1. Any disease that produces ____ malabsorption can bring about deficiencies of vitamins A, D, E, and K.
- A. water
- B. protein
- C. fat
- D. carbs
Correct answer: C
Rationale: Vitamins A, D, E, and K are fat-soluble, meaning they require fat for absorption. Diseases that cause fat malabsorption can lead to deficiencies in these vitamins.
2. In the hospital, when you need the medical record of a discharged patient for research you will request permission through:
- A. Doctor in charge
- B. The hospital director
- C. The nursing service
- D. Medical records section
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 type of fatty acid has carbon atoms connected by two or more double bonds?
- A. Saturated fatty acids
- B. Monounsaturated fatty acids
- C. Trans fatty acids
- D. Polyunsaturated fatty acids
Correct answer: D. Polyunsaturated fatty acids
Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.
4. 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: True
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.
5. You will do nasopharyngeal suctioning on Mr. Abad. Your guide for the length of insertion of the tubing for an adult would be:
- A. tip of the nose to the base of the neck
- B. the distance from the tip of the nose to the middle of the neck
- C. the distance from the tip of the nose to the tip of the ear lobe
- D. eight to ten inches
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
