Q

A client with a history of hypertension presents to the emergency department reporting a severe headache for three days. The triage nurse obtains a blood pressure of 231/187 mmHg and the client’s creatinine is 2.5 mg/dL. After establishing intravenous access, the nurse notifies the healthcare provider.

Q

A client presents to the ER with palpitations after returning from a vacation. They state that yesterday, they consumed a moderate amount of alcohol and inhaled cocaine. The client has premature atrial contractions (PACs) on their electrocardiogram. What is the most likely cause of the client’s arrhythmia?

Q

The cardiac nurse is caring for several clients who are each prescribed an angiotensin-converting enzyme (ACE) inhibitor. The nurse should hold the next dose and call the provider to discuss the prescription for which client?
A. Adult client recently prescribed spironolactone for heart failure
B. Elderly client diagnosed with acute myocardial infarction (MI)
C. Female client with a potassium level of 4.0 mEq/L
D. Adult male with a blood pressure of 142/88 mmHg

A

A. Adult client recently prescribed spironolactone for heart failure

ACE inhibitors decrease potassium excretion in the urine, which can lead to hyperkalaemia. So, it is important for clients who are taking ACE inhibitors to avoid taking potassium sparing diuretics, like spironolactone. The nurse should hold the next dose and contact the provider to discuss the prescription for this client.
