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. After change-of-shift report, which patient should the nurse assess first?

• A. 72-year-old with cor pulmonale who has 4+ bilateral edema in his legs and feet
• B. 28-year-old with a history of a lung transplant and a temperature of 101 F (38.3 C)
• C. 40-year-old with a pleural effusion who is complaining of severe stabbing chest pain
• D. 64-year-old with lung cancer and tracheal deviation after subclavian catheter insertion

Correct answer: D

Rationale: The patient with lung cancer and tracheal deviation after a subclavian catheter insertion should be assessed first. Tracheal deviation can indicate tension pneumothorax, a life-threatening condition that requires immediate intervention to prevent inadequate cardiac output or hypoxemia. While the other patients also need assessment, the potential for tension pneumothorax in the patient with tracheal deviation necessitates urgent attention to prevent complications.

3. The client is a chronic carrier of infection. To prevent the spread of the infection to other clients or healthcare providers, the nurse emphasizes interventions that do which of the following? (Berman & Snyder, 2012, p. 713)

• A. Eliminate the reservoir
• B. Block the portal of exit from the reservoir
• C. Block the portal of entry into the host
• D. Decrease the susceptibility of the host

Correct answer: B

Rationale: To prevent the spread of infection from a chronic carrier, the nurse should focus on blocking the portal of exit from the reservoir, which is the carrier person. By preventing the movement of the organism from the reservoir, the infection can be contained. Eliminating the reservoir is not feasible in this case as the carrier is a chronic carrier. Blocking the portal of entry into the host or decreasing the susceptibility of the host would only impact individual prevention and not the spread from the carrier to others.

4. During a client interview, which of the following leading questions should the nurse avoid asking?

• A. What medication do you take at home?
• B. You are really excited about the plastic surgery, aren't you?
• C. Were you aware I've had this same type of surgery?
• D. What would you like to talk about?

Correct answer: B

Rationale: The nurse should avoid asking leading questions during a client interview as they can influence the client's response. Option B is a leading question as it suggests an expected response from the client, potentially biasing the information provided. This can lead to inaccurate data collection and subsequent errors in diagnostic reasoning. Choices A, C, and D are open-ended questions that encourage the client to provide unbiased information and allow for a more comprehensive assessment.

5. A client is diagnosed with ariboflavinosis. Which of the following foods should the nurse serve this client?

• A. Citrus fruits
• B. Milk
• C. Fish
• D. Potatoes

Correct answer: B

Rationale: Ariboflavinosis is a vitamin B-2 deficiency. Symptoms may include cracks around the mouth, inflammation of the tongue, or light sensitivity. Foods rich in vitamin B-2, like milk, liver, green vegetables, or whole grains, are recommended. Citrus fruits (choice A) are good sources of vitamin C, not B-2. Fish (choice C) is a source of protein and omega-3 fatty acids but not a significant source of vitamin B-2. Potatoes (choice D) are a source of carbohydrates but do not provide high levels of vitamin B-2.
