1. A client is receiving lidocaine IV at 3 mg/minute. The pharmacy dispenses a 500 ml IV solution of normal saline (NS) with 2 grams of lidocaine. The nurse should regulate the infusion pump to deliver how many ml/hour?
- A. 18
- B. 27
- C. 36
- D. 45
Correct answer: D
Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg). Then, use the formula: (Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.
2. The nurse provides discharge teaching to a client who was recently diagnosed with diabetes mellitus (DM). After receiving the instructions, the client expresses understanding about when, how, and why to take his prescribed medications at home. Which intervention is most important for the nurse to implement?
- A. Review the purpose of medications prescribed for the client to take home with him
- B. Provide the client with a printed list of medications and a schedule for administration
- C. Send a list of medications taken while hospitalized to the client’s healthcare provider
- D. Offer to consult with the pharmacist about resources for reduced-price medications
Correct answer: B
Rationale: Providing the client with a printed list of medications and a schedule for administration is crucial to ensure adherence and understanding of the medication regimen at home. This intervention helps the client follow the prescribed treatment plan accurately. Choice A is not as essential since the client already understands when, how, and why to take the medications. Choice C is not a priority at this point as the client needs information for home medication management. Choice D, while helpful, is not the most important intervention compared to providing a clear list and schedule for medication administration.
3. A male client with schizophrenia is jerking his neck and smacking his lips. Which finding indicates to the nurse that he is experiencing an irreversible side effect of antipsychotic agents?
- A. Cramping muscular pain
- B. Worming movements of the tongue
- C. Decreased tendon reflexes
- D. Dry oral mucous membranes
Correct answer: B
Rationale: The correct answer is B: Worming movements of the tongue. Worming movements of the tongue, known as tardive dyskinesia, are an irreversible side effect of antipsychotic medications. Tardive dyskinesia is characterized by involuntary, repetitive movements of the tongue, lips, face, trunk, and extremities. Cramping muscular pain (Choice A) is more indicative of dystonia, an extrapyramidal side effect that can be treated effectively with antiparkinsonian medications. Decreased tendon reflexes (Choice C) are not typically associated with irreversible side effects of antipsychotic agents. Dry oral mucous membranes (Choice D) are not specific to irreversible side effects of antipsychotic medications.
4. What actions should the nurse take regarding an older adult male who had an abdominal cholecystectomy and has become increasingly confused and disoriented over the past 24 hours, found wandering into another client’s room and returned to his own room by the unlicensed assistive personnel (UAP)? (Select all that apply)
- A. Apply soft upper limb restraints and raise all four bed rails
- B. Report mental status change to the healthcare provider
- C. Assess the client’s breath sounds and oxygen saturation
- D. Assign the UAP to re-assess the client’s risk for falls
Correct answer: B
Rationale: In this situation, the appropriate action for the nurse to take is to report the mental status change to the healthcare provider. Confusion and disorientation post-surgery can be indicative of various factors, such as electrolyte imbalances or respiratory issues, necessitating comprehensive assessment by the healthcare team. Applying restraints and raising bed rails may not address the underlying cause of the confusion, and assigning the UAP to reassess the client's risk for falls does not directly address the cognitive changes observed.
5. The nurse is admitting a client from the post-anesthesia unit to the postoperative surgical care unit. Which intervention should the nurse implement first?
- A. Advance to clear liquids as tolerated
- B. Straight catheterization if unable to void
- C. Administer Cefazolin 1 gram IVPQ q6 hours
- D. Obtain a complete blood cell count (CBC) in the morning
Correct answer: B
Rationale: The correct answer is to perform straight catheterization if the client is unable to void. This action is essential to prevent urinary retention and its potential complications following anesthesia. Option A, advancing to clear liquids, is not the priority upon admission as the focus should be on urinary function first. Option C involves administering an antibiotic, which is important but not the immediate priority. Option D, obtaining a CBC, can be done later and is not as crucial as ensuring proper urinary function postoperatively.
