Which of the following interventions is most appropriate for a client with left-leg weakness who is learning to use a cane?

Correct Answer: A

Rationale: The most appropriate intervention 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 stability and helps distribute weight evenly between the legs, reducing the risk of falls. Using the cane on the weak side of the body (Choice B) may not provide adequate support. Advancing the cane and the strong leg simultaneously (Choice C) can lead to imbalance and increases the risk of falls. Advancing the cane too far with each step (Choice D) can also compromise balance and stability.

Correct Answer: B

Rationale: The best strategy for managing dehydration in a client is to monitor fluid and electrolyte levels frequently. This allows healthcare providers to assess the client's hydration status accurately and make informed decisions regarding treatment. Encouraging the client to drink more water (Choice A) may not be sufficient if the dehydration is severe and requires specific interventions. Administering oral rehydration solutions (Choice C) can be beneficial but should be guided by monitoring the client's condition. Increasing the IV fluid rate (Choice D) may be necessary in certain cases, but it is not always the initial or best approach, as monitoring is crucial to avoid fluid and electrolyte imbalances.

Correct Answer: B

Rationale: The correct answer is B: Ensure the blood type is compatible with the client. This is the most crucial step in preparing for a blood transfusion to prevent severe transfusion reactions. Checking the client for a fever (Choice A) is important but not the most critical step. Administering blood via IV push (Choice C) is incorrect as blood transfusions are usually administered as a slow drip. Warming the blood to body temperature (Choice D) is not a standard practice and can lead to hemolysis, making it an incorrect choice.

Correct Answer: D

Rationale: The correct answer is D. New onset of tachypnea indicates a potential respiratory complication that requires immediate attention. Assessing the client with a hip fracture and tachypnea first is crucial to address the respiratory issue and prevent further deterioration. Choices A, B, and C do not present immediate life-threatening complications that require urgent assessment compared to a new onset of tachypnea.

Correct Answer: B

Rationale: The correct answer is B: Fever. Fever in a postoperative client can indicate an infection, which is a serious complication and should be reported immediately to the provider for further evaluation and management. Clear lung sounds (Choice A) are a positive finding indicating normal respiratory function. Pain in the operative leg (Choice C) is expected postoperatively and should be managed with appropriate pain relief measures. Capillary refill of 2 seconds (Choice D) is within the normal range (less than 3 seconds) and is not a concerning finding postoperatively.

Correct Answer: D

Rationale: The correct action the nurse should take when administering enoxaparin subcutaneously is to pinch the skin between the thumb and forefinger. Pinching the skin helps to lift the subcutaneous tissue, reducing the risk of injecting into the muscle. Choices A, B, and C are incorrect. Choice A is not relevant as the injection site for enoxaparin is typically in the abdomen or thigh, not the arm. Choice B is incorrect as pulling the skin laterally is not a recommended technique for subcutaneous injections. Choice C is also incorrect as massaging the injection site after administration can increase the risk of bleeding or bruising.

Correct Answer: A

Rationale: The correct adverse effect that the nurse should include in the teaching is fatigue. Fatigue is a common side effect of radiation therapy, particularly with prolonged treatment. Constipation, hair loss, and weight gain are not typically associated with radiation therapy for breast cancer, making them incorrect choices. Fatigue can significantly impact a patient's quality of life during treatment and should be addressed proactively by healthcare providers.

Correct Answer: C

Rationale: Placing a pillow between the client's legs is beneficial after hip replacement surgery to maintain proper alignment and prevent dislocation of the prosthesis. This position helps keep the hip in a neutral position, reducing the risk of dislocation. Encouraging the client to bend at the waist (Choice A) can increase the risk of hip dislocation. Maintaining the client in a high-Fowler's position (Choice B) and avoiding placing a pillow under the client's knees (Choice D) do not directly address the need to maintain proper alignment of the hip joint to prevent dislocation.

Correct Answer: B

Rationale: Myxedema is characterized by a decreased metabolic rate, leading to manifestations such as decreased temperature. Therefore, the correct assessment finding expected with myxedema is a decreased temperature. Choices A, C, and D are incorrect because myxedema typically presents with a decreased pulse rate, not an increased pulse rate, absence of fine tremors (which are more common in hyperthyroidism), and weight gain rather than weight loss.
