Correct Answer: B

Rationale: The correct answer is to establish a set routine for rising, hygiene, meals, short rest periods, and bedtime. By creating a structured daily schedule, the client's natural sleep-wake cycle can be regulated, helping to address the issue of daytime sleeping and nighttime wakefulness. Option A, asking for a strong sleep medicine, may not address the underlying cause and can have potential side effects in the elderly. Option C, engaging in exercises when drowsy, may not be suitable for someone with dementia and could disrupt sleep patterns further. Option D, promoting relaxation before bedtime, is helpful but may not be sufficient to address the client's significant sleep issue.

Correct Answer: D

Rationale: In resolving ethical dilemmas, it is essential to identify possible solutions to address the client care dilemma effectively. Option A, 'Ensure client autonomy only,' is not comprehensive enough to resolve complex ethical issues. Option B, 'Consider only medical benefits,' overlooks other important factors beyond medical benefits that are involved in ethical decision-making. Option C, 'Ensure clear communication among the health care team,' is important but may not be sufficient on its own to resolve the ethical dilemma. Therefore, the most effective strategy among the given options is to identify possible solutions to navigate through the ethical dilemma.

Correct Answer: A

Rationale: The correct answer is A: Pulmonary embolism and stroke. Untreated DVT can result in these serious complications, emphasizing the importance of timely intervention. Choices B, C, and D are incorrect because they do not represent common complications associated with untreated deep vein thrombosis. Infection and kidney failure, hypertension and vision loss, as well as dehydration and electrolyte imbalance are not typically direct consequences of untreated DVT.

Correct Answer: D

Rationale: The correct answer is to keep the cord stump dry until it falls off. This is important to promote natural healing and prevent infection. Choice A is incorrect because cleaning the cord with hydrogen peroxide daily can actually delay healing and increase the risk of infection. Choice B is incorrect as the cord stump typically falls off within 1 to 3 weeks, not in 5 days. Choice C is incorrect because a cord stump turning black is a normal part of the healing process and does not necessarily indicate a problem requiring immediate provider contact.

Correct Answer: B

Rationale: Performing fundal massage is the priority action in this scenario. Fundal massage helps contract the uterus, which is essential in reducing excessive lochia postpartum. Administering oxytocin may be indicated later, but fundal massage should be the initial intervention to address the issue. Administering IV fluids may not directly address the cause of excessive lochia, and calling the provider should come after implementing immediate nursing interventions.
