1. An older client is receiving an IV of 5% dextrose in 0.45% normal saline at 75 mL/hour. Which assessment finding indicates to the nurse that the client is developing a complication from this therapy?
- A. Capillary refill takes > 3 seconds.
- B. Episodes of vertigo and loss of balance.
- C. Average daily output of 1200 ml.
- D. Pulse rate of 110 beats/minute and dyspnea upon exertion.
Correct answer: D
Rationale: The correct answer is D. Tachycardia and dyspnea are signs of fluid overload, which is a potential complication of IV fluid therapy. Choices A, B, and C are not directly related to fluid overload and are not typical signs of complications associated with the IV fluid therapy being administered.
2. A client with asthma is prescribed a metered-dose inhaler (MDI) with albuterol. Which instruction is essential for the nurse to provide?
- A. Use the inhaler only before bedtime
- B. Shake the inhaler well before use
- C. Exhale fully before inhaling the medication
- D. Take two puffs every hour
Correct answer: B
Rationale: The correct answer is to 'Shake the inhaler well before use.' This instruction is crucial as shaking the inhaler ensures the proper mixing of the medication, which is essential for its effective delivery. Option A is incorrect because using the inhaler only before bedtime may not provide adequate relief during the day. Option C is incorrect as exhaling fully is a good practice but not the most essential instruction. Option D is incorrect as taking two puffs every hour may exceed the recommended dosage and lead to adverse effects.
3. Since children with attention deficit hyperactivity disorder (ADHD) take medication for long periods of time, side effects must be considered. How often should children be assessed for side effects of the drug therapy?
- A. Every 2 months
- B. Every 4 months
- C. Every 6 months
- D. Every 8 months
Correct answer: C
Rationale: Children with ADHD who are on long-term medication therapy should be assessed for side effects every 6 months. This timeframe allows healthcare providers to monitor the effects of the medication and make any necessary adjustments. Checking every 2 months (Choice A) may be too frequent and not practical for routine monitoring, while checking every 4 or 8 months (Choices B and D) may lead to missing potential side effects or delays in addressing them.
4. A client is receiving a secondary infusion of erythromycin 1 gram in 100 mL dextrose 5% in water (D5W) to be infused in 45 minutes. How many mL/hour should the nurse program the infusion pump?
- A. 100 mL/hour.
- B. 125 mL/hour.
- C. 133 mL/hour.
- D. 150 mL/hour.
Correct answer: C
Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.
5. A client with peptic ulcer disease is prescribed sucralfate. What is the mechanism of action of this medication?
- A. Neutralizes stomach acid
- B. Decreases gastric acid secretion
- C. Covers the ulcer site and protects it from acid
- D. Improves gastric motility
Correct answer: C
Rationale: The correct answer is C: Covers the ulcer site and protects it from acid. Sucralfate works by forming a protective barrier over ulcers, shielding them from stomach acid and promoting healing. Choice A, neutralizing stomach acid, is incorrect as sucralfate does not neutralize acid but acts as a physical barrier. Choice B, decreasing gastric acid secretion, is not the mechanism of action of sucralfate. Choice D, improving gastric motility, is unrelated to sucralfate's action on peptic ulcers.
