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. Bowel sounds are hypoactive in all four quadrants, which is expected after an appendectomy due to anesthesia and decreased peristalsis. This is not a finding that needs to be reported to the provider.
• B. Oxygen saturation is 93% on room air, which is below the normal range of 95% to 100%. This could indicate impaired gas exchange, respiratory depression, or infection. This is a finding that needs to be reported to the provider.
• C. Nausea is a common feature of appendicitis and should go away with appendectomy. This finding should, therefore, be reported to the healthcare provider.
• D. Vomiting is also a common side effect of morphine and anesthesia, and can be managed with antiemetics and fluids. This is not a finding that needs to be reported to the provider unless it persists or interferes with oral intake.
• E. Pain level is 6 on a scale of 0 to 10.The client received morphine as prescribed at 1815, and the pain level is still significant. This isa finding that needs to be reported to the provider
• F. Heart rate is 110/min, which is above the normal range of 60 to 100/min. This could indicate pain, anxiety, dehydration, infection, or bleeding. This is a finding that needs to be reported to the provider.
• G. Incision characteristics are clean and dry, which is expected after an appendectomy. However, the nurse should monitor for signs of infection such as redness, swelling, warmth, drainage, or odor. This is a finding that needs to be reported to the provider if any signs of infection are present.
• H. Lungs sounds are clear on auscultation, which is expected after an appendectomy. However, the nurse should encourage deep breathing and coughing exercises to prevent atelectasis and pneumonia. This is a finding that needs to be reported to the provider if any abnormal lung sounds are heard such as crackles, wheezes, or diminished breath sounds.

- A is incorrect because massaging bony prominences on the client's left side can increase the risk of skin breakdown and pressure ulcers. The nurse should avoid applying pressure to areas with impaired circulation or sensation.

- B is correct because supporting the client's left arm on a pillow while sitting can prevent edema, contractures, and nerve damage. The nurse should also encourage the client to perform active and passive range of motion exercises on their left arm.

- C is incorrect because positioning the bedside table on the client's left side can discourage the client from using their right side, which can lead to neglect and learned nonuse. The nurse should position the bedside table on the client's right side and encourage them to reach for items with their right hand.

- D is incorrect because placing the client's cane on their left side while ambulating can cause instability and falls. The nurse should place the cane on the client's right side and instruct them to move their left leg and cane together, followed by their right leg.
