Nokea
An occupational health nurse is interpreting the results of a tuberculin skin test for a group of clients who received the test 48 hr ago. Which of the following clients should the nurse identify as having a positive test result?
- A. A client whose injection site is scabbed
- B. A client whose injection site is firm and measures 3 mm (0.1 in)
- C. A client whose injection site has an elevated area measuring 15 mm (0.6 in)
- D. A client whose injection site is ecchymotic
Correct Answer: C
Rationale: An induration of 15 mm after 48 hours indicates a positive TB skin test, suggesting exposure or infection. Smaller indurations, scabbing, or bruising do not meet the criteria for a positive result.

A nurse is collecting data from a client who is perimenopausal. Which of the following findings is the priority for the nurse to report to the provider?
- A. Difficulty sleeping
- B. Hot flashes
- C. Vaginal dryness
- D. Urinary frequency
Correct Answer: D
Rationale: Perimenopause brings hormonal shifts, but urinary frequency stands out it may signal a UTI, bladder issue, or pelvic pathology, requiring urgent evaluation over typical symptoms. Difficulty sleeping and hot flashes stem from estrogen fluctuations, common and manageable with lifestyle changes. Vaginal dryness, also hormonal, responds to lubricants or estrogen therapy, not immediate concern. Frequency, however, risks infection or renal complications older women often present atypically (e.g., confusion), per geriatric guidelines. Using ABCs, elimination issues outrank comfort, driving prompt reporting for diagnostics (e.g., urinalysis), preventing progression, making it the priority finding.
A nurse is preparing to perform tracheostomy care for a client. In which order should the nurse take the following steps?
- A. Ensure a method to communicate during the procedure.
- B. Wear clean gloves to remove the tracheostomy dressing.
- C. Clean the inner cannula using a small brush.

Client brought to the emergency department (ED) following a fall that occurred while downhill skiing. Client states they fell when turning to avoid hitting another skier. Client reports feeling a severe, sudden pain of right leg upon falling. Right leg was immobilized at the scene and client transported to the ED.
Client states they were wearing a helmet while skiing. Client reports no headache or loss of consciousness.
Client reports pain as 10 on a scale of 0 to 10 to the right lower leg Just below the knee and is unable to bear weight.
Right proximal tibia ecchymotic and swollen below the knee. Area is painful to touch. Open area noted on skin with bone visible. Right knee appears displaced. Left pedal pulses 3+, foot warm with intact movement and sensation. Right pedal pulses 1+, foot cool to palpation with minimal movement and reduced sensation.
Diagnostic Results
Day 1:
X-ray of right leg: open spiral tibial shaft fracture
Which of the following actions should the nurse take? (Post-fasciotomy)
- A. Prepare to administer an antibiotic
- B. Administer an analgesic
- C. Restrict fluid intake.
- D. Prepare to obtain a wound culture.
- E. Initiate supplemental oxygen.
- F. Elevate the leg.

Rationale: Antibiotics prevent infection, analgesics manage pain, and a wound culture assesses for infection post-fasciotomy.
A nurse is reinforcing teaching with a newly licensed nurse who is caring for a client who has AIDS. The nurse should instruct the newly licensed nurse to clean spills of the client's blood with a solution of water and which of the following cleaning agents?
- A. Isopropyl alcohol
- B. Hydrogen peroxide
- C. Bleach
- D. Chlorhexidine
Correct Answer: C
Rationale: AIDS, caused by HIV, requires strict infection control due to bloodborne transmission risk. Option C, bleach (typically a 1:10 dilution with water), is correct CDC guidelines recommend it for disinfecting HIV-contaminated surfaces, as it effectively inactivates the virus by denaturing proteins. Option A, isopropyl alcohol, disinfects but isn't the standard for blood spills; it evaporates quickly, potentially leaving viable pathogens. Option B, hydrogen peroxide, oxidizes but lacks evidence as a primary bloodborne pathogen disinfectant compared to bleach. Option D, chlorhexidine, excels for skin antisepsis, not environmental surfaces or blood cleanup. Bleach's broad-spectrum efficacy, affordability, and alignment with universal precautions make it the gold standard. Teaching this ensures the new nurse protects themselves and others, adhering to OSHA and hospital protocols, while reinforcing the importance of proper dilution (e.g., 1 part bleach to 9 parts water) for safety and effectiveness.
A nurse in a long-term care facility is providing care for a client who has Alzheimer's disease and is agitated. Which of the following interventions should the nurse implement?
- A. Administer a prescribed oral dose of trazodone to the client.
- B. Encourage the client to ambulate with a staff member.
- C. Isolate the client in their room.
- D. Apply bilateral wrist restraints to the client.
Correct Answer: A
Rationale: Prescribed trazodone addresses agitation pharmacologically. Other options are less effective or inappropriate for immediate management of agitation in Alzheimer's.
