A nurse is reviewing the arterial blood gas values of a client who has chronic kidney disease. Which of the following sets of values should the nurse expect?
pH 7.25, HCO3- 19mEq / L PaCO2 30 mm Hg
pH 7.30, HCO3-26 26mEq / L PaCO2 50 mm Hg
pH 7.50 0. HCO * 3 - 20mE /L, PaCO2 32 mm Hg
pH 7.55, HCO3- 30mEq / L PaCO2 31 mm Hg
The Correct Answer is A
In a client with chronic kidney disease (CKD), metabolic acidosis is a common acid-base disorder due to impaired excretion of acid and decreased bicarbonate reabsorption in the kidneys. The arterial blood gas values associated with metabolic acidosis in CKD are a low pH (acidemia), low bicarbonate (HCO3-), and normal or low partial pressure of carbon dioxide (PaCO2). Option A fits this pattern, with a pH of 7.25 (acidic), HCO3- of 19 mEq/L (low), and a PaCO2 of 30 mm Hg (within the normal to low range).
Option B shows a pH of 7.30 (acidic) but with a higher bicarbonate level of 26 mEq/L, which is not consistent with metabolic acidosis. The elevated bicarbonate level suggests metabolic alkalosis, which is not expected in a client with CKD.
Option C has a pH of 7.50 (alkaline) with an elevated bicarbonate level of 20 mEq/L and a low PaCO2 of 32 mm Hg. This set of values is indicative of metabolic alkalosis, which is not expected in a client with CKD.
Option D has a pH of 7.55 (alkaline) with an elevated bicarbonate level of 30 mEq/L and a low PaCO2 of 31 mm Hg. This set of values is indicative of metabolic alkalosis, which is not expected in a client with CKD.

Correct Answer is C
Explanation
The client's presentation of chest pain radiating to the left arm, sweating, shortness of breath, epigastric discomfort, cool and diaphoretic skin, tachycardia, and ST elevation on the electrocardiogram (ECG) are indicative of myocardial infarction (heart attack). These symptoms and findings are typical of acute coronary syndrome, specifically an ST-segment elevation myocardial infarction (STEMI).
Option A (Ischemic Stroke) is not the correct answer because the symptoms described in the client's presentation are primarily related to the cardiovascular system and not indicative of an ischemic stroke.
Option B (Chronic Stable Angina) is not the correct answer because chronic stable angina typically presents with chest pain on exertion or stress, and it usually subsides with rest or nitroglycerin. The client's symptoms of chest pain at rest, along with other findings, are more concerning for an acute cardiac event like a myocardial infarction.
Option D (Cardiogenic Shock) is a severe complication that can occur following a myocardial infarction, but the information provided in the scenario does not suggest that the client is in cardiogenic shock at this time. The client's blood pressure is not mentioned in the scenario, which is a crucial parameter to assess for cardiogenic shock.
Correct Answer is D
Explanation
Discharge teaching for a client with heart failure and reduced ejection fraction should prioritize education about medications that are essential in managing heart failure, such as angiotensin-converting enzyme (ACE) inhibitors.
ACE inhibitors are a class of medications commonly prescribed to heart failure patients with reduced ejection fraction. They work by dilating blood vessels, reducing the workload on the heart, and improving the heart's pumping ability. They are one of the cornerstones of heart failure management and have been shown to reduce symptoms, improve quality of life, and prolong survival in heart failure patients.
Educating the client about the benefits and effects of ACE inhibitors is crucial to promote medication adherence and ensure they understand the importance of taking this medication as prescribed. Common side effects, such as dizziness or dry cough, should also be discussed so the client knows what to expect and when to notify their healthcare provider.
While the other options may also be relevant to a client with heart failure, including starting an aerobic exercise program (A), reducing salt intake (B), and scheduling regular follow-up appointments (C), the immediate priority in discharge teaching should be about the medication regimen and the specific benefits and effects of ACE inhibitors. Other aspects of heart failure management can be addressed during the overall education and follow-up sessions.
