The healthcare provider is preparing to administer an intravenous antibiotic to a client with a central venous catheter. Which action is most important?
- A. Flush the catheter with heparin.
- B. Change the dressing at the insertion site.
- C. Check for blood return before administering the antibiotic.
- D. Use sterile technique when accessing the catheter.
Correct Answer: D
Rationale: Using sterile technique when accessing the catheter is crucial to prevent infection in clients with a central venous catheter. This action helps maintain asepsis and reduces the risk of introducing pathogens into the catheter system. Flushing the catheter with heparin helps prevent occlusion but is not as crucial as ensuring sterile technique. Changing the dressing at the insertion site is important for assessing the site's condition but does not directly impact the administration of the antibiotic. Checking for blood return is essential to ensure proper catheter function, but sterile technique takes precedence to prevent infections.

A client with a history of alcohol abuse is admitted with acute pancreatitis. Which assessment finding requires immediate intervention?
- A. Amylase of 120 U/L.
- B. Lipase of 150 U/L.
- C. Calcium of 8.5 mg/dL.
- D. Temperature of 101°F (38.3°C).
Correct Answer: D
Rationale: In a client with acute pancreatitis and a history of alcohol abuse, a temperature of 101°F (38.3°C) can indicate infection, which is a serious complication requiring immediate intervention. Elevated amylase and lipase levels are common in acute pancreatitis but do not directly indicate the need for urgent intervention. A calcium level of 8.5 mg/dL is within the normal range and does not require immediate action in this context.
The healthcare provider is inspecting the external eye structures of a client. Which finding is a normal racial variation?
- A. Blue sclerae.
- B. Brown macules on the sclerae.
- C. Slightly yellow sclerae in an African-American client.
- D. Conjunctival pallor.
Correct Answer: C
Rationale: The slightly yellow color of the sclera is a normal racial variation found in the African-American population. Blue sclerae (Choice A) are associated with osteogenesis imperfecta, not a normal racial variation. Brown macules on the sclerae (Choice B) may indicate issues like melanoma or melanosis but are not a normal racial variation. Conjunctival pallor (Choice D) suggests anemia or decreased blood flow but is not a normal racial variation.
The nurse is planning a health education program for 10-year-olds. Which setting is most likely to increase the preadolescents' participation in the program?
- A. the school classroom
- B. community center
- C. home of one of the children
- D. a local place of worship
Correct Answer: A
Rationale: The school classroom is the most suitable setting to increase preadolescents' participation in a health education program. At the age of 10, children are accustomed to the school environment, making it familiar and comfortable for them. This familiarity can help reduce anxiety and increase engagement during the program. Community centers may be less familiar and could pose distractions, potentially reducing participation. Conducting the program at the home of one of the children may lead to unequal access for other participants and may not provide the necessary facilities for an educational session. A local place of worship may not be perceived as a neutral or suitable environment for a health education program, potentially hindering participation.
The healthcare provider is assessing a client who has returned from surgery. Which finding requires immediate intervention?
- A. Heart rate of 90 beats per minute.
- B. Oxygen saturation of 92%.
- C. Temperature of 99°F (37.2°C).
- D. Pain at the surgical site.
Correct Answer: C
Rationale: A temperature of 99°F (37.2°C) in a postoperative client requires immediate intervention as it may indicate the presence of infection. Elevated temperature post-surgery can be a sign of surgical site infection or systemic infection, which can lead to serious complications if not addressed promptly. Monitoring and managing a fever in a postoperative client is crucial to prevent further complications. The other findings, such as a heart rate of 90 beats per minute, oxygen saturation of 92%, and pain at the surgical site, are common postoperative assessments that may not necessarily require immediate intervention unless they are significantly out of normal range or causing severe distress to the client.
A client with a history of coronary artery disease is admitted with chest pain. Which assessment finding requires immediate intervention?
- A. Heart rate of 90 beats per minute.
- B. Respiratory rate of 20 breaths per minute.
- C. Blood pressure of 130/80 mm Hg.
- D. Chest pain radiating to the left arm.
Correct Answer: D
Rationale: Chest pain radiating to the left arm is a classic symptom of a myocardial infarction (heart attack) in individuals with coronary artery disease. This finding indicates that the heart muscle may not be receiving adequate oxygen, which requires immediate intervention to prevent further damage or complications. The other assessment findings (heart rate of 90 beats per minute, respiratory rate of 20 breaths per minute, blood pressure of 130/80 mm Hg) are within normal limits and do not suggest an acute, life-threatening condition like myocardial infarction.
