A nurse is preparing to administer Ringer’s lactate via continuous IV infusion at a rate of 120 mL/hr. The manual IV tubing’s drop factor is 60 gtt/mL. How many gtt/min should the nurse set the manual IV infusion to deliver?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A rationale

The glomerular filtration rate (GFR) does not recover during the oliguric phase of acute kidney injury (AKI). Recovery of GFR typically occurs during the recovery phase.

Choice B rationale

During the oliguric phase of AKI, urine output is typically less than 400 mL per 24 hours.

Choice C rationale

Renal function is not reestablished during the oliguric phase of AKI. This typically occurs during the recovery phase.

Choice D rationale

Blood urea nitrogen (BUN) and creatinine levels do not decrease during the oliguric phase of AKI. These levels typically increase due to decreased kidney function.

Choice A rationale

The symptoms described, including the paradoxical movement of the chest wall (moving inward during inspiration and outward during expiration), are indicative of a flail chest, which is a life-threatening condition that occurs when a segment of the rib cage breaks due to trauma and becomes detached from the rest of the chest wall.

Choice B rationale

Hemothorax is a collection of blood in the space between the chest wall and the lung (the pleural cavity). It’s often caused by chest trauma. It does not cause the chest to move inward during inspiration and outward during expiration.

Choice C rationale

Atelectasis is a complete or partial collapse of the entire lung or area (lobe) of the lung. It does not cause the chest to move inward during inspiration and outward during expiration.

Choice D rationale

Pneumothorax is a collapsed lung. It does not cause the chest to move inward during inspiration and outward during expiration.
