Nursing Elites

1. 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.

2. A nurse is reviewing the medical record of a client who is receiving warfarin for atrial fibrillation. Which of the following findings should the nurse report to the provider?

• A. International normalized ratio (INR) of 2.5
• B. Platelet count of 180,000/mm³
• C. Prothrombin time (PT) of 12 seconds
• D. Partial thromboplastin time (PTT) of 30 seconds

Correct answer: C

Rationale: A prothrombin time (PT) of 12 seconds is below the therapeutic range for warfarin and indicates a need for dosage adjustment. The correct answer is C. A normal International normalized ratio (INR) for a client on warfarin therapy is usually between 2.0 to 3.0; therefore, an INR of 2.5 is within the expected range. A platelet count of 180,000/mm³ is within the normal range (150,000 to 450,000/mm³) and does not require immediate reporting. A partial thromboplastin time (PTT) of 30 seconds is also within the normal range (25-35 seconds) and does not indicate a need for urgent action.

3. A nurse is educating a client on how to use a cane due to left-leg weakness. What should the nurse include in the teaching?

• A. Use the cane on the stronger side
• B. Advance the cane and the weaker leg at the same time
• C. Use the cane on the weaker side
• D. Advance the cane 30 to 45 cm (12-18 in) with each step

Correct answer: A

Rationale: The correct answer is to use the cane on the stronger side. By doing so, the client will have better support and balance. Choice B is incorrect because advancing the cane and the weaker leg at the same time may lead to instability and falls. Choice C is incorrect as using the cane on the weaker side does not provide optimal support. Choice D is incorrect as advancing the cane 30 to 45 cm (12-18 in) with each step is not a standard recommendation for cane use.

4. Which assessment finding is expected with myxedema?

• A. Increased pulse rate
• B. Decreased temperature
• C. Fine tremors
• D. Weight loss

Correct answer: B

Rationale: Myxedema is characterized by a decreased metabolic rate, leading to manifestations such as decreased temperature. Therefore, the correct assessment finding expected with myxedema is a decreased temperature. Choices A, C, and D are incorrect because myxedema typically presents with a decreased pulse rate, not an increased pulse rate, absence of fine tremors (which are more common in hyperthyroidism), and weight gain rather than weight loss.

5. A client is postoperative following hip replacement surgery. Which of the following instructions should the nurse include in preventing dislocation of the prosthesis?

• A. Cross your legs at the knees
• B. Avoid bending your hip more than 90 degrees
• C. Sit with your legs elevated
• D. Avoid placing a pillow under your knees

Correct answer: B

Rationale: To prevent dislocation of the prosthesis after hip replacement surgery, it is essential to avoid bending the hip more than 90 degrees. This precaution helps maintain the stability of the hip joint and reduces the risk of prosthesis dislocation. Crossing legs at the knees (Choice A) can increase pressure on the hip joint, leading to instability. Sitting with legs elevated (Choice C) and avoiding placing a pillow under the knees (Choice D) do not directly address the risk of prosthesis dislocation.
