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
The following drugs are most commonly associated with ototoxicity:
Correct Answer: B
Rationale: Gentamicin is highly associated with ototoxicity, especially in patients with preexisting renal impairment or prolonged use.
Question 3 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 4 of 5
A patient is taking levofloxacin. What does the nurse know to be true regarding this drug?
Correct Answer: D
Rationale: Levofloxacin is a fluoroquinolone antibiotic available in both oral and intravenous forms. It is not classified as an aminoglycoside. A well-documented adverse effect of fluoroquinolones is tendon rupture, particularly in older adults and those on corticosteroid therapy. Hypertension is not a common side effect of levofloxacin. Patients should be advised to report any tendon pain or swelling immediately.
Question 5 of 5
What is Heparin's antidote?
Correct Answer: A
Rationale: Protamine sulfate is the antidote for Heparin. Heparin is an anticoagulant medication that works by inhibiting clotting factors in the blood. In cases of Heparin overdose or when a patient needs to quickly reverse the effects of Heparin, Protamine sulfate is administered as an antidote. Protamine sulfate works by binding to Heparin and neutralizing its anticoagulant effects, thus helping to restore normal clotting function. It is important to use Protamine sulfate cautiously as it can cause severe reactions in some individuals, especially those with allergies to fish, as Protamine is derived from fish sperm.
