Answer:
Since this question has multiple subquestions in it, I will give you the answer to them as follows:
1. Which neuron would activate a muscle? They are called multipolar neurons, they are found mostly originating from the CNS itself and they are multipolar because when a neuron stimulates a muscle, one signal from just one terminal is not enough; it requires the stimulation from several neurnal terminals.
2. Which neuron would be found in the retina of the eye? A bipolar neuron. This is because these neurons will fulfill a double function: to activate the muscles of the retina, and also they will convey messages taken by the sense of sight, towards the brain for interpretation and integration.
3. Which neuron is a sensory neuron found in a reflex arc? The answer again is a unipolar neuron. These neurons will not reach the brain itself, but rather the reflex arc site on the spinal cord. Their task is to relay sensations from the site that has been stimulated to the spinal cord and from there to the affected place, with the correct response.
4. Which neuron is never myelinated? Again the answer is the bipolar neurons found connecting the retina and the eyes. The reason is that these neurons are capable of relying fast messages to and from the brain, whereas in myelinated ones, messages go slower due to the myeling sheaths.
5. Which neuron is typically involved in the special senses of sight and smell? Once more the answer is the bipolar neurons that are most commonly found connecting the different organs of these two senses. Since these have such unique capabilities: relying information for integration and sensory and motor responses, their action potentials travel fast, and have a short distance to go.
Answer:
Adenoids
Explanation:
They help the immune system fight off viruses and bacteria. They become less important as we age.
Answer:
- Cardiac output = defined as the amount of blood that comes out with each ventricular contraction in a minute. Normally in a healthy and young person it is 4.5 L / min.
- Heart rate = It is the amount of heartbeats in a minute. Normally it goes between 60 to 100 contractions per minute.
- Stroke Volume = It is the amount of blood ejected from the heart to the aorta and to the pulmonary artery in each contraction.
Answer:
EBP is highly beneficial and integral for nursing practice because it keeps the nurse practitioners updated about current protocols and interventions that are most effective among patients.
The barriers to EBP implementation identified in nursing are many but the most frequent are known to be heavy workload, workforce shortage, lack of access to credible literature i.e. nursing libraries, lack of internet at workplace and lack of continued professional education.
Explanation:
Evidence-base practice (EBP) is vital for advanced nursing practice and holistic care delivery. EBP enables nurse practitioners to determine an effective course of action for holistic care delivery. EBP helps in establishing the correct diagnosis by looking into the clinical problem through evidence-base. The best-suited evidence to patient’s condition is then selected and analyzed. Afterwards, the evidence is applied on clinical practice which is most likely to be effective as indicated in the current nursing literature. EBP is gathered through credible sources such as randomized clinical trials, evidence gathered from case studies, and opinions of clinical experts supported by reports.
Nurse practitioners who are working long-hours faces burnout and fatigue which decreases their work performance and does not allow them to read current nursing literature. Moreover, nursing workforce shortage also increases individual workload among nurses and they did not get the time to make individualized intervention plans for patients.
