Health Assisting Unit 1 Flashcard

Front

Imagine a scenario where a person is exposed to an environment with a high concentration of harmful particles and germs. Using your understanding of the respiratory system, explain how this system helps protect the person and what might happen if the system fails to filter these particles effectively.

Back

The respiratory system filters harmful particles and germs, preventing them from entering the body; if it fails, the person may become ill due to infection or respiratory issues.

Front

A patient is unable to filter dust and other particles from the air when breathing through their mouth. Using your understanding of the upper respiratory system, explain why this occurs and which structure is responsible for filtration.

Back

The oral cavity does not have a filtration system, unlike the nasal cavity.

Front

Using your understanding of the respiratory system, explain how the larynx functions as a boundary between the upper and lower respiratory tracts and discuss the significance of this division in terms of air flow and sound production.

Back

The larynx acts as a boundary, allowing air in and out of the lungs and enabling sound production, thus separating the upper and lower respiratory tracts.

Front

Given the functions of the trachea, bronchi, and alveoli, devise a scenario where a blockage occurs in one of these structures. Explain how this blockage would impact the process of gas exchange in the lungs and justify your reasoning.

Back

A blockage in the trachea would prevent air from reaching the bronchi and alveoli, severely limiting gas exchange.

Front

The upper and lower respiratory system divides at what structure?

Back

Larynx

Front

A new disease is discovered that primarily affects the air sacs in the lungs. Based on the respiratory roots, which root would most likely be used in naming this disease, and why?

Back

Pne/Pneum-; because it refers to air or lung

Front

Given the roots "phren-" and "laryng-", analyze how these roots help in understanding the medical terms "phrenic nerve" and "laryngitis." Explain the relationship between the root and the meaning of each term.

Back

"Phren-" refers to the diaphragm, so "phrenic nerve" is a nerve related to the diaphragm; "laryng-" refers to the voice box, so "laryngitis" is inflammation of the voice box.

Front

What does hypoxemia mean?

Back

Low oxygen in blood

Front

A patient reports feeling dizzy and nauseous, but the healthcare provider cannot observe any physical signs of illness. How would you classify these symptoms, and why?

Back

These are subjective symptoms because they are reported by the patient and cannot be directly observed.

Front

A patient states, "My head hurts." Is this an example of subjective or objective data, and why?

Back

Subjective, because it is based on the patient's personal experience and cannot be measured by others.
