1. A client has a prescription for 5 units of regular insulin and 10 units of NPH insulin to mix together and administer subcutaneously. Determine the correct order of steps for this procedure.
- A. Inject 5 units of air into the bottle of regular insulin
- B. Withdraw the correct dose of NPH insulin from the bottle
- C. Inject 10 units of air into the bottle of NPH insulin
- D. Withdraw the correct dose of regular insulin from the bottle
Correct answer: B
Rationale: The correct order of steps for this procedure is to first inject air into the NPH insulin bottle to prevent vacuum formation. After injecting air into the NPH insulin, the next step is to withdraw the correct dose of regular insulin from its bottle. This sequence ensures that the regular insulin is drawn after the NPH insulin, preventing contamination and ensuring accurate dosing. Therefore, choice B is correct. Choices A, C, and D are incorrect because air should be injected into the NPH insulin first, not the regular insulin, and the doses should be withdrawn in the appropriate order to maintain the integrity and potency of each insulin type.
2. The LPN/LVN mixes 50 mg of Nipride in 250 ml of D5W and plans to administer the solution at a rate of 5 mcg/kg/min to a client weighing 182 pounds. Using a drip factor of 60 gtt/ml, how many drops per minute should the client receive?
- A. 31 gtt/min.
- B. 62 gtt/min.
- C. 93 gtt/min.
- D. 124 gtt/min.
Correct answer: D
Rationale: To calculate the drops per minute for the client, first, convert the weight from pounds to kilograms by dividing 182 by 2.2, which equals 82.72 kg. Then, calculate the dose in mcg/min by multiplying the weight in kg by the rate (82.72 kg * 5 mcg/kg/min = 413.6 mcg/min). Next, convert 50 mg to mcg (50 mg * 1000 = 50,000 mcg). Divide the total mcg (50,000 mcg) by the dose per minute (413.6 mcg/min) to get approximately 121 gtt/min. However, since the drip factor is 60 gtt/ml, the correct answer is 124 gtt/min, ensuring the accurate administration rate of the medication. Therefore, choice 'D' is the correct answer. Choices 'A', 'B', and 'C' are incorrect as they do not accurately reflect the calculated drops per minute based on the given information.
3. A nurse is caring for a client who is postoperative and has signs of hemorrhagic shock. When the nurse notifies the surgeon, he directs her to continue measuring the client's vital signs every 15 minutes and call him back in 1 hour. From a legal perspective, which of the following actions should the nurse take next?
- A. Document the provider's directive in the medical record
- B. Notify the nursing manager
- C. Consult the facility's risk manager
- D. Complete an incident report
Correct answer: B
Rationale: In this scenario, the nurse is facing a critical situation with a client showing signs of hemorrhagic shock. The surgeon's directive of waiting for an hour without providing immediate intervention poses a risk to the client's well-being. The nurse should prioritize the client's safety and advocate for timely and appropriate care. Notifying the nursing manager is the correct action as it activates the chain of command to ensure that the client receives the necessary care promptly. Documenting the provider's directive, consulting the risk manager, or completing an incident report are not the immediate actions needed to address the client's deteriorating condition and ensure patient safety.
4. The nurse manager has been using a decentralized block scheduling plan to staff the nursing unit. However, staff have asked for many changes and exceptions to the schedule over the past few months. The manager considers self-scheduling knowing that this method will
- A. Improve the quality of care
- B. Decrease staff turnover
- C. Minimize the amount of overtime payouts
- D. Improve team morale
Correct answer: D
Rationale: The correct answer is D: 'Improve team morale.' Self-scheduling allows staff more control over their work hours, which can lead to increased job satisfaction, autonomy, and a sense of ownership over their schedules. This, in turn, fosters a positive work environment, enhances collaboration among team members, and boosts morale. Choices A, B, and C are incorrect because while self-scheduling may indirectly contribute to improved quality of care, decreased staff turnover, and minimized overtime payouts, the primary benefit in this context is the positive impact on team morale.
5. A client has been admitted to the hospital with severe diarrhea. The nurse should monitor the client for which complication?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Hyperkalemia
- D. Hypercalcemia
Correct answer: A
Rationale: Severe diarrhea can lead to metabolic acidosis due to the loss of bicarbonate. When there is excessive loss of bicarbonate through diarrhea, the pH of the blood decreases, leading to metabolic acidosis. Metabolic alkalosis (Choice B) is not typically associated with severe diarrhea as it involves elevated pH and bicarbonate levels. Hyperkalemia (Choice C) is less likely with severe diarrhea as potassium is often lost along with fluids. Hypercalcemia (Choice D) is not a common complication of severe diarrhea; instead, hypocalcemia may occur due to malabsorption of calcium.
