Question 1 of 4
Which of the following antiparkinsonian drugs may cause vasospasm?
Correct Answer: B
Rationale: Bromocriptine, a dopamine D2 agonist used in Parkinson's, has ergot alkaloid properties, which can cause vasospasm by stimulating vascular smooth muscle receptors, occasionally leading to Raynaud's-like symptoms or digital ischemia. Amantadine, an NMDA antagonist, enhances dopamine release but lacks vasoconstrictive effects. Carbidopa inhibits dopa decarboxylase, aiding levodopa delivery without vascular impact. Entacapone, a COMT inhibitor, extends levodopa's duration but doesn't affect vessels. Ropinirole, a non-ergot agonist, avoids vasospasm. Bromocriptine's ergot-derived vasoconstriction, though rare, distinguishes it among antiparkinsonian drugs, requiring caution in patients with vascular risks.
Question 2 of 4
The nurse is managing the care of a group of patients with schizophrenia. The patients are receiving conventional antipsychotic medications. When assessing for anticholinergic side effects, which would the nurse immediately report to the physician?
Correct Answer: D
Rationale: Conventional antipsychotics (e.g., haloperidol) cause anticholinergic effects like urinary retention , a potential emergency risking bladder damage, requiring immediate reporting. Dystonia is extrapyramidal, not anticholinergic. Headache and hypertension aren't typical anticholinergic signs. D prioritizes urgent intervention, making it the correct choice.
Question 3 of 4
A client with type 2 diabetes is prescribed insulin glargine (Lantus). Which statement by the client indicates a need for further teaching?
Correct Answer: B
Rationale: Insulin glargine, a long-acting basal insulin, provides steady glucose control without a peak. Mixing it with regular insulin is incorrect'glargine's pH precipitates if combined, altering its action, indicating a teaching need. Same-time injection ensures consistency. Overnight control and no peak align with its 24-hour, flat profile. The misconception about mixing risks erratic glucose levels, critical in type 2 diabetes where stability is key. Further teaching must clarify glargine's unique formulation, preventing administration errors that could lead to hypo- or hyperglycemia, making B the statement requiring correction.
