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."

Answer and Explanation

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 C

Explanation

A. Hemoglobin 12 mg/dL: Hemoglobin levels reflect the oxygen-carrying capacity of the blood and are not directly related to kidney function or medication dosage adjustments. This value is within the normal range and does not suggest a need for medication dosage changes.

B. Glucose 100 mg/dL: Blood glucose levels are not directly related to kidney function and do not indicate the need to adjust medication dosages. This value is within normal limits.

C. Creatinine 8 mg/dL: Creatinine levels are a key indicator of kidney function. A creatinine level of 8 mg/dL is significantly elevated, suggesting severe renal impairment. Medications that are excreted by the kidneys may need to be dosed lower or avoided altogether to prevent toxicity.

D. Potassium 4.0 mEq/L: This is a normal potassium level and does not indicate the need for medication dosage adjustments. While potassium levels are important in kidney disease, this specific value does not suggest a dosage change is necessary.

A. distribution B. absorption. C. metabolism D. Excretion

Correct Answer is D

Explanation

A. Distribution: Distribution refers to the process of a drug moving through the bloodstream to various tissues in the body, not leaving the body.

B. Absorption: Absorption is the process by which a drug enters the bloodstream from the site of administration. It is not related to the drug leaving the body.

C. Metabolism: Metabolism is the process by which the body breaks down a drug, typically in the liver, before it is excreted.

D. Excretion: Excretion is the correct term. It refers to the process by which drugs and their metabolites are eliminated from the body, primarily through the kidneys (urine) or the gastrointestinal tract (feces).
