A client who received 6 units of packed red blood cells 3 days ago for a lower gastrointestinal (GI) bleed is now displaying signs of shortness of breath with occasional stridor and is reporting muscle cramping.
Reference Range:
Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)]
Magnesium [Adult: 1.3 to 2.1 mEq/L (0.65 to 1.05 mmol/L)]
Calcium [9 to 10.5 mg/dL (2.3 to 2.6 mmol/L)]
Sodium (136 to 145 mEq/L (136 to 145 mmol/L)]
Which serum laboratory value should the nurse immediately report to the healthcare provider?
Potassium 4.7 mEq/L (4.70 mmol/L).
Magnesium 2.1 mEq/L (0.86 mmol/L).
Calcium 6.5 mg/dL (1.63 mmol/L).
Sodium 135 mEq/L (135 mmol/L).
The Correct Answer is C
Choice A reason: Potassium 4.7 mEq/L (4.70 mmol/L) is within the normal reference range of 3.5 to 5 mEq/L (3.5 to 5 mmol/L). Potassium is an electrolyte that helps regulate the balance of fluids and acids in the body, as well as the function of nerves and muscles. A high potassium level (hyperkalemia) can cause muscle weakness, irregular heartbeat, and cardiac arrest. A low potassium level (hypokalemia) can cause muscle cramps, fatigue, and arrhythmias.
Choice B reason: Magnesium 2.1 mEq/L (0.86 mmol/L) is within the normal reference range of 1.3 to 2.1 mEq/L (0.65 to 1.05 mmol/L). Magnesium is an electrolyte that helps regulate the activity of enzymes, muscles, and nerves, as well as the balance of calcium and potassium in the body. A high magnesium level (hypermagnesemia) can cause nausea, vomiting, flushing, muscle weakness, and respiratory depression. A low magnesium level (hypomagnesemia) can cause muscle twitching, tremors, seizures, and cardiac arrhythmias.
Choice C reason: Calcium 6.5 mg/dL (1.63 mmol/L) is below the normal reference range of 9 to 10.5 mg/dL (2.3 to 2.6 mmol/L). Calcium is an electrolyte that helps regulate the function of muscles, nerves, bones, and blood clotting. A high calcium level (hypercalcemia) can cause nausea, vomiting, constipation, confusion, kidney stones, and bone pain. A low calcium level (hypocalcemia) can cause muscle spasms, cramps, tingling, numbness, and stridor (a high-pitched sound when breathing). **This is a critical value that should be immediately reported to the healthcare provider**, as it can indicate a serious condition such as acute pancreatitis, sepsis, or massive blood transfusion.
Choice D reason: Sodium 135 mEq/L (135 mmol/L) is slightly below the normal reference range of 136 to 145 mEq/L (136 to 145 mmol/L). Sodium is an electrolyte that helps regulate the balance of fluids and acids in the body, as well as the function of nerves and muscles. A high sodium level (hypernatremia) can cause thirst, dry mouth, confusion, seizures, and coma. A low sodium level (hyponatremia) can cause headache, nausea, vomiting, fatigue, muscle weakness, and confusion.

Correct Answer is D
Explanation
Choice A reason: Measuring capillary glucose level is not a priority action for a client with a rigid abdomen and rebound tenderness. These signs indicate peritonitis, which is a serious complication of IBD that requires immediate attention. Corticosteroids can increase blood glucose levels, but this is not an urgent concern in this situation.
Choice B reason: Encouraging ambulation in the room is not appropriate for a client with a rigid abdomen and rebound tenderness. These signs indicate peritonitis, which is a serious complication of IBD that requires immediate attention. Ambulation can worsen the pain and inflammation, and increase the risk of bowel perforation.
Choice C reason: Monitoring for bloody diarrheal stools is important for a client with IBD, but not a priority action for a client with a rigid abdomen and rebound tenderness. These signs indicate peritonitis, which is a serious complication of IBD that requires immediate attention. Bloody stools can be a sign of ulceration or bleeding in the bowel, but they are not specific to peritonitis.
Choice D reason: Obtaining vital sign measurements is the priority action for a client with a rigid abdomen and rebound tenderness. These signs indicate peritonitis, which is a serious complication of IBD that requires immediate attention. Vital signs can reveal signs of infection, inflammation, shock, and organ failure, which can guide the appropriate interventions and treatments.
Correct Answer is A
Explanation
Choice A reason: Weight gain of 2 pounds (0.91 kg) in one day is a sign of fluid retention, which occurs in SIADH due to excessive secretion of antidiuretic hormone (ADH). ADH causes the kidneys to reabsorb water and reduce urine output, leading to hyponatremia and hypervolemia.
Choice B reason: Fremitus over the chest wall is a sign of increased vibration or air movement in the lungs, which can indicate pneumonia, bronchitis, or pleural effusion. These are not related to SIADH, but may be complications of head injury or fluid overload.
Choice C reason: Serum sodium of 150 mEq/L (150 mmol/L) is a sign of hypernatremia, which is a high level of sodium in the blood. This is the opposite of what happens in SIADH, where sodium levels are low due to dilution by excess water.
Choice D reason: Urine specific gravity of 1.004 is a sign of diluted urine, which indicates low concentration of solutes in the urine. This is also the opposite of what happens in SIADH, where urine is concentrated and has a high specific gravity.
