Head Injury & Basilar Skull Fracture: Nursing Case Study
This case study follows an adolescent patient through the diagnosis and management of a basilar skull fracture, acute subdural hematoma, and subsequent bacterial meningitis. Presented in a question-and-answer format with detailed rationales, the paper covers key nursing assessments — including Battle's sign, the Glasgow Coma Scale, and arterial blood gas interpretation — as well as pharmacologic considerations, ICP prevention strategies, ethical and legal issues surrounding patient confidentiality, therapeutic communication with adolescents, staffing delegation, and discharge teaching. The case concludes with a discussion of alcohol-related risk factors for head injury in the adolescent population.

What makes this paper effective
- Each clinical concept is immediately reinforced with a rationale, making the question-and-answer format pedagogically efficient for nursing students reviewing complex pathophysiology.
- The case progresses logically through escalating acuity — from initial fracture assessment to surgical intervention, post-operative complications, and discharge — mirroring real clinical progression.
- Incorrect answer feedback is as instructive as correct answer feedback, clarifying common misconceptions (e.g., why opioids are contraindicated after head trauma, or why packing the nares is harmful).
Key academic technique demonstrated
The paper employs contrast-based reasoning throughout: for every correct answer, at least two or three plausible alternatives are explained and eliminated. This technique, common in clinical education, teaches students to distinguish between superficially similar options by anchoring each decision in underlying pathophysiology (e.g., why PCO₂ of 35 is preferred over 45 in ICP management).
Structure breakdown
The case is divided into seven thematic sections, each introduced with a brief clinical narrative that advances the patient's condition. Within each section, multiple-choice questions probe assessment, intervention, pharmacology, ethics, communication, or delegation. A short concluding narrative ties the educational content to a real-world public health message about alcohol-related adolescent head injuries.
Basilar Skull Fracture: Assessment and Initial Interventions
A basilar skull fracture is a linear skull fracture that extends over the base of the frontal and temporal lobes. This type of fracture can cause damage to nerve pathways, cranial nerves, or vital centers. The patient's vital signs and neurologic status must be monitored frequently.
Question 1: Which assessment technique allows the nurse to assess for Battle's sign?
The correct answer is to observe the area behind the patient's ears. Battle's sign refers to ecchymosis (bruising) behind the ears and is a common manifestation of a basilar skull fracture. Assessing pupillary response to light is an important part of the neurologic exam but does not demonstrate Battle's sign. Periorbital ecchymosis — known as "raccoon eyes" — is a separate but equally common manifestation. Testing the patient's ability to follow directions is also part of the neurologic assessment but does not demonstrate Battle's sign.
Other manifestations of a basilar skull fracture include tinnitus, facial paralysis, hearing difficulty, epistaxis, and cerebrospinal fluid (CSF) leakage from the nose or ears (rhinorrhea).
Question 2: What methods can the nurse use to determine if the drainage is CSF?
The correct answer is to observe for a "halo" around a spot of drainage. When a drop of drainage is placed on a white dressing, CSF will separate from blood and form a halo ring around the blood spot. The nurse may also assess the appearance of the drainage and use a dextrostick to check for glucose, since CSF — unlike normal nasal drainage — contains glucose. However, if CSF is mixed with blood, the glucose test may yield a false positive, because blood also contains glucose. Measuring specific gravity or quantity of the drainage will not confirm whether it is CSF.
Question 3: Which nursing intervention should be initiated to prevent increased ICP?
The correct intervention is to administer a prescribed stool softener as needed (PRN). Activities such as performing a Valsalva maneuver, coughing, and vomiting increase ICP and must be prevented. The head of the bed should be elevated approximately 30 degrees, and neck flexion and extension should be avoided. Applying a hyperthermia blanket is contraindicated, because increased body temperature raises cerebral blood flow. Restraints should not be used, since straining against them can also increase ICP — clients with head injuries are frequently sedated with agents such as propofol (Diprivan) to prevent restlessness. Packing the nares would prevent CSF from draining and could further increase ICP; a sterile drip pad should be used instead.
Question 4: Which medication is best for treating the patient's headache?
The correct choice is acetaminophen (Tylenol). Tylenol is a non-opioid analgesic and will not cause CNS depression. Opioids — including morphine sulfate, oxycodone/aspirin (Percodan), and hydrocodone/acetaminophen (Lortab) — should be avoided following head trauma because they can cause CNS depression and mask symptoms of increasing ICP. If a non-opioid analgesic does not relieve pain, a hydrocodone product may be considered, since CNS depression is less likely with these than with other opioids; however, acetaminophen remains the best first-line choice.
