Nursing Elites

1. 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.

2. A client receiving chemotherapy reports nausea and vomiting. Which of the following medications should the nurse anticipate administering?

• A. Ondansetron
• B. Metoclopramide
• C. Promethazine
• D. Lorazepam

Correct answer: A

Rationale: The correct answer is A: Ondansetron. Ondansetron is a commonly used antiemetic for managing nausea and vomiting in clients undergoing chemotherapy. It works by blocking serotonin to reduce these symptoms effectively. Metoclopramide (choice B) is another antiemetic but is more commonly used for gastric motility disorders. Promethazine (choice C) is an antihistamine with antiemetic properties, but ondansetron is often preferred for chemotherapy-induced nausea and vomiting due to its efficacy and fewer side effects. Lorazepam (choice D) is a benzodiazepine used for anxiety and insomnia, not typically for managing nausea and vomiting in this context.

3. A client with migraine headaches is starting prophylaxis therapy with Propranolol. Which finding in the client's history should the nurse report to the provider?

• 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 first-degree heart block due to its negative inotropic and chronotropic effects. The nurse should report this finding to the provider to consider an alternative therapy to prevent potential worsening of cardiac conduction abnormalities. Choices A, B, and C are not directly contraindications to Propranolol therapy for migraine headaches and do not pose immediate risks that would require reporting to the provider.

4. A healthcare professional is preparing to administer a transfusion of 300 mL of pooled platelets for a client who has severe Thrombocytopenia. How long should the healthcare professional plan to administer the transfusion over?

• A. Within 30 min/unit
• B. Within 60 min/unit
• C. Within 2 hr/unit
• D. Within 4 hr/unit

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.

5. Which drug undergoes extensive first-pass hepatic metabolism?

• A. Heparin
• B. Insulin
• C. Propranolol
• D. Nitroglycerin

Correct answer: C

Rationale: Propranolol undergoes extensive first-pass hepatic metabolism in the liver. When administered orally, propranolol is extensively metabolized by the liver before reaching systemic circulation, leading to reduced bioavailability. This process is known as first-pass hepatic metabolism, which significantly affects the drug's effectiveness and necessitates higher oral doses compared to other routes of administration. Heparin (Choice A) is not metabolized by the liver but excreted unchanged by the kidneys. Insulin (Choice B) is a peptide hormone that is not subject to significant first-pass metabolism. Nitroglycerin (Choice D) is primarily metabolized in the blood and tissues, bypassing significant first-pass metabolism in the liver.
