Nursing Elites

1. Which bioterrorism agent is at high risk for use as a potential biological weapon that is readily transmitted by several portals of entry?

• A. anthrax
• B. smallpox
• C. botulism
• D. tularemia

Correct answer: A

Rationale: Anthrax is the correct answer. Anthrax spores can be transmitted through inhalation, ingestion, or skin contact, making it a high-risk agent for bioterrorism. Smallpox, botulism, and tularemia are also potential bioterrorism agents, but they do not have the same versatility in terms of multiple portals of entry, unlike anthrax.

2. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy. Which finding indicates that the therapy is effective?

• A. The client is able to expectorate secretions easily.
• B. The client's oxygen saturation is 92%.
• C. The client's respiratory rate is 20 breaths per minute.
• D. The client's arterial blood gases show a pH of 7.35.

Correct answer: C

Rationale: In a client with COPD receiving oxygen therapy, an effective response is indicated by a respiratory rate of 20 breaths per minute. This suggests that the client is effectively oxygenating while maintaining an appropriate respiratory rate. Choices A, B, and D are incorrect because expectorating secretions easily, having an oxygen saturation of 92%, and arterial blood gases showing a pH of 7.35 are not specific indicators of the effectiveness of oxygen therapy in COPD. Oxygen saturation of 92% may still be suboptimal in COPD, and arterial blood gases showing a pH of 7.35 may not necessarily reflect the overall effectiveness of oxygen therapy.

3. The healthcare provider is caring for a client with a chest tube. Which observation indicates that the chest tube is functioning effectively?

• A. Continuous bubbling in the water-seal chamber.
• B. Intermittent bubbling in the suction control chamber.
• C. No fluctuation (tidaling) in the water-seal chamber.
• D. Drainage of clear, pale yellow fluid from the chest tube.

Correct answer: B

Rationale: Intermittent bubbling in the suction control chamber is the correct observation indicating effective functioning of the chest tube. This bubbling signifies that the suction system is working correctly and maintaining the desired negative pressure in the pleural space. Continuous bubbling in the water-seal chamber suggests an air leak, which is not a normal finding. No fluctuation (tidaling) in the water-seal chamber may indicate a blockage or lack of communication between the pleural space and the water-seal, which is not ideal. Drainage of clear, pale yellow fluid from the chest tube is a normal finding, but it does not specifically indicate the effectiveness of the chest tube function.

4. The nurse is documenting the medical history of a young adult who was recently diagnosed with type 1 diabetes mellitus. The client smokes 2 packs of cigarettes a day, and his father died of a heart attack at the age of 45. Which annual screening is most important for the nurse to include?

• A. peripheral neuropathy
• B. renal insufficiency
• C. retinopathy
• D. hyperlipidemia

Correct answer: D

Rationale: The most important annual screening for the nurse to include is hyperlipidemia. Given the client's smoking history, family history of premature heart disease, and the increased risk of cardiovascular complications associated with diabetes, screening for hyperlipidemia is crucial. This screening is essential in assessing the client's risk of developing cardiovascular disease, which is a significant concern in this case. Peripheral neuropathy (choice A) is a common long-term complication of diabetes but may not be the most immediate concern in this scenario. Renal insufficiency (choice B) is also a complication of diabetes, but given the client's high cardiovascular risk, hyperlipidemia screening takes priority. Retinopathy (choice C) is an important complication of diabetes affecting the eyes, but in this case, focusing on cardiovascular risk assessment through hyperlipidemia screening is more critical.

5. 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.
