ATI Proctored Pharmacology 2023

Correct Answer: A

Rationale: The correct instruction for the nurse to include in the discharge teaching for a client prescribed Warfarin is to 'Avoid foods high in vitamin K.' Foods high in vitamin K can decrease the effectiveness of Warfarin by interfering with its anticoagulant effects, potentially leading to blood clotting issues. It is crucial for clients on Warfarin therapy to maintain a consistent intake of vitamin K-containing foods to ensure the stability of the medication's effects. Choices B, C, and D are incorrect because taking Warfarin with food, monitoring heart rate daily, or limiting fluid intake are not directly related to optimizing the effectiveness of Warfarin therapy.

Correct Answer: B

Rationale: Corrected Rationale: Hydralazine, a vasodilator, can cause reflex tachycardia, leading to an increased heart rate. This side effect should be reported to the healthcare provider to ensure appropriate management and monitoring of the client's condition. Choice A (Orthostatic hypotension) is incorrect as Hydralazine is more likely to cause reflex tachycardia than orthostatic hypotension. Choice C (Dark-colored urine) and Choice D (Persistent cough) are unrelated to the common side effects of Hydralazine and should not be the focus of monitoring for this medication.

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.

Correct Answer: B

Rationale: When a client is prescribed Atenolol, a beta-blocker, they should monitor their heart rate before taking the medication. It is crucial because if the heart rate is below 60 bpm, the client needs to contact their healthcare provider for further guidance and evaluation. Choices A, C, and D are incorrect. Atenolol does not need to be taken with a high-fat meal, does not typically cause a persistent cough, and there is no need to avoid foods high in fiber when taking this medication.

Correct Answer: B

Rationale: Protamine sulfate is the specific antidote used to reverse the effects of Heparin by binding to heparin and neutralizing its anticoagulant properties. It is crucial to administer Protamine sulfate promptly in cases of Heparin overdose or when immediate reversal of Heparin's effects is required to prevent bleeding complications. Atropine is not the antidote for Heparin; it is commonly used for treating bradycardia. Calcium carbonate is used to treat conditions like acid indigestion, heartburn, or calcium deficiency. Ferrous sulfate is a form of iron supplement used to treat or prevent iron deficiency anemia. None of these alternatives are antidotes for Heparin.
