Correct Answer: C

Rationale: The correct method for teaching a client to use a cane when they have left-leg weakness is to maintain two points of support on the floor at all times. This approach ensures stability and helps the client maintain balance while using the cane. Choice A is incorrect because the cane should be used on the stronger side of the body to provide additional support. Choice B is incorrect as advancing the cane and the strong leg together may compromise stability. Choice D is incorrect as advancing the cane too far with each step can lead to imbalance and falls.

Correct Answer: D

Rationale: In a situation where a verbal prescription for restraints is obtained for a client experiencing acute mania, the nurse should document the client's condition every 15 minutes. This frequent documentation allows for accurate monitoring of the client's condition, ensuring safety and compliance. Requesting a renewal of the prescription every 8 hours (Choice A) is not necessary as the focus should be on monitoring the client's condition. Checking the client's peripheral pulse rate every 30 minutes (Choice B) is not directly related to the need for restraints in this scenario. Obtaining a prescription for restraint within 4 hours (Choice C) is not a priority when a verbal prescription is already obtained and immediate action is needed for the client's safety.

Correct Answer: A

Rationale: The correct answer is A. In older adults, key signs of a UTI often include confusion and increased temperature. Confusion is a common symptom in the elderly when they have a UTI, and an increase in body temperature can indicate an infection. Choices B, C, and D are incorrect because while painful urination and frequent urination are common UTI symptoms in general, they may not be as prominent in older adults. Dizziness, headache, back pain, and fever can be associated with other conditions but are not typically key signs of a UTI in older adults.

Correct Answer: D

Rationale: All of the above options are essential in preventing deep vein thrombosis (DVT) in post-operative patients. Encouraging early ambulation helps prevent blood stasis in the lower extremities, reducing the risk of DVT. Administering anticoagulants can prevent blood clots from forming. Compression stockings promote blood flow, reducing the likelihood of clot formation. Each intervention plays a crucial role in DVT prevention, making the correct answer 'All of the above.' Choices A, B, and C are not exclusive of each other but rather work synergistically to provide comprehensive prevention against DVT.

Correct Answer: A

Rationale: The correct answer is A: Monitor fluid balance and administer heparin. For a patient undergoing dialysis, it is crucial to monitor fluid balance to prevent fluid overload or depletion. Administering heparin helps prevent clot formation during the dialysis process. Option B is incorrect as while monitoring blood pressure is essential, preventing clot formation is more directly related to heparin administration. Option C is incorrect because administering medications and monitoring blood chemistry are not the primary interventions for dialysis. Option D is incorrect as while dietary education and protein intake are important for overall health, they are not the key nursing interventions specifically for a patient undergoing dialysis.
