Correct Answer: B

Rationale: The patient's signs of ecchymoses and petechiae are suggestive of thrombocytopenia, which is a common complication of leukemia. Thrombocytopenia is a condition characterized by a low platelet count, leading to abnormal bleeding. Checking the patient's most recent platelet level is crucial to assess the severity of thrombocytopenia and guide further interventions. Initiating measures to prevent venous thromboembolism (VTE) (Choice A) is not directly related to the patient's current signs. Placing the patient on protective isolation (Choice C) is not necessary for ecchymoses and petechiae. Ambulating the patient (Choice D) is not appropriate without addressing the underlying cause of abnormal bleeding.

Correct Answer: C

Rationale: Monitoring hemoglobin and hematocrit is essential to assess the effectiveness of ruxolitinib in treating myelofibrosis. Ruxolitinib works by inhibiting JAK1 and JAK2, which are involved in the signaling pathways that regulate blood cell production. Therefore, monitoring hemoglobin and hematocrit levels can provide valuable information on how well the drug is managing the disease. Blood pressure, white blood cell count, and spleen size are not direct indicators of the treatment's effectiveness in myelofibrosis.

Correct Answer: C

Rationale: The correct answer is C: Muscle weakness. In patients with multiple myeloma who have developed hypercalcemia, monitoring for muscle weakness is crucial. Hypercalcemia can lead to muscle weakness due to its effects on neuromuscular function. Choice A, increased heart rate, is more commonly associated with conditions like dehydration or anxiety rather than hypercalcemia. Choice B, decreased urine output, is commonly seen in conditions leading to acute kidney injury rather than hypercalcemia. Choice D, hypertension, is not a typical symptom of hypercalcemia and is more commonly associated with other conditions like uncontrolled high blood pressure.

Correct Answer: A

Rationale: The correct answer is A, Hypercalcemia. In multiple myeloma, bone destruction can lead to the release of calcium from the bones into the bloodstream, causing hypercalcemia. This imbalance is commonly seen in patients with multiple myeloma. Choice B, Hyperproteinemia, is not typically associated with bone destruction in multiple myeloma. Choice C, Elevated serum viscosity, and Choice D, Elevated RBC count, are not directly related to the bone destruction seen in multiple myeloma.

Correct Answer: A

Rationale: The correct action by the nurse is to assess the client's gait and balance. Severe low back pain in a client with a history of prostate cancer may indicate spinal cord compression, a serious complication. Assessing gait and balance can help determine if there is any spinal cord involvement, which requires immediate medical attention. Asking about changes in urinary symptoms (choice B) is important to assess for possible urinary obstruction, but assessing gait and balance takes precedence due to the risk of spinal cord compression. Documenting the report thoroughly (choice C) is essential but not the most immediate action needed. Inquiring about recent activities (choice D) is not as critical as assessing for spinal cord involvement.
