1. What should the nurse do when continuous bubbling is seen 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
D. Continue monitoring the chest tube

Correct answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the nurse should tighten the connections of the chest tube system. This action can often resolve an air leak causing the continuous bubbling. Clamping the chest tube or replacing it would not address the underlying issue of an air leak and may lead to complications. Continuing to monitor the chest tube without taking corrective action may result in the deterioration of the patient's condition.

2. What adverse effect might occur in a patient receiving radiation after a mastectomy?

A. Seizures
B. JVD and fatigue
C. SOB and JVD
D. S3 heart sound

Correct answer: D

Rationale: The correct adverse effect that might occur in a patient receiving radiation after a mastectomy is the development of an S3 heart sound. This can result from decreased pumping ability following mastectomy and radiation treatment. Choice A, seizures, is incorrect as seizures are not a common adverse effect of radiation after a mastectomy. Choice B, JVD and fatigue, is incorrect as while fatigue can be a common side effect, JVD (Jugular Venous Distention) is not typically associated with radiation after a mastectomy. Choice C, SOB (Shortness of Breath) and JVD, is incorrect as while shortness of breath can occur, JVD is not a typical adverse effect of radiation post-mastectomy.

3. What are the expected findings in a patient with hypokalemia?

A. Cardiac dysrhythmias
B. Seizures and confusion
C. Bradycardia
D. Muscle weakness

Correct answer: A

Rationale: The correct answer is A: Cardiac dysrhythmias. Hypokalemia is commonly associated with cardiac dysrhythmias due to the role potassium plays in maintaining proper electrical conduction in the heart. Choices B, C, and D are incorrect. While hypokalemia can lead to muscle weakness, the most critical and life-threatening manifestation is cardiac dysrhythmias. Seizures and confusion are more commonly associated with other electrolyte imbalances, such as hyponatremia. Bradycardia is not a typical finding in hypokalemia, as it tends to cause tachycardia or other arrhythmias.

4. What is a characteristic sign of hypokalemia on an ECG?

A. Flattened T waves
B. ST elevation
C. Prominent U waves
D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are a characteristic sign of hypokalemia on an ECG. When potassium levels are low, it can lead to changes in the ECG, such as T wave flattening. This alteration is important to recognize as it indicates potential electrolyte imbalances. ST elevation (Choice B) is not typically associated with hypokalemia but can be seen in conditions like myocardial infarction. Prominent U waves (Choice C) are associated with hypokalemia, but flattened T waves are more specific. Widened QRS complex (Choice D) is not a typical ECG finding in hypokalemia but can be seen in conditions like hyperkalemia.

5. What should a healthcare provider monitor for in a patient with HIV and a CD4 T-cell count below 180 cells/mm3?

A. Monitor for signs of infection
B. Monitor for anemia
C. Monitor for dehydration
D. Monitor for bleeding

Correct answer: A

Rationale: A CD4 T-cell count below 180 cells/mm3 indicates severe immunocompromise in a patient with HIV. Monitoring for signs of infection is crucial because the patient is at high risk of developing opportunistic infections. Anemia (choice B), dehydration (choice C), and bleeding (choice D) are not directly associated with a low CD4 T-cell count in patients with HIV.
