Answer:

a. Absent p wave is present in atrial fibrillation.

b. Abnormally long QRS complex is present in right or left bundle branch block.

c. Abnormally long PR interval is present in first degree heart block.

d. extra QRS complexes are present in abnormal pacemaker or abnormal conducted beat.

Explanation:

By reading the ECGS we can fine a number of abnormalities by simply locating problems in P, QRS, T waves, PR intervals and ST segments.

Absent P wave in an ECG represents Atrial fibrillation or sinoatrial arrest. Atrial fibrillation is an abnormal heart rhythm  also know as arrhythmia characterized by rapid and irregular beating of the atrial chambers of the heart.

Abnormally long QRS complex represents Right or left bundle branch block, hyperkalemia, drug induced or abnormal ventricular rhythm.

Abnormally long PR interval represents heart block. The PR interval reflects impulse conduction from the atria to the ventricles is normal. A long PR interval  indicates a slowing of conduction between the atria and ventricles, usually due to slow conduction through the atrioventricular node (AV node). This is known as first degree heart block.

Extra QRS complexes represents abnormal pacemaker conductivity.

Answer: The question is not arranged well,below is the correct arrangement;

You are presented with a stack of ECGs on your first day of your cardiology rotation and are given a instruction: "Read them." As you progress through the pile, you note the following abnormalities. Explain from where in the heart or cardiac conduction system each abnormality might have come;

a. Absent p waves

a. Abnormally long QRS complex

b. Abnormally long P-R interval

c. Extra QRS complexes.

Explanation: This indicated a problem in the sinoatrial node, as it is not generating the depolarization that spreads through the atria to lead to the P wave.

An ECG ( electrocardiogram) is a test that measures the electrical activity of the heart to show whether the heart is working normally or not.

GenaCL600 [577]

Answer:

Sumaya's dosage for the day is 90mg

Explanation:

Given

PO=9mg/kg --- daily

Weight = 10kg

Required

The daily dosage

To do this, we simply multiply Sumaya's weight and the dose of PO

So, we have:

Dosage = PO * Weight

Dosage = 9mg/kg * 10kg

Dosage = 90mg

gladu [14]

Answer:

The correct answer is D.

Explanation:

Sperm is produced in the seminiferous tubules of the testes, then it travels through the straight tubules and the rete testis and arrives at the <u>epididymis to mature and to be stored.</u>

When ejaculation occurs, sperm leaves the epididymis through the vas deferens and arrives to the ejaculatory duct. Then ejaculatory duct passes through the prostate to merge witch the urethra and finally sperm leaves the body.

stepan [7]

The altered diagnostic test that is consistent with the development of edema in a client with liver disease would be an elevated serum albumin level.

What is Edema?

Edema is a condition in which fluid builds up in the body's tissues, causing them to swell. It is most commonly caused by poor circulation, heart failure, kidney failure, or liver failure, but can also be caused by an allergy or infection.

What is Albumin?

Albumin is a type of a protein found in the blood. It helps to regulate the amount of fluid in the body and transports vitamins and hormones throughout the body. Albumin is produced in the liver and helps maintain a healthy balance of fluids and electrolytes. It is also important for wound healing and helps to keep the body's immune system functioning properly.

What do you mean by Liver disease?

Liver disease is a broad term used to describe any condition that affects the liver. It can range from mild and reversible conditions to more serious, long-term conditions. Liver diseases can be caused by a variety of factors such as viral infections, alcohol abuse, exposure to certain toxins, or autoimmune conditions. Symptoms of liver disease can include jaundice, fatigue, weight loss, nausea, abdominal pain, and itching.
