A nurse is providing client education to a client who has had corticosteroids prescribed.
What drug should the nurse teach the client to avoid while taking the corticosteroids?

Dimenhydrinate.

Aspirin.

Ibuprofen.

Famotidine.

Answer and Explanation

The Correct Answer is B

The client should avoid taking aspirin while taking corticosteroids because of the potential drug-drug interaction between them. This interaction may cause a reduction in the blood levels of aspirin and decrease its effectiveness. It may also increase the risk of gastrointestinal side effects such as inflammation, bleeding, ulceration, and perforation.

Choice A is wrong because dimenhydrinate is an antihistamine that is used to prevent and treat nausea, vomiting, and dizziness.

It does not have a significant interaction with corticosteroids.

Choice C is wrong because ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is used to relieve pain, inflammation, and fever.

It has a similar interaction with corticosteroids as aspirin, but it is less potent and less likely to cause bleeding.

Choice D is wrong because famotidine is a histamine-2 receptor antagonist that is used to treat and prevent ulcers, gastroesophageal reflux disease (GERD), and other conditions that cause excess stomach acid.

It does not have a significant interaction with corticosteroids.

Correct Answer is B

Explanation

Theophylline is a bronchodilator that is used to treat asthma and COPD.

It works by relaxing the smooth muscles of the airways and increasing airflow to the lungs.

However, theophylline has a narrow therapeutic range and can cause side effects such as nausea, vomiting, insomnia, tremors, and cardiac arrhythmias if the blood level is too high.

Caffeine is a stimulant that can increase the effects of theophylline and raise the risk of toxicity.

Therefore, patients taking theophylline should avoid caffeine-containing beverages such as coffee, tea, cola, and energy drinks.

Choice A is wrong because eating foods high in potassium has no effect on theophylline metabolism or action.

Potassium is an electrolyte that is important for nerve and muscle function, but it does not interact with theophylline.

Choice C is wrong because taking the medication on an empty stomach can increase the absorption of theophylline and cause gastric irritation.

Theophylline should be taken with food or milk to reduce stomach upset and prevent fluctuations in blood levels.

Choice D is wrong because limiting fluid intake to 1,000 mL a day can cause dehydration and increase the concentration of theophylline in the blood.

Theophylline

A. Monitoring the client for increased bruising. B. Assessing for signs and symptoms of infection. C. Assessing the client’s level of consciousness. D. Monitoring the client’s electrolyte levels.

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.
