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 D
Explanation
A) Kidneys are very small and irregular.
Explanation: This statement is not the primary reason for instructing caregivers about preventing kidney injury in babies or children under 2 years old. While it is true that infant and toddler kidneys are relatively smaller and have a slightly different shape compared to adult kidneys, the main concern for kidney injury prevention in this age group is related to other factors.
B) The occurrence of Hirsutism.
Explanation: Hirsutism refers to excessive hair growth, typically in a male pattern, in women and children. It is not directly related to kidney injury prevention in babies or children under 2 years old. Hirsutism is usually caused by hormonal imbalances and is not a primary consideration when instructing caregivers about preventing kidney injury.
C) Diaper rashes.
Explanation: Diaper rashes are skin irritations that occur in the diaper area of infants and young children. While diaper rashes can be uncomfortable and require proper care, they are not a major concern when instructing caregivers about preventing kidney injury. Diaper rashes are typically a result of prolonged exposure to moisture and can be managed with good hygiene practices and appropriate diaper-changing routines.
D) Children under two years old are more vulnerable to kidney trauma from compression force to abdomen.
Explanation: This statement is true and is the main reason for instructing caregivers about preventing kidney injury in babies or children under 2 years old. Children in this age group have relatively larger abdomens and less developed abdominal muscles, which makes their kidneys more susceptible to injury from compression forces to the abdomen. This is why caregivers are advised to handle young children carefully, avoid rough play, and ensure that they are securely fastened in car seats and other safety devices to prevent potential kidney trauma.
Correct Answer is A
Explanation
A. You do not need to lose consciousness to suffer a concussion.
This statement is true. Concussion is a type of traumatic brain injury (TBI) that can occur without loss of consciousness. Many concussions happen without the person losing consciousness at all.
B. You will suffer permanent brain damage.
This statement is not necessarily true. While some concussions can lead to lasting effects, not all cases result in permanent brain damage. The severity and long-term effects of a concussion can vary widely.
C. We encourage fluids after a concussion.
This statement is true. Adequate hydration is important after a concussion. Staying hydrated can help support the brain's recovery process.
D. Bleeding always occurs with a concussion.
This statement is not true. Concussion is defined by the disruption of normal brain function due to a blow or jolt to the head or body, and bleeding is not always a necessary component of a concussion. However, more severe head injuries could involve bleeding and would not be classified as just a concussion.
