Nursing Elites

1. A patient diagnosed with hypokalemia is at risk for which condition?

• A. Cardiac dysrhythmias
• B. Muscle weakness
• C. Seizures
• D. Bradycardia

Correct answer: A

Rationale: Patients diagnosed with hypokalemia are at risk for cardiac dysrhythmias due to low potassium levels. Hypokalemia can lead to abnormalities in the electrical conduction system of the heart, potentially causing irregular heart rhythms. Muscle weakness (Choice B) is a symptom commonly associated with hypokalemia, but the question asks about conditions the patient is at risk for, not specific symptoms. Seizures (Choice C) are not typically associated with hypokalemia; they are more commonly linked with conditions such as epilepsy. Bradycardia (Choice D) refers to a slow heart rate, which is not a typical risk associated with hypokalemia; instead, tachycardia (fast heart rate) is more commonly observed in patients with low potassium levels.

2. What is the appropriate electrical intervention for a patient with ventricular tachycardia and a pulse?

• A. Defibrillation
• B. Synchronized cardioversion
• C. Pacing
• D. Medication administration

Correct answer: B

Rationale: Synchronized cardioversion is the correct electrical intervention for a patient with ventricular tachycardia and a pulse. This procedure delivers a synchronized electrical shock to the heart during a specific phase of the cardiac cycle, aiming to restore the heart's normal rhythm. Defibrillation (choice A) is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing (choice C) is typically used for bradycardias or certain types of heart blocks. Medication administration (choice D) may be used in some cases, but in the scenario of ventricular tachycardia with a pulse, synchronized cardioversion is the preferred intervention.

3. A nurse is planning care for a group of postoperative clients. Which of the following interventions should the nurse identify as the priority?

• A. Administer IV pain medication to a client who reports pain as a 6 on a scale of 0 to 10
• B. Administer oxygen to a client who has an oxygen saturation of 91%
• C. Instruct a client who is 1 hr postoperative about coughing and deep breathing exercises
• D. Initiate an infusion of 0.9% sodium chloride for a client who has just had abdominal surgery

Correct answer: B

Rationale: The priority intervention is administering oxygen. Postoperatively, the client's oxygen saturation should be at or above 95%. Oxygen is essential for tissue perfusion and cellular oxygenation. While managing pain is important, oxygenation takes precedence. Instructing a client about coughing and deep breathing exercises is important for preventing respiratory complications but is not as urgent as addressing low oxygen saturation. Initiating an infusion of 0.9% sodium chloride is a routine postoperative intervention for fluid balance but is not the priority when oxygen saturation is low.

4. What intervention is required when continuous bubbling is seen in the chest tube water seal chamber?

• A. Tighten the connections of the chest tube system
• B. Clamp the chest tube
• C. Replace the chest tube
• D. Continue monitoring the chest tube

Correct answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, tightening the connections of the chest tube system is the appropriate intervention. This action can often resolve an air leak, which is the common cause of continuous bubbling. Clamping the chest tube or replacing it is not recommended as the first-line intervention because it may lead to complications or unnecessary tube changes. Continuing to monitor the chest tube without addressing the air leak would delay necessary corrective action, potentially causing respiratory compromise in the patient. Therefore, tightening the connections of the chest tube system is the most suitable initial step to manage continuous bubbling in the water seal chamber.

5. What is the initial nursing action for a patient with chest pain and acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Check the patient's urine output
• C. Check cardiac enzymes
• D. Obtain IV access

Correct answer: A

Rationale: Administering sublingual nitroglycerin is the priority initial action for a patient with chest pain and acute coronary syndrome. Nitroglycerin helps vasodilate coronary arteries, improving blood flow to the heart muscle and reducing chest pain. Checking the patient's urine output (choice B) and cardiac enzymes (choice C) are important assessments but are not the first priority when managing acute chest pain. Obtaining IV access (choice D) is essential for administering medications and fluids, but administering sublingual nitroglycerin takes precedence in the initial management of chest pain in acute coronary syndrome.
