Concepts and Cases in Nursing Ethics Test Bank

Correct Answer: D

Rationale: Terazosin is an alpha-1 adrenergic receptor blocker. By blocking alpha-1 receptors in the vascular smooth muscle, terazosin causes dilation of both arteries and veins, leading to reduced peripheral vascular resistance and decreased blood pressure. This dilation effect is achieved by preventing the binding of norepinephrine to alpha-1 receptors, thereby inhibiting vasoconstriction. Terazosin is commonly used in the treatment of hypertension to help lower blood pressure by reducing the workload on the heart and improving blood flow to organs and tissues.

Correct Answer: B

Rationale: After a stroke, sensory-perceptual changes such as impaired proprioception, altered sensation, and decreased awareness of the affected side can increase the client's risk for injury. These changes can result in difficulties with balance, coordination, and spatial awareness, making the individual more prone to falls and accidents. It is important to implement safety measures and interventions to minimize the risk of injury in these clients, such as providing a structured environment, using assistive devices, and encouraging regular monitoring and assistance as needed.

Correct Answer: A

Rationale: In a patient with a newly created ileal diversion with a continent reservoir, demonstrating care for the collection device signifies that the patient has understood the importance of maintaining hygiene and proper management of the device. This behavior indicates that the teaching provided by the nurse has been effective in helping the patient take care of the diversion and prevent complications such as infection or skin irritation. Understanding how to care for the collection device is crucial for the patient's overall well-being and quality of life with the continent reservoir.

Correct Answer: A

Rationale: A. Initiate oxygen therapy: Providing oxygen therapy is appropriate to ensure adequate oxygenation and tissue perfusion during episodes of paroxysmal supraventricular tachycardia.

Correct Answer: D

Rationale: Crepitation refers to a grating sound or sensation that occurs when there is rubbing together of the roughened articular surfaces of bones within a joint. It is commonly associated with conditions such as osteoarthritis or joint injury. Therefore, if the nurse hears a grating sound while assessing the range of motion of a patient's hip, the appropriate documentation of this finding would be crepitation.
