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: A

Rationale: The statement "You'll give us written instructions before we go home, correct?" reflects the mother's readiness to learn. This statement shows that the mother is actively seeking out resources and tools to help her understand and remember the instructions for giving her premature baby a bath. It indicates that she is willing to take responsibility for her baby's care and is thinking ahead to ensure she has the necessary information for when she is on her own at home. This statement demonstrates engagement and a proactive approach to learning, which are essential for successfully caring for a premature baby in a NICU setting.

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: 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.
