this study guide eliminates guesswork and guarantees maximum retention
to secure an A on your next exam.
Question 1
A patient with chronic kidney disease (CKD) presents with severe fatigue
and a hemoglobin level of 7.8 g/dL. The nurse expects to administer
Epoetin alfa. Which underlying physiological defect is this medication
correcting?
• A) Deficient dietary iron absorption in the small intestine.
• B) Premature destruction of red blood cells in the spleen.
• C) Impaired renal synthesis of erythropoietin due to damaged tissue.
• D) Lack of intrinsic factor production in the gastric mucosa.
,Answer: C
Rationale: Chronic kidney disease damages the renal peritubular
cells, which are responsible for producing erythropoietin. Without this
hormone, the bone marrow is not stimulated to produce red blood
cells, leading to anemia of chronic disease. Epoetin alfa is a synthetic
form of erythropoietin that directly replaces this deficiency.
Question 2
The nurse is preparing to administer a subcutaneous injection of Heparin to
a patient on bed rest. What is the primary mechanism of action of Heparin?
• A) It binds to antithrombin III, inactivating thrombin and factor Xa.
• B) It suppresses the synthesis of vitamin K-dependent clotting
factors.
• C) It directly lyses existing fibrin strands within an established clot.
• D) It irreversibly blocks COX-1 receptors to prevent platelet
aggregation.
Answer: A
Rationale: Heparin works rapidly by accelerating the action of
antithrombin III, which neutralizes thrombin and factor Xa, thereby
preventing the conversion of fibrinogen to fibrin. It does not dissolve
existing clots but stops new ones from forming or growing.
Question 3
An adult patient with chronic asthma is prescribed an Albuterol inhaler and
a Beclomethasone inhaler. Which instruction is vital for the nurse to include
in the patient's education?
• A) Use the Beclomethasone inhaler first to reduce inflammation
before using the Albuterol.
, • B) Use the Albuterol inhaler first, wait 5 minutes, and then use the
Beclomethasone inhaler.
• C) Rinse the mouth thoroughly with water only after using the
Albuterol inhaler.
• D) Combine both medications into a single nebulizer chamber to save
time.
Answer: B
Rationale: Albuterol is a rapid-acting beta-2 agonist (bronchodilator).
Using it first opens the airways, allowing the inhaled corticosteroid
(Beclomethasone) to penetrate deeper into the pulmonary tissue. The
patient must also rinse their mouth after the corticosteroid to prevent
oral candidiasis (thrush).
Question 4
A patient is admitted to the emergency department with a confirmed acute
ischemic stroke. The medical team plans to infuse alteplase (tPA). Which
assessment finding is an absolute contraindication for this therapy?
• A) The patient's blood pressure is currently 135/85 mmHg.
• B) The patient had a minor outpatient dental cleaning 2 days ago.
• C) The patient experienced a major ischemic stroke 2 months ago.
• D) The patient's symptoms began exactly 2 hours prior to arrival.
Answer: C
Rationale: A history of a major ischemic stroke, serious head trauma,
or intracranial surgery within the past 3 months is an absolute
contraindication for thrombolytic therapy due to the extreme risk of
severe intracranial hemorrhage. Symptoms presenting under 3 to 4.5
hours are actually within the appropriate window for tPA.
Question 5
, A patient is prescribed oral Ferrous Sulfate for iron deficiency anemia. To
maximize absorption, the nurse should instruct the patient to take this
medication with which liquid?
• A) A glass of whole milk.
• B) Calcium-fortified orange juice.
• C) Regular orange juice or water.
• D) Hot green tea.
Answer: C
Rationale: Iron is best absorbed in an acidic environment. Vitamin C
(ascorbic acid) found in regular orange juice enhances iron
absorption. Calcium (found in milk or calcium-fortified juice) and
tannins (found in tea) bind to iron and significantly decrease its GI
absorption.
Question 6
A patient taking Warfarin for atrial fibrillation presents with a dangerously
high International Normalized Ratio (INR) of 8.5 and reports blood in their
urine. Which antidote should the nurse prepare to administer?
• A) Protamine sulfate.
• B) Vitamin K (Phytonadione).
• C) Aminocaproic acid.
• D) Deferoxamine.
Answer: B
Rationale: Vitamin K is the specific antidote used to reverse the
anticoagulant effects of Warfarin. Protamine sulfate reverses Heparin.
Aminocaproic acid is an antifibrinolytic used for excessive bleeding
from thrombolytics, and Deferoxamine treats iron toxicity.
