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. During the examination of a client's throat, a nurse touches the posterior wall with a tongue blade and elicits the gag reflex. The nurse documents normal function of which cranial nerves?

• A. Cranial nerves V and VI
• B. Cranial nerves XII and VIII
• C. Cranial nerves XII and VIII
• D. Cranial nerves IX and X

Correct answer: D

Rationale: The correct answer is cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve). When the nurse touches the posterior pharyngeal wall with a tongue blade and elicits the gag reflex, it indicates normal function of these nerves. Cranial nerves V (trigeminal nerve) and VI (abducens nerve) are not directly responsible for the gag reflex. Cranial nerves XII (hypoglossal nerve) and VIII (vestibulocochlear nerve) are not directly involved in eliciting the gag reflex. Testing cranial nerve I involves smell function, and cranial nerve II is related to eye examinations, making them irrelevant in this scenario.

3. The mother of a newborn who was circumcised before discharge from the hospital calls the nurse at the pediatrician's office and tells the nurse that she is concerned because she has noticed a yellow crust over the circumcision site. The nurse provides which information to the mother?

• A. That it could indicate a sign of an infection and the infant's temperature should be checked every 2 hours
• B. That the crust is to be expected as a normal part of healing
• C. To bring the infant to the pediatrician's office to be checked
• D. To remove the crust, using a warm, wet face cloth and a mild soap

Correct answer: B

Rationale: After circumcision, a yellow crust may form over the circumcision site, which is a normal part of healing and should not be removed. The mother should be reassured that this crust is to be expected. Yellow crusting or discharge is not indicative of an infection, and there is no need to notify the pediatrician. Checking the infant's temperature every 2 hours is unnecessary and may cause unnecessary alarm to the mother.

4. After reviewing the child's immunization record, which scheduled vaccine should the nurse prepare to administer next?

• A. Hib
• B. IPV
• C. MMR
• D. DTaP

Correct answer: D

Rationale: The correct answer is DTaP. DTaP is administered at 2, 4, and 6 months of age; between 15 and 18 months of age; and between 4 and 6 years of age. Since the child has only received three doses of this vaccine, the next dose of DTaP should be administered. The other options are incorrect because Hib is administered at 2, 4, and 6 months of age and between 12 and 15 months; IPV is administered at 2, 4, and 6 months of age and between 4 and 6 years of age; MMR is administered between 12 and 15 months of age and again between 4 and 6 years of age.

5. 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.
