Nursing Elites

1. What is the therapeutic use of Phenytoin?

• A. Replacement in hypothyroidism to restore normal hormonal balance
• B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
• C. Diminished seizure activity, termination of ventricular arrhythmias
• D. Prevention of thrombus formation, prevention of extension of existing thrombi

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

2. A client is taking oral Oxycodone and Ibuprofen. The nurse should identify that an interaction between these two medications will cause which of the following findings?

• A. A decrease in serum levels of ibuprofen, possibly leading to a need for increased doses of this medication.
• B. A decrease in serum levels of oxycodone, possibly leading to a need for increased doses of this medication.
• C. An increase in the expected therapeutic effect of both medications.
• D. An increase in expected adverse effects for both medications.

Correct answer: C

Rationale: The interaction between oxycodone and ibuprofen results in an increase in the expected therapeutic effect of both medications. Oxycodone is a narcotic analgesic, while ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID). They work through different mechanisms but complement each other in pain management. When taken together, they can enhance the pain-relieving effects of each other, providing better pain relief for the client.

3. A client is taking Warfarin for atrial fibrillation. Which of the following client statements indicates a need for further teaching?

• A. I will avoid eating broccoli.
• B. I will use an electric razor to shave.
• C. I will take aspirin for headaches.
• D. I will have my blood tested regularly.

Correct answer: C

Rationale: The correct answer is C. Taking aspirin along with Warfarin can increase the risk of bleeding. Clients should be advised to avoid medications that increase the risk of bleeding when taking Warfarin to prevent complications. Choices A, B, and D are all correct statements indicating good understanding of Warfarin therapy. Avoiding foods high in Vitamin K, using an electric razor to prevent cuts that can lead to bleeding, and regular blood testing to monitor Warfarin levels are all important aspects of managing Warfarin therapy.

4. A client with increased intracranial pressure is receiving Mannitol. Which finding should the nurse report to the provider?

• A. Blood glucose 150 mg/dL
• B. Urine output 40 mL/hr
• C. Dyspnea
• D. Bilateral equal pupil size

Correct answer: C

Rationale: Dyspnea is a concerning finding in a client receiving Mannitol as it can be a manifestation of heart failure, an adverse effect of the medication. It suggests potential fluid overload or exacerbation of heart conditions, both of which require immediate attention. Reporting dyspnea promptly allows for timely evaluation and management. Blood glucose levels and urine output are important parameters to monitor but are not directly related to the administration of Mannitol for increased intracranial pressure. Bilateral equal pupil size is a normal and expected finding.

5. A client has a new prescription for levothyroxine. Which of the following instructions should the nurse include?

• A. Take this medication at bedtime.
• B. Take this medication with food.
• C. Take this medication on an empty stomach in the morning.
• D. Take this medication with an antacid.

Correct answer: C

Rationale: Levothyroxine should be taken on an empty stomach in the morning to enhance its absorption. This timing allows for optimal absorption and effectiveness of the medication. Taking it with food, at bedtime, or with an antacid may interfere with its absorption and reduce its efficacy.
