Answer to Question 1
Correct Answer: 3
The statement regarding blueness is a likely statement from someone who has a long history of disorder resulting in chronic hypoxia. The nails may look blue or gray due to oxygen deprivation. Many times, clients with a long-term history of chronic hypoxia such as chronic bronchitis, will exhibit clubbing of their fingers. The fingertips will look large at the ends, not pointy and narrow. Clients with lung problems resulting in chronic hypoxia will more likely to complain that their nails are soft and spongy. Ridges in the nails are more likely the result of another disorder such as a nutritional deficiency.
Answer to Question 2
Correct Answer: 3
A difference of readings 10 mmHg or more between arms may indicate an obstruction of arterial blood flow to one arm and is considered an abnormal finding. After repeating the procedure and determining the results were the same, the nurse would not necessarily assume that the technique was faulty. Client anxiety may result in a higher blood pressure reading. It would not result in a difference between blood pressures assessed in each arm. If the client is developing clinical manifestations associated with shock, the nurse would most likely determine that the client's blood pressure is lower than normal. Shock would not result in a difference between blood pressures assessed in each arm.
