A nurse is teaching a class about using niacin to reduce LDL cholesterol.
The nurse should include in the teaching that which of the following conditions is a contraindication for receiving this medication?

- A. Contacting the facility chaplain to visit with the client may be helpful for some clients who have spiritual needs or concerns, but it does not address the client's expressed desire to go home. The nurse should respect the client's wishes and preferences and not impose their own beliefs or values on them.

- B. Explaining the process of leaving the facility against medical advice may discourage the client from pursuing their goal of going home and imply that they are making a wrong decision. The nurse should not judge or coerce the client, but rather provide them with information and support to make an informed choice.

- C. Making a referral for social services is the best action for the nurse to take, as it will help the client access resources and services that can facilitate their discharge planning and home care arrangements. The social worker can also assist with financial, legal, or emotional issues that may arise from the terminal diagnosis.

- D. Encouraging the client to continue with inpatient care may go against the client's wishes and values, and may cause them more distress and suffering. The nurse should respect the client's autonomy and dignity and support their quality of life goals.

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.
