Correct Answer: D

Rationale: In the immediate postoperative period following a gastrectomy, any bloody drainage from the nasogastric (NG) tube is concerning and requires prompt evaluation. This could indicate potential complications such as bleeding from the surgical site, erosion, or other postoperative issues. Notifying the healthcare provider immediately is crucial to ensure that the patient receives timely assessment and intervention. The presence of blood may necessitate further diagnostic procedures, interventions, or changes in management to prevent serious complications.

Correct Answer: B

Rationale: Hematuria, or blood in the urine, is the most common and distinctive symptom associated with bladder cancer. It can present as either gross hematuria (visible blood) or microscopic hematuria (detected only through urinalysis). The presence of blood in the urine often prompts further evaluation for potential underlying causes, including bladder cancer. It is crucial for healthcare providers to recognize this symptom, as early detection significantly impacts treatment outcomes.

Correct Answer: B

Rationale: An increased lymphocyte count (lymphocytosis) is always present in patients with CLL.

Correct Answer: B

Rationale: In the management of breast cancer, particularly after procedures such as a mastectomy, it is important to position the patient in a way that promotes healing and comfort. However, lying down with 1-2 pillows is not a standard practice for postoperative care. Instead, patients are often advised to elevate the affected arm to reduce swelling and promote drainage, and they may benefit from sleeping in a more upright position if they are experiencing discomfort. The focus should be on facilitating recovery rather than simply lying down.

Correct Answer: A

Rationale: In patients with multiple myeloma, hypercalcemia is a common complication due to the release of calcium from the bones as a result of osteolytic lesions. One of the early symptoms of hypercalcemia is polyuria, or increased urine output. This occurs because elevated calcium levels can lead to impaired renal function and increased renal excretion of calcium, which results in increased urine production. Early recognition of polyuria can help prompt further evaluation and management of hypercalcemia, as untreated hypercalcemia can lead to more severe complications.
