Question 1 of 5
Regarding drugs used in the treatment of status epilepsy:
Correct Answer: D
Rationale: Phenytoin controls status epilepticus via anticonvulsant action, not sedation, so that's false. It precipitates in dextrose, only saline-compatible, making that false. Diazepam's effect is short-lived, not long-lasting, so that's incorrect. Phenobarbitone commonly causes respiratory depression, a true statement, due to CNS suppression. Phenytoin's rate is 50 mg/min max. This side effect limits phenobarbitone's use, requiring ventilatory support in status management.
Question 2 of 5
Orthostatic hypotension is a common side e昀昀ect in which of these drugs (select all that apply)?
Correct Answer: A
Rationale: Orthostatic hypotension is a common side effect seen in ACE Inhibitors, Beta Blockers, and Calcium Channel Blockers.
Question 3 of 5
The nurse is preparing to give a potassium supplement. Which laboratory test should be checked before the patient receives a dose of potassium?
Correct Answer: B
Rationale: Before administering a potassium supplement to a patient, it is crucial to check the patient's serum potassium level. This is because if the serum potassium level is already elevated or within the high end of the normal range, giving additional potassium could lead to hyperkalemia, which can be life-threatening. Conversely, if the serum potassium level is low (hypokalemia), then administering potassium supplementation may be necessary to correct the deficiency. Monitoring the serum potassium level helps ensure safe and effective treatment with potassium supplements. It is a critical part of assessing the patient's electrolyte balance and overall health status.
Question 4 of 5
The nurse has completed medication education with the patient who is receiving lithium (Eskalith). What is the priority patient outcome?
Correct Answer: B
Rationale: Lithium toxicity (e.g., tremors, confusion) at narrow therapeutic range (0.6-1.2) is life-threatening-knowing signs (e.g., nausea) and prevention (e.g., hydration) is priority, per safety. Work, ADLs, and mood stability follow but aren't immediate risks. Toxicity awareness saves lives, per education.
Question 5 of 5
What is true about food and drug precautions? Select all that apply.
Correct Answer: A
Rationale: A. You must limit certain types of food or concurrent administration of certain types of drugs: Some foods can interact with certain medications, either reducing their effectiveness or causing potentially harmful side effects. Therefore, it may be necessary to limit or avoid specific foods when taking certain medications.
