When using an ECG rhythm strip to quickly estimate the ventricular rate for a client, the nurse should:

count the number of large squares in the R-R interval and divide by 30C

print a 1-minute ECG strip and count the number of ORS complexes,

count the number of QRS complexes in 6 seconds and multiply by 10.

calculate the number of small squares between one QRS complex and the next one and divide by 1500.

Answer and Explanation

The Correct Answer is C

A.   Counting the number of large squares between R-R intervals and dividing by 30 is not the correct method for estimating the ventricular rate on an ECG strip.
B.   Printing a 1-minute ECG strip and counting the QRS complexes (option B) is accurate but unnecessary for a quick estimation.
C.   The most common and efficient method for estimating the ventricular rate quickly is to count the number of QRS complexes in a 6-second strip (often marked by two dashed lines) and multiply by 10. This gives an estimate of the heart rate per minute.
D.   Counting the number of small squares between QRS complexes and dividing by 1500 is the most accurate method but requires more time and precision than counting QRS complexes in 6 seconds.

Correct Answer is A

Explanation

A. Giving away valued possessions - This is a classic sign of suicidal ideation, as individuals may feel they no longer need their belongings or want to say goodbye to loved ones in a symbolic way.
B. Engaging in high-risk behaviors - While high-risk behaviors can be a sign of depression, they are not necessarily indicative of suicidal thoughts.
C. Talkative, with pressured speech - This could be indicative of a manic episode or high anxiety, but it is not a common sign of suicidal behavior.
D. Guilt, decreased self-esteem - Although guilt and low self-esteem are symptoms of depression, they do not directly indicate suicidal thoughts or behaviors.

A. Prothrombin time, fibrin level and eosinophil count B. Fibrin degradation products, lactic acid and complete blood count C. D-dimer, fibrinogen and fibrin degradation products D. Complete blood count, Complete metabolic panel and prothrombin time

Correct Answer is C

Explanation

A. This test set is incomplete for diagnosing DIC. While PT and fibrinogen are important, the eosinophil count is not a key test for DIC.
B. While fibrin degradation products are useful, lactic acid is not specific for DIC and may indicate other issues. A complete blood count is helpful but not definitive for diagnosing DIC.
C. These are key markers for DIC. An elevated D-dimer indicates clot formation and breakdown, while fibrinogen and fibrin degradation products are used to assess clotting and fibrinolysis, both of which are abnormal in DIC.
D. Complete blood count, complete metabolic panel, and prothrombin time are general tests and can give some clues, but they are not definitive for diagnosing DIC.
