Correct Answer: B

Rationale: The correct action for the emergency triage nurse to take upon receiving the history that a client has a severe cough, fever, night sweats, and body wasting is to seclude the client from other clients and visitors. These symptoms are suggestive of tuberculosis, a highly infectious disease. By secluding the client, the nurse can prevent the potential spread of the infection to others. Donning personal protective equipment, including gown, gloves, and a mask, is crucial when providing care to the client, but the immediate priority is to prevent the spread of infection by isolating the client. Placing the client in isolation until further assessment is completed ensures that the client is kept away from others until a proper diagnosis and treatment plan can be established, reducing the risk of transmission. Performing no intervention until test results confirm a diagnosis is inappropriate as immediate isolation is necessary in suspected cases of highly infectious diseases like tuberculosis.

Correct Answer: B

Rationale: Guillain-Barré syndrome is characterized by a severe complication of respiratory failure due to the involvement of the peripheral nerves that control breathing. While Bell's palsy, trigeminal neuralgia, and tetanus are also conditions affecting peripheral nerves, they do not typically lead to respiratory failure like Guillain-Barré syndrome. Bell's palsy causes facial muscle weakness, trigeminal neuralgia results in severe facial pain, and tetanus leads to muscle stiffness and spasms, but none of these conditions directly involve respiratory failure.

Correct Answer: B

Rationale: An individual may receive medical care without giving informed consent in an emergency, life-or-death situation. This exception allows healthcare providers to provide immediate treatment to save a person's life or prevent serious harm when time is of the essence. Choices A, C, and D are incorrect because in all other situations, informed consent is required. The durable power of attorney for health care should be involved if available, the physician should have a discussion with the client in non-life-threatening situations, and in cases where clients are unable to speak for themselves, their designated representative or responsible party should be involved in the consent process.

Correct Answer: D

Rationale: Hazards of improper splinting can lead to the aggravation of a bone or joint injury, reduced distal circulation, and delay in transporting a client with a life-threatening injury. Choosing 'All of the above' (Option D) is the correct answer as it encompasses all the hazards mentioned. Option A is incorrect because it only addresses one aspect of the hazards. Option B is incorrect as it does not cover all the hazards associated with improper splinting. Option C is incorrect as it focuses on only one hazard and does not account for the others.

Correct Answer: B

Rationale: Celiac disease, also known as celiac sprue, is a malabsorption disorder affecting the small intestine due to a problem with ingesting gluten, a protein found in wheat, rye, oats, and barley. Therefore, oats or barley cereal would present a problem for a client with Celiac Disease as they contain gluten. Fresh vegetables, butter, coffee, and tea, on the other hand, do not contain gluten and should not pose any issues for individuals with this disorder. Therefore, the correct answer is oats or barley cereal. Choices A, C, and D are not problematic for clients with Celiac Disease as they are gluten-free.
