ATI Pharmacology Made Easy 4.0 The Hematologic System Questions
Question 1 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.
Question 2 of 5
A patient has been taking a beta blocker for 4 weeks as part of his antianginal therapy. He also has type II diabetes and hyperthyroidism. When discussing possible adverse effects, the nurse will include which information?
Correct Answer: A
Rationale: Option E is the correct answer. When a patient with type II diabetes is taking a beta blocker, it's important to monitor blood glucose levels regularly for possible changes in glucose levels. Beta blockers can mask the symptoms of hypoglycemia, such as tremors and rapid heartbeat, which can make it harder for patients to recognize when their blood sugar is too low. On the other hand, beta blockers can also potentially lead to hyperglycemia as they can blunt the body's response to hypoglycemia by inhibiting the release of counter-regulatory hormones like epinephrine. Therefore, monitoring blood glucose levels is crucial in such patients to prevent complications related to blood sugar fluctuations.
Question 3 of 5
The physician has prescribed haloperidol (Haldol) for the patient with schizophrenia. What is the priority patient outcome?
Correct Answer: B
Rationale: Haloperidol treats schizophrenia's positive symptoms, but compliance is the priority outcome, as relapse follows non-adherence. Fluids/fiber manage side effects. Hallucination reduction depends on compliance. Restlessness signals issues, not a goal. B ensures treatment success, making it the priority.
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
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.
