1. What is the priority lab value to monitor in a patient with HIV?
- A. CD4 T-cell count 180 cells/mm3
- B. White blood cell count 4,500/mm3
- C. Potassium levels 3.5-5.0 mEq/L
- D. Hemoglobin levels below 12g/dL
Correct answer: A
Rationale: The correct answer is A: CD4 T-cell count 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV to assess the status of their immune system. A CD4 count of 180 cells/mm3 indicates severe immunocompromise and a high risk of opportunistic infections. This value is used to guide treatment decisions and assess the need for prophylaxis against specific infections. Choices B, C, and D are incorrect because monitoring white blood cell count, potassium levels, and hemoglobin levels, although important in HIV patients, are not as crucial as monitoring the CD4 T-cell count for assessing immune function and disease progression.
2. What are the expected signs of compartment syndrome?
- A. Unrelieved pain, pallor, and pulselessness
- B. Fever, swelling, and redness
- C. Muscle cramps and weakness
- D. Redness and itching
Correct answer: A
Rationale: The correct answer is A: Unrelieved pain, pallor, and pulselessness. Compartment syndrome is characterized by increased pressure within a muscle compartment, leading to inadequate blood supply. This results in severe pain that is unrelieved by rest or medication, pallor due to compromised blood flow, and pulselessness as a late sign of severe ischemia. Choices B, C, and D are incorrect. Fever, swelling, and redness are not typical signs of compartment syndrome. Muscle cramps and weakness may occur due to other conditions, but they are not primary indicators of compartment syndrome. Redness and itching are also not commonly associated with compartment syndrome.
3. What is the priority intervention when continuous bubbling is observed in the water seal chamber of a chest tube?
- A. Check for an air leak
- B. Continue monitoring as it is not normal
- C. Replace the chest tube system
- D. Tighten the tube connections
Correct answer: A
Rationale: The correct answer is to 'Check for an air leak.' Continuous bubbling in the water seal chamber of a chest tube indicates an air leak, which can compromise the effectiveness of the chest tube in re-expanding the lung. Checking for an air leak is crucial to prevent respiratory complications. Choice B is incorrect because continuous bubbling is not normal and requires immediate intervention to address the air leak. Choice C is incorrect as replacing the entire chest tube system is not the initial priority when an air leak is suspected. Choice D is incorrect because tightening tube connections may not address the underlying issue of an air leak and should not be the initial action taken in this situation.
4. What intervention is needed when continuous bubbling is observed in the chest tube water seal chamber?
- A. Tighten the connections of the chest tube system
- B. Clamp the chest tube
- C. Replace the chest tube system
- D. Continue monitoring the chest tube
Correct answer: A
Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the correct intervention is to tighten the connections of the chest tube system. This can help resolve an air leak that is causing the continuous bubbling. Clamping the chest tube or replacing the entire chest tube system are not appropriate interventions in this scenario. Clamping the tube can lead to a dangerous buildup of pressure, while replacing the chest tube system may not be necessary if the issue can be resolved by simply tightening the connections. Continuing to monitor the chest tube without taking corrective action may lead to complications associated with the air leak.
5. What does continuous bubbling in the water seal chamber of a chest tube indicate?
- A. An air leak
- B. A blockage in the chest tube
- C. Normal chest tube function
- D. Malfunction in the drainage system
Correct answer: A
Rationale: Continuous bubbling in the water seal chamber indicates an air leak in the chest tube system. This bubbling occurs when air is escaping through the tube and entering the water seal chamber. Choice B, a blockage in the chest tube, is incorrect as continuous bubbling does not suggest a blockage. Choice C, normal chest tube function, is incorrect because continuous bubbling is not an expected finding in a properly functioning chest tube. Choice D, a malfunction in the drainage system, is incorrect as continuous bubbling specifically points towards an air leak, not a general malfunction.
