Giving away valued possessions

Engaging in high-risk behaviors

Talkative, with pressured speech

Guilt, decreased self-esteem

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is A

Explanation

A. Dopamine at low doses primarily increases renal perfusion, which can lead to improved urine output. An increase in urine output is a key indicator that the medication is effectively improving kidney function and blood flow. This is the most direct way to assess its effectiveness.
B. A decrease in blood pressure is not an expected effect of low-dose dopamine, which should actually help improve perfusion and raise blood pressure.
C. An increase in heart rate is more likely with higher doses of dopamine and is not an optimal indicator of the drug's effectiveness for acute heart failure.
D. Client alertness is important but does not directly reflect the primary effects of dopamine on renal perfusion and cardiac output in acute heart failure.

A. count the number of large squares in the R-R interval and divide by 30C B. print a 1-minute ECG strip and count the number of ORS complexes, C. count the number of QRS complexes in 6 seconds and multiply by 10. D. calculate the number of small squares between one QRS complex and the next one and divide by 1500.

Correct Answer is C

Explanation

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.
