While reviewing a client's medical history, a healthcare professional notes a prescription for Digoxin. Which of the following findings is a manifestation of Digoxin toxicity?
- A. Elevated blood pressure
- B. Bradycardia
- C. Yellow-tinged vision
- D. Ringing in the ears
Correct Answer: C
Rationale: Yellow-tinged vision is a visual disturbance associated with Digoxin toxicity, often accompanied by other symptoms like nausea, vomiting, and confusion. Bradycardia is a common therapeutic effect of Digoxin, while elevated blood pressure and ringing in the ears are not typically associated with Digoxin toxicity. Therefore, the correct answer is yellow-tinged vision as a manifestation of Digoxin toxicity.

A provider prescribes phenobarbital for a client who has a seizure disorder. The medication has a long half-life of 4 days. How many times per day should the nurse expect to administer this medication?
- A. One
- B. Two
- C. Three
- D. Four
Correct Answer: A
Rationale: Phenobarbital has a long half-life of 4 days, meaning it remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should expect to administer phenobarbital once a day to maintain therapeutic levels and effectiveness. Administering it more than once a day would lead to unnecessary dosing and potential adverse effects as the medication remains active in the body for an extended period.
A client is being discharged with a new prescription for Clopidogrel. Which of the following instructions should the nurse include?
- A. Avoid taking aspirin while on this medication.
- B. Take this medication with food.
- C. Avoid eating foods high in potassium.
- D. Take this medication at bedtime.
Correct Answer: A
Rationale: The correct instruction for a client prescribed Clopidogrel is to avoid taking aspirin while on this medication. Clopidogrel is an antiplatelet medication that can increase the risk of bleeding. Aspirin and other NSAIDs can potentiate the risk of bleeding, so they should be avoided while taking Clopidogrel to prevent adverse effects. Choices B, C, and D are incorrect because Clopidogrel does not need to be taken with food, there is no specific dietary restriction related to potassium, and the timing of administration (bedtime) is not a critical instruction for this medication.
A client has a new prescription for Digoxin to treat heart failure. Which of the following instructions should the nurse include in the teaching?
- A. Contact the provider if the heart rate is less than 60/min.
- B. Check the pulse rate for 30 seconds and multiply the result by 2.
- C. Increase the intake of sodium.
- D. Take with food if nausea occurs.
Correct Answer: A
Rationale: The correct answer is A. It is crucial for clients on Digoxin to monitor their heart rate. A heart rate less than 60/min can indicate bradycardia, a potential side effect of Digoxin. Therefore, the client should be instructed to contact the provider if their heart rate is less than 60/min to prevent complications and receive appropriate management. Choices B, C, and D are incorrect. Checking the pulse rate for 30 seconds and multiplying by 2 is not specific to Digoxin administration. Increasing sodium intake is contraindicated as Digoxin can lead to sodium retention. Taking Digoxin with food if nausea occurs is not recommended as it may affect the drug's absorption.
A client has a new prescription for Clopidogrel. Which of the following instructions should the nurse include?
- A. Take this medication with food.
- B. Avoid taking aspirin while on this medication.
- C. Avoid eating foods high in potassium.
- D. Take this medication at bedtime.
Correct Answer: B
Rationale: When a client is prescribed Clopidogrel, an antiplatelet medication, the nurse should instruct them to avoid taking aspirin or other NSAIDs. This is because both medications can increase the risk of bleeding when taken together, potentially leading to serious health complications. Therefore, it is crucial for the client to follow this instruction to ensure their safety and well-being while on Clopidogrel. Choices A, C, and D are incorrect because taking Clopidogrel with food, avoiding foods high in potassium, or taking the medication at bedtime are not specific instructions related to the safe use of Clopidogrel and do not address the potential interaction with aspirin, which is essential for the client's well-being.
A client is being taught about Terbutaline. Which statement by the client indicates understanding of the teaching?
- A. This medication will stop my contractions.
- B. This medication will prevent vaginal bleeding.
- C. This medication will promote blood flow to my baby.
- D. This medication will increase my prostaglandin production.
Correct Answer: A
Rationale: The correct answer is A. Terbutaline works by blocking beta2-adrenergic receptors, leading to uterine smooth muscle relaxation and stopping contractions. Therefore, the client demonstrating understanding by recognizing that the medication will stop contractions is the most accurate response. Choices B, C, and D are incorrect because Terbutaline is primarily used to inhibit contractions in preterm labor, not prevent vaginal bleeding, promote blood flow to the baby, or increase prostaglandin production.
