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 D
Explanation
Choice A rationale
Healing by second intention occurs when a wound is left open and allowed to close by granulation, epithelialization, and contraction. This method is used for wounds that are infected, have lost tissue, or where there is a delay in suturing. It is not applicable in this case as the wound is sutured and healing cleanly.
Choice B rationale
There is no recognized method of wound healing known as fourth intention. This option does not exist in medical terminology related to wound healing and is therefore not a correct choice.
Choice C rationale
Third intention, also known as delayed primary closure, is when a wound is initially left open due to contamination or infection and is not closed until it is clean. This is not the case here as the wound has been sutured closed from the beginning.
Choice D rationale
First intention, also known as primary intention, is when a clean wound is immediately closed with sutures, staples, or adhesive, leading to minimal scarring. This is the method described in the scenario, where the post-surgical wound is clean, dry, and the sutures are intact, indicating healing by first intention. This method is typically used for surgical incisions under sterile conditions.
Correct Answer is A
Explanation
Choice A rationale
Dakin’s solution is an antiseptic containing sodium hypochlorite, used in chemical debridement to clean wounds and remove dead tissue. It helps to reduce the bacterial load and prepares the wound bed for healing by removing non-viable tissue.
Choice B rationale
While Dakin’s solution aids in the overall healing process by cleaning the wound, it does not directly cause healing. Healing is a complex process involving tissue regeneration and repair, which Dakin’s solution supports indirectly.
Choice C rationale
Phagocytosis is a part of the immune response where cells engulf and digest pathogens and debris. Dakin’s solution does not induce phagocytosis but can reduce the microbial load, making it easier for immune cells to clear the wound.
Choice D rationale
Primary intention refers to the direct healing of a wound with minimal tissue loss, typically through suturing. Dakin’s solution is not used for primary intention but for treating wounds that are already open and require cleaning.
