Which of the following assessment findings or results will the nurse plan to obtain in order to determine the effectiveness of the prescribed calcium carbonate for a client with chronic kidney disease?

A. Cardiac tamponade: Cardiac tamponade typically presents with hypotension, jugular venous distension, and muffled heart sounds (Beck’s triad). While shortness of breath may occur, the use of accessory muscles is not a defining feature. Chest pain is usually retrosternal and not always associated with respiratory distress.

B. Pneumothorax: Pneumothorax presents with chest pain, dyspnea, and increased use of accessory muscles due to impaired lung expansion. These signs indicate compromised ventilation and decreased oxygenation. Trauma is a common cause, making this a likely condition. Rapid assessment and intervention are essential.

C. Aspiration: Aspiration can cause sudden coughing, choking, and possible hypoxia, but it is not typically associated with chest trauma or immediate accessory muscle use. It is less likely in the context of a motor vehicle accident.

D. Splenic laceration: Splenic injury usually presents with left upper quadrant abdominal pain, referred shoulder pain, and signs of internal bleeding such as hypotension and tachycardia. Respiratory distress and accessory muscle use are not typical features.

A. Cool, clammy skin: During the compensatory stage of shock, the sympathetic nervous system triggers peripheral vasoconstriction to maintain blood flow to vital organs. This shunts blood away from the skin, causing it to become cool and moist. These changes reflect early compensatory mechanisms attempting to stabilize perfusion.

B. Decreased heart rate: A decreased heart rate is not expected in the compensatory stage, as the body typically increases heart rate to maintain cardiac output. Sympathetic activation drives tachycardia to compensate for reduced circulating volume. A slowed pulse would suggest a different clinical problem unrelated to early shock.

C. Hyperactive bowel sounds: Shock states generally reduce perfusion to nonessential organs, including the gastrointestinal tract. This leads to diminished or hypoactive bowel sounds, not hyperactivity. Blood flow is redirected to support the heart and brain rather than digestion.

D. Increased urine output: In early shock, the kidneys receive reduced blood flow as the body conserves fluid and maintains central perfusion. This results in decreased, not increased, urine output. Reduced renal perfusion is a key early indicator of volume loss. Increased output contradicts expected physiological responses in shock.
