Enalapril maleate (Vasotec) is prescribed for a hospitalized client. Which assessment does the nurse perform as a priority before administering the medication? A) Checking the client's blood pressure B) checking the client's peripheral pulses C) checking the most recent potassium level D) checking the client's intake and output record for the last 24 hours correct answers A) Checking the client's blood pressure Rationale--enalapril maleate is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension. One common side effect is postural hypotension. Therefore the nurse would check the client's blood pressure immediately before administering each dose. A client is scheduled to undergo an upper gastrointestinal (GI) series, and the nurse provides instructions to the client about the test. Which statement by the client indicates a need for further instruction? A) "The test will take about 30 minutes" B) "I need to fast for 8 hours before the test" C) "I need to drink citrate of magnesia the night before the test and give myself a Fleet enema on the morning of the test." D) "I need to take a laxative after the test is completed, because the liquid that I'll have to drink for the test can be constipating." correct answers C) "I need to drink citrate of magnesia the night before the test and give myself a Fleet enema on the morning of the test." Rationale An upper GI series involves visualization of the esophagus, duodenum, and upper jejunum by means of the use of a contrast medium. It involves swallowing a contrast medium (usually barium), which is administered in a flavored milkshake. Films are taken at intervals during the test, which takes about 30 minutes. No special preparation is necessary before a GI series, except that NPO status must be maintained for 8 hours before the test. After an upper GI series, the client is prescribed a laxative to hasten elimination of the barium. Barium that remains in the colon may become hard and difficult to expel, leading to fecal impaction.
