1. 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.
2. A healthcare provider is providing discharge instructions to a client who is prescribed Warfarin. Which of the following dietary instructions should the provider include?
- A. Increase your intake of leafy green vegetables.
- B. Avoid foods high in vitamin K.
- C. Increase your intake of dairy products.
- D. Avoid foods high in iron.
Correct answer: B
Rationale: The correct answer is to avoid foods high in vitamin K. Vitamin K can interfere with the effectiveness of Warfarin by counteracting its anticoagulant effects. Foods high in vitamin K, such as leafy green vegetables, should be limited in the diet of individuals taking Warfarin to maintain a consistent level of the medication's effectiveness. Choices A, C, and D are incorrect as increasing intake of leafy green vegetables (choice A) and dairy products (choice C) may increase the intake of vitamin K, which is not recommended, and avoiding foods high in iron (choice D) is not directly related to Warfarin therapy.
3. A client has been prescribed Methotrexate to treat Rheumatoid Arthritis. Which of the following instructions should the nurse provide?
- A. Take this medication with food to prevent nausea.
- B. Avoid alcohol while taking this medication.
- C. Wear sunscreen when outdoors while taking this medication.
- D. Take this medication on an empty stomach.
Correct answer: B
Rationale: Methotrexate is hepatotoxic, and avoiding alcohol is crucial to prevent liver damage. However, Option A (Take this medication with food to prevent nausea) could also be correct, as Methotrexate commonly causes nausea, and taking it with food can help alleviate this side effect. However, the most important instruction is to avoid alcohol due to the risk of liver toxicity.
4. A client is taking Spironolactone. Which of the following laboratory findings should the nurse monitor and report to the provider?
- A. Sodium level of 138 mEq/L
- B. Potassium level of 5.2 mEq/L
- C. Chloride level of 100 mEq/L
- D. Calcium level of 9.5 mg/dL
Correct answer: B
Rationale: The correct answer is B: Potassium level of 5.2 mEq/L. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia (elevated potassium levels). A potassium level of 5.2 mEq/L is considered elevated and should be reported to the provider for further assessment and management to prevent potential complications. Choices A, C, and D are not directly affected by Spironolactone and do not typically require immediate reporting unless there are other underlying issues or specific instructions for those electrolytes.
5. How do ACE inhibitors work?
- A. Block the vasoconstrictor and aldosterone effects of angiotensin II at the receptor site
- B. Block stimulation of beta 1 and beta 2 at the receptor sites
- C. Block the conversion of angiotensin I to the vasoconstrictor angiotensin II
- D. None of the above
Correct answer: C
Rationale: ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, and by blocking its production, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload of the heart. Choice A is incorrect because it describes the mechanism of action of angiotensin receptor blockers (ARBs), not ACE inhibitors. Choice B is incorrect as it describes beta-blockers, not ACE inhibitors. Choice D is incorrect as ACE inhibitors do have a specific mechanism of action.
