Question 1
A nurse is caring for a client receiving digoxin for heart failure who reports nausea,
vomiting, and visual halos. Which laboratory value should the nurse evaluate immediately?
A. Serum sodium level
B. Serum potassium level
C. Serum calcium level
D. Blood urea nitrogen level
🔴 Correct Answer: B. Serum potassium level
🔵 Explanation: Hypokalemia enhances the risk of digoxin toxicity because low
potassium levels increase digoxin binding to the Na+/K+ ATPase pump, leading to classic
signs of toxicity such as nausea, vomiting, and visual halos. Monitoring potassium is
critical for safety.
Question 2
A nurse is preparing to administer enoxaparin subcutaneously to a client following
orthopedic surgery. Which action demonstrates correct administration technique?
A. Rubbing the injection site vigorously after administration to enhance absorption.
B. Expelling the air bubble from the prefilled syringe prior to injection.
C. Injecting the medication into the anterolateral or posterolateral abdominal wall.
D. Aspirating for blood return prior to depressing the plunger.
🔴 Correct Answer: C. Injecting the medication into the anterolateral or
posterolateral abdominal wall.
🔵 Explanation: Enoxaparin is administered into the abdominal subcutaneous tissue, at
least 2 inches away from the umbilicus. The air bubble should not be expelled as it ensures
full dose delivery, and aspiration or rubbing causes tissue trauma and hematoma.
,Question 3
A client with type 1 diabetes mellitus is prescribed regular insulin and NPH insulin
subcutaneously at 0700. How should the nurse prepare the injection in a single syringe?
A. Draw up the NPH insulin first, followed by the regular insulin.
B. Inject air into the NPH vial, inject air into the regular vial, draw regular insulin, then
draw NPH insulin.
C. Inject air into the regular vial, inject air into the NPH vial, draw NPH insulin, then draw
regular insulin.
D. Mix the insulins in separate syringes and inject them at two different anatomical sites.
🔴 Correct Answer: B. Inject air into the NPH vial, inject air into the regular vial,
draw regular insulin, then draw NPH insulin.
🔵 Explanation: To prevent contamination of clear (short-acting/regular) insulin with
cloudy (intermediate-acting/NPH) insulin, air is injected into cloudy then clear, and
medication is drawn clear to cloudy.
Question 4
A nurse is providing discharge instructions to a client who has a new prescription for
captopril. Which adverse effect should the nurse instruct the client to report immediately?
A. Mild skin rash
B. Swelling of the tongue or lips
C. Transient metallic taste
D. Dry nonproductive cough
🔴 Correct Answer: B. Swelling of the tongue or lips
🔵 Explanation: Swelling of the tongue or lips indicates angioedema, a life-threatening
adverse reaction associated with ACE inhibitors that compromises the airway. While a dry
cough is common, angioedema requires immediate emergency intervention.
Question 5
A nurse is reviewing the medication administration record for a client receiving
spironolactone. Which dietary modification should the nurse reinforce?
A. Increase intake of dark green leafy vegetables.
B. Avoid the use of salt substitutes containing potassium chloride.
C. Consume at least three servings of dairy products daily.
D. Restrict fluids to less than 1,000 mL per day.
🔴 Correct Answer: B. Avoid the use of salt substitutes containing potassium
chloride.
🔵 Explanation: Spironolactone is a potassium-sparing diuretic. Using salt substitutes that
contain potassium increases the risk of severe hyperkalemia, which can cause lethal
cardiac dysrhythmias.
Question 6
A client who is taking warfarin for deep vein thrombosis has an International Normalized
Ratio (INR) of 5.2. The nurse notes no signs of active bleeding. Which action should the
nurse anticipate?
A. Administering protamine sulfate intravenously.
B. Administering subcutaneous filgrastim.
C. Withholding the next dose of warfarin and notifying the provider.
,D. Increasing the daily dose of warfarin.
🔴 Correct Answer: C. Withholding the next dose of warfarin and notifying the
provider.
🔵 Explanation: The therapeutic INR range for DVT treatment is typically 2.0 to 3.0. An
INR of 5.2 indicates heightened bleeding risk. Withholding the dose and consulting the
healthcare provider for guidance or Vitamin K administration is standard care.
Question 7
A nurse is administering sublingual nitroglycerin to a client experiencing acute chest pain.
What is the maximum number of doses the nurse should administer before calling
emergency services if pain persists?
A. One dose
B. Two doses
C. Three doses
D. Four doses
🔴 Correct Answer: C. Three doses
🔵 Explanation: Sublingual nitroglycerin is given one tablet every 5 minutes up to a
maximum of 3 doses. If chest pain is unrelieved 5 minutes after the first dose, emergency
services should be activated while proceeding with subsequent doses.
Question 8
A nurse is caring for a client receiving intravenous furosemide. Which manifestation
indicates that the client is experiencing an adverse reaction to the medication?
A. Tinnitus and hearing loss
B. Hyperkalemia and hypertension
C. Weight gain of 2 kg in 24 hours
D. Hypoglycemia and bradycardia
🔴 Correct Answer: A. Tinnitus and hearing loss
🔵 Explanation: Rapid intravenous administration of loop diuretics like furosemide can
cause ototoxicity, manifesting as tinnitus, vertigo, or hearing loss. Furosemide causes
hypokalemia, hypovolemia, and hypotension.
Question 9
A client with asthma is prescribed albuterol and beclomethasone metered-dose inhalers.
Which instruction should the nurse give regarding the administration sequence?
A. Administer beclomethasone first, wait 5 minutes, then administer albuterol.
B. Administer albuterol first, wait 5 minutes, then administer beclomethasone.
C. Mix both inhalations together and inhale concurrently.
D. Use beclomethasone only for acute asthma attacks.
🔴 Correct Answer: B. Administer albuterol first, wait 5 minutes, then administer
beclomethasone.
🔵 Explanation: Albuterol is a rapid-acting bronchodilator that opens the airways,
allowing the inhaled corticosteroid (beclomethasone) to penetrate deeper into the
pulmonary tissues for maximum anti-inflammatory effect.
Question 10
A nurse is instructing a client who has a new prescription for levothyroxine to treat
, hypothyroidism. When should the nurse instruct the client to take this medication?
A. Immediately before bedtime with a high-protein snack.
B. In the morning 30 to 60 minutes before breakfast with a full glass of water.
C. Mid-day with lunch to decrease gastrointestinal irritation.
D. Concurrently with calcium carbonate supplements.
🔴 Correct Answer: B. In the morning 30 to 60 minutes before breakfast with a full
glass of water.
🔵 Explanation: Levothyroxine absorption is optimized when taken on an empty stomach
in the morning. Taking it at night can cause insomnia, and calcium supplements
significantly impair its absorption.
Question 11
A nurse is monitoring a client receiving vancomycin IV for a severe methicillin-resistant
Staphylococcus aureus (MRSA) infection. The client develops flushing of the face, neck,
and chest along with pruritus. Which action should the nurse take first?
A. Stop the infusion immediately and disconnect the IV line.
B. Administer intramuscular epinephrine.
C. Slow the rate of the vancomycin infusion.
D. Apply warm compresses to the upper torso.
🔴 Correct Answer: C. Slow the rate of the vancomycin infusion.
🔵 Explanation: Flushing, erythema, and pruritus of the upper body ("Red Man
Syndrome") result from rapid histamine release associated with fast IV vancomycin
infusions. Slowing the infusion rate over 60 to 90 minutes typically resolves the symptom.
Question 12
A nurse is reviewing laboratory results for a client who is taking lithium carbonate for
bipolar disorder. Which serum level indicates a therapeutic concentration?
A. 0.2 mEq/L
B. 0.9 mEq/L
C. 2.1 mEq/L
D. 3.5 mEq/L
🔴 Correct Answer: B. 0.9 mEq/L
🔵 Explanation: The target therapeutic serum range for lithium during maintenance
therapy is 0.6 to 1.2 mEq/L. Levels above 1.5 mEq/L can cause toxicity, presenting with
coarse tremors, ataxia, and confusion.
Question 13
A client is prescribed oral prednisone daily for the management of rheumatoid arthritis.
Which instruction should the nurse include in the client's educational plan?
A. Discontinue the medication immediately if weight gain occurs.
B. Take the medication late in the evening to prevent insomnia.
C. Avoid abrupt withdrawal of the medication to prevent adrenal crisis.
D. Limit intake of protein and calcium during therapy.
🔴 Correct Answer: C. Avoid abrupt withdrawal of the medication to prevent
adrenal crisis.
🔵 Explanation: Exogenous corticosteroid therapy suppresses the hypothalamic-pituitary-
