Which of the following statements regarding factors leading to obesity is FALSE?
- A. The factors known to cause obesity are complex and multiple
- B. Twin, family and adoption studies show that the rate of heritability of BMI is high, ranging from 40% to 70% demonstrating a major genetic component
- C. More recent studies have identified a potential role for the microbial content of the skin
- D. Emotional factors are well-known to be potent modulators of appetite
Correct Answer: C
Rationale: Obesity's mess genes, emotions, drugs stack up; gut microbes, not skin, tip scales. Nurses sift this chronic cause pile, nixing dermal fluff.

What is the most influential source of self-efficacy?
- A. Mastery
- B. Affective states
- C. Verbal persuasion
- D. Vicarious experience
Correct Answer: A
Rationale: Self-efficacy's backbone is mastery past wins breed belief, a nurse's gold for chronic self-care push. Watching others, pep talks, or mood sway less; doing it trumps all, a confidence anchor in illness battles.
A patient with leukemia is considering whether to have hematopoietic stem cell transplantation (HSCT). The nurse will include which information in the patient's teaching plan?
- A. Donor bone marrow is transplanted through a sternal or hip incision.
- B. Hospitalization is required for several weeks after the stem cell transplant.
- C. The transplant procedure takes place in a sterile operating room to minimize the risk for infection.
- D. Transplant of the donated cells can be very painful because of the nerves in the tissue lining the bone.
Correct Answer: B
Rationale: HSCT for leukemia means 2-4 weeks in hospital engraftment's slow, and infection risk's sky-high in isolation. No incision it's IV. No OR it's bedside. Pain's minimal no bone nerves hit. Nurses in oncology stress this long haul, sterile stay, not surgical drama, prepping patients for the real grind.
In CSF of a patient with viral meningitis, the most prominent white cell is usually?
- A. monocytes
- B. lymphocytes
- C. polymorphs
- D. eosinophils
Correct Answer: B
Rationale: Viral meningitis pulls lymphocytes immune sentinels flood CSF, not polymorphs of bacterial wars, monocytes lagging, eosinophils for worms, or vague granulocytes. It's the chronic viral signature nurses spot this shift, ruling out pus-filled bacterial chaos with one cell peek.
A client hospitalized for chemotherapy has a hemoglobin of $6.1 mg/dL. What medication should the nurse prepare to administer?
- A. Epoetin alfa (Epogen)
- B. Filgrastim (Neupogen)
- C. Mesna (Mesnex)
- D. Oprelvekin (Neumega)
Correct Answer: A
Rationale: A hemoglobin of 6.1 mg/dL (normal 12-16 g/dL for women, 13-18 g/dL for men) indicates severe anemia, often from chemotherapy suppressing bone marrow red cell production. The nurse should prepare epoetin alfa (Epogen), a synthetic erythropoietin that stimulates red blood cell production, addressing anemia directly. Filgrastim (Neupogen) boosts white cells for neutropenia, not hemoglobin. Mesna (Mesnex) protects the bladder from chemotherapy toxicity, irrelevant here. Oprelvekin (Neumega) increases platelets, not red cells. Administering epoetin alfa corrects the anemia, improving oxygen delivery and reducing symptoms like fatigue and dyspnea, a critical intervention in oncology to support the client's recovery and quality of life during treatment.
The best way to prevent chronic complications of diabetes is to:
- A. Take medications as prescribed and remove sugar from the diet completely.
- B. Check feet daily for cuts, long toe nails and infections between the toes.
- C. Maintain a BGL that is as close to normal as possible.
- D. Undertake daily exercise to burn up the excess glucose in the system.
Correct Answer: C
Rationale: Preventing diabetes complications (e.g., neuropathy, retinopathy) hinges on glycemic control. Medications and sugar elimination help, but total sugar removal is impractical carbohydrates are broader, and control, not absence, matters. Daily foot checks prevent ulcers but address consequences, not root causes. Maintaining blood glucose levels (BGL) near normal (e.g., HbA1c <7%) via diet, exercise, and drugs prevents microvascular (kidney, eye) and macrovascular (heart) damage, per ADA guidelines. Exercise burns glucose, aiding control, but isn't singularly best' it's part of a triad. Tight BGL management reduces oxidative stress, glycation, and vascular injury, evidenced by trials (e.g., DCCT), making it the cornerstone strategy over isolated tactics, ensuring long-term organ protection.
