What is the antidote for Warfarin?

Correct Answer: C

Rationale: The antidote for Warfarin, a common blood thinner medication, is Vitamin K. Warfarin works by inhibiting Vitamin K-dependent coagulation factors, which prevents blood clotting. In case of an overdose or excessive bleeding while taking Warfarin, administering Vitamin K can help counteract the effects of the medication and promote blood clotting.

Correct Answer: C

Rationale: Phenytoin is commonly used as an anticonvulsant and antiarrhythmic medication. In addition to its approved uses, phenytoin has demonstrated effectiveness in managing neuropathic pain, which is pain caused by damage or dysfunction of the nervous system. While this use for phenytoin is off-label, it has been shown to be beneficial in certain individuals with neuropathic pain conditions. However, it is essential for a healthcare provider to prescribe phenytoin off-label for neuropathic pain, as the dosage and monitoring may differ from its standard use for epilepsy and arrhythmias.

Correct Answer: C

Rationale: Nitroglycerin is an antianginal medication that belongs to the class of nitrates. It is used to relieve chest pain or angina by dilating blood vessels, which reduces the workload of the heart and improves blood flow to the heart muscle. Nitroglycerin helps to relax and widen blood vessels, increasing the supply of oxygen and blood to the heart. It is often used for the treatment and prevention of angina attacks. In contrast, options A, B, and D are not antianginal medications or nitrates.

Correct Answer: C

Rationale: Paradoxical bronchospasm is a major side effect of Albuterol, which is a medication commonly used to treat bronchospasm in conditions such as asthma and chronic obstructive pulmonary disease (COPD). It is characterized by a sudden worsening of breathing difficulty after using the medication, rather than an improvement. This adverse reaction can be serious and requires immediate medical attention. It is crucial for healthcare providers to monitor patients for this side effect when using Albuterol to ensure proper management and prevent complications.

Correct Answer: D

Rationale: Supplements are drugs that can be used to provide the body with essential nutrients that may be lacking. They are designed to complement the diet and help fulfill specific nutritional needs, such as vitamins, minerals, amino acids, or other substances. Unlike stimulants, depressants, or irritants that affect the central nervous system in various ways, supplements aim to provide a beneficial addition to the body's existing resources. Prophylactics, on the other hand, are preventive methods or medications used to protect against diseases or health issues, rather than addressing existing deficiencies like supplements.
