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. Central venous access devices (CVADs) are frequently utilized to administer chemotherapy. What is an advantage of using CVADs for chemotherapeutic agent administration?

• A. CVADs are more expensive than a peripheral IV.
• B. Weekly administration is possible.
• C. Chemotherapeutic agents can be caustic to smaller veins.
• D. The client or family can administer the drug at home.

Correct answer: C

Rationale: The correct advantage of using CVADs for chemotherapeutic agent administration is that chemotherapeutic agents can be caustic to smaller veins. Many chemotherapeutic drugs are vesicants, which can cause tissue damage even in low concentrations. Using a CVAD to administer these agents into a large vein is optimal as it reduces the risk of damage. Choice A is incorrect as CVADs are actually more expensive than a peripheral IV, making it a disadvantage. Choice B is incorrect because the frequency of administration depends on the specific drug being administered, not on the access device, so it does not represent a universal advantage. Choice D is incorrect because IV chemotherapeutic agents are typically not self-administered at home; they are usually given in a hospital, outpatient, or clinic setting, making it an invalid advantage of using CVADs.

3. As part of a routine health screening, the nurse notes the play of a 2-year-old child. Which of the following is an example of age-appropriate play at this age?

• A. builds towers with several blocks
• B. tries to color within the lines
• C. says 'Mine!' when playing with toys
• D. tries to jump rope

Correct answer: C

Rationale: The correct answer is C: 'says 'Mine!' when playing with toys.' At the age of 2, children are in the stage of parallel play and are possessive of their belongings, hence saying 'Mine!' is an age-appropriate behavior. Building towers with blocks (choice A) involves more advanced motor skills and cognitive abilities, which are beyond what most 2-year-olds can do. Trying to color within the lines (choice B) requires fine motor skills that are typically not developed at age 2. Jumping rope (choice D) involves coordination and balance that are beyond the capabilities of a 2-year-old child.

4. 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.

5. 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.
