Correct Answer: B

Rationale: To assess the fetal heart rate of a client who is 14 weeks pregnant, the nurse should use a Doppler transducer. Fetal heart sounds can be heard with a fetoscope by 20 weeks of gestation. The Doppler transducer amplifies fetal heart sounds so that they are audible by 10 to 12 weeks of gestation, making it the most appropriate choice for this scenario. Fetal heart sounds cannot be heard with a stethoscope. Pulse oximetry is not used to auscultate fetal heart sounds, so it is an incorrect choice in this context.

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: B

Rationale: In the African American family structure, the woman, especially the mother, often plays a central role in healthcare decisions and maintaining family health. It is essential for the nurse to involve the client's mother in teaching him about his prescribed medications as she may be responsible for his care and treatment decisions. While other family members may also be involved, the African American family is often matrifocal, emphasizing the importance of the mother's role. Therefore, it is crucial for the nurse to ensure the client's mother is present during medication teaching. Choices A, C, and D are incorrect as they do not align with the traditional African American family structure and the role of women in healthcare decisions.

Correct Answer: D

Rationale: The correct answer is medication instruction. This is a skilled service that requires specialized knowledge and training to provide proper guidance on medication management for a client with type I diabetes. Grocery shopping, house cleaning, and transportation services are considered unskilled services as they are typically offered by volunteer or fee-for-service agencies and do not require specialized medical expertise. Medication instruction, on the other hand, involves educating the client on how to properly take medications, understand potential side effects, and manage their medication regimen effectively, which necessitates a high level of expertise and training.

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.
