A nurse in a community clinic is collecting data from an older adult client who has a body mass index of 17.5. When evaluating the client for dehydration, the nurse should look for which of the following indications of fluid-volume deficit?
Tenting
Protruding eyeballs
Elevated blood pressure
Dry mucous membranes
The Correct Answer is A
A. Tenting
Tenting refers to the delayed recoil of the skin when pinched. In a dehydrated state, the skin loses elasticity, leading to tenting due to decreased skin turgor. This is a specific sign of fluid-volume deficit.
B. Protruding eyeballs
Protruding eyeballs are not typically associated with dehydration. This could be related to other conditions such as thyroid dysfunction, but it is not a specific indicator of fluid-volume deficit.
C. Elevated blood pressure
Elevated blood pressure is not a typical sign of dehydration. In fact, dehydration often leads to a decrease in blood pressure due to reduced blood volume.
D. Dry mucous membranes
Dry mucous membranes can be an indication of dehydration, but in the context of the question, tenting (Option A) is a more specific sign related to skin turgor and is commonly assessed when evaluating for dehydration.

Correct Answer is D
Explanation
A. Yogurt:
Yogurt is not a significant source of iron. While yogurt provides various nutritional benefits, it is not considered an iron-rich food.
B. Oranges:
Oranges are a good source of vitamin C, which enhances the absorption of non-heme iron from plant-based foods. However, oranges themselves do not contain substantial amounts of iron. The combination of vitamin C-rich foods with iron-rich foods can be beneficial for iron absorption.
C. Turnips:
Turnips are a vegetable that, while nutritious, is not particularly high in iron. Additionally, the iron in plant-based foods like turnips is non-heme iron, which is less easily absorbed by the body compared to heme iron found in animal products.
D. Roast beef:
Roast beef is a good source of heme iron, which is more easily absorbed by the body. Red meat, such as roast beef, is a valuable dietary source of iron, especially for individuals with iron deficiency.
Correct Answer is B
Explanation
A. “Most of my calories each day should be from fats.”
This statement is not accurate. While fats are essential for a balanced diet, it is not recommended for the majority of calories to come from fats. The emphasis should be on a variety of macronutrients, including carbohydrates and proteins.
B. “I should eat more calories from complex carbohydrates than anything else.”
This is the correct choice. Individuals with diabetes are often encouraged to obtain the majority of their calories from complex carbohydrates. These include whole grains, vegetables, and legumes, which have a slower impact on blood glucose levels.
C. “Simple sugars are needed more than other calorie sources.”
This statement is not accurate for individuals with diabetes. Simple sugars can lead to rapid spikes in blood glucose levels and should be consumed in moderation.
D. “Protein should be my main source of calories.”
This statement is not accurate. While protein is important for overall health, it is not recommended for protein to be the main source of calories. A balanced diet with an emphasis on complex carbohydrates is typically recommended.
