Answer to Question 1
Correct Answer: 3
The surface temperature of the body is constantly changing in response to environmental influences, and as a result, is not a reliable indicator of actual health status. To obtain accurate temperature, the core temperature, or the temperature of the deep tissues of the body, needs to be assessed. Fever causes vasodilation, not vasoconstriction. When fever is present, the skin all over the body may feel warm, not just the forehead, thus the only reliable indicator of body temperature is measuring the core temperature with a thermometer. The temperature of the skin is related to what is happening inside the body. Fever is a sign of the disruption of homeostasis in the body. This may be due to a bacterial or viral infection. Fever causes vasodilation, which can make the skin feel warm to the touch.
Answer to Question 2
Correct Answer: 1, 2, 3
The client should sit quietly for at least 5 minutes before the blood pressure is taken. Immediately assessing the blood pressure after a client walks from the waiting room to exam room may not yield an accurate reading. The client's blood pressure should be assessed on a bare arm. If the client is wearing a long-sleeved garment and it can be pushed up without constricting the arm, this is acceptable; otherwise the arm should be removed from the sleeve. Once the cuff is inflated and the nurse identifies the palpatory systolic blood pressure, the nurse should wait at least 15-30 seconds before inflating the cuff again. In order to obtain an accurate blood pressure, the client should be seated with the arm slightly flexed, supported at the level of the heart with palm facing up. Clients who have suffered trauma to the upper extremities, have shunts in the upper extremities, or have had mastectomies should not have their blood pressures assessed on the affected sides. The nurse can place the blood pressure cuff on the thigh and assess the blood pressure using the popliteal artery.
