1. What is a key intervention for a patient with diabetic ketoacidosis (DKA)?
- A. Administering insulin
- B. Administering IV fluids
- C. Administering oral glucose
- D. Administering oral fluids
Correct answer: A
Rationale: Administering insulin is a crucial intervention for a patient with diabetic ketoacidosis (DKA) because it helps in managing hyperglycemia and ketosis by promoting the uptake of glucose by cells and inhibiting the production of ketones. IV fluids are necessary to correct dehydration and electrolyte imbalances commonly seen in DKA but are not the primary treatment for the condition. Administering oral glucose would exacerbate hyperglycemia in a patient with DKA, while administering oral fluids alone would not effectively address the underlying metabolic disturbances seen in DKA.
2. A client is undergoing hemodialysis. The client’s blood pressure at the beginning of the procedure was 136/88 mm Hg, and now it is 110/54 mm Hg. What actions should the nurse perform to maintain blood pressure? (Select all that apply.)
- A. Adjust the rate of extracorporeal blood flow.
- B. Place the client in the Trendelenburg position.
- C. Administer a 250-mL bolus of normal saline.
- D. All of the above
Correct answer: D
Rationale: During hemodialysis, a drop in blood pressure can occur due to fluid removal. To maintain blood pressure, the nurse should consider adjusting the rate of extracorporeal blood flow to optimize fluid removal without causing hypotension. Placing the client in the Trendelenburg position can help improve venous return and cardiac output. Administering a bolus of normal saline can help increase intravascular volume and support blood pressure. Therefore, all the actions listed in choices A, B, and C are appropriate measures to maintain blood pressure during hemodialysis. Choice D, 'All of the above,' is the correct answer as it encompasses all the relevant actions to address the dropping blood pressure effectively. Choices A, B, and C, when implemented together, can help manage hypotension during hemodialysis.
3. A client's urinalysis results show a urine osmolality of 1200 mOsm/L. What action should the nurse take?
- A. Encourage the client to drink more fluids.
- B. Contact the provider and recommend a low-sodium diet.
- C. Prepare to administer an intravenous diuretic.
- D. Obtain a suction device and implement seizure precautions.
Correct answer: A
Rationale: The correct action for the nurse to take when the client has a urine osmolality of 1200 mOsm/L, indicating dehydration, is to encourage the client to drink more fluids. Dehydration can lead to elevated urine osmolality, and increasing fluid intake can help rehydrate the client. A low-sodium diet is not the priority in this scenario as it would not directly address the dehydration indicated by the high urine osmolality. Administering an intravenous diuretic would further concentrate the urine, exacerbating the dehydration. Obtaining a suction device and implementing seizure precautions are not indicated based on the client's urine osmolality results and would not address the underlying issue of dehydration.
4. A client with chronic heart failure is being taught by a nurse about the importance of daily weights. Which of the following instructions should the nurse include?
- A. Weigh yourself at the same time every day.
- B. Use the same scale for weighing each time.
- C. Record your weight in a journal or log.
- D. Report any weight gain of more than 2 to 3 pounds in a day.
Correct answer: D
Rationale: The correct instruction for a client with chronic heart failure is to report any weight gain of more than 2 to 3 pounds in a day. This weight gain may indicate fluid retention, which is a critical sign of worsening heart failure. Weighing at the same time every day and using the same scale for consistency are good practices, but the crucial action is to promptly report significant weight gain, as stated in option D. Recording the weight in a journal or log can be helpful for tracking trends, but immediate reporting of weight gain is essential for timely intervention in heart failure management. Therefore, option D is the most appropriate instruction for this client.
5. The provider has ordered Kayexalate and sorbitol to be administered to a patient. The nurse caring for this patient would expect which serum electrolyte values prior to administration of this therapy?
- A. Sodium 125 mEq/L and potassium 2.5 mEq/L
- B. Sodium 150 mEq/L and potassium 3.6 mEq/L
- C. Sodium 135 mEq/L and potassium 6.9 mEq/L
- D. Sodium 148 mEq/L and potassium 5.5 mEq/L
Correct answer: C
Rationale: Severe hyperkalemia, with a potassium level of 6.9 mEq/L, requires aggressive treatment with Kayexalate and sorbitol to increase the body’s excretion of potassium. The normal range for serum potassium is 3.5 to 5.5 mEq/L, so patients with the other potassium levels would not be treated aggressively or would need potassium supplementation. Therefore, option C (Sodium 135 mEq/L and potassium 6.9 mEq/L) is the correct choice as it indicates severe hyperkalemia warranting the administration of Kayexalate and sorbitol. Options A, B, and D have either potassium levels within normal limits, which would not necessitate this aggressive treatment, or potassium levels that are lower than what would typically prompt the need for Kayexalate and sorbitol.
