A nurse is reviewing the laboratory results of a female client who has liver dysfunction a receiving a continuous tube feeding. Which of the findings should the nurse identify as a protein deficiency?
Albumin 3.1 g/dL (3.5 to 5.0 g/dL)
Transferrin 400 mg/dL (250 to 380 mg/dL)
Uric acid 2.3 mg/dL (2.7 to 7.3 mg/dL)
Total iron-binding capacity 488 mcg/dL (250 to 460 mcg/dL)
The Correct Answer is A
A. Albumin 3.1 g/dL (3.5 to 5.0 g/dL)
Albumin is a protein produced by the liver, and its levels are commonly used as an indicator of nutritional status, particularly protein status. In clients with liver dysfunction and receiving continuous tube feeding, a low albumin level indicates protein deficiency. Albumin plays a crucial role in maintaining oncotic pressure in the blood vessels, and decreased levels can lead to fluid shifts and edema, among other complications.
B. Transferrin 400 mg/dL (250 to 380 mg/dL):
Transferrin is a protein involved in iron transport. While high transferrin levels may indicate iron deficiency, they do not directly reflect protein deficiency.
C. Uric acid 2.3 mg/dL (2.7 to 7.3 mg/dL):
Uric acid is a waste product of metabolism. Low uric acid levels are not indicative of protein deficiency; instead, they may be seen in conditions such as liver dysfunction or decreased production of uric acid.
D. Total iron-binding capacity 488 mcg/dL (250 to 460 mcg/dL):
Total iron-binding capacity measures the amount of iron that can be bound by transferrin. Elevated total iron-binding capacity may indicate iron deficiency, but it does not directly reflect protein deficiency.

Correct Answer is A
Explanation
A. "I will walk three times per week."
Regular weight-bearing exercises, such as walking, are beneficial for maintaining bone density and reducing the risk of osteoporosis in older adults. Weight-bearing activities help stimulate bone formation and strengthen bones. Therefore, the client's statement about walking three times per week demonstrates an understanding of an effective measure for reducing the risk of osteoporosis.
B. "I will avoid exposure to the sun." - Exposure to sunlight is essential for vitamin D synthesis, which helps the body absorb calcium and maintain bone health. Therefore, avoiding sunlight would not be beneficial for reducing the risk of osteoporosis.
C. "I will decrease my intake of dairy products." - Dairy products are a rich source of calcium, which is crucial for bone health. Decreasing intake of dairy products may lead to inadequate calcium intake, increasing the risk of osteoporosis.
D. "I will take 250 milligrams of calcium once per day." - While calcium supplementation is important for maintaining bone health, the recommended daily intake for older adults is higher than 250 milligrams. The client's statement suggests an inadequate understanding of calcium supplementation for osteoporosis prevention.
Correct Answer is D
Explanation
A. Move items in the room away from the client: During a seizure, the client may have uncontrolled movements that could cause them to hit nearby objects and potentially injure themselves. Moving items away from the client helps create a safer environment and reduces the risk of injury from contact with objects.
B. Loosen the client's clothing: Seizures can lead to muscle contractions and movements that might constrict the client's clothing, particularly around the neck or chest area. Loosening the client's clothing helps ensure that their breathing is not restricted during the seizure.
C. Turn the client onto their side: Turning the client onto their side is an important step for airway protection. During a seizure, there is a risk of saliva or vomit obstructing the airway, which can lead to aspiration. Turning the client onto their side helps prevent aspiration by allowing any fluids to drain out safely and maintaining an open airway.
D. Help the client lie on the floor: If the client is seated in a chair during a seizure, it's safer to assist them in lying on the floor. This action prevents the client from falling out of the chair and potentially sustaining injuries from the fall. Once on the floor, the nurse can continue to monitor the client and provide appropriate care and support.
