What factors may predispose a patient to respiratory acido as bi is rb? . com/test
- A. Anxiety and fear
- B. Central nervous system depression
- C. Diabetic ketoacidosis
- D. Nasogastric suctioning
Correct Answer: B
Rationale: The correct answer is B: Central nervous system depression. This factor can lead to respiratory acidosis by depressing the respiratory drive, causing hypoventilation and retention of carbon dioxide. Anxiety and fear (A) may lead to hyperventilation, reducing carbon dioxide levels. Diabetic ketoacidosis (C) results in metabolic acidosis, not respiratory acidosis. Nasogastric suctioning (D) may cause respiratory alkalosis from excessive removal of carbon dioxide. Thus, central nervous system depression is the most likely factor predisposing a patient to respiratory acidosis.

Which patient should the nurse notify the organ procureme nt organization (OPO) to evaluate for possible organ donation?
- A. A 36-year-old patient with a Glasgow Coma Scale score of 3 with no activity on electroencephalogram
- B. A 68-year-old male admitted with unstable atrial fibrillation who has suffered a stroke
- C. A 40-year-old brain-injured female with a history of ovabairrbi.acnom c/taenstc er and a Glasgow Coma Scale score of 7
- D. A 53-year-old diabetic male with a history of unstable angina status post resuscitation
Correct Answer: A
Rationale: The correct answer is A because the patient is a 36-year-old with a Glasgow Coma Scale score of 3 and no activity on electroencephalogram, indicating severe brain injury and likely irreversible neurological damage. This patient meets the criteria for potential organ donation as they are neurologically devastated.
Choice B is incorrect because the patient's condition is related to stroke and atrial fibrillation, not severe brain injury that would make them a candidate for organ donation.
Choice C is incorrect because although the patient has a brain injury and a lower Glasgow Coma Scale score, the history of a reversible cause (ovarian cancer metastasis) and a higher GCS score compared to choice A make this patient less suitable for organ donation evaluation.
Choice D is incorrect as the patient's diabetic and cardiovascular history does not suggest severe brain injury that would qualify for organ donation.
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.
The nurse is preparing to provide postmortem care for a patient who has just died. Which action should the nurse take first?
- A. Close the patient’s eyes and place a pillow under the head.
- B. Wash the patient’s body and apply a clean gown.
- C. Remove all medical equipment and tubes.
- D. Confirm that a death certificate has been signed.
Correct Answer: A
Rationale: Rationale:
A: Closing the patient's eyes and placing a pillow under the head is the first step in postmortem care to maintain dignity and prevent airway occlusion.
B: Washing the body and changing clothes can be done later and is not the priority.
C: Removing medical equipment can wait until after ensuring the patient's comfort.
D: Confirming the death certificate is important but not the immediate first step in postmortem care.
A client has been admitted after experiencing multiple trauma and is intubated and sedated. When the five members of the immediate family arrive, they are anxious, angry, and very demanding. They all speak loudly at once and ask for many services and answers. What is the best nursing response?
- A. Ask the family to leave until visiting hours begin.
- B. Take them to a private area for initial explanations.
- C. Page security to have them removed from unit.
- D. Show them to the clients bedside and leave them alone.
Correct Answer: B
Rationale: The correct answer is B: Take them to a private area for initial explanations. This response is the best because it allows the nurse to address the family's concerns in a private and controlled environment. It promotes effective communication and enables the family to express their emotions and receive information without distractions.
Choice A is incorrect because asking the family to leave may escalate the situation and not address their needs. Choice C is inappropriate as paging security to remove the family can worsen the family's distress and hinder communication. Choice D is not ideal as leaving the family alone may lead to misunderstandings and increased anxiety. Overall, choice B is the most therapeutic and effective approach in this situation.
The nurse returns from the cardiac catheterization laboratory with a patient following insertion of a pulmonary artery catheter and assists in transferring th e patient from the stretcher to the bed. Prior to obtaining a cardiac output, which action is m ost important for the nurse to complete?
- A. Document a pulmonary artery catheter occlusion press ure.
- B. Zero reference the transducer system at the phlebostatic axis.
- C. Inflate the pulmonary artery catheter balloon with 1 m L air.
- D. Inject 10 mL of 0.9% normal saline into the proximal port.
Correct Answer: B
Rationale: The correct answer is B: Zero reference the transducer system at the phlebostatic axis. This is the most important action before obtaining a cardiac output because zero referencing ensures accurate pressure readings. The phlebostatic axis is the level of the atria when the patient is supine, and zeroing at this point minimizes errors in pressure measurements.
Choice A is incorrect because documenting a pulmonary artery catheter occlusion pressure is not the priority at this stage. Choice C is incorrect as inflating the balloon with air should be done after zero referencing. Choice D is incorrect as injecting normal saline into the port is not necessary before zero referencing.
