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

Answer and Explanation

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 ["10"]

Explanation

To calculate the dose of valproic acid oral solution, the nurse should use the following formula:

Dose (mL) = Ordered dose (mg) / Concentration (mg/mL) x Volume (mL)

Plugging in the values from the question, we get:

Dose (mL) = 500 mg / (250 mg / 5 mL) x 5 mL

Simplifying, we get:

Dose (mL) = 500 mg / 50 mg x 5 mL

Dose (mL) = 10 mL

Therefore, the nurse should administer 10 of valproic acid oral solution to the patient.

A. Fresh fish B. Cheddar cheese C. Cherries D. Chicken

Correct Answer is B

Explanation

A. Fresh fish

Fresh fish does not contain significant amounts of tyramine. Therefore, there is no need to eliminate fresh fish from the client's diet due to its interaction with selegiline.

B. Cheddar cheese

This is the correct answer. Cheddar cheese is a high-tyramine food and should be eliminated from the client's diet when taking MAOIs. Aged cheeses, such as cheddar, contain high levels of tyramine due to the fermentation process, which can increase the risk of a hypertensive crisis when combined with MAOIs.

C. Cherries

Cherries do not contain significant amounts of tyramine. Therefore, there is no need to eliminate cherries from the client's diet due to their interaction with selegiline.

D. Chicken

Chicken does not contain significant amounts of tyramine. Therefore, there is no need to eliminate chicken from the client's diet due to its interaction with selegiline.
