Chapter 25 Questions
Question 1 of 5
A patient asks the nurse why a potassium hydroxide test needs to be done. The nurse's response is based upon the knowledge that which of the following is the purpose of this test?
Correct Answer: C
Rationale: A potassium hydroxide test is done to examine hair, nails, or scales for superficial fungal infection. Scraping exudate from a lesion for examination is used with mineral oil slides. A Tzanck test is used when fluid is obtained from vesicles for assessment.
Question 2 of 5
Which assessment information documented in a patient's chart indicates that the nurse may need to continue to monitor the skin condition of an 82-year-old patient admitted with bacterial pneumonia?
Correct Answer: D
Rationale: Because the patient will be receiving antibiotics, the nurse should monitor the patient for the presence of an allergic rash. The assessment data in the other responses would be normal for an elderly patient.
Question 3 of 5
The nurse is admitting an older-adult patient to an assisted-living facility and notes abnormalities on the skin. Which of the following abnormalities is the priority to discuss immediately with the health care provider?
Correct Answer: D
Rationale: Petechiae are caused by pinpoint hemorrhages and are associated with inflammation, marked dilation, blood vessel trauma, and blood dyscrasias that result in bleeding tendencies (e.g., thrombocytopenia). The nurse should contact the patient's health care provider about this finding for further diagnostic follow-up. The other skin changes are associated with aging. Although the other changes also will require ongoing monitoring or intervention by the nurse, they do not indicate a need for urgent action.
Question 4 of 5
The nurse is conducting an assessment of the patient's skin and observes a ring of small, raised, discrete lesions filled with serous fluid on the patient's right temple. Which of the following descriptions would the nurse use when documenting the lesions?
Correct Answer: A
Rationale: The description of the lesions indicates that they are grouped. Confluent lesions merge into one another, zosteriform lesions follow a dermatome, and generalized lesions are widespread across the body.
Question 5 of 5
The nurse is caring for a patient in the dermatology clinic who is scheduled for removal of a 15-mm multicoloured and irregular mole from the upper back. Which of the following biopsies would the nurse teach to this patient?
Correct Answer: C
Rationale: An incisional biopsy would remove the entire mole and the tissue borders. The appearance of the mole indicates that it may be malignant: a shave biopsy would not remove the entire mole. The mole is too large to be removed with punch biopsy. Excisional biopsies are done for smaller lesions and where a good cosmetic effect is desired, such as on the face.
