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: 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.

Correct Answer: C

Rationale: A urine output of 200 mL in 8 hours is considered low, especially for a client with cardiomyopathy who is receiving diuretic therapy. This could indicate inadequate cardiac output or worsening heart failure. It is crucial for the nurse to notify the healthcare provider promptly so that appropriate interventions can be initiated to address the underlying cause and prevent further complications. Waiting for improvement without taking action could lead to deterioration in the client's condition.

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: B

Rationale: The brown pigmentation of the lower extremities in clients with venous stasis is primarily caused by the breakdown of red blood cells in the congested tissues. When there is venous stasis, the blood circulation is impaired, leading to a backup of blood in the lower extremities. This stagnant blood contains hemosiderin, a byproduct of red blood cell breakdown. Over time, the hemosiderin deposits in the tissues, causing the characteristic brown discoloration seen in conditions such as chronic venous insufficiency. This process is known as hemosiderin deposition and is a common consequence of venous stasis.
