What are the key differences between viral and bacterial infections?
- A. Viral infections typically last longer than bacterial infections.
- B. Bacterial infections typically cause high fever.
- C. Both bacterial and viral infections cause rashes.
- D. Viral infections cause sudden onset of symptoms.
Correct Answer: A
Rationale: The correct answer is A. Viral infections typically last longer than bacterial infections. This is because viral infections often require the body's immune system to fight off the virus, leading to a longer duration of illness. Bacterial infections, on the other hand, often cause a rapid onset of symptoms due to the toxins produced by bacteria. Choice B is incorrect because not all bacterial infections cause high fever. Choice C is incorrect because rashes can be caused by both bacterial and viral infections, but not always. Choice D is incorrect because while some viral infections may cause a sudden onset of symptoms, it is not a key distinguishing factor between viral and bacterial infections.

What is the proper technique for measuring blood pressure manually?
- A. Use a stethoscope to listen for the Korotkoff sounds
- B. Ensure the patient is seated with the arm supported
- C. Use a manual sphygmomanometer
- D. Deflate the cuff slowly while listening to the heartbeat
Correct Answer: A
Rationale: The correct technique for measuring blood pressure manually involves using a stethoscope to listen for the Korotkoff sounds. Choice B, ensuring the patient is seated with the arm supported, is important but not the specific technique for measuring blood pressure. Choice C, using a manual sphygmomanometer, is a necessary tool but not the technique itself. Choice D, deflating the cuff slowly while listening to the heartbeat, is not the correct technique as the deflation should be done while listening for the Korotkoff sounds to determine the systolic and diastolic blood pressure readings.
When providing discharge teaching to a client with diabetes, what is the most important instruction?
- A. Check blood sugar levels once daily
- B. Administer insulin as prescribed before meals
- C. Take medication only when feeling unwell
- D. Eat carbohydrate-rich meals to stabilize blood sugar
Correct Answer: B
Rationale: Administering insulin as prescribed before meals is crucial for managing diabetes. This instruction is vital as it helps the client maintain blood sugar levels within the target range. Checking blood sugar levels once daily is important but not as critical as ensuring the timely administration of insulin. Taking medication only when feeling unwell is dangerous as it may lead to uncontrolled blood sugar levels. Eating carbohydrate-rich meals may actually destabilize blood sugar levels rather than stabilizing them, making it an incorrect choice.
How should a healthcare professional manage a patient with congestive heart failure?
- A. Administer diuretics and monitor fluid balance
- B. Provide a high-sodium diet and restrict fluids
- C. Administer oxygen and provide pain relief
- D. Provide bronchodilators and encourage mobility
Correct Answer: A
Rationale: Correct answer: The most appropriate management for a patient with congestive heart failure is to administer diuretics to help remove excess fluid and monitor fluid balance. Diuretics help reduce the workload on the heart and alleviate symptoms of fluid overload. Choice B is incorrect because patients with congestive heart failure are usually advised to limit sodium intake and carefully monitor fluid intake. Choice C is incorrect because although oxygen therapy may be necessary in certain cases, it is not the primary management for congestive heart failure. Pain relief is not a primary intervention for this condition. Choice D is incorrect because bronchodilators are not the first-line treatment for congestive heart failure. Encouraging mobility is important, but administering diuretics and monitoring fluid balance take precedence in managing this condition.
A client is learning to use a cane. What instruction is essential for this client?
- A. Advance the cane and the weaker leg at the same time
- B. Maintain two points of support on the ground at all times
- C. Use the cane on the weaker side for better support
- D. Advance the cane 30 to 45 cm with each step
Correct Answer: B
Rationale: The correct instruction for a client learning to use a cane is to maintain two points of support on the ground at all times. This ensures better stability and reduces the risk of falls. Choice A is incorrect because advancing the cane and the weaker leg simultaneously may lead to imbalance. Choice C is incorrect because the cane should be used on the stronger side to provide support. Choice D is incorrect because there is no specific measurement for advancing the cane with each step, and the focus should be on maintaining stability.
A nurse is contributing to the plan of care for a client who has a chest tube connected to a closed drainage system. Which of the following interventions should the nurse include?
- A. Clamp the chest tube
- B. Maintain the drainage below the level of the chest
- C. Elevate the chest tube above chest level
- D. Avoid frequent dressing changes
Correct Answer: B
Rationale: The correct intervention for a client with a chest tube connected to a closed drainage system is to maintain the drainage below the level of the chest. This position allows proper drainage of fluids and helps prevent complications such as backflow of blood or fluids into the chest cavity. Clamping the chest tube (Choice A) is incorrect as it can lead to a tension pneumothorax. Elevating the chest tube above chest level (Choice C) is also incorrect because it can impede proper drainage. Avoiding frequent dressing changes (Choice D) is important to prevent introducing infection, but it is not directly related to the position of the drainage system.
