When the patient complains of worsening due to increased swelling at the wound site on his leg, the nurse explains that the swelling indicates:
He has lain in one position for such a long time that swelling has occurred.
An infection is in progress at the wound site.
There is probably a deeper injury than what appears on the surface.
Vessels have dilated and allowed plasma to leak into the wound site.
The Correct Answer is D
Choice A rationale
Prolonged immobility can indeed cause swelling due to fluid accumulation; however, it typically does not lead to sudden worsening or significant swelling at a specific wound site. It is more associated with generalized edema, particularly in dependent areas of the body.
Choice B rationale
While infections can cause swelling, they are also accompanied by other signs such as redness, warmth, pain, and possibly fever. Swelling alone, without these other symptoms, is less indicative of an infection.
Choice C rationale
A deeper injury might cause swelling, but this would have been identified during the initial assessment. Swelling that occurs later in the healing process is less likely to be from a deeper, previously unnoticed injury.
Choice D rationale
Swelling at a wound site is often due to inflammation, where blood vessels dilate and become more permeable, allowing plasma to leak into the tissue. This is a normal part of the healing process as the body brings in necessary cells and substances to promote recovery.

Correct Answer is C
Explanation
Choice A:
While marijuana use can have various health effects, it is not typically associated with a reduction in functional hemoglobin.
Choice B:
A diet high in fats can lead to various health problems, such as heart disease and obesity, but it is not directly linked to a reduction in functional hemoglobin.
Choice C:
Smoking cigarettes can indeed lead to a reduction in functional hemoglobin. Smokers have higher blood hemoglobin concentrations than non-smokers. This is because smoking causes the body to increase red blood cell production to compensate for lower oxygen supply.
Choice D:
While excessive alcohol consumption can have numerous negative health effects, it is not typically associated with a reduction in functional hemoglobin.
Correct Answer is ["A","C","E"]
Explanation
Choice A rationale
Adequate fibroblast function is crucial for wound healing as fibroblasts play a key role in the formation of new connective tissue and collagen, which are essential for the repair process.
Choice B rationale
Intrinsic factor is not directly related to wound healing; it is a glycoprotein produced by the stomach lining that is necessary for the absorption of vitamin B12.
Choice C rationale
The synthesis of collagen is vital for wound healing because collagen is the main structural protein in the skin and other connective tissues, providing strength and support to the wound site.
Choice D rationale
While hemoglobin is essential for transporting oxygen in the blood, it is not a factor in the local wound healing process.
Choice E rationale
Adequate phagocytosis is important in wound healing as it involves the ingestion and removal of pathogens and debris by phagocytes, which is a critical step in preventing infection and allowing the healing process to proceed.
