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 ["5.625"]
Explanation
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.
Correct Answer is D
Explanation
A. Using a suppository for bowel movement is a common approach for managing bowel function in people with paralysis and is appropriate.
B. Carrying a water bottle to stay hydrated is important, especially since individuals with paralysis may be at increased risk of urinary tract infections. Adequate hydration is beneficial.
C. Doing wheelchair exercises while watching TV is a proactive way to maintain muscle tone and overall health, which is crucial for individuals with paralysis.
D. "I only need to catheterize myself twice every day!"
Explanation: In the context of spina bifida and paralysis from the waist down, catheterization is often required for bladder management. Individuals with this condition often experience urinary retention and require intermittent catheterization to empty their bladder. However, "twice every day" is not usually sufficient for someone with paraplegia. Adequate catheterization frequency is crucial to prevent urinary retention, infections, and other complications.
