1. The healthcare provider is preparing to administer phytonadione to a newborn. Which statement made by the parents indicates understanding why the healthcare provider is administering this medication?
- A. Prevent hemorrhagic disorders.
- B. Help an immature liver.
- C. Improve insufficient dietary intake.
- D. Stimulate the immune system.
Correct answer: A
Rationale: The correct answer is A: 'Prevent hemorrhagic disorders.' Phytonadione (vitamin K) is administered to newborns to prevent hemorrhagic disease by promoting blood clotting. Newborns are born with low levels of vitamin K, which is essential for blood clotting, hence the administration to prevent hemorrhagic disorders. Choice B is incorrect because phytonadione is not given to help an immature liver but to supply vitamin K. Choice C is incorrect as phytonadione is not administered to improve dietary intake but to provide essential vitamin K. Choice D is incorrect as phytonadione does not stimulate the immune system but helps with blood clotting.
2. A school nurse is planning a program to address bullying among students. Which strategy is most likely to be effective?
- A. Implementing a zero-tolerance policy for bullying
- B. Conducting peer mediation sessions
- C. Providing workshops on conflict resolution
- D. Promoting bystander intervention
Correct answer: D
Rationale: Promoting bystander intervention is the most effective strategy as it empowers students to take action and prevent bullying incidents. By encouraging bystanders to intervene when they witness bullying, the behavior is less likely to continue. Zero-tolerance policies may have limited effectiveness as they often focus on punishment rather than prevention. Peer mediation and conflict resolution workshops are valuable but may not directly address the immediate need for bystander intervention in bullying situations.
3. A client with cirrhosis is admitted with hepatic encephalopathy. Which clinical finding is most concerning?
- A. Confusion and altered mental status
- B. Increased abdominal girth
- C. Yellowing of the skin
- D. Peripheral edema
Correct answer: A
Rationale: Confusion and altered mental status are the most concerning clinical findings in a client with hepatic encephalopathy. These symptoms indicate worsening liver function and potential neurological complications, requiring immediate medical attention. Increased abdominal girth may suggest ascites, yellowing of the skin can indicate jaundice, and peripheral edema may be related to fluid retention, but in the context of hepatic encephalopathy, confusion and altered mental status take precedence due to the risk of rapid deterioration and the need for prompt management.
4. Which of the following makes it possible to predict the genotype and phenotype of the offspring of sexual reproduction?
- A. Punnett square
- B. Chi-square
- C. Microscope
- D. None of these
Correct answer: A
Rationale: The correct answer is A, Punnett square. A Punnett square is a tool specifically designed to predict the genotype and phenotype combinations of offspring resulting from a particular cross or breeding experiment. It helps in understanding the probability of different genotypes and phenotypes appearing in the offspring. Choice B, Chi-square, is a statistical test used to determine if there is a significant difference between the expected frequencies and the observed frequencies in a study. Choice C, Microscope, is used for viewing tiny structures and organisms, not for predicting genetic outcomes. Choice D, None of these, is incorrect as Punnett square is a valid tool for predicting genetic outcomes in offspring.
5. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute by nasal cannula. The client develops respiratory distress and the nurse increases the oxygen to 4 liters per minute. Shortly afterward, the client becomes lethargic and confused. What action should the nurse take first?
- A. Reposition the nasal cannula
- B. Lower the oxygen rate
- C. Encourage the client to cough and deep breathe
- D. Monitor the client's oxygen saturation level
Correct answer: B
Rationale: In this scenario, the client with COPD receiving increased oxygen is experiencing oxygen toxicity, leading to lethargy and confusion. Lowering the oxygen rate is the priority action to prevent further harm. Repositioning the nasal cannula, encouraging coughing and deep breathing, and monitoring oxygen saturation are all important interventions, but the immediate concern is to address the oxygen toxicity by lowering the oxygen rate.
