Question 1 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 2 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 3 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 4 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.
Question 5 of 5
Which aspect of pharmacokinetics should the nurse be most concerned with when caring for a patient with abnormal functioning of hepatic enzymes?
Correct Answer: D
Rationale: The correct answer is D: Metabolism. When hepatic enzymes are abnormal, it affects the liver's ability to metabolize drugs. This can lead to drug toxicity or reduced drug effectiveness. The nurse should closely monitor drug dosages and frequency to prevent adverse effects. Absorption (
A) may be affected by liver dysfunction but is less critical than metabolism in this scenario. Distribution (
B) and Excretion (
C) are more related to renal function than hepatic enzymes. The other choices (E, F, G) are not applicable. In summary, impaired hepatic metabolism can significantly alter drug response, making it the primary concern for the nurse.
