Central venous access devices (CVADs) are frequently utilized to administer chemotherapy. What is an advantage of using CVADs for chemotherapeutic agent administration?

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: The correct answer is 'Aunts, uncles, grandparents, and cousins.' When gathering medical history from the client's extended family, it is essential to inquire about relatives beyond the nuclear family, such as aunts, uncles, grandparents, and cousins, as they share genetic and environmental influences. Choice C, 'Wife's children from a previous marriage,' pertains to stepchildren, not extended family members. Choice B, 'Foster children and their parents,' involves individuals who are not biologically related to the client's family. Choice D, 'Wife and wife's parents,' focuses solely on immediate family members and excludes the client's extended family members, which are crucial for a comprehensive health assessment.

Correct Answer: D

Rationale: A client can receive the MMR vaccine if he or she has a cold without a fever since it does not preclude vaccination. Pregnant women and immunocompromised individuals cannot receive the MMR vaccine because the rubella component is a live virus that may cause birth defects and/or disease. Being allergic to neomycin is also a contraindication as per the American Academy of Pediatrics guidelines. Individuals who have experienced anaphylactic reactions to neomycin should not receive the measles vaccine. Therefore, option D 'has a cold' is the correct choice, as the presence of a simple cold does not prevent the client from receiving the MMR vaccine.

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: 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.
