A patient who has been declared brain dead is considered a potential organ donor. In order to proceed with donation, the nurse must understand that applicable concept?
- A. A signed donor card mandates that organs be retrieved in the event of brain death.
- B. After brain death has been determined, perfusion and o xygenation of organs is maintained until organs can be removed in the operatin ag bi rbro .co omm /t. e st
- C. The healthcare proxy does not need to give consent for the retrieval of organs.
- D. Once a patient has been established as brain dead, life support is withdrawn and organs are retrieved.
Correct Answer: B
Rationale: The correct answer is B because after brain death is confirmed, maintaining perfusion and oxygenation of organs is crucial to ensure their viability for donation. This process allows organs to be retrieved in optimal condition during the operation. Choice A is incorrect because a signed donor card is not a legal mandate for organ retrieval. Choice C is incorrect as the healthcare proxy's consent is typically required for organ donation. Choice D is incorrect because life support is not immediately withdrawn upon brain death confirmation; instead, organ preservation measures are initiated.

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?
- A. 24
- B. 61
- C. 73
- D. 58
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.
The nurse is a member of a committee to design a critical care unit in a new building. Which design trend would best be implemented to facilitate famil y-centered care?
- A. Ensuring that the patient’s room is large enough to inc lude a sleeper sofa and storage for family members’ personal belongings.
- B. Including a diagnostic suite in close proximity to the u nit so that the patient does not have to travel far for testing.
- C. Incorporating a large waiting room on the top floor of athbierb .hcooms/pteistta l with a scenic view and amenities such as coffee and tea.
- D. Providing access to a scenic garden for meditation.
Correct Answer: A
Rationale: Correct Answer: A
Rationale:
1. Family-centered care promotes involvement of family members in patient care.
2. A sleeper sofa in the patient's room allows family members to stay overnight, enhancing support for the patient.
3. Storage for personal belongings ensures families can have essentials close by, increasing comfort and convenience.
4. These design elements facilitate family presence, communication, and participation in care, aligning with family-centered care principles.
Summary of Incorrect Choices:
B. Having a diagnostic suite nearby is convenient but not directly related to family-centered care principles.
C. A waiting room with amenities is beneficial but does not directly involve families in patient care.
D. Access to a garden for meditation is helpful for relaxation but does not emphasize family involvement in care.
The patient is receiving neuromuscular blockade. Which nursing assessment indicates a target level of paralysis?
- A. Glasgow Coma Scale score of 3
- B. Train-of-four yields two twitches
- C. Bispectral index of 60
- D. CAM-ICU positive
Correct Answer: B
Rationale: The correct answer is B: Train-of-four yields two twitches. This assessment indicates a target level of paralysis because a train-of-four ratio of 2 twitches out of 4 suggests a 50% neuromuscular blockade, which is often the goal for patients receiving paralysis for procedures or ventilation.
A: A Glasgow Coma Scale score of 3 assesses consciousness, not neuromuscular blockade.
C: A Bispectral index of 60 measures depth of anesthesia, not paralysis level.
D: CAM-ICU assesses delirium, not neuromuscular blockade.
Positive end-expiratory pressure (PEEP) is a mode of ventaiblairbto.croym /atessst istance that produces which of the following conditions
- A. Each time the patient initiates a breath, the ventilator d elivers a full preset tidal volume.
- B. For each spontaneous breath taken by the patient, the tidal volume is determined by the patient’s ability to generate negative pressure.
- C. The patient must have a respiratory drive, or no breaths will be delivered.
- D. There is pressure remaining in the lungs at the end of eaxbiprbi.rcaotmio/tens tt hat is measured in cm H O.
Correct Answer: D
Rationale: The correct answer is D because positive end-expiratory pressure (PEEP) is a mode of ventilation where pressure is maintained in the lungs at the end of expiration. This helps prevent alveolar collapse and improves oxygenation. Option A is incorrect because PEEP does not deliver a full preset tidal volume with each breath initiation. Option B is incorrect because tidal volume in PEEP is not solely determined by the patient's ability to generate negative pressure. Option C is incorrect because in PEEP, breaths are delivered irrespective of the patient's respiratory drive.
What is the most common cause of a pulmonary embolus?
- A. An amniotic fluid embolus.
- B. A deep vein thrombosis from lower extremities.
- C. A fat embolus from a long bone fracture.
- D. Vegetation that dislodges from an infected central venous catheter.
Correct Answer: B
Rationale: The correct answer is B: A deep vein thrombosis from lower extremities. Deep vein thrombosis (DVT) is the most common cause of a pulmonary embolus as a blood clot can dislodge from the veins, travel to the lungs, and block blood flow. An amniotic fluid embolus (Choice A) occurs during childbirth and is rare as a cause of pulmonary embolism. A fat embolus (Choice C) typically occurs after a long bone fracture and is more likely to cause issues in the lungs. Vegetation from an infected central venous catheter (Choice D) can cause septic pulmonary embolism, but it is not as common as DVT.
