Nursing Elites

1. How can the nurse best explain the difference between angina and a myocardial infarction to a client presenting with severe chest pain?

• A. “Angina usually resolves with rest, and is rarely fatal, while a myocardial infarction necessitates immediate treatment and can be life-threatening.”
• B. “There is a clear distinction between the two. You will receive treatment based on the diagnosis of a myocardial infarction.”
• C. “Both conditions result from a clot obstructing the coronary arteries. Angina occurs with the blockage of a small vessel, whereas a myocardial infarction occurs with a blockage of a large vessel.”
• D. “Angina may not cause as intense chest pain, whereas a myocardial infarction always presents with severe chest pain.”

Correct answer: A

Rationale: When educating a client about the differences between angina and a myocardial infarction, it is crucial to emphasize key distinguishing factors. Angina typically improves with rest and is not usually life-threatening, whereas a myocardial infarction requires urgent intervention as it can be life-threatening. This explanation helps the client understand the urgency and severity associated with a myocardial infarction compared to angina.

2. A healthcare professional is preparing to administer dextrose 5% in water (D5W) 750 mL IV to infuse over 6 hr. How many mL/hr should the IV pump be set to deliver?

• A. 125 mL/hr
• B. 100 mL/hr
• C. 150 mL/hr
• D. 200 mL/hr

Correct answer: A

Rationale: To calculate the flow rate, divide the total volume by the total time: 750 mL / 6 hr = 125 mL/hr. Therefore, the IV pump should be set to deliver 125 mL/hr to infuse D5W 750 mL over 6 hours. Choice B (100 mL/hr) is incorrect because it does not accurately divide the total volume by the total time. Choice C (150 mL/hr) and Choice D (200 mL/hr) are incorrect as they are not the correct flow rates needed to infuse the D5W solution over the specified time period.

3. Which of the following drugs is associated with the reaction of Cinchonism?

• A. Valproic acid
• B. Quinidine
• C. Isoniazid
• D. Ethosuximide

Correct answer: B

Rationale: Cinchonism is associated with Quinidine, not Valproic acid, Isoniazid, or Ethosuximide. Cinchonism is characterized by symptoms such as tinnitus, dizziness, and headaches. Quinidine, being an antiarrhythmic agent, can lead to this condition as a side effect.

4. A client with cancer is prescribed methotrexate. Which supplement should the healthcare provider recommend to reduce the risk of methotrexate toxicity?

• A. Folic acid
• B. Magnesium
• C. Vitamin D
• D. Iron

Correct answer: A

Rationale: The correct answer is folic acid. Methotrexate is a folic acid antagonist, and supplementing with folic acid can help reduce the risk of methotrexate toxicity. Folic acid supplementation is commonly recommended to counteract the effects of methotrexate on folate metabolism. Magnesium, Vitamin D, and Iron are not specifically indicated to reduce the risk of methotrexate toxicity and therefore are incorrect choices in this scenario.

5. 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.
