Correct Answer: A

Rationale: Choice A is correct because performing ankle and knee exercises every hour helps prevent contractures and other adverse effects of immobility. Contractures are a common complication of immobility, and range of motion (ROM) exercises can help maintain joint flexibility and prevent contractures. This statement indicates an understanding of the teaching provided by the healthcare provider. Choices B, C, and D are incorrect. Holding the breath when rising from a sitting position can increase the risk of orthostatic hypotension, not reduce adverse effects of immobility. Removing antiembolic stockings while in bed can compromise their effectiveness in preventing deep vein thrombosis (DVT), which is not a measure to reduce immobility-related complications. Having a partner help change positions every 4 hours may not be frequent enough to prevent immobility-related complications effectively; changing positions more frequently is usually recommended to prevent issues like pressure ulcers and muscle stiffness.

Correct Answer: A

Rationale: The most critical action for the nurse to take when a client with diabetes mellitus presents with symptoms of hyperglycemia such as polyuria, polydipsia, and polyphagia is to monitor the client's blood glucose level. This action helps in assessing the client's current glycemic status and guides further interventions. Encouraging increased fluid intake (Choice B) may be beneficial in managing dehydration caused by polyuria, but it does not address the underlying cause of hyperglycemia. Administering insulin as prescribed (Choice C) may be necessary based on the blood glucose monitoring results, but monitoring should precede any medication administration. Assessing the client's urine output (Choice D) is important but does not directly address the primary concern of evaluating and managing hyperglycemia in a client with diabetes.

Correct Answer: A

Rationale: The pulse deficit is calculated by finding the difference between the apical and radial pulse rates. In this case, the difference is 84 - 68 = 16. This indicates that there is a pulse deficit of 16 beats per minute. Choices B, C, and D are incorrect as they do not accurately reflect the difference between the two pulse rates.

Correct Answer: A

Rationale: Monitoring hourly urine output is crucial after successful resuscitation from a pulseless dysrhythmia to assess kidney function and perfusion. The kidneys are particularly vulnerable to injury following cardiac events due to decreased perfusion during the event. Evaluating urine output hourly allows for early detection of renal impairment or inadequate organ perfusion. Option B, monitoring white blood cell count, is not a priority in this situation as it does not directly relate to immediate post-resuscitation care. Option C, checking blood glucose every 4 hours, is important but not as critical as assessing kidney function and perfusion. Option D, measuring temperature every 2 hours, is relevant for monitoring signs of infection or inflammatory response but is not as crucial as assessing kidney function in this scenario.

Correct Answer: A

Rationale: Weight loss is a common finding in clients with hyperthyroidism due to increased metabolic activity. Hyperthyroidism leads to an overactive thyroid gland, which results in an increased metabolic rate and often leads to weight loss despite a normal or increased appetite. Cold intolerance (Choice B) is more commonly associated with hypothyroidism, where the body's processes slow down. Bradycardia (Choice C) is a slow heart rate, which is not typically seen in hyperthyroidism; rather, tachycardia or an increased heart rate is more common. Dry skin (Choice D) is also not a typical finding in hyperthyroidism, as the skin is more likely to be warm and moist due to increased metabolic activity.
