Critical Care Nursing Questions Questions
Question 1 of 5
The most common reasons for initiating dialysis in acute kidney injury include which of the following? (Select all that apply.)
Correct Answer: C
Rationale: The correct answer is C: Volume overload. In acute kidney injury, impaired kidney function leads to fluid retention, causing volume overload. Dialysis helps remove excess fluid to restore fluid balance. Acidosis and hyperkalemia are potential complications of acute kidney injury but not the primary reasons for initiating dialysis. Hypokalemia is unlikely in acute kidney injury due to impaired excretion of potassium by the kidneys. Therefore, the most common reason for initiating dialysis in acute kidney injury is to manage volume overload.
Question 2 of 5
Following an emergency Cesarean delivery, the nurse encourages the new mother to breastfeed her newborn. The client asks why she should breastfeed now. Which information should the nurse provide?
Correct Answer: A
Rationale: The correct answer is A because breastfeeding helps stimulate the uterus to contract, which reduces the risk of postpartum hemorrhage in the mother. When the baby suckles at the breast, it triggers the release of oxytocin, a hormone that causes the uterus to contract. This contraction helps the uterus to return to its pre-pregnancy size and shape, promoting faster healing and reducing bleeding. Choice B is incorrect because lactation initiation is a separate process that involves hormonal changes and milk production, which may not occur immediately after delivery. Choice C is incorrect as bonding can occur through various interactions beyond breastfeeding. Choice D is incorrect as neonatal hypoglycemia is primarily prevented by ensuring the baby receives adequate nutrition, which can also be achieved through other feeding methods besides breastfeeding.
Question 3 of 5
The nurse manager is assisting a nurse with improving organizational skills and time management. Which nursing activity is the priority in pre-planning a schedule for selected nursing activities in the daily assignment?
Correct Answer: B
Rationale: The correct answer is B: Medication administration. This is the priority because medication administration is time-sensitive and crucial for patient safety. It requires precise timing and cannot be delayed. Tracheostomy tube suctioning (A), colostomy care instruction (C), and client personal hygiene (D) are important nursing activities but can be adjusted within the schedule based on patient needs and acuity levels. Prioritizing medication administration ensures that patients receive their medications on time, preventing adverse events and promoting optimal health outcomes.
Question 4 of 5
A client is receiving atenolol (Tenormin) 25 mg PO after a myocardial infarction. The nurse determines the client's apical pulse is 65 beats per minute. What action should the nurse implement next?
Correct Answer: D
Rationale: The correct answer is D: Administer the medication. Atenolol is a beta-blocker used to reduce heart rate and blood pressure. In this scenario, the client's apical pulse of 65 beats per minute is within the normal range for a client taking atenolol after a myocardial infarction. Therefore, the nurse should proceed with administering the medication as prescribed to help maintain the client's heart rate and blood pressure within the therapeutic range. A: Measuring the blood pressure is important but not the immediate next step as the client's heart rate is within the normal range. B: Reassessing the apical pulse is unnecessary since it is already within the normal range for a client on atenolol. C: Notifying the healthcare provider is not indicated as there are no signs of concern with the client's heart rate at 65 bpm.
Question 5 of 5
A child is receiving maintenance intravenous (IV) fluids at the rate of 1000 mL for the first 10 kg of body weight, plus 50 mL/kg per day for each kilogram between 10 and 20. How many milliliters per hour should the nurse program the infusion pump for a child who weighs 19.5 kg?
Correct Answer: B
Rationale: To calculate the IV fluids for a 19.5 kg child: 1. For the first 10 kg: 1000 mL 2. For the weight between 10-20 kg: (19.5 kg - 10 kg) * 50 mL/kg = 475 mL Total IV fluids = 1000 mL + 475 mL = 1475 mL To convert to mL per hour: 1475 mL / 24 hours = ~61 mL/hr Therefore, the correct answer is B (61 mL/hr). Incorrect Choices: A (24 mL/hr): Incorrect, as it doesn't consider the additional fluids for the weight between 10-20 kg. C (73 mL/hr) and D (58 mL/hr): Incorrect, as these values are not obtained from the correct calculation based on the given formula.
