Nursing Elites

1. The nurse is teaching a client about lifestyle changes to manage hypertension. Which dietary change should the nurse recommend?

• A. Increase intake of red meat
• B. Use salt substitutes liberally
• C. Limit sodium intake to 2 grams per day
• D. Increase intake of processed foods

Correct answer: C

Rationale: The correct answer is C: 'Limit sodium intake to 2 grams per day.' This recommendation is crucial in managing hypertension because excessive sodium intake can lead to elevated blood pressure. Reducing sodium intake helps the body regulate fluid balance and lower blood pressure. Choices A, B, and D are incorrect. Increasing red meat intake can worsen hypertension due to its high saturated fat content. Using salt substitutes liberally can also be harmful as they often contain high amounts of potassium, which can be problematic for individuals with certain health conditions. Increasing processed foods consumption is generally discouraged in hypertension management due to their high sodium content and low nutritional value.

2. The client with a history of angina pectoris reports chest pain unrelieved by nitroglycerin. Which action should the nurse take next?

• A. Administer another dose of nitroglycerin.
• B. Notify the healthcare provider immediately.
• C. Have the client lie down and rest.
• D. Encourage the client to take deep breaths.

Correct answer: B

Rationale: When a client with a history of angina pectoris reports chest pain unrelieved by nitroglycerin, it may indicate a myocardial infarction, also known as a heart attack. In this situation, the nurse should immediately notify the healthcare provider to ensure prompt evaluation and appropriate intervention. Delay in seeking medical attention for chest pain unrelieved by nitroglycerin can be life-threatening, as it might be a sign of a more serious cardiac event. Administering another dose of nitroglycerin (Choice A) without further evaluation can be risky, as the client's condition may require a different intervention. Having the client lie down and rest (Choice C) or encouraging deep breaths (Choice D) are not appropriate actions in this scenario where a more serious cardiac event needs to be ruled out.

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

• A. Avoid consuming dairy products.
• B. Take the medication on an empty stomach.
• C. Increase your intake of folic acid.
• D. Monitor for signs of hyperglycemia.

Correct answer: C

Rationale: Increasing folic acid intake is crucial when taking methotrexate because the medication can lead to folic acid deficiency. Folic acid supplementation helps counteract this deficiency and reduces the risk of adverse effects associated with methotrexate therapy. Choices A, B, and D are incorrect. Avoiding dairy products is not specifically necessary for methotrexate therapy. Methotrexate is usually taken with food to reduce gastrointestinal side effects, so taking it on an empty stomach is not recommended. Monitoring for signs of hyperglycemia is not directly related to methotrexate use.

4. A client is taking levothyroxine for hypothyroidism. Which of the following findings should indicate to the healthcare provider that the client is experiencing levothyroxine toxicity?

• A. Weight loss
• B. Insomnia
• C. Heat intolerance
• D. Dry skin

Correct answer: C

Rationale: Heat intolerance is a hallmark sign of levothyroxine toxicity. It indicates that the client may be receiving an excessive dose of levothyroxine, leading to hyperthyroid symptoms. This can happen when the dosage is too high, causing the body to have an excess of thyroid hormone. Weight loss is a common symptom of hyperthyroidism but alone does not specifically indicate levothyroxine toxicity. Insomnia can be related to hyperthyroidism but is not a specific sign of levothyroxine toxicity. Dry skin is more commonly associated with hypothyroidism rather than levothyroxine toxicity.

5. The LPN/LVN is assisting in caring for a client in the telemetry unit who is receiving an intravenous infusion of 1000 mL of 5% dextrose with 40 mEq of potassium chloride. Which occurrence observed on the cardiac monitor indicates the presence of hyperkalemia?

• A. Tall, peaked T waves
• B. ST segment depressions
• C. Shortened P-R intervals
• D. Shortening of the QRS complex

Correct answer: A

Rationale: In hyperkalemia, tall, peaked T waves are a distinct ECG finding. These T waves can be seen as a result of increased serum potassium levels, affecting the repolarization phase of the cardiac action potential. It is crucial for healthcare providers to recognize this ECG change promptly as hyperkalemia can lead to serious cardiac arrhythmias and complications. ST segment depressions, shortened P-R intervals, and shortening of the QRS complex are not typically associated with hyperkalemia. ST segment depressions are more indicative of myocardial ischemia or infarction. Shortened P-R intervals may be seen in conditions like Wolff-Parkinson-White syndrome. Shortening of the QRS complex is associated with conditions affecting the conduction system of the heart, such as bundle branch blocks.
