Which of the following nursing interventions would be appropriate for a client with sickle cell disease?
- A. Prepare the client for surgery
- B. Encourage fluid intake
- C. Provide a warm environment
- D. Keep the client strictly NPO
Correct Answer: B
Rationale: Sickle cell's sticky cells crave hydration fluids thin blood, easing vaso-occlusion, a top intervention to cut crisis. Surgery's rare, warmth helps pain, NPO starves. Nurses push intake, preventing sickling, a hydration win in this hemoglobin war.
Cardiac catheterisation (angiography) is performed to assess blood flow through the coronary arteries through use of a contrast agent and radiographic imaging. The nursing responsibilities in caring for the patient post angiography do not include:
- A. Applying pressure and observing the insertion site for bleeding or haematoma formation
- B. Informing the patient of the findings of the angiogram to allay fear and provide reassurance
- C. Monitor for arrhythmias by both cardiac monitoring and assessing apical or peripheral pulses
- D. Encourage fluids to increase urinary output and flush out the dye
Correct Answer: B
Rationale: Post-angio, nurses press sites, watch rhythms, flush dye hands-on musts. Telling results? Docs' turf nurses soothe, don't spill, a chronic care line.
Appropriate statements concerning radiology and trauma interventional radiology include:
- A. To rule out injury of the cervical spine in the unconscious patient, application of a protocol involving a computed tomography (CT) scan to the neck is recommended.
- B. A FAST (Focused Assessment with Sonography for Trauma) scan is a specific investigation for assessment of intraperitoneal bleeding.
- C. In a patient who is persistently hypotensive in the emergency department despite adequate fluid resuscitation, radiological interventions to treat bleeding caused by a pelvic fracture are not recommended.
- D. Interventional radiology has a role in the management of injuries to the liver, kidney and spleen.
Correct Answer: A
Rationale: Trauma radiology optimizes diagnosis and intervention. CT is the gold standard for cervical spine assessment in unconscious patients, per NICE guidelines, offering high sensitivity for fractures/ligamentous injury versus plain films. FAST scans detect free fluid (e.g., blood) intraperitoneally but lack specificity positive findings need confirmation (e.g., CT). Persistent hypotension with pelvic fracture warrants interventional radiology (e.g., embolization), not dismissal contrary to the statement. Interventional radiology manages solid organ injuries (liver, kidney, spleen) via embolization, reducing surgical need. Staffing in radiology matches theatre for critical cases. CT's diagnostic precision in cervical spine trauma ensures timely, accurate management, critical in unconscious patients where clinical exam is unreliable.
A chemotherapy drug that causes alopecia is prescribed for a patient. Which action should the nurse take to support the patient's self-esteem?
- A. Encourage the patient to purchase a wig or hat to wear when hair loss begins.
- B. Suggest that the patient limit social contacts until regrowth of the hair occurs.
- C. Teach the patient to wash hair gently with mild shampoo to minimize hair loss.
- D. Inform the patient that hair usually grows back once chemotherapy is complete.
Correct Answer: A
Rationale: Alopecia from chemo (e.g., cyclophosphamide) guts self-esteem prepping with wigs or hats hands control back, softening the blow. Limiting contact isolates; gentle washing won't stop it follicles are toast. Regrowth is true but delayed. Nurses in oncology push this proactive step it's practical, empowering, and tackles the psychosocial hit head-on.
For a patient who is receiving chemotherapy, which laboratory result is of particular importance?
- A. WBC
- B. PT and PTT
- C. Electrolytes
- D. BUN
Correct Answer: A
Rationale: Chemotherapy suppresses bone marrow, slashing white blood cell counts especially neutrophils heightening infection risk, making WBC monitoring paramount. Low counts trigger protective measures or treatment holds, directly tied to therapy's myelosuppressive core. PT and PTT track clotting, relevant for bleeding but less immediate. Electrolytes matter for overall status, but imbalances aren't chemotherapy's primary threat. BUN reflects kidney function, indirectly affected by some drugs, not the frontline concern. WBC's critical drop demands swift action fevers in neutropenia are emergencies underscoring its priority in safeguarding patients through treatment's immune-compromising phases.
