Nokea
Which of the following medication is recommended for all patients with NAFLD in improving liver histology?
- A. Statins
- B. Aspirins
- C. Ursodeoxycholic acid
- D. None of the above
Correct Answer: D
Rationale: NAFLD no med fits all; statins, aspirin, ursodiol, E lack universal proof. Nurses skip this chronic blanket pill.

In assigning patients with alterations related to gastrointestinal (GI) cancer, which would be the most appropriate nursing care tasks to assign to the LPN/LVN, under supervision of the team leader RN?
- A. A patient with severe anemia secondary to GI bleeding
- B. A patient who needs enemas and antibiotics to control GI bacteria
- C. A patient who needs pre-op teaching for bowel resection surgery
- D. A patient who needs central line insertion for chemotherapy
Correct Answer: B
Rationale: LPN/LVNs operate under RN supervision, handling tasks within their scope like administering enemas and antibiotics to control GI bacteria in a cancer patient, a straightforward, protocol-driven intervention to reduce infection risk before procedures. Severe anemia from GI bleeding demands RN assessment for transfusion or instability, beyond LPN scope. Pre-op teaching for bowel resection requires detailed education and evaluation, an RN duty to ensure comprehension. Central line insertion for chemotherapy involves advanced skills and risk management, reserved for RNs or specialized staff. Enemas and antibiotics fit LPN/LVN training, optimizing team efficiency while keeping complex care with RNs, aligning with safe delegation principles in GI cancer management.
Spirometry is used to determine the severity of COPD and to monitor disease progression. This test measures
- A. The ratio of volume of air the patient can forcibly exhale in 1 second and forced vital capacity.
- B. The ratio of residual volume when patient has fully exhaled and forced vital capacity.
- C. The ratio of forced vital capacity and volume of air the patient can forcibly exhale in 6 seconds.
- D. The ratio of respiratory effort and respiratory rate.
Correct Answer: A
Rationale: Spirometry is the gold standard for COPD diagnosis and staging, measuring airflow obstruction. The ratio of forced expiratory volume in 1 second (FEVâ‚) to forced vital capacity (FVC) FEVâ‚/FVC quantifies limitation; a value <0.7 post-bronchodilator confirms COPD, with FEVâ‚ percentage grading severity (e.g., GOLD stages). Residual volume (RV) to FVC isn't standard in basic spirometry RV requires advanced testing (e.g., plethysmography) and reflects air trapping, not routine staging. FVC versus a 6-second exhale (FEV₆) approximates in some settings but isn't the clinical norm for COPD. Respiratory effort and rate aren't spirometric; they're observational. FEVâ‚/FVC's precision, per Deravin and Anderson (2019), tracks obstruction progression and guides therapy, making it foundational for assessing COPD's irreversible nature.
Early Goal Directed Therapy in severe sepsis and septic shock (Rivers et al) does NOT recommend:
- A. hydrocortisone 100 mg QID
- B. maintaining mixed venous oxygen saturation measurement >70%
- C. maintaining CVP between 8-12 mmHg
- D. using inotropes to keep MAP >65 mmHg<90 mmHg
Correct Answer: A
Rationale: Rivers' sepsis hydrocortisone's out, SvO2, CVP, MAP, dobutamine hold. Nurses skip this chronic steroid sidestep.
People with metabolic syndrome have an increased risk of which of the following disorders, besides type 2 diabetes mellitus?
- A. Hypertension, infections
- B. Myocardial infarction, hypertension
- C. Myocardial infarction, infections
- D. Myocardial infarction, liver cirrhosis
Correct Answer: B
Rationale: Metabolic syndrome hikes heart attacks, hypertension vascular hits, not infections or cirrhosis extras. Nurses track this, a chronic CV duo.
The following are true about education for insulin therapy EXCEPT:
- A. It can only be done by nurses
- B. Different subjects to be covered at different stages of insulin therapy
- C. Improves adherence to insulin therapy
- D. It takes time
Correct Answer: A
Rationale: Insulin teaching docs, educators join nurses, staged topics boost sticking, time and prep pay off; nurse-only's bunk. Nurses weave this chronic learning web, not solo.
