Nursing Elites

1. 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.

2. 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.

3. What is the most appropriate initial action for a newborn infant with low blood glucose?

• A. Ask the registered nurse to draw another blood sample in 2 hours and repeat the test
• B. Contact the healthcare provider
• C. Contact the registered nurse
• D. Document the results in the newborn's medical record

Correct answer: C

Rationale: The blood glucose level for a newborn infant should remain greater than 40 mg/dL to prevent permanent brain damage. When dealing with low blood glucose in a newborn, the most appropriate initial action is to contact the registered nurse. The nurse will obtain prescriptions regarding feeding the infant with low blood glucose and follow agency policies on feeding infants in such conditions. It is common practice to feed the infant if the glucose level is 40 mg/dL or less. Asking the registered nurse to draw another blood sample in 2 hours and repeating the test is not the most appropriate immediate action, as timely intervention is crucial in this situation. Contacting the healthcare provider may cause unnecessary delays since the registered nurse is usually the first point of contact for immediate actions in this scenario. Documenting the results in the newborn's medical record is essential, but it is not the initial step in managing low blood glucose in a newborn.

4. Which of the following home-care strategies is most likely to negatively impact the body image of a client with Cushing's syndrome?

• A. providing safety measures to prevent falls
• B. taking medications as prescribed
• C. wearing a medical ID indicating Cushing's syndrome
• D. having regular health assessments

Correct answer: C

Rationale: All of the strategies listed are essential components of home care for a client with Cushing's syndrome. However, wearing a medical ID indicating Cushing's syndrome is the correct answer as it can have a negative impact on body image. This choice may constantly remind the client of their condition, potentially affecting their self-image and confidence. On the contrary, providing safety measures to prevent falls (Choice A) would enhance body image by promoting safety and preventing injuries. Taking medications as prescribed (Choice B) is likely to improve body image by managing symptoms effectively. Having regular health assessments (Choice D) demonstrates good self-care and can positively contribute to body image by showing a commitment to maintaining health.

5. A nurse in a day-care setting is planning play activities for 2- and 3-year-old children. Which toys are most appropriate for these activities?

• A. Finger paints and card games
• B. Blocks and push-pull toys
• C. Videos and cutting-and-pasting toys
• D. Simple board games and puzzles

Correct answer: B

Rationale: The most appropriate toys for 2- and 3-year-old children in a day-care setting are blocks and push-pull toys. Toddlers enjoy objects of different textures like clay, sand, finger paints, and bubbles, as well as push-pull toys, large balls, and sand and water play. They also like activities such as blocks, painting, coloring with large crayons, large puzzles, and playing with trucks or dolls. Finger paints and card games may be more suitable for older children. Videos and cutting-and-pasting toys are generally more appropriate for preschoolers. Blocks and push-pull toys are beneficial for young children as they help in developing fine motor skills, hand-eye coordination, spatial awareness, and creativity. These toys also encourage imaginative play and problem-solving, making them ideal choices for toddlers.
