Correct Answer is D
Explanation
Rationale:
A. While the client's feelings about never marrying are important, they do not represent an immediate health risk or safety concern.
B. Poorly fitting dentures can affect the client's quality of life and ability to eat, but they do not represent an immediate health risk or safety concern.
C. While having no living family can be a social concern, it does not represent an immediate health risk or safety concern.
D. The client being sedentary throughout most of the day is a risk factor for numerous health problems, including cardiovascular disease, obesity, and decreased mobility. It is also a modifiable risk factor that can be addressed to improve the client's health and quality of life. Encouraging the client to engage in regular physical activity is a priority.
Correct Answer is ["A"]
Explanation
A. A hydrocolloid dressing is a type of dressing that is used for wounds with minimal exudate, such as the wound on the client's coccyx described in the scenario. It provides a moist environment for wound healing and can help with pain relief. This type of dressing is suitable for wounds with granulation tissue and can help protect the wound from further damage while promoting healing.
B. A dry gauze is not appropriate for this type of wound as it does not provide the necessary moist environment for healing and may adhere to the wound, causing damage upon removal.
C. A hydrogel dressing is typically used for wounds with moderate to heavy exudate.
D. An alginate dressing is typically used for wounds with moderate to heavy exudate. These dressings may not be suitable for the described wound with minimal exudate.
E. A transparent dressing may not be suitable for a wound with granulation tissue and moderate exudate, as it may not provide adequate protection and moisture to the wound.
