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.

A nurse is conducting a psychosocial assessment of a young adult. Which observations would lead the nurse to determine that the client is demonstrating a sign of emotional health?
- A. The young adult is sensitive to criticism.
- B. The young adult verbalizes unrealistic fears.
- C. The young adult verbalizes disappointment with life.
- D. The young adult verbalizes satisfaction with friendships.
Correct Answer: D
Rationale: The correct answer is that the young adult verbalizes satisfaction with friendships. Emotional health in young adults is characterized by various positive signs, including satisfaction with social interactions and friendships. Expressing contentment with friendships indicates a healthy emotional state, fostering positive social connections. On the other hand, sensitivity to criticism, verbalizing unrealistic fears, and expressing disappointment with life are all indicative of emotional distress and potential mental health challenges. These behaviors can hinder social relationships and overall emotional well-being.
The mother of a toddler asks the nurse when she will know that her child is ready to start toilet training. The nurse tells the mother that which observation is a sign of physical readiness?
- A. The child no longer has temper tantrums.
- B. The child can remove his or her own clothing.
- C. The child has been walking for 2 years.
- D. The child can eat using a fork and knife.
Correct Answer: B
Rationale: Signs of physical readiness for toilet training include the child's ability to remove his or her own clothing. This ability indicates the child has developed the necessary fine motor skills to manage clothing during toilet training. The other choices are incorrect because temper tantrums, walking for a specific period, and using utensils are not indicators of physical readiness for toilet training.
A teenager is preparing to care for a hospitalized teenage girl who is in skeletal traction. The teenager assists with planning care knowing that which is the most likely primary concern of the teenage girl?
- A. Keeping up with schoolwork
- B. Body image
- C. Obtaining adequate rest and sleep
- D. Obtaining adequate nutrition
Correct Answer: B
Rationale: The correct answer is 'Body image.' Adolescents, especially teenage girls, are often preoccupied with their appearance and body image. When facing a situation like being in skeletal traction, which can affect their physical appearance, body image becomes a primary concern. Concerns about body image can significantly impact their self-esteem and emotional well-being. Choice A, 'Keeping up with schoolwork,' is important but typically not the primary concern in this context. Choices C and D, 'Obtaining adequate rest and sleep' and 'Obtaining adequate nutrition,' are crucial for overall health but are secondary to the significant impact that body image concerns can have on a teenage girl in this situation.
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.
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: For a 2-year-old child, saying 'Mine!' when playing with toys is an example of age-appropriate play. Toddlers at this age are possessive and asserting their sense of ownership. Building towers with blocks and trying to color within the lines involve more advanced motor skills and cognitive abilities that are typically not fully developed in a 2-year-old. Jumping rope requires coordination and balance beyond what a 2-year-old can usually achieve. Therefore, choices A, B, and D are not considered age-appropriate plays for a 2-year-old child.
