What medication is a contraindication to Nitroglycerin

Correct Answer: D

Rationale: Erectile dysfunction drugs, such as Viagra (sildenafil), Cialis (tadalafil), and Levitra (vardenafil), are contraindicated with nitroglycerin. Both nitroglycerin and erectile dysfunction drugs can cause a sudden decrease in blood pressure when taken together, leading to a serious drop in blood pressure. This could result in dizziness, lightheadedness, fainting, and even potentially life-threatening complications like a heart attack or stroke. Therefore, it is crucial to avoid the combination of nitroglycerin with erectile dysfunction medications to prevent these adverse effects.

Correct Answer: C

Rationale: Insomnia is not a common side effect of Alprazolam. Alprazolam is a benzodiazepine medication commonly used to treat anxiety and panic disorders. Common side effects of Alprazolam include dizziness, drowsiness, and lethargy. However, it is not typically associated with causing insomnia as a side effect. If a person experiences unusual symptoms while taking Alprazolam, they should consult their healthcare provider for guidance.

Correct Answer: A

Rationale: The correct way to teach a new staff nurse to obtain a blood sample from a patient with a Portacath is to provide step-by-step instructions and demonstration. Using a Portacath requires specific knowledge and technique to prevent complications such as clot formation or infection. It is important for the preceptor nurse to properly guide and supervise the new staff nurse to ensure patient safety and accurate sample collection.

Correct Answer: D

Rationale: Vitamin E can interfere with vitamin K-dependent clotting factors, leading to prolonged prothrombin time and increased bleeding risk. Vitamin A (A), selenium (B), and vitamin D (C) do not typically affect coagulation. The nurse should assess for excessive vitamin E supplementation or dietary intake.
