Nursing Elites

1. Which of the following interventions is most appropriate for a patient with left-sided heart failure?

• A. Administering IV fluids.
• B. Administering oxygen.
• C. Administering diuretics.
• D. Administering antihypertensives.

Correct answer: B

Rationale: Administering oxygen is the most appropriate intervention for a patient with left-sided heart failure because it helps improve oxygenation. In left-sided heart failure, the heart struggles to pump oxygen-rich blood to the body, leading to inadequate oxygen supply to tissues. Administering oxygen can help alleviate symptoms of hypoxia and reduce the workload on the heart. IV fluids (Choice A) may exacerbate heart failure by increasing fluid volume, diuretics (Choice C) are used to reduce fluid overload in heart failure, and antihypertensives (Choice D) are more suitable for managing hypertension, which may be a comorbidity in heart failure but are not the primary intervention for left-sided heart failure.

2. An obese client with emphysema who smoked at least a pack of cigarettes daily is admitted after experiencing a sudden increase in dyspnea and activity intolerance. Oxygen therapy is initiated, and it is determined that the client will be discharged with oxygen. Which information is most important for the nurse to emphasize in the discharge teaching plan?

• A. Methods for weight loss
• B. Guidelines for oxygen use
• C. Approaches to conserve energy
• D. Strategies for smoking cessation

Correct answer: B

Rationale: In this scenario, the priority for the nurse to emphasize in the discharge teaching plan is the 'Guidelines for oxygen use.' As the client with emphysema is being discharged with oxygen therapy, it is crucial for the nurse to ensure that the client understands how to use oxygen properly to prevent complications and promote effective management of the condition. While weight loss, conserving energy, and smoking cessation are important aspects of care for this client, in this specific case, ensuring the safe and appropriate use of supplemental oxygen takes precedence to optimize the client's respiratory function and overall well-being.

3. A healthcare professional reviews the blood gas results of a client in respiratory distress. The pH is 7.32, and the PCO2 is 50 mm Hg. Which of the following acid-base imbalances does the professional recognize in these findings?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, the pH is low (<7.35) and the PCO2 is increased (>45 mm Hg). These findings indicate that the client is experiencing respiratory acidosis, a condition where there is an excess of carbon dioxide in the blood due to inadequate ventilation, commonly seen in respiratory distress. Metabolic acidosis (Choice A) is characterized by a low pH and decreased bicarbonate levels, which is not the case in this scenario. Metabolic alkalosis (Choice B) is associated with a high pH and increased bicarbonate levels. Respiratory alkalosis (Choice D) is marked by a high pH and decreased PCO2, opposite to the values presented in the blood gas results of this client.

4. The nurse is caring for a patient who is receiving isotonic intravenous (IV) fluids at an infusion rate of 125 mL/hour. The nurse performs an assessment and notes a heart rate of 102 beats per minute, a blood pressure of 160/85 mm Hg, and crackles auscultated in both lungs. Which action will the nurse take?

• A. Decrease the IV fluid rate and notify the provider.
• B. Increase the IV fluid rate and notify the provider.
• C. Request an order for a colloidal IV solution.
• D. Request an order for a hypertonic IV solution.

Correct answer: A

Rationale: The patient is showing signs of fluid volume excess, indicated by crackles in both lungs, increased heart rate, and elevated blood pressure. To address this, the nurse should decrease the IV fluid rate and notify the provider. Increasing the IV fluid rate would worsen fluid overload. Requesting colloidal or hypertonic IV solutions would exacerbate the issue by pulling more fluids into the intravascular space, leading to further volume overload.

5. The nurse is preparing to administer intravenous gentamicin to an infant through an intermittent needle. The nurse notes that the infant has not had a wet diaper for several hours. The nurse will perform which action?

• A. Administer the medication and give the infant extra oral fluids.
• B. Contact the provider to request adding intravenous fluids when giving the medication.
• C. Give the medication and obtain a serum peak drug level 45 minutes after the dose.
• D. Hold the dose and contact the provider to request a serum trough drug level.

Correct answer: D

Rationale: In this scenario, the infant not having a wet diaper for several hours indicates a potential decrease in urine output, which can be a sign of nephrotoxicity related to gentamicin. The correct action for the nurse is to hold the dose and contact the provider to request a serum trough drug level. This is important to monitor the drug levels and ensure that they are not reaching toxic levels. Administering the medication without addressing the decreased urine output could potentially lead to further nephrotoxicity. Contacting the provider to add intravenous fluids or obtaining a serum peak drug level are not the most appropriate actions in this situation as the priority is to assess for potential nephrotoxicity and ensure patient safety.
