The nurse is caring for a client who is being treated on the oncology unit with a diagnosis of lung cancer with bone metastases. The client reports a new onset of weakness with abdominal pain and further assessment suggests that the client likely has a fluid volume deficit. The nurse should recognize that this client may be experiencing which electrolyte imbalance?
Hypomagnesemia
Hyperphosphatemia
Hypokalemia
Hypercalcemia
The Correct Answer is D
A. Hypomagnesemia: While hypomagnesemia can cause weakness and other symptoms, it is less commonly associated with fluid volume deficit compared to other imbalances in this context.
B. Hyperphosphatemia: Hyperphosphatemia is typically associated with renal failure or specific conditions, but it does not directly correlate with fluid volume deficit or the symptoms described.
C. Hypokalemia: Hypokalemia can cause weakness and abdominal pain, but it is less likely to be directly associated with the type of symptoms presented in this oncology context.
D. Hypercalcemia: This is the correct choice. Hypercalcemia, often associated with bone metastases, can lead to weakness, abdominal pain, and dehydration, as well as contribute to fluid volume deficit through increased urinary calcium excretion and renal effects.

Correct Answer is C
Explanation
A. Client's serum pH is 7.41: This is within the normal range for blood pH (7.35-7.45) and does not specifically indicate a potassium deficit.
B. Client has a stage 2 sacral wound: This is related to skin integrity and does not directly impact potassium levels.
C. Client requires continuous nasogastric suction: Continuous nasogastric suction can lead to the loss of potassium as it removes gastric contents, which may include electrolytes.
D. Client has a history of adrenal insufficiency: While adrenal insufficiency can affect electrolyte balance, continuous nasogastric suction is a more immediate risk for potassium deficit.
Correct Answer is A
Explanation
A. Warfarin (Coumadin): This is the correct choice. Warfarin is an anticoagulant that increases the risk of bleeding during and after surgery. The surgeon needs to be notified to consider holding the medication and to adjust the surgical plan if necessary.
B. Gabapentin (Neurontin): While important for pain management, it does not significantly impact surgical procedures or bleeding risk.
C. Xanax (Alprazolam): This medication is a benzodiazepine used for anxiety, which might be relevant for preoperative anxiety but does not require immediate notification of the surgeon.
D. Atenolol (Tenormin): This beta-blocker is used for hypertension and heart conditions but does not require immediate notification of the surgeon unless there are specific cardiac concerns related to surgery.
