1. What is the therapeutic use of Phenytoin?

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

2. An adolescent client has a new prescription for Clomipramine for OCD. Which of the following instructions should the nurse include to minimize an adverse effect of this medication?

Correct answer: A

Rationale: To minimize the adverse effect of photophobia associated with Clomipramine, the client should be advised to wear sunglasses when outdoors. Clomipramine is a tricyclic antidepressant (TCA) known to cause anticholinergic effects like photophobia, which can be reduced by protecting the eyes with sunglasses when exposed to bright light. Choices B, C, and D are incorrect because checking temperature daily, taking the medication in the morning, and adding extra calories to the diet are not specifically related to minimizing the adverse effect of photophobia caused by Clomipramine.

3. Which of the following medications is a bronchodilator?

Correct answer: A

Rationale: Albuterol is classified as a bronchodilator, which is commonly used to treat conditions like asthma by relaxing the muscles in the airways and increasing airflow to the lungs. Omeprazole is a proton pump inhibitor used to reduce stomach acid production, while ondansetron is an anti-nausea medication, and senna is a laxative.

4. A healthcare provider is preparing to administer an Opioid agonist to a client who has acute pain. Which of the following complications should the provider monitor?

Correct answer: A

Rationale: The correct answer is urinary retention. Opioid agonists like morphine can suppress the awareness of bladder fullness, leading to urinary retention. This complication can result in significant discomfort and potential urinary tract issues if not promptly addressed. Tachypnea (increased respiratory rate) is a common side effect of opioids but is not a specific complication related to urinary retention. Hypertension is not typically associated with opioid agonists and is more commonly seen with opioid antagonists. An irritating cough is not a known complication of opioid agonists and is not directly related to the effect opioids have on the urinary system.

5. A client has a prescription for Nitroglycerin, and a nurse is providing teaching. Which of the following instructions should the nurse include?

Correct answer: B

Rationale: The correct instruction for taking Nitroglycerin is to take one tablet at the onset of chest pain, then repeat every 5 minutes for up to three doses. Option A is incorrect because taking a tablet every 15 minutes until pain is relieved may lead to delayed intervention. Option C is incorrect as taking Nitroglycerin at bedtime is not indicated for chest pain. Option D is incorrect as Nitroglycerin should be taken sublingually at the onset of chest pain, not on an empty stomach.
