1. What is the therapeutic use of metformin?

• A. Lower blood pressure
• B. Diminish seizure activity
• C. The maintenance of a person's blood glucose levels
• D. Increase heart rate and decrease gastrointestinal secretions

Correct Answer: C

Rationale: Metformin is commonly prescribed to manage and control blood glucose levels in individuals with diabetes. It helps in reducing the amount of glucose produced by the liver and improves the body's response to insulin, thereby aiding in the regulation of blood sugar levels. It is not used to lower blood pressure, diminish seizure activity, increase heart rate, or decrease gastrointestinal secretions.

2. When administering a Serotonin Antagonist, what is important to monitor for?

• A. Intake and output
• B. Mental status changes
• C. Respiratory rate
• D. Anorexia

Correct Answer: B

Rationale: When administering a Serotonin Antagonist, monitoring mental status changes is crucial. Serotonin Antagonists can affect neurological function, potentially leading to alterations in mental status. It is essential to assess for any changes in behavior, mood, or cognition to ensure patient safety and prompt intervention if needed.

3. Why is it important to monitor ins and outs in patients using ACE inhibitors?

• A. To assess for renal impairment
• B. To ensure the patient is receiving adequate fluid intake
• C. To assess the patient for potential heart failure
• D. To assess for NSAID use

Correct Answer: A

Rationale: It is crucial to monitor ins and outs in patients using ACE inhibitors to assess for renal impairment. ACE inhibitors can affect renal function, potentially leading to renal impairment. Monitoring the patient's fluid balance helps in early recognition of any renal issues and allows for timely interventions to prevent complications.

4. What is the therapeutic use of Phenytoin?

• A. Replacement in hypothyroidism to restore normal hormonal balance
• B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
• C. Diminished seizure activity, termination of ventricular arrhythmias
• D. Prevention of thrombus formation, prevention of extension of existing thrombi

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.

5. What is a common side effect that typically occurs with the initial therapy of Nitroglycerine as a result of increased vasodilation?

• A. Abdominal cramps
• B. Calf pain
• C. Headache
• D. Blurred vision

Correct Answer: C

Rationale: Headache is a common side effect associated with the initial therapy of Nitroglycerine due to its vasodilatory properties. The vasodilation caused by Nitroglycerine leads to relaxation of blood vessels, including those in the head, which can result in headaches. This side effect is considered normal and is often transient, diminishing with continued use of the medication.
