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
Among the given options, the assessment data that indicate the need for immediate action by the nurse is a blood pressure of 103/54 mm Hg. This blood pressure reading indicates hypotension, which can be concerning for a post-angioplasty patient.
Angioplasty with stent placement is an invasive procedure, and patients may experience fluctuations in blood pressure during the immediate post-operative period. Hypotension after angioplasty can be a sign of inadequate cardiac output, which may be due to issues like bleeding, fluid loss, or heart dysfunction. Inadequate blood pressure can lead to decreased perfusion to vital organs, including the heart itself, and can be life-threatening.
Options A, B, and D are also important to address:
A) Heart rate 102 beats/min: A heart rate of 102 beats per minute may indicate tachycardia, which can be expected after a procedure like angioplasty. However, it is not as urgent of a concern as hypotension, and it may be a normal compensatory response to the body's stress.
B) Report of chest pain: Chest pain after angioplasty can be common, but it should be evaluated further to ensure it is not indicative of complications such as coronary artery spasms, clot formation, or restenosis of the treated artery. While this is an important issue to address, it does not take precedence over hypotension.
D) Pedal pulses 1+ bilaterally: This finding suggests that the peripheral pulses in the feet are weak, and it could be related to the patient's medical condition, medications, or positioning. While it requires attention, it is not an immediate threat to the patient's life compared to severe hypotension.
Therefore, the nurse should prioritize assessing and addressing the low blood pressure to prevent further complications and ensure the patient's stability. The nurse should promptly notify the healthcare provider and implement appropriate interventions, such as administering intravenous fluids, to increase blood pressure to a safe level.
Correct Answer is A
Explanation
In a patient with acute decompensated heart failure (ADHF), the priority nursing assessment is to auscultate lung sounds. ADHF is characterized by the sudden worsening of heart failure symptoms, which may include pulmonary congestion and fluid accumulation in the lungs. Assessing lung sounds helps to identify signs of pulmonary edema, which is a serious complication of ADHF.
The nurse should listen for crackles or rales, which are abnormal lung sounds caused by the presence of fluid in the alveoli. These findings suggest that the patient is experiencing fluid overload and inadequate gas exchange in the lungs. Prompt recognition of pulmonary edema allows for early intervention, such as administering diuretics or other medications, to relieve fluid overload and improve respiratory function.
While the other options (B) Facial swelling, (C) Level of anxiety, and (D) Intake and output, are important assessments in a patient with heart failure, they are not the priority in a patient with manifestations of acute decompensated heart failure. The priority is to assess for signs of respiratory
distress and pulmonary congestion, as these can quickly lead to respiratory failure and life threatening complications.
