While assessing capillary refill in a patient's nailbed, you observe that the refill time is 4 seconds. What should be your priority action?

Choice A reason: Justice refers to the ethical obligation to treat all patients fairly and distribute resources equitably. While the nurse must apply clinical standards fairly to all patients, the specific act of discontinuing a harmful medication to prevent further injury is centered on safety and the avoidance of harm rather than the distribution of care.

Choice B reason: Nonmaleficence is the fundamental ethical principle of "doing no harm." When a nurse identifies that a prescribed treatment is causing adverse effects that are more detrimental to the patient's health than the condition being treated, they have an ethical duty to intervene. Stopping the medication directly prevents further iatrogenic injury to the patient.

Choice C reason: Autonomy involves the patient's right to make their own decisions about their healthcare. While a patient may choose to stop a medication, the scenario describes the nurse taking action based on a clinical observation of harm. If the nurse makes this decision in the patient's interest to prevent injury, it is an application of professional ethics rather than a reflection of patient self-determination.

Choice D reason: Beneficence is the duty to act in ways that benefit the patient. While stopping a harmful drug is beneficial, the primary focus of stopping a negative or toxic effect is the avoidance of harm, which is the specific definition of nonmaleficence. Beneficence is usually associated with proactive treatments and promoting overall wellness.

Choice A reason: Pale skin color is referred to as pallor. This occurs due to a decrease in the number of circulating red blood cells or reduced blood flow to the skin, commonly seen in conditions like anemia, shock, or local arterial insufficiency. It is distinct from the blue tint seen in cyanosis.

Choice B reason: A yellowish discoloration of the skin, sclera, and mucous membranes is known as jaundice or icterus. This condition is typically caused by elevated levels of bilirubin in the blood, often signaling hepatic dysfunction, biliary obstruction, or excessive hemolysis of red blood cells.

Choice C reason: Redness of the skin is termed erythema. This is caused by hyperemia, or increased blood flow to the capillaries near the skin surface, often due to inflammation, fever, or localized infection. Purple tones may indicate ecchymosis or deep tissue injury, rather than a lack of oxygen.

Choice D reason: Cyanosis is a clinical sign characterized by a bluish or grayish tint to the skin and mucous membranes. This occurs when the concentration of deoxygenated hemoglobin in the peripheral capillaries exceeds 5 g/dL, indicating that the tissues are not receiving adequate oxygen from the blood.
