1. A client receives a prescription for 1 liter of lactated Ringer's intravenously to be infused over 6 hours. How many mL/hr should the nurse program the infusion pump to deliver? (Enter numerical value only. If rounding is needed, round to the nearest whole number.)
- A. 167 mL/hr
- B. 200 mL/hr
- C. 83 mL/hr
- D. 111 mL/hr
Correct answer: A
Rationale: The correct infusion rate is 167 mL/hr. This is calculated by dividing the total volume (1000 mL) by the total time (6 hours), resulting in 166.67 mL/hr, which should be rounded to the nearest whole number as 167 mL/hr. This calculation ensures a steady infusion rate over the specified time frame. Choices B, C, and D are incorrect as they do not accurately reflect the correct calculation based on the volume and time provided in the prescription.
2. A client with diabetes mellitus who is taking NPH insulin (Humulin N) in the evening is most likely to become hypoglycemic shortly after midnight because this insulin peaks in 6 to 8 hours. What intervention should the nurse recommend to help prevent hypoglycemia while the client is sleeping?
- A. Eat a bedtime snack.
- B. Avoid physical activity.
- C. Take half the usual dose of insulin.
- D. Discontinue insulin until the next meal.
Correct answer: A
Rationale: Eating a bedtime snack is the most appropriate intervention to prevent hypoglycemia during the night when NPH insulin peaks. This snack helps maintain blood glucose levels and counteracts the risk of hypoglycemia. Avoiding physical activity is not recommended as it can further lower blood sugar levels. Taking half the usual dose of insulin can lead to inadequate control of blood sugar levels. Discontinuing insulin until the next meal can result in uncontrolled hyperglycemia, especially during the peak action of NPH insulin.
3. The client with chronic renal failure is being taught about fluid restrictions by the nurse. Which statement by the client indicates a need for further teaching?
- A. I can drink as much water as I want, as long as I limit my salt intake.
- B. I should limit my fluid intake to prevent fluid overload.
- C. I can skip dialysis sessions if I feel tired.
- D. I can eat whatever I want, as long as I take my medications.
Correct answer: C
Rationale: Choice C is the correct answer because clients with chronic renal failure should not skip dialysis sessions. Skipping dialysis can lead to serious complications and worsen the client's condition. It is crucial for clients to understand the importance of adhering to their dialysis schedule for optimal management of chronic renal failure. Choices A, B, and D are incorrect because they demonstrate understanding of fluid restrictions, the need to limit fluid intake to prevent overload, and the importance of medication compliance, respectively. These statements show appropriate knowledge and do not indicate a need for further teaching.
4. To evaluate the positive effect of furosemide (Lasix) 40 mg/day in a client with chronic kidney disease (CKD), what is the best action for the nurse to take?
- A. Obtain daily weights of the client.
- B. Auscultate heart and breath sounds.
- C. Palpate the client’s abdomen.
- D. Assess the client’s diet history.
Correct answer: A
Rationale: The correct answer is A. Furosemide (Lasix) is a loop diuretic used to manage fluid overload and hypertension in clients with CKD. Monitoring daily weights is crucial as weight changes reflect fluid status. Each kilogram of weight change approximately corresponds to 1 liter of fluid retention or loss, making it essential for evaluating the medication's effectiveness. Auscultating heart and breath sounds is more relevant for heart failure cases with fluid retention, not specifically for assessing the effect of furosemide in CKD. Palpating the abdomen is not a direct indicator of furosemide's effectiveness; instead, assessing for edema would be appropriate. While assessing the client's diet history is important to monitor electrolyte balance due to potassium loss with furosemide, it does not directly evaluate the medication's efficacy.
5. To help minimize the risk of postoperative respiratory complications after a hypophysectomy, during preoperative teaching, the nurse should instruct the client how to:
- A. Use incentive spirometry.
- B. Turn in bed.
- C. Take deep breaths.
- D. Cough.
Correct answer: C
Rationale: The correct answer is to instruct the client on how to take deep breaths. Deep breathing exercises are essential in preventing postoperative respiratory complications like atelectasis by promoting lung expansion. Using incentive spirometry is a more specific and advanced method of promoting deep breathing and lung expansion, making it a better choice than just turning in bed. While turning in bed may help with overall comfort and positioning, it is not as directly related to respiratory complications as deep breathing exercises. Coughing, although important for clearing secretions, is not as effective in preventing atelectasis as deep breathing exercises.
