Question 1 of 5
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.)
Correct Answer: A
Rationale: The correct answer is A: 2 tablets.
To achieve a total dose of 500 mg, the nurse needs to administer 2 tablets of 250 mg each (250 mg x 2 = 500 mg). This ensures the patient receives the prescribed dose accurately.
Choices B to G are incorrect as they do not align with the required dosage calculation.
Question 2 of 5
Which life stage pertains to a 40-year-old patient?
Correct Answer: C
Rationale: The correct answer is C: Adult. At 40 years old, individuals are typically considered to be in the middle adulthood stage, which falls within the broader category of adulthood. This life stage is characterized by increased responsibilities, career development, and family commitments.
Choices A, B, and D are incorrect because they refer to stages typically associated with individuals who are older than 40. Aged and elderly usually refer to individuals who are advanced in age, while "older adult" is a term commonly used for individuals around 65 years and above.
Therefore, C is the best choice as it accurately reflects the life stage of a 40-year-old individual.
Question 3 of 5
Which effect of protein binding on drugs in the bloodstream is accurate?
Correct Answer: D
Rationale: The correct answer is D: Accumulation of the drug. Protein binding can decrease the amount of free drug available for distribution and metabolism, leading to increased drug levels in the bloodstream. This can result in drug accumulation and potential toxicity.
Choice A is incorrect because protein binding typically does not inactivate drugs.
Choice B is incorrect as protein binding does not directly increase the risk of allergic reactions.
Choice C is incorrect as protein binding does not cause precipitation of idiosyncratic reactions.
Question 4 of 5
Which phenomenon occurs in the body as a person ages?
Correct Answer: D
Rationale: The correct answer is D. Lean body mass decreases as a person ages due to factors like decreased physical activity and hormonal changes. This leads to a decline in muscle mass and bone density.
Choice A is incorrect as protein needs actually increase with age to support muscle maintenance.
Choice B is incorrect as total fat content tends to increase with age.
Choice C is incorrect as total body water typically decreases as aging progresses.
Question 5 of 5
Which symptom is the most common with a hypersensitivity reaction to a medication?
Correct Answer: A
Rationale: The correct answer is A: Urticaria. This is the most common symptom in a hypersensitivity reaction to medication due to the release of histamine, causing skin rash and itching. Vomiting (
B) and wheezing (
C) can occur but are less common. Anaphylaxis (
D) is a severe, life-threatening reaction that can include urticaria but is not the most common symptom.
