GUARANTEED SUCCESS
GRADED A+
1. A nurse is caring for a client who has a prescription for furosemide. Which of the following
laboratory values should the nurse monitor?
A. Calcium
B. Sodium
C. Potassium
D. Hemoglobin
Correct Answer: C. Potassium
Rationale: Furosemide, a loop diuretic, causes increased excretion of potassium. Monitoring
potassium is essential to avoid hypokalemia, which can lead to cardiac arrhythmias.
2. A client with pneumonia is receiving oxygen at 4 L/min via nasal cannula. Which finding
should the nurse report to the provider?
A. Respiratory rate of 20/min
B. SaO₂ of 88%
C. Clear breath sounds
D. Temperature of 37.8°C (100°F)
Correct Answer: B. SaO₂ of 88%
,Rationale: An oxygen saturation of 88% indicates hypoxemia and requires prompt
intervention. The goal is typically above 92
A client is prescribed metformin for type 2 diabetes. Which of the following instructions should
the nurse include?
A. Take with food to reduce gastrointestinal upset
B. Increase intake of alcohol to avoid hypoglycemia
C. Discontinue if experiencing muscle pain
D. Limit fluid intake during treatment
Correct Answer: A. Take with food to reduce gastrointestinal upset
Rationale: Metformin can cause GI side effects; taking it with food minimizes nausea and
diarrhea.
A nurse is caring for a client post-appendectomy. Which intervention is a priority?
A. Encourage coughing and deep breathing exercises
B. Limit oral fluid intake
C. Restrict activity to bedrest
D. Avoid early ambulation
Correct Answer: A. Encourage coughing and deep breathing exercises
Rationale: These prevent atelectasis and pneumonia after surgery.
Which of the following electrolyte imbalances is most commonly caused by vomiting?
A. Hyperkalemia
B. Hypokalemia
C. Hypernatremia
D. Hyponatremia
Correct Answer: B. Hypokalemia
Rationale: Vomiting leads to loss of gastric acid and potassium, causing hypokalemia.
A client with congestive heart failure is prescribed a low-sodium diet. Which food choice
indicates understanding?
,A. Canned soup
B. Fresh fruit
C. Frozen dinner
D. Processed cheese
Correct Answer: B. Fresh fruit
Rationale: Fresh fruit is naturally low in sodium, unlike canned or processed foods.
A nurse assesses a client who reports shortness of breath and chest pain. Which action should
the nurse take first?
A. Administer oxygen
B. Obtain vital signs
C. Notify the healthcare provider
D. Perform a 12-lead ECG
Correct Answer: A. Administer oxygen
Rationale: Oxygen is priority to improve tissue perfusion in chest pain with respiratory distress.
Which nursing action best prevents catheter-associated urinary tract infections (CAUTI)?
A. Use sterile technique during catheter insertion
B. Change catheter every 3 days
C. Clamp catheter tubing at night
D. Encourage fluid restriction
Correct Answer: A. Use sterile technique during catheter insertion
Rationale: Sterile technique prevents introduction of pathogens into the urinary tract.
A client on morphine reports constipation. Which intervention is appropriate?
A. Increase fluid and fiber intake
B. Recommend bedrest
C. Suggest taking morphine with food
D. Advise to reduce fluid intake
Correct Answer: A. Increase fluid and fiber intake
, Rationale: Fluids and fiber help prevent opioid-induced constipation.
Which vital sign change indicates a possible opioid overdose?
A. Increased respiratory rate
B. Bradycardia
C. Hypertension
D. Tachycardia
Correct Answer: B. Bradycardia
Rationale: Opioids depress the CNS, causing slowed breathing and heart rate.
A nurse is teaching a client about self-administering insulin. Which statement indicates correct
understanding?
A. Rotate injection sites to prevent lipodystrophy
B. Inject insulin into a muscle
C. Store insulin at room temperature for 6 months
D. Inject insulin immediately after meals
Correct Answer: A. Rotate injection sites to prevent lipodystrophy
Rationale: Rotating sites prevents tissue damage and absorption issues.
A client is prescribed enoxaparin after surgery. Which lab test should the nurse monitor?
A. Platelet count
B. Prothrombin time (PT)
C. Activated partial thromboplastin time (aPTT)
D. International normalized ratio (INR)
Correct Answer: A. Platelet count
Rationale: Enoxaparin can cause thrombocytopenia; monitoring platelet count prevents
complications.
Which of the following symptoms is most indicative of hypoxia?
A. Bradycardia
B. Cyanosis
