An oncology nurse is caring for a patient with multiple myeloma who is experiencing bone destruction. When reviewing the patient's most recent blood tests, the nurse should anticipate what imbalance?

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: 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: In the context of AML, the 5-year survival rate significantly decreases with age. The 5-year survival rate for patients over 75 years old is less than 2% compared to 43% for those 50 years or younger, and 19% for those between 50 and 64 years. Choice A is incorrect as early diagnosis does not necessarily guarantee good outcomes in AML. Choice B is inaccurate as the 5-year survival rate is not approximately 50% for older adults with AML. Choice D is incorrect as survival rates for AML patients are influenced by various factors beyond just the pre-illness level of health.

Correct Answer: C

Rationale: The correct answer is that normal cells undergo apoptosis, which is a programmed cell death process essential for maintaining tissue homeostasis. Choice A is incorrect as normal cells do have specific functions. Choice B is incorrect as the size of the nucleus may vary but is not a defining characteristic of normal cells. Choice D is incorrect as the color of the nucleus is not a standard characteristic of normal cells.

Correct Answer: A

Rationale: The correct action for the nurse to take when observing swelling and pain at the IV site during the administration of doxorubicin hydrochloride is to stop the administration of the drug immediately. Doxorubicin hydrochloride can cause severe tissue damage, so discontinuing the infusion is crucial to prevent further harm to the patient. Notifying the physician is important, but it should not take precedence over stopping the drug. Continuing the infusion, even at a decreased rate, can exacerbate tissue damage. Applying a warm compress is not appropriate in this situation and may worsen the tissue injury caused by the drug.

Correct Answer: A

Rationale: The correct action by the nurse is to assess the client's blood pressure and pulse. Difficulty breathing can be a sign of various conditions, including cardiac issues. Assessing blood pressure and pulse helps in determining the client's hemodynamic status and identifying any cardiovascular compromise. Option B is less crucial as attaching the client to a pulse oximeter may provide oxygen saturation levels but does not directly assess cardiac output. Option C is not the priority in this situation as the client's difficulty breathing is a more urgent concern. Option D is incorrect as urgent radiation therapy is not indicated based on the client's presentation.

Correct Answer: D

Rationale: The correct answer is D: Invading healthy host tissues. Invasion is the process where malignant cells grow into surrounding healthy tissues, allowing the cancer to spread to other parts of the body. Choices A, B, and C are incorrect. Adhering to primary tumor cells does not involve the transfer of cells to other locations, inducing mutation of cells of another organ is not a mechanism of cell transfer, and phagocytizing healthy cells refers to the process of engulfing and digesting cells, which is not a method of cancer cell transfer.

Correct Answer: B

Rationale: The correct answer is B. The best time to perform a testicular self-examination is after a warm shower when the scrotal skin is relaxed. This makes it easier to detect any abnormalities. Choice A is incorrect because the examination should ideally be done while standing. Choice C is incorrect as the client should use both hands to roll each testicle between the thumb and fingers to feel for any lumps or changes in size. Choice D is incorrect because testicular self-examinations are recommended to be done monthly, not every 6 months, to monitor changes in the testicles.

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.
