1. Which mechanism is primarily responsible for edema
formation in congestive heart failure?
A. Increased plasma oncotic pressure
B. Decreased capillary hydrostatic pressure
C. Increased capillary hydrostatic pressure
D. Increased lymphatic drainage
Answer: C. Increased capillary hydrostatic pressure
Rationale: Heart failure increases venous pressure, raising
capillary hydrostatic pressure and promoting movement of fluid
into the interstitial space.
2. Which finding is most characteristic of left-sided heart
failure?
A. Peripheral edema
B. Pulmonary congestion
C. Ascites
D. Hepatomegaly
Answer: B. Pulmonary congestion
Rationale: Left ventricular failure causes blood to back up into
,the pulmonary circulation, producing pulmonary edema and
dyspnea.
3. Right-sided heart failure commonly causes which
manifestation?
A. Pulmonary edema
B. Hemoptysis
C. Peripheral edema
D. Hyperventilation
Answer: C. Peripheral edema
Rationale: Right-sided failure causes systemic venous
congestion, resulting in dependent edema, jugular venous
distention, and hepatic congestion.
4. Which hormone promotes sodium and water retention
during heart failure?
A. Insulin
B. Aldosterone
C. Calcitonin
D. Melatonin
Answer: B. Aldosterone
Rationale: Reduced renal perfusion activates the renin-
angiotensin-aldosterone system, increasing sodium and water
retention.
,5. A major pathophysiologic feature of shock is:
A. Excessive tissue perfusion
B. Inadequate tissue perfusion
C. Increased cellular oxygen availability
D. Increased ATP production
Answer: B. Inadequate tissue perfusion
Rationale: Shock occurs when circulation fails to provide
sufficient oxygen and nutrients to meet cellular demands.
6. Which type of shock results from severe blood loss?
A. Cardiogenic
B. Neurogenic
C. Hypovolemic
D. Anaphylactic
Answer: C. Hypovolemic
Rationale: Hypovolemic shock results from significant loss of
blood or other circulating fluid volume.
7. Cardiogenic shock is most directly associated with:
A. Loss of vascular tone
B. Pump failure
C. Severe dehydration
D. Allergic reaction
, Answer: B. Pump failure
Rationale: Cardiogenic shock occurs when the heart cannot
pump enough blood to maintain adequate tissue perfusion.
8. Which finding is commonly associated with hypovolemic
shock?
A. Bradycardia
B. Warm, flushed skin
C. Tachycardia
D. Increased urine output
Answer: C. Tachycardia
Rationale: The sympathetic nervous system increases heart
rate to compensate for reduced circulating volume.
9. Sepsis can lead to shock primarily through:
A. Excessive insulin secretion
B. Dysregulated systemic inflammatory response
C. Increased bone formation
D. Reduced immune activity only
Answer: B. Dysregulated systemic inflammatory response
Rationale: Severe infection can trigger widespread
inflammation, vasodilation, endothelial dysfunction, and
impaired tissue perfusion.
