Answer to Question 1

D
Feedback:
The choice of antibiotics in a clinical situation is determined by assessing which drug will affect the causative organism and lead to the fewest adverse effects. Selective toxicity is the ability of the drug to kill foreign cells without causing harm to the human body cells. How the antibiotic works to kill bacteria varies by drug type and may reduce the ability to reproduce, damage the cell wall, or interfere with a biochemical reaction, but this is a description of how the antibiotic works and does not describe selective toxicity

Answer to Question 2

C
Feedback:
Many of the herbal remedies are known to alter blood coagulation and should be avoided when taking anticoagulants. Patients taking these drugs should be cautioned to avoid angelica, cat's claw, chamomile, chondroitin, feverfew, garlic, Ginkgo, goldenseal, grape seed extract, green leaf tea, horse chestnut seed, psyllium, and turmeric. If a patient who is taking an anticoagulant presents with increased bleeding and no other interaction or cause is found, question the patient about the possibility of use of herbal therapies. St. John's wort, tarragon, and saw palmetto are not implicated as having an interaction with anticoagulants.
