Q1. A nurse receives report on 4 patients. Which patient should be assessed first?
A) Patient with a broken hip requesting pain medication
B) Patient with a tracheostomy and oxygen saturation of 88%
C) Patient who needs discharge teaching about warfarin
D) Patient scheduled for an abdominal CT scan in 2 hours
☑ 100%Correct Answer: B
Rationale: Airway and breathing are always the priority. An SpO₂ of 88% indicates hypoxemia;
the tracheostomy patient is at high risk for airway obstruction or mucus plugging. Pain,
teaching, and diagnostic tests can wait.
Q2. An RN on a medical-surgical unit delegates a task to an LPN/LVN. Which task is
appropriate?
A) Initial assessment of a new admission with chest pain
B) Administration of IV push morphine to a post-op patient
C) Administering oral metoprolol to a stable hypertensive patient
D) Creating a care plan for a patient with diabetes
, 2
☑ 100%Correct Answer: C
Rationale: LPNs/LVNs can administer oral medications to stable patients. Initial assessments, IV
push opioids, and care plan creation require RN scope of practice.
Q3. A charge nurse is assigning staff. Which patient should be assigned to an experienced RN
rather than a new graduate?
A) Patient with pneumonia on room air
B) Patient with appendicitis scheduled for surgery in 4 hours
C) Patient with unstable atrial fibrillation and a new heparin drip
D) Patient with a urinary tract infection receiving oral antibiotics
☑ 100%Correct Answer: C
Rationale: Unstable dysrhythmia and a titratable IV anticoagulant drip require critical thinking
and experience. Stable patients can be managed by new graduates under supervision.
Q4. A patient with a chest tube has continuous bubbling in the water seal chamber. What
action should the nurse take first?
A) Clamp the chest tube near the insertion site
B) Assess for an air leak and notify the provider
C) Increase suction pressure
D) Document the finding as normal
, 3
☑ 100%Correct Answer: B
Rationale: Continuous bubbling in the water seal chamber indicates an air leak. Clamping could
cause tension pneumothorax. The nurse should assess the system and then notify the provider.
Q5. Which task can the nurse delegate to a nursing assistive personnel (NAP)?
A) Measuring a patient's blood pressure every 15 minutes after a procedure
B) Assessing a patient's chest pain severity
C) Teaching a patient how to use an incentive spirometer
D) Evaluating the effectiveness of pain medication
☑ 100%Correct Answer: A
Rationale: NAP can perform vital sign measurement. Assessment, teaching, and evaluation
require licensed nursing judgment.
Q6. A patient with heart failure suddenly develops crackles, dyspnea, and pink frothy sputum.
Which action should the nurse take first?
A) Administer IV morphine
B) Place the client in high-Fowler's position
C) Restrict oral fluids
D) Prepare the client for intubation
, 4
☑ 100%Correct Answer: B
Rationale: Positioning the client upright decreases venous return and improves lung expansion,
making it the priority intervention during acute pulmonary edema.
Q7. A client with diabetes mellitus becomes shaky and diaphoretic. The blood glucose level is
52 mg/dL. Which intervention is most appropriate?
A) Give regular insulin
B) Administer glucagon IM
C) Offer 15 g of rapid-acting carbohydrate
D) Start a dextrose-free IV infusion
☑ 100%Correct Answer: C
Rationale: Conscious clients experiencing hypoglycemia should receive 15 g of a rapid-acting
carbohydrate such as juice or glucose tablets.
Q8. Which electrolyte imbalance places a client at greatest risk for cardiac dysrhythmias?
A) Calcium 9.0 mg/dL
B) Magnesium 2.0 mEq/L
C) Potassium 2.8 mEq/L
D) Sodium 140 mEq/L
