1. What is the best dietary advice for a patient with iron-deficiency anemia?
- A. Increase dairy consumption
- B. Increase vitamin C intake
- C. Reduce red meat consumption
- D. Increase fiber intake
Correct answer: B
Rationale: The best dietary advice for a patient with iron-deficiency anemia is to increase vitamin C intake. Vitamin C enhances the absorption of non-heme iron, which can help improve iron-deficiency anemia. Choices A, C, and D are not the best options for this condition. Increasing dairy consumption (Choice A) may not directly address the iron deficiency. Reducing red meat consumption (Choice C) may limit heme iron intake, which is easily absorbed by the body. Increasing fiber intake (Choice D) is generally beneficial but is not specifically recommended as the top advice for iron-deficiency anemia.
2. What should Mrs. Smith do to increase her HDL levels, as advised by the nurse?
- A. Monitor her blood glucose levels
- B. Quit smoking
- C. Control her blood pressure
- D. Take fish oil supplements
Correct answer: B: Quit smoking
Rationale: The correct answer is 'Quit smoking.' Smoking has been shown to lower HDL (High-Density Lipoprotein) levels, and quitting can help to improve these levels. HDL is often referred to as 'good cholesterol' because it helps to remove other forms of cholesterol from the bloodstream, reducing the risk of heart disease. While monitoring blood glucose levels, controlling blood pressure, and taking fish oil supplements can contribute to overall health and wellbeing, they do not directly increase HDL levels in the same way that quitting smoking does. Therefore, quitting smoking is the most effective way for Mrs. Smith to increase her HDL levels as advised by the nurse.
3. Which of the following terms describes the amount of blood ejected per heartbeat?
- A. Stroke volume
- B. Cardiac output
- C. Ejection fraction
- D. Afterload
Correct answer: A
Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.
4. Which test is used to monitor the degree of blood glucose control over a long period?
- A. Glucose tolerance test
- B. Glycated hemoglobin level
- C. Self-monitoring of blood glucose
- D. 24-hour urinary glucose excretion
Correct answer: B
Rationale: The correct answer is B, glycated hemoglobin level. The glycated hemoglobin (HbA1c) test measures the average blood glucose levels over the past 2-3 months, providing a long-term picture of glucose control. Choice A, the glucose tolerance test, measures how well your body processes glucose but is not specifically for long-term monitoring. Choice C, self-monitoring of blood glucose, involves daily testing by individuals, providing immediate rather than long-term information. Choice D, 24-hour urinary glucose excretion, measures the amount of glucose excreted in the urine over 24 hours and is not typically used for long-term monitoring of blood glucose control.
5. Reducing the amount of trans fat in the diet is an effective method of decreasing the risk of CHD. Which food is most likely a source of trans fat?
- A. hot dogs
- B. whole milk
- C. fatty fish
- D. potato chips
Correct answer: D
Rationale: The correct answer is D: potato chips. Potato chips, especially when fried in hydrogenated oils, are a common source of trans fats, which are linked to an increased risk of coronary heart disease (CHD). Hot dogs (choice A) can also contain trans fats if made with processed meats and added fats. Whole milk (choice B) and fatty fish (choice C) do not typically contain trans fats, making them less likely sources compared to potato chips.
