Which of the following is a proper guideline for hearing aids?
- A. Hearing aids should be left on when not in use.
- B. The batteries last for the life of the hearing aid.
- C. Ensure hearing aids are turned on.
- D. Soaking hearing aids in water makes cleaning easier.
Correct Answer: C
Rationale: The correct answer is C: Ensure hearing aids are turned on. This guideline is crucial as hearing aids need to be powered on to function effectively. Turning them on allows users to benefit from improved hearing. Choice A is incorrect as leaving hearing aids on when not in use drains the battery. Choice B is incorrect as hearing aid batteries need to be replaced regularly. Choice D is incorrect as soaking hearing aids in water can damage them, not make cleaning easier.

The chain of command is
- A. A legal term meaning a person can be held responsible for harming someone else
- B. The person in charge of the department for each shift
- C. The line of authority in a facility
- D. The department that a nursing assistant goes to if he wants to report a problem
Correct Answer: C
Rationale: The correct answer is C because the chain of command refers to the hierarchical structure within an organization that outlines the line of authority and communication. This ensures that decisions and information flow efficiently from top management to frontline employees. Option A is incorrect as it describes legal responsibility. Option B is incorrect as it refers to a shift supervisor, not the entire chain of command. Option D is incorrect as it describes a specific department, not the overall structure of authority. Ultimately, understanding the chain of command is crucial for effective communication and decision-making within an organization.
Motor vehicle crash, GCS 6, dilated pupil, contralateral weakness, next step?
- A. "Obtain a CT-scan of the head"
- B. "Administer decadron 20mg IV"
- C. "Perform endotracheal intubation"
- D. "Administer mannitol 1g/kg IV"
Correct Answer: C
Rationale: The correct next step is to perform endotracheal intubation (Choice C) in this scenario. Given the presentation of a motor vehicle crash with a GCS of 6, dilated pupil, and contralateral weakness, it indicates severe head trauma causing impending airway compromise and the need for airway protection. Intubation will secure the airway, ensure adequate oxygenation, and prevent the risk of aspiration.
Choice A (CT-scan of head) is not the immediate priority as the patient's airway needs to be secured first. Choice B (Decadron) is not indicated for acute head trauma and may even worsen brain injury. Choice D (Mannitol) may help reduce intracranial pressure, but securing the airway takes precedence in this critical situation.
Making an area or object free of all microorganisms is called
- A. Infection prevention
- B. Disinfection
- C. Transmission
- D. Surgical asepsis
Correct Answer: D
Rationale: The correct answer is D: Surgical asepsis. Surgical asepsis refers to the practice of creating and maintaining a sterile environment to eliminate all microorganisms. This is crucial in surgical procedures to prevent infections. Infection prevention (choice A) focuses on strategies to reduce the risk of infections but does not necessarily involve complete elimination of microorganisms. Disinfection (choice B) involves killing or inactivating most disease-causing microorganisms, but it does not guarantee complete elimination. Transmission (choice C) refers to the spread of microorganisms from one person to another, which is different from making an area or object completely free of microorganisms.
You are cleaning the back of the truck after transporting a trauma patient to the emergency department. Which of the following contaminated items should not be placed in a plastic biohazard bag?
- A. Plastic IV catheter
- B. Nasopharyngeal or oral airway
- C. French suction catheter
- D. Blood-soaked gauze pads
Correct Answer: A
Rationale: The correct answer is A: Plastic IV catheter. The reason is that plastic IV catheters are considered sharp objects and should not be placed in a plastic biohazard bag to prevent accidental needle-stick injuries. Instead, they should be disposed of in a designated sharps container. Nasopharyngeal or oral airway, French suction catheter, and blood-soaked gauze pads can be placed in a plastic biohazard bag as they do not pose the same risk of needle-stick injuries.
