Question 1

What causes a loud, high-pitched sound during breathing?

Accepted Answer

Stridor

Answer

Stridor is a harsh, high-pitched, musical sound produced during breathing, typically heard on inspiration. It is caused by turbulent airflow through a partially obstructed upper airway, such as the larynx or trachea. Stridor is a significant clinical sign indicating potential airway compromise and requires immediate assessment and intervention.

Question 2

What is breathing difficulty?

Accepted Answer

An act that prevents needed gas exchange

Answer

Breathing difficulty, or dyspnea, is the subjective sensation of uncomfortable or labored breathing. Physiologically, it often arises when the body's demand for gas exchange—taking in sufficient oxygen and expelling carbon dioxide—is not adequately met. This can be caused by various underlying conditions that impair the efficiency of the respiratory system, thereby preventing needed gas exchange.

Question 3

What does the air lack in terms of breathing?

Accepted Answer

Respiratory arrest

Answer

Respiratory arrest refers to the complete cessation of breathing. When breathing stops, the body can no longer take in oxygen or remove carbon dioxide, leading to a rapid and critical lack of oxygen in the blood and tissues. This condition is life-threatening and, if not promptly reversed, will quickly lead to cardiac arrest and death.

Question 4

Which tissue is not impacted by leukemia?

Accepted Answer

Kidney

Answer

Leukemia is a cancer of the blood-forming tissues, primarily originating in the bone marrow. While it can spread and affect organs rich in lymphatic tissue, such as the liver, spleen, and lymph nodes, the kidney is not a primary site of leukemia cell proliferation. Although leukemia can indirectly cause kidney damage through complications like tumor lysis syndrome, the kidney itself is not directly impacted as a tissue where leukemia typically originates or extensively infiltrates.

Question 5

What are SIDS?

Accepted Answer

Sudden infant death syndrome

Answer

SIDS stands for Sudden Infant Death Syndrome. It refers to the sudden, unexpected, and unexplained death of an infant younger than one year of age, typically occurring during sleep. SIDS remains a diagnosis of exclusion after a thorough investigation, including an autopsy, examination of the death scene, and review of the clinical history.
