Choice A rationale: While ‘A’ is a vowel, it is not the most commonly used vowel when combining word parts in medical terminology.

Choice B rationale: ‘E’ is also a vowel, but it is not the most commonly used vowel when combining word parts in medical terminology.

Choice C rationale: ‘I’ is occasionally used as a combining vowel in medical terminology, but it is not the most commonly used.

Choice D rationale: ‘O’ is the most commonly used vowel when combining word parts in medical terminology. It helps with pronunciation and is placed to connect two word roots or to connect a word root and a suffix.

Choice E rationale: ‘U’ is a vowel, but it is not the most commonly used vowel when combining word parts in medical terminology

Choice A rationale:

The client's respirations are faster and deeper than normal due to expelling too much carbon dioxide. This condition is known as hyperventilation. Hyperventilation can occur due to various reasons such as anxiety, pain, fever, or metabolic acidosis. When the body expels excessive carbon dioxide, it leads to respiratory alkalosis, resulting in faster and deeper breathing to compensate for the decrease in carbon dioxide levels in the blood.

Choice B rationale:

This option is incorrect. Hypoxemia, or low blood oxygen levels, typically leads to rapid, shallow breathing (tachypnea) rather than deep and fast respirations.

Choice C rationale:

This option is incorrect. Inflammation of the phrenic nerve does not directly affect the depth and rate of respirations. Phrenic nerve inflammation is more likely to cause pain during breathing or hiccups.

Choice D rationale:

This option is incorrect. Using intercostal muscles to breathe is a normal physiological process, especially during deep or labored breathing. However, it does not explain the specific situation described in the question, where the respirations are faster and deeper than normal.
