1. Cyanocobalamin is a form of which vitamin?

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B3
• D. Vitamin B12

Correct answer: D

Rationale: Cyanocobalamin is a synthetic form of Vitamin B12. Vitamin B12 is essential for various bodily functions, including red blood cell formation, neurological function, and DNA synthesis. It is not to be confused with Vitamin B1, B2, or B3, which are separate vitamins with different roles in the body.

2. Which biomolecule is responsible for the storage and transfer of genetic information?

• A. Carbohydrates
• B. Proteins
• C. Lipids
• D. Nucleic acids

Correct answer: D

Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.

3. A healthcare professional has just inserted an NG tube for a client who is to start enteral tube feedings. Which of the following actions should the healthcare professional take to verify tube placement?

• A. Measure the tube length.
• B. Obtain an abdominal x-ray.
• C. Flush the tube with 20 mL of water.
• D. Auscultate the client’s lungs.

Correct answer: B

Rationale: Obtaining an abdominal x-ray is the most accurate method to verify the correct placement of an NG tube. Measuring the tube length is not a reliable method to confirm placement as it may vary among individuals. Flushing the tube with water and auscultating the client's lungs are not definitive methods to ensure proper NG tube placement.

4. What is the name of the record that shows all medications and treatments provided on a repeated basis?

• A. Nursing Health History and Assessment Worksheet
• B. Discharge Summary
• C. Nursing Kardex
• D. Medicine and Treatment Record

Correct answer: D

Rationale: The 'Medicine and Treatment Record' is the document that maintains a comprehensive log of all medications and treatments provided on a routine basis. It does not refer to the 'Discharge Summary', which is a clinical report prepared by healthcare professionals at the end of a hospital stay or series of treatments. The 'Nursing Health History and Assessment Worksheet' is used to gather comprehensive data about the patient's health history and current health status, but it does not record ongoing treatment details. The 'Nursing Kardex' is a patient care information system used to quickly communicate patient needs, but it does not consistently record all medications and treatments provided.

5. Inadequate intake of vitamin A occurs in lower socioeconomic groups due to a lack of resources to purchase and consume vegetables and fruits.

• A. Both the statement and the reason are correct and related.
• B. Both the statement and the reason are correct but are not related.
• C. The statement is correct, but the reason is not correct.
• D. The statement is not correct, but the reason is correct.

Correct answer: A

Rationale: Both the statement and the reason are correct and related. Inadequate intake of vitamin A in lower socioeconomic groups is due to a lack of resources to purchase and consume vegetables and fruits. This is supported by the fact that the average intake in the United States meets the Recommended Dietary Allowance (RDA) for vitamin A intake, except in lower socioeconomic groups. These individuals often lack the financial means to buy, prepare, and eat a variety of fruits and vegetables, leading to deficiencies. It's important to note that because vitamin A can be stored in the liver, most adults have sufficient quantities to maintain health. Choices B, C, and D are incorrect because the statement and reason are both accurate and logically connected, as the lack of resources directly impacts the ability to obtain necessary sources of vitamin A.
