ATI Pharmacology Exam Practice Questions
Question 1 of 5
Which drug type is often used as a first-line treatment for depression due to its side effect profile?
Correct Answer: D
Rationale: SSRIs (e.g., fluoxetine) are first-line for depression-fewer side effects (e.g., no TCA sedation), per guidelines-versus MAOIs (diet risks), beta-blockers (HTN), or TCAs (anticholinergic). SSRIs' safety drives use.
Question 2 of 5
Drugs can cause adverse events in a patient. Bone marrow toxicity is one of the most frequent types of drug-induced toxicity. The most serious form of bone marrow toxicity is:
Correct Answer: A
Rationale: Aplastic anemia is the most severe form of bone marrow toxicity, characterized by pancytopenia and bone marrow failure. It can be life-threatening and requires immediate intervention. Thrombocytosis, leukocytosis, and granulocytosis are not typically associated with drug-induced bone marrow toxicity.
Question 3 of 5
When educating a patient about Regular Insulin, you should include which instruction:
Correct Answer: D
Rationale: When educating a patient about Regular Insulin, you should include the instruction to inject the insulin subcutaneously. Regular insulin is a short-acting insulin that should be injected into the subcutaneous tissue rather than intramuscularly or intravenously. Subcutaneous injection ensures proper absorption and effectiveness of the insulin. It is important to educate the patient on the correct injection technique and site rotation to optimize insulin absorption and minimize the risk of lipodystrophy.
Question 4 of 5
Which drug type is often used as a first-line treatment for depression due to its side effect profile?
Correct Answer: D
Rationale: SSRIs (e.g., fluoxetine) are first-line for depression-fewer side effects (e.g., no TCA sedation), per guidelines-versus MAOIs (diet risks), beta-blockers (HTN), or TCAs (anticholinergic). SSRIs' safety drives use.
Question 5 of 5
Phenobarbital (luminal) is given to a client for a short treatment of anxiety. Which of the following results would indicate a therapeutic serum range of the medication?
Correct Answer: A
Rationale: The therapeutic serum range for phenobarbital (luminal) in the treatment of anxiety is typically 5-10 mcg/ml. This range is considered effective in managing anxiety symptoms while minimizing the risk of side effects associated with higher levels of the medication. Lower serum levels may be ineffective in treating anxiety, while higher levels increase the risk of adverse effects. Therefore, maintaining the serum concentration within the range of 5-10 mcg/ml is optimal for therapeutic benefits with minimal risks.
