A client is receiving 10 mL/hr of a prescribed regular insulin infusion. The label on the bag reads 50 units of regular insulin in 100 mL of 0.9% saline. How many units of insulin is the client receiving every hour? Fill in the blank. Round your answer to the nearest whole number.

Choice A rationale: Performing active range of motion exercises may not be safe or appropriate immediately following a hemorrhagic stroke.

Choice B rationale: Maintaining the head of bed flat or at a 30-degree position might be used for ischemic strokes but not necessarily for hemorrhagic strokes.

Choice C rationale: Teaching measures to avoid the Valsalva maneuver (straining during activities like defecation) helps prevent sudden increases in intracranial pressure, which can be detrimental after a hemorrhagic stroke.

Choice D rationale: Monitoring for Battle's sign (bruising behind the ears associated with basilar skull fracture) is not relevant in the care of a hemorrhagic stroke.

Choice A rationale: These lab findings, particularly concentrated urine (high specific gravity) and hyponatremia, are consistent with SIADH, where excessive ADH secretion leads to water retention and dilutional hyponatremia.

Choice B rationale: While it can affect sodium levels, Cushing's syndrome typically results in hypernatremia or normal sodium levels rather than hyponatremia.

Choice C rationale: Usually presents with hyponatremia but not specifically with high urine specific gravity or hematocrit.

Choice D rationale: DI is associated with high serum sodium and low urine specific gravity due to excessive excretion of dilute urine.
