The nurse is teaching the client with a new prescription for ibandronate how to take the medication.
Which instruction provided by the nurse is correct?
“Take 400 mg each day, at the same time each day.”.
“Take 150 mg once a month on the same day of the month.”.
“Take 70 mg once a week on the same day of the week.”.
“Take 3 mg twice daily with food.”.
The Correct Answer is A
This is the recommended dosage for the prevention and treatment of osteoporosis in postmenopausal women.
Choice B is wrong because 70 mg once a week is the dosage for alendronate (Fosamax), not ibandronate.
Choice C is wrong because 400 mg/d is the dosage for etidronate (Didronel), not ibandronate.
Choice D is wrong because ibandronate should be taken on an empty stomach, at least 60 minutes before food or drink.

Correct Answer is A
Explanation
Prednisone is a glucocorticoid that suppresses the production of natural cortisol by the adrenal glands. Taking prednisone on alternate days allows the adrenal glands to recover and produce some cortisol on the days without prednisone.
Choice B is wrong because prednisone does not eliminate adverse side effects, but may cause some such as weight gain, fluid retention, increased blood pressure, increased blood glucose, and increased risk of infection.
Choice C is wrong because there is no evidence of steroid tolerance, which means that higher doses are needed to achieve the same effect.
Choice D is wrong because prednisone does not prolong therapeutic effects, but may decrease them over time due to feedback inhibition of cortisol secretion.
Normal ranges for cortisol are 6 to 23 mcg/dL in the morning and 2 to 11 mcg/dL in the afternoon.
Correct Answer is D
Explanation
Oxygen cannot diffuse rapidly across the membrane to tissues in the eye. This is because diabetic retinopathy is a condition that occurs when high blood sugar levels damage the tiny blood vessels that nourish the retina, the light-sensitive tissue at the back of the eye. As a result, the retina becomes ischemic (lacking oxygen) and tries to grow new blood vessels that are fragile and leaky.
Choice A is wrong because inability of cells in the eye to reproduce is not a cause of diabetic retinopathy.
The retina has a high metabolic rate and needs a constant supply of oxygen and nutrients to function properly.
Choice B is wrong because increase of aqueous humor in the eye is not a cause of diabetic retinopathy.
Aqueous humor is the clear fluid that fills the front part of the eye, not the retina.
An increase of aqueous humor can cause glaucoma, which is a different eye disorder that affects the optic nerve.
Choice C is wrong because decrease of nerve innervations throughout the eye is not a cause of diabetic retinopathy.
Nerve innervations are the connections between nerves and other tissues, such as muscles or glands.
Diabetic retinopathy affects the blood vessels, not the nerves, of the retina.
