Question 1 of 9
When planning the response to the potential use of smallpox as an agent of terrorism, the emergency department (ED) nurse manager will plan to obtain adequate quantities of:
Correct Answer: A
Rationale: The correct answer is A: Vaccine. Smallpox is a contagious and potentially deadly disease caused by the variola virus. The smallpox vaccine is the most effective way to prevent and control the spread of smallpox. By obtaining adequate quantities of the smallpox vaccine, the ED nurse manager can protect healthcare workers and the public from contracting the virus in case of a smallpox bioterrorism event. Atropine (B) is used to treat certain types of nerve agent poisoning, not smallpox. Antibiotics (C) are ineffective against viruses like smallpox. Whole blood (D) is not specifically needed for smallpox treatment.
Question 2 of 9
Continuous venovenous hemodialysis is used to
Correct Answer: D
Rationale: The correct answer is D because continuous venovenous hemodialysis combines ultrafiltration, convection, and dialysis techniques. Ultrafiltration removes excess fluid, convection helps in removing solutes, and dialysis involves the diffusion of solutes across a semipermeable membrane. This comprehensive approach ensures effective removal of both fluid and solutes in critically ill patients. Incorrect Answer Analysis: A: Removing fluids and solutes through convection alone is not the complete process in continuous venovenous hemodialysis. B: While volume overload is addressed, continuous venovenous hemodialysis involves more than just removing plasma water. C: Adding dialysate is not the primary method in continuous venovenous hemodialysis; it involves ultrafiltration, convection, and dialysis techniques.

Question 4 of 9
A patient who is undergoing withdrawal of mechanical ventilation appears anxious and agitated. The patient is on a continuous morphine infusion and has an additional order for lorazepam 1 to 2 mg IV as needed (prn). The patient has received no lorazepam during this course of illness. What is the most appropriate nursing intearbvirbe.ncotmio/tnes tt o control agitation?
Correct Answer: B
Rationale: Step-by-step rationale for why choice B is correct: 1. Midazolam is a benzodiazepine used for sedation and anxiolysis. 2. It acts quickly and has a short duration of action, suitable for acute agitation. 3. Lorazepam (also a benzodiazepine) is in the same drug class, ensuring compatibility. 4. Lorazepam is specifically ordered for this patient, indicating its appropriateness. 5. Administering midazolam addresses the patient's agitation efficiently and safely. Summary of why other choices are incorrect: A: Fentanyl is an opioid analgesic, not ideal for managing agitation. C: Increasing morphine infusion can exacerbate sedation or respiratory depression. D: Paralytic agents are used for neuromuscular blockade, not agitation control.
Question 5 of 9
A physician visits a patient in the ICU while the nurse is out. The patient complains that the pain medication is not effective and that he would like to receive an increased dose. The physician has the nurse paged and consults with him in the hallway regarding the patients request for stronger pain medication. The nurse explains that patient was started on a morphine drip only 20 minutes ago and that the drug has not had time to take effectyet. The physician agrees and tells the patient to give it just a bit more time. Which component of a healthy work environment is most evident in this scenario?
Correct Answer: C
Rationale: The correct answer is C: True collaboration. In this scenario, the physician consults with the nurse to understand the situation and collaborates on the best course of action for the patient's care. This demonstrates effective teamwork, communication, and mutual respect between healthcare professionals, which are key components of a healthy work environment. Choice A (Skilled communication) is not the best answer because while communication between the physician and nurse is important, the focus in this scenario is more on collaboration and teamwork. Choice B (Appropriate staffing) is not the best answer as the scenario does not specifically address staffing levels but rather the interaction and collaboration between the physician and nurse. Choice D (Recognizing signs of imminent stroke and paging the physician) is incorrect as it is unrelated to the scenario described, which is about the physician and nurse collaborating on patient care.
Question 6 of 9
When assessing the patient for hypoxemia, the nurse recognizes what as an early sign of the effect of hypoxemia on the cardiovascular system?
Correct Answer: C
Rationale: The correct answer is C: Tachycardia. Hypoxemia results in decreased oxygen levels in the blood, stimulating the body to increase heart rate to improve oxygen delivery. Tachycardia is an early sign of the cardiovascular system compensating for hypoxemia. Heart block (A) is a disruption in the electrical conduction within the heart and is not directly related to hypoxemia. Restlessness (B) is a non-specific sign and can be caused by various factors. Tachypnea (D) is an increased respiratory rate, which is a response to hypoxemia but not a direct effect on the cardiovascular system.
Question 7 of 9
Which statement about family assessment is false?
Correct Answer: A
Rationale: The correct answer is A because assessing the structure of the family (who comprises the family) is not the last step in family assessment. The rationale is that understanding the family structure is essential at the beginning of the assessment process to identify key relationships and support systems. Assessing interaction among family members helps to understand dynamics and relationships within the family. Assessing communication is crucial to identify roles and patterns of interaction. Ongoing assessment is necessary as family dynamics can evolve throughout the illness. Therefore, A is false as family structure assessment is an important initial step, not the last step.
Question 8 of 9
The nurse is developing a teaching plan for an adolescent with a Milwaukee brace. Which instruction should the nurse include?
Correct Answer: A
Rationale: The correct answer is A because wearing the Milwaukee brace over a T-shirt ensures proper skin protection and ventilation. This helps prevent skin irritation and allows for comfortable wearing for long periods. Choice B may cause skin issues due to friction. Choice C is incorrect as moisture from showering can lead to skin problems. Choice D is incorrect as consistent wear is crucial for brace effectiveness.
Question 9 of 9
A nurse decides to seek certification in critical care nursing. What is the most important benefit for the individual nurse in becoming certified in a specialty?
Correct Answer: C
Rationale: The correct answer is C because obtaining certification in critical care nursing demonstrates the nurse's personal expertise in the specialty. Certification confirms the nurse's advanced knowledge and skills, enhancing professional credibility and potential for career advancement. This choice focuses on the individual nurse's competency and dedication to the specialty. Incorrect choices: A: Salary increase is not the primary benefit of certification, although it may be a potential outcome. B: Certification is often preferred but not always required to work in critical care. D: Employers may encourage certification, but it is not always mandated.
