ANSWERS WITH DETAILED RATIONALES
This premium, high-yield practice bank features
comprehensive multiple-choice questions meticulously
aligned with the 2026 ATI PN Adult Medical Surgical
Proctored Exam specifications. Each question delivers
immediate answer verification paired with detailed, bold-
italicized rationales to reinforce critical clinical judgment and
nursing priorities. It serves as an essential, self-contained
study tool designed to maximize test scores and streamline
final exam preparation for practical nursing students.
1. A nurse is reinforcing teaching with a client who has
chronic kidney disease (CKD) and a new prescription for
epoetin alfa. Which of the following statements by the client
indicates an understanding of the teaching?
A. "This medication will help increase my white blood cell count to
fight infections."
B. "I should expect my energy levels to improve as my red blood
cell count increases."
C. "I will take this pill twice daily with breakfast and dinner."
D. "I need to limit my intake of dietary iron while taking this
medication."
Answer: B
,Rationale: Epoetin alfa stimulates the bone marrow to
produce red blood cells, which reverses the anemia
associated with chronic kidney disease, thereby improving
oxygen oxygenation and overall energy levels. It is
administered via subcutaneous or intravenous injection, not
orally. Clients typically require iron supplements rather than
restriction to support red blood cell production.
2. A nurse is collecting data from a client who is 12 hr
postoperative following a subtotal thyroidectomy. Which of
the following findings is the priority for the nurse to report to
the charge nurse?
A. Incisional pain rated at 6 on a scale of 0 to 10
B. Weak, husky voice when speaking
C. Laryngeal stridor and harsh, high-pitched respirations
D. Small amount of serosanguineous drainage on the dressing
Answer: C
Rationale: Laryngeal stridor indicates acute airway
obstruction, which can be caused by swelling, laryngeal
nerve damage, or tetany from accidental removal of the
parathyroid glands. This is a life-threatening emergency that
requires immediate intervention using the airway, breathing,
circulation (ABC) priority framework. Pain, a husky voice,
and minor serosanguineous drainage are common, expected
findings post-surgery.
3. A nurse is checking the laboratory values of a client who is
receiving a continuous intravenous heparin infusion for a
deep vein thrombosis (DVT). Which of the following
laboratory values indicates that the therapy is effective?
,A. Prothrombin time (PT) of 12 seconds
B. Activated partial thromboplastin time (aPTT) of 65 seconds
C. International Normalized Ratio (INR) of 3.0
D. Platelet count of 95,000/mm³
Answer: B
Rationale: Heparin efficacy is measured using the activated
partial thromboplastin time (aPTT). A therapeutic range is
typically 1.5 to 2.5 times the normal control value (which
generally translates to a therapeutic target of roughly 60 to
80 seconds). PT and INR are used to monitor warfarin
therapy, not heparin. A platelet count of 95,000/mm³ indicates
thrombocytopenia, which is an adverse effect of heparin
(heparin-induced thrombocytopenia).
4. A nurse is reinforcing discharge teaching with a client who
has a new diagnosis of Type 1 diabetes mellitus. Which of
the following instructions regarding injection site rotation
should the nurse include?
A. Rotate sites between different anatomical regions with every
single injection.
B. Inject insulin into the same exact spot for one week before
moving to a new area.
C. Ensure injections within one chosen anatomical region are
spaced 1 inch apart.
D. Avoid using the abdomen as an injection site because
absorption is too slow.
Answer: C
Rationale: Injections within one anatomical region (such as
the abdomen) should be spaced about 1 inch apart to ensure
consistent absorption and prevent lipodystrophy (tissue
, hypertrophy or atrophy). Rotating between entirely different
body regions with every injection causes unpredictable
blood glucose fluctuations because absorption rates vary
between the abdomen, arms, and thighs. The abdomen has
the fastest and most reliable absorption rate.
5. A nurse is reviewing the arterial blood gas (ABG) results of
a client who has been vomiting persistently for 24 hours. The
results are: pH 7.50, PaCO₂ 42 mmHg, HCO₃⁻ 32 mEq/L. The
nurse should interpret these findings as which of the
following acid-base imbalances?
A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis
Answer: D
Rationale: A pH greater than 7.45 indicates alkalosis. The
HCO₃⁻ is elevated above the normal reference range (22-26
mEq/L), while the PaCO₂ remains within its normal range (35-
45 mmHg). This signifies a metabolic alkalosis, which occurs
frequently with persistent vomiting or gastric suctioning due
to the loss of hydrochloric acid from the stomach.
6. A nurse is reinforcing teaching with a client who has a new
prescription for sublingual nitroglycerin tablets for stable
angina. Which of the following instructions should the nurse
provide?
A. Swallow the tablet whole with a full glass of water.
B. Place one tablet under the tongue every 5 minutes for up to 3
doses if chest pain occurs.
