1. Which substance would most likely need to be restricted in patients with heart failure who use diuretics to help reduce fluid retention?
- A. potassium
- B. magnesium
- C. sodium
- D. chloride
Correct answer: C
Rationale: Sodium restriction is crucial in heart failure management to prevent fluid retention, which can worsen symptoms of heart failure.
2. Which of the following is the most important risk factor for development of Chronic Obstructive Pulmonary Disease?
- A. Cigarette smoking
- B. Occupational exposure
- C. Air pollution
- D. Genetic abnormalities
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
3. What is the digestive action of bile?
- A. It breaks down carbohydrates
- B. It breaks down proteins
- C. It breaks down lipids
- D. It aids in fat digestion
Correct answer: D
Rationale: Bile, which is produced by the liver and stored in the gallbladder, aids in the digestion of fats. It does this by emulsifying the fats, which makes them easier for the digestive enzymes, such as lipase, to break down. While choices A, B, and C could be seen as partially correct since fats are a type of lipid and the process of breaking down fats could be seen as breaking down lipids, the most accurate answer is D, as the primary function of bile is to aid in fat digestion, not the digestion of all types of lipids or the digestion of proteins or carbohydrates.
4. The nurse understands that malnutrition is a prevalent issue among hospitalized individuals. What is it commonly associated with?
- A. Decreased health care expenses
- B. Elevated blood pressure
- C. Decreased mortality rates
- D. A compromised immune system
Correct answer: D
Rationale: Malnutrition is often associated with a weakened immune system. This is because when the body is not sufficiently nourished, it lacks the necessary nutrients to maintain a well-functioning immune system, making patients more vulnerable to infections and other health complications. This can potentially increase mortality rates and prolong hospital stays, contrary to choice C. Choices A and B are incorrect as malnutrition does not lead to decreased health care costs or high blood pressure. In fact, it may increase health care costs due to the potential for increased complications and extended hospital stays.
5. What is a major feature of the therapeutic lifestyle changes (TLC) recommended for the treatment of high blood cholesterol?
- A. Avoiding all foods that contain cholesterol
- B. Reducing sodium intake to less than 2 g/day
- C. Limiting total fat intake to less than 30% of energy intake
- D. Limiting saturated fat intake to less than 7% of energy intake
Correct answer: D
Rationale: The correct answer is D, 'Limiting saturated fat intake to less than 7% of energy intake.' This is a central feature of the therapeutic lifestyle changes (TLC) recommended for treating high blood cholesterol. Saturated fats can increase low-density lipoprotein (LDL) cholesterol, a significant risk factor for heart disease. Choice A is incorrect because while it is recommended to limit cholesterol intake, it's not suggested to avoid all foods containing cholesterol entirely in the TLC. Choice B is also incorrect as although reducing sodium intake is beneficial for controlling blood pressure, it's not specifically targeted in the TLC for managing high cholesterol. Lastly, while limiting total fat intake is a healthy guideline, it's not as specific or effective as limiting saturated fat intake, making choice C also incorrect.
