Correct Answer: A

Rationale: The correct answer is A: Immobilize the client. This is crucial to prevent further damage to the spinal cord. Moving a client with a suspected spinal cord injury can worsen the injury and lead to permanent damage. Immobilizing the client helps maintain spinal alignment and reduces the risk of paralysis. Providing pain relief (B) and loosening clothing (D) are important but secondary actions. Applying pressure to the chest (C) is not recommended for a suspected spinal cord injury as it can also exacerbate the injury.

Correct Answer: A

Rationale: The correct answer is A: Administer glucose. When caring for a client with suspected hypoglycemia, the first priority is to raise their blood sugar levels quickly to prevent potential complications such as seizures or loss of consciousness. Administering glucose helps to rapidly increase blood sugar levels and alleviate symptoms. The other choices (B: Administer insulin, C: Place the client in a supine position, D: Administer IV fluids) are incorrect because administering insulin can further lower blood sugar levels, placing the client in a supine position may not address the immediate issue of low blood sugar, and administering IV fluids does not directly address the hypoglycemia.

Correct Answer: C

Rationale: The correct answer is C: Diagnostic hypothesis. Nurses use diagnostic reasoning to formulate diagnostic hypotheses based on patient data and clinical judgment. They analyze symptoms and data to generate potential diagnoses. Choice A, nursing diagnosis, involves identifying patient problems related to nursing care. Choice B, medical diagnosis, is made by physicians to identify diseases or medical conditions. Choice D, diagnostic assessment, refers to the process of collecting and analyzing data to make a diagnosis. Diagnostic hypothesis aligns with the process of diagnostic reasoning in nursing practice.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. This is the priority intervention to address severe shortness of breath, ensuring the client receives adequate oxygenation. Administering oxygen helps improve oxygen saturation levels and supports respiratory function. Encouraging deep breathing (B) may exacerbate the client's distress. Elevating the head of the bed (C) can help improve breathing but does not address the immediate need for oxygen. Administering antibiotics (D) is not indicated for shortness of breath unless there is an underlying infection causing it.

Correct Answer: A

Rationale: The correct answer is A: Administer epinephrine. The priority in a severe allergic reaction is to quickly address the life-threatening symptoms like anaphylaxis. Epinephrine is the first-line treatment as it helps reverse the effects of the allergic reaction by opening airways and increasing blood pressure. Administering antihistamines (choices B and D) can help relieve itching and hives but are not as effective in treating severe symptoms. Monitoring respiratory status (choice C) is important but administering epinephrine takes precedence to stabilize the client's condition.
