1. The healthcare professional is preparing to administer potassium chloride intravenously to a client with hypokalemia. Which action is most important?
- A. Monitor the client's respiratory rate
- B. Check the client's urine output
- C. Administer the potassium chloride as a rapid IV push
- D. Dilute the potassium chloride in an appropriate IV solution
Correct answer: D
Rationale: The correct answer is to dilute the potassium chloride in an appropriate IV solution. Potassium chloride should never be administered as a rapid IV push as it can lead to severe complications, including cardiac arrhythmias. Diluting the medication and administering it slowly helps reduce the risk of adverse effects. Monitoring the client's respiratory rate (Choice A) and checking urine output (Choice B) are important aspects of patient assessment but not the most crucial when administering potassium chloride. Administering potassium chloride as a rapid IV push (Choice C) is dangerous and can result in serious harm to the client.
2. The client is advised to take dexamethasone (Decadron) with food or milk. What is the physiological basis for this advice?
- A. Inhibits pepsin production
- B. Stimulates hydrochloric acid production
- C. Delays stomach emptying time
- D. Reduces hydrochloric acid production
Correct answer: B
Rationale: The correct answer is B: Stimulates hydrochloric acid production. Dexamethasone can stimulate the production of hydrochloric acid in the stomach, which may lead to irritation of the stomach lining. Taking dexamethasone with food or milk helps to neutralize or buffer the acid, reducing the risk of stomach irritation. Choice A is incorrect because dexamethasone does not inhibit pepsin production. Choice C is incorrect as dexamethasone does not slow stomach emptying time. Choice D is incorrect as dexamethasone does not reduce hydrochloric acid production.
3. The client with a diagnosis of chronic heart failure is receiving discharge teaching. Which statement by the client indicates a need for further teaching?
- A. I will weigh myself every day at the same time.
- B. I will call my doctor if my legs swell more.
- C. I will take my water pill only when I feel short of breath.
- D. I will limit the amount of salt in my diet.
Correct answer: C
Rationale: The correct answer is C. Taking water pills (diuretics) only when feeling short of breath is incorrect. Diuretics should be taken regularly as prescribed to help manage fluid retention in chronic heart failure. This statement indicates a need for further teaching as the client needs to understand the importance of consistent medication adherence. Choices A, B, and D demonstrate good understanding of self-care management in heart failure, including daily weight monitoring, prompt reporting of worsening symptoms to the healthcare provider, and dietary sodium restriction, respectively.
4. The nurse is preparing to administer a medication through a nasogastric (NG) tube. Which action should the LPN/LVN take to ensure proper administration?
- A. Check the placement of the tube by auscultation.
- B. Flush the tube with 30 ml of water before and after medication administration.
- C. Administer the medication with food to prevent nausea.
- D. Dilute the medication with normal saline before administration.
Correct answer: B
Rationale: To ensure proper administration through a nasogastric tube, the LPN/LVN should flush the tube with 30 ml of water before and after medication administration. This action helps ensure the tube is patent, prevents clogging, and helps deliver the medication effectively. Checking the placement of the tube by auscultation (Choice A) is essential but does not directly relate to ensuring proper administration. Administering the medication with food (Choice C) may not always be appropriate for all medications and may not necessarily prevent nausea. Diluting the medication with normal saline (Choice D) is not a standard practice for all medications administered via an NG tube and may alter the medication's effectiveness.
5. The nurse is working on an orthopedic rehabilitation unit that requires lifting and positioning of patients. Which personal injury will the nurse most likely try to prevent?
- A. Arm
- B. Hip
- C. Back
- D. Ankle
Correct answer: C
Rationale: The correct answer is C: Back. Back injuries are common among healthcare workers, especially nurses, due to improper lifting techniques and bending. Working on an orthopedic rehabilitation unit involves frequent lifting and positioning of patients, putting the nurse at risk of back injuries. Preventing back injuries is crucial for maintaining the nurse's health and ability to provide care effectively. Choices A, B, and D are incorrect because while lifting and positioning patients may involve these body parts, back injuries are most likely to occur due to the strain and stress placed on the back during such activities.
