Professional Nursing III / PN3 Exam Q&A |
Rasmussen University
1. A patient with a history of heart failure presents with a BNP level of 900 pg/mL. Which
assessment finding is most consistent with this lab value?
A. Increased urinary output
B. Generalized weakness
C. Bilateral crackles in the lungs
D. Flattened neck veins
Answer: C
Rationale: BNP is a hormone secreted by cardiomyocytes in the heart ventricles in
response to stretching caused by increased ventricular blood volume. A level of 900 pg/mL
indicates significant heart failure and fluid overload. Bilateral crackles suggest pulmonary
edema resulting from left-sided heart failure.
2. During a mass casualty incident, a nurse triages a victim who is unconscious, has a
respiratory rate of 6 breaths per minute, and a weak pulse. What color tag should be
assigned?
A. Green
B. Yellow
,C. Red
D. Black
Answer: C
Rationale: Red tags are assigned to patients with life-threatening injuries who have a
chance of survival if treated immediately. This patient has respiratory distress and altered
consciousness but is still alive. Black tags are reserved for those who are dead or whose
injuries are so severe they are not expected to survive even with care.
3. Which task is most appropriate for the RN to delegate to an Unlicensed Assistive Personnel
(UAP)?
A. Checking the blood pressure of a patient receiving a blood transfusion
B. Assisting a stable patient with ambulation for the first time post-op
C. Performing a sterile dressing change on a central line
D. Feeding a patient who was recently diagnosed with dysphagia
Answer: A
Rationale: Vital signs on a stable patient or as part of a routine procedure can be delegated
to UAPs. The RN remains responsible for the overall assessment of the patient during the
transfusion. Sterile procedures and patients with new-onset swallowing difficulties require
the advanced skill of a licensed nurse.
, 4. A patient is admitted with Acute Respiratory Distress Syndrome (ARDS) and placed on a
ventilator with high PEEP. What is the primary risk associated with high PEEP settings?
A. Respiratory alkalosis
B. Increased cardiac output
C. Pneumothorax due to barotrauma
D. Hypervolemia
Answer: C
Rationale: Positive End-Expiratory Pressure (PEEP) keeps alveoli open but increases
intrathoracic pressure. This can lead to barotrauma, resulting in a pneumothorax or
tension pneumothorax. It also typically decreases cardiac output by reducing venous
return to the heart.
5. A patient with cirrhosis develops hepatic encephalopathy. The nurse expects to administer
lactulose to achieve which goal?
A. Promote the excretion of ammonia in the stool
B. Increase serum protein levels
C. Decrease serum potassium levels
D. Reduce portal vein hypertension
Answer: A
