Which of the following cancer patients could potentially be placed together as roommates?
- A. A patient with a neutrophil count of 1000/mm³
- B. A patient who underwent debulking of a tumor to relieve pressure
- C. A patient receiving high-dose chemotherapy after a bone marrow harvest
- D. A patient who is post-op laminectomy for spinal cord compression
Correct Answer: B
Rationale: Roommate pairing hinges on infection risk and care needs. The debulking patient tumor reduced for symptom relief and post-laminectomy patient spinal decompression both underwent palliative surgeries, not inherently immunocompromised, making them compatible. A neutrophil count of 1000/mm³ signals moderate neutropenia, needing isolation to dodge infections. High-dose chemotherapy post-bone marrow harvest obliterates immunity, demanding strict protection. The surgical pair's stability, lacking acute immune suppression, allows safe cohabitation, a nurse's practical call to optimize space and reduce cross-infection risks in cancer care settings.
A nurse sets an infusion pump to infuse 1 L of D5NS at the rate of $100 \mathrm{~mL} / \mathrm{hr}$. How many hours will it take to complete the infusion?
- A. 8
- B. 10
- C. 12
- D. 14
Correct Answer: B
Rationale: Math rules IV timing 1 L (1000 mL) at 100 mL/hr divides to 10 hours, a straightforward calc nurses nail for fluid planning. Missteps like 8 or 12 flub the rate; 14's way off. Precision here ensures hydration or med delivery hits the mark, a basic skill keeping care on track.

What is the result of bariatric surgery as a therapy for morbid obesity?
- A. Reduced insulin sensitivity
- B. Increased insulin sensitivity

The nurse is caring for a client who was recently diagnosed with hemophilia. Which of the following laboratory tests is consistent with that diagnosis?
- A. Prolonged activated partial thromboplastin time
- B. Prolonged prothrombin time
- C. Decreased platelet count
- D. Decreased bleeding time
Correct Answer: A
Rationale: Hemophilia factor VIII or IX lack stretches aPTT, as intrinsic clotting lags, a lab fit for this X-linked bleed fest. PT stays normal extrinsic path's fine. Platelets don't drop; bleeding time's off-base. Nurses spot prolonged aPTT, confirming hemophilia's clotting chaos, guiding factor therapy in this bloody diagnosis.
