Nursing Elites

1. Which of the following actions is most appropriate for reducing the risk of infection during the post-operative period?

• A. Flush the central line with heparin at least every four hours
• B. Administer narcotic analgesics as needed
• C. Remove the urinary catheter as soon as the client is ambulatory
• D. Order a high-protein diet for the client

Correct answer: C

Rationale: The most appropriate action to reduce the risk of infection during the post-operative period is to remove the urinary catheter as soon as the client is ambulatory. Urinary catheters can serve as a source of bacteria, increasing the risk of infection in the bladder or urethra. By removing the catheter promptly once the client is mobile, the risk of infection can be minimized. Option A, flushing the central line with heparin, is not directly related to reducing urinary tract infections. Option B, administering narcotic analgesics as needed, is important for pain management but does not directly address infection prevention. Option D, ordering a high-protein diet, may be beneficial for wound healing but does not specifically target infection risk reduction in the post-operative period.

2. The nurse is planning care for a patient with a wrist restraint. How often should a restraint be removed, the area massaged, and the joints moved through their full range?

• A. Once a shift
• B. Once an hour
• C. Every 2 hours
• D. Every 4 hours

Correct answer: C

Rationale: Restraints should be removed every 2 hours to prevent complications. Moving the joints through their full range of motion helps prevent muscle shortening and contractures. Massaging the area promotes circulation and reduces the risk of pressure injuries. Removing restraints less frequently could lead to complications like decreased circulation and skin breakdown. Options A, B, and D are incorrect because they do not align with the standard practice of removing restraints every 2 hours to ensure patient safety and well-being.

3. The body system that functions to maintain fluid balance, support immunity, and contains the spleen is the:

• A. Lymphatic System
• B. Digestive System
• C. Urinary System
• D. Respiratory System

Correct answer: A

Rationale: The Lymphatic System is responsible for maintaining fluid balance and supporting immunity. It contains organs like the spleen, tonsils, thymus, lymph nodes, and lymph vessels. The spleen, a part of the lymphatic system, plays a crucial role in filtering blood and storing blood cells. The Digestive System is primarily involved in the breakdown and absorption of nutrients, not fluid balance or immunity. The Urinary System is responsible for filtering waste products from the blood and regulating fluid balance, but it does not support immunity or contain the spleen. The Respiratory System is focused on gas exchange and oxygenating the blood, not fluid balance or immunity.

4. The Sinoatrial Node (SA) is located within which of the following heart structures?

• A. Mitral Valve
• B. Right Ventricle
• C. Right Atrium
• D. Left Atrium

Correct answer: C

Rationale: The Sinoatrial (SA) Node, often called the heart's natural pacemaker, is situated within the upper wall of the Right Atrium. It initiates the electrical impulses that regulate the heartbeat. Choices A, B, and D are incorrect because the SA node is not located in the Mitral Valve, Right Ventricle, or Left Atrium. It is specifically positioned in the Right Atrium to coordinate the heart's rhythm and timing.

5. When checking for proper blood pressure cuff size, which guideline is correct?

• A. The standard cuff size is appropriate for all sizes.
• B. The length of the rubber bladder should equal 80% of the arm circumference.
• C. The width of the rubber bladder should equal 80% of the arm circumference.
• D. The width of the rubber bladder should equal 40% of the arm circumference.

Correct answer: D

Rationale: When selecting the correct blood pressure cuff size, it is essential to ensure that the width of the rubber bladder equals 40% of the circumference of the person's arm. This ensures proper fitting and accurate readings. The length of the bladder should actually equal 80% of the arm circumference, not 80% of the width, making choices B and C incorrect. Choice A stating that the standard cuff size is appropriate for all sizes is inaccurate, as using an incorrectly sized cuff can lead to inaccurate blood pressure readings.
