The nurse warns the patient that one of the patient’s habits has caused the reduction of functional hemoglobin, which limits the hemoglobin’s oxygen-carrying ability. To improve this situation, the nurse suggests that the patient quit:
Using marijuana.
Eating excessive fats.
Smoking cigarettes.
Drinking
The Correct Answer is C
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.
Correct Answer is B
Explanation
Choice A rationale
Stage 1 wounds are characterized by non-blanchable redness of intact skin. The presence of partial-thickness skin loss indicates that the wound has progressed beyond stage 1, making this choice incorrect.
Choice B rationale
Stage 2 wounds involve partial-thickness loss of dermis presenting as a shallow open ulcer with a red-pink wound bed, without slough. This description matches the nurse’s assessment of the patient’s wound, confirming that it is indeed a stage 2 wound.
Choice C rationale
Stage 3 wounds exhibit full-thickness tissue loss. Subcutaneous fat may be visible, but bone, tendon, or muscle are not exposed. The patient’s wound, with partial-thickness skin loss and no mention of exposed subcutaneous structures, does not fit the criteria for stage 3.
Choice D rationale
Stage 4 wounds involve full-thickness tissue loss with exposed bone, tendon, or muscle. Slough or eschar may be present on some parts of the wound bed. The patient’s wound does not have these characteristics, ruling out stage 4.
