What are the options for this question?
Pulmonary valve stenosis is a narrowing of the valve located between the lower right heart chamber (right ventricle) and the lung arteries (pulmonary arteries).
The primary step is to train the health care professionals about the injection techniques and to determine if the child is of the appropriate age to receive the injection.
Good injection practice deals with selecting the appropriate site for administration. The route of administration of injection is mostly intramuscular in a child. The drug is delivered to the vascular muscle tissue and is rapidly absorbed into the circulation of the child. Diabetes insipidus is a disorder that leads to imbalanced fluid in the body. This causes frequent urination, a condition referred to as polyuria. Vasopressin is the anti-diuretic hormone, the lack of which causes diabetes insipidus. Administration of vasopressin externally helps the kidneys to retain water and prevent dehydration.

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.
