ATI N180 Pharmacology Exam Questions
Question 1 of 5
A nurse is teaching a client with a new prescription of dantrolene (Dantrium). Which of the following information should the nurse include in the teaching about this medication?
Correct Answer: B
Rationale: The correct answer is B: This medication is used to treat malignant hyperthermia. Dantrolene is a skeletal muscle relaxant that is specifically indicated for the treatment of malignant hyperthermia, a rare but life-threatening condition triggered by certain anesthesia agents. The nurse should include this information in the teaching to ensure the client understands the purpose and importance of the medication.
Choices A, C, and D are incorrect because dantrolene is not used for preventing migraines, treating alcohol use disorder, or managing mild pain. It is crucial for the nurse to provide accurate and relevant information to the client to promote safe and effective medication use.
Question 2 of 5
The nurse is educating a client about taking a tetracycline along with an antacid. The nurse explains to the client not to take these two medications because the antacid can reduce the absorption of the tetracycline. When one drug reduces the effect of another, it is:
Correct Answer: C
Rationale: The correct answer is C: an antagonistic effect. This is because when the antacid reduces the absorption of the tetracycline, it diminishes the effectiveness of the tetracycline. This is an example of drug-drug interaction where one drug interferes with the action of another. An antagonistic effect occurs when one drug diminishes the effect of another drug. In this case, the antacid is antagonizing the tetracycline, leading to decreased absorption and potentially reducing its therapeutic benefits.
Choices A, B, and D are incorrect. A is an allergic reaction, which is an immune system response to a drug and not related to drug interactions. B is a synergistic effect, which occurs when two drugs together produce a greater effect than the sum of their individual effects, not when one drug inhibits the action of another. D states "None of the above," which is also incorrect as the scenario described clearly matches with the definition of an antagonistic effect.
Question 3 of 5
You are caring for a new client that got admitted to the unit for abdominal pain. The client takes levothyroxine (Synthroid) at home. The nurse understands that the client is taking levothyroxine (Synthroid) to treat which of the following conditions?
Correct Answer: B
Rationale: The correct answer is B: Hypothyroidism. Levothyroxine (Synthroid) is a synthetic form of thyroid hormone used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. The medication helps to restore the hormone levels in the body to normal, improving metabolism, energy levels, and overall well-being.
Choice A, hyperglycemia, is high blood sugar and is not treated with levothyroxine.
Choice C, hypokalemia, is low potassium levels and is not treated with levothyroxine.
Choice D, hypoglycemia, is low blood sugar and is not treated with levothyroxine. The key is to recognize that levothyroxine is specifically used for hypothyroidism.
Question 4 of 5
A new patient on the unit is scheduled to take two medications at 0900. Before giving the medications, the nurse goes over her medication rights and checks. Which of the following option is not included in the 10 rights of safeнами medication administration?
Correct Answer: B
Rationale: The correct answer is B: Right insurance approval. This is not included in the 10 rights of safe medication administration. The 10 rights are: Right patient, right medication, right dose, right route, right time, right reason, right documentation, right response, right to refuse, and right education. Insurance approval is not related to ensuring safe medication administration. It is important for the nurse to focus on the patient's safety and the accuracy of medication administration rather than insurance approval. The other options (A, C, and
D) are all essential components of safe medication administration as they ensure the correct medication, time, and route are used for the patient.
Question 5 of 5
A nurse administered prochlorperazine (Compazine) IV to a client two hours ago. Which of the following signs should the nurse recognize as a complication of this medication?
Correct Answer: C
Rationale: The correct answer is C: Prolonged QT interval. Prochlorperazine can cause QT interval prolongation, leading to serious cardiac arrhythmias like torsades de pointes. Monitoring the QT interval is crucial to detect this complication early. Nausea and vomiting are common side effects of prochlorperazine but not indicative of a complication. Anxiety is not typically associated with this medication. In summary, the nurse should be vigilant in monitoring for prolonged QT interval as a potential complication of prochlorperazine administration.
