Answer to Question 1

B
This patient's INR is only minimally prolonged, so no dose reduction is required. The NP should recheck the INR periodically. If the INR becomes more prolonged, lowering the dose of warfarin is recommended. If the INR approaches 5, omitting a dose and resuming at a lower dose is recommended. Vitamin K is used for an INR of 9 or greater.

Answer to Question 2

B
Doxazosin is a nonspecific B-blocker, which also lowers blood pressure and should be considered to treat BPH in patients who also have hypertension. Tadalafil is used to treat erectile dysfunction. Tamsulosin is a specific -blocker and is first-line treatment for patients with BPH who do not have hypertension. Finasteride is a 5B-reductase inhibitor, which is not a first-line medication.

These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
