Nursing Elites

1. A 20-year-old female attending college is found unconscious in her dorm room. She has a fever and a noticeable rash. She has just been admitted to the hospital. Which of the following tests is most likely to be performed first?

• A. Blood sugar check
• B. CT scan
• C. Blood cultures
• D. Arterial blood gases

Correct answer: C

Rationale: The most likely test to be performed first in this scenario is blood cultures. Blood cultures are crucial to investigate the fever and rash symptoms in an unconscious patient. This test is used to detect foreign invaders like bacteria, yeast, and other microorganisms in the blood, which could indicate a blood infection (bacteremia). A positive blood culture result confirms the presence of bacteria in the blood. A blood sugar check (choice A) may be important but is less likely to be the first test in this context. A CT scan (choice B) and arterial blood gases (choice D) are generally not the initial tests performed to investigate a fever and rash with altered mental status.

2. A patient asks a nurse administering blood how long red blood cells live in the body. What is the correct response?

• A. The life span of RBC is 45 days
• B. The life span of RBC is 60 days
• C. The life span of RBC is 90 days
• D. The life span of RBC is 120 days

Correct answer: D

Rationale: The correct answer is that red blood cells have a lifespan of 120 days in the body. This allows for efficient oxygen transport throughout the circulatory system. Choices A, B, and C are incorrect because the lifespan of red blood cells is actually 120 days. Understanding the lifespan of red blood cells is crucial in assessing various conditions related to blood cell production and turnover.

3. A 3-year-old had a hip spica cast applied 2 hours ago. In order to facilitate drying, the nurse should:

• A. Expose the cast to air and turn the child frequently.
• B. Use a heat lamp to reduce the drying time.
• C. Handle the cast with the abductor bar.
• D. Turn the child as little as possible.

Correct answer: A

Rationale: After a hip spica cast is applied, it is important to facilitate drying by exposing the cast to air and turning the child frequently, approximately every 2 hours. This helps ensure even drying and prevents skin breakdown. Using a heat lamp can cause burns and should be avoided. Handling the cast with the abductor bar is not necessary for the drying process and may cause discomfort to the child. Turning the child as little as possible is not recommended as regular turning helps prevent complications like pressure ulcers and stiffness.

4. The nurse is counting a client's respiratory rate. During a 30-second interval, the nurse counts six respirations, and the client coughs three times. In repeating the count for a second 30-second interval, the nurse counts eight respirations. Which respiratory rate should the nurse document?

• A. 14
• B. 16
• C. 17
• D. 28

Correct answer: B

Rationale: The most accurate respiratory rate is the second count obtained by the nurse, which was not interrupted by coughing. The nurse counted eight respirations over 30 seconds, so doubling this count gives a respiratory rate of 16 breaths per minute. This calculation is based on the assumption that the client's breathing pattern remained relatively stable during the two 30-second intervals. Options A, C, and D are incorrect because they do not reflect the accurate count obtained without interruptions. Choice B (16) is the correct answer as it reflects the uninterrupted count of respirations by the nurse.

5. A patient is undergoing a stress test on a treadmill and turns to talk to the nurse. Which of these statements would require the most immediate intervention?

• A. I'm feeling extremely thirsty and will get some water after this.
• B. I can feel my heart racing.
• C. My shoulder and arm are hurting.
• D. My blood pressure reading is 158/80

Correct answer: C

Rationale: The correct answer is 'C: My shoulder and arm are hurting.' Unilateral arm and shoulder pain are classic symptoms of myocardial ischemia, indicating possible heart issues. In this scenario, immediate intervention is required, and the stress test should be halted. Choice A about feeling thirsty does not indicate an acute medical issue. Choice B mentioning heart racing is expected during a stress test. Choice D, a blood pressure reading of 158/80, while slightly elevated, does not present an immediate concern compared to the symptoms of arm and shoulder pain suggesting cardiac distress.
