Question 1

When checking intracranial pressure in an adult, the trauma nurse must be informed of what the usual range is?

Accepted Answer

10 to 15 mm Hg.

Answer

The trauma nurse must be aware that the typical range for intracranial pressure in adults is 10 to 15 mm Hg when doing so.  When there is internal bleeding in the brain, the brain initially tries to reduce the volume of CSF by increasing absorption and decreasing blood flow, but when the brain is unable to do so, the ICP starts to rise very quickly, which can sometimes cause brain shift and herniation syndromes as well as compression of the tissue. If the disease is not corrected right away, death might occur in a matter of hours.

Question 2

When there is an abdominal gunshot wound, the trauma nurse should predict that the organ most likely to be damaged is ?

Accepted Answer

small intestine

Answer

The small intestine (which accounts for half of injuries) is the organ that the trauma nurse should expect to be hurt when a gunshot wound to the abdomen occurs. However, a number of other organs (including the colon, liver, and major veins) could also be hurt depending on the bullet's trajectory and depth of penetration. Close-range high-energy bullet wounds can cause both primary injuries and secondary injuries, such those from broken bones.

Question 3

A 40-year-old person with cardiac arrhythmias is given mannitol to lower elevated intracranial pressure brought on by a traumatic brain injury. The arrhythmias are most likely caused by which of the following electrolyte imbalances connected to mannitol administration?

Accepted Answer

Hyperkalemia

Answer

When mannitol is administered to treat cerebral edema, it may lead to hyperkalemia, a fluid and electrolyte imbalance, and cardiac arrhythmias. An osmotic diuretic called mannitol reduces intracranial pressure and brain mass, especially after traumatic brain injury. It also increases potassium levels and salt and water excretion. Urticaria, hypotension, tachycardia, fever, and vomiting are a few other side effects. The blood-brain barrier's cells may be reduced in size with mannitol in order to facilitate the passage of other drugs through it. After injection, cerebral spinal fluid pressure should start to drop within 15 minutes.

Question 4

When withdrawing and securing a pistol from a trauma victim's pocket, what should they first think about?

Accepted Answer

avoid touching the trigger.

Answer

avoid touching the trigger.Avoiding hitting the trigger should be the primary priority while withdrawing and securing a firearm from a trauma victim's pocket.  Even if it is certain the gun is empty of ammunition, it should still be regarded as loaded. To avoid disturbing fingerprints or residue from gun powder, the gun should be carefully removed while using gloves, and it should always be stored in a safe container rather than a paper bag. Never point the barrel of the gun at anyone else while moving it. If the firearm has a safety feature, it must be activated.

Question 5

Reimplantation should ideally be done immediately if a patient with facial fractures also has dentoalveolar damage and their permanent teeth have been lost.

Accepted Answer

30 minutes.

Answer

Reimplantation should ideally be done within 30 minutes if a patient with facial fractures also has dentoalveolar trauma and their permanent teeth have been lost, as saving the tooth after two hours or if the root has dried out is frequently not viable.  Teeth should be kept in a moist setting, such as in NS, if they cannot be promptly reimplanted.  Because of their high failure rate and the potential for permanent teeth beneath them to be harmed, pediatric deciduous teeth are typically not reimplanted.
