Adult Health 1 Final Exam
1. Which intervention is most effective in preventing the spread of infection in a healthcare setting?
- A. Wearing gloves
- B. Using hand sanitizer
- C. Practicing hand hygiene
- D. Disinfecting surfaces
Correct answer: C
Rationale: Practicing hand hygiene is the most effective measure to prevent the spread of infection in healthcare settings. While wearing gloves, using hand sanitizer, and disinfecting surfaces are important infection control measures, they are not as effective as proper hand hygiene. Hand hygiene, including handwashing with soap and water or using alcohol-based hand sanitizers, is crucial in preventing the transmission of pathogens from one person to another, making it the best choice among the options provided. Wearing gloves primarily protects the wearer and is not a substitute for hand hygiene. Using hand sanitizer is helpful but may not be as effective as proper handwashing. Disinfecting surfaces is important but does not address the direct transmission of pathogens through hand contact, which hand hygiene effectively prevents.
2. The client is diagnosed with pneumonia. Which intervention is most effective in promoting airway clearance?
- A. Administer bronchodilators as prescribed
- B. Encourage increased fluid intake
- C. Perform chest physiotherapy
- D. Provide humidified oxygen
Correct answer: B
Rationale: Encouraging increased fluid intake is the most effective intervention in promoting airway clearance for a client with pneumonia. Increasing fluid intake helps to thin respiratory secretions, making it easier for the client to clear the airways. Administering bronchodilators may help with bronchospasm but does not directly promote airway clearance. Chest physiotherapy may be beneficial but is not the first-line intervention for promoting airway clearance in pneumonia. Providing humidified oxygen can improve oxygenation but does not directly address airway clearance.
3. The nurse is caring for a client with cirrhosis of the liver. Which clinical finding is most concerning?
- A. Jaundice.
- B. Ascites.
- C. Spider angiomas.
- D. Asterixis.
Correct answer: D
Rationale: The correct answer is D, Asterixis. Asterixis, also known as liver flap, is a sign of hepatic encephalopathy, a severe complication of liver disease that necessitates immediate attention. While jaundice (choice A), ascites (choice B), and spider angiomas (choice C) are common clinical findings in cirrhosis, asterixis is the most concerning due to its association with hepatic encephalopathy, which can lead to altered mental status and even coma. Jaundice, ascites, and spider angiomas are also important signs in cirrhosis, but asterixis indicates a more critical condition requiring urgent intervention.
4. The nurse is caring for a client with a history of seizure disorder who is receiving phenytoin (Dilantin). Which laboratory value is most important to monitor?
- A. Phenytoin level
- B. Sodium level
- C. Hemoglobin level
- D. White blood cell count
Correct answer: A
Rationale: Corrected Rationale: Monitoring the phenytoin level is crucial to ensure it is within the therapeutic range and to prevent toxicity. Monitoring sodium level is important in clients receiving lithium, not phenytoin. Hemoglobin level and white blood cell count are not directly related to phenytoin therapy monitoring.
5. The healthcare provider plans to assess a newborn and check the infant's Moro reflex. What is the healthcare provider evaluating?
- A. Neurological integrity
- B. Renal functioning
- C. Thermoregulation
- D. Respiratory adequacy
Correct answer: A
Rationale: The Moro reflex is an instinctive response observed in newborns, indicating their neurological integrity. This reflex is evaluated by eliciting a startle response in the infant, involving the sudden extension and abduction of the limbs, followed by their retraction. This assessment helps in determining the proper functioning of the infant's nervous system and brain. Choices B, C, and D are incorrect as they do not relate to the evaluation of the Moro reflex. Renal functioning pertains to kidney function, thermoregulation refers to temperature control, and respiratory adequacy involves assessing breathing and oxygenation levels, none of which are evaluated through the Moro reflex.
