83
Q

A nurse is caring for a client who is at high risk for aspiration. Which of the following actions should the nurse take?
A. Give the client thin liquids.
B. Instruct the client to tuck their chin when swallowing.
C. Have the client use a straw.
D. Encourage the client to lie down and rest after meals.

A

A. Thin liquids increase the client’s risk for aspiration.
B. CORRECT: Tucking the chin when swallowing allows food to pass down the esophagus more easily.
C. Using a straw increases the client’s risk for aspiration.
D. Sitting for an hour after meals helps prevent gastroesophageal reflux and possible aspiration of stomach contents after a meal.

84
Q

A nurse is preparing a presentation about basic nutrients for a group of high school athletes. She should explain that which of the following nutrients provides the body with the most energy?
A. Fat
B. Protein
C. Glycogen
D. Carbohydrates

A

A. Although the body gets more than half of its energy supply from fat, it is an inefficient means of obtaining energy. It produces end products the body has to excrete, and it requires energy from another source to burn the fat.
B. Protein can supply energy, but it has other very essential and specific functions that only it can perform. So it is not the body’s priority energy source.
C. Glycogen, which the body stores in the liver, is a backup source of energy, not a primary or priority source.
D. CORRECT: Carbohydrates are the body’s greatest energy source; providing energy for cells is their primary function. They provide glucose, which burns completely and efficiently without end products to excrete. They are also a ready source of energy, and they spare proteins from depletion.

85
Q

A nurse is caring for a client who requires a low‑residue diet. The nurse should expect to see which of the following foods on the client’s meal tray?
A. Cooked barley
B. Pureed broccoli
C. Vanilla custard
D. Lentil soup

A

A. Whole grains (barley and oats) are high in fiber and thus inappropriate components of a low‑residue diet.
B. Raw and gas‑producing vegetables (broccoli and the cabbage in coleslaw) are high in fiber and thus inappropriate components of a low‑residue diet.
C. CORRECT: A low‑residue diet consists of foods that are low in fiber and easy to digest. Dairy products and eggs (custard and yogurt) are appropriate for a low‑residue diet.
D. Legumes (lentils and black beans) are high in fiber and thus inappropriate components of a low‑residue diet.

86
Q

A nurse is caring for a client who weighs 80 kg (176 lb) and is 1.6 m (5 ft 3 in) tall. Calculate the body mass index (BMI) and determine whether this client’s BMI indicates a healthy weight, underweight, overweight, or obese.

A

BMI = weight (kg) ÷ height (m2).
Step 1: Client’s weight (kg) and height (m) = 80 kg and 1.6 m
Step 2: 1.6 × 1.6 = 2.56 m2
Step 3: 80 ÷ 2.56 = 31.25
A BMI greater than 30 identifies obesity.

87
Q

A nurse in a senior center is counseling a group of older adults about their nutritional needs and considerations. Which of the following information should the nurse include? (Select all that apply.)
A. Older adults are more prone to dehydration than younger adults are.
B. Older adults need the same amount of most vitamins and minerals as younger adults do.
C. Many older men and women need calcium supplementation.
D. Older adults need more calories than they did when they were younger.
E. Older adults should consume a diet low in carbohydrates.

A

A. CORRECT: Sensations of thirst diminish with age, leaving older adults more prone to dehydration.
B. CORRECT: These requirements do not change from middle adulthood to older adulthood. However, some older adults need additional vitamin and mineral supplements to treat or prevent specific deficiencies.
C. CORRECT: If older adults ingest insufficient calcium in the diet, they need supplements to help prevent bone demineralization (osteoporosis).
D. Older adults have a slower metabolic rate, so they require less energy (unless they are very active), and therefore need fewer calories.
E. M any older adults need more carbohydrates for the fiber and bulk they contain. They should, however, reduce their intake of fats and of “empty” calories (pastries and soda pop).
