Answers & Detailed Rationales
Question 1
What is the normal range for Pulmonary Artery Occlusion
Pressure (PAOP)?
A) 2-8 mmHg
B) 5-12 mmHg
C) 10-18 mmHg
D) 15-25 mmHg
Correct Answer: B) 5-12 mmHg
Rationale: PAOP (also called pulmonary capillary wedge pressure
or PCWP) reflects left atrial pressure and left ventricular end-
diastolic pressure. Normal values are 5-12 mmHg. Elevated PAOP
indicates left heart failure or fluid overload, while low values
suggest hypovolemia.
Question 2
,The nurse observes that the patient's jugular veins distend in
the semi-upright position to more than 5 cm above the
sternal angle. This is an indication of:
A) Dehydration
B) Fluid volume overload
C) Hypovolemic shock
D) Normal finding
Correct Answer: B) Fluid volume overload
Rationale: Jugular venous distention (JVD) greater than 5 cm
above the sternal angle in a semi-upright position indicates
increased central venous pressure, which is a sign of fluid volume
overload or right-sided heart failure. The jugular veins reflect
pressure in the right atrium.
Question 3
The resistance against which the left ventricle must pump to
eject its volume is:
A) Pulmonary vascular resistance
B) Systemic vascular resistance
, C) Preload
D) Contractility
Correct Answer: B) Systemic vascular resistance
Rationale: Systemic vascular resistance (SVR) is the resistance
against which the left ventricle must work to eject blood into the
systemic circulation. It is also known as afterload for the left
ventricle. Increased SVR (as in hypertension) increases myocardial
workload.
Question 4
When the tricuspid valve is open, central venous pressure
reflects the filling pressure in the:
A) Left atrium
B) Left ventricle
C) Right ventricle
D) Pulmonary artery
Correct Answer: C) Right ventricle
Rationale: When the tricuspid valve is open during diastole, the
right atrium and right ventricle are in direct communication.
Therefore, central venous pressure (CVP) reflects the filling
