1. A postoperative client has a prescription for ketorolac 30mg IV q6h. Which response demonstrates that therapeutic levels of the medication have been achieved?
- A. Observe wound drainage for a change in appearance
- B. Assess the client's calves for inflammation
- C. Perform a pain assessment using a numeric scale
- D. Measure the client's intake and output
Correct answer: C
Rationale: The correct response is to perform a pain assessment using a numeric scale. Ketorolac is an NSAID prescribed for pain relief. Monitoring pain levels is crucial to evaluate the therapeutic effectiveness of the medication. Pain assessment helps determine if the medication is providing adequate pain relief, indicating that therapeutic levels have been achieved.
2. A healthcare professional prepares to administer a scheduled dose of labetalol by mouth to a client with hypertension. The client's heart rate is 48 beats/min, respirations are 16 breaths/min, and blood pressure is 150/90 mmHg.
- A. Administer the dose and monitor the client's blood pressure regularly
- B. Apply a telemetry monitor before administering the dose
- C. Assess for orthostatic hypotension before administering the dose
- D. Withhold the scheduled dose and notify the healthcare provider
Correct answer: D
Rationale: The client's low heart rate of 48 beats/min indicates bradycardia, a potential side effect of labetalol. Administering the dose in this case could further lower the heart rate, potentially causing adverse effects. Therefore, it is crucial to withhold the scheduled dose and notify the healthcare provider for further assessment and guidance. Choice A is incorrect because administering the dose without addressing the bradycardia can exacerbate the condition. Choice B is not relevant in this situation as telemetry monitoring is not the priority. Choice C is also not the priority in this case, as the focus should be on the client's bradycardia and the potential adverse effects of administering labetalol.
3. A client whose seizure disorder has been managed with phenytoin is admitted to the emergency department with status epilepticus. Which drug should the practical nurse anticipate being prescribed for administration to treat these seizures?
- A. Phenytoin
- B. Diazepam
- C. Phenobarbital
- D. Carbamazepine
Correct answer: B
Rationale: In the management of status epilepticus, which is a life-threatening condition of prolonged seizures, rapid intervention is crucial. Diazepam is the drug of choice for treating status epilepticus due to its fast onset of action and effectiveness in stopping seizures. It acts by enhancing the inhibitory neurotransmitter GABA to suppress seizure activity quickly. Phenytoin, although used for long-term seizure control, has a slower onset of action and is not the first-line medication for managing status epilepticus.
4. The client is receiving vancomycin, and the nurse plans to draw blood for a peak and trough to determine... the best timing for these levels?
- A. Midway through administration of the IV dose and 30 minutes before the next
- B. Two hours after completion of the IV dose and 30 minutes before the next
- C. Two hours after completion of the IV dose and one hour before the next
- D. Immediately after completion of the IV dose and 30 minutes before
Correct answer: B
Rationale: To accurately determine peak and trough levels of vancomycin, blood should be drawn two hours after the completion of the IV dose and 30 minutes before the next dose. This timing allows for appropriate assessment of the drug levels in the body, ensuring accurate monitoring of therapeutic and toxic concentrations. Choice A is incorrect as drawing blood midway through administration does not provide an accurate peak level. Choice C is incorrect as drawing blood one hour before the next dose does not represent the trough level. Choice D is incorrect because drawing blood immediately after completion of the IV dose does not allow enough time for the drug to reach peak levels.
5. A client with severe rheumatoid arthritis is prescribed methotrexate. The nurse should monitor the client for which potential adverse effect?
- A. Bone marrow suppression
- B. Increased risk of infection
- C. Liver toxicity
- D. Kidney stones
Correct answer: A
Rationale: The correct answer is A: Bone marrow suppression. Methotrexate, commonly used in rheumatoid arthritis, can lead to bone marrow suppression, reducing the production of blood cells and increasing the risk of infection. Monitoring for signs of anemia, leukopenia, and thrombocytopenia is crucial to detect bone marrow suppression early and prevent complications. Choices B, C, and D are incorrect because while methotrexate can increase the risk of infection, liver toxicity, and kidney issues, the primary concern and most significant adverse effect to monitor for is bone marrow suppression due to its impact on blood cell production.
