1. 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.
2. When caring for a child diagnosed with bronchiolitis, what is the priority nursing intervention?
- A. Administering bronchodilators
- B. Providing respiratory therapy
- C. Monitoring oxygen saturation
- D. Encouraging fluid intake
Correct answer: B
Rationale: The priority nursing intervention for a child with bronchiolitis is providing respiratory therapy. This intervention aims to maintain airway patency, optimize oxygenation, and support effective breathing. Administering bronchodilators, though important, may not be the initial priority as respiratory therapy takes precedence in ensuring adequate oxygenation and ventilation. Monitoring oxygen saturation is crucial but is usually part of the ongoing assessment following the initiation of respiratory therapy. Encouraging fluid intake is essential for hydration but is not the priority intervention when addressing the respiratory distress associated with bronchiolitis.
3. The nurse is having difficulty reading the healthcare provider's written order that was written right before the shift change. What action should be taken?
- A. Leave the order for the oncoming staff to follow up
- B. Contact the charge nurse for an interpretation
- C. Ask the pharmacy for assistance in interpretation
- D. Call the provider for clarification
Correct answer: D
Rationale: The nurse should call the provider for clarification. In situations where there is difficulty reading an order, it is crucial to directly contact the healthcare provider to ensure the correct order is understood and followed. Leaving the order for the oncoming staff (Choice A) may lead to misunderstandings and errors. Contacting the charge nurse (Choice B) may cause delays as they may also need to contact the provider. Asking the pharmacy (Choice C) is not the most direct and immediate action in this scenario, as the provider is the one who can provide immediate clarification.
4. Mark, 9 months old, is given oral rehydration solution because of diarrhea with some dehydration. In your follow-up visit, you observed that Mark's eyes become puffy. Which one of the following would you advise Mark's mother?
- A. continue giving ORS but more slowly
- B. show mother how much solution to give
- C. stop ORS and give plain water or milk
- D. reassess patient to determine how much ORS to give
Correct answer: A
Rationale: In this scenario, observing puffy eyes in a child being treated with oral rehydration solution may indicate fluid overload. Continuing to give ORS but more slowly is the correct course of action as it helps manage hydration without overloading fluids. Choice B is not the best option in this situation as the issue is not about the quantity of the solution, but the rate of administration. Choice C is incorrect because plain water or milk is not a suitable alternative for rehydration in cases of dehydration. Choice D is also incorrect as reassessing the patient does not directly address the issue of puffy eyes, which suggests a need to adjust the administration of ORS.
5. A client is receiving total parenteral nutrition (TPN). The nurse should monitor the client for which complication?
- A. Hypoglycemia
- B. Hyperglycemia
- C. Hypertension
- D. Hyperkalemia
Correct answer: B
Rationale: Hyperglycemia is the correct complication to monitor for in a client receiving total parenteral nutrition (TPN) due to the high glucose content of the solution. TPN solutions are rich in glucose, so monitoring blood glucose levels is crucial to prevent hyperglycemia. Hypoglycemia (Choice A) is less common with TPN due to the high glucose content, making hyperglycemia a more significant concern. Hypertension (Choice C) and hyperkalemia (Choice D) are not typically associated with TPN administration, making them incorrect choices in this scenario.
