A nurse is preparing to administer ciprofloxacin to a client. The nurse should identify that the medication is treatment for exposure to which of the following agents?
- A. Smallpox
- B. Anthrax
- C. Ebola virus
- D. Sarin gas
Correct Answer: B
Rationale: The correct answer is B: Anthrax. Ciprofloxacin is an antibiotic commonly used to treat anthrax, which is a bacterial infection caused by Bacillus anthracis. The rationale behind this choice is that ciprofloxacin is effective in treating anthrax infections by inhibiting the growth of the bacteria. Smallpox (A), Ebola virus (C), and Sarin gas (D) are not treated with ciprofloxacin as they are caused by a virus, a different virus, and a nerve gas, respectively.

A nurse is working with an interdisciplinary disaster committee to develop a community-wide emergency response plan in the event of a nonbiological or chemical incident. The nurse should include which of the following agencies to be notified immediately after calling 911?
- A. Office of Emergency Management (OEM)
- B. Federal Emergency Management Agency (FEMA)
- C. American Red Cross (ARC)
- D. U.S. Department of Homeland Security (DHS)
Correct Answer: A
Rationale: The correct answer is A: Office of Emergency Management (OEM). The rationale is that the Office of Emergency Management is responsible for coordinating disaster response efforts at the local level. By notifying OEM immediately after calling 911, the nurse ensures a timely and organized response to the incident. The other choices are incorrect because FEMA mainly provides federal assistance for disasters, American Red Cross focuses on providing relief services to disaster victims, and the Department of Homeland Security oversees national security and emergency preparedness but may not be directly involved in local response coordination.
A home health nurse is assessing an older adult client in the home who has decreased vision due to a history of glaucoma. Which of the following findings should the nurse identify as a safety risk?
- A. Handrails are present in the bathroom.
- B. Electrical cords are placed along the walls.
- C. Uses a microwave for cooking.
- D. Scatter rugs are present in the kitchen.
Correct Answer: D
Rationale: The correct answer is D: Scatter rugs are present in the kitchen. Scatter rugs can pose a safety risk for an older adult with decreased vision due to glaucoma as they increase the risk of tripping and falling. The uneven surface and lack of secure placement make scatter rugs hazardous. Handrails in the bathroom (A) enhance safety, electrical cords along the walls (B) may be a tripping hazard but can be easily addressed, and using a microwave for cooking (C) is a safe and convenient option for someone with decreased vision.
A nurse is assessing a client who is receiving metoprolol. Which of the following indicates a therapeutic effect?
- A. Decreased blood pressure.
- B. Decreased dysrhythmias.
- C. Increased urine output.
- D. Decreased pulse.
Correct Answer: A
Rationale: The correct answer is A: Decreased blood pressure. Metoprolol is a beta-blocker that works by reducing heart rate and decreasing the workload on the heart, leading to a decrease in blood pressure. This is a therapeutic effect as it helps manage conditions like hypertension and angina.
Incorrect choices:
B: Decreased dysrhythmias - While metoprolol can help reduce dysrhythmias, the primary therapeutic effect is on blood pressure.
C: Increased urine output - Metoprolol does not directly affect urine output.
D: Decreased pulse - Decreasing pulse is a common side effect of metoprolol, but the therapeutic effect is primarily on blood pressure.
A nurse is caring for four clients who have drainage tubes. Which of the following clients is at risk for hypokalemia?
- A. The client who has a tracheostomy tube attached to humidified oxygen.
- B. The client who has an indwelling urinary catheter to gravity drainage.
- C. The client who has a chest tube to water seal.
- D. The client who has a nasogastric tube to suction.
Correct Answer: D
Rationale: The correct answer is D. The client with a nasogastric tube to suction is at risk for hypokalemia because suctioning can lead to loss of gastric contents, which contain potassium. This can result in decreased potassium levels in the body, leading to hypokalemia.
A: The client with a tracheostomy tube attached to humidified oxygen is not at risk for hypokalemia as oxygen therapy does not directly impact potassium levels.
B: The client with an indwelling urinary catheter to gravity drainage is not at risk for hypokalemia as urinary drainage does not affect potassium levels significantly.
C: The client with a chest tube to water seal is not at risk for hypokalemia as chest tube drainage does not lead to potassium loss.
In summary, choice D is correct because suctioning via a nasogastric tube can cause potassium loss, while choices A, B, and C are incorrect as they do not directly impact potassium levels.
A nurse is caring for a client who has returned from the surgical suite following surgery for a fractured mandible. The client had intermaxillary fixation to repair and stabilize the fracture. Which of the following actions is the priority for the nurse to take?
- A. Promote oral hygiene.
- B. Ensure adequate nutrition.
- C. Prevent aspiration.
- D. Relieve the client’s pain.
Correct Answer: C
Rationale: The correct answer is C: Prevent aspiration. This is the priority because with intermaxillary fixation, the client's ability to swallow and protect their airway is compromised. Aspiration can lead to serious complications such as pneumonia. Promoting oral hygiene (A) can be important but not the priority. Ensuring adequate nutrition (B) is important but can be addressed once the risk of aspiration has been minimized. Relieving pain (D) is also important but not the priority over preventing aspiration in this case.
