ANSWER KEY & RATIONALES
nb nb nb



1. B) Clear lung sounds and decreased edema.
nb nb nb nb nb nb



o Rationale: Furosemide is a loop diuretic used to reduce fluid volume overload in nb nb nb nb nb nb nb nb nb nb nb nb nb



heart failure. Clear lung sounds (resolving crackles) and decreased peripheral ed
nb nb nb nb nb nb nb nb nb nb



ema indicate successful diuresis. nb nb nb



2. C) Elevated serum ammonia.
nb nb nb



o Rationale: The liver metabolizes ammonia. In cirrhosis, the liver cannot clear am nb nb nb nb nb nb nb nb nb nb nb



monia, leading to accumulation, which crosses the blood- nb nb nb nb nb nb nb



brain barrier and causes hepatic encephalopathy. nb nb nb nb nb



3. A) Supine, flat.nb nb



o Rationale: The patient must remain flat (supine) for 4–6 hours post- nb nb nb nb nb nb nb nb nb nb



lumbar puncture to prevent a spinal headache caused by cerebrospinal fluid leak
nb nb nb nb nb nb nb nb nb nb nb



age from the puncture site. nb nb nb nb



4. B) Serum lipase.nb nb



o Rationale: Serum lipase is the most sensitive and specific indicator for acute pan nb nb nb nb nb nb nb nb nb nb nb nb



creatitis. It remains elevated longer than amylase. nb nb nb nb nb nb



5. B) Hypertension and bradycardia (Cushing’s Triad).
nb nb nb nb nb



o Rationale: Cushing’s Triad (hypertension, bradycardia, and irregular respirations) nb nb nb nb nb nb nb n



is a late sign of increased ICP indicating brainstem compression.
b nb nb nb nb nb nb nb nb nb



6. C) Bananas. nb



o Rationale: Bananas are high in potassium. In CKD, the kidneys cannot excrete p nb nb nb nb nb nb nb nb nb nb nb nb



otassium effectively, leading to hyperkalemia, which can cause fatal cardiac arrh
nb nb nb nb nb nb nb nb nb nb



ythmias.
7. B) Remove and replace the inner cannula.
nb nb nb nb nb nb



o Rationale: If the inner cannula is obstructed, the priority is to remove it (clearing t
nb nb nb nb nb nb nb nb nb nb nb nb nb nb



he airway) and replace it with a clean one. This immediately restores the patent
nb nb nb nb nb nb nb nb nb nb nb nb nb nb



airway.
8. C) Prominent U waves.
nb nb nb



o Rationale: Hypokalemia (low potassium) is characterized by flattened T- nb nb nb nb nb nb nb nb



waves and the presence of prominent U waves. Tall, peaked T- nb nb nb nb nb nb nb nb nb nb



waves indicate hyperkalemia. nb nb



9. B) 0.9% Normal Saline.
nb nb nb



o Rationale: In DKA, the patient is severely dehydrated due to osmotic diuresis. Iso nb nb nb nb nb nb nb nb nb nb nb nb

10. C) Turn the patient to the side.
nb nb nb nb nb nb



o Rationale: The priority is to maintain a patent airway and prevent aspiration. Turn nb nb nb nb nb nb nb nb nb nb nb nb



ing the patient to the side (lateral position) allows secretions to drain from the mo
nb nb nb nb nb nb nb nb nb nb nb nb nb nb



uth. Do not restrain or put anything in the mouth. nb nb nb nb nb nb nb nb nb
