ATI Pharmacology Assessment 2 Questions
Question 1 of 5
A 48-year-old man presents to the emergency department in the morning with urticaria and difficulty breathing following a bee sting received while gardening. He is treated, recovers, and is sent home. Later that evening, his symptoms return and he is treated again in the emergency department. He denies having been stung again. What should have been given to this patient to avoid his return to the emergency department?
Correct Answer: D
Rationale: Recurrent allergic symptoms post-bee sting suggest ongoing inflammation. Prednisolone , a corticosteroid, reduces late-phase reactions. Diphenhydramine and Loratadine treat acute symptoms. Epinephrine is for anaphylaxis but short-acting. Prednisolone prevents biphasic reactions, avoiding his return.
Question 2 of 5
Which of the following combinations of antiparkinsonian drugs is appropriate treatment plan?
Correct Answer: B
Rationale: Levodopa, the cornerstone of Parkinson's treatment, converts to dopamine in the brain. Carbidopa inhibits peripheral dopa decarboxylase, increasing levodopa's CNS availability and reducing side effects. Entacapone, a COMT inhibitor, prolongs levodopa's half-life by preventing its peripheral breakdown, enhancing efficacy. This trio targets dopamine synthesis and metabolism synergistically, a standard advanced-stage regimen. Amantadine lacks synergy with carbidopa/entacapone, focusing on NMDA antagonism. Pramipexole (dopamine agonist) with carbidopa/entacapone is less common, as carbidopa pairs with levodopa. Ropinirole and selegiline boost dopamine but miss levodopa's direct effect; entacapone's role weakens without levodopa. The levodopa-carbidopa-entacapone combination optimizes dopamine delivery, making it a clinically proven and appropriate plan.
Question 3 of 5
The nurse has completed medication education with the patient who is receiving risperidone (Risperdal). The nurse evaluates that the education has been effective when the patient makes which statement?
Correct Answer: B
Rationale: Risperidone, an atypical antipsychotic, can cause agranulocytosis, a rare but life-threatening drop in white blood cells, necessitating regular blood monitoring . This statement reflects understanding of a critical safety measure, indicating effective education. Nightmares aren't a primary concern with risperidone. Weight loss contrasts with its common side effect of weight gain, making it less relevant. Metallic taste isn't associated with this drug. The nurse evaluates learning based on recognition of monitoring for severe adverse effects like agranulocytosis, ensuring patient safety, making choice B the best indicator of comprehension.
Question 4 of 5
The patient with schizophrenia is sitting quietly in a chair. The patient does not respond much to what is happening and has a lack of interest in the environment. How does the nurse interpret this assessment?
Correct Answer: D
Rationale: Schizophrenia's negative symptoms include apathy and withdrawal, seen in quietness and disinterest . Depression needs more evidence. Voices suggest positive symptoms, absent here. Positive symptoms add behaviors, not subtract. D aligns with schizophrenia's clinical presentation, making it the correct interpretation.
Question 5 of 5
A client is prescribed prednisone for rheumatoid arthritis. Which side effect should the nurse teach the client to report immediately?
Correct Answer: C
Rationale: Prednisone, a corticosteroid, manages inflammation but risks serious side effects. Blurred vision may signal glaucoma or cataracts, ocular emergencies requiring immediate reporting to prevent vision loss. Increased appetite and weight gain are common, manageable effects of cortisol excess. Mood swings occur due to CNS effects but are less urgent unless severe. Blurred vision stands out as a rare but critical adverse reaction, linked to prednisone's long-term impact on intraocular pressure or lens opacity. Teaching this ensures early detection, aligning with corticosteroid monitoring where eye complications can escalate fast. Appetite, weight, and mood changes, while disruptive, don't match this urgency, making C the priority side effect for the client to report promptly.
