Lung Cancer Case Study
A 60-year-old patient presents for a routine checkup. He is a former cigarette smoker with a 60-pack-year smoking history, but he quit smoking 5 years ago. He denies any chest pain, cough, shortness of breath, or weight loss. Which of the following is the most appropriate screening method for lung cancer in this patient?
A: 3 consecutive sputum samples for cytology B: Chest radiography
• The reason this is the wrong answer is because there is no mortality benefit that is associated with the yearly screening with a chest radiography.
C: Low-dose CT of the chest
• Because of the lack of mortality benefit from chest radiograph a low dose CT is recommended. Studies show that low-dose CT of the chest can identify early asymptomatic lung cancer. The USPSTF …show more content…
Give 3 common reasons for a patient to develop ATN. (3 points)
A: 1. Statin Use 2. Prophylactic Nitrofurantion treatment 3. Myoglobin or other endogenous chemicals
There are a multitude of causes of ATN some of them include hypovolemic states such as hemorrhaging, GI and Renal loss as well as fluid sequestration. Another common cause is from antibiotics such as aminoglycosides. Anywhere between 10-30% of patients on aminoglycosides are likely to experience some form of toxic side effects even when the drug is within therapeutic levels. Another drug that is commonly associated with ATN is Ampotericin B especially when the patient is a male and is taking the maximum dose. http://emedicine.medscape.com/article/238064-overview#a6 Grader Feedback: common reasons
