  a. Carefully place the drop on the cornea.
  b. Wipe the eye with a tissue after placing the eyedrop.
  c. Hold the eyedropper about 1 to 2 cm above the eye.
  d. Instruct the patient to squeeze the eye shut after instillation.

Answer to Question 1

C
Holding the eyedropper approximately 1 to 2 cm ( to inch) above the conjunctival sac of the eye prevents accidental contact of the eyedropper with the eye and reduces risk for injury and transfer of microorganisms to the dropper. The cornea is very sensitive. If drops were instilled onto the cornea, this would stimulate the blink reflex. The tissue should be placed just below the lower eyelid so medication that escapes the eye is absorbed. Wiping the eye removes too much of the medication. Squinting or squeezing the eyelids after instillation forces the medication from the conjunctival sac.

Answer to Question 2

C
In the patient with COPD, high levels of oxygen can extinguish the stimulus to breathe. In the individual with healthy lungs, the chemoreceptors are sensitive to small changes in carbon dioxide levels and effectively regulate ventilation. In patients with COPD who retain carbon dioxide, the chemoreceptors are not sensitive to small changes in carbon dioxide and regulate ventilation poorly. In these patients, it is the change in the oxygen level that stimulates changes in ventilation. Patients with COPD are at risk of retaining carbon dioxide and developing carbon dioxide narcosis induced by administration of high levels of oxygen. Uncontrolled oxygen administration may cause acute hypoventilation and carbon dioxide retention with dire consequences. Arterial oxygen saturation levels should be at 88 to 92 and no higher. Some patients with COPD have normal oxygen levels during the day but oxygen desaturation during sleep.

It is believed that the Incas used anesthesia. Evidence supports the theory that shamans chewed cocoa leaves and drilled holes into the heads of patients (letting evil spirits escape), spitting into the wounds they made. The mixture of cocaine, saliva, and resin numbed the site enough to allow hours of drilling.

The cure for trichomoniasis is easy as long as the patient does not drink alcoholic beverages for 24 hours. Just a single dose of medication is needed to rid the body of the disease. However, without proper precautions, an individual may contract the disease repeatedly. In fact, most people develop trichomoniasis again within three months of their last treatment.

Did you know?

The use of salicylates dates back 2,500 years to Hippocrates’s recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.

Stevens-Johnson syndrome and Toxic Epidermal Necrolysis syndrome are life-threatening reactions that can result in death. Complications include permanent blindness, dry-eye syndrome, lung damage, photophobia, asthma, chronic obstructive pulmonary disease, permanent loss of nail beds, scarring of mucous membranes, arthritis, and chronic fatigue syndrome. Many patients' pores scar shut, causing them to retain heat.

Thyroid conditions cause a higher risk of fibromyalgia and chronic fatigue syndrome.
