Nursing Elites

1. If Ms. Barrett's distance vision is 20/30, which of the following statements is true?

• A. The client can read from 20' what a person with normal vision can read at 30'.
• B. The client can read from 30' what a person with normal vision can read at 20'.
• C. The client can read the entire chart from 30'.
• D. The client can read the chart from 20' with the left eye and from 30' with the right eye.

Correct answer: A

Rationale: When Ms. Barrett's distance vision is measured as 20/30, it means that she can read from 20 feet away what a person with normal vision can read at 30 feet. The numerator (20) represents the distance in feet between the chart and the client, while the denominator (30) indicates the distance at which a normal eye can read the chart. In this case, Ms. Barrett's vision is slightly worse than normal, as she needs to be closer to the chart to read it clearly. Therefore, choice A is correct. Choices B, C, and D are incorrect: Choice B reverses the distances, Choice C assumes the client can read the entire chart from 30 feet, and Choice D introduces information not related to the 20/30 measurement.

2. An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?

• A. The client has a low cardiac output.
• B. The client has a high cardiac output.
• C. The client has a normal cardiac output.
• D. The client will need a blood transfusion.

Correct answer: C

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.

3. A nurse is explaining a nonstress test to a pregnant client. The nurse explains that the results are nonreactive if which finding is noted on the electronic monitoring recording strip?

• A. Two fetal heart accelerations within a 20-minute period, peaking at 15 beats/min above baseline and lasting 15 seconds from baseline to baseline
• B. Accelerations without fetal movement with fetal heart rate (FHR) increases of 15 beats/min for 15 seconds
• C. Acceleration of the FHR by 25 to 30 beats/min for at least 15 seconds in response to fetal movement
• D. Absence of accelerations after fetal movement

Correct answer: D

Rationale: The correct answer is 'Absence of accelerations after fetal movement.' In a nonreactive (nonreassuring) stress test, the monitor recording would not show accelerations after fetal movement within a 40-minute period. This absence of accelerations indicates a nonreactive result. Choices A, B, and C describe different patterns of fetal heart rate accelerations that are not indicative of a nonreactive result in a nonstress test, making them incorrect. Choice A describes the characteristics of a reactive (reassuring) result, where there should be at least two fetal heart accelerations within a 20-minute period, peaking at least 15 beats/min above the baseline, and lasting 15 seconds from baseline to baseline. Choice B incorrectly states 'Accelerations without fetal movement,' which is contradictory. Choice C describes an acceleration response to fetal movement, which does not signify a nonreactive result.

4. When assessing Mr. Lee's eye condition, what general information should the nurse seek?

• A. Type of employment.
• B. Burning or itchy sensation in the eyes.
• C. Position of the eyelids.
• D. Existence of floaters.

Correct answer: A

Rationale: When assessing a patient's eye condition, the nurse should seek general information such as the type of employment, activities, allergies, medications, lenses, and protective devices used. This information helps in understanding potential exposures to irritants and risks related to activities. While the presence of burning or itchy sensation in the eyes, position of the eyelids, and existence of floaters are important aspects to assess during a focused eye examination, during the initial assessment, the type of employment is more relevant for understanding possible environmental factors affecting eye health.

5. A nurse assisting with data collection of the peripheral vascular system performs the Allen test. The nurse understands that this test is used to determine the patency of which blood vessel(s)?

• A. Capillaries
• B. Pedal pulses
• C. Femoral arteries
• D. Radial and ulnar arteries

Correct answer: D

Rationale: The nurse performs the Allen test to determine the patency of the radial and ulnar arteries. During the test, the nurse applies pressure over the client's ulnar and radial arteries simultaneously. The client is then asked to open and close the hand repeatedly, causing the hand to blanch. Subsequently, the nurse releases pressure from the ulnar artery while compressing the radial artery and checks the color of the extremity distal to the pressure point. If pinkness fails to return within 6 seconds, it indicates that the ulnar artery is insufficient, suggesting that the radial artery should not be used for obtaining a blood specimen. Choice A (Capillaries) is incorrect as the Allen test assesses the patency of larger arteries, not capillaries. Choice B (Pedal pulses) is incorrect as the Allen test specifically evaluates the radial and ulnar arteries, not the pedal pulses in the foot. Choice C (Femoral arteries) is incorrect as the Allen test focuses on the radial and ulnar arteries in the hand, not the femoral arteries in the leg.
