Nursing Elites

1. Which of the following statements best describes substance P?

• A. Substance P decreases a client's sensitivity to pain
• B. Substance P levels are drawn before administration of narcotic analgesics
• C. Substance P is found in the brain and is responsible for pain control and management of depression
• D. Substance P is found in the dorsal horn of the spinal column

Correct answer: D

Rationale: Substance P is a neurotransmitter found in the brain and the dorsal horn of the spinal column, not just in the brain. It is associated with pain transmission and modulation. Substance P is known to cause inflammation, edema, and pain. While it plays a role in pain perception, it does not decrease a client's sensitivity to pain (Choice A), nor are its levels typically drawn before administering narcotic analgesics (Choice B). Although substance P is involved in pain control, it is not responsible for managing depression (Choice C). Therefore, the correct statement is that substance P is found in the dorsal horn of the spinal column.

2. A nurse is preparing to irrigate a client's indwelling catheter through a closed, intermittent system. Which of the following steps must the nurse take as part of this process?

• A. Use sterile solution at room temperature
• B. Position the client in a comfortable position
• C. Clamp the catheter at the level above the injection port
• D. Inject sterile solution through the injection port into the catheter

Correct answer: D

Rationale: When performing closed intermittent system catheter irrigation, the nurse should use sterile solution at room temperature with sterile technique. It is important to position the client comfortably for easy access to the catheter site and to assess the abdomen during the procedure. Clamping the catheter should be done below the level of the injection port, not above. The correct step is to inject sterile solution through the injection port into the catheter, allowing the fluid to travel up the catheter to irrigate the tubing and the bladder.

3. A healthcare professional is asked to draw blood in the antecubital (AC) space. Which of the following veins are found in the AC?

• A. Cephalic
• B. Median cubital
• C. Basilic
• D. All of the above

Correct answer: D

Rationale: The correct answer is 'All of the above.' All three of these veins - the cephalic, median cubital, and basilic veins - are located in the antecubital space, which is the area in front of the elbow on the arm. The cephalic vein runs along the outer side of the arm, the basilic vein runs along the inner side of the arm, and the median cubital vein is a connecting vein between the cephalic and basilic veins. Therefore, all three veins can be accessed when drawing blood from the antecubital space. Choices A, B, and C are incorrect because each of these veins individually can be found in the antecubital space.

4. What is the initial step to take when a patient passes out at the front desk?

• A. Call 911.
• B. Initiate CPR.
• C. Shake the patient and ask if they are okay.
• D. Check for a pulse.

Correct answer: C

Rationale: The correct initial step when a patient passes out at the front desk is to shake the patient gently and ask if they are okay. This step aims to assess the patient's level of responsiveness. Checking for a pulse or initiating CPR should only be done if the patient does not respond to being shaken. Calling 911 can be the next step after assessing the patient's immediate condition and providing necessary assistance.

5. A healthcare professional is employed at a district health department and must spend several hours each day sitting at a desk. Which principle of ergonomics will most likely help them to reduce the risk of injury or pain in this situation?

• A. Adjust the chair height to keep the legs bent at the hips at a 90-degree angle
• B. Maintain the position of the computer monitor just below eye level
• C. Stand up and take a walk or stretch every 4 hours
• D. Rest wrists on the edge of the desk while typing

Correct answer: A

Rationale: When sitting for prolonged periods, it is important to adjust the height of the chair so that the legs are bent at the hips at a 90-degree angle. This position helps to reduce pressure on the back, legs, and feet, promoting better posture and reducing muscle fatigue. Standing up and moving around at least once every hour is crucial to support circulation and prevent stiffness. Maintaining the position of the computer monitor just below eye level helps reduce strain on the neck and eyes. Resting wrists on the edge of the desk while typing can lead to wrist strain and discomfort, so it is not an ergonomic recommendation for prolonged desk work.
