Nursing Elites

1. When considering the concepts related to blood pressure, which statement best describes the concept of mean arterial pressure (MAP)?

• A. MAP is the pressure of the arterial pulse.
• B. MAP reflects the stroke volume of the heart.
• C. MAP is the pressure forcing blood into the tissues, averaged over the cardiac cycle.
• D. MAP is an average of the systolic and diastolic blood pressures and reflects tissue perfusion.

Correct answer: C

Rationale: Mean Arterial Pressure (MAP) is the pressure that forces blood into the tissues, averaged over the cardiac cycle. It is not the pressure of the arterial pulse (Choice A), nor does it directly reflect the stroke volume of the heart (Choice B). While MAP involves systolic and diastolic pressures, it is not simply an average of these two values as diastole lasts longer. Instead, MAP is closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it represents the pressure forcing blood into the tissues, averaged over the cardiac cycle.

2. A student is late for an appointment and has rushed across campus to the health clinic. How should the nurse proceed?

• A. Allow 5 minutes for the student to relax and rest before checking their vital signs.
• B. Check the blood pressure in both arms, expecting a difference in the readings due to the recent exercise.
• C. Immediately monitor the student's vital signs upon arrival at the clinic and then 5 minutes later, recording any differences.
• D. Check the student's blood pressure in the supine position to provide a more accurate reading and allow the student to relax at the same time.

Correct answer: A

Rationale: To ensure an accurate blood pressure reading, it is important for the student to be in a relaxed state. Allowing at least a 5-minute rest period helps reduce anxiety and provides a valid blood pressure measurement. Checking the blood pressure in both arms is unnecessary unless there is a specific reason to suspect an issue, and recent exercise should not significantly impact the readings. Monitoring vital signs immediately upon arrival may not yield accurate results due to the rush and anxiety of the student. Checking blood pressure in the supine position is not necessary in this scenario and does not provide a more accurate reading.

3. 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.

4. To collect timely, specific information, the nurse is most likely to ask which of the following questions?

• A. Would you describe what you are feeling?
• B. How are you today?
• C. What would you like to talk about?
• D. Where does it hurt?

Correct answer: A

Rationale: The correct answer is, 'Would you describe what you are feeling?' This open-ended question prompts the patient to provide subjective data, offering specific information about their current health status and human responses. This information can help identify actual or potential health issues. Choices B and C are more likely to yield general, nonspecific information. Choice D may lead to a brief response or nonverbal indication of pain location. A more effective approach to gather specific information about pain would be to ask, 'Can you describe any pain you are experiencing?'

5. According to the American Heart Association standards, high-quality CPR for an adult includes all of the following EXCEPT:

• A. Push hard
• B. Push fast
• C. Allow chest recoil between compressions
• D. Pause CPR as each drug is administered

Correct answer: D

Rationale: High-quality CPR for adults should not be paused for drug administration. The correct CPR technique involves pushing hard and fast, at a rate of at least 100 compressions per minute and to a depth of at least 2 inches. It is also essential to allow chest recoil between compressions to enable proper blood circulation. Pausing CPR for drug administration would delay the delivery of continuous chest compressions, which are crucial for maintaining blood flow and oxygenation during cardiac arrest.
