Nursing Elites

1. A nurse is reviewing the results of an arterial blood gas analysis of a client who has chronic obstructive pulmonary disease. Which of the following results should the nurse expect?

• A. PaO2 of 95 mm Hg
• B. PaCO2 of 55 mm Hg
• C. HCO3 of 24 mEq/L
• D. pH level of 7.35

Correct answer: B

Rationale: In chronic obstructive pulmonary disease, there is impaired gas exchange, leading to retention of carbon dioxide (CO2) and subsequent respiratory acidosis. A PaCO2 of 55 mm Hg is higher than the normal range (35-45 mm Hg) and is indicative of respiratory acidosis in COPD. Choices A, C, and D are not typically associated with COPD. PaO2 may be decreased, HCO3 may be elevated to compensate for acidosis, and pH may be lower than 7.35 due to respiratory acidosis in COPD.

2. A nurse is providing discharge teaching to a client who has a new prescription for warfarin. Which of the following client statements indicates an understanding of the teaching?

• A. I will need to have my INR checked regularly while taking this medication.
• B. I should avoid eating leafy green vegetables while taking this medication.
• C. I will stop taking this medication if I experience nausea.
• D. I will avoid taking aspirin while taking this medication.

Correct answer: A

Rationale: The correct answer is A because clients taking warfarin should have their INR (International Normalized Ratio) checked regularly to monitor the medication's effectiveness and adjust the dose if needed. This monitoring helps to ensure the medication is working correctly and the client is within the therapeutic range. Choice B is incorrect because clients on warfarin should not avoid leafy green vegetables but should maintain a consistent intake. Leafy green vegetables contain vitamin K, which can affect warfarin, so it's important to maintain a consistent intake to keep INR stable. Choice C is incorrect as clients should not stop taking warfarin abruptly without consulting their healthcare provider as it can lead to serious health risks like blood clots. Choice D is incorrect because while taking warfarin, it is important to avoid unnecessary aspirin use due to an increased risk of bleeding. However, this statement does not indicate an understanding of the teaching about the need for regular INR monitoring.

3. A nurse is caring for a client who has a new prescription for metformin. Which of the following instructions should the nurse include?

• A. Take this medication on an empty stomach.
• B. You should avoid eating foods high in potassium.
• C. You should take this medication with meals to improve absorption.
• D. Take this medication before bed to prevent drowsiness.

Correct answer: C

Rationale: The correct instruction for a client prescribed metformin is to take the medication with meals to improve absorption and reduce gastrointestinal upset. Metformin is typically recommended to be taken with food to minimize side effects. Option A is incorrect as taking metformin on an empty stomach may increase the risk of gastrointestinal side effects. Option B is unrelated as metformin does not interact with potassium-rich foods. Option D is also incorrect as metformin does not cause drowsiness, so there is no need to take it before bed.

4. What is the best intervention for a patient experiencing respiratory distress?

• A. Administer oxygen
• B. Administer bronchodilators
• C. Administer IV fluids
• D. Provide chest physiotherapy

Correct answer: A

Rationale: Administering oxygen is the best intervention for a patient experiencing respiratory distress because it helps improve oxygenation and alleviate respiratory distress. Oxygen therapy is crucial in ensuring that the patient receives an adequate supply of oxygen to meet the body's demands. Administering bronchodilators (Choice B) may be beneficial in specific respiratory conditions like asthma or COPD but may not be the primary intervention in all cases of respiratory distress. Administering IV fluids (Choice C) may be necessary in cases of dehydration or shock but would not directly address respiratory distress. Providing chest physiotherapy (Choice D) can help mobilize secretions in conditions like cystic fibrosis but is not the first-line intervention for respiratory distress.

5. A nurse is caring for a client who has a prescription for spironolactone. Which of the following laboratory values should the nurse monitor?

• A. Sodium 140 mEq/L
• B. Calcium 9.5 mg/dL
• C. Potassium 5.2 mEq/L
• D. Magnesium 2.0 mEq/L

Correct answer: C

Rationale: The correct answer is C: Potassium 5.2 mEq/L. A potassium level of 5.2 mEq/L is elevated and should be monitored in clients taking spironolactone, which is a potassium-sparing medication. Monitoring potassium levels is crucial as spironolactone can cause hyperkalemia. Choices A, B, and D are incorrect because sodium, calcium, and magnesium levels are not typically affected by spironolactone. Therefore, the nurse should primarily focus on monitoring the potassium levels in this scenario.
