1. A client with diabetes mellitus is admitted with a blood glucose level of 640 mg/dl and is unresponsive. Which intervention should the nurse implement first?
- A. Administer 50% dextrose IV push
- B. Administer IV fluids as prescribed
- C. Check the client's blood glucose level
- D. Prepare the client for immediate dialysis
Correct answer: B
Rationale: Administering IV fluids as prescribed is the priority intervention in a client with a blood glucose level of 640 mg/dl and unresponsiveness. Severe hyperglycemia can lead to dehydration and electrolyte imbalances, and administering IV fluids can help manage hyperglycemia and prevent further complications. Administering dextrose IV push (Choice A) can exacerbate hyperglycemia in this scenario. Checking the client's blood glucose level (Choice C) is important but not the immediate priority when the client is unresponsive. Immediate dialysis (Choice D) is not indicated as the first intervention for hyperglycemia.
2. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which laboratory value is most concerning?
- A. Serum glucose of 300 mg/dL
- B. Blood pressure of 140/90 mmHg
- C. Serum osmolarity of 320 mOsm/kg
- D. Serum pH of 7.30
Correct answer: C
Rationale: In a client with hyperglycemic hyperosmolar syndrome (HHS), a serum osmolarity of 320 mOsm/kg is the most concerning laboratory value. This high osmolarity indicates severe dehydration, which can lead to serious complications. Elevated serum glucose levels (choice A) are expected in HHS but do not directly reflect dehydration. Blood pressure (choice B) and serum pH (choice D) are important parameters to monitor but are not the most concerning values in HHS compared to serum osmolarity.
3. The nurse is caring for a client with diabetic ketoacidosis (DKA). Which laboratory value requires immediate intervention?
- A. Serum glucose of 300 mg/dL
- B. Serum potassium of 4.5 mEq/L
- C. Serum bicarbonate of 15 mEq/L
- D. Serum pH of 7.28
Correct answer: D
Rationale: A serum pH of 7.28 indicates metabolic acidosis in a client with diabetic ketoacidosis (DKA), requiring immediate intervention. In DKA, the body produces excess ketones, leading to acidosis. Monitoring and correcting the pH level is crucial in managing DKA. Serum glucose levels may be high in DKA, but the immediate concern is correcting the acidosis to prevent complications. Serum potassium and bicarbonate levels are also important but not as immediately critical as correcting the acidosis in DKA.
4. The mother of a one-month-old boy born at home brings the infant to his first well-baby visit. She mentions that he was born two weeks after his due date and is a 'good, quiet baby' who almost never cries. To assess for hypothyroidism, what question is most important for the nurse to ask the mother?
- A. Has your son had any immunizations yet?
- B. Is your son sleepy and difficult to feed?
- C. Are you breastfeeding or bottle feeding your son?
- D. Were any relatives born with birth defects?
Correct answer: B
Rationale: The correct answer is B. Sleepiness and difficulty feeding are key signs of congenital hypothyroidism, which requires early diagnosis and treatment. Asking about immunizations (choice A) is important but not directly related to assessing hypothyroidism. The feeding method (choice C) is relevant for overall health but not specific to hypothyroidism. Inquiring about relatives with birth defects (choice D) is not the most crucial question to assess hypothyroidism in this scenario.
5. A client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which laboratory value should be reported to the healthcare provider before the procedure?
- A. Serum creatinine of 2.5 mg/dL
- B. Serum potassium of 6.5 mEq/L
- C. Serum calcium of 8 mg/dL
- D. Serum bicarbonate of 24 mEq/L
Correct answer: B
Rationale: The correct answer is B. A serum potassium level of 6.5 mEq/L is dangerously high and should be reported before hemodialysis to prevent cardiac complications. High potassium levels can lead to life-threatening arrhythmias. Serum creatinine (Choice A) is elevated in renal dysfunction but not the most critical value to report before hemodialysis. Serum calcium (Choice C) and serum bicarbonate (Choice D) levels are within normal limits and are not immediate concerns before hemodialysis.
