A nurse preceptor is evaluating the performance of a newly licensed nurse. Which of the following actions by the newly licensed nurse requires intervention by the preceptor?

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 vasoocclusive 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.

Assign the client to a private room with negative air pressure.

Rationale:

• A. Incorrect. Restricting fresh flowers from the client's room is not necessary for infection control purposes. However, some clients with pulmonary tuberculosis may have hypersensitivity reactions to certain plants or flowers, so the nurse should assess the client's allergies before allowing them in the room.
• B. Incorrect. Maintaining a distance of 1.8 m (6 feet) from the client is not sufficient to prevent transmission of tuberculosis. Visitors should also wear a HEPA respirator and limit their contact time with the client.
• C. Incorrect. A surgical mask is not adequate to protect the nurse from inhaling airborne droplet nuclei that contain Mycobacterium tuberculosis. The nurse should wear a high-efficiency particulate air (HEPA) respirator when providing client care.
• D. Correct. Assigning the client to a private room with negative air pressure is the most effective way to prevent the spread of tuberculosis to other clients and staff members. The room should have at least six air exchanges per hour and an exhaust system that vents directly to the outside.
