Client records.

This is because client records contain objective and measurable data on the wound healing process, such as size, depth, drainage, infection, and pain.

Client records are also reliable and valid sources of data that can be easily accessed and compared.

Choice B is wrong because client interviews are subjective and may not reflect the actual effectiveness of the wound dressing.

Client interviews may also be influenced by factors such as mood, recall, and rapport.

Choice C is wrong because client surveys are also subjective and may not capture the relevant aspects of wound healing.

Client surveys may also have low response rates or biased responses.

Choice D is wrong because client observations are not enough to evaluate the effectiveness of a wound dressing.

Client observations may be affected by personal preferences, expectations, or beliefs.

Normal ranges for wound healing depend on various factors such as the type, location, and severity of the wound, the patient’s age, health status, and nutrition, and the type of dressing used.

However, some general guidelines are:.

• Acute wounds (such as surgical incisions) should heal within 2 to 4 weeks.

• Chronic wounds (such as pressure ulcers) may take longer than 6 weeks to heal.

• Wounds should show signs of improvement such as reduced size, decreased drainage, decreased inflammation, and increased granulation tissue within 2 weeks of treatment.
