What causes brown pigmentation of the lower extremities in clients with venous stasis?

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.

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: 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: C

Rationale: The priority outcome for a client with deep vein thrombosis (DVT) receiving intravenous heparin is to prevent bleeding. Heparin is an anticoagulant medication used to prevent the formation of blood clots, but one of its potential side effects is bleeding due to its ability to prevent blood clotting. It is crucial to closely monitor the client for signs of bleeding while on heparin therapy, such as easy bruising, black or tarry stools, blood in the urine, or excessive bleeding from wounds. Preventing bleeding is essential to avoid complications associated with anticoagulant therapy.

Correct Answer: B

Rationale: Endocarditis is a common complication that individuals with repaired congenital heart defects may still be at risk for. Endocarditis is an infection of the inner lining of the heart chambers and valves. The altered structure of the heart tissue from the previous defect and surgery can create an increased risk for bacterial growth and infection. Patients with a history of congenital heart defects should be monitored for signs and symptoms of endocarditis, such as fever, fatigue, new heart murmurs, and evidence of systemic embolization. Prophylactic antibiotics before certain dental and surgical procedures may be recommended to prevent endocarditis in this population. Therefore, the nurse should be vigilant in monitoring for any symptoms suggestive of endocarditis in this client.

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: 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: Paroxysmal nocturnal dyspnea is a symptom commonly seen in patients with congestive heart failure (CHF). It is characterized by sudden awakening from sleep due to difficulty breathing and feeling of suffocation. This occurs because when the patient lies down, the redistribution of fluid in the body leads to increased fluid in the lungs, causing difficulty in breathing. Patients with CHF often experience worsening of symptoms at night, including paroxysmal nocturnal dyspnea, due to the shift in fluid dynamics in a supine position. Therefore, the client in this scenario is likely experiencing paroxysmal nocturnal dyspnea, a classic symptom of heart failure exacerbation.
