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 seizures is admitted with status epilepticus. Which medication should the nurse prepare to administer?
- A. Phenytoin (Dilantin)
- B. Diazepam (Valium)
- C. Lorazepam (Ativan)
- D. Carbamazepine (Tegretol)
Correct Answer: C
Rationale: In the management of status epilepticus, the initial medication of choice is a benzodiazepine to rapidly terminate the seizure activity. Lorazepam (Ativan) is preferred over Diazepam (Valium) due to its longer duration of action and lower risk of respiratory depression. Phenytoin (Dilantin) and Carbamazepine (Tegretol) are not the first-line agents for the acute treatment of status epilepticus, making them incorrect choices in this scenario.
The healthcare professional is developing a program to educate parents on the importance of immunizations. Which topic should be prioritized?
- A. the benefits of immunizations
- B. the potential side effects of vaccines
- C. the immunization schedule
- D. ways to comfort children during vaccinations
Correct Answer: A
Rationale: Prioritizing the benefits of immunizations is crucial in helping parents comprehend the significance of vaccines in safeguarding their children against preventable diseases. Understanding the positive impact of immunizations can alleviate concerns and misconceptions that parents may have, ultimately encouraging them to make informed decisions regarding their children's health. Discussing potential side effects (choice B) is important but should come after highlighting the benefits to avoid instilling unnecessary fear. While the immunization schedule (choice C) is essential information, it may be overwhelming if presented as the initial focus. Comforting children during vaccinations (choice D) is valuable but secondary to ensuring parents understand the benefits of immunizations.
When planning a community health fair to promote mental health awareness, which activity should be included to best engage participants?
- A. free mental health screenings
- B. lectures on mental health topics
- C. distribution of mental health resources
- D. interactive workshops on stress management
Correct Answer: A
Rationale: The best activity to engage participants in a community health fair promoting mental health awareness is to offer free mental health screenings. This activity not only attracts participants but also provides them with immediate, valuable information about their mental health status. Free screenings can help raise awareness, encourage early detection of mental health issues, and prompt participants to seek further assistance if needed. Lectures, while informative, may not be as engaging or impactful as the personalized feedback individuals receive from screenings. Distributing resources is helpful, but active engagement through screenings is more effective in promoting awareness and encouraging action. Interactive workshops on stress management are beneficial but might not provide the same level of individualized insight into mental health as screenings do.
A community health nurse is conducting a neighborhood discussion group about disaster planning. What information regarding transmission of anthrax should the nurse provide to the group?
- A. Infection is acquired when anthrax spores enter a host.
- B. Mature anthrax bacteria live dormant on inanimate objects.
- C. Spores cannot survive for extended periods outside a living host.
- D. Anthrax is transmitted by respiratory droplets from person to person.
Correct Answer: A
Rationale: The correct answer is A: Infection is acquired when anthrax spores enter a host. Anthrax is primarily transmitted through spores entering the body, either through the skin, inhalation, or ingestion. Person-to-person transmission of anthrax is extremely rare and not a significant mode of transmission. Choices B and C are incorrect because mature anthrax bacteria do not live dormant on inanimate objects, and spores can survive for extended periods outside a living host. Choice D is incorrect as anthrax is not transmitted by respiratory droplets from person to person.
A client with a history of deep vein thrombosis (DVT) is admitted with unilateral leg swelling. Which intervention should the nurse implement?
- A. Elevate the affected leg on a pillow.
- B. Apply a warm compress to the affected leg.
- C. Perform passive range-of-motion exercises on the affected leg.
- D. Encourage the client to ambulate frequently.
Correct Answer: A
Rationale: The correct intervention for a client with a history of deep vein thrombosis (DVT) and unilateral leg swelling is to elevate the affected leg on a pillow. Elevating the affected leg helps reduce swelling and pain by promoting venous return and preventing stasis of blood flow. Applying a warm compress (Choice B) may increase inflammation and worsen the condition. Performing passive range-of-motion exercises (Choice C) and encouraging ambulation (Choice D) can dislodge a clot and lead to potential embolism, making these choices contraindicated in a client with DVT.
