Evidence has demonstrated that we can do a great deaI to prevent and minimalize the occurence of CTE (Concussion Tramatic Encephalophy), damage due to repetitive head injuries. Which of the answers below are true:

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.

To calculate the dose of amoxicillin for the toddler:

Step 1: Convert the toddler's weight from pounds to kilograms.

33 lb ÷ 2.2 (lb to kg conversion factor) = approximately 15 kg

Step 2: Calculate the total daily dose of amoxicillin.

Dose = 30 mg/kg/day × 15 kg = 450 mg/day

Step 3: Divide the total daily dose into equal doses every 12 hours.

450 mg/day ÷ 2 doses = 225 mg/dose

Step 4: Calculate the amount of amoxicillin suspension needed for each dose.

The available concentration is 200 mg/5 mL, so for 225 mg, you would use the proportion:

225 mg : 200 mg = x mL : 5 mL

Cross-multiplying: x = (225 mg × 5 mL) / 200 mg ≈ 5.625 mL

Therefore, the nurse should administer approximately 5.625 mL of amoxicillin suspension for each dose.
