A client who has been receiving diuretic therapy is admitted to the emergency department with a serum potassium level of 3.0 mEq/L. The nurse should alert the health care provider immediately that the client is on which medication?

Lantus insulin 24 U subcutaneously every evening

Oral digoxin (Lanoxin) 0.25 mg daily

Metoprolol (Lopressor) 12.5 mg orally daily

Ibuprofen (Motrin) 400 mg every 6 hours

Answer and Explanation

The Correct Answer is B

A. Lantus insulin does not directly affect potassium levels in the same way that digoxin does.

B. A potassium level of 3.0 mEq/L is low, and digoxin toxicity can occur when potassium levels are low, leading to an increased risk of arrhythmias. This requires immediate attention to avoid serious complications.

C. Metoprolol is a beta-blocker that does not directly cause hypokalemia and is less of an immediate concern.

D. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that could affect kidney function but does not directly impact potassium levels as significantly as digoxin.

Correct Answer is A

Explanation

A. This description is indicative of possible myocardial infarction (MI), a life-threatening emergency. Immediate evaluation and intervention, such as administering oxygen, obtaining an EKG, and providing pain relief, are crucial to prevent further damage to the heart and reduce mortality.

B. Moderate pain worse on inspiration suggests pleuritic pain, often associated with conditions like pleuritis or pulmonary embolism, which are serious but generally not as immediately life-threatening as an MI.

C. Cramping substernal pain may indicate a gastrointestinal issue, such as gastroesophageal reflux disease (GERD), which is less urgent than a potential MI.

D. A dull ache may be related to musculoskeletal or gastrointestinal issues and does not suggest the immediate need for intervention seen in MI.

A. Measurement of abdominal girth B. Auscultation of any area in the abdomen C. Palpation of the abdominal midline area D. Observation of abdominal wall movement

Correct Answer is C

Explanation

A. Measuring abdominal girth can help monitor the aneurysm.

B. Auscultation is safe and may reveal bruits associated with aneurysms.

C. Palpation of the abdominal midline area is dangerous and can risk rupturing the aneurysm, requiring further education.

D. Observation is non-invasive and safe.
