Nursing Elites

1. The healthcare provider is assessing a client with suspected syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following laboratory findings is most consistent with this condition?

• A. Increased serum sodium
• B. Decreased urine specific gravity
• C. Decreased serum osmolality
• D. Increased serum potassium

Correct answer: C

Rationale: The correct answer is C: Decreased serum osmolality. Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by the excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. The dilution of sodium results in decreased serum osmolality. Option A is incorrect because SIADH causes hyponatremia, resulting in decreased serum sodium levels. Option B is incorrect because SIADH leads to concentrated urine with increased urine specific gravity. Option D is incorrect as SIADH does not typically affect serum potassium levels.

2. For a diabetic male client with a foot ulcer, the physician orders bed rest, a wet-to-dry dressing change every shift, and blood glucose monitoring before meals and bedtime. Why are wet-to-dry dressings used for this client?

• A. They contain exudate and provide a moist wound environment.
• B. They protect the wound from mechanical trauma and promote healing.
• C. They debride the wound and promote healing by secondary intention.
• D. They prevent the entrance of microorganisms and minimize wound discomfort.

Correct answer: C

Rationale: Wet-to-dry dressings are utilized in this case to debride the wound by removing dead tissue and promoting healing by secondary intention. Choice A is incorrect as wet-to-dry dressings do not provide a moist wound environment; instead, they promote drying to aid in debridement. Choice B is incorrect because their primary purpose is not to protect the wound but to remove dead tissue. Choice D is incorrect as the main function of wet-to-dry dressings is not to prevent the entrance of microorganisms or minimize wound discomfort.

3. A nurse caring for a group of clients reviews the electrolyte laboratory results and notes a potassium level of 5.5 mEq/L on one client's laboratory report. The nurse understands that which client is at highest risk for the development of a potassium value at this level?

• A. The client with colitis
• B. The client with Cushing's syndrome
• C. The client who has been overusing laxatives
• D. The client who has sustained a traumatic burn

Correct answer: D

Rationale: Clients who have sustained traumatic burns are at a higher risk of developing hyperkalemia due to cell lysis. When cells are damaged in a traumatic burn, potassium can leak out from the intracellular space into the bloodstream, leading to elevated serum potassium levels. Colitis, Cushing's syndrome, and overuse of laxatives are not typically associated with the same degree of cell damage or potassium shifts seen in traumatic burns, making them less likely to result in such high potassium levels.

4. Albert, a 35-year-old insulin-dependent diabetic, is admitted to the hospital with a diagnosis of pneumonia. He has been febrile since admission. His daily insulin requirement is 24 units of NPH. Every morning Albert is given NPH insulin at 0730. Meals are served at 0830, 1230, and 1830. The nurse expects that the NPH insulin will reach its maximum effect (peak) between the hours of:

• A. 1130 and 1330.
• B. 1330 and 1930.
• C. 1530 and 2130.
• D. 1730 and 2330.

Correct answer: C

Rationale: NPH insulin typically peaks 4-12 hours after administration, so a peak between 1530 and 2130 would be expected. Choice A (1130 and 1330) is too early for the peak effect of NPH insulin. Choice B (1330 and 1930) falls within the possible peak period but is not as accurate as choice C. Choice D (1730 and 2330) is too late for the peak effect of NPH insulin based on the typical peak timing.

5. A client with type 2 diabetes mellitus is being discharged after receiving initial treatment. What should the nurse emphasize as a crucial instruction?

• A. Take insulin as prescribed, even if you are not eating.
• B. Avoid all forms of physical exercise to prevent hypoglycemia.
• C. Monitor blood glucose levels regularly and report any changes.
• D. Stop taking oral antidiabetic medication if your blood glucose levels are normal.

Correct answer: C

Rationale: Monitoring blood glucose levels regularly is a critical aspect of managing type 2 diabetes mellitus. This allows the individual to track their blood sugar levels, understand the effectiveness of the treatment plan, and detect any fluctuations promptly. Option A is incorrect because insulin should be taken based on a prescribed schedule that correlates with meals to prevent hypoglycemia or hyperglycemia. Option B is incorrect as physical exercise is beneficial for managing diabetes but should be done cautiously with adjustments in insulin or food intake. Option D is incorrect because discontinuing oral antidiabetic medications without healthcare provider guidance can lead to uncontrolled blood glucose levels.
