1. Which vitamin deficiency is most likely to be associated with increased risk of macular degeneration?
- A. Vitamin A
- B. Vitamin B12
- C. Vitamin C
- D. Vitamin E
Correct answer: D
Rationale: Vitamin E is an antioxidant that helps protect eye health and prevent macular degeneration.
2. In some hip surgeries, an epidural catheter for Fentanyl epidural analgesia is given. What is your nursing priority care in such a case?
- A. Instruct the client to observe strict bed rest
- B. Check for epidural catheter drainage
- C. Administer analgesia through the epidural catheter as prescribed
- D. Assess respiratory rate carefully
Correct answer: D
Rationale: The nursing priority care in a case where an epidural catheter for Fentanyl epidural analgesia is given during hip surgeries is to assess the respiratory rate carefully. Respiratory depression is a potential side effect of Fentanyl, especially when administered epidurally. Monitoring the respiratory rate is crucial to detect any signs of respiratory distress promptly. Instructing the client to observe strict bed rest (Choice A) may be necessary but is not the priority over ensuring respiratory function. Checking for epidural catheter drainage (Choice B) and administering analgesia through the epidural catheter as prescribed (Choice C) are important aspects of care, but ensuring adequate ventilation takes precedence to prevent complications.
3. Before Dianne performs the formal research study, what do you call the pre-testing, small-scale trial run to determine the effectiveness of data collection and methodological problems that might be encountered?
- A. Sampling
- B. Pre-testing
- C. Pre-Study
- D. Pilot Study
Correct answer: D
Rationale: The correct answer is 'Pilot Study.' A pilot study is a small-scale trial run conducted before the formal research study to identify and address any issues related to data collection and methodology. This helps in determining the effectiveness of the research process and identifying potential problems that may arise. Choice A, 'Sampling,' refers to the process of selecting a subset of individuals from a larger population for research. Choice B, 'Pre-testing,' simply involves testing something before the main testing phase. Choice C, 'Pre-Study,' is not a commonly used term in research methodology and does not specifically refer to the small-scale trial run described in the question.
4. Electrolytes create _____, which is caused by water following electrolytes within or between cells.
- A. energy
- B. active transport
- C. passive diffusion
- D. osmotic pressure
Correct answer: D
Rationale: Osmotic pressure is the force that drives water movement across cell membranes due to the presence of electrolytes, helping to balance fluid levels in the body. Choice A, 'energy,' is incorrect as electrolytes do not directly create energy. Choice B, 'active transport,' refers to the movement of molecules across a cell membrane requiring energy, not the movement of water. Choice C, 'passive diffusion,' is the process by which substances move from an area of higher concentration to lower concentration, not related to the movement of water following electrolytes.
5. Which of the following are the primary bacteria involved in the initiation of dental caries?
- A. Streptococcus mutans and Lactobacillus species
- B. Salmonella and Listeria species
- C. Streptococcus, Lactobacillus, and Salmonella species
- D. Listeria, Botulinum species, and Escherichia coli
Correct answer: A
Rationale: The correct answer is A: Streptococcus mutans and Lactobacillus species. These bacteria are primarily responsible for initiating dental caries by fermenting carbohydrates and producing acids that demineralize enamel. Choice B, Salmonella and Listeria species, are not the primary bacteria involved in dental caries. Choice C includes Salmonella which is not a primary culprit in dental caries. Choice D lists Listeria, Botulinum species, and Escherichia coli, none of which are the primary bacteria associated with initiating dental caries.
