35
Q

What is the most effective treatment for cysts?

  1. Oral antibiotics
  2. Hibiclens scrub
  3. Incision and drainage
  4. Topical steroids
A

3. Incision and drainage

Cysts are self-contained pockets of bacteria and WBCs. The best treatment is to open the self-contained cyst and allow drainage to occur. Oral antibiotics or topical antibiotics may be prescribed after the I&D (incision and drainage).

36
Q

A patient has been told that he should have Mohs surgery on a cancerous lesion. The patient asks what Mohs surgery is. The nurse practitioner explains that:

  1. The cancerous lesion is removed, as well as the surrounding lymph nodes.
  2. The surface area of the lesion is excised and the underlying area is cauterized to prevent further growth.
  3. The lesion is excised and examined under a microscope to determine if wound edges are free from cancer or if further excision is required.
  4. A wide excision is performed to avoid having to do further surgery.
A

39
Q

A patient presents to the clinic with complaints of pruritus of the left hand. The NP observes several erythematous papules and linear burrows in the interdigital web spaces of the left hand. The nurse practitioner diagnoses the patient with which of the following?

  1. Tinea corporis
  2. Scabies
  3. Lice
  4. Onychomycosis
A

2. Scabies

Linear burrows are a classic sign of scabies. Scabies will often present in the interdigital areas of the hands, but are not limited to this area, and may appear anywhere on the body. The NP should examine all close family contacts because scabies is often found in crowded living conditions.

40
Q

A 45-year-old male patient presents to the clinic concerned about a mole on his upper back area.

  4. Any person of northern European descent
A

2. Caucasian males over the age of 50

Men over the age of 50 have the highest incidence of melanoma.

44
Q

An important prognostic factor for a patient diagnosed with melanoma is which of the following?

  1. The number of blistering sunburns the patient has experienced over his lifetime.
  2. A family history of melanoma.
  3. The thickness of the lesion and if ulceration is present at the time of diagnosis.
  4. The diameter of the lesion.
A

3. The thickness of the lesion and if ulceration is present at the time of diagnosis.

Characteristics such as thickening or ulceration at the time of diagnosis is the most important factor in the patient’s prognosis. The other answers are indicative of the patient’s risk for melanoma.

45
Q

A 35-year-old female patient presents to the nurse practitioner for a routine physical exam. During the skin assessment, the patient comments about a lesion that is present on the dorsal portion of her lower left leg. Which of the following statements made by the patient is the most concerning?

  1. “I think this mole is a different color than the other moles I have.”
  2. “This mole seems like it grew overnight.”
  3. “This mole is larger than the other moles I have on my body.”
  4. “Sometimes this mole is itchy.”
A

2. “This mole seems like it grew overnight.”

Any mole that has grown quickly must be immediately evaluated and biopsied because this is a typical characteristic of a malignant melanoma.

46
Q

A patient’s chances of developing a melanoma is closely related to which of the following?

  1. The number of melanocytes present in the dermis
  2. The number of blistering sunburns the patient has experienced in his or her lifetime
  3. The amount of time he/she has spent outdoors
  4. Chronic exposure to known carcinogens such as free radicals
A

2. The number of blistering sunburns the patient has experienced in his or her lifetime
