●● Enalapril maleate 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.
Answer: 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.
,●● 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.".
Answer: 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: No special preparation is necessary before a GI series, except
that NPO (nothing by mouth) status must be maintained for 8 hours
before the test.
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. 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.
, ●● A nurse on the evening shift checks a primary health care provider's
prescriptions and notes that the dose of a prescribed medication is higher
than the normal dose. The nurse calls the primary health care provider's
answering service and is told that the primary health care provider is off
for the night and will be available in the morning. What should the nurse
do next?
A. Call the nursing supervisor
B. Ask the answering service to contact the on-call primary health care
provider
C. Withhold the medication until the primary health care provider can be
reached in the morning
D. Administer the medication but consult the primary health care
provider when he becomes available.
Answer: B. Ask the answering service to contact the on-call primary
health care provider
Rationale: The nurse has a duty to protect the client from harm.
A nurse who believes that a primary health care provider'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.
