Question 1 of 5
A 52-year-old man who works as an air traffic controller has seasonal allergies. Currently, he is very symptomatic but cannot miss work because of staffing issues. Which of the following agents would be best suited for this patient?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Which of the following medications reduces immune system-mediated inflammation via inhibition of pyrimidine synthesis to reduce the number of activated lymphocytes in the CNS?
Correct Answer: C
Rationale: Teriflunomide, used in multiple sclerosis, inhibits dihydroorotate dehydrogenase, blocking pyrimidine synthesis critical for lymphocyte proliferation, reducing CNS inflammation by limiting activated immune cells. Riluzole modulates glutamate for ALS, not immunity. Rotigotine, a dopamine agonist, treats Parkinson's. Dexamethasone, a corticosteroid, suppresses inflammation broadly via glucocorticoid pathways, not pyrimidine-specific mechanisms. Teriflunomide's targeted action on lymphocyte replication distinguishes it in MS, decreasing relapses by curbing immune-mediated damage, a precise fit for this description.
Question 3 of 5
The client is receiving oxytocin (Pitocin) for induction of labor. Which assessment finding will most likely result in the nurse stopping the infusion?
Correct Answer: A
Rationale: Oxytocin induces labor by stimulating uterine contractions, but excessive use can cause hyperstimulation, leading to continuous, sustained contractions . This risks uterine rupture or fetal distress, necessitating immediate cessation of the infusion to protect mother and baby. Transition is a labor stage, not a reason to stop unless complications arise. Strong contractions are expected, and regular contractions every 2-3 minutes are normal for labor induction. The nurse stops the infusion for sustained contractions due to their potential for catastrophic outcomes, making choice A the most likely trigger based on oxytocin's safety profile.
Question 4 of 5
Potential causes for respiratory alkalosis include
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
The nurse administers lorazepam (Ativan) to a client with anxiety. Which statement by the client indicates understanding of the medication?
Correct Answer: B
Rationale: Lorazepam, a benzodiazepine, reduces anxiety via GABA enhancement but potentiates CNS depression with alcohol, risking sedation or respiratory failure. Avoiding alcohol shows understanding of this danger, key for safety. Driving is unsafe due to drowsiness. It doesn't cure anxiety 'it's symptomatic relief. Extra doses risk dependence. Avoiding alcohol aligns with lorazepam's pharmacology, critical in anxiety management where misuse is common, making B the statement reflecting proper education.
