Correct Answer: A

Rationale: The correct answer is to assess for mood changes. When administering escitalopram, it is crucial to evaluate mood changes first because the medication may take some time to demonstrate its full effects on the patient's mood. Assessing blood pressure, heart rate, or liver function is not the priority when administering escitalopram, as these parameters are not directly impacted acutely by this medication.

Correct Answer: A

Rationale: Corrected Rationale: When administering warfarin, it is crucial to verify the patient's INR levels. INR monitoring is essential to ensure that the patient is receiving the correct dose of warfarin for their condition and to minimize the risk of bleeding. Choices B, C, and D are incorrect because administering warfarin with food, monitoring blood glucose levels, and assessing liver function are not directly related to the safe administration and monitoring of warfarin therapy.

Correct Answer: A

Rationale: The correct answer is A: Third trimester of pregnancy. Salicylic acid is contraindicated during the third trimester of pregnancy due to the risk of complications for both the mother and the fetus. Thrombocytopenia (choice B) is not a contraindication to salicylic acid therapy. Coronary artery disease (choice C) is not a specific contraindication to salicylic acid therapy. However, caution should be exercised in patients with coronary artery disease due to the antiplatelet effects of salicylic acid. Adolescents with chickenpox (choice D) should not be given salicylic acid due to the risk of Reye Syndrome, a rare but serious illness.

Correct Answer: D

Rationale: Atorvastatin requires monitoring for liver function due to its potential to cause liver abnormalities. It can also lead to muscle pain or weakness, a condition known as myopathy. Choice C is incorrect as atorvastatin is contraindicated during pregnancy due to potential harm to the fetus, making choices A and B the correct options to include in patient education.

Correct Answer: B

Rationale: The correct answer is B: Smallpox, anthrax, botulism. These are known biological weapons that can be used in mass casualty situations. Rabies, cholera, and meningitis (Choice A) are not typically used as biological weapons. Ebola, hepatitis B, and tetanus (Choice C) are serious diseases but are not commonly associated with biological warfare. Tuberculosis, influenza, and measles (Choice D) are infectious diseases but are not typically used as biological weapons of mass destruction.
