Choice A reason:

Family history of cardiac disease is a non-modifiable risk factor. This means it cannot be changed or controlled through lifestyle or behavioral modifications. A family history of heart disease increases an individual’s risk, but it is not something that can be altered.

Choice B reason:

Increasing age is another non-modifiable risk factor. As people age, their risk for cardiovascular disease naturally increases. This is due to the cumulative effects of aging on the cardiovascular system, which cannot be changed.

Choice C reason:

The diagnosis of diabetes mellitus is a complex risk factor. While the presence of diabetes itself is not modifiable, the management of diabetes through lifestyle changes, medication, and diet can significantly reduce cardiovascular risk. However, the condition itself remains a non-modifiable risk factor.

Choice D reason:

Cigarette smoking is a modifiable risk factor. This means that individuals can reduce their risk of cardiovascular disease by quitting smoking. Smoking cessation has been shown to significantly lower the risk of heart disease and improve overall cardiovascular health.

Choice A reason: A High Concentration of Carbon Monoxide Can Cause Death

This statement is correct. Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be deadly at high concentrations. It binds to hemoglobin in the blood more effectively than oxygen, leading to hypoxia (lack of oxygen) in body tissues. High levels of CO can cause severe symptoms such as confusion, loss of consciousness, and death if not treated promptly.

Choice B reason: I Should Purchase a Carbon Monoxide Detector for My Home

This statement is also correct. Installing a carbon monoxide detector in the home is a crucial safety measure. These detectors can alert individuals to the presence of CO, allowing them to take action before the gas reaches dangerous levels. It is recommended to place detectors near sleeping areas and to test them regularly to ensure they are functioning properly.

Choice C reason: Breathing in Carbon Monoxide Can Cause Headaches and Nausea

This statement is accurate. Early symptoms of carbon monoxide poisoning include headaches, dizziness, nausea, and fatigue. These symptoms occur because CO interferes with the body’s ability to transport and use oxygen, leading to hypoxia. If exposure continues, symptoms can worsen and lead to more severe health issues.

Choice D reason: I Can Detect the Presence of Carbon Monoxide by a Metallic Odor

This statement indicates a need for further instruction. Carbon monoxide is odorless, which means it cannot be detected by smell. This is why CO is often referred to as a “silent killer.” Relying on the ability to smell CO is dangerous and ineffective. The only reliable way to detect CO is through the use of a carbon monoxide detector.
