ATI Capstone Adult Medical Surgical Assessment 2

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 the CD4 T-cell count is crucial in patients with HIV as it indicates the level of immunocompromise. A CD4 T-cell count below 180 cells/mm3 signifies severe immunosuppression and an increased risk of opportunistic infections. Serum albumin levels (choice B) are important for nutritional status assessment but not specific to HIV monitoring. Hemoglobin levels (choice C) are important for assessing anemia but do not directly reflect HIV disease progression. White blood cell count (choice D) is a general marker of inflammation and infection, but monitoring CD4 T-cell count is more specific and crucial in managing HIV.

Correct Answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak. This situation requires immediate attention to prevent complications such as lung collapse. A blocked chest tube would typically result in absent or fluctuating bubbling. Drainage from the site would be observed in the collection chamber, not the water seal chamber. A blood clot in the chest tube would lead to cessation of drainage.

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.

Correct Answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. This medication helps to dilate the blood vessels, reduce the workload on the heart, and improve blood flow to the heart muscle, providing immediate relief for chest pain in acute coronary syndrome. Administering aspirin is also crucial in the early management of acute coronary syndrome to prevent further clot formation. However, in terms of immediate symptom relief, nitroglycerin takes precedence over aspirin. Obtaining IV access is important for administering medications and fluids but is not the priority over providing immediate relief for chest pain. Checking cardiac enzymes is essential for diagnosing acute coronary syndrome but is not the immediate priority when a patient is experiencing chest pain.
