Cushings Triad is an ominous sign including the following:
Elevated blood glucose is remarkable with Cushings triad
Cushings Triad includes a positive Macawens sign
Cushings triad includes tachycardia, seizures and rapid respirations
Bradycardia, irregular respirations and a widening pulse pressure.
The Correct Answer is D
A. Elevated blood glucose is remarkable with Cushing's Triad:
Elevated blood glucose is not one of the components of Cushing's Triad. The triad focuses on cardiovascular and respiratory changes associated with increased intracranial pressure, not blood glucose levels.
B. Cushing's Triad includes a positive Macawen's sign:
Macawen's sign is not part of Cushing's Triad. Cushing's Triad is specifically related to the physiological responses seen in response to increased intracranial pressure and is not associated with Macawen's sign.
C. Cushing's Triad includes tachycardia, seizures and rapid respirations:
This option is not accurate. Cushing's Triad involves bradycardia (slow heart rate), irregular respirations, and a widening pulse pressure. Tachycardia (rapid heart rate) and seizures are not part of Cushing's Triad but might be indicative of other medical conditions or complications.
D. Bradycardia, irregular respirations and a widening pulse pressure.
Explanation: Cushing's Triad is a set of three clinical signs that are indicative of increased intracranial pressure (ICP) and are considered ominous as they suggest serious brain injury or pathology. The triad consists of:
Bradycardia: This refers to a slow heart rate. As intracranial pressure increases, it can lead to a decreased heart rate due to pressure on the brainstem, which is involved in regulating heart rate.
Irregular Respirations: Increased ICP can affect the brainstem's control over breathing, leading to irregular patterns of breathing, often known as Cheyne-Stokes respiration. This is characterized by periods of rapid breathing followed by apnea (temporary cessation of breathing).
Widening Pulse Pressure: Pulse pressure is the difference between systolic and diastolic blood pressure. An increase in ICP can cause an increase in systolic blood pressure and a decrease in diastolic blood pressure, leading to a widening pulse pressure.

Correct Answer is B
Explanation
A. Dizziness is always a sign of a concussion.
This statement is incorrect. While dizziness can be a symptom of a concussion, it is not always indicative of a concussion. There can be various causes of dizziness, and it is essential to consider other symptoms as well when assessing for a concussion.
B. Bike Helmet Safety
Explanation:
The correct answer to include as part of concussion/head injury prevention teaching to children and parents is "Bike helmet safety." This is because wearing a helmet while riding a bike or participating in other activities that involve head injury risks is crucial to prevent head injuries and concussions. Helmets provide protection to the head by absorbing impact energy and reducing the risk of skull fractures or traumatic brain injuries.
C. Normal fluid intake.
While staying hydrated is important for overall health, it is not directly related to concussion or head injury prevention teaching. This choice is unrelated to the topic.
D. Signs of autism.
Signs of autism are unrelated to concussion or head injury prevention teaching. This choice is not relevant to the topic at hand.
Correct Answer is A
Explanation
A) Vaccinations to prevent pneumococcal and Haemophilus influenzae type B meningitis are available.
Explanation: This statement is true. Vaccinations to prevent certain types of bacterial meningitis are available. Pneumococcal and Haemophilus influenzae type B (Hib) vaccines are included in routine childhood immunization schedules to protect against the bacteria that can cause meningitis and other serious infections. These vaccines have significantly reduced the incidence of bacterial meningitis in infants and children.
B) Often a genetic predisposition to meningitis is found.
Explanation: This statement is generally false. While there may be some genetic factors that influence susceptibility to infections, including meningitis, genetic predisposition is not a primary consideration when discussing the risk of meningitis. Meningitis is more commonly caused by bacterial or viral infections, and genetic predisposition is not a significant factor in its occurrence.
C) Meningitis rarely occurs during infancy.
Explanation: This statement is false. Meningitis can occur in infants, including newborns. In fact, infants are one of the age groups at higher risk for meningitis due to their underdeveloped immune systems and susceptibility to infections. Bacterial meningitis, in particular, can be severe and life-threatening in infants.
D) Vaccination to prevent all types of meningitis is now available.
Explanation: This statement is not entirely accurate. While vaccinations are available to prevent certain types of bacterial meningitis (such as pneumococcal and Hib meningitis), there is no single vaccine that can prevent all types of meningitis. Meningitis can be caused by various bacteria, viruses, and other pathogens, and the vaccines target specific ones. It's important for caregivers to ensure that their infants receive recommended vaccines to protect against the most common causes of meningitis.
