insulin therapy.
19. Best position for a patient with dyspnea?
,A. Supine
B. Prone
C. High Fowler’s
D. Trendelenburg
Rationale: Elevates thorax, reducing work of breathing.
20. Which finding is expected for dehydration?
A. Increased BP
B. Weight gain
C. Tachycardia
D. Moist mucous membranes
Rationale: Low volume triggers compensatory high pulse.
21. What is a normal therapeutic INR for patients on warfarin?
A. 0.5–1
B. 1.0–1.5
C. 2–3
D. 4–6
Rationale: INR 2–3 prevents clotting without excessive bleeding.
22. Which lab indicates kidney failure?
A. Low potassium
B. High creatinine
C. Low sodium
D. High calcium
Rationale: Creatinine rises due to impaired renal filtration.
23. Priority treatment for hyperkalemia?
A. Potassium supplements
B. Insulin + glucose
C. Magnesium
,D. Warfarin
Rationale: Insulin shifts potassium into cells, lowering serum levels.
24. Which assessment indicates fluid overload?
A. Flat neck veins
B. Weight loss
C. Crackles in lungs
D. Dry mucous membranes
Rationale: Extra fluid accumulates in lung tissue.
25. What is the first sign of hypoxia?
A. Cyanosis
B. Confusion
C. Bradycardia
D. Hypertension
Rationale: Brain is sensitive to low oxygen, leading to confusion.
26. Which diet is recommended for hypertension?
A. High sodium
B. Keto

Rationale: Thigh muscle is well-developed and safe.
30. Which medication is a loop diuretic?
A. Lisinopril
B. Furosemide
C. Metformin
D. Omeprazole
Rationale: Furosemide removes excess fluid quickly.
31. Which condition is caused by low potassium?
A. Muscle weakness
B. Hypertension
C. Tachypnea
D. Diarrhea
Rationale: Potassium is vital for muscle and cardiac conduction.
32. What is the purpose of heparin?
