1. A client with heart failure is prescribed furosemide. Which laboratory value
should the nurse monitor most closely to evaluate the effectiveness of this
medication?
A. Serum sodium
B. Serum potassium
C. Serum creatinine
D. Daily weight
Correct Answer: D. Daily weight
Rationale: Daily weight is the most sensitive and accurate indicator of fluid volume
status. A decrease in weight reflects effective diuresis and reduction of fluid
overload. While serum electrolytes and creatinine are important to monitor for
adverse effects, they do not directly measure the therapeutic effectiveness of the
diuretic in removing excess fluid.
2. A nurse is caring for a client who is post-operative following a total hip
arthroplasty. Which finding requires immediate intervention?
A. Pain of 4 on a 0-10 scale at the surgical site
B. Mild erythema around the incision
C. Shortness of breath and chest pain
D. A temperature of 99.8°F (37.7°C)
Correct Answer: C. Shortness of breath and chest pain
Rationale: Shortness of breath and chest pain in a post-operative client are classic
signs of a pulmonary embolism, a life-threatening complication of major surgery.
,This finding warrants immediate intervention. Mild pain, localized erythema, and a
low-grade fever are expected findings in the early post-operative period and should
be monitored but are not the priority.
3. A client with a new diagnosis of type 1 diabetes mellitus is learning to self-
administer insulin. Which action by the client indicates a correct understanding
of the teaching?
A. Storing the unopened insulin vials in the freezer
B. Rotating injection sites within the same anatomic region
C. Massaging the injection site after administering the insulin
D. Using the same needle twice to reduce cost
Correct Answer: B. Rotating injection sites within the same anatomic region
Rationale: Rotating injection sites within the same anatomic region (e.g., abdomen)
promotes consistent absorption and prevents lipohypertrophy. Insulin should not be
frozen, sites should not be massaged as it can alter absorption, and needles are for
single-use only to prevent infection and tissue damage.
4. The healthcare provider prescribes 500 mg of acetaminophen for a client
with a fever. The available medication is 250 mg/5 mL. How many mL should
the nurse administer?
A. 5 mL
B. 10 mL
C. 15 mL
D. 20 mL
Correct Answer: B. 10 mL
Rationale: Using the formula (Desired / Have) x Quantity: (500 mg / 250 mg) x 5
mL = 2 x 5 mL = 10 mL. The nurse should administer 10 mL to deliver the
prescribed 500 mg dose.
,5. A nurse is providing education to a prenatal client about nutritional needs
during pregnancy. Which statement by the client indicates a need for further
teaching?
A. "I should increase my folic acid intake to prevent neural tube defects."
B. "I need to consume an additional 300-500 calories per day during the third
trimester."
C. "I can continue to eat deli meats as long as I heat them until they are steaming
hot."
D. "I should avoid all types of fish to prevent mercury exposure."
Correct Answer: D. "I should avoid all types of fish to prevent mercury exposure."
Rationale: It is not necessary to avoid all fish. Pregnant clients should avoid fish
high in mercury (e.g., shark, swordfish, king mackerel) but can safely consume up to
12 ounces per week of low-mercury fish like salmon, shrimp, and tuna. The other
statements are accurate: folic acid is crucial, caloric needs increase in the third
trimester, and deli meats should be reheated to steaming to prevent listeriosis.
6. During a sterile procedure, a nurse drops a sterile gauze pad onto the floor.
What is the most appropriate action?
A. Pick up the gauze and use it if it appears clean.
B. Discard the gauze and obtain a new sterile one.
C. Wipe the gauze with an alcohol swab and then use it.
D. Use the gauze, but document the incident for quality improvement.
Correct Answer: B. Discard the gauze and obtain a new sterile one.
Rationale: Any item that falls below the waist level or touches an unsterile surface
is considered contaminated. To maintain surgical asepsis, the nurse must discard
the contaminated item and obtain a new sterile gauze pad. Compromising sterility
increases the risk of infection.
, 7. A client with chronic obstructive pulmonary disease (COPD) is receiving
oxygen at 2 L/min via nasal cannula. Which assessment finding indicates that
the current oxygen therapy is effective?
A. Client's respiratory rate is 22 breaths per minute.
B. Client's pulse oximetry reading is 92%.
C. Client reports a decrease in dyspnea.
D. Client's arterial blood gas shows a PaO2 of 75 mmHg.
Correct Answer: D. Client's arterial blood gas shows a PaO2 of 75 mmHg.
Rationale: While all options suggest improvement, an ABG is the most objective and
definitive measure of oxygenation. A PaO2 of 75 mmHg indicates adequate
oxygenation and is the gold standard for evaluating the effectiveness of oxygen
therapy. A pulse oximetry reading of 92% is acceptable, but ABG provides a more
comprehensive assessment.
8. A nurse is preparing to administer a blood transfusion to a client. Which
action is most important to prevent a transfusion reaction?
A. Verify the client's identity and the blood product with another licensed nurse.
B. Use a 20-gauge or larger intravenous catheter for the transfusion.
C. Infuse the blood product over a 4-hour period.
D. Assess the client's vital signs every 15 minutes for the first hour.
Correct Answer: A. Verify the client's identity and the blood product with another
licensed nurse.
Rationale: The most critical step in preventing a transfusion reaction is the
verification of the client's identity and the compatibility of the blood product. This
two-nurse verification process ensures that the right blood is given to the right
client. The other actions are also important but are secondary to this primary safety
measure.
