A nurse is preparing to administer 40 mEq of potassium chloride in 45% sodium chloride (NaCl) 500 mL IV to infuse 10 mEq/hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A Reason: This choice is correct because allowing the drainage to drip onto a sterile gauze pad may help to identify if it is cerebrospinal fluid (CSF), which is a clear fluid that surrounds and protects the brain and spinal cord. CSF leakage from the nose (rhinorrhea) may indicate a basilar skull fracture, which is a serious injury that can cause intracranial bleeding, infection, or brain damage. The nurse should test the drainage for the presence of glucose or the halo sign, which are indicators of CSF.

Choice B Reason: This choice is incorrect because obtaining a culture of the specimen using sterile swabs may introduce bacteria into the nasal cavity and increase the risk of infection. The nurse should avoid inserting anything into the nose or mouth of a client who has a suspected basilar skull fracture.

Choice C Reason: This choice is incorrect because inserting sterile packing into the nares may increase the pressure in the cranial cavity and worsen the injury. The nurse should avoid applying pressure or occluding the nose or ears of a client who has a suspected basilar skull fracture.

Choice D Reason: This choice is incorrect because suctioning the nose gently with a bulb syringe may damage the nasal mucosa and cause bleeding. The nurse should avoid suctioning or irrigating the nose or ears of a client who has a suspected basilar skull fracture.

Choice A Reason: Cause of the burn is not the nurse's priority when assessing the severity of the client's burns. The cause of the burn may indicate the type and duration of exposure, such as thermal, chemical, electrical, or radiation, which can affect the depth and extent of injury. However, these factors are secondary to ensuring adequate oxygenation and ventilation.

Choice B Reason: Age of the client is not the nurse's priority when assessing the severity of the client's burns. The age of the client may influence the response to burn injury, such as healing time, infection risk, and fluid requirements.

However, these factors are secondary to ensuring adequate oxygenation and ventilation.

Choice C Reason: Associated medical history is not the nurse's priority when assessing the severity of the client's burns. The associated medical history may affect the outcome and prognosis of burn injury, such as pre-existing conditions, medications, or allergies. However, these factors are secondary to ensuring adequate oxygenation and ventilation.

Choice D Reason: Location of the burn is the nurse's priority when assessing the severity of the client's burns. The location of the burn can indicate the potential for life-threatening complications, such as airway obstruction, inhalation injury, or impaired circulation. The nurse should assess for signs and symptoms of respiratory distress, such as stridor, wheezes, or cyanosis, and prepare for endotracheal intubation if needed. The nurse should also monitor for signs and symptoms of compartment syndrome, such as pain, pallor, paresthesia, pulselessness, or paralysis, and report any findings to the provider. The location of the burn can also affect the functional and cosmetic outcomes, such as vision loss, facial disfigurement, or joint contractures. The nurse should provide appropriate wound care, pain management, and rehabilitation as prescribed. Assessing for location of burn is essential to prevent further injury and preserve vital functions.
