Nursing Elites

1. The LPN is caring for a client newly diagnosed with HIV. Which statement made by the client regarding antiretroviral therapy (ART) would require correction from the nurse?

• A. "If I start ART and use condoms, I'm less likely to transmit HIV to my partner."?
• B. "I can still use ART even though I am Hepatitis C positive."?
• C. "I will need to be on ART indefinitely."?
• D. "I know I will need to come back for blood draws so that I can begin ART when my CD4 count is over 1,000 cells/mm3."?

Correct answer: D

Rationale: The correct answer is the statement, "I know I will need to come back for blood draws so that I can begin ART when my CD4 count is over 1,000 cells/mm3."? This statement would require correction from the nurse because initiating ART when the CD4 count is over 1,000 cells/mm3 is not supported by guidelines. The World Health Organization (WHO) recommends making treatment a priority for those with a CD4 count of ?350 cells/mm3, as early intervention can help delay disease progression. Therefore, waiting for a CD4 count of over 1,000 cells/mm3 is not in line with current recommendations. Choice A is correct, as studies have shown that using condoms along with ART can significantly reduce the risk of HIV transmission to sexual partners. Choice B is also correct because being Hepatitis C positive does not contraindicate the use of ART. Choice C is correct as well, as ART is typically needed indefinitely to maintain viral suppression and manage HIV. Therefore, the only statement that would require correction is Choice D.

2. 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.

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

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

Correct answer: B

Rationale: The correct answer is 'eggs.' Eggs are considered a complete protein as they contain all nine essential amino acids required by the body. On the other hand, corn, peanuts, and sunflower seeds are incomplete proteins, meaning they lack one or more of the essential amino acids needed by the body for optimal health. Corn, peanuts, and sunflower seeds are plant-based proteins that are deficient in one or more essential amino acids, unlike eggs, which are a high-quality complete protein source.

4. What causes an older female client's hair to turn gray?

• A. ''A loss of melanin occurs in the normal aging process.''
• B. ''The number of sweat glands and blood vessels decreases in the normal aging process.''
• C. ''The skin on the scalp becomes thin, causing moisture to escape.''
• D. ''It is caused by hereditary factors.''

Correct answer: A

Rationale: The correct answer is 'A loss of melanin occurs in the normal aging process.' Graying hair in older adults is primarily due to a decrease in the number of melanocytes responsible for providing pigment and hair color. This reduction in melanin production leads to gray hair. The other choices are incorrect. While it is true that the skin becomes thinner with aging and the number of sweat glands and blood vessels decreases, these changes are not directly related to graying hair. Additionally, hereditary factors can influence when graying starts, but they do not cause the graying of hair itself.

5. 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.
