The nurse is caring for a client with Hepatitis A. The client asks how someone gets this disease. What is the most likely cause of the client’s Hepatitis A?
Being exposed to blood or blood products
Having unprotected sex
Sharing needles for illicit drugs
Eating contaminated food or water
The Correct Answer is D
Hepatitis A is an acute, self-limiting viral infection of the liver caused by the HAV virus. It is primarily transmitted through the fecal-oral route, often involving the ingestion of substances contaminated by an infected person. Proper hand hygiene and sanitation are the most effective ways to prevent the spread of this highly contagious enteric pathogen.
Rationale:
A. Exposure to blood or blood products is the primary transmission route for Hepatitis B and C, but not Hepatitis A. The HAV virus is not typically found in high concentrations in the blood for long periods. Therefore, percutaneous exposure is an extremely rare and unlikely cause of this specific type of viral hepatitis infection.
B. Having unprotected sex is a risk factor for sexually transmitted infections and blood-borne viruses like Hepatitis B and HIV. While some forms of sexual contact involving fecal exposure can transmit Hepatitis A, it is not categorized primarily as a sexually transmitted disease. The most common source in general populations remains contaminated food or water supplies.
C. Sharing needles is a high-risk behavior for transmitting parenteral viruses such as Hepatitis C and B. Hepatitis A is not commonly associated with intravenous drug use unless there is concurrent poor sanitation or fecal contamination. The transmission mechanism of HAV is almost exclusively through the digestive tract rather than through direct bloodstream injection.
D. Eating contaminated food or water is the most likely cause of Hepatitis A. This occurs when food is handled by an infected individual with poor hand hygiene or when water supplies are tainted with sewage. Outbreaks are frequently traced back to raw shellfish or contaminated produce, making enteric precautions the standard for preventing the spread of HAV.

Correct Answer is D
Explanation
Patients with cirrhosisresulting from substance use disorders often face significant psychosocial stressors and strained interpersonal relationships. Effective nursing care requires a therapeutic communicationapproach that addresses the patient's emotional needs without being judgmental or dismissive. Identifying a robust support systemis a clinical necessity for long-term recovery and adherence to the complex medical regimen required for chronic liver management.
Rationale:
A.Telling the patient they should make peace with their family is a directive and non-therapeutic response. It places a burden of responsibility on the patient that may be unrealistic given the complexity of their family dynamics. This response ignores the patient's current feelings and fails to provide professional support for their social isolation.
B.Stating that the patient "must" attend Alcoholics Anonymous is a demanding and authoritative response. While support groups are beneficial, this approach may cause the patient to become defensive and withdraw from communication. It does not address the patient's immediate emotional distress regarding their family or offer a personalized plan for their social recovery.
C.Comparing the patient's situation to the nurse's own family is unprofessional and dismissive. This response shifts the focus away from the client and onto the nurse, which is a violation of therapeutic boundaries. It trivializes the patient's pain and fails to provide the empathetic, client-centered care required in a clinical setting.
D.Responding with "I will help you identify a support system" is therapeutic and proactive. This response acknowledges the patient's perceived lack of social support and offers a professional solution. By focusing on building a support network, the nurse helps the patient find resources that are essential for maintaining sobriety and managing the psychological impact of their disease.
Correct Answer is D
Explanation
In nursing prioritization, the ABC framework(Airway, Breathing, Circulation) is used to identify the most unstable patient. Chronic kidney failure patients are at high risk for fluid volume excessbecause their kidneys cannot excrete metabolic water or sodium. This can rapidly lead to pulmonary edema, where fluid leaks into the alveoli, causing life-threatening gas exchange impairment that requires immediate oxygenation, diuresis, or emergent dialysis.
Rationale:
A.Assisting with a peritoneal dialysis bag change is a routine task that does not represent an acute physiological emergency. While dialysis is important for long-term stability, it is a scheduled procedure for a stable patient. This task can be delayed or delegated to an appropriately trained staff member while the nurse addresses more urgent respiratory distress.
B.A client scheduled for an arteriovenous fistula insertion is likely stable and undergoing a planned surgical procedure. This patient requires preoperative teaching and preparation, but there is no indication of active hemodynamic or respiratory compromise. They do not take precedence over a patient experiencing acute symptoms of fluid overload and impaired breathing.
C.Azotemia and rising BUN/creatinine levels are expected findings in patients with renal insufficiency. While these trends require monitoring and eventual intervention, they do not indicate an immediate threat to the patient's life within the next few minutes. Lab values alone are secondary to the assessment of active, symptomatic clinical deterioration like respiratory distress.
D.The nurse must assess the client with shortness of breathfirst because it indicates potential pulmonary edemaor metabolic acidosis. In the context of chronic kidney failure, new-onset dyspnea is a red flag for acute respiratory failure due to fluid overload. This patient requires immediate assessment of lung sounds and oxygen saturation to prevent respiratory arrest.
