Nursing Elites

1. 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.

2. Which of the following foods is a complete protein?

• A. corn
• B. eggs
• C. peanuts
• D. sunflower seeds

Correct answer: B

Rationale: Eggs are considered a complete protein because they contain all nine essential amino acids required by the human body. In contrast, corn, peanuts, and sunflower seeds are incomplete proteins as they lack one or more essential amino acids. Corn, although a staple food for many cultures, is deficient in the amino acids lysine and tryptophan. Peanuts are low in the amino acid methionine, and sunflower seeds are low in lysine. Therefore, eggs are the correct answer as a complete protein source.

3. A client with peripheral artery disease tells the nurse that pain develops in his left calf when he is walking and subsides with rest. The nurse documents that the client is most likely experiencing which disorder?

• A. Venous insufficiency
• B. Intermittent claudication
• C. Sore muscles from overexertion
• D. Muscle cramps related to musculoskeletal problems

Correct answer: B

Rationale: Leg pain characteristic of peripheral artery disease is known as intermittent claudication. The client can walk only a certain distance before cramping, burning, muscle discomfort, or pain forces them to stop, with the pain subsiding after rest. The pain is reproducible, and as the disease progresses, the client can walk shorter distances before the pain recurs. Ultimately, pain may even occur at rest. Venous insufficiency (Choice A) involves impaired blood flow in the veins, leading to swelling and skin changes but not typically pain associated with exercise. Sore muscles from overexertion (Choice C) and muscle cramps related to musculoskeletal problems (Choice D) do not present with the characteristic pattern of pain associated with peripheral artery disease.

4. 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.

5. How should a client's neck be positioned for palpation of the thyroid?

• A. flexed toward the side being examined
• B. hyperextended directly backward
• C. flexed away from the side being examined
• D. flexed directly forward

Correct answer: A

Rationale: The correct way to position a client's neck for palpation of the thyroid is to have it flexed toward the side being examined. This positioning helps to better access and palpate the thyroid gland. Option B, hyperextending the neck directly backward, is incorrect as it can make palpation more difficult and uncomfortable for the client. Option C, flexing the neck away from the side being examined, is also incorrect as it may obscure the thyroid gland, making it harder to palpate. Option D, flexing the neck directly forward, is not ideal for thyroid palpation as it does not provide the best access to the gland.
