What is a minimally acceptable urine output for a patient weighing 75 kg?

Correct Answer: C

Rationale: The correct answer is C (80 mL/hour) because the minimum acceptable urine output for a patient is approximately 0.5-1 mL/kg/hour. For a 75 kg patient, this equates to 37.5-75 mL/hour. Therefore, an output of 80 mL/hour is within this range and is considered minimally acceptable. A: Less than 30 mL/hour is incorrect because it is below the recommended range for a 75 kg patient. B: 37 mL/hour is close to the lower end of the acceptable range, but it is not the minimum acceptable output. D: 150 mL/hour is above the recommended range and would be considered excessive for a 75 kg patient.

Correct Answer: D

Rationale: The correct answer, D, is supported by the fact that providing aggressive care to patients when nurses believe it is futile can lead to personal ethical conflicts and burnout. This is because nurses may experience moral distress when their values conflict with the care they are providing. This can result in emotional exhaustion and decreased job satisfaction, ultimately leading to burnout. Choice A is incorrect because attending funerals can be a way for nurses to process their grief and find closure, rather than creating additional stress. Choice B is incorrect because caring for dying patients can have emotional impacts on nurses, regardless of their professional approach. Choice C is incorrect because balancing care needs with personal emotional needs can be challenging and may not always be achievable.

Correct Answer: B

Rationale: The correct answer is B: Hypoventilation. A PaCO2 of 48 mm Hg indicates an elevated level of carbon dioxide in the blood, which is typically seen in hypoventilation where the lungs are not effectively removing CO2. Hypoventilation leads to respiratory acidosis. Option A is incorrect because hyperventilation would decrease PaCO2 levels. Option C is incorrect as it does not directly relate to PaCO2 levels. Option D is incorrect as increased excretion of HCO3- would not directly affect PaCO2 levels.

Correct Answer: A

Rationale: The correct answer is A: Allowing nurses to work flexible shift durations. This strategy is important in addressing issues associated with the aging workforce because it acknowledges the changing needs and preferences of older nurses. By offering flexible shift durations, older nurses can better manage their work-life balance, reduce physical strain, and continue contributing to the workforce effectively. Choices B, C, and D are incorrect because they do not directly address the specific needs of the aging workforce. Encouraging older nurses to transfer to a less stressful outpatient setting may not align with their career goals. Hiring nurse technicians to assist with patient care may not address the unique experience and expertise of older nurses. Developing a staffing model, while important, does not specifically cater to the needs of aging nurses in terms of flexibility and support.

Correct Answer: B

Rationale: The correct answer is B: Assist with the intubation of the patient. In this scenario, the patient is unconscious and has ingested a potentially harmful substance. Intubation is the first priority to maintain the patient's airway and ensure adequate oxygenation. This step is crucial in preventing aspiration of gastric contents and securing the patient's respiratory status. Inserting a large-bore orogastric tube (choice A) is not the priority as airway management takes precedence. Preparing a syringe with saline (choice C) is unnecessary at this stage. Giving the first dose of activated charcoal (choice D) should only be done after securing the airway to prevent aspiration.

Correct Answer: D

Rationale: Ultrafiltration is the correct answer because it involves the removal of plasma water and low-molecular weight particles by using a pressure or osmotic gradient. During ultrafiltration, the pressure gradient pushes the fluid through a semipermeable membrane, separating the substances based on their molecular size. This process allows for the selective removal of unwanted substances while retaining essential components. Dialysis (choice A) involves the removal of waste products from the blood, but it does not specifically target plasma water and low-molecular weight particles. Diffusion (choice B) is the passive movement of particles from an area of higher concentration to an area of lower concentration and is not specific to the removal of plasma water. Clearance (choice C) refers to the rate at which a substance is removed from the blood and does not involve the mechanism of pressure or osmotic gradient utilized in ultrafiltration.

Correct Answer: A

Rationale: The presence of protein in the glomerular filtrate indicates a problem with renal function because in healthy kidneys, proteins are retained in the blood and not filtered into the urine. If protein is found in the filtrate, it suggests damage to the glomerular filtration barrier. Sodium, creatinine, and red blood cells are normally present in the filtrate and are not indicative of renal dysfunction. Sodium is freely filtered and reabsorbed, creatinine is a waste product of muscle metabolism excreted by the kidneys, and a small number of red blood cells may be filtered due to their small size. Therefore, protein in the glomerular filtrate is the most specific indicator of renal dysfunction.

Correct Answer: A

Rationale: Step 1: Asking if these wishes have been discussed with the healthcare provider is important to ensure that the patient's wishes are documented and considered in the care plan. Step 2: The healthcare provider needs to be aware of the patient's preferences regarding resuscitation to provide appropriate care. Step 3: This step helps in clarifying the patient's preferences and ensures that the healthcare team follows the patient's wishes. Step 4: Placing a DNR notation without consulting the healthcare provider may not align with the patient's overall care plan and may lead to potential legal and ethical issues. Step 5: Informing the patient about notarized advance directives and designating a person for healthcare decisions are important but not the immediate step needed in this scenario. In summary, choice A is correct as it prioritizes communication with the healthcare provider to ensure the patient's wishes are properly documented and followed. Choices B, C, and D are incorrect because they do not involve confirming the patient's wishes
