Nursing Elites

1. A nurse is reviewing the laboratory results of a client who has hypokalemia. Which of the following findings should the nurse expect?

• A. Serum potassium 5.4 mEq/L
• B. Flat T waves
• C. Elevated ST segments
• D. Bradycardia

Correct answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

2. A healthcare provider is reviewing the medical record of a client who has schizophrenia and is taking clozapine. Which finding should the healthcare provider identify as a contraindication to the administration of clozapine?

• A. Heart rate 58/min.
• B. Fasting blood glucose 100 mg/dL.
• C. Hgb 14 g/dL.
• D. WBC count 2,900/mm3.

Correct answer: D

Rationale: The correct answer is D: a low WBC count. Clozapine can suppress bone marrow function, leading to a decreased white blood cell count. This condition, known as agranulocytosis, increases the risk of severe infections. Monitoring WBC counts is essential during clozapine therapy. Choices A, B, and C are within normal ranges and are not contraindications for administering clozapine.

3. A nurse is preparing to administer medications to a client who has a nasogastric (NG) tube. Which of the following actions should the nurse take first?

• A. Check for tube placement.
• B. Flush the NG tube with 0.9% sodium chloride.
• C. Administer the medications as a bolus.
• D. Dissolve the medications in 30 mL of sterile water.

Correct answer: A

Rationale: The correct first action for the nurse to take when preparing to administer medications to a client with a nasogastric (NG) tube is to check for tube placement. This step is crucial to ensure that the NG tube is correctly positioned in the stomach and not in the respiratory tract, reducing the risk of aspiration. Flushing the NG tube with 0.9% sodium chloride, administering the medications as a bolus, or dissolving the medications in sterile water should only be done after confirming the proper placement of the NG tube. Therefore, options B, C, and D are incorrect as they precede the essential step of verifying tube placement.

4. A nurse in an emergency department is assessing a client who reports ingesting thirty diazepam tablets. After securing the client's airway and initiating an IV, which of the following actions should the nurse take next?

• A. Monitor the client's IV site for thrombophlebitis
• B. Administer flumazenil to the client
• C. Evaluate the client for further suicidal behavior
• D. Initiate seizure precautions for the client

Correct answer: B

Rationale: In cases of benzodiazepine overdose, such as diazepam ingestion, flumazenil is the antidote. Therefore, the priority action for the nurse is to administer flumazenil to the client. Monitoring the IV site for thrombophlebitis (Choice A) is important but not the immediate priority. Evaluating the client for further suicidal behavior (Choice C) is important but not the next immediate action. Initiating seizure precautions (Choice D) is not the priority as the client's airway has already been secured.

5. What is the priority nursing intervention for a patient experiencing an acute asthma attack?

• A. Administer bronchodilators
• B. Monitor oxygen saturation
• C. Provide supplemental oxygen
• D. Start IV fluids

Correct answer: A

Rationale: The correct answer is to administer bronchodilators. In an acute asthma attack, the priority is to open the airways and improve airflow. Bronchodilators like albuterol are crucial in providing immediate relief to the patient. Monitoring oxygen saturation (choice B) is important but administering bronchodilators takes precedence in managing the acute attack. Providing supplemental oxygen (choice C) may be necessary but addressing the airway obstruction with bronchodilators is the priority. Starting IV fluids (choice D) is not the priority in an acute asthma attack unless specifically indicated for other reasons such as dehydration.
