1. 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.
2. A client with liver cirrhosis and severe ascites has a serum sodium level of 115 mEq/L and is receiving 3% saline IV. Which assessment finding indicates that the nurse should notify the healthcare provider?
- A. The client's serum sodium level is now 130 mEq/L
- B. The client reports a headache and has a BP of 140/90
- C. The client reports shortness of breath and has an O2 saturation of 92%
- D. The client has crackles in both lung bases and an increased respiratory rate.
Correct answer: D
Rationale: The presence of crackles in both lung bases and an increased respiratory rate indicates fluid overload, which can be exacerbated by hypertonic saline. This condition can worsen the client's respiratory status and lead to further complications. The other options do not directly relate to the fluid overload caused by the hypertonic saline. A serum sodium level of 130 mEq/L is within a normal range for treatment. A headache and a blood pressure of 140/90 are not specific indicators of worsening condition related to hypertonic saline. Shortness of breath and an O2 saturation of 92% could be related to other factors in a client with liver cirrhosis and ascites.
3. The nurse needs to add a medication to a liter of 5% Dextrose in Water (D5W) that is already infusing into a client. At what location should the nurse inject the medication?
- A. Medication port
- B. IV drip chamber
- C. Y-site connector
- D. At the hub of the IV catheter
Correct answer: A
Rationale: The correct answer is the medication port. When adding medication to an already infusing IV solution, it should be done through the medication port to ensure direct delivery into the bloodstream without interrupting the primary IV line. Injecting the medication into the IV drip chamber, Y-site connector, or at the hub of the IV catheter can lead to dilution, inaccurate dosing, or potential blockages in the IV line, which can compromise the effectiveness of the medication and patient safety.
4. An unlicensed assistive personnel (UAP) assigned to obtain client vital signs reports to the charge nurse that a client has a weak pulse with a rate of 44 beats/minute. What action should the charge nurse implement?
- A. Instruct the UAP to count the client's apical pulse rate for sixty seconds.
- B. Determine if the UAP also measured the client's capillary refill time.
- C. Assign a practical nurse (LPN) to determine if an apical-radial pulse deficit is present.
- D. Notify the healthcare provider of the abnormal pulse rate and pulse volume.
Correct answer: C
Rationale: The correct action for the charge nurse to implement in this situation is to assign a practical nurse (LPN) to determine if an apical-radial pulse deficit is present. This helps to confirm the accuracy of the reported weak pulse. In this scenario, it is crucial to involve a licensed nurse to further assess the situation and provide a more comprehensive evaluation. Inaccurate pulse readings can lead to inappropriate interventions or unnecessary alarm. Instructing the UAP to count the apical pulse may not address the accuracy issue. Checking capillary refill time is not directly related to confirming the weak pulse rate. Notifying the healthcare provider immediately may be premature without confirming the accuracy of the pulse reading first.
5. The nurse is preparing a 50 ml dose of 50% dextrose IV for a client with insulin shock. What is the most immediate intervention by the nurse?
- A. Dilute the dextrose in one liter of 0.9% Normal Saline solution.
- B. Mix the dextrose in a 50 ml piggyback for a total volume of 100 ml.
- C. Push the undiluted dextrose slowly through the current IV infusion.
- D. Ask the pharmacist to add the dextrose to a TPN solution.
Correct answer: C
Rationale: The correct immediate intervention by the nurse in this situation is to push the undiluted 50% dextrose slowly through the current IV infusion. This is because in cases of insulin shock, where the client has dangerously low blood sugar levels, administering 50% dextrose directly into the bloodstream helps rapidly increase blood glucose levels. Choice A is incorrect because diluting the dextrose in one liter of normal saline would delay the administration of glucose, which is needed urgently. Choice B is incorrect as mixing the dextrose in a piggyback solution would also delay the administration of the concentrated dextrose. Choice D is incorrect because adding dextrose to a TPN solution is not the immediate intervention needed to address the low blood sugar levels in a client experiencing insulin shock.
