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:
- Four types of reflexes: 1-stretch reflex, 2-Golgi tendon reflex, 3-crossed extensor reflex and 4-withdrawal reflex.
- Components of the deep tendon reflex: intact sensory nerve, functional synapse in the cord, intact motor nerve fiber, neurotransmitter junction and muscle.
- Aging process affects the brain because brain shrinks with increasing age
- Good health practices can mitigate health problems associated with the brain: avoid foods high in fat and cholesterol, regular physical exercise, avoid smoking, avoid excessive alcohol intake, etc.
Explanation:
The four types of reflexes that are integrated within the spinal cord include 1-stretch reflex (that leads to the contraction of a muscle in response to passive stretching), 2-crossed extensor reflex (a contralateral compensatory reflex), 3-Golgi tendon reflex, and 4-withdrawal reflex (a spinal reflex that protects the body from damaging stimuli). The deep tendon reflex (DTR) is a reflex that elicits involuntary contraction of the muscle, which is a fundamental aspect of a neurological evaluation. The five components of a DTR include intact sensory nerve (afferent that carries sensory information), intact motor nerve fiber (efferent that sends signals from the brain), functional synapse in the cord, neurotransmitter junction and muscle. Accelerated aging can lead to brain atrophy and brain shrinkage (especially in the frontal cortex). Healthy lifestyle strategies can minimize changes in an aging brain. Aging leads to increased stiffness of the large arteries, thereby increasing the risks of stroke. Low-fat foods and high-fiber foods (e.g., fresh fruit and vegetables) promote a healthy vascular system and help to maintain brain health. In this regard, it is also imperative to avoid high-sodium foods. Moreover, it has been shown seafood consumption may also reduce the risk of stroke. Other tips include: energy restriction (calory restriction) reduces oxidative damage, antioxidant supplements help to improve cognitive functions, avoid alcohol intake reduces the risks of cardiovascular diseases and dementia.
Answer:
The right and left cerebral hemispheres
Explanation:
Cerebrum is a term often used to describe the entire brain & fissure or groove that separates the two hemispheres is called the great longitudinal fissure.
A 9-year-old has suffered a severe anaphylactic reaction and dies. The nurse is providing support for the grieving parents. "How can I help you get through this?" would best help them cope.
<h3>How do you cope with the loss of a loved one?</h3>
- Permit yourself to experience sadness for your loss.
- Grieving does not always go through stages.
- Prepare yourself for unwelcome reminders.
- Keeping in mind a loved one as you go.
- Count on your loved ones and pals.
- Individuals that are "great listeners" deserve your attention.
- Join a group that offers grief support.
- Speak with a grief specialist.
Hence, A 9-year-old boy experiences a fatal anaphylactic reaction and passes away. The nurse is offering the parents' who are in mourning assistance. The nicest thing to say to them would be, "How can I help you get through this?"
