A nurse is caring for a client who has pneumonia caused by Heemophilus influenzae type B. Which of the following types of isolation precautions should the nurse implement?

Rationale for Correct Choices

• Meningitis: The client’s high fever, chills, photophobia, nausea, and severe headache lasting several days strongly indicate meningitis. The presence of nuchal rigidity is a hallmark meningeal sign, supporting this diagnosis. The client’s tachycardia, lethargy, and borderline hypotension further signal a systemic inflammatory response consistent with infectious meningitis.

• Decrease environmental stimuli: Clients with meningitis are extremely sensitive to light and noise due to meningeal irritation, which can worsen headache and neurologic distress. Reducing stimuli helps reduce intracranial irritation, improves comfort, and can prevent worsening neurologic symptoms during the acute phase.

• Initiate neurological checks every 2 hr: Close monitoring detects early changes in level of consciousness, pupillary responses, and cranial nerve function caused by meningeal inflammation or rising intracranial pressure. Frequent neuro checks are vital for recognizing deterioration that requires immediate intervention.

• Temperature: Fever is a major indicator of infection severity in meningitis, and sustained hyperthermia increases metabolic demand and risk of neurologic injury. Monitoring temperature helps guide treatment effectiveness and determine the need for antipyretics or cooling measures.

• Vascular changes: Systemic infection can lead to changes such as tachycardia, hypotension, and prolonged capillary refill, signaling progression toward septic shock. Monitoring vascular status helps detect hemodynamic instability early in clients with meningitis.

Rationale for Incorrect Choices

• Hydrocephalus: Hydrocephalus typically presents with progressive neurological decline, altered mental status, and signs of increased intracranial pressure, not acute fever, nuchal rigidity, or photophobia. The client’s symptoms point toward infection rather than cerebrospinal fluid accumulation.

• Migraine headache: Migraines cause photophobia and nausea but do not usually produce high fever, chills, nuchal rigidity, or systemic symptoms. The presence of infection markers and meningeal signs makes migraine unlikely.

• Septic shock: Although the client is febrile and tachycardic, septic shock involves more pronounced hypotension and signs of end-organ dysfunction. The client’s symptoms indicate meningitis as the underlying cause rather than primary shock.

• Prepare the client for surgery: Surgery is not indicated in meningitis unless complications such as abscesses or obstructive hydrocephalus occur. The priority is medical management, neurological monitoring, and infection control.

• Administer gabapentin: Gabapentin is used for neuropathic pain and seizure disorders, and does not treat the infectious or inflammatory processes involved in meningitis. It does not address acute symptoms or underlying pathology.

• Administer sumatriptan: Sumatriptan is indicated for migraines and is contraindicated in conditions involving infection, fever, or neurologic compromise. Its vasoconstrictive effects could worsen cerebral perfusion in meningitis.

• Gait: Gait changes can occur in chronic neurologic disorders but are not a priority assessment in the acute management of meningitis. Immediate monitoring focuses on neurologic status and hemodynamic stability.

• Bowel sounds: Although documented as hyperactive on admission, bowel sounds do not reflect the severity or progression of meningitis. They do not guide treatment decisions for infectious or neurologic complications.

• Lactate level: Lactate monitoring is primarily associated with septic shock and poor tissue perfusion. While meningitis can progress to sepsis, the client’s current presentation prioritizes neurologic and temperature monitoring over lactate assessment.

A. Blood glucose level: The client’s blood glucose is 103 mg/dL, which is within normal limits. While monitoring glucose is important for a client with diabetes, this finding does not require immediate follow-up in acute chest pain and suspected myocardial infarction.

B. Bowel sounds: Bowel sounds are present in all four quadrants, indicating normal gastrointestinal function. This assessment is routine and does not necessitate urgent follow-up compared with cardiovascular concerns.

C. Blood pressure: The client’s blood pressure is 164/80 mm Hg, indicating hypertension. Elevated blood pressure can increase myocardial oxygen demand and worsen cardiac ischemia, making it important to address immediately.

D. Pain level: The client reports chest tightness rated 7/10 with radiation to the left arm and associated nausea and diaphoresis. This presentation is characteristic of acute myocardial infarction and requires immediate intervention to reduce myocardial damage and prevent complications.

E. Electrocardiogram findings: The ECG shows tachycardia with ST-segment elevation and T-wave changes, indicating myocardial injury or infarction. Immediate follow-up is critical to initiate reperfusion therapy and prevent further cardiac damage.

F. Lung sounds: Lungs are clear to auscultation, which is expected and does not indicate acute respiratory compromise. No immediate follow-up is required in this context.

G. Troponin T level: Troponin T is elevated at 0.40 ng/mL, confirming myocardial injury. This requires urgent follow-up to guide treatment and assess the extent of cardiac damage.
