## 문제

A nurse is assessing a patient with HIV/AIDS who has been experiencing persistent fever, night sweats, and weight loss. Which assessment finding would be most concerning and require immediate intervention?

## 보기

1. CD4+ T cell count of 350 cells/mm³
2. Oral thrush with white patches on the tongue
3. Temperature of 102.8°F (39.3°C) with altered mental status **✔ 정답**
4. Unexplained weight loss of 15 pounds over 3 months

**정답: 3**

## 해설

Temperature of 102.8°F with altered mental status indicates a potential life-threatening opportunistic infection or sepsis requiring immediate medical intervention. Other findings are concerning but not immediately life-threatening.

Clinical Reasoning and Priority Setting

In a patient with HIV/AIDS presenting with constitutional symptoms such as persistent fever, night sweats, and weight loss, the nurse must rapidly differentiate between expected disease-related complications and acute, life-threatening emergencies. The finding that requires immediate intervention is a temperature of 102.8°F (39.3°C) accompanied by altered mental status.

Pathophysiology and Clinical Correlation

The combination of high fever and altered mental status in an immunosuppressed patient is a classic and critical red flag for acute meningitis or meningoencephalitis. In the context of HIV/AIDS, the immune system's ability to contain pathogens is severely compromised. This allows for a broader range of causative organisms, including opportunistic infections, to invade the central nervous system (CNS). The research by Román-Montes et al. specifically highlights that immunosuppressed patients are at a distinct disadvantage, facing risks due to atypical clinical presentations and a wider array of potential pathogens [1]. A typical presentation of meningitis, such as a stiff neck, may be absent or blunted, making the non-specific finding of altered mental status even more significant as a primary indicator of CNS involvement. This change in consciousness reflects direct brain tissue irritation, increased intracranial pressure, or systemic sepsis, all of which demand emergent evaluation and intervention to prevent irreversible neurological damage or death.

Analysis of Other Options

The other findings are significant and require nursing action, but they do not represent the same level of immediate threat to the patient's airway, breathing, or circulation as a potential CNS infection.

- Option 1: A CD4+ T cell count of 350 cells/mm³ indicates a moderate level of immunosuppression. While this is below the normal range and guides long-term prophylactic and therapeutic strategies, it is a chronic laboratory value that does not, by itself, necessitate an emergency intervention during a single assessment shift.

- Option 2: Oral thrush (oropharyngeal candidiasis) is a common opportunistic infection in HIV/AIDS. White patches on the tongue are a clinical indicator of this local infection. It requires treatment with antifungal agents and monitoring, but it is not an immediately life-threatening condition unless it extends into the esophagus or airway, which is not indicated in this option.

- Option 4: Unexplained weight loss of 15 pounds over 3 months is a classic constitutional symptom of HIV/AIDS progression, often termed "wasting syndrome." This finding is concerning for overall disease trajectory and nutritional status and requires a comprehensive nutritional and medical management plan. However, it represents a chronic process, not an acute neurological emergency.

The nurse's priority is to recognize that a sudden change in mental status paired with a high fever in an immunocompromised host is a medical emergency, most concerning for a CNS infection, which aligns with the documented risks of atypical presentations and diverse pathogens in this population [1].References (research sources)

Fever & Altered Mental Status in HIV/AIDSRapid Recognition of CNS Infection
In an immunocompromised patient, the combination of a temperature of 102.8°F (39.3°C) and altered mental status is a critical red flag for meningitis or meningoencephalitis. Classic signs like nuchal rigidity may be absent, making a change in consciousness the primary indicator of CNS involvement.

Immediate nursing actions include notifying the provider, preparing for a lumbar puncture and blood cultures, and initiating seizure and airway precautions. Do not delay care while waiting for a CD4 count, as this is not an acute emergency indicator.

CautionDo not attribute altered mental status solely to fever or systemic illness. In an immunosuppressed patient, it must be assumed to be a life-threatening CNS infection until proven otherwise, requiring emergent evaluation and broad-spectrum antimicrobial coverage.

## 핵심 개념

- **Altered Mental Status** — A change in consciousness or cognition, often the primary sign of CNS infection in immunosuppressed patients where classic signs like nuchal rigidity may be absent.
- **Meningoencephalitis** — Inflammation of the brain and meninges, a life-threatening condition often caused by opportunistic infections in patients with HIV/AIDS.
- **Constitutional Symptoms** — Systemic symptoms such as persistent fever, night sweats, and unexplained weight loss, commonly associated with chronic infections or malignancies.
- **Opportunistic Infection** — An infection caused by pathogens that take advantage of a weakened immune system, such as in HIV/AIDS when CD4 counts are low.
- **CD4+ T cell count** — A laboratory measure of immune function; a count of 350 cells/mm³ indicates moderate immunosuppression but is not an acute emergency.
