Critical Care Nursing Questions Questions

Question 1 of 5

A 100-kg patient gets hemodialysis 3 days a week. In planning the care for this patient, the nurse recommends

Correct Answer: A

Rationale: The correct answer is A: a diet of 2500 to 3500 kcal per day. During hemodialysis, the patient loses nutrients and energy, so a high-calorie diet is necessary to maintain proper nutrition and energy levels. 2500-3500 kcal/day is a suitable range for a 100-kg patient. Choice B is incorrect because protein intake should be adequate to prevent malnutrition in hemodialysis patients, typically 1.2g/kg body weight/day. Choice C is incorrect as potassium intake should be restricted in hemodialysis patients due to impaired kidney function. Choice D is incorrect because fluid intake should be individualized based on the patient's fluid status and should not be limited to less than 500 mL per day.

Question 2 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 3 of 5

The nurse is preparing to administer atropine, an anticholinergic, to a client scheduled for a cholecystectomy. The client asks the nurse to explain the reason for the prescribed medication. What response is best for the nurse to provide?

Correct Answer: C

Rationale: The correct answer is C: Decrease the risk of bradycardia during surgery. Rationale: 1. Atropine is an anticholinergic medication that works by blocking the parasympathetic nervous system. 2. During surgery, the parasympathetic stimulation can lead to bradycardia (slow heart rate). 3. By administering atropine, the nurse can counteract the bradycardic effects and maintain a normal heart rate during the procedure. 4. Options A, B, and D are incorrect as atropine is not used for inducing anesthesia, relaxation, or minimizing postoperative analgesia.

Question 4 of 5

A nurse is on a committee that is trying to reduce the occurrence of hospital-acquired infections in the ICU. Her role is to conduct research to find which interventions have been shown to be most effective in reducing these infections. She consults many different sources and finds conflicting information. Which of the following sources should she consider the most authoritative?

Correct Answer: B

Rationale: The correct answer is B: A meta-analysis of randomized controlled trials in the American Journal of Nursing. 1. Meta-analyses provide a comprehensive overview of multiple studies, increasing the reliability of the findings. 2. Randomized controlled trials are considered the gold standard in research design for assessing intervention effectiveness. 3. The American Journal of Nursing is a reputable source in the field of nursing, ensuring the credibility of the study. 4. By synthesizing data from various trials, the meta-analysis can offer a more robust and generalizable conclusion compared to a single trial or qualitative studies. Incorrect choices: A: AACN expert panel report - Expert opinions may vary and lack the empirical evidence provided by research studies. C: A systematic review of qualitative studies in the Journal of Advanced Nursing - Qualitative studies may provide valuable insights but may not offer concrete evidence on intervention effectiveness like quantitative studies. D: A single randomized controlled trial in the American Journal of Critical Care - Single trials may not capture the full picture and

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.
