Question 1

What is the correct sequence of ECG?&#10;A) PSRTQ&#10;B) PQRST&#10;C) RSTPQ&#10;D) STPQR

Accepted Answer

B

Question 2

The correct sequence of the valves as blood flows through the heart is ______&#10;A) Tricuspid; Pulmonary; Mitral; Aortic&#10;B) Mitral; Pulmonary; Aortic; Tricuspid&#10;C) Pulmonary; Tricuspid; Mitral; Aortic&#10;D) Aortic; Mitral; Pulmonary; Tricuspid

Accepted Answer

The correct sequence of valves as blood flows through the heart starts with the tricuspid valve (between the right atrium and right ventricle), followed by the pulmonary valve (leading to the pulmonary artery), then the mitral valve (between the left atrium and left ventricle), and finally the aortic valve (leading to the aorta). This sequence reflects the path of blood from the body, to the lungs, and back to the body.

Question 3

How many leads are recorded when recording an ECG?&#10;A) 10&#10;B) 4&#10;C) 12&#10;D) 6

Accepted Answer

An ECG typically records 12 leads, which include 6 limb leads and 6 precordial (chest) leads, providing comprehensive electrical activity of the heart from different angles.

Question 4

Which of the following blood vessels contains deoxygenated blood?&#10;A) Aorta&#10;B) Pulmonary veins&#10;C) Pulmonary artery&#10;D) Carotid artery

Accepted Answer

The pulmonary artery is the only vessel among the options listed that carries deoxygenated blood from the heart to the lungs for oxygenation.

Question 5

Alan is admitted to the hospital with a very low level of haemoglobin in his blood.
-What would be the best blood product to treat his anaemia?

A) Packed Red Blood Cells
B) Platelets
C) Fresh frozen plasma
D) Albumin

Accepted Answer

Packed Red Blood Cells (PRBCs) are the most appropriate choice for treating anemia because they directly increase the hemoglobin level and oxygen-carrying capacity of the blood.

Question 6

Alan is admitted to the hospital with a very low level of haemoglobin in his blood.&#10;-How would his anaemia affect him?&#10;A) Tiredness&#10;B) Breathlessness&#10;C) Dizziness&#10;D) All of these

Accepted Answer

Anaemia, characterized by a low level of haemoglobin, can lead to symptoms such as tiredness, breathlessness, and dizziness due to the reduced capacity of the blood to carry oxygen to the body's tissues.

Question 7

Elisha is intensive care for the treatment of heart failure.&#10;-Would her Starling's curve be ______?&#10;A) Normal&#10;B) Flattened&#10;C) Raised&#10;D) Unchanged

Accepted Answer

Starling's curve describes the relationship between ventricular filling (end-diastolic volume) and stroke volume. In heart failure, the curve is flattened because the heart's ability to pump blood efficiently is compromised, leading to a diminished increase in stroke volume with increased filling.

Question 8

Elisha is intensive care for the treatment of heart failure.
-What are the dangers of giving too much fluid to someone with heart failure?

A) Overload causing reduced cardiac output
B) Increase in cardiac output
C) Increased sweating
D) Increased conscious level

Accepted Answer

In patients with heart failure, administering too much fluid can lead to fluid overload. This condition exacerbates the heart's inability to pump efficiently, further reducing cardiac output and worsening heart failure symptoms.
