,Section A - Foundations OF Nursing AND THE Nursing
Process
Q1.
A nurse is reviewing a provider's orders and notes that the client has a new prescription
for a medication the client reports as an allergy. Which action should the nurse take first?
A. Administer the medication and monitor B. Withhold the medication and notify the
closely for a reaction. provider of the reported allergy.
C. Ask the pharmacist to verify the allergy D. Document the allergy and administer the
before giving the dose. medication as ordered.
Correct: B - Withhold the medication and notify the provider of the reported allergy.
Rationale:The nurse must withhold the medication and contact the provider when a
prescribed drug conflicts with a reported allergy, because giving it could cause harm. Verifying
with the pharmacist or documenting does not replace the nurse's duty to stop and clarify the
order.
Why the other answers are wrong:
A. Administering a known allergen violates the nurse's duty to prevent harm.
C. Pharmacist verification is helpful but does not replace withholding the drug and notifying the
provider.
D. Documenting an allergy does not make administration of that allergen safe.

(Medication Administration).
Q2.
A client is admitted with active pulmonary tuberculosis. Which type of transmission-based
precautions should the nurse initiate?
A. Contact precautions with gown and B. Droplet precautions with a surgical mask
gloves only
C. Airborne precautions with an N95 D. Standard precautions with eye protection
respirator and negative-pressure room
Correct: C - Airborne precautions with an N95 respirator and negative-pressure room
Rationale:Tuberculosis is transmitted via airborne droplet nuclei, requiring an N95 respirator
and a negative-pressure airborne infection isolation room. Droplet and contact precautions
are insufficient for airborne pathogens.
Why the other answers are wrong:
A. Contact precautions are used for organisms spread by direct/indirect contact, not airborne

TB.
B. Droplet precautions apply to organisms like influenza or pertussis, not TB.
D. Standard precautions alone do not protect against airborne transmission.
Reference: CDC (2024). Guideline for Isolation Precautions; Potter, P. et al. (2025). Fundamentals of
Nursing, 11th Ed., Ch. 28.
Q3.
Which finding should the nurse identify as an early sign of increased intracranial pressure
in a client after a head injury?
A. Decreased level of consciousness B. Widened pulse pressure with bradycardia
C. Unilateral pupil dilation D. Decerebrate posturing
Correct: A - Decreased level of consciousness
Rationale:A change in level of consciousness is the earliest and most sensitive indicator of
increasing intracranial pressure. Cushing's triad and pupillary changes occur later as pressure
rises.
Why the other answers are wrong:
B. Widened pulse pressure with bradycardia (Cushing's triad) is a late sign.
C. Unilateral pupil dilation is a later, more ominous sign.
D. Decerebrate posturing indicates severe brainstem involvement and is a late sign.
Reference: Hinkle, J.L. & Cheever, K.H. (2022). Brunner & Suddarth's Textbook of Medical-Surgical
Nursing, 15th Ed., Ch. 65.
Q4.
A nurse is preparing to administer a medication via a nasogastric tube. Which action is
most appropriate to ensure client safety?
A. Mix the medication with the enteral B. Verify tube placement by auscultating
feeding formula. injected air.
C. Flush the tube with water before and after D. Administer all medications
each medication. simultaneously to save time.
Correct: C - Flush the tube with water before and after each medication.
Rationale:Flushing with water before and after each medication prevents clogging and drug
interactions within the tube. Auscultating injected air is no longer a reliable method for
verifying placement.
Why the other answers are wrong:
A. Mixing medications with formula can cause interactions and tube occlusion.
B. Auscultation of injected air is unreliable and not evidence-based for placement verification.
D. Administering all medications at once increases risk of interactions and clogging.
