Correct Answer: A

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 ground at all times. This ensures stability and helps prevent falls. Choice B, using the cane on the weak side of the body, may lead to imbalance and decreased support. Choice C, advancing the cane a specific distance with each step, is not as crucial as maintaining two points of support. Choice D, advancing the cane and the strong leg simultaneously, may also compromise stability and support for the weak leg.

Correct Answer: A

Rationale: Shortness of breath is the main symptom of left-sided heart failure because it results from pulmonary congestion due to fluid buildup in the lungs. Edema, increased heart rate, and decreased urine output are associated with right-sided heart failure rather than left-sided heart failure.

Correct Answer: A

Rationale: Encouraging oral fluid intake is a crucial nursing intervention in managing a patient with fluid volume deficit. By encouraging oral fluid intake, the patient can increase hydration levels, helping to correct the deficit. Administering IV fluids may be necessary in severe cases or when the patient is unable to tolerate oral intake. Monitoring urine output and checking electrolyte levels are essential aspects of assessing fluid volume status, but they are not direct interventions for correcting fluid volume deficit. Monitoring skin turgor and capillary refill are important assessments for fluid volume status but are not direct management strategies.

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: D

Rationale: The most important intervention for a client with rheumatoid arthritis is to assist with heat application and range of motion exercises. Heat application helps reduce stiffness and improve joint flexibility, while range of motion exercises help maintain mobility and prevent contractures. Massaging inflamed joints with creams and oils may provide temporary relief but does not address the root cause of stiffness and limited mobility in rheumatoid arthritis. Providing support to flexed joints with pillows and pads can be helpful for comfort but does not actively promote mobility. Positioning the client on their abdomen several times a day is not a standard intervention for managing rheumatoid arthritis.
