1. Scurvy is caused by a deficiency of ascorbic acid (Vitamin C) because ascorbic acid is required for collagen synthesis. Is this statement true or false?

• A. TRUE
• B. FALSE
• C. Not applicable
• D. Not applicable

Correct answer: A

Rationale: The statement is accurate. Scurvy is indeed caused by a deficiency in ascorbic acid, which is another name for Vitamin C. This vitamin plays a crucial role in the synthesis of collagen, a protein that helps in the formation and strength of skin, blood vessels, tissues, and bones. When the body lacks Vitamin C, it cannot produce enough collagen, leading to symptoms associated with scurvy such as bleeding gums and weakened immunity. The choice 'False' is incorrect because it contradicts the proven medical and scientific understanding of the causes of scurvy. Choices 'C' and 'D' are marked as 'Not applicable' because the question only requires a true or false answer.

2. 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.

3. Which of the following is a good food source of iodine?

• A. Seafood
• B. Lettuce
• C. Broccoli
• D. Pork

Correct answer: A

Rationale: Seafood is a rich source of iodine, essential for maintaining healthy thyroid function and overall metabolic health. While lettuce, broccoli, and pork may contain some iodine, they do not provide as substantial an amount as seafood. Therefore, they are not considered 'good' sources of iodine in comparison.

4. Before the nurse researcher starts her study, she analyzes how much time, money, materials and people she will need to complete the research project. This analysis prior to beginning the study is called:

• A. Validity
• B. Feasibility
• C. Reliability
• D. Researchability

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

5. Which of the following statements are correct?

• A. Lipids are transported in the blood as lipoproteins, which are clusters of lipids associated with proteins.
• B. In type II diabetes, the pancreas produces insulin, but cells are resistant to this signal.
• C. The glycemic index classifies foods based on their potential to raise blood glucose levels.
• D. All of the above

Correct answer: D

Rationale: Option A is correct because lipoproteins indeed transport lipids in the blood. They are complexes of lipids and proteins that transport water-insoluble lipids through the blood. Option B is correct as it accurately describes the condition of type II diabetes where the pancreas can produce insulin, but the cells are resistant to its signal, causing an ineffective regulation of blood sugar. Option C is also correct because the glycemic index is indeed a classification system for foods based on their potential to raise blood glucose levels. High glycemic index foods raise blood glucose levels faster than low glycemic index foods. Hence, all the statements are correct, making option D the correct answer.
