ATI Pharmacology Proctored Exam 2019
1. A client is prescribed Spironolactone. Which of the following laboratory findings should the nurse monitor and report to the provider?
- A. Sodium level of 138 mEq/L
- B. Potassium level of 5.2 mEq/L
- C. Chloride level of 100 mEq/L
- D. Calcium level of 9.5 mg/dL
Correct answer: B
Rationale: Spironolactone is a potassium-sparing diuretic, causing potassium retention, potentially leading to elevated potassium levels. A potassium level of 5.2 mEq/L is above the normal range (3.5-5.0 mEq/L), indicating hyperkalemia, a serious condition. Elevated potassium levels can lead to life-threatening cardiac arrhythmias. Monitoring and reporting high potassium levels promptly to the healthcare provider are crucial to prevent potential complications. Sodium, chloride, and calcium levels are not directly influenced by Spironolactone, making choices A, C, and D incorrect.
2. A healthcare professional is preparing to administer Haloperidol 2 mg PO every 12 hr. The available medication is haloperidol 1 mg/tablet. How many tablets should the healthcare professional administer?
- A. 1 tablet
- B. 2 tablets
- C. 3 tablets
- D. 4 tablets
Correct answer: B
Rationale: To calculate the number of tablets needed, divide the desired dose by the dose per tablet. In this case, (2 mg / 1 mg/tablet) = 2 tablets required to administer the correct dosage of Haloperidol.
3. A client with Angina Pectoris asks the nurse about the next step if they take one tablet, wait 5 minutes, but still have Anginal pain. Which response should the nurse provide?
- A. Take two more sublingual tablets at the same time.
- B. Call emergency services.
- C. Take a sustained-release nitroglycerin capsule.
- D. Wait another 5 minutes then take a second sublingual tablet.
Correct answer: B
Rationale: If anginal pain persists after taking the first tablet and waiting 5 minutes, the priority step is to call emergency services (911) and then take a second sublingual tablet. Persistent pain could indicate a myocardial infarction, and immediate medical attention is crucial. Taking two more tablets at the same time (Choice A) can lead to excessive vasodilation and hypotension. Taking a sustained-release nitroglycerin capsule (Choice C) is not appropriate for immediate relief during an acute episode. Waiting another 5 minutes and then taking a second tablet (Choice D) is not advisable in this emergency situation where prompt action is necessary.
4. A client is taking oral Oxycodone and Ibuprofen in recommended doses. The nurse should identify that an interaction between these two medications will cause which of the following findings?
- A. A decrease in serum levels of ibuprofen, possibly leading to a need for increased doses of this medication.
- B. A decrease in serum levels of oxycodone, possibly leading to a need for increased doses of this medication.
- C. An increase in the expected therapeutic effect of both medications.
- D. An increase in expected adverse effects for both medications.
Correct answer: C
Rationale: When Oxycodone, a narcotic analgesic, and Ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), are taken together, they work synergistically to enhance the pain-relieving effects of both medications. These drugs act through different mechanisms, leading to a combined analgesic effect that is more effective than when used alone. Therefore, the interaction between Oxycodone and Ibuprofen results in an increase in the expected therapeutic effect of both medications.
5. A healthcare professional is preparing to administer IV Dantrolene to a client who has developed Malignant Hyperthermia during surgery. Which of the following actions should the healthcare professional take?
- A. Dilute the medication with sterile water and administer it rapidly.
- B. Store the medication in a refrigerator until use.
- C. Administer the medication through a large-bore IV catheter.
- D. Administer the medication via an infusion pump over 60 minutes.
Correct answer: C
Rationale: Dantrolene should be administered through a large-bore IV catheter because it is highly irritating to tissues and can cause vein irritation or thrombophlebitis if administered through a small vein. Using a large-bore IV catheter helps to minimize the risk of tissue damage and ensures proper and safe administration of the medication in emergency situations like Malignant Hyperthermia. Choices A, B, and D are incorrect because diluting the medication with sterile water and administering it rapidly can lead to tissue damage, storing the medication in a refrigerator is not necessary, and administering the medication via an infusion pump over 60 minutes is not appropriate in emergency situations like Malignant Hyperthermia where rapid administration is crucial.
