215 Exam 3
SECTION 1: NUTRITION & METABOLISM
1. A nurse is performing an admission assessment on a client who has hypovolemia
due to vomiting and diarrhea. The nurse should expect which of the following
findings? (Select all that apply)
A. Bradycardia
B. Tachycardia
C. Syncope
D. Decreased skin turgor
E. Hypertension
Correct Answer: B, C, D
Explanation: Hypovolemia (fluid volume deficit) causes tachycardia as the body
compensates to maintain cardiac output. Syncope (fainting) results from decreased cerebral
perfusion. Decreased skin turgor (skin tenting) is a classic sign of dehydration. Bradycardia
and hypertension are not associated with hypovolemia .
2. 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. Proteins
B. Carbohydrates
C. Fats
D. Vitamins
Correct Answer: B
,Explanation: Carbohydrates provide nearly all the energy for the brain and are the most
quickly and easily digested energy source. They provide 4 Kcal per gram and supply
glucose, which burns completely and efficiently .
3. Which lab value is most useful in assessing a client's recent nutritional status?
A. Serum albumin
B. Hemoglobin
C. Prealbumin
D. Hematocrit
Correct Answer: C
Explanation: Prealbumin has a short half-life (~2 days), making it a sensitive marker for
acute changes in nutritional status. Albumin reflects long-term nutrition (3-week half-life).
Hemoglobin and hematocrit assess anemia, not general nutrition .
4. Which of the following are water-soluble vitamins? (Select all that apply)
A. Vitamin C
B. Vitamin B12
C. Vitamin B6
D. Vitamin A
Correct Answer: A, B, C
Explanation: Water-soluble vitamins include the B-complex vitamins and vitamin C. Vitamin
A is fat-soluble. Water-soluble vitamins are not stored in the body and must be consumed
regularly .
5. A nurse is educating a client on the proper use of fat-soluble vitamin supplements.
Which of the following statements by the client requires further teaching?
A. "I will avoid taking more than the recommended dose of vitamin A."
B. "I'll take these vitamins with meals that contain fat to help with absorption."
C. "I understand that vitamins A, D, E, and K are fat-soluble."
D. "Because these vitamins are stored in fat, I can take large doses without harm."
Correct Answer: D
Explanation: Fat-soluble vitamins can accumulate in the body and lead to toxicity if taken in
excess. The client should understand that vitamins A, D, E, and K are fat-soluble and
should be taken with meals containing fat for proper absorption .
,6. What is the primary function of carbohydrates in the body?
A. Growth and repair of body tissues
B. Primary source of energy
C. Insulation and protection of organs
D. Regulation of body temperature
Correct Answer: B
Explanation: Carbohydrates are the body's primary source of energy, providing nearly all
the energy for the brain. They are the most quickly and easily digested energy source .
7. What is the recommended maximum percentage of daily intake from fats?
A. 20%
B. 25%
C. 35%
D. 45%
Correct Answer: C
Explanation: Fats should make up no more than 35% of daily caloric intake. Fats provide
energy and vitamins, but excess can be a health hazard. They are essential for brain and
nerve function .
8. A nurse is teaching a client about the clear liquid diet. Which of the following foods
and beverages are appropriate for this diet? (Select all that apply)
A. Apple juice
B. Broth (clear)
C. Coffee with cream
D. Gelatin (without added fruit)
E. Ice pops without milk
F. Orange juice with pulp
Correct Answer: A, B, D, E
Explanation: Clear liquids include clear juices without pulp, clear broth, plain gelatin, and
clear ice pops without milk or fruit bits. Coffee with cream is not allowed because cream
makes the liquid cloudy. Orange juice with pulp contains solid particles .
9. Normal serum potassium range is:
, A. 1.5-2.5 mEq/L
B. 3.5-5.0 mEq/L
C. 5.5-7.0 mEq/L
D. 8.0-10.0 mEq/L
Correct Answer: B
Explanation: Normal potassium range is 3.5-5.0 mEq/L. Potassium is essential for fluid
volume inside cells, muscle contraction, and nerve function .
10. 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. Fresh fruit
B. Whole grain bread
C. Vanilla custard
D. Raw vegetables
Correct Answer: C
Explanation: A low-residue diet restricts foods high in fiber, such as fresh fruits, whole
grains, and raw vegetables. Vanilla custard is low in residue and appropriate for this diet .
SECTION 2: OXYGENATION & RESPIRATORY CARE
11. A nurse is caring for a postoperative client receiving 2 L/min of oxygen via nasal
cannula. The nurse notes that the client is restless and picking at the bed sheets.
What is the priority action?
A. Reorient the client to person, place, and time
B. Notify the provider and request antianxiety medication
C. Assess the client's oxygen saturation level
D. Encourage the client to rest quietly
Correct Answer: C
Explanation: Restlessness, confusion, and agitation are early signs of hypoxia, particularly
in clients at risk (e.g., postoperative, respiratory conditions). The priority action is to check
oxygenation status via pulse oximetry and assess that the prongs are functioning properly .
12. A client is being discharged home on oxygen via nasal cannula. Which of the
following statements indicates a need for further teaching?
