Nursing Elites

1. What can cause a low pulse oximetry reading?

• A. Hyperthermia
• B. Increased hemoglobin level
• C. Inadequate peripheral circulation
• D. Low altitudes

Correct answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.

2. When teaching a client about the correct use of a cane, what should the nurse include?

• A. Ensure the cane has a rubber cap
• B. Hold the cane on the stronger side
• C. Flex the elbow slightly when using the cane
• D. Use a quad cane for increased support

Correct answer: B

Rationale: When using a cane, it should be held on the stronger side to provide optimal support and stability. This positioning allows the cane to bear weight effectively and helps in improving balance. Option A about ensuring the cane has a rubber cap is important for preventing slipping but is not directly related to the correct use of the cane. Option C, flexing the elbow slightly, is a general guideline and may vary depending on the individual's height and the type of cane being used. Option D suggesting the use of a quad cane for increased support is not necessary if a standard cane is sufficient for the client's needs.

3. A nurse is planning care for a client who has a chest tube. Which of the following actions should the nurse take to ensure proper functioning of the chest tube?

• A. Clamp the chest tube intermittently.
• B. Keep the drainage system below chest level.
• C. Empty the drainage chamber every 4 hours.
• D. Apply sterile gauze around the insertion site daily.

Correct answer: B

Rationale: To ensure proper functioning of a chest tube, the nurse should keep the drainage system below chest level. This position allows for proper drainage by gravity and prevents backflow into the pleural space. Clamping the chest tube intermittently can lead to a buildup of pressure and should be avoided. Emptying the drainage chamber every 4 hours is important but not directly related to maintaining the chest tube's function. Applying sterile gauze around the insertion site daily is essential for infection prevention but does not specifically ensure the proper functioning of the chest tube.

4. A nurse is caring for a client with encephalopathy secondary to liver failure. The client has been prescribed a high-calorie, low-protein diet. Which of the following meal selections is appropriate for this client?

• A. Scrambled eggs, bacon, and pancakes
• B. Grilled cheese sandwich, potato chips, chocolate pudding
• C. Steak, French fries, corn
• D. Chicken breast, mashed potatoes, spinach

Correct answer: D

Rationale: The correct answer is D: Chicken breast provides a low-fat protein source, and mashed potatoes and spinach provide high-calorie nutrients suitable for managing liver failure. Option A (Scrambled eggs, bacon, and pancakes) is high in protein, which is not suitable for a low-protein diet. Option B (Grilled cheese sandwich, potato chips, chocolate pudding) contains high protein and may not be appropriate for the client. Option C (Steak, French fries, corn) is high in protein and fat, which are not recommended for this client's dietary requirements.

5. A healthcare provider is assessing a client who has a heart rate of 40/min. The client is diaphoretic and has chest pain. Which of the following medications should the healthcare provider plan to administer?

• A. Lidocaine
• B. Adenosine
• C. Atropine
• D. Verapamil

Correct answer: C

Rationale: The client presents with bradycardia, diaphoresis, and chest pain, indicating reduced cardiac output. Atropine is the appropriate choice as it increases heart rate by blocking the parasympathetic nervous system. Lidocaine is used for ventricular arrhythmias, Adenosine for supraventricular tachycardia, and Verapamil for controlling heart rate in atrial fibrillation or atrial flutter. These medications are not suitable for the client's current presentation.
