1. Which foods increase iron absorption when consumed with nonheme iron? (SATA)
- A. Kiwi
- B. Strawberries
- C. Coffee

2. During the detoxification stage, it is a priority for the nurse to:
- A. teach skills to recognize and respond to health threatening situations
- B. increase the client’s awareness of unsatisfactory protective behaviors
- C. implement behavior modification
- D. promote homeostasis and minimize the client’s withdrawal symptoms
Correct answer: A
Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
3. Are the following statements both true: 'Most excess energy intake, whether from protein, carbohydrate, alcohol, or fat, is stored in the liver' and 'Fat is a good source of energy, but the preferred fuel is protein'?
- A. Both statements are true
- B. Both statements are false
- C. The first statement is true, but the second is false
- D. The first statement is false, but the second is true
Correct answer: B
Rationale: Both of the given statements are false. The first statement is inaccurate because the primary location for excess energy storage is not the liver, but rather adipose tissue where it is stored as fat. While the liver does have a role in energy storage and metabolism, it is not the main storage site for excess intake. The second statement is also incorrect. Although fat and protein can be used as sources of energy, the body's preferred source of energy is carbohydrates. They break down more efficiently and are easier for the body to use. The body prefers to conserve protein for other essential functions, such as tissue repair and the production of enzymes. Therefore, protein is not the preferred fuel source.
4. What is the primary function of antioxidants in the diet?
- A. Provide energy
- B. Support muscle growth
- C. Neutralize free radicals
- D. Increase blood sugar
Correct answer: C
Rationale: The primary function of antioxidants in the diet is to neutralize free radicals. Free radicals can cause cellular damage, leading to various chronic diseases. Antioxidants help combat this oxidative stress by neutralizing free radicals. Choices A, B, and D are incorrect because antioxidants do not provide energy, support muscle growth, or increase blood sugar; their main role is in combating oxidative stress.
5. Each statement is true of swallowing and processing food, except one. Which is the exception?
- A. The swallowing reflex moves a bolus into the esophagus
- B. A bolus is a mass of food
- C. The bolus is transported to the stomach by osmosis and gravity
- D. The bolus penetrates the diaphragm through the esophageal hiatus
Correct answer: C
Rationale: The correct answer is C. The bolus is not transported to the stomach by osmosis and gravity, but by peristalsis. Peristalsis is the involuntary constriction and relaxation of muscles to push the bolus through the digestive system. Choices A, B, and D are correct statements. A bolus is indeed a mass of food, the swallowing reflex does move the bolus into the esophagus, and the bolus does not penetrate the diaphragm through the esophageal hiatus; instead, it enters the stomach through the lower esophageal sphincter.
