Correct Answer: B

Rationale: Monitoring the client's oxygen saturation intermittently is the most appropriate action when providing care for a client with disseminated intravascular coagulation (DIC) who has a nursing diagnosis of Impaired Gas Exchange. DIC can lead to a variety of complications, including inadequate oxygenation of tissues due to abnormal clotting and bleeding. By monitoring the client's oxygen saturation levels, the healthcare team can assess the effectiveness of gas exchange and adjust interventions as needed to optimize oxygenation. This action helps in early detection of worsening gas exchange and guides appropriate interventions to address any respiratory issues promptly. Placing the client in a low-Fowler position may not be suitable for all patients with DIC, encouraging frequent ambulation could be risky due to the increased bleeding tendency, and using continuous endotracheal suctioning is not recommended as it can lead to aggravation of respiratory issues and increase the risk of further complications.

Correct Answer: C

Rationale: In a client with deep venous thrombosis (DVT), the priority problem would be peripheral perfusion. DVT is a condition where a blood clot forms in a vein deep within the body, usually in the lower extremities. This clot can impede blood flow in the affected vein, leading to compromised circulation to the surrounding tissues. Poor peripheral perfusion can result in tissue ischemia and potential tissue necrosis. Monitoring and ensuring adequate peripheral perfusion is crucial to prevent tissue damage and further complications such as pulmonary embolism. Therefore, addressing and improving peripheral perfusion would be the priority in caring for a client with DVT.

Correct Answer: A

Rationale: A. A slight increase in pulse is a common finding in hypovolemic shock. The body compensates for the decreased blood volume by increasing the heart rate to maintain adequate perfusion.

Correct Answer: B

Rationale: B. It is essential for the patient to avoid taking muscle relaxants before the electromyogram test because these medications can affect the results by altering muscle activity and electrical signals, which are critical for diagnosing muscle and nerve disorders.

Correct Answer: A

Rationale: A. Regular exercise has been shown to reduce the risk of developing colon cancer. Exercise helps in maintaining a healthy weight, supporting the immune system, and promoting overall health.
