A nurse is reviewing the laboratory values for a client who has heart failure and is taking bumetanide for diuresis. For which of the following results should the nurse notify the provider?
Potassium 2.3 mEq/L (3.5-5)
Magnesium 14 mEq/L (1.3-2.1)
Carcum to mg/dL (9.9-10.5)
Sodium 136 mEq/L (136-145)
The Correct Answer is A
A. Potassium 2.3 mEq/L (3.5-5.0): This is a severely low potassium level (hypokalemia), which can cause dangerous arrhythmias, especially in a client with heart failure. Bumetanide is a loop diuretic, which can deplete potassium levels.
B. Magnesium 1.4 mEq/L (1.3-2.1): Although the magnesium level is on the lower end of normal, it is not a critical value, and the primary concern here is the potassium level.
C. Calcium 10 mg/dL (9.9-10.5): This is a normal calcium level, so there is no need to notify the provider based on this result.
D. Sodium 136 mEq/L (136-145): This is a normal sodium level, so it would not warrant notifying the provider. The critical concern is the hypokalemia.

Correct Answer is A
Explanation
A. "You will need to limit movement of the arm on the side of the pacemaker." After pacemaker placement, the client should limit movement of the arm on the side of the pacemaker to prevent dislodgement of the leads.
B. "Hiccups following pacemaker placement are an expected response." Hiccups can indicate that the pacemaker leads are stimulating the diaphragm, which is a sign of a complication and should be reported.
C. "You should avoid the use of cell phones after the pacemaker is placed." Modern pacemakers are well-shielded, and while the client should avoid placing a cell phone directly over the pacemaker, general use is safe.
D. "Swelling and redness of the operative site are normal findings for the first two weeks following the procedure." Redness and swelling at the operative site may indicate infection. The client should report these symptoms to their healthcare provider.
