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
Explanation
Choice A rationale
The High-Fowler’s position, with the client sitting upright at a 90-degree angle, is ideal for abdominal wound irrigation as it reduces the risk of fluid accumulation in the wound area and promotes drainage.
Choice B rationale
The side-lying position is not typically used for abdominal wound irrigation because it can cause pooling of the irrigation solution and does not facilitate easy access to the wound site.
Choice C rationale
The supine position, with the client lying flat on their back, is not suitable for abdominal wound irrigation as it can lead to fluid retention in the wound and does not aid in drainage.
Choice D rationale
The dorsal recumbent position, with the client lying on their back with knees bent, is also not optimal for abdominal wound irrigation due to the potential for fluid to collect in the wound area.
Correct Answer is A
Explanation
Choice A rationale
Keeping a superficial wound moist can promote faster healing. A moist environment helps to protect the new tissue, prevent the wound from drying out and forming a scab, which can slow down the healing process. It also allows cells to move across the wound more easily, which can speed up healing.
Choice B rationale
While it was once common practice to keep wounds dry, research has shown that a dry environment can actually slow down the healing process by causing cells to dehydrate and scabs to form, which can impede the growth of new tissue.
Choice C rationale
A wet-to-dry dressing is typically used for mechanical debridement and not for the purpose of speeding up healing. This type of dressing can be useful for removing dead tissue but is not necessarily conducive to the fastest healing of superficial wounds.
Choice D rationale
Debridement is the removal of dead or infected tissue from a wound to help healing. While it is an important part of wound care, the act of debridement itself does not speed up healing; rather, it sets the stage for it by cleaning the wound.
