Correct Answer: C

Rationale: When assessing language development in a toddler from a bilingual family, a nurse would expect the child's language development to be slower than expected. Various factors, such as physical maturity and reinforcement received, can influence the pace of language development. Children from bilingual families, twins, and non-firstborn children may exhibit slower language development. Therefore, it is common for the language development of a toddler from a bilingual family to be slower than expected. This characteristic does not necessarily imply a need for speech therapy. Choices A, B, and D are incorrect because, in this context, the language development of the child is more likely to be slower than expected rather than more advanced, developing as expected, or requiring speech therapy.

Correct Answer: C

Rationale: To confirm pregnancy, the presence of palpable fetal movement is a positive indicator. Palpable fetal movement is a certain sign of pregnancy, known as a fetal movement felt by the examiner. Amenorrhea is a presumptive sign of pregnancy as it is reported by the woman but is not confirmatory. Thinning of the cervix (Hegar sign) is a probable sign of pregnancy, which is not confirmatory. A positive result on a home urine test for pregnancy is also a probable indicator. However, a positive pregnancy test result can sometimes yield false-positive results due to various factors like medication, recent pregnancy, or errors in reading.

Correct Answer: C

Rationale: In later adulthood, age-related findings include trophic changes associated with arterial insufficiency, such as thin, shiny skin; thin, ridged toenails; and loss of hair on the lower legs. These changes occur normally with aging. Thick skin on the lower legs would not be an expected age-related finding as it typically indicates chronic venous insufficiency. A bounding dorsalis pedis pulse is not typical in later adulthood and may indicate arterial insufficiency, which is not an age-related finding.

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: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.
