ATI Pharmacology Proctored Exam
1. A client has been prescribed Valsartan. Which of the following adverse effects should the nurse monitor?
- A. Hyperkalemia
- B. Hypoglycemia
- C. Bradycardia
- D. Hypercalcemia
Correct answer: A
Rationale: Corrected Rationale: Valsartan is an angiotensin II receptor blocker (ARB) that can lead to hyperkalemia by inhibiting the action of aldosterone. Hyperkalemia is a potential adverse effect, making it essential for the nurse to closely monitor the client's potassium levels to prevent complications such as cardiac arrhythmias. Incorrect Options Rationale: - Option B, Hypoglycemia, is not a common adverse effect of Valsartan. - Option C, Bradycardia, is not typically associated with Valsartan use. - Option D, Hypercalcemia, is not a known adverse effect of Valsartan; instead, Valsartan can lead to hyperkalemia.
2. Which of the following medications is a bronchodilator?
- A. Albuterol
- B. Omeprazole
- C. Ondansetron
- D. Senna
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.
3. When reviewing a client's health record, a nurse notes a new prescription for Lisinopril 10 mg PO once daily. The nurse should identify this as which type of prescription?
- A. Single
- B. Stat
- C. Routine
- D. Standing
Correct answer: C
Rationale: A routine prescription indicates medications to be administered on a regular schedule without a termination date or a specific number of doses. In this case, Lisinopril 10 mg PO once daily falls under a routine prescription, meaning the nurse will administer this medication daily until the provider discontinues it. Choices A, B, and D are incorrect: A 'single' prescription is for a one-time dose, 'stat' prescriptions are for immediate administration, and 'standing' prescriptions are pre-authorized for administration as needed within specified parameters.
4. A client with congestive heart failure taking digoxin refused breakfast and is complaining of nausea and weakness. Which action should the nurse take first?
- A. Check the client's vital signs.
- B. Request a consult with a dietitian.
- C. Suggest that the client rests before eating the meal.
- D. Request an order for an antiemetic.
Correct answer: A
Rationale: The nurse should check the client's vital signs first because nausea and weakness can be signs of digoxin toxicity. Vital signs can provide immediate information on the client's condition and help guide further interventions. Monitoring vital signs will allow the nurse to assess for bradycardia, a common sign of digoxin toxicity. Requesting a dietitian consult (choice B) may be necessary but addressing the immediate concern of toxicity is the priority. Suggesting rest before eating (choice C) may not address the underlying issue of digoxin toxicity. Requesting an antiemetic (choice D) can be considered later but is not the initial action needed in this situation.
5. 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.
