Nursing Elites

1. Among people who are ill, significant weight loss may be masked by?

• A. dehydration
• B. a large tumor
• C. drug therapy
• D. fluid retention

Correct answer: D

Rationale: Fluid retention can mask weight loss in ill individuals as the retained fluid adds to body weight, making it difficult to detect true fat or muscle loss. Dehydration (Choice A) would actually lead to weight loss rather than masking it. While a large tumor (Choice B) could contribute to weight loss, it would not mask the weight loss itself. Drug therapy (Choice C) may cause side effects, including weight changes, but it is unlikely to mask significant weight loss in the same way that fluid retention does.

2. A nurse is caring for a client who has cancer and is receiving total parenteral nutrition (TPN). Which of the following lab values indicates the treatment is effective?

• A. Hct 43%
• B. WBC 8,000/uL
• C. Albumin 4.2 g/dL
• D. Calcium 9.4 mg/dL

Correct answer: C

Rationale: The correct answer is Albumin 4.2 g/dL. Albumin is a protein produced by the liver and is a key indicator of nutritional status. In a client receiving total parenteral nutrition (TPN), an increase in albumin level indicates that the treatment is effective in providing adequate nutrition support. Hct (hematocrit), WBC (white blood cell count), and calcium levels are not direct indicators of the effectiveness of TPN in this context.

3. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?

• A. hemoglobin
• B. transferrin
• C. myoglobin
• D. hepcidin

Correct answer: A

Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.

4. A healthcare provider is teaching a client about nutritional requirements necessary to promote wound healing. Which of the following nutrients should the provider include in the teaching?

• A. Protein
• B. Calcium
• C. Vitamin B1
• D. Vitamin D

Correct answer: A

Rationale: Protein is crucial for wound healing as it plays a vital role in tissue repair and synthesis. Calcium is important for bone health but not directly related to wound healing. Vitamin B1 is essential for energy production but not specifically significant for wound healing. Vitamin D is essential for bone health and immune function but is not a primary nutrient emphasized for wound healing.

5. The past history of Camila would most probably reveal that her premorbid personality is:

• A. schizoid
• B. extrovert
• C. ambivert
• D. cycloid

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
