Question 1 of 5
A nurse is caring for a client who started haloperidol five days ago and is experiencing neuroleptic malignant syndrome. Which of the following prescriptions should the nurse anticipate administering?
Correct Answer: C
Rationale: The correct answer is C: Bromocriptine. Bromocriptine is used to treat neuroleptic malignant syndrome, a rare but serious side effect of antipsychotic medications like haloperidol. It works by increasing dopamine levels in the brain, helping to alleviate symptoms of muscle rigidity, fever, and altered mental status associated with neuroleptic malignant syndrome. Benztropine (
Choice
A) is an anticholinergic medication used to treat extrapyramidal symptoms, not neuroleptic malignant syndrome. Naloxone (
Choice
B) is used to reverse opioid overdose. Diphenhydramine (
Choice
D) is an antihistamine and not indicated for neuroleptic malignant syndrome.
Question 2 of 5
A nurse is assessing a client who has received oxycodone. The nurse notes that the client's respiratory rate is 8/min. The nurse should identify that which of the following is the pathophysiology for the client's respiratory rate?
Correct Answer: C
Rationale:
Correct Answer: C - Oxycodone causes central nervous system depression.
Rationale: Oxycodone is an opioid analgesic that acts on the central nervous system to provide pain relief. One of the common side effects of opioids is respiratory depression, which can lead to a decreased respiratory rate. This occurs because opioids suppress the activity of the brainstem respiratory centers, leading to decreased drive to breathe and ultimately slowing down the respiratory rate.
Therefore, in this scenario, the client's low respiratory rate of 8/min is likely due to the central nervous system depression caused by oxycodone.
Summary of Incorrect
Choices:
A: Oxycodone blocking the sodium channel suspending nerve conduction is not the mechanism behind the respiratory depression seen with opioids.
B: Oxycodone promoting vasodilation of cranial arteries is not related to the respiratory depression caused by opioids.
D: Oxycodone inhibiting prostaglandin synthesis is not the mechanism responsible for the respiratory
Question 3 of 5
A nurse is caring for a client who is receiving ondansetron IV. Which of the following findings is an indication that the ondansetron is effective?
Correct Answer: A
Rationale: The correct answer is A: Decreased nausea. Ondansetron is an antiemetic medication used to treat nausea and vomiting.
Therefore, if the client is receiving ondansetron IV and their nausea is decreased, it indicates that the medication is effective in managing their symptoms. Reduced dizziness (
B) and absence of peripheral neuropathy (
D) are not direct indicators of ondansetron effectiveness. Increased urinary output (
C) is not related to the medication's mechanism of action.
Question 4 of 5
A nurse is caring for a client who has received propofol during a colonoscopy. The nurse should monitor for which of the following as an adverse effect of the medication?
Correct Answer: B
Rationale: The correct answer is B: Decrease in respiratory rate. Propofol is a sedative-hypnotic medication that can cause respiratory depression as a side effect. This occurs due to its central nervous system depressant effects, leading to a decrease in the drive to breathe. Monitoring for a decrease in respiratory rate is crucial to prevent respiratory compromise or failure. The other options are incorrect because propofol does not typically cause an increase in heart rate (
A), bowel function (
C), or body temperature (
D) as its primary adverse effects.
Question 5 of 5
A nurse is providing teaching to a client who has a new prescription for carbamazepine for the treatment of seizures. The nurse should instruct the client to monitor for which of the following adverse effects?
Correct Answer: A
Rationale: The correct answer is A: Blurred vision. Carbamazepine is known to cause visual disturbances, including blurred vision, diplopia, and nystagmus. The nurse should instruct the client to monitor for any changes in vision and report them to their healthcare provider. Insomnia (
B) is not a common adverse effect of carbamazepine. Metallic taste (
C) is associated with some medications but not typically with carbamazepine. Tachypnea (
D) refers to rapid breathing and is not a common adverse effect of carbamazepine.
