Nursing Elites

1. One of your patients is dependent on a mechanical ventilator for their respiratory needs. The patient cannot breathe on their own. Suddenly, the lights in the patient's room and the entire nursing unit go off. You realize that the electric power has been lost. What is the first thing that you should do for this patient?

• A. Plug the ventilator into the red outlet in the room.
• B. Plug the ventilator into the blue outlet in the room.
• C. Use an Ambu bag to ventilate the patient.
• D. Call the doctor about this emergency.

Correct answer: B

Rationale: In healthcare facilities, emergency generators are in place in case of power outages. The red outlets in patient rooms are connected to the emergency generator and provide power during such situations. By plugging the ventilator into the red outlet, you ensure that the patient's mechanical ventilation needs are met despite the power loss. Using an Ambu bag or calling the doctor should be secondary actions after ensuring the ventilator is powered correctly. Plugging the ventilator into the blue outlet is incorrect and can result in the ventilator not functioning during a power outage.

2. What is a common error when taking a pulse?

• A. Placing the index finger on the radial artery located on the thumb side of a patient's wrist.
• B. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure.
• C. Counting the pulse for 15 seconds and multiplying the number by four.
• D. None of the above will cause errors.

Correct answer: C

Rationale: The correct answer is counting the pulse for 15 seconds and multiplying the number by four. To accurately assess a patient's heart rate or pulse, it is crucial to count the pulse for a full minute. Counting for only 15 seconds and then multiplying by four may result in an inaccurate heart rate calculation. This approach could miss arrhythmias or intermittent pulsations that could be vital indicators of the patient's condition. Placing the index finger on the radial artery, which is located on the thumb side of the patient's wrist, is the correct technique for taking a pulse. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure is a valid observation and not an error in itself. Therefore, the most common error in this scenario is incorrectly calculating the pulse rate by multiplying a 15-second count by four.

3. During an assessment, a nurse asks a patient, "If you had fever and vomiting for 3 days, what would you do?"? Which aspect of the mental status examination is the nurse assessing?

• A. Behavior
• B. Cognition
• C. Affect and mood
• D. Perceptual disturbances

Correct answer: B

Rationale: The nurse is assessing cognition in this scenario. Cognition involves evaluating a patient's judgment and decision-making abilities. By asking the patient what they would do in a specific situation, the nurse aims to determine the patient's cognitive function. A correct response indicating intact cognition would involve a decision like 'Call my doctor.' If the patient suggests inappropriate actions like 'I would stop eating' or 'I would just wait and see what happened,' it would suggest impaired judgment. The other options, behavior, affect and mood, and perceptual disturbances, refer to different aspects of the mental status examination and are not directly assessed through this question.

4. Your patient ate an 8-ounce cup of Italian ice. How much will you record on the patient's Intake and Output form in terms of this patient's fluid intake?

• A. 240 cc
• B. 120 cc
• C. 8 cc
• D. 0 cc because Italian ice is not a fluid

Correct answer: A

Rationale: The correct answer is 240 cc. Italian ice is considered a fluid, so you would record the intake of 240 cc. Choice B (120 cc) and Choice C (8 cc) are incorrect as they do not reflect the correct amount of fluid intake from an 8-ounce cup of Italian ice. Choice D (0 cc) is incorrect because Italian ice does count as a fluid intake and should be recorded as such.

5. An examiner is using an ophthalmoscope to examine a patient's eyes. The patient has astigmatism and is nearsighted. Which of these techniques by the examiner would indicate that the examination is being correctly performed?

• A. Rotating the lens selector dial to bring the object into focus
• B. Using the large full circle of light when assessing pupils that are not dilated
• C. Rotating the lens selector dial to the black numbers to compensate for astigmatism
• D. Using the grid on the lens aperture dial to visualize the external structures of the eye

Correct answer: A

Rationale: To correctly perform an eye examination using an ophthalmoscope on a patient with astigmatism and nearsightedness, the examiner should rotate the lens selector dial to bring the object into focus. This adjustment helps compensate for nearsightedness or farsightedness but does not correct astigmatism. Rotating the lens selector dial to the black numbers is not an appropriate technique for compensating for astigmatism. Using the grid on the lens aperture dial is primarily for visualizing external structures of the eye, not for addressing refractive errors. The large full circle of light is typically used when assessing dilated pupils, not for examining patients with astigmatism and nearsightedness. Therefore, the correct technique is rotating the lens selector dial to bring the object into focus.
