,Unit 1: Pharmacological Principles and Safety (Questions 1-20)
Question 1
A nurse is preparing to administer a medication. Which of the following actions
should the nurse take FIRST?
A) Document the medication administration
B) Perform the three checks of medication administration
C) Assess the client's vital signs
D) Verify the client's allergy status
Correct ,,answer,,,: B
Rationale: Before administering any medication, the nurse must perform the three
checks of medication administration (checking the medication against the MAR at
three different times: when removing from storage, when preparing, and before
administration at the bedside) to ensure patient safety . While allergy verification
(D) and vital sign assessment (C) are also important, the three checks are
foundational to medication safety and should occur before other actions.
Question 2
A client is prescribed aluminum hydroxide for peptic ulcer disease. Which
statement by the client demonstrates an understanding of the action of the
medication?
, A) "It decreases the production of gastric secretions."
B) "It produces an adherent barrier over the ulcer."
C) "It helps maintain a gastric pH of 3.5 or above."
D) "It slows down gastric motor activity."
Correct ,,answer,,,: C
Rationale: Aluminum hydroxide is an antacid that neutralizes gastric acid, helping
to maintain a gastric pH of 3.5 or above . It does not decrease gastric secretion
production (A), that is the action of H2 antagonists or PPIs. It does not produce an
adherent barrier (B), which is the action of sucralfate. It does not slow gastric
motor activity (D).
Question 3
A nurse is assessing a client who is receiving chloramphenicol. Which of the
following findings is an adverse effect of this medication?
A) Ototoxicity
B) Hypertension
C) Anxiety
D) Ecchymosis
Correct ,,answer,,,: D
Rationale: Chloramphenicol can cause thrombocytopenia, which presents with
ecchymosis (bruising), petechiae, and bleeding . Ototoxicity (A) is associated with
aminoglycosides and loop diuretics, not chloramphenicol. Hypertension (B) and
anxiety (C) are not typical adverse effects of this medication.
