- B. Retinopathy
- C. Polyneuropathy
- D. All answers are correct
Correct Answer: D
Rationale: Diabetes' micro hits kidneys, eyes, nerves all bleed small, no dodge. Nurses track this, a chronic tiny vessel trio.

Which set of classification values indicates the most extensive and progressed cancer?
- A. T1 N0 M0
- B. T10 N0 M0
- C. T1 N1 M0
- D. T4 N3 M1
Correct Answer: D
Rationale: TNM staging gauges cancer extent: T (tumor size), N (node involvement), M (metastasis). T4 N3 M1 marks the worst T4 signals a large, invasive tumor, N3 extensive nodal spread, M1 distant metastases, painting a picture of widespread, advanced disease. T1 N0 M0 is small, localized, no spread early stage. T10 isn't standard (likely T1), still less severe. T1 N1 M0 has minor nodal involvement, not extensive. T4 N3 M1's combination screams progression, guiding nurses to expect aggressive care or palliation, a stark contrast to earlier stages' hopeful prognosis, critical for planning in advanced cancer.
A client is admitted with superior vena cava syndrome. What action by the nurse is most appropriate?
- A. Administer a dose of allopurinol (Aloprim).
- B. Assess the client's serum potassium level.
- C. Gently inquire about advance directives.
- D. Prepare the client for emergency surgery.
Correct Answer: C
Rationale: Superior vena cava syndrome (SVCS) occurs when cancer (often lung or lymphoma) obstructs the superior vena cava, impairing venous return from the head and upper body. It's often a late-stage manifestation with a poor prognosis, though treatable with radiation or stenting. After stabilizing the client (e.g., with oxygen, positioning), gently inquiring about advance directives is most appropriate, as it opens a compassionate discussion about goals of care amid a potentially terminal condition. Allopurinol and potassium levels relate to tumor lysis syndrome, not SVCS. Surgery is rare for SVCS, with non-invasive options preferred. This action respects the client's autonomy and prepares for realistic outcomes, aligning with oncology nursing's holistic approach to end-of-life care in advanced disease.
It is the start of your second successive night shift on the labour ward. You have only managed to sleep for 4 h in the previous day. Your usual sleep requirement is 8 h per night. Appropriate statements regarding this situation include:
- A. Your total cumulative sleep deficit is 8 h.
- B. Your alertness will increase between 3 a.m. and 7 a.m. due to natural fluctuation in your circadian rhythm.
- C. Unintentional dural puncture during epidural insertion is more likely to occur during a night shift than during normal working hours.
- D. Sleeping for an extra 4 h will eliminate the sleep deficit.
Correct Answer: C
Rationale: Night shifts disrupt sleep and performance. After one night with 4 hours sleep (8-hour need), the deficit is 4 hours; a second night compounds it variably, but total' implies current state 8 hours overstates it without further context. Alertness dips 3-7 a.m. (circadian nadir), not increases, heightening fatigue. Night-shift studies (e.g., anaesthesia journals) show increased errors like dural puncture due to fatigue, reduced dexterity, and decision-making capacity, especially with sleep deprivation. Four extra hours reduce, not eliminate, a deficit if it's 4-12 hours cumulatively. Modafinil promotes wakefulness, not daytime sleep. The night-shift risk of dural puncture reflects fatigue's real-world impact on technical skills.
Which animal is least associated with rabies?
- A. dogs
- B. skunks
- C. foxes
- D. rats
Correct Answer: D
Rationale: Rabies dogs, skunks, foxes, bats bite big; rats rarely tag along. Nurses eye this chronic zoonotic crew.
An oncology nurse is contributing to the care of a patient who has failed to respond appreciably to conventional cancer treatments. As a result, the care team is considering the possible use of biologic response modifiers (BRMs). The nurse should know that these achieve a therapeutic effect by what means?
- A. Promoting the synthesis and release of leukocytes
- B. Focusing the patient's immune system exclusively on the tumor
- C. Potentiating the effects of chemotherapeutic agents and radiation therapy
- D. Altering the immunologic relationship between the tumor and the patient
Correct Answer: D
Rationale: BRMs (e.g., interferon, IL-2) tweak the immune-tumor dance revving up the body's attack or slowing cancer's evasion, not just pumping out leukocytes or boosting chemo/radiation. They don't laser-focus immunity but shift the balance, like marking tumors for T-cells. Nurses in oncology grasp this, knowing BRMs offer a Hail Mary when standard stuff flops, targeting that host-tumor interplay.
