Nursing Practice: Anticoagulation, Respiratory, and Immune
Function
1. A patient at risk for venous thromboembolism (VTE) is being discharged with a
prescription for low-molecular-weight heparin. What essential instruction should
the nurse include?
A) "You will need to have your aPTT levels monitored every two weeks."
B) "Contact your doctor immediately if you notice your stools are dark and tarry."
C) "A permanent IV line will be required to give yourself this medication."
D) "Be sure to massage the area after you inject the heparin."
RATIONALE: Like all anticoagulants, low-molecular-weight heparin increases the
danger of internal bleeding. Patients must be taught to recognize and report clinical
signs of hemorrhage, such as black stools, bleeding gums, or easy bruising. Unlike IV
heparin, this version is given subcutaneously and does not require aPTT monitoring.
Massaging the site is contraindicated as it speeds up absorption and can cause
localized tissue damage.
2. What is the most critical physiological goal for a patient currently being treated
for pneumonia?
A) Maintaining an oxygen saturation (SaO2) of at least 95%.
B) Successfully walking 20 feet three separate times a day.
C) Ensuring the patient does not exhibit cyanosis (blue-tinted skin).
D) Maintaining a clear mental status without confusion.
, RATIONALE: An SaO2 of 95% or higher is a measurable and direct indicator that the
patient is receiving sufficient oxygenation. While confusion and cyanosis are important
assessment data points, they are subjective or secondary indicators. Physical activity is
important but does not take priority over basic oxygenation needs in acute pneumonia.
3. During a cardiac assessment, which statement by the patient would most likely
lead the nurse to suspect right-sided heart failure?
A) "I find I need four pillows behind me to sleep comfortably."
B) "I am frequently woken up at night by a persistent cough."
C) "I’ve noticed that my shoes have been feeling much tighter lately."
D) "I am having a lot of trouble catching my breath during the day."
RATIONALE: Right-sided heart failure leads to systemic congestion, causing fluid to
pool in the extremities and resulting in peripheral edema (swelling of the feet and
ankles). Respiratory symptoms, such as the need to sleep upright (orthopnea),
coughing, and shortness of breath (dyspnea), are typically associated with left-sided
heart failure.
4. A nurse is managing a patient with Crohn’s disease who has known colonic
strictures. Which finding requires an immediate consultation with the physician?
A) Finding small traces of blood in the patient's stool.
B) Observing a noticeably distended or swollen abdomen.
C) A slight temperature elevation to 100.0° F (37.8° C).
D) The patient reporting crampy discomfort in the lower abdomen.
RATIONALE: Strictures significantly increase the risk of a complete bowel obstruction.
A distended abdomen is a major warning sign that the large intestine may be blocked.
While minor bleeding, low-grade fever, and cramping are common for Crohn's, an
obstruction is an emergency that must be reported right away.
5. Based on the instructor’s lectures, which football team do they support?
A) "I am not a fan of football."
B) The Notre Dame Fighting Irish.
C) THE OHIO STATE BUCKEYES (GO BUCKS!)
, D) The Michigan Wolverines (that team up north).
RATIONALE: Per the instructor's first-day orientation, they are a dedicated Buckeyes
fan.
6. A patient is on heparin for a VTE. If their pre-treatment aPTT was 30 seconds,
which result indicates the medication is at a therapeutic level?
A) 30 seconds
B) 150 seconds
C) 60 seconds
D) 15 seconds
RATIONALE: A therapeutic response to heparin generally requires the aPTT to be 1.5
to 2.5 times the baseline (control) value. Given a baseline of 30 seconds, 60 seconds is
exactly 2.0 times the control, fitting perfectly within the desired range.
7. A patient is heading home after a splenectomy. What immune-related
information is most important for their discharge plan?
A) Restricting all social contact with the general public.
B) The requirement to wear a face mask whenever they are outside.
C) An academic understanding of the inflammatory response.
D) Mastering fundamental infection control and hygiene practices.
RATIONALE: Since the spleen is a major immune organ, its removal leaves the patient
more vulnerable to infections. The most practical and effective way for these patients to
stay healthy is by following rigorous, basic infection control (like handwashing). They do
not need to wear masks or isolate themselves if they use proper hygiene.
8. An infected patient has a high fever. Which assessments must the nurse
prioritize? (Select all that apply.)
A) Skin turgor
B) Quality of the pulse
C) Blood pressure
D) Bowel sounds
, E) Respiratory effort
F) Mental status
RATIONALE: High fevers often cause significant fluid loss through sweating, leading to
dehydration. The nurse must monitor blood pressure, pulse, and skin turgor to track the
patient's hydration status. Mental status is also a priority because fluid loss and high
temperatures can cause acute confusion, especially in geriatric patients.
9. A provider orders oral warfarin (Coumadin) for a patient while they are still on
an IV heparin drip. What is the nurse's best course of action?
A) Stop the heparin infusion before giving the first warfarin dose.
B) Question the order with the nursing supervisor.
C) Give both medications as they were prescribed.
D) Hold the warfarin until the patient finishes the heparin course.
RATIONALE: This is standard "bridge therapy." Because warfarin takes several days to
build up a therapeutic level in the blood, the patient must stay on the fast-acting heparin
until the warfarin (measured by INR) is effective. Once the warfarin is therapeutic, the
heparin is discontinued.
10. Why are people with low socioeconomic status at a higher statistical risk for
infections? (Select all that apply.)
A) High costs associated with prescriptions
B) Lack of access to proper nutrition
C) Frequent use of free health screenings
D) Being underinsured or having no insurance
RATIONALE: Financial barriers prevent people from accessing healthcare, leading to
the underinsured or uninsured status [D] that limits medical visits. High costs for
medicine [A] and lack of healthy food [B] further weaken the immune system and make
it harder to treat infections early.
11. By ensuring a patient is turned and fed properly to keep skin intact, the nurse
breaks the chain of infection by removing which link?
A) Portal of entry
