Nursing Elites

1. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

• A. External light sources may cause falsely high oximetry values
• B. A bright light in the client's face may cause a low pulse oximetry
• C. External light sources may cause falsely low oximetry values
• D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.

2. What kind of preventive measures is MOST likely to be used to prevent Mary Eden from falling due to her muscular frailty?

• A. Physical therapy for muscle strengthening exercises
• B. Physical therapy for range of motion exercises
• C. Occupational therapy to help her with confusion
• D. Medications to help her sleep more

Correct answer: A

Rationale: Mary Eden, due to her muscular frailty, is at risk of falling. The most effective preventive measure in this case would be physical therapy focusing on muscle strengthening exercises. Strengthening exercises can help improve her muscle tone and stability, reducing the risk of falls. While range of motion exercises may be beneficial, they may not directly address her muscular frailty and stability concerns as effectively as muscle strengthening exercises. Occupational therapy aims to help individuals with activities of daily living and functional tasks, not confusion. Medications to induce more sleep can actually increase the risk of falls due to potential side effects like dizziness or disorientation, rather than preventing falls.

3. Your patient has been diagnosed with a left ankle sprain. On the discharge instructions, the physician has prescribed the RICE protocol. This acronym stands for:

• A. Rest, Ice, Compression, Elevation
• B. Radiology, Ice, Compression, Elevation
• C. Rest, Ice, Cast, Elevation
• D. Radiology, Ice, Cast, Elevation

Correct answer: A

Rationale: The correct answer is Rest, Ice, Compression, Elevation. This acronym, RICE, is commonly used for the treatment of injuries like an ankle sprain. Rest allows the injured area to heal, Ice helps reduce swelling and pain (20 minutes on each hour while awake), Compression is usually achieved with an elastic bandage to minimize swelling, and Elevation of the foot above the level of the heart assists in reducing swelling and promoting healing. Choices B, C, and D are incorrect because they include irrelevant terms like Radiology and Cast, which are not part of the standard treatment protocol for an ankle sprain.

4. A client is refusing to undergo any more treatments in the hospital and wants to leave against medical advice. When the nurse requests the client to sign an AMA order, the client refuses and leaves. What is the next action of the nurse?

• A. Call security to hold the client until he signs the order
• B. Notify the physician to convince the client to stay
• C. Speak with the client's spouse to persuade him to stay
• D. Allow the client to leave and document the refusal in his chart

Correct answer: D

Rationale: The nurse cannot force the client to stay in the hospital to receive treatment or to sign an AMA order. It is essential to respect the client's autonomy and decision-making capacity. While involving security or pressuring the client through the physician or spouse may seem like options, they are not appropriate in this situation. The nurse should allow the client to leave if they are competent to make that decision, document the refusal in the client's chart to ensure all actions are appropriately documented, and follow institutional policies for patients leaving against medical advice.

5. A patient in the cardiac unit is concerned about the risk factors associated with atherosclerosis. Which of the following are hereditary risk factors for developing atherosclerosis?

• A. Family history of heart disease
• B. Overweight
• C. Smoking
• D. Age

Correct answer: A

Rationale: A family history of heart disease is an inherited risk factor for developing atherosclerosis. This factor is not modifiable through lifestyle changes. Studies have shown that having a first-degree relative with heart disease significantly increases the individual's risk of developing atherosclerosis. Overweight, smoking, and age are not hereditary risk factors for atherosclerosis. Overweight and smoking are lifestyle-related risk factors, while age is a non-modifiable risk factor that increases with time but is not directly inherited.
