1. A nurse is caring for a client who refuses a blood transfusion due to
religious beliefs. The client is alert and oriented. What is the nurse's priority
action?

A. Notify the provider immediately

B. Document the refusal and contact the ethics committee

C. Administer the transfusion to save the client's life

D. Ask the family to convince the client to accept treatment

E. Respect the client's decision and document the informed refusal

Correct Answer: E. Respect the client's decision and document the
informed refusal

EXPERT RATIONALE: An alert and oriented adult client has the legal and ethical
right to refuse any treatment, including blood transfusions, regardless of the
reason. The nurse must respect client autonomy, document the refusal thoroughly,
and notify the provider. Overriding a competent client's decision violates their
rights.

,2. A charge nurse is delegating tasks to an unlicensed assistive personnel
(UAP). Which task is appropriate to delegate?

A. Assessing a client's wound for signs of infection

B. Administering oral medications to a stable client

C. Teaching a client how to perform colostomy care

D. Measuring and recording intake and output for a stable client

E. Evaluating a client's response to pain medication

Correct Answer: D. Measuring and recording intake and output for a stable
client

EXPERT RATIONALE: UAPs can perform tasks that do not require clinical
judgment, such as measuring and recording intake and output. Assessment,
medication administration, teaching, and evaluation require nursing judgment and
cannot be delegated to a UAP.



3. A nurse is reviewing a client's medical record and notices a discrepancy in
the medication order. What is the appropriate first action?

A. Administer the medication as written

B. Ask another nurse to verify the order

C. Contact the prescribing provider to clarify the order

D. Hold the medication and document the discrepancy

E. Check the Physician's Desk Reference for guidance

Correct Answer: C. Contact the prescribing provider to clarify the order

EXPERT RATIONALE: When a nurse identifies a discrepancy in a medication
order, the priority is to contact the prescribing provider to clarify before
administering. This ensures client safety and prevents medication errors.

,4. A nurse is preparing to perform hand hygiene. In which situation is the use
of an alcohol-based hand rub CONTRAINDICATED?

A. After removing gloves

B. Before and after client contact

C. When hands are visibly soiled with blood

D. Before performing an invasive procedure

E. After touching objects in the client's environment

Correct Answer: C. When hands are visibly soiled with blood

EXPERT RATIONALE: Alcohol-based hand rubs are effective for most situations
but are not sufficient when hands are visibly soiled with blood, body fluids, or other
organic material. In these cases, soap and water must be used.



5. A nurse manager is reviewing staff assignments. Which client should be
assigned to the most experienced nurse?

A. A client with stable chronic obstructive pulmonary disease

B. A client scheduled for discharge teaching on diabetes management

C. A client who returned from surgery 2 hours ago and is reporting increased
pain

D. A client requesting assistance with morning hygiene

E. A postpartum client on the first day after vaginal delivery

Correct Answer: C. A client who returned from surgery 2 hours ago and is
reporting increased pain

EXPERT RATIONALE: A postoperative client reporting increased pain 2 hours
after surgery requires the highest level of nursing assessment to rule out
complications such as internal bleeding, wound dehiscence, or inadequate pain
management. This client needs the most experienced nurse.

, 6. A nurse is caring for a client under protective (reverse) isolation. Which
action by a visitor requires intervention?

A. Washing hands upon entering the room

B. Wearing a mask upon entering the room

C. Bringing fresh flowers and a fruit basket for the client

D. Wearing a gown before entering the room

E. Limiting the visit to 30 minutes

Correct Answer: C. Bringing fresh flowers and a fruit basket for the client

EXPERT RATIONALE: Clients in protective isolation are immunocompromised.
Fresh flowers and raw fruits can harbor microorganisms, including fungi and
bacteria, that can cause serious infections in immunocompromised clients. These
items are contraindicated.



7. A nurse is preparing to administer medications to four clients. Which client
should the nurse assess first?

A. A client who reports constipation and has not had a bowel movement in 2 days

B. A client with a potassium level of 3.8 mEq/L requesting a snack

C. A client receiving IV heparin who reports sudden onset of severe headache

D. A client who is 1 day postoperative and requests pain medication

E. A client with type 2 diabetes whose blood glucose is 180 mg/dL

Correct Answer: C. A client receiving IV heparin who reports sudden onset
of severe headache

EXPERT RATIONALE: Sudden onset of severe headache in a client receiving
heparin is a potential sign of intracranial hemorrhage, a life-threatening
complication. This client must be assessed immediately using the ABC and priority
framework.
