A nurse explains to a client with hypertension that diastolic pressure is a measurement of what?

The amount of force blood places on the arterial walls while both the atria and the ventricles relax.

The amount of force blood places on the arterial walls while the ventricles contract.

The amount of force blood places on the arterial walls while both the atria and the ventricles contract.

The amount of force blood places on the arterial walls while the ventricles relax.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

Airborne transmission typically involves smaller particles that can remain suspended in the air for longer periods. Sneezing, in this case, usually produces smaller droplets that can travel farther distances and potentially infect individuals beyond a few feet away.

Choice B rationale:

Direct contact transmission occurs when there is physical contact between an infected person and a susceptible individual. In this scenario, the infected drainage from the client's wound directly touches the nurse's cut, leading to infection. This type of transmission is characterized by the transfer of microorganisms through physical touch or contact with the skin.

Choice C rationale:

Droplet contact transmission involves larger respiratory droplets that are expelled when a person coughs, sneezes, or talks. These droplets typically do not travel far and can only infect people who are in close proximity. In this case, the scenario describes a client coughing on their hand and another person becoming infected by touching the contaminated door handle. This aligns with direct contact transmission rather than droplet contact transmission.

Choice D rationale:

Indirect contact transmission refers to the transfer of an infectious agent from a contaminated surface or object to a susceptible person. However, the scenario provided does not involve the nurse coming into contact with a contaminated surface but rather with the infected drainage directly. Therefore, this scenario is best categorized under direct contact transmission.

Correct Answer is A

Explanation

Choice A rationale:

Diastolic pressure represents the pressure in the arteries when the heart is at rest between contractions. It specifically measures the force of blood against the arterial walls when both the atria and ventricles are relaxed, allowing the heart to fill with blood. Diastolic pressure is the bottom number in a blood pressure reading (e.g., 120/80 mmHg), indicating the pressure in the arteries during the heart's resting phase. Elevated diastolic pressure is an important indicator of increased risk for cardiovascular diseases, such as hypertension.

Choice B rationale:

This statement describes systolic blood pressure, which measures the pressure in the arteries when the heart's ventricles contract and pump blood into the circulation. Systolic pressure is the top number in a blood pressure reading (e.g., 120/80 mmHg) and represents the highest pressure reached in the arteries during a cardiac cycle.

Choice C rationale:

This description is not accurate for either diastolic or systolic pressure. Both atria and ventricles do not contract simultaneously; they follow a specific sequence to ensure effective pumping of blood through the heart.

Choice D rationale:

This statement is incorrect as it does not align with the definitions of diastolic or systolic blood pressure. Diastolic pressure specifically measures the pressure in the arteries during the heart's resting phase, not when the ventricles relax. .

A. gastro. B. nephro. C. oto. D. uro.

Correct Answer is B

Explanation

Choice A rationale:

Gastro- refers to the stomach. This prefix is commonly used in medical terminology to indicate conditions related to the stomach or the gastrointestinal system.

Choice B rationale:

Nephro- is the correct medical term for kidney. The prefix nephro- is used to indicate conditions related to the kidney, such as nephritis (inflammation of the kidney)

Choice C rationale:

Oto- refers to the ear. This prefix is commonly used in medical terms related to the ear and hearing, such as otitis (inflammation of the ear)

Choice D rationale:

Uro- refers to the urinary tract. While it is related to the kidneys in the context of the urinary system, it is not the specific term for kidney. Uro- is used in words like urology (the branch of medicine that deals with the urinary system and male reproductive system)
