1. What is the therapeutic action of Phenytoin?

Correct answer: B

Rationale: Phenytoin is primarily used as an anticonvulsant to prevent and control seizures. It works by stabilizing electrical activity in the brain, making it effective in managing conditions like epilepsy. Antidiabetic medications are used to regulate blood sugar levels, mood stabilizers help manage mood disorders, and antianxiety agents are used to reduce anxiety symptoms, none of which are the primary therapeutic action of Phenytoin.

2. A healthcare professional is preparing to administer eye drops to a client. Which of the following actions should the healthcare professional take? (Select all that apply.)

Correct answer: B

Rationale: When administering eye drops, it is essential to ask the client to look up at the ceiling. This position helps prevent the drops from falling onto the cornea, ensuring that the medication is properly absorbed without causing discomfort or irritation.

3. What should you assess for in a patient who is on Valproate?

Correct answer: A

Rationale: The correct answer is A: Suicidal thoughts. When a patient is prescribed Valproate, it is crucial to assess for suicidal thoughts as it is a serious side effect associated with this medication. Valproate has been linked to an increased risk of suicidal ideation and behavior, particularly in patients with epilepsy or bipolar disorder. Monitoring for signs of depression or changes in behavior is essential to ensure patient safety and well-being. Choices B, C, and D are incorrect because while monitoring for seizures, managing bipolar disorder, and treating migraines are also important considerations when a patient is on Valproate, assessing for suicidal thoughts takes priority due to the serious nature of this potential side effect.

4. When administering Phenytoin, what should you monitor?

Correct answer: D

Rationale: When administering Phenytoin, monitoring the patient's behavior is important to assess for any changes that may indicate adverse effects. Monitoring therapeutic blood levels helps ensure the medication is within the effective range and not causing toxicity. Additionally, being vigilant for signs of Stevens-Johnson syndrome, a severe skin reaction associated with Phenytoin use, is crucial for early detection and intervention. Therefore, monitoring behavior, therapeutic blood levels, and for signs of Stevens-Johnson syndrome are all essential when administering Phenytoin.

5. A healthcare provider is providing discharge instructions to a client who is prescribed Enalapril. Which of the following adverse effects should the healthcare provider instruct the client to monitor?

Correct answer: A

Rationale: A persistent dry cough is a common adverse effect of Enalapril, an ACE inhibitor. This cough is a result of increased bradykinin levels due to ACE inhibition. The client should be educated to monitor for a dry cough and notify the healthcare provider if it occurs, as it may indicate the need for a medication adjustment. Choices B, C, and D are incorrect because weight gain, diarrhea, and nausea are not commonly associated adverse effects of Enalapril.
