While caring for a patient scheduled for knee replacement surgery, the nurse provides cefazolin(antibiotic) as ordered 30 minutes preoperatively. Which statement indicates that teaching has been effective?
"This medication will replace vitamins and minerals that may be lost due to bleeding during surgery."
"This is a palliative medication to help ease the pain from surgery."
"This medication will help the surgeon identify areas of bone destruction due to arthritis."
"This antibiotic is given as a prophylactic to help reduce the risk of infection after surgery."
The Correct Answer is D
A. "This medication will replace vitamins and minerals that may be lost due to bleeding during surgery." Cefazolin is an antibiotic, not a replacement for vitamins and minerals. This statement is incorrect.
B. "This is a palliative medication to help ease the pain from surgery."Cefazolin is not a palliative medication; it is an antibiotic used to prevent infection, not to relieve pain.
C. "This medication will help the surgeon identify areas of bone destruction due to arthritis." Cefazolin does not aid in the identification of bone destruction. It is an antibiotic, not a diagnostic tool.
D. "This antibiotic is given as a prophylactic to help reduce the risk of infection after surgery."
This statement is correct. Cefazolin is given prophylactically to reduce the risk of postoperative infection.

Correct Answer is ["A","B","E"]
Explanation
A. Molecular weight: Drugs with lower molecular weight tend to have higher bioavailability because they can more easily pass through biological membranes.
B. Fat or liquid solubility: Drugs that are fat-soluble can cross cell membranes more easily, affecting their bioavailability. Water-soluble drugs may require transport mechanisms, which can limit absorption.
C. Depth of breathing: The depth of breathing primarily affects the absorption of inhaled drugs, not the general bioavailability of orally or intravenously administered medications.
D. Development of a fever: While fever can affect drug metabolism, it doesn’t directly influence the bioavailability of a drug.
E. Presence of food: Food in the stomach can either enhance or inhibit drug absorption, depending on the drug’s characteristics. This directly impacts bioavailability.
Correct Answer is B
Explanation
A. Endangering the elderly: Teratogenicity does not refer to endangering the elderly. It is related to effects on the fetus.
B. Causing birth defects in the unborn fetus: Teratogenic substances are those that can cause birth defects when a pregnant woman is exposed to them.
C. Cancer-causing: Substances that cause cancer are called carcinogens, not teratogens.
D. Endangering the health of the mother: While some teratogens can also affect the mother, the term specifically refers to causing birth defects in the fetus.
