A nurse is caring for a client who requires isolation for active pulmonary tuberculosis. Which of the following precautions should the nurse include when creating a sign to post outside of the client's room? (Select all that apply.)

A. Diluting each medication with tap water is not a recommended practice. It's important to administer medications in their prescribed form to ensure the client receives the correct dose.
B. Pinching the tube prior to attaching the medication syringe helps prevent the medication from being immediately pulled into the suction equipment. This allows the medication to stay in the stomach for absorption.
C. Reattaching the suction directly after administering the medication would
immediately start suctioning again, which could pull the medication out of the stomach before it has a chance to be absorbed.
D. Mixing the three medications together is not recommended, as some medications may interact with each other, potentially leading to undesirable effects. Each medication should be administered separately to ensure proper absorption and effectiveness.

A) The dorsal surface of the foot is not the most reliable site to assess for cyanosis in individuals with dark skin because the skin pigmentation can mask the bluish tint that indicates reduced oxygenation.
B) Similarly, the dorsal surface of the hand may not clearly show cyanosis due to the thickness and pigmentation of the skin, which can obscure the color change.
C) The pinnae of the ears may also not be the best indicator of cyanosis in dark-skinned individuals because peripheral areas like the ears can be affected by environmental temperatures, leading to misleading color changes.
D) The conjunctivae, however, are a mucous membrane where the skin pigmentation does not affect visibility. Therefore, it is an appropriate site for assessing cyanosis as it allows for the observation of subtle changes in color that indicate hypoxia. This is why the conjunctivae are the correct site to examine for cyanosis in a client with dark skin.
