The nurse instructs a patient on care required after a punch biopsy. Which patient statement indicates that teaching has been effective?

Correct Answer: B

Rationale: The correct answer is B because changing the bandage daily helps prevent infection and promotes wound healing. This statement also demonstrates understanding of proper post-biopsy care. Choice A is incorrect as showering is typically allowed after a punch biopsy. Choice C is incorrect as some blood on the dressing is normal post-biopsy. Choice D is incorrect as it takes time for the biopsy site to heal, and it's not uncommon for it to take longer than a few days.

Correct Answer: C

Rationale: Rationale: C: Zinc is essential for protein synthesis, aiding in wound healing, crucial for pressure ulcer recovery. A: Strengthening capillaries is more related to vitamin C. B: Immune function is supported by zinc, but not the primary reason for pressure ulcer treatment. D: Red blood cell formation mainly requires iron, not zinc.

Correct Answer: D

Rationale: The correct answer is D because all the choices listed (A, B, and C) are types of general receptors located in the skin. Meissner's corpuscles and Pacinian corpuscles are encapsulated receptors responsible for detecting touch and pressure, while free nerve endings are unencapsulated receptors that respond to pain, temperature, and pressure. Therefore, selecting "All of the above" encompasses all four types of general receptors present in the skin.

Correct Answer: B

Rationale: The correct answer is B: Diarrhea. Acyclovir is an antiviral medication that can commonly cause gastrointestinal side effects, such as diarrhea. This occurs due to its effect on the digestive system. The other choices, headache (A), nausea (C), and fatigue (D), are less commonly associated with acyclovir. Headache may occur but is not a common side effect. Nausea is less frequent than diarrhea. Fatigue is not a typical side effect of acyclovir. Therefore, the correct answer is B as diarrhea is a more common side effect of acyclovir compared to the other options.

Correct Answer: A

Rationale: The correct answer is A because psoriasis is less common among individuals with darker skin tones, such as African Americans. It is more prevalent in individuals with lighter skin tones. Psoriasis is also associated with genetic factors, so choice B, a Caucasian with family history, is at higher risk. Obesity (choice C) and arthritis (choice D) are risk factors for psoriasis due to their inflammatory nature, making choices C and D less likely to be at least at risk compared to choice A.
