  d. Use a stethoscope with the longest tubing available

Question 2

Answer to Question 1

B
Always place the stethoscope directly on the skin because clothing obscures the sound. Position the diaphragm to make a tight seal against the patient's skin. Exert enough pressure on the di-aphragm to leave a temporary red ring on the patient's skin when the diaphragm is removed. Make sure the plastic or rubber earpieces fit snugly in the ear canal and that the binaurals are an-gled and strong enough so the earpieces stay firmly in place without causing discomfort. The polyvinyl tubing is flexible and 30 to 45 cm (12 to 18 inches) in length. Longer tubing decreases sound wave transmission.

Answer to Question 2

C
When the nurse washes one group with soap and water and the other with Betadine, the nurse is answering the question or hypothesis. Identifying the problem would be an increase in infections or adverse reactions from Betadine. Forming the question or hypothesis would be, Does soap and water vs Betadine reduce the incidence of infections or adverse reactions? Evaluating the results would occur when the nurse compared the incidence of infection or adverse reactions for each of the two groups.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
