Medicine
1 answer:
Natalka [10]3 years ago
6 0

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.

Pancreatic Enzyme Supplements Are Not Effective for Relieving Abdominal Pain in Patients with Chronic Pancreatitis: Meta-Analysi
Anastaziya [24]

Despite minimal evidence of effectiveness, pancreatic enzyme supplementation is frequently used to relieve pain in people with chronic pancreatitis.

Comparing pancreatic enzyme supplementation to placebo, no improvement in discomfort was seen. The only trial that used enzymes without an enteric coating did indicate a decrease in pain score. In both analyses, there was a significant amount of study heterogeneity. A random model meta-analysis of three studies found no evidence of a difference between the periods of administering pancreatic enzyme supplementation versus placebo in the mean daily pain score (mean difference: 0.09 (1.57-1.39), p=0.91) or average weekly analgesic consumption (mean difference: 0.30 (2.37-1.77), p=0.77). Given their high cost and probable adverse effects, pancreatic enzyme supplements shouldn't be recommended only for treating abdominal pain in people with chronic pancreatitis.

Non-functional organelles can be broken down and essentially recycled by _______ within the cell.
yKpoI14uk [10]

Answer: Option B. "Lysosomes"

Explanation:

Lysosomes are defined as the organelles that act as cell’s recycling center which dispose and digest unwanted carbohydrates, lipids, protein, RNA, and DNA in the cell, one of the major role of lysosomes in the cell.

Lysosome is acidic from inside that contains many enzymes helps in breaking down unwanted molecules. recycling function is initiated by the procsess called autophagy, which allows the cell digests itself due to under stress and when cell undergoes senescence (growth arrest) to preserve energy with the help of enzymes present in it.

In this way the lysosome engulfs external particles and converts it into useful substances like protein, fat and sugar.

Hence, the correct option is B.

watching for the chest to rise as you administer each breath.

If no air is going in you must clear airway –

i. Reposition the head and try your two breaths again.

ii. Finger sweep

iii. Heimlich Maneuver

7. Once airway is open, check for carotid pulse for 5-10 seconds.

to 2 breaths. The heel of the hand is used in the center of the

breastbone to give compressions. Place one hand over the other and

press STRAIGHT down.

9. Recheck pulse for a full 10 seconds after 4th cycle for return of

pulse or breathing. Continue CPR at the rate of 15/2 until help

arrives, the person is revived, or you are physically exhausted and
