A nurse is preparing to administer amoxicillin 500 mg PO. Available is amoxicillin 250 mg tablets.
How many tablets should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Full Explanation
The correct answer is 2 tablets. Step 1 is to divide the prescribed dose by the available dose. So, 500 mg ÷ 250 mg = 2. Rationale: The nurse needs to administer the amount of medication that will equal the prescribed dose. Since each tablet contains 250 mg of amoxicillin, two tablets will provide the 500 mg dose.
So, the correct answer is 2 tablets.

Which life stage pertains to a 40-year-old patient?.
A. Aged.
The term “Aged” generally refers to individuals who are in the late stages of life, often those over 652. This does not apply to a 40-year-old patient.
B. Elderly.
“Elderly” is a term often used to refer to individuals who are 65 years of age or older. A 40-year-old patient does not fall into this category.
C. Adult.
A 40-year-old patient is considered an “Adult”. According to Erikson’s stages of development, the stage of “generativity vs. stagnation” begins at age 40 and lasts until age 653.
D. Older adult.
“Older adult” typically refers to individuals who are in their late 60s and beyond. This does not apply to a 40-year-old patient.

Which effect of protein binding on drugs in the bloodstream is accurate?.
A. Inactivation of the drug.
Protein binding does not inactivate the drug. Instead, it can affect the drug’s distribution and bioavailability.
B. Increased risk of allergic reaction.
Protein binding does not directly increase the risk of an allergic reaction. Allergic reactions are typically immune responses to a drug, not a result of protein binding.
C. Precipitation of an idiosyncratic reaction.
An idiosyncratic reaction is an unusual or unexpected reaction to a drug, which is not related to protein binding.
D. Accumulation of the drug.
Protein binding can lead to the accumulation of the drug. Drugs often cannot cross membranes mainly due to the high molecular mass of the drug-protein complex, resulting in the accumulation of the active compounds.

Which phenomenon occurs in the body as a person ages?.
A. Protein needs post-acute accentuate.
Protein needs do not necessarily accentuate with age. In fact, they may decrease due to reduced physical activity and metabolic rate.
B. Total fat content decreases.
Total fat content does not decrease with age. It’s common for fat distribution to change and increase in certain areas.
C. Total body water increases.
Total body water does not increase with age. It usually decreases due to the loss of muscle mass and increase in fat content.
D. Lean body mass decreases.
Lean body mass decreases as a person ages. This is a common phenomenon due to changes in cells and tissues.
