ATI Pharmacology Made Easy 4.0 The Hematologic System Questions
Question 1 of 5
A patient presents fully conscious with acute falciparum malaria following a visit to Nigeria. Which of the following treatments is most appropriate?
Correct Answer: B
Rationale: Acute falciparum malaria from Nigeria, a chloroquine-resistant area, requires effective therapy. Chloroquine is ineffective due to resistance. Proguanil/atovaquone (Malarone) treats uncomplicated falciparum malaria, rapid-acting and well-tolerated, most appropriate here. Primaquine targets liver stages, not acute blood infection. Pyrimethamine and hydroxychloroquine are less effective. Malarone's efficacy ensures rapid parasite clearance, vital in this potentially severe disease.
Question 2 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 3 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 4 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 5 of 5
The patient receives aspirin. The nurse assesses an adverse effect to this drug when the patient makes which response?
Correct Answer: A
Rationale: Aspirin, an NSAID, inhibits platelet aggregation and can cause gastrointestinal bleeding, leading to dark, tarry stools (melena) from upper GI hemorrhage . This adverse effect requires urgent assessment, as it signals potential internal bleeding, a serious complication. Nasal stuffiness isn't linked to aspirin unless related to an allergic reaction (rare). Headaches from lights suggest photophobia, unrelated to aspirin's effects. Frequent urination isn't a typical side effect. The nurse identifies dark stools as a critical sign of aspirin's impact on gastric mucosa and coagulation, necessitating intervention, making choice A the correct adverse effect to assess.
