Exams – Featuring Actual Exams, Expertly Explained
1. A nurse is preparing to administer digoxin to a client with heart failure. Before giving
the medication, which assessment finding requires the nurse to withhold the dose and
notify the provider?
A) Blood pressure 130/80 mm Hg
B) Apical pulse 52 beats per minute
C) Respiratory rate 18 breaths per minute
D) Serum potassium 3.0 mEq/L
The answer is: B) Apical pulse 52 beats per minute
Explanation:
Digoxin can cause bradycardia, so the nurse must assess the apical pulse before
administration. If the pulse is below 60 beats per minute, the medication should be
withheld and the provider notified. Although low potassium increases digoxin toxicity risk,
the immediate concern for withholding is the low heart rate. Monitoring vital signs is
essential to prevent adverse effects. Administering digoxin with a slow heart rate could
worsen bradycardia and lead to severe complications such as heart block.
2. A nurse is caring for a client who has just returned from surgery with an indwelling
urinary catheter. Which action should the nurse take to prevent catheter-associated
urinary tract infection (CAUTI)?
A) Irrigate the catheter daily with sterile water
B) Keep the drainage bag below the level of the bladder
C) Disconnect the catheter from the drainage tubing to clean it
D) Empty the drainage bag only when it is completely full
The answer is: B) Keep the drainage bag below the level of the bladder
Explanation:
Keeping the drainage bag below the bladder level prevents backflow of urine into the bladder,
which reduces the risk of infection. Irrigating the catheter daily is generally not recommended
unless prescribed. Disconnecting the catheter increases infection risk by breaking the closed
system. Emptying the bag only when full can lead to urine stasis and infection; it should be
emptied regularly to prevent this. Proper catheter care is vital to reduce CAUTI and improve
client outcomes.

3. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which
laboratory result requires immediate intervention by the nurse?
A) Blood glucose 320 mg/dL
B) Serum potassium 2.8 mEq/L
C) Arterial pH 7.28
D) Serum bicarbonate 18 mEq/L
The answer is: B) Serum potassium 2.8 mEq/L
Explanation:
Hypokalemia in DKA is life-threatening because potassium shifts back into cells when
insulin therapy begins, potentially causing severe cardiac dysrhythmias. The nurse must
notify the provider immediately to start potassium replacement before insulin
administration. While hyperglycemia and acidosis are significant, potassium levels require
urgent correction. Monitoring electrolytes closely during DKA treatment prevents
complications and improves client safety.
4. A nurse is teaching a client with chronic obstructive pulmonary disease (COPD) about
pursed-lip breathing. Which statement by the client indicates correct understanding?
A) “I should breathe in quickly through my mouth.”
B) “I need to hold my breath after inhaling.”
C) “I should breathe out slowly through my pursed lips.”
D) “I should breathe out quickly through my nose.”
The answer is: C) “I should breathe out slowly through my pursed lips.”
Explanation:
Pursed-lip breathing helps slow expiration, preventing airway collapse and improving gas
exchange in clients with COPD. Breathing out slowly through pursed lips increases airway
pressure and prolongs exhalation. Breathing in quickly or holding breath is not recommended, as
it can worsen air trapping. This technique decreases dyspnea and promotes better oxygenation.
Correct client understanding supports better disease management and symptom control.
5. A nurse is caring for a client who is postoperative following abdominal surgery. The
client reports sudden shortness of breath and chest pain. What is the nurse’s priority
action?
A) Administer prescribed pain medication
B) Encourage the client to cough and deep breathe
C) Elevate the head of the bed and assess respiratory status
D) Notify the surgical provider immediately
, 4
The answer is: C) Elevate the head of the bed and assess respiratory status
Explanation:
Sudden shortness of breath and chest pain in a postoperative client may indicate a pulmonary
embolism or other serious respiratory complication. Elevating the head of the bed improves
oxygenation and allows for better respiratory assessment. The nurse must assess the client’s
respiratory status immediately to guide further interventions. Notifying the provider is important
but follows initial assessment and stabilization. Administering pain medication without
assessment can mask symptoms.
6. A nurse is planning care for a client with a pressure ulcer on the sacrum. Which
intervention should the nurse include to promote healing?
A) Massage the area around the ulcer daily
B) Use a donut-shaped cushion when sitting
C) Reposition the client every 2 hours
D) Apply heat packs to the ulcer
The answer is: C) Reposition the client every 2 hours
Explanation:
Repositioning the client every 2 hours relieves pressure and promotes circulation to the affected
area, which is essential for pressure ulcer healing. Massaging the skin around the ulcer can cause
tissue damage and should be avoided. Donut cushions can cause uneven pressure distribution and
worsen tissue injury. Heat packs may increase inflammation and are contraindicated. Frequent
repositioning helps prevent further breakdown and supports tissue repair.
7. A nurse is teaching a client about the use of a metered-dose inhaler (MDI). Which
instruction should the nurse include?
A) Hold your breath for 10 seconds after inhalation
B) Shake the inhaler after each puff
C) Exhale deeply before using the inhaler
D) Rinse your mouth after using the inhaler
The answer is: D) Rinse your mouth after using the inhaler
Explanation:
Rinsing the mouth after using an MDI, especially corticosteroid inhalers, prevents oral thrush
