ATI Pharmacology Proctored Exam

Correct Answer: A

Rationale: Phenobarbital has a long half-life of 4 days, meaning it remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should expect to administer phenobarbital once a day to maintain therapeutic levels and effectiveness. Administering it more than once a day would lead to unnecessary dosing and potential adverse effects as the medication remains active in the body for an extended period.

Correct Answer: D

Rationale: Ketamine can produce psychological effects like hallucinations. Patients with schizophrenia may be more prone to experiencing exacerbation of their symptoms when exposed to Ketamine due to its potential to worsen psychotic symptoms. Therefore, schizophrenia can be a contraindication for the use of Ketamine as an anesthetic. Peptic ulcer disease, breast cancer, and diabetes mellitus are not contraindications for the use of Ketamine.

Correct Answer: B

Rationale: The correct answer is B: Neurotoxicity. Vincristine is known to cause neurotoxicity as an adverse effect due to its impact on the nervous system. Monitoring for symptoms such as peripheral neuropathy, muscle weakness, and tingling sensations is crucial. Choices A, C, and D are incorrect because hyperkalemia, neutropenia, and bradycardia are not typically associated with vincristine therapy.

Correct Answer: B

Rationale: The correct answer is B: 'Another nurse should listen to the phone call.' When taking a telephone prescription, having another nurse listen to the phone call is essential to prevent errors in communication. This process helps ensure accuracy and reduces the risk of misinterpretation. Choice A is incorrect because entering the prescription into the client's medical record is not related to verifying the accuracy of the telephone prescription. Choice C is incorrect as the provider clarifying the prescription upon signing the health record doesn't address the immediate need for verification during the phone call. Choice D is incorrect because the 'read back' is a crucial step in confirming the accuracy of all prescriptions, regardless of whether they are one-time or recurring.

Correct Answer: C

Rationale: Atenolol is a beta-blocker that works by slowing down the heart rate. An adverse effect of atenolol is bradycardia, characterized by a slower than normal heart rate. The nurse should instruct the client to monitor for signs of bradycardia, such as a slow heart rate, while taking atenolol. Therefore, the correct answer is to monitor for bradycardia. Tachycardia (Choice A) is not an expected adverse effect of atenolol as it actually reduces heart rate. Hypoglycemia (Choice B) is not a typical adverse effect of atenolol. Hypertension (Choice D) is not an adverse effect of atenolol, as atenolol is commonly used to manage hypertension.
