The following blood values are found in a patient: total cholesterol: 9.2 mmol/L (strongly elevated) and triglycerides: 1.7 mmol/L (normal). Question: Which lipid particle is most likely to cause this abnormal lipid spectrum?
- A. The chylomicron particle
- B. The IDL particle
- C. The LDL particle
- D. The VLDL particle
Correct Answer: C
Rationale: Sky-high cholesterol, normal triglycerides LDL's the cholesterol hog, not chylomicrons, IDL, or VLDL's triglyceride tilt. Nurses peg this, a chronic heart risk spike.

When caring for a patient who is pancytopenic, which action by unlicensed assistive personnel (UAP) indicates a need for the nurse to intervene?
- A. The UAP assists the patient to use dental floss after eating.
- B. The UAP adds baking soda to the patient's saline oral rinses.
- C. The UAP puts fluoride toothpaste on the patient's toothbrush.
- D. The UAP has the patient rinse after meals with a saline solution.
Correct Answer: A
Rationale: Pancytopenia low everything means flossing risks bleeding and infection in a mouth with no platelets or immunity; baking soda , fluoride , and saline are safe. Nurses in oncology stop this UAP need soft-brush guidance, not floss, to protect fragile mucosa.
Which of the following condition has low risk of progression to liver cirrhosis:
- A. Hepatic steatosis
- B. Hepatic steatohepatitis
- C. Hepatic steatohepatitis with fibrosis
- D. Chronic hepatitis
Correct Answer: A
Rationale: Steatosis fat sits, low cirrhosis odds; steatohepatitis, fibrosis, chronic, booze burn scar. Nurses mark this chronic liver lite.
A new nurse has been assigned a client who is in the hospital to receive iodine-131 treatment. Which action by the nurse is best?
- A. Ensure the client is placed in protective isolation.
- B. Hand off a pregnant client to another nurse.
- C. No special action is necessary to care for this client.
- D. Read the policy on handling radioactive excreta.
Correct Answer: D
Rationale: Iodine-131 is a radioactive isotope used in treatments like thyroid cancer therapy, and it is excreted through body fluids such as urine and sweat. This poses a radiation hazard to healthcare workers and others if not managed properly. The best action for a new nurse is to read the facility's policy on handling radioactive excreta, as this ensures adherence to safety protocols specific to the institution, protecting both the nurse and the client. Protective isolation is not typically required for iodine-131 patients; instead, radiation precautions limit exposure to others. Handing off a pregnant client might be relevant in other contexts but isn't the priority here unless the nurse is pregnant herself, which isn't specified. Assuming no special action is needed is dangerous given the radioactive nature of the treatment. Reviewing the policy equips the nurse with the knowledge to manage waste, maintain a safe distance, and use protective equipment, aligning with radiation safety principles critical in oncology nursing.
Heart failure with preserved ejection fraction is caused by:
- A. Ventricular hypertrophy reducing contractility of muscles
- B. Decreased perfusion of the myocardium
- C. Dilated cardiomyopathy
- D. Impaired ventricular relaxation resulting in the lack of ability of ventricles to fill with blood
Correct Answer: D
Rationale: HFpEF stiff ventricles won't relax, slashing fill-up, not pump-out. Hypertrophy aids, doesn't cause; perfusion dips hurt supply; dilated's HFrEF. Nurses target this, a chronic fill flaw.
Proven treatment for patients with noncirrhosis from NAFLD include the following except:
- A. Liver transplant
- B. Bariatric surgery
- C. Vitamin E
- D. Weight loss
Correct Answer: A
Rationale: Noncirrhotic NAFLD bends to weight loss, bariatric cuts, and Vitamin E's antioxidant punch proven aids. Transplant's endgame for cirrhosis, not here. Metformin flops for fat, despite diabetes use. Clinicians skip this organ swap, leaning on lifestyle and pills, a chronic fix before scars hit.
