Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A local municipality is alerted that low doses of carbon tetrachloride have been dumped into the drinking water. A public health alert is transmitted to all residents of this town. Which of the following signs and symptoms should these residents be aware of?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A 59-year-old man with a history of depression cuts his wrists in a suicide attempt. He is brought to the local emergency department for care. He has bilateral medial 3-cm lacerations through the skin and subcutaneous tissues that will require sutures. A review of his prior medical history indicates an allergy to 2% lidocaine. The most likely explanation for this is which of the following?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Which of the following agents exerts its therapeutic effect in multiple sclerosis via potassium channel blockade?
Correct Answer: A
Rationale: Dalfampridine treats MS by blocking potassium channels in demyelinated axons, enhancing nerve conduction and improving walking ability. Exposed potassium channels in MS leak current, impairing signal propagation; dalfampridine's blockade restores function. Donepezil boosts acetylcholine for Alzheimer's. Riluzole reduces glutamate in ALS. Bromocriptine, a dopamine agonist, manages Parkinson's. Dalfampridine's unique potassium channel action directly addresses MS's neurological deficit, supported by clinical evidence, making it the correct agent here.
Question 5 of 5
An adolescent client will receive Depo-Provera as a method of birth control. She asks the nurse how long the drug will be effective. What is the best response by the nurse?
Correct Answer: D
Rationale: Depo-Provera, a progestin injection, provides contraception by inhibiting ovulation for 3 months , requiring re-administration every 12 weeks. This duration is based on its pharmacokinetic profile, ensuring reliable hormone levels. Two months underestimates, risking unprotected gaps. Six months or 1 year overestimate, reducing efficacy mid-cycle. The nurse's accurate response (D) educates the client on timing, ensuring adherence and preventing unintended pregnancy, aligning with clinical standards for injectable contraceptives.
