Care II (2026) Q&A
1. Which layer of the skin is responsible for providing structural support, containing blood
vessels, nerve endings, and hair follicles?
A) Epidermis
B) Dermis
C) Subcutaneous tissue
D) Stratum corneum
Correct Answer: Dermis
Rationale: The dermis is the middle layer of the skin and contains blood vessels, nerve
endings, hair follicles, and connective tissue that provide structural support. The epidermis
is the outermost layer, the subcutaneous tissue is the deepest layer, and the stratum
corneum is the outermost sublayer of the epidermis.
2. A patient presents with a flat, nonpalpable, circumscribed lesion less than 1 cm in
diameter, such as a freckle. Which term best describes this finding?
A) Papule
B) Macule
C) Nodule
D) Vesicle
Correct Answer: Macule
,Rationale: A macule is a flat, nonpalpable lesion less than 1 cm in diameter, such as a
freckle or petechia. A papule is a palpable solid elevation, a nodule is a deeper and firmer
elevated mass, and a vesicle is a fluid-filled elevation.
3. Which primary skin lesion is described as a palpable, solid elevation less than 1 cm in
diameter, such as an elevated nevus?
A) Macule
B) Papule
C) Pustule
D) Bulla
Correct Answer: Papule
Rationale: A papule is a palpable, solid elevation of the skin less than 1 cm in diameter,
such as an elevated nevus. A macule is flat and nonpalpable, a pustule contains pus, and a
bulla is a large fluid-filled blister.
4. A patient has a clear fluid-filled blister measuring 12 mm in diameter. Which term most
accurately describes this lesion?
A) Vesicle
B) Bulla
C) Pustule
D) Wheal
Correct Answer: Bulla
Rationale: A bulla is a clear fluid-filled blister greater than 10 mm in diameter, often
caused by burns, bites, or contact dermatitis. A vesicle is a smaller fluid-filled lesion, a
pustule contains pus, and a wheal is an irregularly shaped elevated area.
, 5. Which term describes an irregularly shaped, elevated skin lesion that is often associated
with hives or mosquito bites?
A) Nodule
B) Tumor
C) Wheal
D) Ulcer
Correct Answer: Wheal
Rationale: A wheal is an irregularly shaped, elevated area of skin edema, commonly seen
with hives or mosquito bites. A nodule is a deeper solid mass, a tumor is a solid mass deep
in subcutaneous tissue, and an ulcer is a deep loss of skin.
6. A patient presents with intense itching that is worse at night, and small 1–2 mm red
papules are noted in the webs of the fingers. Which diagnosis is most likely?
A) Pediculosis
B) Scabies
C) Impetigo
D) Tinea corporis
Correct Answer: Scabies
Rationale: Scabies is a highly contagious mite infestation characterized by intense itching
that is worse at night, with small red papules and burrows often located in the webs of
fingers, wrists, and axillary folds. Pediculosis causes itching but typically presents with nits
on hair shafts, impetigo presents with honey-crusted lesions, and tinea corporis presents
with annular scaly plaques.
