Correct Answer: B

Rationale: For a client at risk of impaired skin integrity due to decreased tissue perfusion, improving mobility is crucial to enhance tissue perfusion and prevent skin breakdown. Range of motion exercises are beneficial to increase circulation and prevent complications. Massaging reddened areas may further damage fragile skin. Administering antithrombotics may be necessary for specific conditions but does not directly address tissue perfusion. Feeding a high-carbohydrate diet does not directly improve tissue perfusion in this context.

Correct Answer: D

Rationale: A serum creatinine level may be warranted in conditions that can affect renal function or cause muscle breakdown. Rhabdomyolysis, characterized by muscle injury and breakdown, can lead to elevated creatinine levels due to the release of creatinine from muscles. Digitalis toxicity can impair renal function, leading to a need for monitoring creatinine levels. Glomerulonephritis, an inflammatory condition affecting the kidney's filtering units, can also impact renal function and require assessment of creatinine levels. Therefore, all the provided conditions may warrant a serum creatinine level to assess renal function and muscle breakdown.

Correct Answer: B

Rationale: The correct answer is, 'I will probably see a little blood when I urinate.' During a cystoscopy, a scope is inserted into the client's bladder to inspect structures or remove objects like stones. This procedure is usually performed under local or general anesthesia. It is common for clients to experience a small amount of blood in their urine (hematuria) or have pink-colored urine after the procedure. The other choices are incorrect because drinking a lot of fluid before the test, staying in the hospital for 3 days, and assuming no pain will be experienced are not accurate statements related to a cystoscopy procedure.

Correct Answer: D

Rationale: The parathyroid glands regulate calcium, vitamin D, and phosphorus in the body. Hyperparathyroidism leads to excessive production of parathyroid hormone, causing the release of calcium from bones into the bloodstream, resulting in elevated blood calcium levels, known as hypercalcemia. This puts individuals at risk of developing complications such as kidney stones, bone pain, osteoporosis, and neuropsychiatric symptoms. The other options, hyponatremia, hypocalcemia, and hypermagnesemia, are not directly associated with hyperparathyroidism. Hyponatremia is low sodium levels in the blood, hypocalcemia is low calcium levels, and hypermagnesemia is high magnesium levels, which are not typically seen in hyperparathyroidism.

Correct Answer: C

Rationale: Type 1 diabetes is an autoimmune condition where the immune system attacks and destroys the beta cells in the pancreas, leading to a lack of insulin production. Insulin is essential for regulating blood glucose levels and enabling cells to use glucose for energy. Understanding that type 1 diabetes results from the destruction of beta cells helps patients comprehend the need for insulin replacement therapy. Choices A and B are incorrect as type 1 diabetes is not primarily caused by diet or exercise habits. Choice D is incorrect because type 1 diabetes is not about the body's cells rejecting insulin but rather the lack of insulin production due to beta cell destruction.
