you for the VATI PN Comprehensive Predictor assessment using the exact NCLEX-
style format with detailed rationales for every answer.

the provided correct answer and rationale to identify knowledge gaps and
strengthen clinical reasoning skills across all nursing competencies.
QUESTION 1
A nurse is caring for a client who is taking metformin for type 2 diabetes.
Which of the following findings would indicate the client is experiencing a
therapeutic effect of this medication?
A) Blood glucose levels are consistently below 60 mg/dL
B) Fasting blood glucose levels range from 90-130 mg/dL
C) The client reports significant weight gain
D) The client experiences frequent episodes of hypoglycemia
E) Hemoglobin A1c increases to 8.5%
✓ CORRECT ANSWER: B) Fasting blood glucose levels range from 90-130 mg/dL
RATIONALE: Metformin's therapeutic effect is demonstrated when fasting blood
glucose levels are maintained within the normal range of 90-130 mg/dL, indicating
good glycemic control. Levels below 60 mg/dL would indicate hypoglycemia
(adverse effect). Weight gain is not typical of metformin therapy. Frequent
,hypoglycemia is not expected with metformin monotherapy. An A1c of 8.5% would
indicate poor glycemic control, not therapeutic effect.
QUESTION 2
A nurse is assessing a client with a new diagnosis of heart failure. Which of
the following findings should the nurse recognize as characteristic of left-
sided heart failure?
A) Jugular venous distention and peripheral edema
B) Orthopnea and crackles in the lungs
C) Hepatomegaly and ascites
D) Fatigue and weakness only
E) Increased blood pressure throughout the assessment
✓ CORRECT ANSWER: B) Orthopnea and crackles in the lungs
RATIONALE: Left-sided heart failure causes pulmonary congestion, resulting in
orthopnea (shortness of breath when lying flat) and crackles heard on lung
auscultation. Jugular venous distention, peripheral edema, hepatomegaly, and
ascites are characteristic of right-sided heart failure. While fatigue may occur, it is
not specific to the type of heart failure. Increased blood pressure would not be
expected as a characteristic finding of heart failure.
QUESTION 3
A nurse is preparing to administer an intramuscular injection to a client.
Which of the following describes the correct angle of insertion for an IM
injection?
A) 15 degrees
,B) 45 degrees
C) 60 degrees
D) 90 degrees
E) 120 degrees
✓ CORRECT ANSWER: D) 90 degrees
RATIONALE: An intramuscular injection should be administered at a 90-degree
angle (perpendicular) to the skin to ensure the medication reaches the muscle
tissue. A 15-degree angle is too shallow and would result in subcutaneous injection.
Angles of 45, 60, and 120 degrees are incorrect and would not properly deliver
medication into the muscle.
QUESTION 4
A client is admitted with a diagnosis of pneumonia. The nurse notes the client
has a productive cough with greenish sputum, fever of 39.2°C (102.6°F), and
difficulty breathing. Which of the following nursing interventions should be
the priority?
A) Administer antipyretics to reduce fever
B) Position the client upright and apply oxygen therapy
C) Encourage fluid intake to thin secretions
D) Obtain a sputum culture specimen
E) Administer antibiotics immediately
✓ CORRECT ANSWER: B) Position the client upright and apply oxygen therapy
RATIONALE: The priority nursing intervention for a client with pneumonia who is
experiencing difficulty breathing is to position the client upright (semi-Fowler's or
high Fowler's) to promote lung expansion and apply oxygen therapy to maintain
adequate oxygenation and tissue perfusion. While other interventions are
, important, addressing the immediate respiratory compromise is the priority.
Antibiotics must be prescribed by a physician, not independently administered by a
nurse.
QUESTION 5
A nurse is reviewing laboratory values for a client receiving warfarin therapy
for atrial fibrillation. Which of the following INR values indicates the client is
at therapeutic range?
A) INR of 0.8
B) INR of 1.5
C) INR of 2.5
D) INR of 4.2
E) INR of 5.0
✓ CORRECT ANSWER: C) INR of 2.5
RATIONALE: For most clients taking warfarin (such as those with atrial fibrillation),
the therapeutic INR range is 2.0-3.0. An INR of 2.5 falls within this therapeutic
range. An INR of 0.8 indicates inadequate anticoagulation. An INR of 1.5 is below
therapeutic range. INR values of 4.2 and 5.0 indicate over-anticoagulation and
increased bleeding risk.
QUESTION 6
A nurse is caring for a newborn with suspected jaundice. Which of the
following findings would the nurse expect to observe?
A) Pale skin with blue-tinged extremities
