ATI Pharmacology Made Easy 4.0 The Hematologic System Questions
Question 1 of 5
Basic component of a blood clot
Correct Answer: A
Rationale: Platelets are the basic component of a blood clot. When there is an injury to a blood vessel, platelets are activated and aggregate at the site to form a plug, which is the first step in the clotting process. Platelets release chemicals that further promote clot formation, eventually leading to the formation of a stable blood clot. While fibrin, thrombin, thromboxane, and ADP are also involved in the clotting process, platelets play a central role in the initial formation of a blood clot.
Question 2 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 3 of 5
The home care nurse is caring for a patient newly prescribed a nonselective beta-blocking agent. What would the nurse include in the teaching plan related to this drug? (Select all that apply.)
Correct Answer: A
Rationale: Patients should be taught to change position slowly, avoid driving or operating hazardous machinery, and to pace activities as a result of potential dizziness from orthostatic hypotension in order to avoid injury. Patients should take medicine with meals when possible. Drug is more likely to decrease libido than increase it. Activity levels should be paced and care should be taken not to overdo. The nurse should provide comprehensive patient education to ensure safe and effective use of the medication.
Question 4 of 5
The nurse is monitoring a patient taking furosemide for heart failure. Which electrolyte imbalance must the nurse be alert for?
Correct Answer: C
Rationale: Furosemide, a loop diuretic, promotes the excretion of potassium, sodium, and water. Hypokalemia (low potassium) is a common side effect and can lead to muscle weakness, arrhythmias, and other complications. Hyperkalemia (A) is unlikely with furosemide. Hypernatremia (B) and hyponatremia (D) are less common but should still be monitored.
Question 5 of 5
A client taking probenecid is complaining of gout pain. Which of the following medication should the nurse expect to be administered?
Correct Answer: A
Rationale: Acetaminophen is often used to manage pain in patients with gout, as it does not interfere with uric acid levels. Aspirin is contraindicated because it can reduce the effectiveness of probenecid. Orphenadrine and tizanidine are muscle relaxants and are not indicated for gout pain. Acetaminophen is a safe and effective option for pain relief in this context.
