1. When starting therapy with Atenolol, which of the following adverse effects should the nurse instruct the client to monitor?
- A. Tachycardia
- B. Hypoglycemia
- C. Bradycardia
- D. Hypertension
Correct answer: C
Rationale: Atenolol, a beta-blocker, can lead to bradycardia as an adverse effect due to its mechanism of action. The nurse should advise the client to monitor their pulse regularly, as a significant decrease may indicate bradycardia, a condition characterized by a slow heart rate.
2. A healthcare provider is reviewing the health history of a client who is starting therapy with tamoxifen. The healthcare provider should recognize that tamoxifen is contraindicated in which of the following clients?
- A. A client with a history of deep-vein thrombosis
- B. A client with a history of migraine headaches
- C. A client with a history of hypertension
- D. A client with a history of anemia
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.
3. A client in a coronary care unit is being admitted after CPR post cardiac arrest. The client is receiving IV lidocaine at 2 mg/min. When the client asks the nurse why he is receiving that medication, the nurse should explain that it has which of the following actions?
- A. Prevents dysrhythmias
- B. Slows intestinal motility
- C. Dissolves blood clots
- D. Relieves pain
Correct answer: A
Rationale: Lidocaine is administered to prevent dysrhythmias by delaying conduction in the heart and reducing the automaticity of heart tissue. This action helps stabilize the heart's electrical activity and prevent life-threatening arrhythmias post-cardiac arrest. Choices B, C, and D are incorrect as lidocaine is not used for slowing intestinal motility, dissolving blood clots, or relieving pain in this context.
4. A client has a new prescription for Prednisone. Which of the following instructions should be included in the discharge teaching?
- A. Increase your intake of potassium-rich foods.
- B. Avoid consuming grapefruit juice.
- C. Take this medication with food.
- D. Decrease your intake of sodium-rich foods.
Correct answer: A
Rationale: The correct answer is A: "Increase your intake of potassium-rich foods." Prednisone is associated with potassium depletion, making it important for clients to increase their intake of potassium-rich foods to prevent potential imbalances. Foods such as bananas, oranges, and spinach are good sources of potassium. Choice B, "Avoid consuming grapefruit juice," is not directly related to Prednisone use. Choice C, "Take this medication with food," is a general instruction for many medications but not specific to Prednisone. Choice D, "Decrease your intake of sodium-rich foods," is not directly related to Prednisone's side effects.
5. Which drug class has been found to decrease mortality if given within 8 hours of an MI due to a decrease in cardiac workload?
- A. Antiplatelets
- B. Beta-adrenergic blockers
- C. ACE inhibitors
- D. Calcium channel blockers
Correct answer: B
Rationale: Beta-adrenergic blockers have been shown to decrease mortality when administered within 8 hours of a myocardial infarction (MI). They do so by reducing cardiac workload, which helps improve outcomes post-MI. These drugs work by blocking the effects of adrenaline on the heart, leading to decreased heart rate, blood pressure, and myocardial oxygen demand, thereby protecting the heart muscle from further damage. This makes them a crucial part of the treatment regimen for acute coronary syndromes like MI.
