ADVANCED PATHOPHYSIOLOGY
,Advanced Practice Nurse: Knee Pain With Normal Imaging
An advanced practice registered nurse (APRN) is evaluating an adult patient who reports
knee pain that worsens with stair climbing and running. The pain improves with rest,
heat application, and ibuprofen. On physical examination, the nurse notes localized
tenderness, swelling, and inflammation around the knee joint. However, there is no
visible deformity, and radiologic imaging shows no abnormalities. The APRN is asked to
determine the most likely diagnosis based on these findings.
Which diagnosis should the APRN make for this patient?
A. Bursitis
B. Paget disease
C. Osteoporosis
D. Fibrosarcoma
Correct Answer: A. Bursitis
Rationale
Bursitis is an inflammatory condition affecting the bursae, which are fluid-filled sacs that
reduce friction between bones and soft tissues. It commonly results from repetitive
movement, overuse, or prolonged pressure on a joint, particularly the knee. The pain
typically worsens with activity and improves with rest, heat, and anti-inflammatory
medications such as NSAIDs. Clinical findings often include localized swelling,
tenderness, and warmth without structural deformity or radiographic changes. Unlike
bone disorders or malignancies, bursitis is primarily a soft-tissue inflammatory condition
rather than a destructive bone disease.
,Teratogenic Medication Risk in Pregnancy
An advanced practice registered nurse (APRN) is assessing a teenage patient who has
recently discovered she is pregnant. During medication reconciliation, the APRN
identifies a drug that is known to cause serious fetal abnormalities if taken during
pregnancy. The nurse must determine which medication poses a teratogenic risk and
should be avoided.
Which medication is the APRN most concerned about?
A. Retinoic acid
B. Clindamycin
C. Benzoyl peroxide
D. Bisphenol A
Correct Answer: A. Retinoic acid
Rationale
Retinoic acid (a vitamin A derivative) is highly teratogenic and is strongly associated with
congenital malformations when taken during pregnancy. It can disrupt normal
embryonic development, particularly affecting the central nervous system, heart, and
craniofacial structures. For this reason, it is contraindicated in pregnancy and requires
strict contraceptive use during treatment. Other listed medications, such as clindamycin
and benzoyl peroxide, do not carry the same level of teratogenic risk. Early identification
of teratogens is essential to prevent fetal harm.
, Chronic Venous Insufficiency With Infected Leg Wound
An advanced practice registered nurse (APRN) is caring for a patient diagnosed with
chronic venous insufficiency who presents with a lower extremity wound that is red,
warm, swollen, painful, and producing drainage. The APRN recognizes that the wound
appears infected and requires appropriate medical management.
Which treatment should the APRN initiate for this patient?
A. Antivirals
B. Anticoagulants
C. Antibiotics
D. Antihistamines
Correct Answer: C. Antibiotics
Rationale
The clinical presentation of redness, warmth, swelling, pain, and drainage is consistent
with cellulitis, a bacterial infection of the dermis and subcutaneous tissue. Patients with
chronic venous insufficiency are at increased risk due to poor circulation and skin
breakdown. Systemic antibiotics are the primary treatment to eliminate the bacterial
infection. Antivirals are ineffective against bacterial infections, and anticoagulants or
antihistamines do not address the underlying infectious process. Prompt treatment
prevents progression to more severe systemic infection.
