Answer to Question 1
C
Feedback:
The nurse should report to the physician the presence of hypokalemia in this client because the potassium level is below the normal range of 3.5 to 5.5 mEq/L. Sodium, chloride, and calcium levels in this client are within the normal range. The normal range for sodium is 135 to 145 mEq/L, chloride 95 to 105 mEq/L, and calcium 4.5 to 5.5 mEq/L.
Answer to Question 2
B
Feedback:
The nurse should take BP and pulse initially in both arms, especially for a client with vascular disease or if the reading is not within normal range. A difference of 5 to 10 points commonly exists between arms. Readings of greater than a 10-point difference indicate arterial occlusion in the arm with the lower pressure. Readings of greater than a 10-point difference between both arms do not indicate a circulatory problem, hemorrhage, shock, or orthostatic hypotension. Any pressure that is much higher than normal for the person's age (hypertension) is a sign of a circulatory problem. A very low BP (hypotension) may indicate hemorrhage or shock. When a severe drop in BP occurs, the condition is known as orthostatic hypotension.
