1. When teaching a client with a prescription for Cephalexin, which of the following instructions should the nurse include?

A. Take the medication with an antacid.
B. Avoid dairy products while taking this medication.
C. Expect your stools to turn black.
D. Complete the full course of medication.

Correct answer: D

Rationale: The correct instruction for a client prescribed with Cephalexin is to complete the full course of medication. This is crucial to ensure the infection is completely treated and to reduce the risk of antibiotic resistance. Choices A, B, and C are incorrect. Taking Cephalexin with an antacid is generally not recommended as it may reduce its effectiveness. While dairy products can interfere with certain antibiotics, they do not have a direct interaction with Cephalexin. Stools turning black is not an expected side effect of Cephalexin.

2. What is a severe adverse effect of warfarin?

A. Bleeding
B. Arrhythmias
C. Blurred vision
D. Bradycardia

Correct answer: A

Rationale: A severe adverse effect of warfarin is bleeding. Warfarin is an anticoagulant medication that works by inhibiting blood clotting factors, which can lead to an increased risk of bleeding. Excessive bleeding can occur internally or externally, and it is crucial for individuals taking warfarin to be aware of this potential complication and seek medical attention if they experience any signs of bleeding. Arrhythmias, blurred vision, and bradycardia are not typically associated with warfarin use, making them incorrect choices.

A. Antidiabetics, biguanides
B. Mood stabilizers

Rationale: Lithium is classified as a mood stabilizer due to its primary use in managing bipolar disorder, where it helps stabilize mood swings and prevent episodes of mania and depression. While it can have other effects on the body, its main therapeutic role lies in its mood-stabilizing properties. Choices A, C, and D are incorrect as lithium is not classified as antidiabetics, biguanides, antiarrhythmics, anticonvulsants, or vascular headache suppressants. Its main pharmacological class is mood stabilizers.
