A nurse is reinforcing teaching with a newly licensed nurse about coup and contrecoup injuries. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?

A contrecoup injury is not considered a "true" injury, and a coup injury can be more devastating.

The coup injury is the primary focal injury, and the contrecoup injury occurs on the opposite side of the brain.

The coup injury occurs secondary to the contrecoup injury but does not affect blood supply to the brain.

Contrecoup injuries are less severe and easier to heal from over time.

Answer and Explanation

The Correct Answer is B

A. A contrecoup injury is a true injury and can be significant; stating it is not considered "true" is incorrect and indicates a lack of understanding.
B. This statement accurately describes coup and contrecoup injuries, where a coup injury occurs at the site of impact and a contrecoup injury occurs on the opposite side of the brain.
C. This statement is incorrect because a coup injury does not occur secondary to the contrecoup; they can happen simultaneously during trauma.
D. Contrecoup injuries can be just as severe as coup injuries, and the healing process varies; stating they are easier to heal from is misleading and reflects a misunderstanding.

Correct Answer is C

Explanation

A. The recommended sodium intake for individuals with hypertension is typically less than 2,300 mg per day, so a goal of 3,000 mg is too high.
B. For individuals with hypertension, it is recommended to limit alcohol consumption to 1 drink per day for women and 2 drinks per day for men, so 3 drinks is excessive.
C. Planning to have potassium blood levels checked when taking thiazide diuretics is important because these medications can lead to hypokalemia (low potassium levels), making this the correct response.
D. Setting a goal body weight within 25% of ideal body weight is not a standard recommendation; weight management should focus on achieving a healthy weight, rather than a specific percentage of ideal body weight.

A. The QRS intervals are 0.08 second. B. The PR intervals are 0.15 second. C. The ST segment is above the isoelectric line. D. The QT interval is equal to the R to R interval.

Correct Answer is C

Explanation

A. A QRS interval of 0.08 second is within the normal range and does not indicate a myocardial infarction.
B. A PR interval of 0.15 second is normal and not indicative of an acute myocardial infarction.
C. ST-segment elevation above the isoelectric line is a key indicator of an acute myocardial infarction (STEMI), signifying myocardial injury.
