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) Document intake and output:
Documenting intake and output is an important nursing task, but it is not the top priority in a suspected case of bacterial meningitis. Timely administration of antibiotics to treat the infection takes precedence over documentation of intake and output.
B) Administer antibiotics when available.
Explanation:
Bacterial meningitis is a serious and potentially life-threatening infection of the membranes covering the brain and spinal cord. Rapid administration of antibiotics is crucial to effectively treat the infection and prevent its spread. Delay in antibiotic administration can lead to worsening symptoms and complications. Therefore, getting the appropriate antibiotics to the child as soon as they are available is the nurse's priority.
C) Reduce environmental stimuli:
Reducing environmental stimuli can be helpful in managing symptoms and providing comfort to the child with meningitis, but it is not the priority action. The immediate concern in a suspected case of bacterial meningitis is to treat the infection.
D) Maintain seizure precaution:
While maintaining seizure precautions is important, especially if the child has a history of seizures, it is not the top priority in a suspected case of bacterial meningitis. Administering antibiotics to treat the infection and prevent its progression is the primary concern.
Correct Answer is A
Explanation
A. Levothyroxine
Correct Answer: Levothyroxine should be administered before breakfast.
Explanation: Levothyroxine is a synthetic thyroid hormone used to treat hypothyroidism. It needs to be taken on an empty stomach, at least 30 minutes before eating, to ensure proper absorption. Food can interfere with its absorption, especially foods containing calcium, iron, and fiber.
B. Digoxin
Incorrect Explanation: Digoxin does not need to be administered before breakfast.
Explanation: Digoxin is a medication used to treat heart conditions like congestive heart failure and atrial fibrillation. It doesn't have specific instructions regarding administration in relation to meals. It's important to administer digoxin consistently at the same time every day, but it doesn't need to be taken specifically before or after breakfast.
C. Divalproex
Incorrect Explanation: Divalproex does not need to be administered before breakfast.
Explanation: Divalproex is used to treat conditions like epilepsy and bipolar disorder. It can be taken with or without food. While taking it with food might reduce the likelihood of stomach upset, there's no requirement to take it specifically before breakfast.
D. Mycostatin Mouthwash
Incorrect Explanation: Mycostatin mouthwash is not related to breakfast timing.
Explanation: Mycostatin is an antifungal medication used to treat fungal infections in the mouth (oral thrush). Its administration is not linked to meal times. It's typically swished around in the mouth and then swallowed or spit out, depending on the specific instructions provided by the healthcare provider.
