ATI Pharmacology Made Easy 4.0 The Hematologic System Questions
Question 1 of 5
The following are side effects of SSRI's EXCEPT:
Correct Answer: B
Rationale: SSRIs (e.g., fluoxetine) can cause rash as a hypersensitivity reaction, true. Weight gain isn't a hallmark side effect (unlike TCAs); some cause weight loss or neutrality, making this the exception, though key says B is true (possible typo). Sexual dysfunction (e.g., delayed ejaculation) is common, true. Anxiety can occur initially, true. GI symptoms like nausea are frequent. Per the key, weight gain isn't typical, distinguishing SSRIs from other antidepressants in side effect profiles.
Question 2 of 5
Pharmacogenetics is a relatively new area within pharmacology. Which statement best describes the potential of this new area?
Correct Answer: A
Rationale: Pharmacogenetics tailors drugs to genetic profiles (e.g., CYP2C19 for clopidogrel), minimizing unpredictable idiosyncratic responses like rashes. Reducing drug numbers or errors isn't genetics-driven. Cost and efficacy improve indirectly. Customization prevents adverse reactions, its core potential.
Question 3 of 5
The patient has bipolar disorder and is in a manic phase. The physician prescribes lithium (Eskalith). The patient's current lithium level is 0.4. What will the nurse expect to assess in this patient?
Correct Answer: B

Question 4 of 5
A 5-year-old boy is brought to his primary care physician by his parents who say that he often has trouble catching his breath when he has been playing hard outside. He is allergic to peanuts. At the moment, he is breathing fine. Which of the following drugs is commonly used to diagnose suspected asthma?
Correct Answer: B
Rationale: Suspected asthma in a child with exertional dyspnea requires diagnostic confirmation. Methacholine , a muscarinic agonist, provokes bronchoconstriction in asthmatics during a challenge test, confirming airway hyperresponsiveness. Albuterol is a bronchodilator for treatment, not diagnosis. Neostigmine , a cholinesterase inhibitor, is unrelated. Nicotine and Pilocarpine (E) are irrelevant. Methacholine's ability to induce reversible bronchospasm, measured by spirometry, distinguishes asthmatics from normals, making it standard for diagnosis when symptoms are intermittent, as here.
Question 5 of 5
A 13-year-old male has begun having spells of wheezing and difficulty breathing while playing outside. He is diagnosed with asthma and given an inhaler to treat acute attacks. His medication is working well, but he would also like something to prevent attacks from happening. Which of the following drugs would be best to add to his regimen?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
