A nurse is teaching a class about Kohlberg’s theory of moral development. The nurse should instruct that which of the following stages involves challenging rules that impinge on the rights of others?

Choice A reason: Exercise is modifiable, as increasing physical activity improves cardiovascular health by reducing LDL cholesterol, blood pressure, and insulin resistance. It enhances endothelial function, promotes vasodilation, and increases cardiac efficiency, lowering the risk of atherosclerosis and coronary artery disease through improved lipid profiles and metabolic health.

Choice B reason: Smoking is a modifiable risk factor, as cessation reduces heart disease risk. Nicotine and carbon monoxide damage endothelial cells, increase LDL oxidation, and promote platelet aggregation, accelerating atherosclerosis. Quitting restores vascular function, decreases inflammation, and lowers the risk of myocardial infarction within months.

Choice C reason: Family history is a non-modifiable risk factor, as genetic predisposition influences lipid metabolism and vascular health. Inherited conditions like familial hypercholesterolemia increase LDL levels, promoting atherosclerosis. While lifestyle can mitigate some genetic risks, family history itself cannot be changed, remaining a fixed contributor to heart disease risk.

Choice D reason: Age is a non-modifiable risk factor, as advancing age increases arterial stiffness and endothelial dysfunction, promoting atherosclerosis. Cumulative exposure to risk factors like hypertension or hyperlipidemia exacerbates cardiovascular damage over time. While lifestyle interventions help, age itself cannot be altered, making it a fixed risk factor.

Choice E reason: Diet is modifiable, as reducing saturated fats, trans fats, and sodium lowers LDL cholesterol and blood pressure. A diet rich in fruits, vegetables, and omega-3 fatty acids improves lipid profiles, reduces inflammation, and enhances vascular health, decreasing the risk of coronary artery disease and myocardial infarction.

Choice A reason: Full-thickness skin loss with visible adipose tissue characterizes a stage 3 pressure injury, not stage 1. Stage 1 involves only superficial changes, with no tissue loss or exposure of deeper structures like fat, which occurs when pressure damage extends through the dermis, making this incorrect.

Choice B reason: Full-thickness skin loss with visible bone indicates a stage 4 pressure injury, not stage 1. Stage 1 pressure injuries are limited to superficial skin changes without tissue loss. Bone exposure signifies severe tissue damage, far beyond the intact, non-blanchable skin of a stage 1 injury, making this incorrect.

Choice C reason: Partial-thickness skin loss with red tissue in the wound bed describes a stage 2 pressure injury, where the epidermis and possibly dermis are damaged, exposing a shallow wound. Stage 1 pressure injuries involve intact skin with non-blanchable redness, not tissue loss, making this an incorrect finding for a stage 1 injury.

Choice D reason: Stage 1 pressure injuries present with intact skin and non-blanchable redness over a bony prominence, indicating early pressure damage. The redness results from localized ischemia due to prolonged pressure, but the skin remains unbroken. This is the hallmark finding for stage 1, making it the correct expectation for the nurse’s assessment.
