The hypoxic drive is stimulated by:
- A.
Low PaO2
- B.
High PaCO2
- C.
Low PACO2
- D.
High PaO2
Correct Answer
A. Low PaO2Explanation
The hypoxic drive is a respiratory control mechanism that is stimulated by low levels of oxygen in the blood (low PaO2). When the oxygen levels in the blood are low, the hypoxic drive signals the body to increase the respiratory rate and depth in order to bring in more oxygen. This response helps to compensate for the low oxygen levels and maintain adequate oxygenation throughout the body. High levels of PaCO2, low levels of PACO2, and high levels of PaO2 do not directly stimulate the hypoxic drive.Rate this question:

- C.
At the glottic opening
- D.
At the junction of the hard and soft palates
Correct Answer
A. In the valleculaExplanation
The tip of a curved laryngoscope blade is placed correctly in the vallecula. The vallecula is a small groove located between the base of the tongue and the epiglottis. Placing the laryngoscope blade in the vallecula helps to lift and expose the epiglottis, allowing for a clear view of the glottic opening. This position is crucial for successful intubation as it provides the best visualization of the vocal cords and facilitates the passage of the endotracheal tube into the trachea.Rate this question:

A decrease in cell size resulting from a decreased workload is called
- A.
Hyperplasia
- B.
Mitosis
- C.
Atrophy
- D.
Dysplasia
Correct Answer
C. AtrophyExplanation
Atrophy refers to a decrease in cell size, which occurs as a result of decreased workload or disuse. This can happen due to various reasons such as decreased physical activity, immobilization, or lack of nerve stimulation. When cells undergo atrophy, they shrink in size and their function is impaired. This process is different from hyperplasia, which involves an increase in the number of cells, and mitosis, which is the process of cell division. Dysplasia, on the other hand, refers to abnormal cell growth and is not related to a decrease in cell size.Rate this question:

Aerobic exercise gradually causes _______ of the myocardium
- A.
Dilation
- B.
Atrophy
- C.
Hypertrophy
- D.
Hyperplasia
Correct Answer
C. HypertrophyExplanation
Aerobic exercise gradually causes hypertrophy of the myocardium. This means that the myocardium, which is the muscular tissue of the heart, undergoes an increase in size and mass. This is a beneficial adaptation to aerobic exercise as it allows the heart to pump more efficiently and effectively, delivering oxygen and nutrients to the body's tissues. This increase in myocardial size is a result of the heart working harder during aerobic exercise, causing the muscle cells to grow and strengthen.Rate this question:

The most common cause of cellular injury is oxygen deficiency, or
- A.
Ischemia
- B.
Hypoxia
- C.
Infarction
- D.
Inflammation
Correct Answer
B. HypoxiaExplanation
Hypoxia refers to a condition where there is a decrease in the amount of oxygen reaching the body's tissues. This can occur due to various reasons such as reduced blood flow, inadequate oxygenation of the blood, or impaired oxygen-carrying capacity of the blood. Oxygen deficiency leads to cellular injury as cells require oxygen to carry out their normal functions, including energy production. Without sufficient oxygen, cells are unable to generate energy, leading to cellular dysfunction and ultimately cell death. Therefore, hypoxia is the most common cause of cellular injury.Rate this question:
