Nursing Elites

1. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?

• A. Narrowed QRS complex
• B. Shortened "PR"? interval
• C. Tall peaked "T"? waves
• D. Prominent "U"? waves

Correct answer: C

Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.

2. A client with myocardial infarction is receiving tissue plasminogen activator, alteplase (Activase, tPA). While on the therapy, the nurse plans to prioritize which of the following?

• A. Observe for neurological changes
• B. Monitor for any signs of renal failure
• C. Check the food diary
• D. Observe for signs of bleeding

Correct answer: D

Rationale: The priority concern for a client receiving thrombolytic medication, such as tissue plasminogen activator (alteplase), is to monitor for signs of bleeding. Thrombolytics work by converting plasminogen to plasmin, which degrades fibrin. This process can lead to the breakdown of both fibrin-bound plasminogen on thrombi surfaces and unbound plasminogen in the plasma. The resulting plasmin can degrade fibrin, fibrinogen, factor V, and factor VIII. Observing for signs of bleeding is crucial due to the increased risk of hemorrhage associated with thrombolytic therapy. Monitoring for neurological changes, signs of renal failure, or checking the food diary are not the immediate priorities compared to detecting and managing potential bleeding complications.

3. A patient with bacterial pneumonia has rhonchi and thick sputum. What is the nurse's most appropriate action to promote airway clearance?

• A. Assist the patient to splint the chest when coughing.
• B. Teach the patient about the need for fluid intake.
• C. Encourage the patient to wear the nasal oxygen cannula.
• D. Instruct the patient on the pursed lip breathing technique.

Correct answer: A

Rationale: Assisting the patient to splint the chest when coughing is the most appropriate action to promote airway clearance in a patient with bacterial pneumonia, rhonchi, and thick sputum. Splinting the chest helps reduce pain during coughing and increases the effectiveness of clearing secretions. Teaching the patient about the need for fluid intake is important as it helps liquefy secretions, aiding in easier clearance. Encouraging the patient to wear a nasal oxygen cannula may improve gas exchange but does not directly promote airway clearance. Instructing the patient on the pursed lip breathing technique is beneficial for improving gas exchange in patients with COPD but does not directly aid in airway clearance in a patient with bacterial pneumonia and thick sputum.

4. A client using an intraaural hearing aid experiences whistling after placement. What is the nurse's next action?

• A. Try to reposition the hearing aid
• B. Change the batteries
• C. Remove the device and have it cleaned
• D. Notify the physician that the hearing aid is not working

Correct answer: A

Rationale: An intraaural hearing aid, also known as an in-the-ear hearing aid, is placed in the ear canal. Whistling after placement indicates improper positioning of the device. The correct action for the nurse is to try repositioning the hearing aid to eliminate the whistling. Changing the batteries is not necessary for addressing whistling. Removing the device to clean it is not the immediate action needed for whistling. Notifying the physician is premature without attempting to reposition the hearing aid first.

5. You are responsible for reviewing the nursing unit's refrigerator. Which of the following drugs, if found inside the fridge, should be removed?

• A. Nadolol (Corgard)
• B. Opened (in-use) Humulin N injection
• C. Urokinase (Kinlytic)
• D. Epoetin alfa IV (Epogen)

Correct answer: A

Rationale: Nadolol (Corgard) should be removed if found inside the fridge because it is supposed to be stored at room temperature between 59 to 86 �F (15 and 30 �C) away from heat, moisture, and light. Storing it in the refrigerator can alter its effectiveness and stability. Option B, the opened Humulin N injection, should not be stored in the refrigerator as it is an in-use product and can remain at room temperature for a certain period as per manufacturer guidelines. Option C, Urokinase (Kinlytic), and Option D, Epoetin alfa IV (Epogen), do not require refrigeration and can be stored at room temperature. Therefore, Nadolol (Corgard) is the drug that should be removed from the fridge.
