Foam cells are a prominent feature of atherosclerosis. Question: Foam cells develop as a result of which of the following options?
- A. Uptake of LDL in macrophages
- B. Uptake of LDL by LDL-R
- C. Uptake of ox-LDL by scavenger receptors
- D. Uptake of LDL by scavenger receptors
Correct Answer: C
Rationale: Foam cells ox-LDL via scavenger receptors stuff macrophages, not plain LDL or LDL-R. Nurses see this, a chronic plaque birth.

According to Johnson and Chang (2014) the role of the nurse and other health professions in chronic disease is to:
- A. Support the person in managing their condition more effectively
- B. Provide care to manage the disease process
- C. Ensure the patient takes their medications and avoids all risk factors
- D. Decide as a team on the best approach to manage the condition and direct the implementation of this care
Correct Answer: A
Rationale: Nurses in chronic care empower supporting self-management beats just treating, enforcing meds, or dictating plans. It's about patients steering their diabetes or asthma, with pros as guides, not bosses. Care's given, compliance nudged, teams plan, but support's the heart, a chronic win where autonomy rules.
After receiving the hand-off report, which client should the oncology nurse see first?
- A. Client who is afebrile with a heart rate of 108 beats/min
- B. Older client on chemotherapy with mental status changes
- C. Client who is neutropenic and in protective isolation
- D. Client scheduled for radiation therapy today
Correct Answer: B
Rationale: In oncology nursing, prioritizing care is critical due to the complexity of cancer patients' conditions. An older client on chemotherapy with mental status changes is the priority because this could signal sepsis or infection, especially since chemotherapy-induced neutropenia often masks typical signs like fever in the elderly. Mental confusion might be the only early clue, and delayed assessment could lead to rapid deterioration or death. A heart rate of 108 beats/min without fever suggests tachycardia, possibly from dehydration or anxiety, but it's less urgent without other red flags. A neutropenic client in isolation needs monitoring, but no acute change is noted. The client scheduled for radiation has a planned treatment, not an immediate crisis. Assessing the older client first allows the nurse to rule out or address a life-threatening issue, aligning with the principle of prioritizing unstable patients in acute care settings.
What is an important independent risk factor for the development of type 2 diabetes mellitus?
- A. Alcohol use
- B. Ethnicity
- C. Socioeconomic status
- D. All three options above
Correct Answer: B
Rationale: Ethnicity stands tall South Asians, Hispanics outpace Caucasians in type 2 risk, genes and fat patterns at play. Alcohol's murky, socioeconomic status shapes access, not biology nurses see heritage trump these, a chronic marker needing tailored screens.
Which of the following interventions would be best for the child who has developed mucositis as a side effect of chemotherapy?
- A. Using lemon glycerin swabs for oral hygiene.
- B. Keeping the child NPO until all sores are healed.
- C. Having the child swish and swallow viscous lidocaine.
- D. Giving the child pudding for breakfast.
Correct Answer: D
Rationale: Mucositis, a painful chemotherapy side effect, involves inflamed, ulcerated mucous membranes, often in the mouth, complicating eating and hygiene. Offering pudding a soft, bland, cool food is the best intervention, as it minimizes irritation and pain, encouraging nutrition without exacerbating sores. Lemon glycerin swabs are harsh, with citric acid and chemicals worsening discomfort and delaying healing. Keeping the child NPO (nothing by mouth) for weeks until sores heal is impractical and risks malnutrition, as mucositis can persist throughout chemotherapy. Viscous lidocaine might numb pain but is a last resort if the child refuses all intake, not a first-line comfort measure. Pudding supports hydration and calorie intake safely, aligning with nursing's goal to maintain nutrition and comfort in pediatric oncology, reducing mucositis-related distress effectively.
A patient's most recent diagnostic imaging has revealed that his lung cancer has metastasized to his bones and liver. What is the most likely mechanism by which the patient's cancer cells spread?
- A. Hematologic spread
- B. Lymphatic circulation
- C. Invasion
- D. Angiogenesis
Correct Answer: B
Rationale: Lung cancer loves lymphatics its cells hitch rides via nodes, the most common metastasis route, hitting bones and liver downstream. Blood (hematologic) spread happens too, but lymph's king for lung primaries. Invasion's local creep, not distant jumps. Angiogenesis feeds tumors, not moves them. Nurses track this pattern, knowing lymph drainage from lungs seeds those far-off sites, a grim oncology reality shaping staging and prognosis.
