Which medical terminology word part provides the general meaning of the word?
Combining vowel.
Word root.
Suffix.
Prefix.
The Correct Answer is B
Choice A rationale:
A combining vowel is a vowel (usually "o") that connects a word root to a suffix or another root. It aids in the pronunciation and flow of the word. For example, in the word "gastroenteritis," "o" is the combining vowel that connects the word root "gastr-" (stomach) to the suffix "-itis" (inflammation) Combining vowels do not provide the general meaning of the word.
Choice B rationale:
The word root provides the fundamental meaning of the word. It is the core of the medical term and gives the essential meaning. For example, in the word "cardiology," the word root "cardio-" refers to the heart. Understanding word roots is crucial in comprehending medical terminology.
Choice C rationale:
A suffix is an affix added at the end of a word to form a derivative, indicating a characteristic of a person or thing. For instance, in the word "dermatologist," the suffix "-ologist" indicates a person who studies or practices a particular kind of knowledge, in this case, dermatology (the study of the skin)
Choice D rationale:
A prefix is an affix added to the beginning of a word to modify its meaning. For example, in the term "preoperative," the prefix "pre-" means before, and it modifies the root word "operative," indicating something that occurs before an operation. Prefixes provide additional information about the word's context but do not give the general meaning of the word itself.

Correct Answer is D
Explanation
Choice A rationale:
Healthcare-associated infections (HAIs) do not necessarily occur due to compromised immunity. HAIs refer to infections that patients acquire while receiving treatment for medical or surgical conditions, and they can happen to individuals with varying levels of immunity.
Choice B rationale:
While infections during therapeutic procedures are a concern, not all healthcare-associated infections occur during such procedures. HAIs can happen in various healthcare settings and not limited to therapeutic procedures.
Choice C rationale:
Inhaling pathogens in a healthcare setting might lead to infections, but not all healthcare-associated infections happen due to inhalation. HAIs can occur through different modes of transmission.
Choice D rationale:
Healthcare-associated infections (HAIs) occur when a patient acquires an infection while receiving care in a healthcare setting, including hospitals. This can involve various sources, such as contaminated medical equipment, surgical procedures, or interactions with healthcare personnel.
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. .
