A nurse is caring for four clients who have drainage tubes.
Which of the following clients should the nurse recognize as being at risk for hypokalemia?
The client who has a nasogastric (NG) tube to suction.
The client who has a tracheostomy tube attached to humidified oxygen.
The client who has an indwelling urinary catheter to gravity drainage.
The client who has a chest tube to water seal.
The Correct Answer is A
Choice A rationale
Patients with a nasogastric (NG) tube to suction are at risk for hypokalemia. Hypokalemia, or low potassium levels, can occur due to increased losses from the gastrointestinal tract, which can occur with NG tube suction. Potassium is an essential electrolyte that plays a vital role in many bodily functions, particularly in the heart and cardiovascular system. Therefore, any condition or intervention that leads to a significant loss of potassium, such as NG tube suction, can potentially lead to hypokalemia.
Choice B rationale
A tracheostomy tube attached to humidified oxygen is primarily used to help a patient breathe. It does not typically contribute to potassium loss or imbalance. Therefore, it is not likely to increase the risk of hypokalemia.
Choice C rationale
An indwelling urinary catheter to gravity drainage is used to drain urine from the bladder. While the kidneys do play a role in maintaining potassium balance, the use of a urinary catheter itself does not typically lead to significant potassium loss or increase the risk of hypokalemia.
Choice D rationale
A chest tube to water seal is used to remove air, fluid, or pus from the pleural space to help the lungs expand properly. It does not typically contribute to potassium loss or imbalance.
Therefore, it is not likely to increase the risk of hypokalemia.

Correct Answer is D
Explanation
Choice A rationale
An erythrocyte sedimentation rate (ESR) is a blood test that can detect and monitor inflammation in the body. It measures the rate at which red blood cells (erythrocytes) in a test tube separate from blood serum over time, with the rate being faster in people with inflammatory diseases. While it can be elevated in many conditions, including liver disease, it is not specific to liver disease and therefore would not typically be used to confirm a diagnosis of liver disease.
Choice B rationale
D-dimer is a small protein fragment present in the blood after a blood clot is degraded by fibrinolysis. It is typically used to rule out thrombosis (blood clots), not to diagnose liver disease.
Choice C rationale
C-reactive protein (CRP) is a protein made by the liver and sent into the bloodstream in response to inflammation. While it can be elevated in many conditions, including liver disease, it is not specific to liver disease and therefore would not typically be used to confirm a diagnosis of liver disease.
Choice D rationale
Albumin is a protein made by the liver, and measuring its levels can help diagnose liver disease. When the liver is damaged, it can’t make enough albumin, so the level of albumin in the blood gets lower. This is why albumin is often used as a marker of liver function, and why it would be anticipated in the laboratory values ordered to confirm a diagnosis of liver disease.

Correct Answer is B
Explanation
Choice A rationale
While Vitamin B is important for overall health, it is not specifically known to promote wound healing.
Choice B rationale
Protein is essential for wound healing. It helps to repair body tissues and is vital for skin repair and immunity. Inadequate protein intake can impair collagen formation and slow down the wound healing process.
Choice C rationale
While calcium is important for bone health, it is not specifically known to promote wound healing.
Choice D rationale
Vitamin D helps the body absorb calcium, but it is not specifically known to promote wound healing.
