A nurse is teaching a client who has a new prescription for an antacid to treat a gastric ulcer. Which of the following statements by the client indicates an understanding of the teaching?

Choice A reason: "If my breathing begins to feel tight, I will use the cromolyn immediately." is an incorrect statement for the client who has asthma and new prescriptions for Albuterol and Atrovent, both by nebulizer. Cromolyn is a medication that prevents the release of inflammatory substances from the mast cells in the airways, which can cause bronchospasm and asthma symptoms¹. Cromolyn is not a rescue medication, but a maintenance medication that should be used regularly to prevent asthma attacks. The client should use Albuterol, a short acting beta agonist, to relieve acute bronchospasm and wheezing.

Choice B reason: "I will be sure to take the albuterol before taking the Atrovent." is a correct statement for the client who has asthma and new prescriptions for Albuterol and Atrovent, both by nebulizer. Albuterol is a medication that relaxes the muscles in the airways and increases the airflow to the lungs, which can improve the breathing and reduce the wheezing in patients with asthma. Atrovent is a medication that blocks the action of acetylcholine, a neurotransmitter that causes bronchoconstriction and mucus secretion, which can worsen the asthma symptoms. The client should take the Albuterol before the Atrovent, as this will allow the Albuterol to open the airways and enhance the absorption and effectiveness of the Atrovent.

Choice C reason: "I will administer the medications 10 minutes apart." is an unnecessary statement for the client who has asthma and new prescriptions for Albuterol and Atrovent, both by nebulizer. The client does not need to wait 10 minutes between the administration of the two medications, as they can be given together in the same nebulizer chamber. This will save time and simplify the treatment regimen for the client. The client should follow the instructions on the medication label or the prescriber's order regarding the dosage and frequency of the nebulizer treatments.

Choice D reason: "I will use both medications immediately after exercising." is an inappropriate statement for the client who has asthma and new prescriptions for Albuterol and Atrovent, both by nebulizer. The client should not use both medications immediately after exercising, as this may not prevent or relieve exercise induced bronchospasm, a condition that causes the airways to narrow during or after physical activity. The client should use Albuterol, a short acting beta agonist, before exercising, as this will prevent the bronchospasm and allow the client to exercise safely and comfortably. The client should use Atrovent, an anticholinergic, as prescribed, usually twice a day, to control the chronic symptoms of asthma.

Choice A reason: This is incorrect. SQ (subcutaneous) administration involves injecting a drug into the fatty tissue under the skin. This route is slower than IV or IM administration, as the drug has to diffuse through the tissue before reaching the bloodstream.

Choice B reason: This is incorrect. PO (by mouth) administration involves swallowing a drug and absorbing it through the digestive system. This route is the slowest of all, as the drug has to pass through the stomach and the liver before reaching the bloodstream. The drug may also be affected by the first pass effect, which reduces its bioavailability.

Choice C reason: This is correct. IV (intravenous) administration involves injecting a drug directly into a vein. This route is the fastest of all, as the drug enters the bloodstream immediately and reaches the target site quickly. The drug also has 100% bioavailability, meaning none of it is lost or degraded.

Choice D reason: This is incorrect. IM (intramuscular) administration involves injecting a drug into a muscle. This route is faster than SQ or PO administration, as the drug can be absorbed by the capillaries in the muscle. However, it is still slower than IV administration, as the drug has to cross the muscle membrane before reaching the bloodstream.
