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 physical findings indicates that an 11-12-month-old child is at risk for developmental dysplasia of the hip?

• A. refusal to walk
• B. not pulling to a standing position
• C. negative Trendelenburg sign
• D. negative Ortolani sign

Correct answer: B

Rationale: The correct answer is 'not pulling to a standing position.' An 11-12-month-old child not pulling to a standing position may be at risk for developmental dysplasia of the hip. By this age, children typically pull to a standing position, and failure to do so should raise concerns. Refusal to walk is a broader observation and not specific to hip dysplasia. The Trendelenburg sign indicates weakness of the gluteus medius muscle, not hip dysplasia. The Ortolani sign is used to detect congenital subluxation or dislocation of the hip, which is different from developmental dysplasia of the hip.

3. When performing the confrontation test to assess peripheral vision, what action should the nurse take?

• A. Asks the client to identify a small object brought into the visual field
• B. Has the client cover one eye while the nurse covers one eye and slowly advances a target midline between them
• C. Covers one eye, while the client covers the opposite eye, and brings a small object into the visual field
• D. Positions at eye level with the client, covers one eye, and has the client cover the opposite eye, then brings a small object into the visual field

Correct answer: D

Rationale: When performing the confrontation test to assess peripheral vision, the nurse should position at eye level with the client, cover one eye, and have the client cover the opposite eye. This approach allows the examiner to bring a small object into the visual field to evaluate the client's peripheral vision. The test aims to compare the client's peripheral vision with the examiner's vision to identify any visual field deficits. Choices A, B, and C are incorrect. Choice A pertains to testing color vision, which is not part of the confrontation test. Choice B describes a different procedure that involves advancing a target midline between the client and examiner, not the correct approach for the confrontation test. Choice C is inaccurate as it fails to include the essential step of positioning at eye level with the client, making it an incorrect representation of the confrontation test.

4. The LPN is caring for a 9-month-old infant. Which of these behaviors exhibited by the child warrants further investigation?

• A. She prefers crawling over walking and makes no attempt to walk.
• B. She seems distressed by new adults.
• C. She does not respond to her own name.
• D. She only babbles "mama"? and "dada."?

Correct answer: C

Rationale: The correct answer is that the child does not respond to her own name. By 9 months, children should be babbling simple words, crawling, and responding to their name. Not responding to one's name can be an early indicator of a potential developmental delay, warranting further investigation. Preferring crawling over walking, being distressed by new adults, and babbling 'mama' and 'dada' are typical behaviors for a 9-month-old and do not necessarily require immediate concern.

5. 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.
