ATI Pharmacology Proctored Exam
1. A healthcare professional is preparing to administer a transfusion of 300 mL of pooled platelets for a client with severe Thrombocytopenia. How should the healthcare professional plan to administer the transfusion over which of the following time frames?
- A. Within 30 minutes/unit
- B. Within 60 minutes/unit
- C. Within 2 hours/unit
- D. Within 4 hours/unit
Correct answer: A
Rationale: Platelets are fragile components that must be administered promptly to minimize the risk of clumping. The correct administration time for platelets is within 15 to 30 minutes per unit to maintain their therapeutic effectiveness and reduce adverse effects. Administering platelets over longer time frames can lead to decreased efficacy and potential harm to the patient. Therefore, the correct answer is to administer the 300 mL of pooled platelets within 30 minutes per unit.
2. A hospitalized client receiving IV heparin for a deep-vein thrombosis begins vomiting blood. After the heparin has been stopped, which of the following medications should the nurse prepare to administer?
- A. Vitamin K1
- B. Atropine
- C. Protamine
- D. Calcium gluconate
Correct answer: C
Rationale: In this scenario, the client is experiencing a serious complication of heparin therapy, likely due to heparin-induced thrombocytopenia. Protamine is the antidote for heparin and can reverse its anticoagulant effects. It is essential to administer protamine promptly to counteract the effects of heparin and manage the bleeding. Vitamin K1 is used to reverse the effects of warfarin, not heparin. Atropine is used to treat bradycardia or some types of poisoning. Calcium gluconate is used to manage hyperkalemia or calcium channel blocker toxicity, not to reverse heparin's effects.
3. A client with a history of migraine headaches is starting prophylaxis therapy with Propranolol. Which of the following findings in the client history should be reported to the provider by the nurse?
- A. The client had a prior myocardial infarction.
- B. The client takes warfarin for atrial fibrillation.
- C. The client takes an SSRI for depression.
- D. An ECG indicates a first-degree heart block.
Correct answer: D
Rationale: Propranolol is contraindicated in clients with a first-degree heart block due to its negative chronotropic properties that can further slow the heart rate. This can worsen conduction through the atrioventricular node, potentially leading to heart block progression. Therefore, the nurse should report the finding of a first-degree heart block to the provider before initiating Propranolol therapy. Choices A, B, and C are not contraindications for Propranolol therapy. A prior myocardial infarction, taking warfarin for atrial fibrillation, or using an SSRI for depression do not directly impact the initiation of Propranolol therapy in a client with a history of migraine headaches.
4. When teaching a client with a new prescription for nitroglycerin patches, which of the following instructions should the nurse include?
- A. Apply the patch at the same time every day.
- B. Rotate the application site daily.
- C. Remove the patch for 12 hours each day.
- D. Cut the patch in half if needed.
Correct answer: B
Rationale: The correct instruction for a client with a new prescription for nitroglycerin patches is to rotate the application site daily. This is important to prevent skin irritation and ensure optimal absorption of the medication. Applying the patch at the same time every day (Choice A) is not necessary for nitroglycerin patches. Removing the patch for 12 hours each day (Choice C) would disrupt the continuous delivery of medication. Cutting the patch in half (Choice D) can alter the dose and is not recommended unless directed by a healthcare provider.
5. A client is receiving treatment with methotrexate. Which of the following supplements should the nurse instruct the client to take?
- A. Folic acid
- B. Vitamin D
- C. Calcium
- D. Iron
Correct answer: A
Rationale: The nurse should instruct the client to take folic acid when receiving treatment with methotrexate to reduce the risk of methotrexate toxicity. Methotrexate acts as a folic acid antagonist, leading to folic acid deficiency, which can be counteracted by supplementing with folic acid. Vitamin D, calcium, and iron are not specifically recommended to counteract methotrexate effects and do not play a significant role in mitigating methotrexate toxicity.
