ATI Capstone Medical Surgical Assessment 1 Quizlet

Correct Answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the appropriate intervention is to tighten the connections of the chest tube system. This action can help resolve an air leak, which is often the cause of continuous bubbling in the water seal chamber. Clamping the chest tube (choice B) is not recommended as it can lead to a dangerous increase in pressure within the chest. Replacing the chest tube (choice C) is not the initial intervention unless there are other indications to do so. Simply monitoring the chest tube (choice D) without taking corrective action will not address the underlying issue of the air leak causing continuous bubbling.

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.

Correct Answer: A

Rationale: When a patient with a chest tube is found to have an air leak, the priority action for the nurse is to check the tube connections. This step helps identify the source of the air leak, which can be caused by loose or disconnected tube connections. Once the source of the leak is identified and addressed, further interventions may be necessary. Replacing or removing and reinserting the chest tube should not be the initial response unless there are specific indications for these actions. Documenting the incident is important but comes after addressing the immediate concern of the air leak.

Correct Answer: A

Rationale: Administering sublingual nitroglycerin is the priority intervention when a patient presents with chest pain and suspected acute coronary syndrome. Nitroglycerin helps dilate blood vessels, improve blood flow to the heart, and relieve chest pain. It is crucial to address the pain and potential ischemia promptly to prevent further cardiac tissue damage. Getting IV access, auscultating heart sounds, and obtaining cardiac enzymes are important assessments and interventions, but administering nitroglycerin takes precedence in managing acute coronary syndrome.

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.
