AACN CCRN (Adult) - Direct Care Eligibility Pathway Sample Questions (Q716-Q721):
NEW QUESTION # 716
Which of the following types of acute kidney injury is a urinary tract infection MOST LIKELY to cause?
Answer: C
Explanation:
Postrenal acute kidney injury is an acute kidney injury that is caused by conditions distal to the kidneys in the ureters, bladder, or urethra. A urinary tract infection can cause obstruction of the drainage of urine, leading urine to back up into the kidneys and causing postrenal acute kidney injury. Intrarenal acute kidney injury refers to kidney injury that occurs from a cause within the kidneys themselves, while prerenal acute kidney injury refers to kidney injuries caused by decreased blood supply to the kidneys.
NEW QUESTION # 717
A family member asks permission to visit a patient after work at 12:30 AM. On previous visits, the family member has been disruptive. To address the situation, a nurse should
Answer: D
Explanation:
While it is important to support family involvement, previous disruptive behavior necessitates setting clear behavioral limits to ensure a safe and therapeutic environment for the patient. Allowing the visit with established guidelines helps balance the need for patient support with maintaining unit order. This approach also respects the patient's rest and recovery needs.

NEW QUESTION # 718
A 69-year-old female presented to the emergency department with diaphoresis and severe dyspne a. A pulse oximeter revealed 85% oxygen saturation. Oxygen at 4 L/min was started via nasal cannula, and an ECG was performed and showed left ventricular hypertrophy and a Left Bundle Branch Block (LBBB). Her chest x-ray showed an enlarged cardiac silhouette and bilateral infiltrates. The nurse secured IV access, and the patient was started on a dobutamine drip and given IV furosemide.
The PRIMARY purpose of starting the dobutamine infusion and administering the furosemide is to:
Answer: D
Explanation:
This patient is exhibiting signs and symptoms of Heart Failure (HF). Regardless of the underlying cause of the weak pump of the heart, patients with HF present with signs and symptoms of intravascular and interstitial volume overload, as well as manifestations of inadequate tissue perfusion. Diuretic therapy is often initiated (to manage the fluid volume overload) to decrease ventricular preload. In addition, limitation of dietary sodium, and restriction of free water is implemented. Dobutamine is given to improve ventricular function by augmenting ventricular contractility (inotropic agent).
NEW QUESTION # 719
Which of the following is NOT one of the main methods initially used to diagnose injury of a patient who has experienced abdominal trauma?
Answer: A
Explanation:
An abdominal X-ray would not provide significant information about many of the injuries that may occur with abdominal trauma, as many of the organs affected consist of soft tissues that will not be easily accessible by a simple single-view X-ray. A focused assessment with sonography for trauma (FAST) exam, CAT scan, and physical assessment are all important methods used to diagnose injury for someone who has experienced abdominal trauma.
NEW QUESTION # 720
Which of the following injuries is MOST LIKELY to create flail chest?
Answer: A
Explanation:
Flail chest occurs when several (3 or more) adjacent ribs are fractured in at least two places. This creates a "floating segment" of the chest that may puncture the lung and compromise oxygenation and ventilation, preventing normal expansion and reduction of the lung when breathing.
Symptoms of flail chest include chest pain and shortness of breath. On assessment, there is inward movement of the affected side of the chest during inspiration and outward movement during expiration, called "paradoxical breathing." This injury is best assessed when the patient is breathing spontaneously.
Bilateral single rib fractures may theoretically cause flail chest, but only if the sternum becomes fully detached from the ribs.
