A client is being discharged on warfarin (Coumadin) therapy. What discharge instructions is the nurse required to provide?

Correct Answer: A

Rationale: The correct answer is A: Dietary restrictions. Warfarin interacts with vitamin K, so consistent intake of vitamin K-rich foods is crucial for maintaining the drug's effectiveness. Choices B, C, and D are incorrect as driving restrictions, follow-up laboratory monitoring, and possible drug interactions are important but not specific discharge instructions for warfarin therapy. Warfarin therapy requires strict dietary management to prevent complications like clotting or bleeding.

Correct Answer: A

Rationale: The correct answer is A: Skin. Pacinian corpuscles are sensory receptors responsible for detecting pressure and vibration. They are located in the skin's deeper layers, particularly in the subcutaneous tissue. These receptors adapt quickly to changes in pressure, making them ideal for detecting dynamic stimuli. Choices B, C, and D are incorrect as Pacinian corpuscles are not typically found in the alimentary canal, liver, or lungs. The specific location of Pacinian corpuscles in the skin is crucial for their function in sensing external stimuli and transmitting sensory information to the brain.

Correct Answer: A

Rationale: The correct answer is A because vibrissae, also known as whiskers, are essential for a rabbit's navigation and sensing its surroundings. Without whiskers, a rabbit may struggle to move freely and may become disoriented. Choice B is incorrect as speed is not solely determined by the presence of vibrissae. Choice C is incorrect as the rabbit may still attempt to move even without vibrissae. Choice D is incorrect as removing vibrissae will have an impact on the rabbit's mobility and spatial awareness.

Correct Answer: D

Rationale: The correct answer is D: Lysozyme. Lysozyme is an anti-bacterial enzyme found in tears that helps protect the eyes from infections. It works by breaking down the cell walls of bacteria, thus preventing their growth. Lacrimin (A) is a protein involved in tear production, not an anti-bacterial enzyme. Interferon (B) is a protein produced by the immune system to fight viruses, not found in tears. Pepsin (C) is a digestive enzyme produced in the stomach, not present in tears. Therefore, the correct answer is D because lysozyme is the specific anti-bacterial enzyme found in tears.

Correct Answer: C

Rationale: The correct answer is C: Hippopotamus. Sudorific glands are sweat glands responsible for regulating body temperature. Hippopotamuses have sudorific glands confined to their external ears, which help them cool down. Deer and kangaroos do not have sudorific glands in their external ears. Choice D, "Acting as receptor organ," is vague and unrelated to the function of sudorific glands.
