Free AGACNP Exam Questions That Helps Candidates Pass

Current guidelines recommend mammography every two years for women aged 50-74 years. For women with a family history of breast cancer, more frequent screening or the use of breast MRI may be considered, but for the general population, biennial mammography is the standard. Clinical breast examinations are no longer recommended as a primary screening tool.

Potassium levels must be closely monitored in patients receiving digoxin because hypokalemia increases the risk of digoxin toxicity. Elevated digoxin levels in the presence of low potassium can cause arrhythmias, which can be life-threatening. Monitoring magnesium, calcium, and sodium are also important, but potassium is the most critical for digoxin therapy.

The patient's history of smoking, hemoptysis, weight loss, and persistent cough raises concern for lung cancer. Smoking is the primary risk factor for lung cancer, and these symptoms are characteristic of advanced disease. Tuberculosis could also cause a persistent cough and weight loss, but hemoptysis and the patient’s risk factors point more toward lung cancer. Pneumonia and chronic bronchitis typically present with different clinical features.

The patient’s difficulty swallowing solid foods and history of GERD are most consistent with esophageal stricture, a narrowing of the esophagus often caused by long-term acid reflux. This can lead to dysphagia, especially for solids. Achalasia also causes dysphagia, but it typically affects both solids and liquids and presents with more severe symptoms over time. Esophageal cancer could be considered in patients with risk factors like smoking or alcohol use, but the clinical presentation is more typical of a benign stricture.

In patients with CKD, especially those receiving diuretics for heart failure, monitoring for hypotension is critical. Diuretics can cause volume depletion, leading to hypotension and worsening kidney function. Hyperkalemia, hyperglycemia, and ensuring adequate fluid intake are also important, but hypotension is the most immediate concern when administering diuretics.
