Which term is used to identify an elevated, erythematous lesion that contains purulent exudate (pus).
Macule
Pustule
Papule
Nodule
The Correct Answer is B
A. Macule is incorrect because a macule is a flat, non-palpable lesion that represents a change in skin color. Examples include freckles or flat rashes. Macules do not contain fluid or pus, nor are they raised.
B. Pustule is correct because a pustule is a small, elevated, erythematous lesion that contains purulent material (pus). Pustules are commonly seen in infections such as acne, impetigo, or folliculitis. The presence of pus indicates an inflammatory response to infection, trauma, or obstruction of a gland.
C. Papule is incorrect because a papule is a solid, raised lesion without fluid. Papules can be caused by a variety of dermatologic conditions such as warts or early stages of acne, but they do not contain pus.
D. Nodule is incorrect because a nodule is a larger, solid, firm lesion that extends deeper into the dermis or subcutaneous tissue. Nodules can result from cysts, tumors, or chronic inflammatory processes, but they are not typically associated with purulent exudate.

Correct Answer is A
Explanation
A. Hypercapnia is correct because it refers to an abnormally high level of carbon dioxide (CO₂) in the blood, often resulting from hypoventilation, respiratory diseases (like COPD), or impaired gas exchange. Elevated CO₂ can lead to respiratory acidosis, causing confusion, headache, lethargy, and, in severe cases, respiratory failure.
B. Hypocapnia is incorrect because this term refers to abnormally low CO₂ levels in the blood, which can occur due to hyperventilation. Hypocapnia can lead to respiratory alkalosis with symptoms such as dizziness, tingling, and muscle cramps.
C. Hypoxemia is incorrect because hypoxemia refers to low oxygen levels in the blood, not elevated carbon dioxide. It may result from lung disease, high altitude, or impaired oxygen transport.
D. Hyperpnea is incorrect because hyperpnea refers to increased depth and rate of breathing, usually as a compensatory mechanism for increased CO₂ or metabolic demands, rather than the presence of elevated CO₂ itself.
Correct Answer is B
Explanation
A. High urine pH is incorrect because while urine pH can influence bacterial growth, it is not the primary factor contributing to recurrent UTIs in older men. Other conditions, such as structural or functional urinary obstruction, are more significant.
B. Urine retention due to an enlarged prostate is correct because benign prostatic hyperplasia (BPH) is common in older men and can cause partial obstruction of urine flow. This leads to urine stasis, which creates an environment conducive to bacterial growth, significantly increasing the risk of recurrent UTIs. Urine that is not fully expelled allows bacteria to multiply and ascend the urinary tract.
C. Use of cotton underwear is incorrect because wearing breathable underwear may help reduce irritation or moisture-related infections, but it is not a major contributor to UTIs in older men. Recurrent UTIs are more closely linked to urinary retention and obstruction.
D. Increased fluid intake is incorrect because higher fluid intake actually helps prevent UTIs by diluting urine and promoting regular bladder emptying. It reduces bacterial concentration and decreases the risk of infection, rather than causing recurrent infections.
