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

Findings that indicate the client has a potential problem:

• Chest pain radiating to left arm: Chest pain that radiates to the left arm is a classic symptom of a myocardial infarction (MI). The description of pain (tightness) and its radiation to the left arm are a red flag for an acute cardiac event, which requires immediate intervention.
• Pain level of 7 on a scale of 0 to 10: A pain level of 7 indicates significant discomfort, and when combined with other symptoms like chest tightness and radiation to the left arm, it further supports the possibility of a myocardial infarction.
• Started to feel nauseous after breakfast: Nausea can be an associated symptom of acute myocardial infarction (MI), especially in women, the elderly, and those with diabetes. Its presence, along with chest pain, is concerning.
• Diaphoresis: Diaphoresis (excessive sweating) is often associated with myocardial infarction and is a key sign of acute coronary syndrome. This finding, along with chest pain and shortness of breath, suggests an emergent situation.
• Tachycardia with irregular heart rate: The client’s heart rate is 110/min and irregular, which can be indicative of arrhythmias commonly seen in acute myocardial infarction. The irregular and tachycardic rhythm should be immediately evaluated to prevent further complications.
• +1 pedal pulses: While present, +1 pedal pulses are diminished. This could indicate compromised peripheral circulation, possibly related to overall cardiovascular compromise or underlying peripheral artery disease, which is often co-morbid with the client's existing conditions (hyperlipidemia, hypertension, diabetes).
• Skin is cool to touch: Cool skin, especially when accompanied by other signs of poor perfusion like diminished pulses, can indicate reduced peripheral blood flow, which may be a systemic response to decreased cardiac output from a significant cardiac event.

Rationale for Incorrect Findings:

• Lungs clear to auscultation: Clear lung sounds suggest no signs of pulmonary edema or other lung issues at the moment, ruling out respiratory causes of the symptoms.
• Bowel sounds present in all 4 quadrants: The presence of bowel sounds in all quadrants is normal and suggests that the gastrointestinal system is functioning well.
• Capillary refill less than 2 seconds is normal and indicate adequate perfusion, this finding on its own does not require follow up.

Rationale for Correct Choices:

• Hypovolemic shock: The client’s symptoms at 0100 of dizziness, low urine output (30 mL in the last hour) are indicative of hypovolemic shock likely due to aggressive diuresis from the 80 mg IV furosemide administered. Fluid volume depletion leads to reduced circulating blood volume, resulting in these symptoms, which are consistent with hypovolemic shock.
• Elevate the client's feet: Elevating the client’s feet is a key intervention to improve venous return, which can increase blood flow to the heart and improve circulation. This is particularly useful in hypovolemic shock to promote better blood flow and tissue perfusion.
• Administer IV fluids: IV fluids are critical for restoring the lost fluid volume in hypovolemic shock. Given the low urine output and signs of dehydration, fluid resuscitation will help stabilize the client’s hemodynamic status by increasing circulating volume.
• Mental status: Mental status is a key parameter to monitor in shock states. Decreased cerebral perfusion due to hypovolemia can lead to confusion, agitation, or lethargy. Regular monitoring will help assess if the shock is worsening and if more aggressive interventions are needed.
• Pulse pressure: Pulse pressure (the difference between systolic and diastolic blood pressure) is often narrowed in hypovolemic shock due to reduced stroke volume. Monitoring pulse pressure helps assess the severity of shock and the effectiveness of interventions such as fluid resuscitation.

Rationale for Incorrect Choices:

• Cardiogenic shock: Cardiogenic shock occurs when the heart is unable to pump effectively, leading to inadequate tissue perfusion. While the client does have a history of heart failure, the current presentation, including fluid retention, dizziness, and low urine output, is more indicative of hypovolemic shock.
• Obstructive shock: Obstructive shock occurs due to a physical obstruction in blood flow (e.g., pulmonary embolism, cardiac tamponade, or tension pneumothorax). The client’s symptoms do not suggest any form of obstruction; they are consistent with fluid volume depletion.
• Septic shock: Septic shock is caused by widespread infection leading to systemic inflammation and vasodilation. The client does not show signs of infection (such as fever or abnormal WBC count) or sepsis, making septic shock unlikely.
• Administer 1 unit of packed RBC: This client’s condition is related to fluid loss, not blood loss, so administering blood products is not appropriate. The priority in hypovolemic shock is to restore fluid volume, not blood volume.
• Administer IV antibiotics: IV antibiotics are used for treating infections, particularly in cases of septic shock. The client does not exhibit signs of infection (such as fever or elevated WBC), so the use of antibiotics is not warranted here.
• Obtain a lactate level: Lactate levels are useful in diagnosing septic shock and assessing tissue hypoxia. While lactate levels can be elevated in shock conditions, the primary cause here appears to be fluid loss, so lactate measurement is not the priority.
• Blood culture results: Blood cultures are used to diagnose infections or sepsis. Since the client is not showing signs of infection (such as fever or elevated WBC), blood cultures are not necessary.
• Platelet count: Platelet count is relevant in conditions that involve bleeding or clotting disorders. The client does not exhibit signs of a clotting issue or bleeding; therefore, monitoring platelets is not required.
• Temperature: Temperature monitoring is important in septic shock to identify infection. However, the client’s temperature is within a normal range 36.2, and there are no indications of infection or systemic inflammation.
