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. Apply cool sterile soaks to the child's head.
Explanation: Applying cool sterile soaks to the child's head would not directly address periorbital edema. Nephrotic syndrome is a kidney disorder that results in proteinuria (loss of protein in urine), leading to fluid accumulation and edema. Cooling the head would not have a significant impact on reducing periorbital edema caused by nephrotic syndrome.
B. Apply warm compresses.
Explanation: Correct Choice. Applying warm compresses can help increase blood circulation and promote the reabsorption of excess fluid causing periorbital edema. Warmth can dilate blood vessels and improve the movement of fluids, potentially alleviating the edema.
C. Encourage the child to eat low protein foods.
Explanation: While dietary modifications might be part of managing nephrotic syndrome, specifically encouraging low protein foods may not directly address periorbital edema. The primary treatment for nephrotic syndrome involves medications to control proteinuria and manage fluid balance.
D. Elevate the head of the bed.
Explanation: Elevating the head of the bed is more commonly used to manage conditions like heart failure or obstructive sleep apnea. It might have some impact on overall fluid distribution, but it's not the most effective measure for reducing periorbital edema caused by nephrotic syndrome.
Correct Answer is A
Explanation
A) Heat intolerance.
Explanation: This statement is true. Heat intolerance is a common symptom of hyperthyroidism, including Graves' disease. People with hyperthyroidism often have an overactive thyroid gland that produces an excessive amount of thyroid hormones. This can lead to an increased metabolic rate, which in turn makes them sensitive to heat. They may feel excessively warm, sweat more than usual, and have difficulty tolerating hot weather.
B) Weight gain.
Explanation: This statement is false. Weight gain is not a typical finding in Graves' disease or hyperthyroidism. In fact, one of the hallmark symptoms of hyperthyroidism is unexplained weight loss despite increased appetite. The elevated levels of thyroid hormones cause an increase in metabolism, leading to weight loss.
C) Bradycardia.
Explanation: This statement is false. Bradycardia refers to an abnormally slow heart rate, typically below 60 beats per minute. In hyperthyroidism, the heart rate is often elevated rather than slowed down. The excessive thyroid hormones can lead to an increased heart rate (tachycardia) and palpitations. It's important to note that if the question were about hypothyroidism (underactive thyroid), bradycardia might be more relevant.
D) Lethargy.
Explanation: This statement is false. Lethargy, or a state of extreme tiredness and lack of energy, is more commonly associated with hypothyroidism (underactive thyroid) rather than hyperthyroidism. Hyperthyroidism usually leads to symptoms of increased energy, restlessness, and hyperactivity due to the elevated metabolic rate caused by excess thyroid hormones.
