Nokea
The nurse is caring for a 68-year-old client in the emergency department.
Nurses' Notes,
Emergency Department
1020:
The client reports shortness of breath, a 2-lb weight gain over the past week, and lower extremity swelling. The client
reports slight chest discomfort during activity that is relieved with rest. Medical history is significant for hypertension.
myocardial infarction, heart failure, coronary artery disease, and chronic stable angina. Current medications include
metoprolol, furosemide, potassium chloride, lisinopril, and aspirin. The client takes all medications as prescribed except
one; he states, "I do not take that water pill because I got tired of having to go to the bathroom all the time."
S1 and S2 are present; a prominent S3 is heard. Respirations are labored with inspiratory crackles in the middle and at the
base of the lungs. The abdomen is soft and nontender with normoactive bowel sounds. There is 3+ pitting edema in the
bilateral lower extremities.

The nurse has reviewed the information from the Laboratory Results. Complete the following sentence/sentences by choosing from the list/lists of options.The nurse should prioritize interventions to treat ------------ due to the risk of ---------------------.
Correct Answer: A,B
Rationale: The client's laboratory results show hyperkalemia (ie, high potassium) and decreased kidney function, seen as elevated BUN and creatinine.
The kidneys balance potassium levels by eliminating excess potassium through urine. Clients with heart failure (HF) are at an increased risk fo
hyperkalemia due to poor kidney perfusion from decreased cardiac output and medication adverse effects. This client's decreased kidney
function and home medications, including lisinopril (ACE inhibitor) and supplemental potassium chloride, all increase the risk of hyperkalemia.
Because potassium is responsible for myocardial cell repolarization, hyper- or hypokalemia may lead to life-threatening dysrhythmias.
Therefore, the nurse should prioritize interventions to treat hyperkalemia due to the risk of dysrhythmias.
