Which three symptoms are characteristic of Cushing triad associated with increased ICP?
Bradycardia, hypertension, and widening pulse pressure
Widening pulse pressure, headache, and seizure
Hypertension, tachycardia, and headache
Hypotension, tachycardia, and narrowing pulse pressure
The Correct Answer is A
A. Bradycardia, hypertension, and widening pulse pressure
This combination of symptoms is characteristic of Cushing's triad. Bradycardia (slow heart rate), hypertension (elevated blood pressure), and widening pulse pressure (difference between systolic and diastolic blood pressure) are indicative of increased ICP, specifically resulting in the compression of brain structures that regulate vital functions.
B. Widening pulse pressure, headache, and seizure
While headache and seizure may occur in patients with increased ICP, widening pulse pressure alone is not sufficient to meet the criteria of Cushing's triad. The presence of bradycardia and hypertension, along with widening pulse pressure, is more indicative of Cushing's triad.
C. Hypertension, tachycardia, and headache
Hypertension and headache may occur in patients with increased ICP, but the absence of bradycardia and widening pulse pressure makes this option less characteristic of Cushing's triad.
D. Hypotension, tachycardia, and narrowing pulse pressure
Hypotension (low blood pressure) and narrowing pulse pressure are not typically associated with Cushing's triad. Tachycardia (rapid heart rate) may occur in response to increased ICP, but it is usually accompanied by bradycardia rather than hypotension.

Correct Answer is A
Explanation
A. Lie flat:
This option involves instructing the patient to lie flat on their back without elevating their head. Lying flat helps to maintain consistent pressure in the spinal canal, reducing the likelihood of CSF leakage from the puncture site. This position is commonly recommended after a lumbar puncture to prevent or minimize the occurrence of post-lumbar puncture headaches (PLPH).
B. Lie on left side:
This option involves instructing the patient to lie on their left side. While lying on the left side may provide some relief by reducing pressure on the lumbar puncture site, it is not typically recommended immediately after the procedure to prevent PLPH. Lying flat is generally preferred to minimize changes in CSF pressure and reduce the risk of headache.
C. Stay in semi-Fowler position:
The semi-Fowler position involves elevating the head of the bed at a 30-45 degree angle. This position is not typically recommended immediately after a lumbar puncture because it may increase CSF leakage and pressure changes, potentially exacerbating the risk of developing a headache.
D. Ambulate in the room with assistance:
Ambulating shortly after a lumbar puncture is not typically recommended as it may increase the risk of developing a headache. Movement and changes in posture can exacerbate CSF leakage and pressure changes at the puncture site, leading to the development of post-lumbar puncture headaches.
Correct Answer is C
Explanation
A. Diarrhea:
Diarrhea is not a common side effect of phenytoin. While gastrointestinal disturbances such as nausea, vomiting, and constipation may occur, diarrhea is less common. Therefore, it is not a primary adverse effect that the nurse should instruct the client to monitor and report.
B. Wrist pain:
Wrist pain is not a common side effect of phenytoin. Side effects related to musculoskeletal issues such as joint pain, muscle weakness, or muscle twitching can occur, but wrist pain specifically is not commonly associated with phenytoin use. Therefore, it is not a primary adverse effect that the nurse should instruct the client to monitor and report.
C. Skin rash:
Skin rash is a potential adverse effect of phenytoin that should be monitored and reported. Phenytoin can cause various skin reactions, including a mild rash or more severe reactions such as Stevens-Johnson syndrome or toxic epidermal necrolysis. Therefore, the nurse should instruct the client to promptly report any signs of skin rash or other skin changes.
D. Metallic taste:
Metallic taste is a common side effect of phenytoin. While it is not usually a serious adverse effect, it can be bothersome for some individuals. Therefore, the nurse should instruct the client to monitor for this side effect and report it if it occurs persistently or becomes bothersome.
