1. When administering diazepam, a benzodiazepine, 10 mg IV push PRN for a client with alcohol withdrawal symptoms, which actions should the nurse implement? (Select all that apply)
- A. Protect the medication from light exposure
- B. Monitor for changes in level of consciousness
- C. Observe for onset of generalized bruising or bleeding
- D. Perform ongoing assessment of respiratory status
Correct answer: D
Rationale: When administering diazepam for a client with alcohol withdrawal symptoms, it is crucial to perform ongoing assessment of respiratory status. Diazepam can lead to respiratory depression, emphasizing the need for continuous monitoring to detect any signs of respiratory distress early. Protecting the medication from light exposure is a general guideline for some drugs but is not a specific concern for diazepam. Observing for bruising or bleeding is not directly associated with the administration of diazepam for alcohol withdrawal symptoms, making choices A and C incorrect.
2. The nurse is preparing an older client for discharge following cataract extraction. Which instruction should be included in the discharge teaching?
- A. Do not read with direct lighting for 6 weeks
- B. Avoid straining during stool passage, bending, or lifting heavy objects
- C. Irrigate conjunctiva with ophthalmic saline after applying antibiotic ointment
- D. Limit exposure to sunlight during the first 2 weeks while the cornea is healing
Correct answer: B
Rationale: The correct instruction to include in the discharge teaching for a client following cataract extraction is to 'Avoid straining during stool passage, bending, or lifting heavy objects.' This is crucial to prevent increased intraocular pressure after surgery, which can be harmful. Reading with direct lighting can strain the eyes but is not the primary concern post-cataract surgery. Irrigating the conjunctiva before applying antibiotic ointment is not a standard practice and may not be necessary. While limiting sunlight exposure is important for eye protection, it is secondary to avoiding activities that can increase intraocular pressure.
3. A client with acute renal failure (ARF) is admitted for uncontrolled type 1 diabetes mellitus and hyperkalemia. The nurse administers an IV dose of regular insulin per sliding scale. Which intervention is the most important for the nurse to include in this client’s plan of care?
- A. Monitor the client’s cardiac activity via telemetry.
- B. Maintain venous access with an infusion of normal saline.
- C. Assess glucose levels via finger stick every 4 to 6 hours.
- D. Evaluate hourly urine output for the return of normal renal function.
Correct answer: A
Rationale: Monitoring cardiac activity is crucial in this scenario because hyperkalemia can lead to serious cardiac dysrhythmias, which can be life-threatening. Regular monitoring of the client’s cardiac activity via telemetry allows for early detection of any potential cardiac complications. Maintaining venous access with a normal saline infusion is important for hydration but does not address the immediate risk of cardiac dysrhythmias posed by hyperkalemia. Assessing glucose levels is essential in diabetes management but is not the priority when dealing with hyperkalemia-induced cardiac risks. Evaluating hourly urine output for the return of normal renal function is important in ARF but is not as urgent as monitoring the client's cardiac activity in the context of hyperkalemia.
4. A male client admitted three days ago with respiratory failure is intubated and receiving 40% oxygen per facemask. Currently, his temperature is 99°F, capillary refill is less than 4 seconds, and respiratory effort is within normal limits. What outcome should the nurse evaluate to measure for successful extubation?
- A. Exhibits adequate tissue perfusion
- B. Remains free of injury
- C. Remains free of infection
- D. Maintains effective breathing pattern
Correct answer: D
Rationale: Successful extubation is primarily measured by the client's ability to maintain an effective breathing pattern. This indicates that the client can adequately oxygenate and ventilate without the need for artificial airway support. Choices A, B, and C are important aspects of patient care but are not the primary outcomes to evaluate for successful extubation. Adequate tissue perfusion, freedom from injury, and prevention of infection are ongoing goals during the client's hospitalization but are not the immediate focus when considering extubation.
5. A client receives a prescription for acetylcysteine (Mucomyst) 1.4 grams per nasogastric tube q4 hours. Acetylcysteine is available as a 10% solution (10 grams/100ml). How many ml of the 10% solution should the nurse administer per dose?
- A. 7
- B. 10
- C. 14
- D. 1.4 grams of acetylcysteine is equivalent to 14 ml of a 10% solution.
Correct answer: D
Rationale: To determine the amount of the 10% acetylcysteine solution to administer, convert the 1.4 grams to milligrams (1.4 grams = 1400 mg). Then, as the 10% solution contains 10 grams (10,000 mg) per 100 ml, it means there are 1000 mg of acetylcysteine in every 10 ml of the solution (10,000 mg / 100 ml = 100 mg/ml). Therefore, to administer 1400 mg (1.4 grams) of acetylcysteine, the nurse should give 14 ml of the 10% solution. Choices A, B, and C are incorrect as they do not accurately convert the amount of acetylcysteine to the corresponding volume of the 10% solution.
