Nursing Elites

1. What describes a criterion used to diagnose diabetes?

• A. a plasma glucose concentration of 100 mg/dL or higher after a fast of at least 12 hours
• B. a casual blood sample of 200 mg/dL or higher in a person with classic symptoms
• C. a plasma glucose concentration measured two hours after a 200-gram glucose load is 400 mg/dL or higher
• D. a HbA1C higher than 5 percent

Correct answer: B

Rationale: A casual blood sample of 200 mg/dL or higher in a person with classic symptoms is a diagnostic criterion for diabetes. This choice aligns with the typical clinical presentation of diabetes and is a key diagnostic indicator. Choices A, C, and D do not accurately reflect the established criteria for diagnosing diabetes, making them incorrect. Choice A pertains to a fasting plasma glucose level, Choice C involves a glucose challenge test, and Choice D refers to HbA1C levels, which are used for monitoring blood sugar control over time, not for diagnosing diabetes.

2. What physiologic role does calcium play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance.

Correct answer: A

Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.

3. A client needs to increase his protein intake and enjoys certain foods. Which of the following foods should the nurse recommend as the best source of protein among these suggestions?

• A. Yams
• B. Eggs
• C. Chicken
• D. Peanuts

Correct answer: C

Rationale: Chicken is the best source of protein among the options provided. It is a lean source of protein and contains essential amino acids needed for the body. Eggs are also a good source of protein, but chicken typically contains more protein per serving compared to eggs. Peanuts are a good source of plant-based protein, but chicken provides a higher amount of protein and is usually leaner. Yams, while nutritious, are not a significant source of protein compared to chicken, eggs, or peanuts.

4. You will give health instructions to Carlo, a case of bronchial asthma. The health instruction will include the following, EXCEPT:

• A. Avoid emotional stress and extreme temperature
• B. Avoid pollution like smoking
• C. Avoid pollens, dust, seafood
• D. Practice respiratory isolation

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.

5. What is the main function of dietary fiber in managing cholesterol levels?

• A. To reduce absorption of dietary fats
• B. To increase cholesterol synthesis
• C. To enhance protein digestion
• D. To decrease cholesterol absorption

Correct answer: D

Rationale: Dietary fiber helps lower cholesterol levels by binding to bile acids and reducing cholesterol absorption.
