1. A healthcare provider is caring for a client who is prescribed Furosemide. Which of the following laboratory values should the healthcare provider monitor?
- A. Serum potassium
- B. Serum calcium
- C. Serum sodium
- D. Serum magnesium
Correct answer: A
Rationale: Furosemide is a loop diuretic that can cause hypokalemia (low potassium levels) due to increased potassium excretion in the urine. Monitoring serum potassium levels is crucial to prevent complications such as cardiac arrhythmias. Therefore, the healthcare provider should closely monitor the client's serum potassium levels when they are prescribed Furosemide. While monitoring other electrolytes like sodium and magnesium may also be important in certain situations, the priority for a client prescribed Furosemide is to monitor serum potassium levels due to the risk of hypokalemia.
2. Which of the following drugs is associated with Stevens-Johnson syndrome?
- A. Valproic acid
- B. Quinidine
- C. Isoniazid
- D. Ethosuximide
Correct answer: D
Rationale: Stevens-Johnson syndrome is a severe skin reaction that can be associated with Ethosuximide.
3. A client has a new prescription for Alteplase. Which of the following actions should the nurse plan to take?
- A. Administer the medication within 4 hours of the onset of symptoms.
- B. Reconstitute the medication with sterile saline.
- C. Administer heparin concurrently with the Alteplase infusion.
- D. Monitor for changes in level of consciousness.
Correct answer: D
Rationale: Alteplase is a thrombolytic agent used to dissolve blood clots. Patients receiving Alteplase are at risk for bleeding complications, including intracranial bleeding. Monitoring for changes in the level of consciousness is crucial as it can indicate early signs of bleeding, such as increased intracranial pressure. This rapid assessment allows for timely intervention and prevention of further complications. Choices A, B, and C are incorrect. Administering Alteplase within 4 hours of symptom onset is related to the time-sensitive nature of thrombolytic therapy for conditions like acute myocardial infarction or ischemic stroke. Reconstituting Alteplase with sterile saline is a correct step in preparing the medication for administration. Administering heparin concurrently with Alteplase is generally avoided due to the increased risk of bleeding.
4. A healthcare provider is reviewing the health care record of a client who reports urinary incontinence and asks about a prescription for Oxybutynin. The healthcare provider should recognize that Oxybutynin is contraindicated in the presence of which of the following conditions?
- A. Bursitis
- B. Sinusitis
- C. Depression
- D. Glaucoma
Correct answer: D
Rationale: Oxybutynin is an anticholinergic medication that can increase intraocular pressure. It is contraindicated in clients with glaucoma due to the potential to worsen the condition by further elevating intraocular pressure, leading to harm. Choosing option D, Glaucoma, as the correct answer is crucial for the client's safety and to prevent exacerbation of their eye condition. Options A, B, and C are not contraindications for Oxybutynin use and are unrelated to the pharmacological effects of this medication.
5. A healthcare provider is planning to administer Ciprofloxacin IV to a client who has cystitis. Which of the following actions should the healthcare provider take?
- A. Administer a concentrated solution.
- B. Infuse the medication over 60 min.
- C. Infuse the solution through the primary IV fluid tubing.
- D. Choose a small peripheral vein for administration.
Correct answer: B
Rationale: Ciprofloxacin should be infused over 60 minutes to minimize vein irritation and reduce the risk of adverse effects. Administering a concentrated solution can lead to vein irritation and potential complications. Infusing the solution through the primary IV fluid tubing can cause incompatibility issues. Choosing a small peripheral vein may not be suitable for administering Ciprofloxacin, which should be infused through a larger vein to prevent vein irritation and ensure a proper dilution of the medication.
