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: B

Rationale: Before administering Digoxin, it is crucial for the nurse to count the patient's apical pulse for 1 minute. Digoxin is a medication commonly prescribed to manage heart conditions such as heart failure and certain irregular heartbeats. Since Digoxin works by helping the heart beat stronger and at a more normal rhythm, it is essential to monitor the patient's heart rate before administering the medication. Counting the apical pulse for 1 minute allows for an accurate assessment of the patient's baseline heart rate, which is crucial in determining whether it is safe to administer Digoxin. If the heart rate is too low (bradycardia), administering Digoxin could potentially cause further complications. Therefore, assessing the apical pulse beforehand is a critical step in ensuring the safe administration of Digoxin.

Correct Answer: A

Rationale: Warfarin is an anticoagulant medication commonly used to prevent blood clots. One of the most severe adverse effects of warfarin is the risk of bleeding. This can occur in various parts of the body, such as the gastrointestinal tract, brain, or other organs. Bleeding complications can range from minor bruising to life-threatening hemorrhages, especially if warfarin levels are not properly monitored. Patients taking warfarin should be closely monitored for signs of bleeding, and their medication dosages should be adjusted as needed to maintain a balance between preventing clotting and avoiding excessive bleeding.

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: Increasing the temperature does not result in local analgesia. In fact, higher temperatures can often lead to increased pain sensitivity. Local analgesia is achieved through methods such as chemically or physically damaging nerve trunks, stimulating large fiber nerve activity, or rendering tissue anemic. These procedures work by interrupting the transmission of pain signals to the brain or by reducing the sensitivity of local nerve endings to pain stimuli.
