Correct Answer: C

Rationale: The correct answer is C. Using echolalia, which is the repetition of words or phrases, is not typical for a 2-year-old child and may indicate the need for further evaluation. Choices A, B, and D are all within the expected developmental skills for a 2-year-old. While most 2-year-olds may not be able to stand on one foot, it is not a cause for concern at this age. Building a tower of 7 blocks and coloring outside the lines of a picture are both appropriate for a 2-year-old's developmental skills.

Correct Answer: D

Rationale: In hypospadias, the urethral opening is located along the ventral surface of the penis. This congenital condition results in the urethral meatus opening on the underside of the penis, rather than at the tip. Choice A is incorrect as there is typically a urethral opening present, though in an abnormal location. Choice B is not a characteristic feature of hypospadias. Choice C is incorrect as the urethral opening in hypospadias is not along the dorsal surface but rather along the ventral surface of the penis.

Correct Answer: C

Rationale: The correct behavior that the nurse needs to prevent postoperatively is straining at stool. Straining at stool should be avoided as it can increase intrathoracic pressure, leading to stress on the surgical site. This stress can potentially compromise the surgical repair and increase the risk of complications. Crying, coughing, and unnecessary movement, although important to monitor postoperatively, do not directly impact the surgical site as significantly as straining at stool does. Therefore, the focus should be on preventing straining at stool to ensure the best postoperative outcome for the child.

Correct Answer: A

Rationale: When a child with diabetes insipidus is treated with vasopressin, the nurse should closely monitor for signs and symptoms of Syndrome of Inappropriate Antidiuretic Hormone (SIADH). Vasopressin, also known as antidiuretic hormone, helps retain water in the body. Excessive vasopressin administration can lead to water retention, dilutional hyponatremia, and potentially result in SIADH. Choices B, C, and D are incorrect because they are not directly associated with the use of vasopressin in treating diabetes insipidus.

Correct Answer: B

Rationale: Breastfeeding is the best recommendation to help prevent constipation in infants. Breast milk is easily digestible and contains the right balance of nutrients, which can lead to softer stools, thus reducing the likelihood of constipation. Offering a soy formula (Choice A) may not necessarily prevent constipation as effectively as breast milk due to differences in nutrient composition. Administering a suppository nightly (Choice C) is not a routine measure for preventing constipation in infants and may not be suitable for regular use in this scenario. Offering glucose water (Choice D) between feedings is not recommended as it does not provide the necessary nutrients found in breast milk, which are essential for preventing constipation and promoting overall health in newborns.
