Correct Answer: B

Rationale: The correct teaching point for a client with left-leg weakness learning to use a cane is to maintain two points of support on the floor at all times. This ensures better stability and support for the client while walking. Choice A is incorrect because the cane should be used on the stronger side to support the weaker leg. Choice C is incorrect as advancing the cane too far with each step may compromise balance. Choice D is incorrect because advancing the cane and the strong leg together may not provide adequate support for the weaker leg.

Correct Answer: B

Rationale: The correct answer is B. Ethical dilemmas involve conflicting values or feelings. In this situation, the family is conflicted about tube feeding for their terminally ill father, which presents a moral and ethical challenge. Choices A, C, and D do not represent ethical dilemmas. Choice A involves a nurse's impairment, which is a different issue. Choice C involves a nurse's observation of a colleague's threat, which is a patient safety concern. Choice D involves a client's hesitation in naming a spouse as power of attorney, which is a legal and decision-making issue, not necessarily an ethical dilemma.

Correct Answer: D

Rationale: The correct answer is to apply ice to the affected knee for 24-48 hours. Applying ice helps to reduce inflammation and pain after knee surgery, promoting healing. Choice A is incorrect because heat is not recommended postoperatively, as it can increase swelling. Choice B is incorrect because pillows should be placed under the knee to keep it elevated. Choice C is incorrect because early mobilization is essential for preventing complications such as blood clots.

Correct Answer: B

Rationale: The correct answer is B. The client's frustration with opening a milk carton indicates difficulty with activities of daily living, which is a common concern addressed by occupational therapists. Choices A, C, and D are related to fine motor skills, which may also be addressed by an occupational therapist but are not as directly linked to activities of daily living as struggling with tasks like opening containers.

Correct Answer: A

Rationale: Corrected DVT management involves administering anticoagulants to prevent clot growth and monitoring for signs of bleeding. Elevating the limb and administering pain relief (Choice B) may help alleviate symptoms but do not address the underlying issue of preventing clot progression. Restricting mobility and applying warm compress (Choice C) could potentially dislodge the clot and worsen the condition. Administering IV fluids and providing bed rest (Choice D) are not primary interventions for managing DVT.
