The ECGs QRS complex is the stimulus for atrial diastole.<br> a. True<br> b. False
Natalka [10]

Answer:

The correct answer will be option-A

Explanation:

Electrocardiogram or ECG is the recording and representation of the electrical changes that are taking place during the cardiac cycle.

The QRS complex is preceded by the P wave or atrial systole or atrial depolarization after which the electrical signals are passed on to the AV node.  

As soon as the AV node passes the electrical signals to bundle of His, it is observed in as the QRS interval which represents the atrial diastole and the onset of ventricular depolarization.

Thus, option-true is the correct answer.

In a case-control study of obesity and adult-onset asthma, controls are matched to cases on the basis of race and gender.
Bess [88]

Answer: d. Confounding

Explanation:

In the context of a scientific study such as this one, a confounding factor is one that has influence on both the exposure and event variable(s), which may lead to over- or underestimation of the direct relationship between them (if any).

For instance: In this example, researchers may have had reason to believe that male gender is associated with both higher risk of obesity (the exposure variable) and adult-onset asthma (the event variable). If gender is not taken into account, one may claim that the finding of an association between obesity and asthma is simply an artifact due to the high proportion of male patients (likely to present with both). <em>Controlling</em> for that variable (such as by matching, as in this example) allows researchers to test for this hypothesis.

which would be included in the nursing care for a client at 41 weeks' gestation who is scheduled for a contraction stress test
trapecia [35]

Emptying the client’s bladder would be included in the nursing care for a client at 41 weeks' gestation who is scheduled for a contraction stress test.

The contraction stress test (CST) is a test for pregnant women. It will check your baby for signs of stress during uterine contractions. During the test, your nurse  will give you a hormone that causes your uterus to contract. These contractions are similar to labor contractions, but usually do not initiate labor. When the test starts, the client will require continuous electronic monitoring and will be restricted to bed; contractions are more uncomfortable with a full bladder, so the client is suggested to empty her bladder for some relief.
