D.An 84-year-old patient with diabetes, heart failure, and hypertension who takes seven

Rationale: Adverse events are more common in older adults and the very young, in
patients with severe illness, and in those who are taking multiple drugs.

A patient is prescribed a medication that is potentially hepatotoxic. Before administering
the medication, it is most important for the nurse to assess what?

A.Blood urea nitrogen and serum creatinine
B.Aspartate aminotransferase and alanine aminotransferase
C.Prolonged QT interval on the electrocardiogram
D.Serum potassium, serum sodium, and serum magnesium correct answers
B.Aspartate aminotransferase and alanine aminotransferase

Rationale: The nurse should assess the liver function tests of patients who are taking
hepatotoxic drugs. When liver cells are injured, two liver enzymes (aspartate
aminotransferase [AST] and alanine aminotransferase [ALT]) will be elevated.

The healthcare provider writes a medication order that the nurse cannot read. What
should the nurse do?

A.Consult with the charge nurse to verify the order.
B.Discuss the order with the pharmacist.
C.Check with the patient to determine the correct medication.
D.Contact the prescriber to clarify the order. correct answers D.Contact the prescriber
to clarify the order.

Rationale: The nurse should contact the prescriber to clarify the order.

The nurse reviews a patient's admission orders written by the healthcare provider.
Which medication order should the nurse question?

, A.Cyanocobalamin 100 mcg intramuscularly every month
B.MSO4 2.0 mg IV every 2 to 4 hours as needed for pain
C.Levothyroxine 75 mcg orally every morning
D.Enoxaparin 40 mg subQ every day for 7 days correct answers B.MSO4 2.0 mg IV
every 2 to 4 hours as needed for pain

Rationale: Miscommunication is a common cause of medication errors. To help reduce
errors, a list of abbreviations, symbols, and dose designations that should not be used
is available. "MSO4" should be written as "morphine sulfate," and a trailing zero should
not be used after a final decimal point. The medication order should be written as
"Morphine sulfate 2 mg IV every 2 to 4 hours as needed for pain."
