A client is diagnosed with a brain tumor. The nurse's assessment reveals that the client has difficulty interpreting visual stimuli.

Based on these findings, the nurse suspects injury to which lobe of the brain?

Choice A rationale

A 5% deficit in body weight and increased caloric need alone do not warrant the initiation of parenteral nutrition (PN). PN is typically reserved for situations where oral or enteral feeding is not feasible or safe.

Choice B rationale

Significant risk of aspiration and decreased level of consciousness may necessitate alternative feeding methods, such as enteral feeding via a nasogastric or gastrostomy tube. PN is considered when enteral feeding is not possible.

Choice C rationale

Calorie deficit, muscle wasting, and low electrolyte levels indicate malnutrition, but PN is initiated when other feeding methods are inadequate or unsafe.

Choice D rationale

Inability to take in adequate oral food or fluids within 7 days is a clear indication for initiating PN. This ensures the patient receives essential nutrients and prevents further deterioration of their nutritional status.

Choice A rationale

Irregular bones have complex shapes that do not fit into the other categories (long, short, or flat bones). They include bones such as the vertebrae and facial bones, which have specialized functions but are not primarily responsible for protecting vital organs.

Choice B rationale

Flat bones, such as the sternum, ribs, and skull bones, are designed to protect vital organs. They provide broad surfaces for muscle attachment and serve as protective barriers for organs like the brain, heart, and lungs.

Choice C rationale

Long bones, such as the femur and humerus, are primarily responsible for supporting the weight of the body and facilitating movement. While they contribute to the overall structure of the body, they are not specifically designed for organ protection.

Choice D rationale

Short bones, such as the carpals and tarsals, provide support and stability with limited movement. They are not primarily involved in the protection of vital organs.
