1. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which clinical finding is most concerning?
- A. Serum glucose of 500 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: A serum osmolarity of 320 mOsm/kg is the most concerning finding in a client with hyperglycemic hyperosmolar syndrome (HHS). This level of osmolarity indicates severe dehydration and hyperosmolarity, putting the client at risk of complications like organ failure. Immediate intervention is crucial to address the dehydration and restore fluid balance. The other options, while important in the overall assessment of a client with HHS, do not directly indicate the severity of dehydration and hyperosmolarity seen with a high serum osmolarity level.
2. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which clinical finding requires immediate intervention?
- A. Serum glucose of 300 mg/dL
- B. Serum potassium of 5.5 mEq/L
- C. Serum bicarbonate of 18 mEq/L
- D. Positive urine ketones
Correct answer: C
Rationale: A serum bicarbonate level of 18 mEq/L indicates metabolic acidosis in a client with DKA, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis, which is reflected by a low serum bicarbonate level. Correcting the low serum bicarbonate is crucial to normalize the metabolic acidosis and improve the client's condition. While elevated serum glucose (choice A) and urine ketones (choice D) are characteristic of DKA, addressing the metabolic acidosis takes precedence. Serum potassium (choice B) levels may also need monitoring and management, but correcting the acidosis is the priority to prevent complications like cardiovascular collapse.
3. During the initial newborn assessment, the nurse finds that a newborn's heart rate is irregular. Which intervention should the nurse implement?
- A. Notify the pediatrician immediately.
- B. Teach the parents about congenital heart defects.
- C. Document the finding in the infant's record.
- D. Apply oxygen via nasal cannula at 3 L/min.
Correct answer: C
Rationale: The correct intervention when a nurse finds an irregular heart rate in a newborn is to document the finding in the infant's record. An irregular heart rate is a common occurrence in newborns and does not necessarily require immediate medical intervention. Notifying the pediatrician immediately is unnecessary unless there are other concerning symptoms. Teaching the parents about congenital heart defects is not the priority in this situation. Applying oxygen via nasal cannula at 3 L/min is not indicated for an irregular heart rate without further assessment or medical indication.
4. The nurse is assessing a client with right-sided heart failure. Which finding requires immediate intervention?
- A. Jugular venous distention
- B. Peripheral edema
- C. Crackles in the lungs
- D. Elevated liver enzymes
Correct answer: C
Rationale: In a client with right-sided heart failure, crackles in the lungs are the most concerning finding as they indicate pulmonary congestion, which requires immediate intervention. Crackles suggest fluid accumulation in the lungs, leading to impaired gas exchange and potential respiratory distress. Jugular venous distention (Choice A) and peripheral edema (Choice B) are common findings in right-sided heart failure but do not indicate acute deterioration requiring immediate intervention. Elevated liver enzymes (Choice D) may be seen in chronic heart failure but do not warrant immediate action compared to the urgent need to address pulmonary congestion indicated by crackles in the lungs.
5. A client with type 1 diabetes is admitted with hypoglycemia. Which intervention should the nurse implement first?
- A. Administer 50% dextrose IV push
- B. Administer 15 grams of oral glucose
- C. Recheck the blood glucose level in 15 minutes
- D. Administer a glucagon injection
Correct answer: A
Rationale: Administering 50% dextrose IV push is the first priority in treating hypoglycemia to rapidly increase blood glucose levels. This choice is correct because in severe cases of hypoglycemia, when a client is admitted and unconscious or unable to swallow, intravenous administration of dextrose is crucial to quickly raise blood glucose levels. Option B, administering 15 grams of oral glucose, would be suitable for conscious clients with mild hypoglycemia who can swallow safely. Option C, rechecking blood glucose levels, should follow after immediate intervention to assess the response. Option D, administering a glucagon injection, is more suitable for cases where dextrose is not readily available or when the client does not respond to dextrose administration.
