Decreased serum osmolarity

Decreased hematocrit

Elevated blood urea nitrogen (BUN)

Answer and Explanation

The Correct Answer is C

A. Decreased serum osmolarity: Fluid volume deficit typically leads to an increase in serum osmolarity due to concentration of solutes in the blood, not a decrease.

B. Decreased hematocrit: Dehydration causes hemoconcentration, leading to an increase in hematocrit, not a decrease.

C. Elevated blood urea nitrogen (BUN): Dehydration results in decreased renal perfusion and concentration of urea in the blood, leading to elevated BUN levels.

Correct Answer is A

Explanation

A. Discarding opened cans of formula after 24 hours helps prevent bacterial contamination and growth, which can contribute to diarrhea in clients receiving enteral feedings.

B. Extension tubing should be replaced according to institutional policy and manufacturer recommendations, typically every 24 to 48 hours, but it is not directly related to diarrhea management.

C. Irrigating the tubing with warm water is not a standard practice for managing diarrhea in clients receiving enteral feedings and may disrupt the client's fluid and electrolyte balance.

D. Increasing the infusion rate of enteral feedings is not indicated for managing diarrhea and may exacerbate the problem by overwhelming the client's gastrointestinal tract. The rate of enteral feeding should be adjusted based on the client's nutritional needs and tolerance, as determined by the healthcare provider.

A. Metoprolol B. Clopidogrel C. Metformin D. Digoxin

Correct Answer is C

Explanation

A. Metoprolol is a beta-blocker used to treat hypertension and other cardiovascular conditions.

While it may be important for the provider to be aware of all medications, it is not the priority to report in this scenario.

B. Clopidogrel is an antiplatelet medication used to prevent blood clots in individuals at risk for cardiovascular events. While it may have implications for the procedure, it is not the priority to report in this scenario.

C. Metformin is an oral antidiabetic medication commonly used to treat type 2 diabetes. It is

important to report because there may be specific considerations regarding its use in the context of a colonoscopy, such as the risk of lactic acidosis.
