1. Which vitamin is also known as Niacin?
- A. Vitamin B1
- B. Vitamin B2
- C. Vitamin B3
- D. Vitamin B12
Correct answer: C
Rationale: The correct answer is Vitamin B3, also known as Niacin. Niacin is essential for energy metabolism and can help improve cholesterol levels. Vitamin B1 is Thiamine, Vitamin B2 is Riboflavin, and Vitamin B12 is Cobalamin. These vitamins have different functions in the body and are not synonymous with Niacin.
2. What is the rationale in the use of bag technique during home visits?
- A. It helps render effective nursing care to clients or other members of the family
- B. It saves time and effort of the nurse in the performance of nursing procedures
- C. It should minimize or prevent the spread of infection from individuals to families
- D. It should not overshadow concerns for the patient
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.
3. 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.
4. A caregiver is teaching a parent about recommended protein intake for a toddler. Which of the following food selections is equivalent to 1 oz of protein?
- A. 2 tbsp peanut butter
- B. ½ cup peas
- C. 1 slice of bread
- D. 1 scrambled egg
Correct answer: D
Rationale: One scrambled egg is equivalent to 1 oz of protein, making it a suitable choice for a toddler's diet. A ½ cup of peas (choice B) does not provide 1 oz of protein but is still a good source of protein. 2 tbsp of peanut butter (choice A) contains more than 1 oz of protein. 1 slice of bread (choice C) typically provides less protein than 1 oz.
5. Each statement is true of water-soluble vitamins, except one. Which is it?
- A. Act as coenzymes
- B. Deficiencies develop rapidly
- C. Daily intake is necessary
- D. Absorbed in the jejunum
Correct answer: B
Rationale: The correct answer is B. Water-soluble vitamins do not develop deficiencies rapidly because the body does not store them for long periods. They must be obtained through food constantly. Choice A is correct because water-soluble vitamins often act as coenzymes in various metabolic reactions. Choice C is correct as daily intake of water-soluble vitamins is necessary since they are not stored in the body. Choice D is incorrect as water-soluble vitamins are absorbed primarily in the small intestine, particularly in the duodenum and ileum, not the jejunum.
