Question

A nurse is caring for a client who has a new prescription for warfarin. The nurse should use the results of which of the following diagnostic tests to monitor the effect of this therapy?

Answer 1

Correct Answers:

Prothrombin time (PT)

Rationale :

🩸Warfarin inhibits vitamin K–dependent clotting factors affecting the extrinsic pathway, which is monitored by PT.

🕒PT measures the time for prothrombin to convert to thrombin, directly reflecting warfarin’s anticoagulant effect.

💊Platelet count assesses number of platelets but does not evaluate clotting factor activity.

✨Activated partial thromboplastin time (aPTT) evaluates the intrinsic pathway and is used to monitor heparin, not warfarin.

📌Core Message

Monitor warfarin therapy by measuring PT, as it reflects changes in vitamin K–dependent clotting factors.

Answer 2

Correct Answers:

Paralytic ileus

Rationale :

🚫An absence of bowel sounds and no flatus indicate a lack of intestinal motility.

🛑Abdominal distention occurs when gas accumulates due to paralysis of the bowel.

⏳On postoperative day three, paralytic ileus is common following anesthesia and abdominal manipulation.

🔍Neither infection nor fecal impaction typically presents with silent bowel sounds and no gas passage without other distinct signs.

📌Core Message

Postoperative paralytic ileus causes absent bowel sounds, distention, and no flatus due to transient GI inactivity.

Answer 3

Correct Answers:

Serum creatinine

Rationale :

🧪Serum creatinine reflects glomerular filtration rate and is a direct indicator of renal function.

🔍Elevated creatinine levels signal impaired kidney clearance, often seen in lupus nephritis.

🩸C-reactive protein and erythrocyte sedimentation rate measure inflammation but do not assess renal filtration.

🌡️Antinuclear antibody titers confirm SLE diagnosis but do not indicate organ function.

📌Core Message

Assess renal function in SLE by monitoring serum creatinine for filtration performance.

Answer 4

Correct Answers:

Ineffective airway clearance related to thick, copious secretions

Rationale :

🫁Radical neck dissection can compromise upper airway patency through edema and secretion buildup.

🩸Thick, copious secretions increase the risk of airway obstruction and respiratory distress.

⏳Maintaining a patent airway is the most immediate priority to prevent hypoxia.

🍽️Nutrition, infection risk, and communication needs are secondary until airway stability is ensured.

📌Core Message

Ensure a patent airway immediately after neck dissection to prevent respiratory compromise.

Answer 5

Correct Answers:

Allow the client to keep her hearing aids in.

Rationale :

👂Hearing aids improve communication and comprehension of preoperative instructions.

📝Keeping auditory devices until just before anesthesia ensures informed consent and reduces anxiety.

⚗️Vitamins and tongue jewelry pose ingestion or aspiration risks and are withheld.

🥤Clear liquids have a time cutoff, but sensory aids like hearing aids are prioritized for safety.

📌Core Message

Maintain hearing aid use preoperatively to support effective communication.

Answer 6

Correct Answers:

Serum potassium

Rationale :

💧Furosemide increases urinary excretion of electrolytes, notably potassium.

⚡Hypokalemia can precipitate dangerous cardiac arrhythmias in heart failure.

🔬Monitoring serum potassium helps detect and correct electrolyte imbalances early.

🍟Triglycerides, cholesterol, and amylase are not directly affected by loop diuretics.

📌Core Message

Monitor serum potassium during furosemide therapy to prevent hypokalemia-related complications.

Answer 7

Correct Answers:

Hypotension

Rationale :

💔Shock causes decreased cardiac output and perfusion, leading to hypotension.

🩸The body compensates with tachycardia, not bradycardia, to maintain perfusion.

🚽Urine output decreases as renal perfusion drops, not increases.

🍽️Bowel sounds become hypoactive or absent due to reduced GI perfusion, not hyperactive.

📌Core Message

Hypovolemic shock presents with hypotension due to insufficient circulating volume.

Answer 8

Correct Answers:

Urinary tract infection

Rationale :

🦠A urinary tract infection produces cloudy, foul-smelling urine from bacterial activity.

🌡️Dark amber color reflects concentrated urine, often seen with inflammation.

⚗️Retention or frequency alter volume and timing but don’t inherently change clarity or odor.

🚫Incontinence refers to leakage, not changes in urine appearance or smell.

📌Core Message

Dark, cloudy, malodorous urine is characteristic of a urinary tract infection.

Answer 9

Correct Answers:

Low BP and high pulse rate

Rationale :

💧Hypovolemia reduces circulating volume, leading to low blood pressure.

❤️Compensatory tachycardia occurs to maintain cardiac output.

🩸Sympathetic activation in shock increases heart rate, not decreases.

🔍High blood pressure or bradycardia contradicts typical hypovolemic shock physiology.

📌Core Message

Hypovolemic shock features low BP and high pulse rate as compensatory mechanisms.

Answer 10

Correct Answers:

WBC count 20,000/mm3

Rationale :

🩸A WBC count of 20,000/mm³ suggests a significant infection or inflammatory response.

🔍Preoperative infection increases surgical risks and often warrants delaying arthroplasty.

🧪Normal creatinine, potassium, and hematocrit values indicate no immediate concern for renal, electrolyte, or oxygen-carrying capacity.

⚕️Prioritizing abnormal findings that can alter operative outcomes ensures patient safety.

📌Core Message

Elevated WBC preoperatively must be managed to reduce infection risk and improve outcomes.
