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: A

Rationale: Rehabilitation services should begin when the client enters the health care system to ensure early intervention and optimal outcomes. Initiating rehabilitation early can help prevent complications, improve recovery, and enhance overall well-being. Option B is incorrect because waiting for the client to request services may lead to delays in starting treatment, potentially affecting the recovery process. Option C is incorrect as rehabilitation can often commence even when the client's physical condition is not fully stabilized, as early intervention is crucial for progress. Option D is incorrect as beginning rehabilitation only after hospital discharge may not be ideal, as early intervention within the healthcare system is preferred for a more effective recovery journey.

Correct Answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, heparin sodium, is an anticoagulant and is not used for flushing IV devices before and after blood administration.

Correct Answer: A

Rationale: When discussing birth control methods with a client, a nurse should focus on the client's personal preference as a major factor that will provide the motivation needed for consistent implementation of a birth control method. Personal preference plays a key role in ensuring that the chosen method aligns with the client's lifestyle and values, increasing the likelihood of adherence. While work and home schedules, family planning goals, and the desire to have children in the future can influence the choice of birth control method, they are not the primary motivating factors for consistent implementation. Personal preference is crucial as it empowers the client to select a method that suits their individual needs and preferences, ultimately leading to better compliance and effectiveness.

Correct Answer: A

Rationale: The correct answer is varicella. Varicella vaccine contains a live, weakened form of the varicella-zoster virus. Choice B, IPV (inactivated poliovirus vaccine), is an inactivated vaccine, not a live virus vaccine. Choices C and D, DTaP (diphtheria, tetanus, and acellular pertussis vaccine) and hepatitis B vaccine, respectively, do not contain live viruses. Varicella is the only live virus vaccine among the options.
