Answer and Explanation

The Correct Answer is ["32"]

1. Determine the concentration of heparin in the solution:

- There are 25,000 units of heparin in 500 mL of D5W.

- Concentration = 25,000 units / 500 mL = 50 units/mL.

2. Calculate the required mL/hr for the desired infusion rate:

- The order is for 1600 units/hr.

- To find the mL/hr:

ML/HR=desired units/hr divided by unts/ml

=1600/50

=32ml/hr

Correct Answer is A

Explanation

A. Hematuria: This is the correct answer. Hematuria, which is the presence of blood in the urine, can be a common complication of pelvic fractures. This occurs due to the potential injury to the bladder or other structures within the pelvis. Monitoring for hematuria is crucial in assessing potential internal injuries and ensuring appropriate management.

B. Impaired taste: Impaired taste is not typically associated with pelvic fractures. It is more likely related to conditions involving the sense of taste or other unrelated factors. It is not a common complication of pelvic fractures.

C. Diarrhea: Diarrhea is not a common complication of pelvic fractures. It is more likely to be caused by gastrointestinal issues, infections, dietary factors, or other medical conditions. It is not directly related to pelvic fractures or their complications.

D. Increased thirst: Increased thirst is not a common complication of pelvic fractures. It may be related to various factors such as dehydration, certain medical conditions like diabetes, or side effects of medications. It is not a direct consequence of pelvic fractures or their associated complications.

A. Insert sterile packing into the nares. B. Allow the drainage to drip onto a sterile gauze pad. C. Suction the nose gently with a bulb syringe. D. Obtain a culture of the specimen using sterile swabs.

Correct Answer is B

Explanation

A. Inserting sterile packing into the nares is not indicated in this situation. Clear fluid drainage from the nose may be cerebrospinal fluid (CSF), and packing could cause further complications.

B. Allowing the drainage to drip onto a sterile gauze pad is the appropriate initial action. Clear fluid drainage from the nose after a traumatic event may be CSF, which can indicate a skull fracture and damage to the meninges. Collecting the fluid on a sterile gauze pad can help confirm the presence of CSF.

C. Suctioning the nose with a bulb syringe is not recommended because it can introduce contaminants into the nasal passages and potentially worsen the injury.

D. Obtaining a culture of the specimen using sterile swabs is a consideration once the presence of CSF is confirmed. However, the initial priority is to identify and collect the clear fluid drainage.
