A nurse is caring for a client who is participating in a research study for an experimental chemotherapy medication. After three treatments, the experimental medication is discontinued due to evidence of rapidly advancing kidney failure. Which of the following ethical principles was demonstrated?

Choice A rationale:

Dyspnea (shortness of breath) is a common finding in clients with emphysema. Emphysema is a chronic obstructive pulmonary disease characterized by the destruction of lung tissue, leading to reduced lung elasticity and airflow limitation, which can result in difficulty breathing.

Choice B rationale:

Clubbing of the fingers is another expected finding in clients with advanced emphysema. Clubbing is the swelling and rounding of the fingertips, often associated with chronic respiratory conditions. It is thought to be a result of chronic hypoxia and inadequate oxygenation.

Choice C rationale:

Deep respirations are not typically associated with emphysema. Clients with emphysema often exhibit shallow, rapid respirations due to the loss of lung tissue elasticity, which impairs the normal respiratory mechanics.

Choice D rationale:

Bradycardia (slow heart rate) is not a common finding in emphysema. Emphysema primarily affects the respiratory system and does not directly influence heart rate. Bradycardia could be related to other factors but is not a characteristic finding of emphysema.

Choice E rationale:

Barrel chest is a classic physical finding in clients with emphysema. It results from the hyperinflation of the lungs due to the trapping of air in the damaged alveoli. This gives the chest a rounded appearance, similar to the shape of a barrel.

The correct answer is choice A. Transparent dressing.

Choice A rationale:

Transparent dressings are appropriate for stage I pressure ulcers. These dressings provide a moist environment that promotes healing and protects the wound from external contaminants. They are also transparent, allowing the nurse to monitor the wound without removing the dressing. As stage I pressure ulcers involve intact skin with non-blanchable redness, these dressings aid in preventing friction and shear forces that could exacerbate the injury.

Choice B rationale:

Alginate dressings (Choice B) are not suitable for stage I pressure ulcers. Alginate dressings are highly absorbent and are generally used for wounds with moderate to heavy exudate, such as infected wounds or those with necrotic tissue. They may not be the best choice for a stage I pressure ulcer, which is characterized by superficial skin involvement without exudate or necrosis.

Choice C rationale:

Hydrogel dressings (Choice C) are beneficial for wounds with minimal to no exudate, but they are more appropriate for partial-thickness wounds, burns, or dry wounds. They provide a moist environment and promote autolytic debridement. However, in the case of a stage I pressure ulcer, where the skin is intact and there is no exudate, hydrogel dressings may not be the ideal choice.

Choice D rationale:

Wet-to-dry gauze dressings (Choice D) involve placing moist saline gauze onto a wound bed and allowing it to dry before removal. This method is used for mechanical debridement of wounds with necrotic tissue, and it's not suitable for a stage I pressure ulcer. In fact, using wet-to-dry dressings on a superficial wound could cause trauma and hinder healing.
