A nurse is caring for a client who has the following arterial blood gas results: HCO3 18 mEq/L, PaCO2 28 mm Hg, and pH 7.30. The nurse recognizes the client is experiencing which of the following acid-base imbalances?

Metabolic alkalosis

Respiratory alkalosis

Respiratory acidosis

Metabolic acidosis

Answer and Explanation

The Correct Answer is D

Choice A Reason:

Metabolic alkalosis is characterized by an elevated pH (greater than 7.45) and an increased bicarbonate (HCO3) level. In this case, the pH is 7.30, indicating acidosis, and the HCO3 level is 18 mEq/L, which is below the normal range (22-26 mEq/L). Therefore, metabolic alkalosis is not the correct diagnosis.

Choice B Reason:

Respiratory alkalosis is indicated by a high pH (greater than 7.45) and a low PaCO2 (less than 35 mm Hg). Although the PaCO2 is low at 28 mm Hg, the pH is 7.30, indicating acidosis rather than alkalosis. Therefore, respiratory alkalosis is not the correct diagnosis.

Choice C Reason:

Respiratory acidosis is characterized by a low pH (less than 7.35) and an elevated PaCO2 (greater than 45 mm Hg). In this case, the pH is low, indicating acidosis, but the PaCO2 is also low at 28 mm Hg, which does not fit the criteria for respiratory acidosis. Therefore, respiratory acidosis is not the correct diagnosis.

Choice D Reason:

Metabolic acidosis is indicated by a low pH (less than 7.35) and a low bicarbonate (HCO3) level (less than 22 mEq/L). In this case, the pH is 7.30, indicating acidosis, and the HCO3 level is 18 mEq/L, which is below the normal range. The low PaCO2 of 28 mm Hg suggests a compensatory respiratory response to the metabolic acidosis. Therefore, metabolic acidosis is the correct diagnosis.

Correct Answer is A

Explanation

Choice A reason:

Hypotension (low blood pressure), tachycardia (rapid heart rate), and lethargy are critical symptoms that can indicate a life-threatening condition such as shock or severe dehydration. Hypotension can lead to inadequate perfusion of vital organs, resulting in multi-organ failure if not promptly addressed1. Tachycardia is often a compensatory mechanism for hypotension, and lethargy indicates decreased cerebral perfusion. Immediate intervention is required to stabilize the patient’s condition and prevent further deterioration.

Choice B reason:

Dizziness with a headache rated 7/10 on the numeric scale is concerning but not immediately life-threatening. These symptoms could indicate a variety of conditions, such as migraine, vertigo, or even a mild concussion. While the patient should be assessed and treated, they do not present the same immediate risk as hypotension and tachycardia.

Choice C reason:

Abdominal pain, hypertension (high blood pressure), and constipation are symptoms that need medical attention but are not immediately life-threatening. Hypertension can lead to serious complications if left untreated, but it does not require the same urgent intervention as hypotension. Abdominal pain and constipation, while uncomfortable and potentially indicative of underlying issues, do not pose an immediate threat to life.

Choice D reason:

Febrile (fever), tachycardia, and vomiting are symptoms that suggest an infection or other acute illness. While these symptoms are concerning and need prompt evaluation, they do not pose the same immediate risk as hypotension and tachycardia. Fever and vomiting can lead to dehydration, but this typically develops over a longer period compared to the rapid deterioration seen with hypotension.

A. QT interval B. Heart rate C. Respiratory rate D. Heart rhythm E. Urine output

Correct Answer is ["A","B","D"]

Explanation

Choice A Reason:

Monitoring the QT interval is crucial when administering amiodarone because this drug can prolong the QT interval, increasing the risk of torsades de pointes, a potentially life-threatening form of ventricular tachycardia. The QT interval represents the time it takes for the heart’s ventricles to depolarize and repolarize, and prolongation can lead to arrhythmias. Regular monitoring helps in early detection and prevention of such adverse effects.

Choice B Reason:

Heart rate monitoring is essential when administering amiodarone because the drug can cause bradycardia (a slower than normal heart rate). Amiodarone affects the electrical conduction system of the heart, which can lead to significant changes in heart rate. Monitoring the heart rate ensures that any bradycardia is detected early and managed appropriately to prevent complications such as hypotension or heart failure.

Choice C Reason:

While respiratory rate monitoring is important in general patient care, it is not specifically necessary for monitoring the effects of amiodarone. Amiodarone primarily affects the heart’s electrical activity and has less direct impact on respiratory function. However, in cases of severe adverse reactions, such as pulmonary toxicity, respiratory monitoring may become relevant.

Choice D Reason:

Monitoring heart rhythm is vital when administering amiodarone because the drug is used to treat arrhythmias and can also cause new arrhythmias or exacerbate existing ones. Continuous ECG monitoring helps in detecting any abnormal heart rhythms early, allowing for timely intervention. This is particularly important in patients with a history of arrhythmias or those receiving high doses of amiodarone.

Choice E Reason:

Urine output monitoring is not specifically necessary for patients receiving amiodarone. While maintaining adequate urine output is important for overall patient health, amiodarone does not typically affect renal function directly. Therefore, urine output monitoring is not a primary concern when administering this medication.
