A nurse is providing information to a group of pregnant clients and their partners about the psychosocial development of an infant. Using Erikson's theory of psychosocial development, the nurse tells the group that infants have which developmental need?

Correct Answer: B

Rationale: According to Erikson's theory of psychosocial development, infants struggle to establish a sense of basic trust rather than a sense of basic mistrust in their world, their caregivers, and themselves. If provided with consistent satisfying experiences that are delivered in a timely manner, infants come to rely on the fact that their needs are met and that, in turn, they will be able to tolerate some degree of frustration and discomfort until those needs are met. This sense of confidence is an early form of trust and provides the foundation for a healthy personality. Therefore, options A, C, and D are incorrect as they do not align with Erikson's theory that emphasizes the importance of infants trusting that their needs will be met.

Correct Answer: B

Rationale: The correct answer is to give the medications sequentially and flush well between them. Ampicillin has a pH of 8-10, while gentamicin has a pH of 3-5.5, making them incompatible when given together. Flushing well between drugs is necessary to prevent any potential interactions. Option A is incorrect because administering both medications simultaneously can lead to incompatibility issues. Option C is incorrect because the nurse should already be aware of the correct administration sequence and not need to consult the physician or pharmacy each time. Option D is incorrect because delaying the second medication by several hours can slow down the treatment of the client's infection, which is not ideal in this scenario.

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: 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.

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.
