A client is admitted to the hospital for shortness of breath and chest pain after an episode of syncope. Which laboratory finding is most important for the nurse to report to the healthcare provider (HCP)?
Troponin I.
Blood glucose.
Oxygen saturation.
Hematocrit.
The Correct Answer is A
A. Troponin I: Troponin I is a highly specific marker for myocardial injury. Elevated levels suggest acute coronary syndrome or myocardial infarction, which could explain the client’s chest pain, shortness of breath, and syncope. This findings may indicate potential for life-threatening cardiac damage.
B. Blood glucose: Abnormal glucose levels can contribute to long-term cardiovascular risk and may affect recovery, but they are not the priority in the acute setting unless critically low or high. They do not explain the acute onset of chest symptoms and syncope.
C. Oxygen saturation: While oxygen saturation is important, it is typically monitored continuously or via spot checks. Unless critically low, a slight reduction in oxygen saturation would not be as urgent as a positive cardiac biomarker in this clinical context.
D. Hematocrit: A low hematocrit could indicate anemia, which might contribute to fatigue or dyspnea, but it is not as immediately concerning as cardiac ischemia in a client with chest pain and syncope. It is a secondary concern in this case.

Correct Answer is D
Explanation
A. Unilateral calf pain: This is a classic sign of DVT, indicating localized clot formation in the leg. While significant, it is not as immediately life-threatening as signs of pulmonary embolism and does not require urgent reporting if PE is already suspected.
B. Intravenous site inflammation: IV site inflammation may suggest phlebitis or local irritation but is not related to the acute life-threatening nature of pulmonary embolism. It should be addressed but does not warrant immediate escalation over respiratory symptoms.
C. Pedal edema: Pedal edema is a common finding in DVT or chronic venous insufficiency and may be present without acute complications. Although it supports the history of venous thromboembolism, it is not urgent unless associated with other signs of decompensation.
D. Difficulty breathing: Sudden onset dyspnea is a hallmark symptom of pulmonary embolism and may signal impaired gas exchange or hemodynamic compromise. This finding must be reported immediately as it indicates potential life-threatening embolic obstruction in the pulmonary circulation.
Correct Answer is B
Explanation
A. Respiratory rate of 22 breaths/minute: This rate is mildly elevated and may reflect exertional dyspnea or anxiety, but it does not indicate immediate respiratory distress. It requires monitoring but does not demand urgent intervention.
B. Production of frothy, pink-tinged secretions: This finding is a hallmark of acute pulmonary edema and signals severe left-sided heart failure with fluid backing up into the alveoli. It compromises oxygenation and requires urgent intervention, such as diuretics and supplemental oxygen.
C. Pitting edema of the ankles bilaterally: Pitting edema reflects chronic volume overload, often associated with right-sided heart failure. While concerning, it develops over time and is not as immediately life-threatening as pulmonary congestion with compromised gas exchange.
D. Irregular apical heart rhythm: An irregular rhythm is consistent with atrial fibrillation and explains the palpitations, but it is a known condition in this case. Unless accompanied by hemodynamic instability, it does not demand immediate intervention on its own.
