Examination
Question 1: The nurse is caring for a client receiving a blood transfusion
who develops chills, fever, and low back pain. Which action should the
nurse take FIRST?
Answer: C) Stop the transfusion immediately.
Rationale: These symptoms indicate a possible hemolytic transfusion
reaction, which can be life-threatening. The priority action is to stop the
transfusion immediately, maintain IV access with new tubing, and notify the
healthcare provider and blood bank. Slowing the infusion, administering
antihistamines, or notifying the provider without stopping the transfusion
would delay critical intervention .
,Question 2: The nurse is performing a sterile dressing change. Which
action breaks sterile technique?
Answer: C) Reaching across the sterile field to obtain an item.
Rationale: Reaching across the sterile field contaminates the field as non-
sterile arms pass over sterile items. The nurse should reach around the
edges of the field. Opening the sterile package away from the body, placing
items within the 1-inch border, and keeping objects above waist level all
maintain sterility .
Question 3: A client with COPD has an oxygen saturation of 88%. Which
oxygen delivery device should the nurse use?
Answer: D) Venturi mask.
Rationale: The Venturi mask delivers the most precise oxygen
concentration and is preferred for clients with COPD who are at risk for
carbon dioxide retention. The precise FiO2 delivery allows for careful
titration to maintain adequate oxygenation without suppressing the
hypoxic drive .
Question 4: A client who is postoperative day 1 following abdominal
surgery has not had a bowel movement. Which assessment finding should
the nurse prioritize?
Answer: C) Absence of bowel sounds.
Rationale: Absence of bowel sounds postoperatively may indicate ileus or
obstruction, which requires immediate attention. While abdominal
distention, nausea/vomiting, and client reports are important, absent bowel
sounds suggest a potentially serious complication requiring prompt
intervention .
,Question 5: When inserting an indwelling urinary catheter, which action is
most important for the nurse to maintain?
Answer: B) Maintaining sterile technique throughout the procedure.
Rationale: Indwelling catheter insertion is an invasive procedure that
introduces a foreign body into the sterile bladder. Strict sterile technique is
required from opening the kit through inflation to prevent catheter-
associated urinary tract infection (CAUTI), a major hospital-acquired
infection .
Question 6: A client with terminal cancer tells the nurse, "I'm afraid of
dying in pain." Which response is most therapeutic?
Answer: B) "Tell me more about your fears."
Rationale: This open-ended response encourages the client to express
feelings and validates their concerns. It allows for exploration of specific
fears and demonstrates therapeutic communication. Dismissing concerns or
providing false reassurance is not therapeutic .
Question 7: The nurse is teaching a client about self-administration of
insulin. Which site has the fastest absorption rate?
Answer: A) Abdomen.
Rationale: The abdomen has the fastest insulin absorption rate due to
increased blood flow and consistent subcutaneous tissue. Absorption rates
from fastest to slowest are: abdomen > arm > thigh > buttocks .
Question 8: A client is experiencing a seizure. Which action should the
nurse take?
Answer: B) Loosen restrictive clothing.
, Rationale: Loosening restrictive clothing protects the airway and prevents
injury during the seizure. Never insert objects into the mouth (could cause
injury), restrain extremities (could cause fractures), or place supine (could
cause aspiration) .
Question 9: The nurse is auscultating a client's breath sounds and hears
crackles in the lung bases. This finding is most consistent with which
condition?
Answer: C) Pulmonary edema.
Rationale: Crackles (rales) in the lung bases are characteristic of pulmonary
edema and heart failure. Fine crackles indicate fluid in the alveoli, while
coarse crackles may indicate secretions in larger airways .
Question 10: Which intervention is most effective in preventing falls in a
hospitalized elderly client?
Answer: A) Keeping the bed in the lowest position.
Rationale: Keeping the bed in the lowest position reduces injury risk if a fall
occurs and makes it easier for the client to get in and out of bed safely.
Other important interventions include using bed alarms, ensuring adequate
lighting, and keeping frequently used items within reach .
Question 11: When preparing to insert a Foley catheter in a female client,
which position is most appropriate?
Answer: B) Dorsal recumbent.
Rationale: The dorsal recumbent position (supine with knees flexed and
feet flat) provides optimal visualization of the urethral meatus. Sims
position is used for enemas or rectal exams, and lithotomy provides better
visualization but is more invasive .
