The nurse reviews the client's test results.

A. Positive Chvostek's sign. Hypocalcemia increases neuromuscular excitability, leading to involuntary twitching of facial muscles when the facial nerve is tapped. This sign is a well-known indicator of calcium deficiency and reflects heightened nerve sensitivity.
B. Hypotension. While severe hypocalcemia can affect cardiovascular function, hypotension is not a primary or consistent finding. More commonly, calcium imbalances affect muscle contractions rather than directly causing low blood pressure.
C. Confusion. Hypocalcemia can cause neurological symptoms, but confusion is more common in severe or prolonged cases. Early manifestations are usually neuromuscular, such as tetany or muscle cramps, rather than cognitive impairment.
D. Positive Babinski reflex. This reflex is associated with upper motor neuron dysfunction and neurological disorders rather than electrolyte imbalances like hypocalcemia. Calcium deficiency primarily affects peripheral nerves and muscle excitability.

A. "Empty the collection chamber every 8 hr." The collection chamber should not be emptied on a regular schedule like every 8 hours. It should be emptied when it becomes full or according to facility policy. Regular monitoring of the chamber is essential to assess drainage and ensure it does not exceed capacity.
B. "Place the client in a supine position." The client should not be placed in a supine position when a chest tube is in place for a pneumothorax. The optimal position is typically sitting up or at least semi-Fowler’s position to facilitate lung expansion and drainage.
C. "Ensure the device is kept below the level of the client's chest." Keeping the chest tube drainage system below the level of the client’s chest is crucial for proper drainage and to prevent backflow of fluid or air. This position facilitates gravity drainage and helps maintain the effectiveness of the suction.
D. "Clamp the chest tube every 4 hr." Clamping the chest tube is generally not recommended unless specifically ordered by a healthcare provider. Clamping can lead to increased pressure in the pleural space and risk of tension pneumothorax. The nurse should avoid clamping unless there is a clear and appropriate reason to do so.
