ATI Pharmacology Proctored Exam
1. A healthcare professional is preparing to initiate IV therapy for an older adult client. Which of the following actions should the professional plan to take?
- A. Use an electric shaver to remove excess hair on the extremity.
- B. Select the antecubital area to insert the IV catheter.
- C. Distend the veins by using a blood pressure cuff.
- D. Instruct the client to keep the extremity still during the procedure.
Correct answer: C
Rationale: Distending the veins using a blood pressure cuff is essential for facilitating visualization and access to the veins during IV catheter insertion. This technique helps healthcare professionals identify suitable veins, reducing the risk of complications like infiltration or hematoma formation. Using an electric shaver to remove hair on the extremity (Choice A) may increase the risk of micro-cuts and introduce infection. Selecting the antecubital area (Choice B) may not always be appropriate, as vein condition and accessibility vary among older adult clients. Instructing the client to keep the extremity still (Choice D) is important but is not directly related to preparing for IV therapy.
2. 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.
3. A provider prescribes phenobarbital for a client who has a seizure disorder. The medication has a long half-life of 4 days. How many times per day should the nurse expect to administer this medication?
- A. One
- B. Two
- C. Three
- D. Four
Correct answer: A
Rationale: Phenobarbital, with a long half-life of 4 days, remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should administer phenobarbital once a day to maintain a consistent therapeutic effect without the need for multiple daily doses. Administering the medication more than once a day would not be necessary and could increase the risk of side effects or toxicity. Therefore, the correct answer is to administer phenobarbital once a day.
4. A client has a new prescription for Metformin. Which of the following adverse effects of Metformin should the nurse instruct the client to report to the provider?
- A. Somnolence
- B. Constipation
- C. Fluid retention
- D. Weight gain
Correct answer: A
Rationale: The correct answer is A: Somnolence. Somnolence can indicate lactic acidosis, a rare but serious adverse effect of Metformin. Lactic acidosis is manifested by extreme drowsiness, hyperventilation, and muscle pain. Clients should be instructed to report these symptoms to their healthcare provider promptly to prevent further complications.
5. A client has been prescribed a calcium channel blocker for angina. The nurse knows this medication should NOT be used with caution in combination with which drug classes?
- A. NSAIDs
- B. Cardiac glycosides
- C. Beta blockers
- D. None of the above
Correct answer: C
Rationale: Calcium channel blockers and beta blockers should be used with caution together because they can both suppress heart function, potentially leading to bradycardia, heart block, or heart failure. NSAIDs and cardiac glycosides do not have significant interactions with calcium channel blockers in the same way, so they are not typically a cause for concern when combined.
