Nursing Elites

1. What does it mean when a medication has a half-life?

• A. It only lasts for 30 minutes after the medication is given
• B. How long it takes for half of the dose to be eliminated from the bloodstream
• C. It is the peak of how effective the medicine is
• D. Drug is greatly reduced before it reaches the systemic circulation

Correct answer: B

Rationale: When a medication has a half-life, it refers to the time it takes for half of the dose to be eliminated from the bloodstream. This parameter is crucial in understanding the duration of action and dosing intervals for medications in clinical practice. Choice A is incorrect as the half-life is not about how long the medication lasts but about elimination from the body. Choice C is incorrect because the half-life is not about the peak effectiveness of the medicine. Choice D is incorrect as it does not accurately define the concept of half-life.

2. A client received IV Verapamil to treat supraventricular tachycardia (SVT). The client's pulse rate is now 98/min, and blood pressure is 74/44 mm Hg. The nurse should anticipate a prescription for which of the following IV medications?

• A. Calcium gluconate
• B. Sodium bicarbonate
• C. Potassium chloride
• D. Magnesium sulfate

Correct answer: A

Rationale: In this situation, where the client's blood pressure is significantly lowered due to Verapamil administration, the nurse should anticipate a prescription for Calcium gluconate. Calcium gluconate is used to reverse severe hypotension caused by Verapamil. It should be given slowly intravenously as it counteracts the vasodilation caused by Verapamil, helping to normalize blood pressure levels. Sodium bicarbonate is not indicated for low blood pressure. Potassium chloride and magnesium sulfate are not the appropriate choices to address hypotension caused by Verapamil.

3. What finding should a nurse monitor for as an adverse effect when a client has a new prescription for Spironolactone?

• A. Hyperkalemia
• B. Hypoglycemia
• C. Hypocalcemia
• D. Hyponatremia

Correct answer: A

Rationale: The correct answer is hyperkalemia. Spironolactone is a potassium-sparing diuretic that can lead to an increase in potassium levels. Hyperkalemia can be dangerous, causing muscle weakness and cardiac dysrhythmias. Monitoring potassium levels closely is crucial when a client is on Spironolactone. Hypoglycemia (choice B) is incorrect because Spironolactone does not typically affect blood glucose levels. Hypocalcemia (choice C) and hyponatremia (choice D) are also incorrect as Spironolactone's primary impact is on potassium levels.

4. A client is being educated by a healthcare provider about managing Digoxin toxicity. Which statement by the client demonstrates an understanding of the teaching?

• A. I will take an extra dose of Digoxin if I miss one.
• B. I should notify my healthcare provider if I experience visual changes.
• C. I will stop taking Digoxin if my heart rate is below 70 bpm.
• D. I should take antacids to alleviate gastrointestinal upset.

Correct answer: B

Rationale: The correct answer is B. Visual changes, such as yellow or blurred vision, can be indicative of digoxin toxicity. It is crucial for clients to inform their healthcare provider promptly if they encounter these symptoms. Prompt medical attention can help manage potential toxicity and prevent complications. Choices A, C, and D are incorrect because taking an extra dose of Digoxin, stopping Digoxin based on heart rate alone, and using antacids for gastrointestinal upset are not appropriate actions when managing Digoxin toxicity.

5. A healthcare professional is reviewing the medical history of a client who has a new prescription for Metformin to treat type 2 diabetes. Which of the following findings should the healthcare professional report to the provider?

• A. Hemoglobin A1C of 7.5%
• B. Creatinine level of 1.2 mg/dL
• C. BUN level of 18 mg/dL
• D. Liver function tests showing AST of 50 units/L

Correct answer: D

Rationale: The correct answer is D. Elevated AST levels in liver function tests should be reported to the provider when a client is prescribed Metformin due to the potential risk of hepatotoxicity associated with the medication. Elevated Hemoglobin A1C (choice A), Creatinine level within normal range (choice B), and BUN level within normal range (choice C) are not directly concerning when initiating Metformin therapy.
