Drugs for Peripheral Nervous System Questions
Question 1 of 5
Which of the following drugs would be useful to treat the patient's condition of repeated head jerking, blinking, and grimacing?
Correct Answer: B
Rationale: The correct answer is B: Aripiprazole. This drug is an atypical antipsychotic that can be used to treat symptoms of Tourette's syndrome, such as repeated head jerking, blinking, and grimacing. Aripiprazole works by modulating dopamine and serotonin levels in the brain, helping to reduce tics and other involuntary movements. Fluoxetine (A) is an antidepressant, Clonazepam (C) is a benzodiazepine used for anxiety and seizures, and Naltrexone (D) is used for opioid and alcohol dependence. These drugs are not typically indicated for treating the symptoms described in the patient's condition.
Question 2 of 5
Which of the following cardiovascular actions most likely contributed to the therapeutic effect of morphine in the patient's disorder?
Correct Answer: D
Rationale: The correct answer is D because peripheral venous dilation reduces venous return to the heart, decreasing preload and myocardial oxygen demand. This helps in reducing workload on the heart, making it beneficial in conditions like myocardial infarction. A: Increased systolic pressure would increase cardiac workload, not beneficial in most cardiovascular disorders. B: Constriction of the renal vascular bed would reduce renal blood flow and potentially lead to renal dysfunction. C: Increased heart rate would increase myocardial oxygen demand and workload on the heart, not ideal for most cardiovascular disorders.
Question 3 of 5
Which of the following adverse effects most likely occurred in the patient who received a standard dose of morphine intramuscularly?
Correct Answer: B
Rationale: The correct answer is B: Impairment of far vision. Morphine is known to cause miosis, which is constriction of the pupil. This can lead to impaired far vision due to decreased ability to focus on distant objects. Dysphoria (A), diarrhea (C), and hypertension (D) are potential adverse effects of morphine, but impairment of far vision is more commonly associated with its use. Dysphoria is a mood-related adverse effect, diarrhea is a gastrointestinal adverse effect, and hypertension is a cardiovascular adverse effect, none of which directly relate to the effect on vision caused by morphine.
Question 4 of 5
Which of the following analgesic drugs would be contraindicated for the patient with occlusive atherosclerotic disease of the legs?
Correct Answer: D
Rationale: The correct answer is D: Morphine. Morphine is contraindicated for patients with occlusive atherosclerotic disease of the legs because it can cause vasodilation, potentially worsening the ischemia in the affected limbs. Acetaminophen (A) is a safe option for pain relief in this patient population. Buspirone and meperidine (B) are not analgesic drugs typically used to treat pain associated with atherosclerotic disease. Zolpidem and morphine (C) are not typically contraindicated in patients with occlusive atherosclerotic disease of the legs.
Question 5 of 5
Which of the following types of drugs would be most appropriate to provide immediate relief to this patient?
Correct Answer: C
Rationale: The correct answer is C: Cocaine. Cocaine is a stimulant drug that acts quickly to provide immediate relief due to its ability to increase alertness and energy levels. This can help alleviate symptoms rapidly. Phencyclidine (A) is a dissociative drug, not typically used for immediate relief. Cannabis (B) is not known for providing immediate relief and may have varying effects. Heroin (D) is an opioid that acts more slowly and is not typically used for immediate relief. Therefore, among the choices, cocaine is the most appropriate for immediate relief.
