ATI Pharmacology Proctored Exam

Correct Answer: A

Rationale: Folic acid supplementation is crucial for clients undergoing methotrexate treatment because methotrexate functions as a folic acid antagonist. By supplementing with folic acid, the risk of methotrexate toxicity can be minimized, improving the treatment's effectiveness and safety. Vitamin D, calcium, and iron are not specifically recommended in conjunction with methotrexate therapy and may not provide the same protective benefits as folic acid.

Correct Answer: A

Rationale: Tamoxifen is contraindicated in clients with a history of thromboembolic events, such as deep-vein thrombosis, due to the increased risk of blood clots. The estrogenic effects of tamoxifen can further increase the risk of thromboembolic events, making it unsafe for individuals with a history of deep-vein thrombosis. Choice B (migraine headaches), Choice C (hypertension), and Choice D (anemia) are not contraindications for tamoxifen therapy. Migraine headaches, hypertension, and anemia do not pose the same risk of adverse effects related to blood clot formation as deep-vein thrombosis does.

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: C

Rationale: The correct answer is C: 'Decreases cravings.' Propranolol is commonly used as an adjunct medication during alcohol withdrawal to help reduce cravings for alcohol. It does not increase the risk for seizure activity, provide aversion therapy, or result in mild hypertension. By decreasing cravings, Propranolol can support the client in managing alcohol withdrawal symptoms and promoting abstinence. Therefore, it is important to educate the client on how Propranolol can help them cope with alcohol cravings effectively.

Correct Answer: A

Rationale: Platelets are fragile components that must be administered quickly to maintain their effectiveness and minimize the risk of clumping. The recommended administration time for platelets is within 15 to 30 minutes per unit. This rapid administration helps ensure the platelets remain viable and functional for the client receiving the transfusion. Therefore, the correct answer is to administer the transfusion within 30 minutes per unit. Choices B, C, and D are incorrect as they exceed the recommended administration time for platelets, which could compromise their efficacy and pose risks to the client.
