NCLEX 101Nuevo Documento FINAL TEST.

1.Enalapril maleate (Vasotec) is prescribed for a hospitalized client. Which assessment doesthe nurse perform as a priority before administering the medication? 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. Checking the client’s peripheral pulses, the results of the most recent potassium level, and the intake and output for the previous 24 hours are not specifically associated with this mediation. 2.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? 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. 3.A nurse on the evening shift checks a physician's prescriptions and notes that the dose of a prescribed medication is higher than the normal dose. The nurse calls the physician's answering service and is told that the physician is off for the night and will be available in the morning. The nurse should: B) Ask the answering service to contact the on-call physician Rationale: The nurse has a duty to protect the client from harm. A nurse who believes that a physician’s prescription may be in error is responsible for clarifying the prescription before carrying it out. Therefore the nurse would not administer the medication; instead, the nurse would withhold the medication until the dose can be clarified. The nurse would not wait until the next morning to obtain clarification. It is premature to call the nursing supervisor.
