1. A nurse is caring for a client with a history of depression who is currently experiencing a
situational crisis. Which of the following actions should the nurse take first?
A. Encourage the client to verbalize feelings about the crisis.
B. Administer an antidepressant medication as prescribed.
C. Refer the client to a psychiatrist for immediate evaluation.
D. Teach the client relaxation techniques.
Answer: D
Rationale: In a situational crisis, the priority is to help the client manage acute anxiety and regain a
sense of control. Relaxation techniques are a non-invasive, immediate intervention that can reduce
physiological arousal and promote coping, making them the first step before medication, referral, or
in-depth discussion.
2. A patient with acute respiratory distress syndrome (ARDS) is receiving mechanical ventilation
with the following settings: FiO2 0.8, PEEP 15 cm H2O, and tidal volume 6 mL/kg. The plateau
pressure is 35 cm H2O. Which adjustment should the nurse anticipate to reduce the risk of
ventilator-induced lung injury?
A. Increase tidal volume to 8 mL/kg
B. Increase FiO2 to 1.0
C. Increase PEEP to 20 cm H2O
D. Decrease tidal volume to 4 mL/kg
Answer: D
Rationale: Plateau pressure >30 cm H2O is associated with barotrauma. Decreasing tidal volume
(lung-protective ventilation) reduces plateau pressure. Increasing PEEP may improve oxygenation but
can increase plateau pressure. FiO2 increase does not reduce injury.
3. A nurse is caring for an older adult client who has prescriptions for multiple medications. Which
of the following factors should the nurse identify as an age-related change that increases the risk
for adverse effects from medications?
A. Increased gastric motility
B. Elevated hepatic metabolism
C. Prolonged medication half-life
D. Enhanced renal excretion
Answer: C
Rationale: Prolonged medication half-life is an age-related change due to reduced liver and kidney
function, leading to slower drug clearance and increased risk of toxicity. The other options describe
changes that would decrease drug levels and risk, not increase them.

,4. A patient with a history of major depressive disorder is started on phenelzine. The nurse
provides dietary teaching. Which meal selection indicates a need for further teaching?
A. Turkey sandwich on whole wheat bread with lettuce and tomato.
B. Grilled chicken salad with vinaigrette dressing and a glass of water.
C. Cheese pizza with pepperoni and a glass of red wine.
D. Vegetable stir-fry with tofu and steamed rice.
Answer: C
Rationale: Phenelzine is an MAOI that requires avoidance of tyramine-rich foods. Cheese, pepperoni,
and red wine are high in tyramine and can cause hypertensive crisis. Options A, B, and C are low in
tyramine (milkshake is generally safe; green tea has minimal tyramine).
5. A nurse is assessing a client who is receiving packed red blood cells. Which of the following
findings suggests fluid overload?
A. Dyspnea
B. Hypotension
C. Bradycardia
D. Decreased jugular venous pressure
Answer: A
Rationale: Dyspnea is a key indicator of fluid overload due to pulmonary congestion. Hypotension,
bradycardia, and decreased jugular venous pressure are not associated with fluid overload; they may
indicate hypovolemia or other conditions.
6. A patient with chronic kidney disease stage 4 is admitted with hyperkalemia (potassium 6.8
mEq/L) and peaked T waves on the cardiac monitor. The nurse prepares to administer intravenous
calcium gluconate. Which action is most critical before administration?
A. Obtain a serum magnesium level.
B. Assess the patient's blood pressure.
C. Check the patient's digoxin level.
D. Administer sodium bicarbonate first.
Answer: C
Rationale: Calcium gluconate can potentiate digoxin toxicity, so checking the digoxin level is critical.
While verifying IV access and ECG are important, the most critical is assessing digoxin level to avoid
fatal arrhythmias. Serum calcium level is less relevant.
7. A nurse in a clinic is assessing a 6-month-old infant. Which of the following findings should the
nurse report to the provider?
A. Closed anterior fontanel
B. Social smile in response to the nurse
C. Ability to track a moving object with the eyes
D. Presence of a positive Babinski reflex
Answer: A
Rationale: posterior -closes around 2 months, anterior at 12-18 mths

,8. A patient with acute pancreatitis suddenly develops severe epigastric pain, hypotension, and
bluish discoloration around the umbilicus. Which pathophysiological mechanism best explains this
finding?
A. Retroperitoneal hemorrhage from pancreatic enzyme autodigestion of peripancreatic vessels
B. Intra-abdominal infection leading to septic shock and cutaneous necrosis
C. Disseminated intravascular coagulation with subcutaneous bleeding
D. Portal hypertension causing dilation of periumbilical veins and ecchymosis
Answer: A
Rationale: The bluish periumbilical discoloration (Cullen sign) in acute pancreatitis results from
retroperitoneal hemorrhage due to autodigestion of peripancreatic vessels by activated pancreatic
enzymes, leading to blood tracking along fascial planes to the umbilicus.
9. A nurse is counseling a group of clients from a town that was affected by a hurricane 6 months
ago. Which of the following clients should the nurse initiate a referral to assess for the presence of
posttraumatic stress disorder? (Select all that apply.)
A. A client who states they have been avoiding driving through the flooded areas of town.
B. A client who has frequent nightmares about the hurricane.
C. A client who expresses anger toward emergency responders for their delayed arrival.
D. A client who reports feeling sad and tearful when discussing the hurricane.
Answer: B
Rationale: Frequent nightmares about a traumatic event are a classic symptom of PTSD, specifically
re-experiencing. The other options describe common post-disaster reactions (sadness, anger, avoidance)
that do not necessarily indicate PTSD without additional criteria such as duration, intensity, or
functional impairment.
10. A nurse is assessing a client who has a prescription for hydrocodone as needed (PRN). Which of
the following adverse effects should the nurse identify as the priority for withholding the
medication and notifying the provider?
A. Constipation
B. Drowsiness
C. Nausea
D. Hypotension
Answer: D
Rationale: Hydrocodone can cause hypotension, which may indicate a serious adverse effect requiring
immediate action to prevent harm. While constipation, drowsiness, and nausea are common side effects,
they are not typically urgent enough to warrant withholding the medication and notifying the provider.
11. A nurse is preparing to administer a blood transfusion to a client. The client's vital signs are:
BP 100/60 mm Hg, HR 110/min, RR 22/min, temperature 37.1°C (98.8°F). Which action is most
important for the nurse to take to prevent a transfusion reaction?
A. Administer an antipyretic to prevent febrile reaction.
B. Monitor vital signs every 15 minutes during the first hour.
Page 3
, C. Verify the client's identity using two identifiers and check the blood product with another nurse.
D. Prime the blood tubing with normal saline and maintain a slow rate.
Answer: C
Rationale: The most critical step to prevent a transfusion reaction is proper identification and
verification of the blood product with the client using two identifiers, as most reactions result from
clerical errors. While other steps (priming tubing, slow start, premedication) are important, they do not
prevent ABO incompatibility.
12. A nurse is reviewing the cardiac rhythm of a client on continuous ECG monitoring. Which of
the following findings should the nurse identify as indicative of ventricular tachycardia?
A. Presence of U waves
B. ST segment elevation greater than 1 mm
C. PR interval greater than 0.20 seconds
D. QRS complexes wider than 0.15 seconds
Answer: D
Rationale: Ventricular tachycardia originates from the ventricles, causing a wide QRS complex (typically
>0.12 seconds, and often >0.15 seconds) due to abnormal ventricular depolarization. The other options
are associated with different conditions: prolonged PR interval indicates first-degree AV block, U waves
may suggest hypokalemia, and ST elevation is seen in myocardial infarction.
13. A nurse in an emergency department is assessing a client with major depressive disorder.
Which of the following actions should the nurse take first? (Click on the exhibit tabs for additional
information about the client. There are three tabs that contain separate categories of data.) Vital
Signs: Temperature 37.3°C (99.1°F), Pulse 90/min, Respiratory rate 18/min, BP 140/90 mm Hg
A. Initiate suicide precautions.
B. Administer an antidepressant medication.
C. Obtain a blood glucose level.
D. Apply oxygen via nasal cannula.
Answer: C
Rationale: The correct answer is to obtain a blood glucose level because the vital signs (elevated BP and
pulse) may indicate hypoglycemia or hyperglycemia, which can mimic or exacerbate depressive
symptoms. Checking glucose is a priority to rule out a medical cause before proceeding with psychiatric
interventions.
14. A nurse is assessing a client who has a serum magnesium level of 1.0 mEq/L. Which clinical
finding should the nurse anticipate?
A. Hyperactive deep tendon reflexes
B. Hypoactive deep tendon reflexes
C. Muscle weakness and flaccidity
D. Decreased respiratory rate
Answer: A
Rationale: A magnesium level of 1.0 mEq/L indicates hypomagnesemia (normal 1.3-2.1 mEq/L).
Hypomagnesemia causes neuromuscular irritability, leading to hyperactive reflexes, tremors, and
