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. A nurse is preparing to test the function of cranial nerve XI. Which action does the nurse take to test this nerve?

• A. Asking the client to stick out his or her tongue and watching for tremors
• B. Touching the posterior pharyngeal wall with a tongue blade and noting the gag reflex
• C. Depressing the client's tongue with a tongue blade and noting pharyngeal function as the client says 'ah'
• D. Placing his or her hands on the client's shoulders and asking the client to shrug the shoulders against resistance from the nurse's hands

Correct answer: D

Rationale: To assess the function of cranial nerve XI (spinal accessory nerve), the nurse examines the sternomastoid and trapezius muscles for equal size and strength. The correct method involves asking the client to rotate the head forcibly against resistance to the side of the chin and to shrug the shoulders against resistance from the nurse's hands. Choice A, asking the client to stick out the tongue and watching for tremors, is used to assess cranial nerve XII (hypoglossal nerve). Choice C, depressing the client's tongue with a tongue blade and noting pharyngeal function as the client says 'ah', is the technique for examining cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve). Choice B, touching the posterior pharyngeal wall with a tongue blade and noting the gag reflex, is used to evaluate cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve), not cranial nerve XI.

3. A nurse in the emergency department is assisting with data collection of a client. The presence of which condition would cause the nurse to avoid testing range of motion (ROM) of the cervical spine?

• A. Headache
• B. Neck trauma
• C. Sinus infection
• D. Muscle spasms

Correct answer: B

Rationale: A nurse assisting with data collection for a client should avoid testing the range of motion (ROM) of the cervical spine if the client has neck trauma. Neck trauma may have resulted in a cervical fracture, and further movement of the neck could lead to spinal cord injury. Testing ROM does not need to be avoided for headache, sinus infection, or muscle spasms as these conditions do not pose the same risk of exacerbating a potential cervical injury. Therefore, the correct answer is neck trauma.

4. A client with massive chest and head injuries is admitted to the ICU from the Emergency Department. All of the following are true except:

• A. The physician in charge of the case is the sole person allowed to decide whether organ donation can occur.
• B. The client's legally responsible party may make the decision for organ donation for the donor if the client is unable to do so.
• C. The organ procurement organization makes the decision regarding which organs to harvest.
• D. The donor (or legally responsible party for the donor), the physician, and the organ-procurement organization are all involved in the process.

Correct answer: A

Rationale: While the physician plays a crucial role in the process of organ donation, they are not the sole decision-maker. The client's legally responsible party may make the decision for organ donation if the client is unable to do so. Additionally, the organ procurement organization is responsible for determining which organs are suitable for donation. Therefore, the statement that the physician in charge is the sole person allowed to decide whether organ donation can occur is incorrect. The correct answer is A. Choices B, C, and D are true statements as they highlight the involvement of the legally responsible party, the organ procurement organization, and the donor/legally responsible party, physician, and organ-procurement organization in the organ donation process respectively.

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.
