Free AGACNP Exam Questions That Helps Candidates Pass

The patient’s history of smoking, along with symptoms of a persistent cough, chest pain, and hemoptysis, combined with a mass in the right upper lung field, is highly suggestive of lung cancer. Smoking is the primary risk factor for lung cancer, and these symptoms are classic for the disease. Tuberculosis could also present with a cough and hemoptysis, but it would typically have other systemic symptoms like night sweats. Pneumonia and pulmonary embolism present differently and do not typically cause a mass on X-ray.

The nurse practitioner must respect the patient’s autonomy, which includes the right to refuse the release of their medical records. Even if the family requests the records, the patient’s written consent is required to release them unless there is a court order. Patient confidentiality and autonomy take precedence.

ST-segment elevation in leads II, III, and aVF is indicative of an inferior myocardial infarction (MI). The most appropriate next step is to administer aspirin and clopidogrel to prevent further platelet aggregation, followed by preparation for reperfusion therapy (either thrombolysis or percutaneous coronary intervention). A chest X-ray is not indicated initially, and CABG is typically performed later if necessary.

The symptoms of sudden-onset chest pain radiating to the back, dizziness, and extremely elevated blood pressure are highly suggestive of aortic dissection. Aortic dissection occurs when there is a tear in the inner layer of the aorta, and blood flows between the layers, causing severe chest pain and systemic symptoms. Acute myocardial infarction, pulmonary embolism, and hypertensive crisis could present with chest pain, but the characteristic pain radiation and elevated blood pressure make aortic dissection the most likely diagnosis.

Metformin is contraindicated in patients with impaired kidney function due to the risk of lactic acidosis, a rare but potentially fatal complication. It should be avoided in patients with a creatinine clearance of less than 30 mL/min. Hyperkalemia, hypoglycemia, and hepatotoxicity are not common side effects of metformin, but lactic acidosis is a critical concern, especially in patients with CKD.
