VERIFIED ANSWERS for PASS GUARANTEED
Question 1: Which anatomical structure is primarily responsible for the production of bile in the
human body?
A. Gallbladder
B. Pancreas
C. Liver
D. Spleen
CORRECT ANSWER: C. Liver
RATIONALE: The liver is the organ responsible for synthesizing bile, which aids in the digestion and
absorption of fats in the small intestine. The gallbladder stores and concentrates bile but does not
produce it. The pancreas produces digestive enzymes and bicarbonate, while the spleen functions in
immune response and blood filtration.
Question 2: A nurse is administering furosemide to a patient with heart failure. Which assessment
finding requires immediate intervention?
A. Blood pressure of 110/70 mmHg
B. Potassium level of 3.2 mEq/L
C. Urine output of 50 mL/hr
D. Weight loss of 1 kg in 24 hours
CORRECT ANSWER: B. Potassium level of 3.2 mEq/L
RATIONALE: Furosemide is a loop diuretic that promotes potassium excretion, placing patients at risk
for hypokalemia. A potassium level of 3.2 mEq/L is below the normal range (3.5-5.0 mEq/L) and can
cause cardiac dysrhythmias, muscle weakness, and fatigue, requiring prompt intervention such as
potassium supplementation.
Question 3: During a pediatric assessment, which developmental milestone is expected in a 9-month-
old infant?
A. Walking independently
B. Saying two-word phrases
C. Pincer grasp development
D. Jumping with both feet
CORRECT ANSWER: C. Pincer grasp development
,RATIONALE: By 9 months of age, infants typically develop the pincer grasp, using the thumb and
forefinger to pick up small objects. Walking independently usually occurs around 12-15 months, two-
word phrases emerge around 18-24 months, and jumping with both feet develops around 2-3 years of
age.
Question 4: Which pathophysiological process is primarily involved in the development of type 2
diabetes mellitus?
A. Autoimmune destruction of pancreatic beta cells
B. Insulin resistance combined with relative insulin deficiency
C. Complete absence of insulin production
D. Excessive glucagon secretion from alpha cells
CORRECT ANSWER: B. Insulin resistance combined with relative insulin deficiency
RATIONALE: Type 2 diabetes mellitus is characterized by peripheral insulin resistance, where cells do
not respond effectively to insulin, combined with inadequate insulin secretion from pancreatic beta cells
to compensate. Option A describes type 1 diabetes, option C represents advanced type 1 diabetes, and
option D is not the primary mechanism in type 2 diabetes.
Question 5: A patient receiving warfarin therapy has an INR of 5.2. Which action should the nurse
prioritize?
A. Administer the next scheduled dose of warfarin
B. Prepare to administer vitamin K as prescribed
C. Encourage increased intake of leafy green vegetables
D. Document the finding and continue monitoring
CORRECT ANSWER: B. Prepare to administer vitamin K as prescribed
RATIONALE: An INR of 5.2 is significantly above the therapeutic range (typically 2.0-3.0 for most
indications), indicating excessive anticoagulation and high risk for bleeding. Vitamin K is the antidote for
warfarin reversal and should be administered per protocol. Administering more warfarin or increasing
vitamin K-rich foods would be contraindicated, and simply documenting without intervention could
result in serious harm.
Question 6: Which microorganism is most commonly associated with healthcare-associated urinary
tract infections?
A. Streptococcus pneumoniae
B. Escherichia coli
C. Clostridium difficile
D. Mycobacterium tuberculosis
CORRECT ANSWER: B. Escherichia coli
RATIONALE: Escherichia coli is the most frequent causative organism in both community-acquired and
healthcare-associated urinary tract infections, accounting for approximately 75-90% of cases. It
originates from the patient's gastrointestinal flora and ascends the urinary tract. Streptococcus
,pneumoniae causes respiratory infections, Clostridium difficile causes antibiotic-associated colitis, and
Mycobacterium tuberculosis causes tuberculosis.
Question 7: In the context of evidence-based practice, what does the acronym PICO represent?
A. Patient, Intervention, Comparison, Outcome
B. Problem, Implementation, Control, Observation
C. Population, Indicator, Criterion, Objective
D. Procedure, Intervention, Calculation, Outcome
CORRECT ANSWER: A. Patient, Intervention, Comparison, Outcome
RATIONALE: PICO is a foundational framework used to formulate clinical questions in evidence-based
practice. It stands for Patient/Population, Intervention, Comparison, and Outcome. This structure helps
clinicians develop focused, answerable questions that guide literature searches and critical appraisal of
research evidence.
Question 8: A pregnant patient at 32 weeks gestation reports persistent headache and visual
disturbances. Which condition should the nurse suspect?
A. Gestational diabetes
B. Preeclampsia
C. Placenta previa
D. Hyperemesis gravidarum
CORRECT ANSWER: B. Preeclampsia
RATIONALE: Persistent headache and visual disturbances (such as blurred vision or scotomata) are
classic neurological symptoms of preeclampsia, a hypertensive disorder of pregnancy that typically
occurs after 20 weeks gestation. These symptoms, especially when accompanied by hypertension and
proteinuria, require immediate evaluation. Gestational diabetes presents with hyperglycemia, placenta
previa with painless vaginal bleeding, and hyperemesis gravidarum with severe nausea and vomiting
early in pregnancy.
Question 9: Which ethical principle obligates healthcare providers to avoid causing harm to patients?
A. Autonomy
B. Beneficence
C. Nonmaleficence
D. Justice
CORRECT ANSWER: C. Nonmaleficence
RATIONALE: Nonmaleficence is the ethical principle that requires healthcare providers to refrain from
actions that cause harm or injury to patients. This principle is often summarized as "first, do no harm."
Autonomy respects patient self-determination, beneficence promotes doing good, and justice addresses
fairness in resource allocation and treatment.
Question 10: A patient with chronic obstructive pulmonary disease (COPD) is prescribed oxygen
therapy. Why should the nurse administer oxygen at low flow rates (1-2 L/min)?
, A. To prevent oxygen toxicity in the lungs
B. To avoid suppressing the hypoxic drive to breathe
C. To reduce the risk of fire in the patient's room
D. To minimize nasal mucosa irritation
CORRECT ANSWER: B. To avoid suppressing the hypoxic drive to breathe
RATIONALE: Patients with chronic COPD may rely on hypoxic drive (low oxygen levels) rather than
hypercapnic drive (high carbon dioxide levels) to stimulate respiration. Administering high
concentrations of oxygen can suppress this hypoxic drive, potentially leading to respiratory depression
and CO2 retention. While oxygen toxicity and mucosal irritation are concerns with prolonged high-flow
oxygen, the primary RATIONALE for low-flow administration in COPD is preserving respiratory drive.
Question 11: Which laboratory value is most indicative of acute myocardial infarction when elevated
within 3-6 hours of symptom onset?
A. Creatine kinase-MB (CK-MB)
B. Troponin I
C. Myoglobin
D. Lactate dehydrogenase (LDH)
CORRECT ANSWER: B. Troponin I
RATIONALE: Cardiac troponins (I and T) are the most specific and sensitive biomarkers for myocardial
injury. Troponin I begins to rise within 3-6 hours after myocardial infarction, peaks at 12-24 hours, and
remains elevated for 7-10 days, making it ideal for early and late diagnosis. CK-MB rises slightly later and
is less specific, myoglobin rises early but lacks cardiac specificity, and LDH is a late marker no longer
routinely used for MI diagnosis.
Question 12: During a mental status examination, a patient demonstrates flight of ideas. This finding
is most characteristic of which condition?
A. Major depressive disorder
B. Schizophrenia
C. Bipolar disorder, manic episode
D. Generalized anxiety disorder
CORRECT ANSWER: C. Bipolar disorder, manic episode
RATIONALE: Flight of ideas, characterized by rapid, continuous speech with abrupt shifts between
loosely connected topics, is a hallmark symptom of the manic phase of bipolar disorder. It reflects
accelerated thought processes and pressured speech. Major depressive disorder typically features
psychomotor retardation and slowed thinking, schizophrenia may include disorganized speech but not
specifically flight of ideas, and generalized anxiety disorder involves excessive worry without this specific
thought pattern.
Question 13: Which nursing intervention is most effective in preventing pressure injuries in an
immobile patient?
