The nurse identifies that a patient with chronic kidney disease is at risk for which electrolyte disturbance?

Pericarditis is inflammation of the pericardium, the sac-like membrane surrounding the heart. It can cause chest pain, which is often worsened by deep breathing or coughing. The goal of treatment for pericarditis is to reduce inflammation and relieve pain.

In this case, the client's pain level is reported as 6 out of 10. As per the PRN (as-needed) medication options given:

C) Oral ibuprofen (Motrin) 600 mg: Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) and can help reduce inflammation and relieve pain in cases of pericarditis. It is an appropriate choice for this client's pain level of 6 out of 10.

A) IV morphine sulfate 4 mg: IV morphine is a potent opioid analgesic and may be appropriate for severe pain. However, in this case, the client's pain level is moderate (6 out of 10), and it is not the first-line medication for pericarditis pain.

B) Oral acetaminophen (Tylenol) 650 mg: Acetaminophen is a mild analgesic and antipyretic that can be effective for mild to moderate pain. However, in this situation, the client's pain is moderate (6 out of 10), and acetaminophen alone may not provide adequate relief for pericarditis pain.

D) Fentanyl 1 mg IV: Fentanyl is another potent opioid analgesic. However, similar to morphine, it may be more appropriate for severe pain, not moderate pain like in this scenario.

Based on the client's pain level and the goal of reducing inflammation, the most appropriate PRN medication for the nurse to give is oral ibuprofen (Motrin) 600 mg.

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.
