,Section 1: Clotting (Q1-Q10)
Q1. A nurse is caring for a client with disseminated intravascular coagulation (DIC). Which medication should the
nurse anticipate administering to limit clotting?
A. Heparin [CORRECT]
B. Vitamin K
C. Aminocaproic acid
D. Protamine sulfate
Correct Answer: A
Rationale: DIC involves widespread activation of the coagulation cascade, leading to microvascular thrombosis and consumption of
clotting factors. Heparin is administered to limit further clotting by inhibiting thrombin and factor Xa. The ATI concept of Clotting
identifies heparin as a key intervention in DIC to interrupt the coagulation cascade. Vitamin K (B) reverses warfarin and is not used for
DIC. Aminocaproic acid (C) is an antifibrinolytic that would worsen DIC by preventing clot breakdown. Protamine sulfate (D) reverses
heparin and is contraindicated.
Q2. A nurse is preparing to administer a platelet transfusion to a client with thrombocytopenia. Which guideline is
most important for the nurse to follow?
A. Administer the transfusion through a filter over 15 to 30 minutes [CORRECT]
B. Administer the transfusion rapidly over 5 to 10 minutes
C. Use a microdrip tubing without a filter for platelet administration
D. Premedicate the client with diphenhydramine to prevent allergic reactions
Correct Answer: A
Rationale: Platelet transfusions must be administered through a filter to remove clots and aggregates, and the infusion should occur over
15 to 30 minutes to prevent platelet clumping and ensure viability. The ATI concept of Clotting emphasizes this administration guideline.
Rapid infusion (B) can damage platelets. Filters are always required (C is wrong). Premedication (D) is not routinely required for
platelet transfusions unless the client has a history of reactions.
Q3. A client receiving chemotherapy has a platelet count of 50,000/mm3. Which assessment should the nurse
perform daily to evaluate for internal bleeding?
A. Measure abdominal girth [CORRECT]
B. Assess for pedal edema
C. Monitor blood pressure every 4 hours
D. Check deep tendon reflexes
Correct Answer: A
Rationale: A platelet count of 50,000/mm3 indicates thrombocytopenia, which places the client at risk for bleeding. Measuring
abdominal girth daily helps detect internal bleeding, particularly gastrointestinal bleeding, which may present as a gradual increase in
girth due to intra-abdominal hemorrhage. The ATI concept of Clotting identifies this as a key assessment for clients with
thrombocytopenia. Pedal edema (B) indicates fluid retention, not bleeding. Blood pressure monitoring (C) is important but detects
hemorrhagic shock, not early internal bleeding. DTRs (D) assess neurological function, not bleeding.
Q4. A nurse is reviewing the laboratory results of a client with DIC. Which combination of findings supports the
diagnosis of DIC?
A. Decreased platelets, prolonged PT and aPTT, decreased fibrinogen, and elevated D-dimer [CORRECT]
B. Increased platelets, shortened PT and aPTT, elevated fibrinogen, and decreased D-dimer
C. Normal platelets, normal PT and aPTT, normal fibrinogen, and elevated D-dimer
D. Decreased platelets, normal PT and aPTT, elevated fibrinogen, and normal D-dimer
Correct Answer: A
Rationale: DIC is characterized by consumption of clotting factors and platelets, leading to decreased platelets, prolonged PT and aPTT
(due to factor consumption), decreased fibrinogen (consumed during clotting), and elevated D-dimer (evidence of fibrin degradation
from clot breakdown). The ATI concept of Clotting identifies this laboratory pattern as diagnostic for DIC. Increased platelets and
shortened coagulation times (B) suggest a hypercoagulable state, not DIC. Normal values (C) do not support DIC. Elevated fibrinogen
(D) is inconsistent with the consumptive process of DIC.
Q5. A client with atrial fibrillation is prescribed warfarin therapy. Which laboratory test should the nurse monitor
to evaluate the effectiveness of warfarin?
A. International Normalized Ratio (INR) [CORRECT]
B. Activated partial thromboplastin time (aPTT)
C. Prothrombin time (PT) alone
, D. Bleeding time
Correct Answer: A
Rationale: INR is the standardized laboratory test for monitoring warfarin therapy. For atrial fibrillation, the target INR is typically
2.0-3.0. The ATI concept of Clotting identifies INR as the primary monitoring parameter for warfarin. aPTT (B) is used to monitor
heparin therapy, not warfarin. PT alone (C) is less reliable than INR because PT values vary between laboratories. Bleeding time (D)
assesses platelet function, not coagulation factor activity.
Q6. A client who is postoperative following total hip replacement is prescribed enoxaparin. Which nursing action is
most important?
A. Administer the medication subcutaneously at the same time each day [CORRECT]
B. Administer the medication intramuscularly in the vastus lateralis
C. Crush the medication and mix with applesauce for easier swallowing
D. Apply ice to the injection site after administration
Correct Answer: A
Rationale: Enoxaparin is a low molecular weight heparin (LMWH) administered subcutaneously for DVT prophylaxis. It should be given
at the same time each day to maintain therapeutic anticoagulation levels. The ATI concept of Clotting emphasizes that LMWH is given
subcutaneously, never intramuscularly (B) due to the risk of hematoma. It is not given orally (C). Ice application (D) is not a standard
requirement for subcutaneous enoxaparin administration.
Q7. A nurse is caring for a client who has a suspected deep vein thrombosis (DVT) in the left calf. Which finding
should the nurse expect?
A. Left calf swelling, warmth, redness, and a positive Homan sign [CORRECT]
B. Right calf pallor, coolness, and diminished pedal pulse
C. Bilateral leg pitting edema with jugular vein distention
D. Intermittent claudication that worsens with walking and improves with rest
Correct Answer: A
Rationale: DVT typically presents with unilateral leg swelling, warmth, erythema, and a positive Homan sign (pain in the calf on
dorsiflexion of the foot). The ATI concept of Clotting identifies these as classic manifestations of DVT. Pallor and coolness (B) suggest
arterial occlusion, not venous thrombosis. Bilateral edema with JVD (C) suggests right-sided heart failure. Intermittent claudication (D) is
a manifestation of peripheral arterial disease, not DVT.
Q8. A nurse is providing discharge teaching to a client who is starting warfarin therapy. Which statement by the
client indicates a need for further teaching?
A. I will increase my intake of dark green leafy vegetables to improve my nutrition [CORRECT]
B. I will have my INR checked regularly as prescribed by my provider
C. I will avoid taking aspirin or ibuprofen unless prescribed by my provider
D. I will notify my provider if I experience unusual bleeding or bruising
Correct Answer: A
Rationale: Dark green leafy vegetables (spinach, kale, broccoli) are high in vitamin K, which antagonizes the effects of warfarin.
Increasing intake of these foods can decrease warfarin effectiveness and increase the risk of thrombosis. The client should maintain a
consistent diet rather than drastically changing vitamin K intake. The ATI concept of Clotting emphasizes dietary consistency for clients
on warfarin. Regular INR monitoring (B), avoiding NSAIDs (C), and reporting bleeding (D) are all correct statements.
Q9. A client is receiving a continuous heparin infusion for acute pulmonary embolism. Which adverse effect should
the nurse monitor for?
A. Bleeding [CORRECT]
B. Hypertension
C. Bradycardia
D. Hyperreflexia
Correct Answer: A
Rationale: Bleeding is the primary adverse effect of heparin therapy. The ATI concept of Clotting identifies bleeding as the most critical
safety concern for clients receiving anticoagulants. The nurse should monitor for signs of bleeding including hematuria, melena,
ecchymosis, epistaxis, and bleeding from IV sites. Heparin does not cause hypertension (B), bradycardia (C), or hyperreflexia (D).
Q10. A nurse is reviewing the medication profile of a client prescribed warfarin. Which medication interaction
should the nurse identify as increasing the risk of bleeding?
A. Aspirin [CORRECT]
B. Oral contraceptives
C. Phenytoin
D. Cholestyramine
