The nurse is attempting to determine the ventricular rate and rhythm of a patient's telemetry strip. What should the nurse examine to determine this part of the analysis?

RR Interval

QT interval

PP interval

PR interval

Answer and Explanation

The Correct Answer is A

A. RR Interval:

The RR interval is the time between two consecutive R waves on an electrocardiogram (ECG) strip. It is primarily used to determine the ventricular rate and rhythm of the heart. A regular RR interval suggests a regular heart rhythm, while irregular intervals may indicate arrhythmias or other cardiac abnormalities. Calculating the RR interval can help determine the heart rate (ventricular rate) by dividing 60 seconds by the RR interval in seconds (e.g., if the RR interval is 0.8 seconds, the heart rate would be approximately 75 beats per minute).

B. QT Interval:

The QT interval represents the time from the start of the Q wave to the end of the T wave on an ECG. It reflects the time it takes for the ventricles to depolarize and repolarize. Prolongation or shortening of the QT interval can indicate certain cardiac conditions or medication effects, including an increased risk of arrhythmias such as torsades de pointes. However, it is not directly used to determine ventricular rate and rhythm as the RR interval is.

C. PP Interval:

The PP interval is the time between two consecutive P waves on an ECG strip. It is primarily used to assess the atrial rate and rhythm. Regular PP intervals indicate a regular atrial rhythm, while irregular intervals may suggest atrial arrhythmias such as atrial fibrillation or atrial flutter. The PP interval is not directly used to determine ventricular rate and rhythm.

D. PR Interval:

The PR interval is the time from the start of the P wave to the start of the QRS complex on an ECG strip. It represents the time it takes for the electrical impulse to travel from the atria to the ventricles. A normal PR interval is typically between 0.12 to 0.20 seconds. Prolongation or shortening of the PR interval can indicate certain cardiac conduction abnormalities.

Correct Answer is ["1"]

Explanation

If the nurse needs to administer vancomycin 500 mg PO daily divided into four equal doses, and the available capsules are vancomycin 125 mg each, the nurse would administer:

500 mg total daily dose ÷ 4 doses = 125 mg per dose

Since each capsule contains 125 mg of vancomycin, the nurse would administer 1 capsule with each dose.

A. Take the medication with milk to increase absorption. B. Take the medication on an empty stomach C. Eat foods high in fiber while on this medication. D. Report stools that are dark in color immediately. E. Eating citrus fruit and juices are recommended with meals.

Correct Answer is ["B","C","D","E"]

Explanation

A. Take the medication with milk to increase absorption:

This statement is incorrect. Taking ferrous sulfate with milk or dairy products is not recommended as they can decrease iron absorption. It's advisable to take iron supplements with water or juice, preferably on an empty stomach or with a small amount of food.

B. Take the medication on an empty stomach:

This statement is partially correct. While taking ferrous sulfate on an empty stomach can enhance absorption, some individuals may experience gastrointestinal discomfort or irritation. Therefore, it's often recommended to take iron supplements with a small amount of food to minimize potential side effects.

C. Eat foods high in fiber while on this medication:

This statement is generally correct. Consuming foods high in fiber can help prevent constipation, which is a common side effect of iron supplements. Including fiber-rich foods in the diet, such as fruits, vegetables, whole grains, and legumes, can promote regular bowel movements.

D. Report stools that are dark in color immediately:

This statement is correct. Dark or black stools can indicate the presence of digested blood, which may occur due to iron supplementation. It's important to report such changes to the healthcare provider promptly for further evaluation.

E. Eating citrus fruit and juices are recommended with meals:

This statement is correct. Citrus fruits and juices, such as oranges, grapefruits, and lemon juice, contain vitamin C, which can enhance iron absorption. Consuming vitamin C-rich foods or drinks along with iron supplements can help improve iron uptake by the body.
