What is the most common cause of injury from a house fire?
- A. Explosion
- B. Falls from second-story windows
- C. Thermal damage to skin and body surfaces
- D. Inhalation injury
Correct Answer: D
Rationale: Inhalation injury is the most common cause of injury from a house fire. When a fire occurs, the smoke produced contains harmful gases and particles that can be inhaled, leading to serious respiratory issues. This makes inhalation injury the primary concern during a house fire. Choices A, B, and C are less likely to be the primary cause of injury. While explosions may occur in some cases, inhalation of smoke and toxic fumes is generally the most prevalent danger. Falls from windows and thermal damage to the skin are also significant risks but typically occur after inhalation injuries in the sequence of events during a house fire.

At what point in the nurse-client relationship should termination first be addressed?
- A. in the working phase
- B. in the termination phase
- C. in the orientation phase
- D. when the client initially brings up the topic
Correct Answer: C
Rationale: Termination in the nurse-client relationship should first be addressed in the orientation phase. This is because the client has a right to know the parameters of the relationship from the beginning. During the orientation phase, it is important to discuss if the relationship is time-limited, inform the client about the number of sessions, or explain that it is open-ended with the termination date to be negotiated later. Addressing termination in the orientation phase helps establish transparency and clear communication. Choices A, B, and D are incorrect because termination discussions should ideally start at the beginning of the relationship to set appropriate expectations.
When a client is having a seizure and their blood oxygen saturation drops from 92% to 82%, what should the nurse do first?
- A. Open the airway.
- B. Administer oxygen.
- C. Suction the client.
- D. Check for breathing.
Correct Answer: A
Rationale: When a client is experiencing a seizure and their blood oxygen saturation drops, the priority action for the nurse is to open the airway. Ensuring a clear airway is essential to maintain oxygenation during a seizure episode. Administering oxygen may be necessary but is secondary to ensuring a patent airway. Suctioning the client should only be done if there is an airway obstruction. Checking for breathing is important, but opening the airway takes precedence to support ventilation and oxygenation.
Which of the following neurological disorders is characterized by writhing, twisting movements of the face and limbs?
- A. epilepsy
- B. Parkinson's
- C. multiple sclerosis
- D. Huntington's chorea
Correct Answer: D
Rationale: Huntington's chorea is a neurological disorder characterized by writhing, twisting movements of the face and limbs, known as chorea. Epilepsy is characterized by seizures, not writhing, twisting movements. Parkinson's disease presents with tremors, rigidity, and bradykinesia, not writhing, twisting movements. Multiple sclerosis affects the central nervous system but does not typically involve writhing, twisting movements. Therefore, the correct answer is Huntington's chorea as it specifically manifests with these characteristic movements.
Which is the proper hand position for performing chest vibration?
- A. cup the hands
- B. use the side of the hands
- C. flatten the hands
- D. spread the fingers of both hands
Correct Answer: C
Rationale: The correct hand position for performing chest vibration is to flatten the hands. By flattening the hands over the area of the body where chest percussion is applied, vibrations can be conducted effectively to the chest to help loosen secretions. Cupping the hands may dampen vibrations, using the side of the hands reduces the surface area in contact with the chest, and spreading the fingers can lead to uneven pressure distribution. Therefore, flattening the hands provides the necessary contact and surface area to perform chest vibration efficiently.
In an emergency situation, the nurse determines whether a client has an airway obstruction. Which of the following does the nurse assess?
- A. ability to speak
- B. ability to hear
- C. oxygen saturation
- D. adventitious breath sounds
Correct Answer: A
Rationale: In an emergency situation to assess for airway obstruction, the nurse should prioritize assessing the client's ability to speak. If a client can speak, it indicates that the airway is patent and not completely obstructed, allowing air to pass through the vocal cords for speech production. Choices B, C, and D are not the primary assessments for determining airway obstruction. Assessing the ability to hear is not directly related to an airway obstruction. While oxygen saturation and adventitious breath sounds are important in respiratory assessments, they are not the initial indicators of an airway obstruction. Oxygen saturation reflects the amount of oxygen in the blood, and adventitious breath sounds refer to abnormal lung sounds that may indicate conditions like pneumonia or bronchitis, but they do not specifically confirm airway patency.
