1. A healthcare professional is reviewing the medication list of a client scheduled for surgery. Which of the following medications places the client at risk for increased bleeding during surgery?
- A. Warfarin
- B. Acetaminophen
- C. Ibuprofen
- D. Aspirin
Correct answer: D
Rationale: Aspirin is an anticoagulant that inhibits platelet function, increasing the risk of bleeding during surgery. It is important for the healthcare professional to identify this medication, inform the surgical team, and consider withholding it prior to surgery to reduce the risk of excessive bleeding. Warfarin is also an anticoagulant but can be managed by adjusting the dosage or monitoring INR levels. Acetaminophen and ibuprofen are not associated with increased bleeding risk as they do not affect platelet function like aspirin.
2. A client has a new prescription for Timolol. How should the nurse instruct the client to insert eye drops?
- A. Press your finger on the inside corner of your eye for 1 minute after application.
- B. Apply the eye drops directly to the cornea.
- C. Drop the prescribed amount of medication into the center of the conjunctival sac.
- D. Wipe your eyes gently with a tissue immediately after application.
Correct answer: C
Rationale: When administering eye drops, it is essential to instruct the client to drop the prescribed amount of medication into the center of the conjunctival sac. This technique helps ensure proper distribution of the medication and reduces the risk of potential adverse effects. Pressing on the inside corner of the eye is done to prevent systemic absorption, applying drops directly to the cornea can cause irritation, and wiping the eyes after application can lead to decreased effectiveness of the medication.
3. A healthcare provider is providing discharge instructions to a client who has a new prescription for Warfarin. Which of the following over-the-counter medications should the provider instruct the client to avoid?
- A. Acetaminophen
- B. Ibuprofen
- C. Diphenhydramine
- D. Loratadine
Correct answer: B
Rationale: Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can increase the risk of bleeding when taken with Warfarin due to its antiplatelet effects. The combination of Warfarin, an anticoagulant, and NSAIDs can potentiate the risk of bleeding complications. Clients on Warfarin should avoid NSAIDs like ibuprofen and opt for alternative pain relief options such as acetaminophen. Diphenhydramine and loratadine are antihistamines and are generally safe to use with Warfarin as they do not significantly increase the risk of bleeding when compared to NSAIDs like ibuprofen.
4. How is lithium typically administered?
- A. Intravenously
- B. Intramuscularly
- C. Orally
- D. Sublingually
Correct answer: C
Rationale: Lithium is typically administered orally to ensure proper absorption and distribution in the body. By taking lithium orally, it allows the medication to be absorbed through the gastrointestinal tract and distributed effectively. Intravenous and intramuscular routes are not commonly used for lithium administration as they can lead to rapid, unpredictable absorption and increase the risk of toxicity. Sublingual administration is also not the typical route for lithium, as it is usually taken orally for consistent and controlled absorption.
5. When taking Digoxin, low levels of what can cause toxicity?
- A. Potassium
- B. Calcium
- C. Sodium
- D. Magnesium
Correct answer: A
Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.
