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. Which of the following actions can help prevent a fire in the area where a healthcare professional works?

• A. Using an adaptor when plugging in client equipment
• B. Marking equipment that is not working properly and using it carefully until it can be inspected by maintenance
• C. Notifying visitors or posting signs that indicate oxygen is in use in certain areas
• D. Keeping extra equipment stored in one area with other supplies and materials

Correct answer: C

Rationale: The correct action to help prevent a fire in a healthcare setting is to notify visitors or post signs indicating that oxygen is in use in certain areas. Oxygen is a combustible material, and awareness of its presence is crucial to prevent fire hazards. By informing all individuals in the facility about the use of oxygen through clear signs or notifications, the risk of improper use and potential fire accidents can be minimized. Choice A is incorrect because using an adaptor when plugging in client equipment is not directly related to fire prevention. Choice B is also incorrect as marking faulty equipment and using it until inspection does not directly address fire prevention. Choice D is not a recommended action for fire prevention; storing extra equipment with supplies does not address the specific fire risk associated with oxygen use.

3. Which nursing intervention is most appropriate to reduce environmental stimuli that may cause discomfort for a client?

• A. Loosen pressure dressings on wounds
• B. Use assistance to lift a client in bed
• C. Check temperature of water used in a sponge bath
• D. Position the client in a prone position

Correct answer: C

Rationale: To reduce environmental stimuli that may cause discomfort for a client, nurses can implement various interventions. Checking the temperature of the water used in a sponge bath is crucial to prevent burns from water that is too hot or discomfort from water that is too cold. This intervention addresses a common source of discomfort for clients during personal care. Loosening pressure dressings on wounds, although important for wound care, does not directly address environmental stimuli. Using assistance to lift a client in bed is about proper positioning and preventing injury rather than reducing environmental stimuli. Positioning the client prone is not a suitable intervention for reducing discomfort caused by environmental stimuli.

4. A registered nurse who usually works in a spinal rehabilitation unit is floated to the emergency department. Which of these clients should the charge nurse assign to this RN?

• A. A middle-aged client who says, "I took too many diet pills"? and "my heart feels like it is racing out of my chest."?
• B. A young adult who says, "I hear songs from heaven. I need money for beer. I quit drinking two (2) days ago for my family. Why are my arms and legs jerking?"?
• C. An adolescent who has been on pain medications for terminal cancer with an initial assessment finding of pinpoint pupils and a relaxed respiratory rate of 11.
• D. An elderly client who reports having taken a "large crack hit"? 10 minutes prior to walking into the emergency room.

Correct answer: C

Rationale: When assigning a floated nurse from another unit to a client in the emergency department, the goal is to choose a patient with minimal anticipated immediate complications. In this scenario, the adolescent with terminal cancer who has been on pain medications and presents with pinpoint pupils and a relaxed respiratory rate of 11 is the most stable option. These assessment findings indicate opioid toxicity, which, while serious, has the least risk of immediate complications compared to the other clients. Choice A involves a middle-aged client experiencing symptoms of possible cardiac issues due to diet pill overdose, which requires urgent intervention. Choice B presents a young adult with concerning symptoms of potential psychosis or substance withdrawal, requiring immediate attention. Choice D involves an elderly client who recently used crack, posing a high-risk situation that requires prompt evaluation and intervention. Therefore, the correct choice is the adolescent with opioid toxicity, as this client has the least immediate risk of complications among the options provided.

5. A 6-month-old infant has been brought to the well-child clinic for a checkup. The infant is currently sleeping. What would the nurse do first when beginning the examination?

• A. Wake the infant before beginning the examination.
• B. Examine the infant's hips before the infant wakes up.
• C. Auscultate the lungs and heart while the infant is still sleeping.
• D. Begin with the assessment of the eye and continue with the remainder of the examination in a head-to-toe approach.

Correct answer: C

Rationale: When the infant is quiet or sleeping, it is an ideal time to assess the cardiac, respiratory, and abdominal systems. It is recommended not to wake the infant unnecessarily. Auscultating the lungs and heart while the infant is still sleeping allows for a comprehensive assessment without disturbing the infant. Examining the infant's hips prematurely may disrupt the infant's sleep. Starting with an assessment of the eye is not appropriate as it is an invasive procedure and should be performed towards the end of the examination after the non-invasive assessments have been completed.
