Why are endothelial cells in particular sensitive to the damage caused by high plasma glucose levels?
- A. Endothelial cells have a high metabolic activity
- B. Endothelial cells cannot regulate the glucose uptake
- C. Endothelial cells have a low level of antioxidants
- D. All statements provided above are correct
Correct Answer: B
Rationale: Endothelial cells drown in glucose no uptake brakes, high sugar slams them, not just metabolism or low shields. A chronic vessel weak spot nurses watch this sugar soak.

The nurse Questions which order for a client with thrombocytopenia?
- A. Apply ice to areas of trauma
- B. Administer intramuscular (IM) medication
- C. Test all urine and stool for the presence of occult blood
- D. Avoid enemas
Correct Answer: B
Rationale: Thrombocytopenia's bleed risk IM shots pierce muscle, risking hematomas, a questionable order nurses flag, as low platelets can't clot it. Ice curbs swelling, occult blood tests track bleeds, enemas avoid rectal tears all fit. Nurses challenge IM, pushing IV routes, a safety catch in this platelet-poor state.
What is an independent risk factor for the development of type 2 diabetes mellitus?
- A. Age
- B. Waist circumference
- C. Smoking
- D. All three options above
Correct Answer: D
Rationale: Type 2 diabetes brews from age cells tire; waist fat resists insulin; smoking inflammation tweaks glucose. All hit independently, stacking odds, a chronic trio nurses flag in every patient check, not just one picking off the list.
Which condition assessed by the nurse would be an early warning sign of childhood cancer?
- A. Difficulty swallowing
- B. Frequent cough or hoarseness
- C. Change in bowel and bladder habits
- D. Swellings, lumps or masses anywhere on the body
Correct Answer: D
Rationale: Childhood cancers often present with subtle, non-specific signs, but swellings, lumps, or masses anywhere on the body are a key early warning, indicating possible tumors like leukemia (lymphadenopathy), Wilms tumor, or sarcomas. Nurses must assess these palpable abnormalities, as they prompt urgent diagnostic workup imaging or biopsy to catch cancer early when treatment is most effective. Difficulty swallowing might suggest esophageal or brain tumors but isn't a common early childhood cancer sign. Frequent cough or hoarseness could indicate adult cancers (e.g., lung) or late-stage disease, not typical pediatric onset. Bowel and bladder changes are more adult-specific (e.g., colorectal cancer) or late effects in children. Lumps' prominence in pediatric guidelines underscores their priority, aligning with nursing's role in early detection to improve survival rates in young patients.
A client with a history of prostate cancer is in the clinic and reports new onset of severe low back pain. What action by the nurse is most appropriate?
- A. Assess the client's gait and balance.
- B. Ask the client about the ease of urine flow.
- C. Document the report completely.
- D. Inquire about the client's job risks.
Correct Answer: A
Rationale: Prostate cancer commonly metastasizes to bones, especially the spine, causing spinal cord compression a medical emergency that can lead to paralysis if untreated. New, severe low back pain in this context suggests possible metastasis, making gait and balance assessment the most appropriate action to check for neurological deficits (e.g., weakness, unsteady gait) indicating compression. This prioritizes client safety, as falls or worsening paralysis could result without intervention. Asking about urine flow relates to prostate obstruction, less urgent here given the pain's prominence. Documentation is essential but passive without assessment. Job risks might contribute to back pain but are secondary to cancer history. Assessing gait and balance first ensures rapid escalation if needed, reflecting oncology nursing's focus on detecting metastatic complications early.
What is an implementation intention?
- A. The decision of an organisation to implement a specific method or intervention
- B. A concrete plan to show particular behaviour in specific situations
- C. A well-considered idea of how a person can handle a relapse or difficult situations
- D. The intention to live healthier in all important areas of life
Correct Answer: B
Rationale: Implementation intention specific act, set scene, not org moves, relapse plans, or vague health kicks. Nurses cue this, a chronic action lock.
