A nurse is assisting with data collection on the language development of a 9-month-old infant. Which developmental milestone does the nurse expect to note in an infant of this age?

Correct Answer: D

Rationale: An 8- to 9-month-old infant can string vowels and consonants together. The first words, such as 'Mama,' 'Daddy,' 'bye-bye,' and 'baby,' begin to have meaning. A 1- to 3-month-old infant produces cooing sounds. Babbling is common in a 3- to 4-month-old. Single-consonant babbling occurs between 6 and 8 months of age. Therefore, the milestone of the infant saying 'Mama' is the most appropriate for a 9-month-old, indicating early language development. The other choices are developmentally inaccurate for a 9-month-old infant.

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.

Correct Answer: B

Rationale: According to Erikson, the correct developmental task for a toddler who has developed 'a will of his own' and 'acts as if he can control others' is Autonomy versus doubt and shame. Toddlers at this stage are asserting their wills and realizing they can control others, which is part of developing autonomy. However, they may also experience doubt and shame if their assertiveness is met with disapproval. Trust versus mistrust is the developmental task of the infant, where the main focus is on developing trust in the caregiver. Initiative versus guilt is the developmental task of the preschool-age child, emphasizing the balance between taking initiative and feeling guilty. Industry versus inferiority is the developmental task of the school-age child, focusing on competence and self-esteem.

Correct Answer: D

Rationale: The best action for the nurse to take to help a hospitalized toddler maintain a sense of control and security and ease feelings of helplessness and fear is to keep hospital routines as similar as possible to those at home. By incorporating the toddler's usual rituals and routines from home into nursing care activities, the nurse can reduce the stress of hospitalization. This approach gives the toddler a sense of familiarity, control, and security, which can alleviate feelings of helplessness and fear. Allowing the toddler to play with other children in the nursing unit playroom and selecting toys are beneficial activities, but maintaining hospital routines similar to those at home is the most effective way to support the toddler's emotional well-being during hospitalization.

Correct Answer: D

Rationale: When educating an obese client about nutritional needs and weight loss, it is crucial to emphasize a holistic approach that involves understanding food and food products, fostering a positive mental attitude, and incorporating adequate exercise. Initiating a fast weight-loss diet is not advisable due to potential health risks and lack of long-term sustainability. Therefore, this option stands out as the exception and should not be part of the client's learning. Choices A, B, and C are essential components of a healthy weight-loss plan and should be included in the client's education.
