The nurse is to begin a nitroglycerin infusion for a client diagnosed with an anterior wall myocardial infarction. Which assessment finding should the nurse report to the provider immediately?

Serum potassium of 5.2 mEq/L (normal 3.5 mEq/L-5.3 mEq/L.)

T wave depression on electrocardiogram

Heart rate of 90 beats per minute

Blood pressure of 90/50

Answer and Explanation

The Correct Answer is D

A. Serum potassium of 5.2 mEq/L: A potassium level of 5.2 mEq/L is slightly elevated but is still within a potentially acceptable range (normal is 3.5-5.3 mEq/L). While elevated potassium can be a concern, particularly in the context of an MI or with certain medications (like potassium-sparing diuretics), this level is not critically high. The nurse should monitor the potassium levels, but this is not an urgent finding requiring immediate reporting unless it increases further or is accompanied by significant symptoms (such as arrhythmias).

B. T wave depression on electrocardiogram (ECG): T wave depression can be a sign of ischemia or injury, which is common in the setting of an acute myocardial infarction. However, T wave changes are expected in this context and do not indicate an immediate emergency. The nurse should continue to monitor the ECG for any progression or worsening of ischemic changes but should prioritize concerns such as hypotension or worsening clinical status over this finding.

C. Heart rate of 90 beats per minute: A heart rate of 90 beats per minute is within normal limits (60-100 beats per minute), especially in the early stages of an MI. Nitroglycerin may cause a reflex tachycardia as a compensatory response to the decreased blood pressure, but a heart rate of 90 bpm is not an alarming finding. The nurse should continue to monitor the heart rate, but it is not the most pressing concern compared to hypotension. 4o mini

D. Blood pressure of 90/50: A blood pressure of 90/50 mmHg is significantly low and could indicate that the client is experiencing hypotension, which is a known side effect of nitroglycerin infusion. Nitroglycerin causes vasodilation, which can reduce blood pressure, especially in clients who are already at risk due to an acute myocardial infarction (MI). Low blood pressure can compromise perfusion to vital organs, including the heart, brain, and kidneys, and may lead to shock if not corrected promptly. This finding should be reported immediately to the healthcare provider, as it may require adjustment of the nitroglycerin dosage or discontinuation of the infusion.

Correct Answer is B

Explanation

A) Apply 4L of nasal oxygen, administer a cough suppressant, and place client on bedrest:
This approach is inappropriate for a client with bacterial pneumonia. While oxygen therapy may be necessary for some clients, administering a cough suppressant in this scenario is counterproductive. Pneumonia often leads to the accumulation of secretions, and suppressing the cough would prevent the client from clearing mucus from their airways, potentially worsening the condition. Bedrest is generally indicated, but it should not be the sole intervention.

B) Increase fluid intake, administer antibiotic(s), and facilitate adequate coughing:
This is the most appropriate plan of care. Increasing fluid intake helps to thin the mucus, making it easier to clear from the airways, which is crucial in pneumonia. Antibiotics are necessary to treat the bacterial infection causing pneumonia. Facilitating adequate coughing helps the client expel secretions, reducing the risk of airway obstruction and improving oxygenation. Coarse rhonchi indicate the presence of mucus or secretions, which should be cleared with effective coughing.

C) Decrease activity, increase bronchodilator use, and encourage pursed lip breathing:
Decreasing activity is generally appropriate for a client with pneumonia to reduce fatigue, but increasing bronchodilator use is not typically indicated unless there is underlying bronchospasm, such as in asthma or COPD. Pursed lip breathing can help improve ventilation, but it is more beneficial for clients with obstructive airway diseases, not primarily for those with bacterial pneumonia. Therefore, this option does not address the immediate needs of the client.

D) Place in prone position, begin steroid therapy, and monitor glucose levels:
While prone positioning is helpful in some conditions like acute respiratory distress syndrome (ARDS), it is not routinely used for bacterial pneumonia unless the client has severe hypoxemia and requires advanced respiratory support. Steroid therapy is generally not indicated for bacterial pneumonia unless there is a specific inflammatory component (such as a superimposed condition like asthma or COPD). Monitoring glucose levels may be important in clients on steroid therapy, but this is not a primary concern in the treatment of bacterial pneumonia.

A. pH 7.33, PaCO2 35 mmHg, Pa02 78 mmHg, HCO3 20 mEq/L. B. heart rate 80 and respiratory rate 20. C. 02 saturation of at least 94%. D. sodium 135 mg/di. and potassium 4.8 mg/dL.

Correct Answer is C

Explanation

A. pH 7.33, PaCO2 35 mmHg, PaO2 78 mmHg, HCO3 20 mEq/L:
This answer choice indicates respiratory acidosis (pH < 7.35, low bicarbonate), but the goal in acute respiratory failure is not just to adjust the pH alone; the more immediate concern is correcting oxygenation. The PaO2 of 78 mmHg is below the normal range (80-100 mmHg), indicating hypoxemia that should be corrected first. The goal should be to improve PaO2 to acceptable levels (≥80 mmHg) and achieve adequate oxygen saturation. This ABG result does not fully align with the immediate goals of treatment.

B. Heart rate 80 and respiratory rate 20:
While normal vital signs like heart rate and respiratory rate are important, they are not the primary goal of treatment in acute respiratory failure. The focus during ventilator support is to improve oxygenation and ventilation rather than simply achieving normal heart and respiratory rates. In acute respiratory failure, abnormal heart and respiratory rates are often a result of hypoxia or hypercapnia (high CO2), so normalizing oxygenation and carbon dioxide levels is more critical initially.

C. O2 saturation of at least 94%:
The primary goal in acute respiratory failure is to maintain adequate oxygenation. In this context, the goal of ventilator support is to correct hypoxemia (low blood oxygen levels) and restore normal oxygen saturation. A target oxygen saturation of at least 94% is commonly considered appropriate for most patients in acute respiratory failure to ensure that tissues are receiving enough oxygen to prevent organ damage. This is a key aspect of managing respiratory failure and ensuring adequate tissue perfusion. Oxygen saturation below 90% is typically considered to indicate a severe level of hypoxemia, requiring prompt intervention.

D. Sodium 135 mg/dL and potassium 4.8 mg/dL:
While electrolyte levels are important to monitor in any critically ill patient, the main goal of treatment in acute respiratory failure is improving oxygenation and ventilation rather than focusing specifically on normalizing sodium or potassium levels. Correcting imbalances in electrolytes can be part of overall care, but it is not the primary objective in this situation. Oxygenation (as measured by PaO2 and O2 saturation) takes priority over correcting individual electrolytes.
