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.

When preparing to cool a patient who is to begin therapeutic hypothermia, which intervention will the nurse plan to do (select all that apply)?
- A. Assist with endotracheal intubation.
- B. Insert an indwelling urinary catheter.
- C. Begin continuous cardiac monitoring.
- D. Obtain an order to restrain the patient.
Correct Answer: C
Rationale: Rationale:
Continuous cardiac monitoring is crucial during therapeutic hypothermia to monitor the patient's cardiac rhythm and detect any arrhythmias promptly. This intervention allows for immediate intervention if any cardiac issues arise.
Explanation of other choices:
A: Assisting with endotracheal intubation may be necessary for airway management but is not directly related to cooling the patient for therapeutic hypothermia.
B: Inserting an indwelling urinary catheter may be needed for urine output monitoring but is not a priority intervention for cooling the patient.
D: Restraining the patient is unnecessary and not indicated for therapeutic hypothermia; it may cause unnecessary distress and should be avoided unless absolutely necessary for patient safety.
The patient is admitted with complaints of general malaise and fatigue, along with a decreased urinary output. The patient’s urinalysis shows coarse, muddy brown granular casts and hematuria. The nurse determines that the patient has:
- A. acute kidney injury from a prerenal condition.
- B. acute kidney injury from postrenal obstruction.
- C. intrarenal disease, probably acute tubular necrosis.
- D. a urinary tract infection.
Correct Answer: C
Rationale: The correct answer is C: intrarenal disease, probably acute tubular necrosis. The patient's symptoms of general malaise, fatigue, decreased urinary output, along with the presence of coarse, muddy brown granular casts and hematuria in the urinalysis indicate kidney damage. Acute tubular necrosis is a common cause of acute kidney injury characterized by damage to the renal tubules, leading to impaired kidney function. The presence of granular casts and hematuria suggests tubular injury and bleeding within the kidney. Choices A and B are incorrect as they refer to prerenal and postrenal causes of kidney injury, respectively, which do not align with the patient's symptoms and urinalysis findings. Choice D is incorrect as a urinary tract infection would typically present with different symptoms and urinalysis findings.
The nurse is caring for a patient who is mechanically ventilated. The nurse understands that what statement should be considered when determining apapbrirob.pcormia/ttees tn ursing interventions?
- A. Communication with intubated patients is often difficult.
- B. Controlled ventilation is the preferred mode for most p atients.
- C. Patients with chronic obstructive pulmonary disease w ean easily from mechanical ventilation.
- D. Wrist restraints are applied to all patients to avoid self- extubation.
Correct Answer: A
Rationale: The correct answer is A because communication with intubated patients is often challenging due to the presence of an artificial airway, which hinders speech. This understanding is crucial when determining appropriate nursing interventions to ensure effective patient care.
Choice B is incorrect because different patients may require different modes of ventilation based on their specific condition, and controlled ventilation may not always be the preferred mode for all patients.
Choice C is incorrect as patients with chronic obstructive pulmonary disease often have difficulty weaning from mechanical ventilation due to their underlying respiratory condition.
Choice D is incorrect as wrist restraints are not applied to all patients on mechanical ventilation unless absolutely necessary for safety concerns, such as preventing self-extubation.
A critically ill patient experiences stress and anxiety from many factors. Treatment of the patient focuses on reducing stressors and providing supportive care such as nutrition, oxygenation, pain management, control of anxiety, and specific care of the illness or injury. What is the best rationale for these interventions?
- A. Helps to support the patients immune system
- B. Part of good nursing care
- C. Mandated by hospital policy
- D. Reassures the patient and family
Correct Answer: A
Rationale: The correct answer is A: Helps to support the patient's immune system. Providing supportive care such as nutrition, oxygenation, pain management, and anxiety control can help reduce stress, which in turn supports the immune system. Stress weakens the immune system, making the patient more vulnerable to infections and complications. By addressing stress and anxiety through supportive care, the patient's immune system is better able to function optimally, aiding in the recovery process.
Choices B, C, and D are incorrect because:
B: Part of good nursing care - While supportive care is indeed part of good nursing care, the key rationale for these interventions in a critically ill patient is to support the immune system, not just to provide good nursing care.
C: Mandated by hospital policy - Hospital policies may dictate certain aspects of care, but the primary goal of these interventions is to support the patient's immune system, not just to comply with hospital policies.
D: Reassures the patient and family - While providing reass
Which of the following nursing activities demonstrates im plementation of the AACN Standards of Professional Performance? (Select all that ap ply.)
- A. Attending a meeting of the local chapter of the Americ an Association of Critical-Care Nurses in which a continuing education program on sepsis is being taught
- B. Collaborating with a pastoral services colleague to assist in meeting spiritual needs of the patient and family
- C. Participating on the unit’s nurse practice council
- D. Posting an article from Critical Care Nurse on manage ment of venous thromboembolism for your colleagues to read
Correct Answer: C
Rationale: The correct answer is C because participating on the unit's nurse practice council demonstrates adherence to the AACN Standards of Professional Performance, specifically the standard related to quality of practice. By actively engaging in the nurse practice council, the nurse contributes to the development and implementation of policies and procedures that promote quality patient care. This activity also involves collaboration, leadership, and advocacy, which are essential components of professional nursing practice.
The other choices are incorrect because:
A: Attending a meeting and receiving continuing education on sepsis is important for professional development but does not directly align with the AACN Standards of Professional Performance.
B: Collaborating with a pastoral services colleague is essential for holistic patient care but does not specifically address the standards set by the AACN.
D: Posting an article for colleagues to read is beneficial for knowledge sharing but does not directly demonstrate adherence to the AACN Standards of Professional Performance.
