Question 1

What is a normal resting heart rate for adults?

Accepted Answer

60-100 bpm

Answer

A normal resting heart rate for adults typically falls between 60 and 100 beats per minute (bpm). This range indicates that the heart is efficiently pumping blood throughout the body while the individual is at rest. A heart rate consistently outside this range, either too low (bradycardia) or too high (tachycardia), can sometimes indicate underlying health issues and may warrant medical attention.

Question 2

Which test assesses cardiac rhythm?

Accepted Answer

ECG

Answer

An Electrocardiogram (ECG or EKG) is a non-invasive test that records the electrical activity of the heart. It detects and graphs the heart's electrical impulses, allowing healthcare professionals to assess heart rate, rhythm, and identify various cardiac conditions. This makes it the primary tool for evaluating cardiac rhythm.

Question 3

What is a sign of left-sided heart failure?

Accepted Answer

Shortness of breath

Answer

Left-sided heart failure occurs when the left ventricle cannot pump enough blood to the body, leading to blood backing up into the lungs. This pulmonary congestion causes fluid to accumulate in the lung tissues and air sacs, resulting in symptoms like dyspnea (shortness of breath), especially with exertion or when lying flat. Other options like edema and weight gain are more characteristic of right-sided heart failure.

Question 4

Which lung sound indicates fluid?

Accepted Answer

Crackles

Answer

Crackles, also known as rales, are short, popping, or crackling sounds heard during auscultation of the lungs. They typically indicate the presence of fluid in the small airways or alveoli, often associated with conditions like pneumonia, heart failure, or pulmonary edema. The sound is produced when air passes through fluid-filled airways, causing them to open and close.

Question 5

Which intervention helps COPD patients breathe?

Accepted Answer

Pursed-lip breathing

Answer

Pursed-lip breathing is a technique that helps patients with Chronic Obstructive Pulmonary Disease (COPD) manage their shortness of breath. By exhaling slowly through pursed lips, it creates back-pressure in the airways, which helps to keep them open longer and prevents air trapping. This allows for more complete exhalation, improves oxygenation, and reduces the work of breathing.
