Q

A patient with a head injury has admission vital signs of blood pressure 128/68, pulse 110, and respirations 26. Which of these vital signs, if taken 1 hour after admission, will be of most concern to the nurse?

a. Blood pressure 156/60, pulse 55, respirations 12
b. Blood pressure 130/72, pulse 90, respirations 32
c. Blood pressure 148/78, pulse 112, respirations 28
d. Blood pressure 110/70, pulse 120, respirations 30

A

ANS: A

Systolic hypertension with widening pulse pressure, bradycardia, and respiratory changes represent Cushing’s triad and indicate that the intracranial pressure (ICP) has increased, and brain herniation may be imminent unless immediate action is taken to reduce ICP. The other vital signs may indicate the need for changes in treatment, but they are not indicative of an immediately life-threatening process.

Q

A 20-yr-old male patient is admitted with a head injury after a collision while playing football. After noting that the patient has developed clear nasal drainage, which action should the nurse take?

a. Have the patient gently blow the nose.

b. Check the drainage for glucose content.

c. Teach the patient that rhinorrhea is expected after a head injury.

d. Obtain a specimen of the fluid to send for culture and sensitivity.

A

Answer: b. Check the drainage for glucose content.

Rationale: Clear nasal drainage in a patient with a head injury suggests a dural tear and cerebrospinal fluid (CSF) leakage. If the drainage is CSF, it will test positive for glucose. Fluid leaking from the nose will have normal nasal flora, so culture and sensitivity will not be useful. Blowing the nose is avoided to prevent CSF leakage.

Q

The client diagnosed with a mild concussion is being discharged from the emergency department. Which discharge instruction should the nurse teach the client’s significant other?

  1. Awaken the client every two (2) hours.
  2. Monitor for increased intracranial pressure.
  3. Observe frequently for hypervigilance.
  4. Offer the client food every three (3) to four (4) hours.
A
  1. Awakening the client every two (2) hours allows the identification of headache, dizziness, lethargy, irritability, and anxiety—all signs of postconcussion syndrome—that would warrant the significant other’s taking the client back to the emergency department.
