1. What does continuous bubbling in the water seal chamber of a chest tube indicate?

• A. An air leak
• B. A blocked chest tube
• C. Normal chest tube function
• D. Continuous drainage from the chest tube

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak in the system. This occurs when air is entering the system through a leak, preventing the lung from fully re-expanding. Choice B, a blocked chest tube, is incorrect as a blocked tube would result in a lack of drainage rather than continuous bubbling. Choice C, normal chest tube function, is incorrect as continuous bubbling signifies an issue. Choice D, continuous drainage from the chest tube, is incorrect as bubbling in the water seal chamber specifically indicates an air leak, not just the presence of drainage.

2. What ECG changes are expected in hypokalemia?

• A. Flattened T waves on ECG
• B. Prominent U waves on ECG
• C. Widened QRS complexes on ECG
• D. ST elevation on ECG

Correct answer: A

Rationale: In hypokalemia, flattened T waves are a common ECG finding due to the decreased extracellular potassium affecting repolarization. Prominent U waves are typically seen in hypokalemia as well, but flattened T waves are the more specific and early ECG change. Widened QRS complexes are associated with hyperkalemia, not hypokalemia. ST elevation is often seen in conditions like myocardial infarction, pericarditis, or early repolarization syndrome, not specifically in hypokalemia.

3. What should be included in teaching for a patient with pre-dialysis end-stage kidney disease?

• A. Limit phosphorus intake to 700 mg/day
• B. Increase protein intake to 1g/kg/day
• C. Increase sodium intake
• D. Limit sodium to 1,500 mg/day

Correct answer: A

Rationale: The correct answer is to limit phosphorus intake to 700 mg/day for a patient with pre-dialysis end-stage kidney disease. Excessive phosphorus intake can lead to further complications in kidney disease, such as bone and cardiovascular issues. Choice B is incorrect as increasing protein intake can put additional stress on the kidneys due to the buildup of urea and other waste products. Choice C is incorrect because increasing sodium intake can worsen hypertension and fluid retention, common issues in kidney disease. Choice D is incorrect as limiting sodium intake is generally recommended in kidney disease to manage blood pressure and fluid balance.

4. What is the priority intervention for a patient with unstable angina?

• A. Administer nitroglycerin
• B. Establish IV access
• C. Auscultate heart sounds
• D. Administer aspirin

Correct answer: A

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient with unstable angina as it helps dilate blood vessels, improve blood flow to the heart, relieve chest pain, and prevent further cardiac damage. Establishing IV access (choice B) may be important but is not the priority over administering nitroglycerin in this scenario. Auscultating heart sounds (choice C) and administering aspirin (choice D) are also important aspects of managing unstable angina, but they are not the immediate priority intervention when a patient is experiencing chest pain.

5. What are the signs of compartment syndrome?

• A. Unrelieved pain, pallor, pulselessness
• B. Muscle weakness, hyporeflexia
• C. Pins-and-needles sensation, swelling
• D. Severe swelling and tightness in the affected extremity

Correct answer: A

Rationale: The correct signs of compartment syndrome include unrelieved pain, pallor, and pulselessness due to increased pressure within a muscle compartment. Choice B, muscle weakness, and hyporeflexia are not typical signs of compartment syndrome. Choice C, pins-and-needles sensation and swelling, are not specific signs of compartment syndrome. Choice D, severe swelling and tightness in the affected extremity, could be seen in compartment syndrome but are not the primary signs.
