CNCC(C) Practice Questions - CNCC(C) Certified Nurse in Critical Care (Canada) Exam - CNCC(C) Practice Questions - CNCC(C) Certified Nurse in Critical Care (Canada) Exam

Question 1

A patient with acute coronary syndrome (ACS) is receiving an intravenous nitroglycerin infusion. Which of the following is the primary therapeutic goal of this medication?

To increase myocardial oxygen demand by dilating coronary arteries. To reduce myocardial oxygen demand by decreasing ventricular preload. To increase systemic vascular resistance to maintain blood pressure. To increase ventricular afterload by dilating peripheral veins.

Correct Answer:

To reduce myocardial oxygen demand by decreasing ventricular preload.

Question 2

A patient in the intensive care unit is exhibiting signs of cardiogenic shock. Which set of hemodynamic parameters is most consistent with this diagnosis?

Decreased Central Venous Pressure (CVP), decreased Pulmonary Artery Wedge Pressure (PAWP), increased Cardiac Index (CI). Increased CVP, increased PAWP, decreased CI, increased Systemic Vascular Resistance (SVR). Decreased CVP, increased PAWP, increased CI, decreased SVR. Increased CVP, decreased PAWP, decreased CI, decreased SVR.

Correct Answer:

Increased CVP, increased PAWP, decreased CI, increased Systemic Vascular Resistance (SVR).

Question 3

An arterial line trace for a patient shows a blood pressure of 90/60 mmHg. What is the calculated Mean Arterial Pressure (MAP), and what is the minimum MAP typically required to maintain adequate organ perfusion?

MAP is 75 mmHg; the minimum required is 60 mmHg. MAP is 70 mmHg; the minimum required is 65 mmHg. MAP is 70 mmHg; the minimum required is 60 mmHg. MAP is 80 mmHg; the minimum required is 70 mmHg.

Correct Answer:

MAP is 70 mmHg; the minimum required is 65 mmHg.

Question 4

A 12-lead ECG reveals ST-segment elevation in leads V1 to V4. Which coronary artery is most likely occluded, and which area of the myocardium is affected?

Right coronary artery (RCA); inferior wall. Left anterior descending (LAD) coronary artery; anterior wall. Left circumflex (LCx) coronary artery; lateral wall. Posterior descending artery (PDA); posterior wall.

Correct Answer:

Left anterior descending (LAD) coronary artery; anterior wall.

Question 5

A patient is supported by an intra-aortic balloon pump (IABP) for cardiogenic shock. During your assessment, you note that the timing waveform shows 'late inflation' of the balloon. What is the primary physiological consequence of late inflation?

Premature closure of the aortic valve and increased left ventricular afterload. Decreased coronary artery perfusion and suboptimal diastolic augmentation. Increased risk of aortic dissection due to high pressure during systole. Retrograde blood flow into the left ventricle causing pulmonary edema.

Correct Answer:

Decreased coronary artery perfusion and suboptimal diastolic augmentation.
