d. Arthritis
e. Chronic obstructive pulmonary diseas
The Correct Answer and Explanation is:
Sure! Here are the correct answers and detailed explanations for both questions:
Question 1:
In a human arm, the phalanges are to the humerus:
Correct Answer: a. distal
Explanation:
In anatomical terminology, “distal” and “proximal” are directional terms used to describe the position of one structure relative to another, particularly along the limbs.
When referencing the limbs (arms or legs), “distal” refers to a part that is further from the point of attachment to the trunk, while “proximal” means closer to that point of attachment.
Since the phalanges (fingers) are farther away from the shoulder joint (where the arm is attached to the trunk) than the humerus, the phalanges are considered distal to the humerus.
To clarify the other options:
- b. Proximal – Incorrect, because the phalanges are farther, not closer, to the shoulder than the humerus.
- c. Medial – Refers to a structure closer to the midline of the body; not relevant here.
- d. Lateral – Refers to a structure farther from the midline; again, not the best descriptor in this context.
- e. Superior – Means higher or above; typically used for vertical comparisons, not limb orientation.
Question 2:
Which is an example of an acute illness?
Correct Answer: c. Influenza
Explanation:
An acute illness refers to a disease or condition that has a rapid onset, typically a short duration, and usually resolves either on its own or with medical treatment. The symptoms tend to be severe but brief.
Influenza (flu) is a classic example of an acute illness:
- It begins suddenly, often with fever, chills, muscle aches, fatigue, and respiratory symptoms.
- It typically resolves within a few days to two weeks.
- It may require short-term treatment with antiviral drugs and supportive care.
- Recovery is expected, although complications (like pneumonia) can occur in vulnerable populations.
Let’s briefly compare with the incorrect options:
- a. Type 1 diabetes mellitus – A chronic illness that persists for life and requires continuous insulin therapy.
- b. Multiple sclerosis – A long-term chronic and often progressive neurological disorder.
- d. Arthritis – While some types can flare up suddenly, most forms (like osteoarthritis or rheumatoid arthritis) are chronic and long-lasting.
- e. Chronic obstructive pulmonary disease (COPD) – As the name implies, it is a chronic illness affecting the lungs over time.
Thus, influenza stands out as a textbook example of an acute illness due to its sudden onset, short duration, and potential for complete recovery.
