1. A microscopic examination of the sample taken from
... [Show More] a skin lesion indicates
hyphae. What type of infection might this indicate? (Fungal)
Under microscopic exam, hyphae are long, thin and branching and indicate dermatophytic
infections. Hyphae are typical in tinea pedis, tinea cruris, and tinea corporis.
2. A child with a sandpaper-textured rash probably has: (Strep infection)
Streptococcal infections can present as a sandpaper-textured rash that initially is felt on the
trunk. Rubeola, measles, produces a blanching erythematous “brick-red” maculopapular
rash that begins on the back of the neck and spreads around the trunk and then
extremities. Varicella infection produces the classic crops of eruptions on the trunk that
spread to the face. The rash is maculopapular initially and then crusts. Roseola produces a
generalized maculopapular rash preceded by 3 days of high fever.
3. A 40-year-old female patient presents to the clinic with multiple, painful
reddened nodules on the anterior surface of both legs. She is concerned. These
are probably associated with her history of: (ulcerative colitis)
These nodules describe erythema nodosum. These are most common in women aged 15-40
years old. They are typically found in pretibial locations and can be associated with
infectious agents, drugs, or systemic inflammatory disease like ulcerative colitis. They
probably occur as a result of a delayed hypersensitivity reaction to antigens. It is not
unusual to find polyarthralgia, fever, and/or malaise that precede or accompany the skin
nodules.
4. A patient is diagnosed with tinea pedis. A microscopic examination of the
sample taken from the infected area would likely demonstrate: (hyphae)
Under microscopic exam, hyphae are long, thin and branching, and indicate dermatophytic
infections. Hyphae are typical in tinea pedis, tinea cruris, and tinea corporis. Yeasts are
usually seen in candidal infections. Cocci and rods are specific to bacterial infections.
5. When can a child with chickenpox return to daycare? (After all lesions have
crusted)
Chickenpox is highly contagious and can be spread via respiratory secretions from an
infected person or by direct contact from the vesicle fluid from lesions on the skin or mucus
membranes. The usual incubation period is about 2 weeks but can be as long as 21 days or
as short as 10 days. The greatest period of infectivity is 48 hours prior to the onset of the
rash and until all the skin lesions have crusted over. [Show Less]
