Intrapulmonary shunting refers to what outcome?
- A. Alveoli that are not perfused.
- B. Blood that is shunted from the left side of the heart to t he right and causes heart failure.
- C. Blood that is shunted from the right side of the heart to the left without oxygenation.
- D. Shunting of blood supply to only one lung.
Correct Answer: C
Rationale: Step-by-step rationale for why choice C is correct:
1. Intrapulmonary shunting refers to blood bypassing the normal oxygenation process in the lungs.
2. Choice C describes blood being shunted from the right side of the heart (deoxygenated blood) to the left side without oxygenation, leading to systemic circulation without oxygenation.
3. Choices A, B, and D do not accurately describe intrapulmonary shunting as they focus on other concepts like alveolar perfusion, heart failure, and unilateral lung blood supply, respectively.

The nursing is caring for a patient who has had an arterial line inserted. To reduce the risk of complications, what is the priority nursing intervention?
- A. Apply a pressure dressing to the insertion site.
- B. Ensure all tubing connections are tightened.
- C. Obtain a portable x-ray to confirm placement.
- D. Restrain the affected extremity for 24 hours.
Correct Answer: C
Rationale: The correct answer is C: Obtain a portable x-ray to confirm placement. This is the priority intervention because it ensures the arterial line is correctly positioned, reducing the risk of complications such as dislodgement or improper placement. Applying a pressure dressing (choice A) may be necessary but is not the priority. Ensuring tubing connections are tightened (choice B) is important for preventing leaks but does not address placement. Restraining the affected extremity (choice D) is unnecessary and can lead to complications. The x-ray confirms correct placement, ensuring accurate monitoring and treatment.
A family member tells the nurse, 'I don’t know how I’m going to manage without my mother. She took care of everything for us.' Which response by the nurse is most appropriate?
- A. You will learn how to manage things gradually, and I can provide some resources to help you.
- B. It will be difficult at first, but time will help you adjust to her loss.
- C. Perhaps another family member can take over the responsibilities your mother managed.
- D. It sounds like you will need to seek professional counseling to cope with this loss.
Correct Answer: A
Rationale: The correct answer is A because it acknowledges the family member's feelings while offering support and resources for managing the situation gradually. By providing resources, the nurse empowers the family member to learn how to handle things independently over time. This approach promotes self-reliance and resilience.
Choice B focuses on time rather than active coping strategies, which may not address the family member's immediate needs. Choice C suggests shifting responsibilities to another family member without considering the emotional impact. Choice D jumps to the conclusion of needing professional counseling without exploring other potential solutions or support systems.
The transplant clinic coordinator is evaluating relatives of a patient with end-stage renal disease, whose blood type is A positive, for suitability as aa bliirvb.icnogm /dteostn or for kidney transplantation. Which family member best qualifies for evaluation?
- A. A 65-year-old brother with a history of hypertension; b lood type A positive
- B. A 35-year-old female with a history of food allergies; blood type O negative
- C. A 14-year-old son, otherwise healthy with no history; blood type B negative
- D. A 70-year-old mother, with a history of sinus infection s; blood type A positive
Correct Answer: D
Rationale: The correct answer is D, the 70-year-old mother with blood type A positive. This choice is the best candidate for evaluation due to her blood type matching the patient's (A positive) for kidney transplantation. Age and medical history are also crucial factors in determining suitability. The 65-year-old brother (choice A) has hypertension, a significant risk factor. The 35-year-old female (choice B) with food allergies may have potential complications. The 14-year-old son (choice C) is underage and might not be a suitable donor due to age and the potential impact on his growth and development. In summary, choice D aligns with the matching blood type and age, making the mother the most suitable candidate for evaluation.
A patient declared brain dead is an organ donor. The following events occur: 1300 Diagnostic tests for brain death are completed. 1330 primary care provider reviews diagnostic test results and writes in the progress note that the patient is brain deaadb.i r1b.4co0m0/ tePsat tient is taken to the operating room for organ retrieval. 1800 All organs have b een retrieved for donation. The ventilator is discontinued. 1810 Cardiac monitor shows fla tline. What is the official time of death recorded in the medical record?
- A. 1300
- B. 1330
- C. 1400
- D. 1800
Correct Answer: E
Rationale: The correct answer is not provided, but based on the events described, the official time of death recorded in the medical record should be 1810 (Choice D). At this time, the cardiac monitor shows flatline, indicating the cessation of cardiac activity, which is the universally accepted point of declaring death.
Choice A (1300) is incorrect because that is when diagnostic tests for brain death were completed, but the patient was not officially declared dead at that time.
Choice B (1330) is incorrect as this is when the primary care provider reviewed the test results and documented brain death in the progress note, but the patient was not officially declared dead at this time either.
Choice C (1400) is incorrect as there is no significant event occurring at this time that signifies the patient's death.
Therefore, the most appropriate and official time of death recorded in the medical record would be 1810 when the cardiac monitor shows flatline.
The nurse obtains the pulse rate of 89 beats/minute for an infant before administering digoxin (Lanoxin). Which action should the nurse take?
- A. Withhold the medication and contact the healthcare provider.
- B. Give the medication dosage as scheduled.
- C. Assess respiratory rate for one minute next.
- D. Wait 30 minutes and give half of the dosage of medication.
Correct Answer: A
Rationale: The correct answer is A. Infants typically have higher resting heart rates than adults, so a pulse rate of 89 beats/minute for an infant may indicate bradycardia. Digoxin can further lower the heart rate, leading to potential adverse effects like arrhythmias. Therefore, withholding the medication and contacting the healthcare provider is crucial to ensure the safety of the infant.
Choice B is incorrect because administering digoxin without addressing the elevated pulse rate can be dangerous. Choice C is incorrect as assessing respiratory rate does not address the immediate concern of the elevated pulse rate. Choice D is also incorrect as waiting and giving half of the dosage may further exacerbate the situation.
