a technician is filling a medication for a 4 year old child weighing 45 lbs. the average adult dose is 250 mg. how much medication should the child receive?
The amount of medication that a child should receive will depend on several factors, including their weight, age, and the specific medication that they are taking.
In general, medication doses for children are typically calculated based on their weight rather than their age or adult doses. This is because children's bodies may metabolize medications differently than adults, and their weight may be a better indicator of their overall size and health.
To determine the appropriate dose of medication for a child, it is important to follow the dosing instructions provided by the child's healthcare provider or the medication's manufacturer. These instructions will typically take into account the child's weight, age, and other factors to determine the correct dose.

a patient in a barbiturate coma for increased intracranial pressure (icp) has audible gurgling through the endotracheal tube. what should the nurse do first before suctioning this patient?
The nurse should do first before suctioning this patient who is in coma for increased intracranial pressure is Administer 100% oxygen.
Intracranial strain (ICP) is the tension applied by liquids like cerebrospinal liquid (CSF) inside the skull and on the mind tissue. The ICP, which is measured in millimeters of mercury (mmHg), typically ranges from 7 to 15 mmHg for an adult lying down. The body uses a variety of mechanisms to keep the ICP stable. Normal adults' CSF pressures fluctuate by about 1 mmHg due to shifts in CSF production and absorption.
Changes in ICP are ascribed to volume changes in at least one of the constituents contained in the skull. The valsalva maneuver, communication with the vasculature (the venous and arterial systems), and sudden changes in intrathoracic pressure during coughing (which is induced by contraction of the diaphragm and abdominal wall muscles, the latter of which also increases intra-abdominal pressure) have been shown to influence CSF pressure.

The position should the nurse prepare to position the client after an automobile crash is On bed rest in a semi-Fowler's position, option B.
The presence of blood in the anterior chamber is known as a hyphema. When enough force is applied to break the eye's blood vessels' integrity, it occurs. It tends to be brought about by direct injury, like entering injury from a BB pellet, or by implication, for example, from striking the temple on a guiding wheel during a mishap. The client is treated by bed rest in a semi-Fowler's situation to help gravity in getting the hyphema far from the optical focus of the cornea.
Fowler's position works with the unwinding of strain of the stomach muscles, taking into account worked on relaxing. The Fowler position relieves gravity-induced chest compression in immobile patients and infants. Fowler's position is used in postpartum women to improve uterine drainage and in infants when signs of respiratory distress are present. It also increases comfort during eating and other activities.

if a person has a blood-calcium (ca2 ) level of 8 mg/100 ml of blood, what mechanisms does the body use tomaintain blood-calcium homeostasis
The body employs several mechanisms to maintain blood-calcium homeostasis when the blood-calcium (Ca2+) level is 8 mg/100 ml.
One key mechanism is the action of parathyroid hormone (PTH), which is released by the parathyroid glands when blood calcium levels drop. PTH stimulates the release of calcium from bones into the bloodstream and enhances the reabsorption of calcium by the kidneys, reducing urinary calcium excretion. PTH also stimulates the production of activated vitamin D, which promotes calcium absorption from the intestines.
Additionally, calcitonin, released by the thyroid gland, can help lower blood calcium levels by inhibiting bone breakdown and promoting calcium excretion by the kidneys. These regulatory mechanisms work together to maintain blood-calcium levels within a narrow range, ensuring proper physiological functioning.
