A client who has chronic bronchial asthma has had a mast cell stabilizer prescribed.
What drug would the provider prescribe?
Isoetharine.
Aminophylline.
Ipratropium.
Cromolyn.
The Correct Answer is D
Choice A. Isoetharine is a bronchodilator that works by relaxing muscles in the airways to improve breathing. It is not a mast cell stabilizer.
Choice B is wrong because aminophylline is a bronchodilator that relaxes the muscles in the airways and is used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). It is not a mast cell stabilizer.
Choice C is wrong because Ipratropium is an anticholinergic bronchodilator that helps to open up the airways in the lungs. It is used in the treatment of COPD and sometimes asthma, but it is not a mast cell stabilizer.
Choice D. Cromolyn is a mast cell stabilizer that helps prevent the release of substances in the body that cause inflammation and asthma symptoms. It is used for the prevention of asthma attacks and is particularly effective in managing exercise-induced asthma and allergic asthma triggers.

Correct Answer is D
Explanation
Oxygen cannot diffuse rapidly across the membrane to tissues in the eye. Diabetic retinopathy is caused by damage to the blood vessels of the retina, which is the light-sensitive tissue at the back of the eye. This damage can reduce the oxygen supply to the retina and lead to vision problems.
Choice A is wrong because cells in the eye can reproduce normally, but they may not function properly due to high blood sugar levels or lack of oxygen.
Choice B is wrong because diabetic retinopathy does not affect the production of aqueous humor, which is the fluid that fills the front part of the eye.
However, diabetes can cause another eye condition called glaucoma, which is caused by increased pressure from too much aqueous humor.
Choice C is wrong because diabetic retinopathy does not affect the nerve innervations throughout the eye.
However, diabetes can cause another eye condition called diabetic neuropathy, which is caused by damage to the nerves that control eye movement and pupil dilation.
Correct Answer is A
Explanation
This is because levothyroxine can increase the anticoagulant effect of oral anticoagulants and increase the risk of bleeding. The nurse should check the client’s prothrombin time and international normalized ratio (INR) regularly and report any abnormal values to the prescriber.
Choice B is wrong because hypothyroidism does not increase the risk of infection.
Choice C is wrong because hypothyroidism does not affect the level of consciousness unless it is severe and causes myxedema coma.
Choice D is wrong because hypothyroidism does not cause electrolyte imbalances.
Normal ranges for prothrombin time are 11 to 13.5 seconds and for INR are 0.8 to 1.22.
