Answer to Question 1

Correct Answer: 2
The Tzanck smear is used to diagnose herpes infections. Patch testing is used to assess allergens. The Wood's lamp test is used to assess for tinea infections. The potassium chloride test is used to diagnose interstitial cystitis.

Answer to Question 2

Correct Answer: 1
The nurse is noting liver spots or small areas of hyperpigmentation over the patient's hands. This is due to hyperplasia of melanocytes, especially in sun-exposed areas of the epidermis. Alterations in vitamin D production, reduced blood perfusion, and changes in adipose tissue are not associated with excessive pigmentation.
