A nurse on a medical-surgical unit is caring for a client who has a new diagnosis of terminal cancer. The client tells the nurse that they would like to go home to be with family and loved ones. Which of the following actions should the nurse take?

A. Hypoxemia is a condition of low oxygen levels in the blood. PEEP can actually improve oxygenation by preventing alveolar collapse and increasing functional residual capacity.

B. Tension pneumothorax is a life-threatening condition of air accumulation in the pleural space that causes increased intrathoracic pressure and compresses the lungs, heart, and great vessels. PEEP can increase the risk of tension pneumothorax by creating excessive positive pressure in the airways and alveoli.

C. Malignant hypertension is a severe form of high blood pressure that can cause organ damage and stroke. PEEP can cause a transient increase in blood pressure due to increased intrathoracic pressure, but it does not cause malignant hypertension.

D. Atelectasis is a condition of partial or complete lung collapse due to alveolar collapse or obstruction. PEEP can prevent or treat atelectasis by maintaining positive pressure in the airways and alveoli.

A. Assess peripheral circulation hourly. This is correct because clients with SCD are at risk of vaso-occlusive crisis, which can impair blood flow to the extremities and cause tissue ischemia and necrosis. The nurse should monitor for signs of poor circulation such as pallor, coolness, numbness, or pain.

B. Assess the client's mouth every 8 hr. This is correct because clients with SCD are prone to oral ulcers, infections, and dental problems due to chronic anemia and reduced oxygen delivery to the oral mucosa. The nurse should inspect the mouth for lesions, bleeding, inflammation, or infection and provide oral hygiene as needed.

C. Use humidification with oxygen therapy. Administer IV fluids. This is correct because clients with SCD need adequate hydration and oxygenation to prevent sickling of red blood cells and further complications. Humidification helps moisten the airways and prevent dehydration of the mucous membranes. IV fluids help maintain fluid and electrolyte balance and reduce blood viscosity.

D. Raise the knee position on the client's bed. This is incorrect because this can impede venous return and worsen peripheral circulation. The nurse should keep the client's extremities in a neutral position and avoid tight or restrictive clothing or devices.

E. Use an automated blood pressure cuff on the client's arm. Prepare for platelet transfusion. This is incorrect because this can cause mechanical trauma to the arm and trigger a vaso-occlusive crisis. The nurse should use a manual blood pressure cuff and avoid applying pressure to the arm. Platelet transfusion is not indicated for clients with SCD unless they have thrombocytopenia or bleeding.
