ATI Capstone Adult Medical Surgical Assessment 2

Correct Answer: A

Rationale: The correct intervention for continuous bubbling in the chest tube water seal chamber is to tighten the connections of the chest tube system. Continuous bubbling indicates an air leak in the system, and tightening the connections can help resolve this issue. Clamping the chest tube (Choice B) is not appropriate and can lead to complications by obstructing the drainage system. Similarly, replacing the entire chest tube system (Choice C) may not be necessary if the issue can be resolved by tightening the connections. Continuing to monitor the chest tube (Choice D) without taking action to address the continuous bubbling may delay necessary interventions to prevent complications.

Correct Answer: A

Rationale: The correct answer is to monitor for hypoglycemia. Insulin administration based on a misread glucose level can lead to hypoglycemia due to the unnecessary lowering of blood sugar levels. Monitoring for hypoglycemia involves assessing the patient's blood glucose levels frequently, observing for signs and symptoms such as shakiness, confusion, sweating, and administering glucose if hypoglycemia occurs. Choice B, monitoring for hyperkalemia, is incorrect as insulin administration typically lowers potassium levels. Choice C, administering glucose IV, is not the immediate action needed as the patient could potentially develop hypoglycemia from the excess insulin. Choice D, documenting the incident, is important but not the immediate priority when dealing with a potential hypoglycemic event.

Correct Answer: A

Rationale: When caring for a patient with an air leak in the chest tube system, the nurse should tighten the connections of the chest tube system. This action can help resolve the air leak by ensuring there are no loose connections or leaks in the system. Continuing to monitor the patient (Choice B) is important, but addressing the air leak is a priority. Replacing the chest tube system (Choice C) may not be necessary if tightening the connections resolves the issue. Clamping the chest tube (Choice D) is not appropriate as it can lead to tension pneumothorax.

Correct Answer: A

Rationale: Flattened T waves are an early indicator of hypokalemia on an ECG. Hypokalemia primarily presents with flattened T waves, not prominent U waves, widened QRS complexes, or tall T waves. Prominent U waves are associated with hypokalemia only in severe cases. Widened QRS complexes are more indicative of hyperkalemia, while tall T waves are seen in hyperkalemia as well.

Correct Answer: A

Rationale: The correct answer is A: CD4 T-cell count below 180 cells/mm3. Monitoring CD4 T-cell count is crucial in patients with HIV as it reflects the status of their immune system. A CD4 count below 200 cells/mm3 is indicative of severe immunocompromise, necessitating close monitoring and potential intervention. Choices B, C, and D are less specific to HIV management and do not directly reflect the immune status in these patients. Hemoglobin levels are more relevant for assessing anemia, serum albumin levels for nutritional status, and white blood cell count for overall immune response, but none are as directly tied to HIV disease progression as the CD4 T-cell count.
