A nurse is reviewing a client's laboratory results for effectiveness of total parenteral nutrition (TPN). Which of the following laboratory values is the best indicator for the nurse to monitor for short-term effectiveness of the TPN?
Hemoglobin
Transferrin
Prealbumin
Total albumin
The Correct Answer is C
A. Hemoglobin levels primarily reflect the oxygen-carrying capacity of red blood cells and are not specific to nutritional status.
B. Transferrin levels reflect iron-binding capacity and may be influenced by factors other than nutrition.
C. Prealbumin levels have a shorter half-life compared to total albumin and can provide a more immediate assessment of nutritional status and the effectiveness of TPN in the short term.
D. Total albumin levels reflect longer-term protein status and may not change significantly in the short term with TPN administration.

Correct Answer is A
Explanation
A. Eating a larger meal at breakfast and smaller meals throughout the day can help regulate appetite, reduce overall caloric intake, and promote weight loss.
B. Setting a weight loss goal of 2.5 pounds per week may be unrealistic or unsafe for some individuals. A more moderate and sustainable goal, such as 1-2 pounds per week, is typically recommended.
C. Meal replacement shakes can be a convenient option for some individuals as part of a weight loss plan, but they do not inherently cause weight gain. However, it's important to choose meal replacements with appropriate nutritional content and to use them as part of a balanced diet.
D. Drinking water with meals can help promote satiety and may prevent overeating, but it is not the only behavioral modification necessary for successful weight loss.
Correct Answer is B
Explanation
A. Anticholinesterase medications, such as pyridostigmine, are commonly prescribed for myasthenia gravis. They should be taken as prescribed by the healthcare provider, usually on an empty stomach, to optimize absorption.
B. Positioning the head of the client's bed to 40° while eating helps prevent aspiration and choking by facilitating swallowing in clients with myasthenia gravis.
C. Providing the client with food cut into small bites can make swallowing easier but does not address the risk of aspiration associated with myasthenia gravis.
D. Encouraging the client to lie down after eating increases the risk of aspiration and should be avoided in clients with myasthenia gravis.
