, Question 1
A client with acute decompensated heart failure is prescribed IV furosemide.
Which assessment finding indicates the medication is achieving its therapeutic
effect?
A. Urine output of 50 mL/hr with decreased dyspnea
B. Serum potassium increase from 3.2 to 4.0 mEq/L
C. Weight loss of 0.5 kg in 24 hours
D. Bilateral crackles auscultated at lung bases
Correct Answer: A - Urine output of 50 mL/hr with decreased
dyspnea
RATIONALE
Furosemide is a loop diuretic that promotes diuresis, reducing preload
and pulmonary congestion; increased urine output with improved
dyspnea indicates therapeutic effect. Weight loss of 0.5 kg is minimal;
expected is 0.5-1 kg/day, but the key is symptom relief. Potassium
increase is not a direct effect; furosemide can cause hypokalemia.
Crackles indicate worsening failure.
Question 2
A client with chronic obstructive pulmonary disease (COPD) has an arterial
blood gas: pH 7.32, PaCO2 58 mm Hg, HCO3- 28 mEq/L. Which acid-base
imbalance is present?
A. Respiratory acidosis, uncompensated
B. Respiratory acidosis, partially compensated
C. Metabolic alkalosis, uncompensated
D. Respiratory alkalosis, partially compensated
Correct Answer: B - Respiratory acidosis, partially compensated
Page 2
, RATIONALE
Elevated PaCO2 indicates respiratory acidosis; elevated HCO3-
indicates renal compensation, but pH is still below normal, so it is
partially compensated. Uncompensated would have normal HCO3-.
Metabolic alkalosis would have elevated pH and HCO3-. Respiratory
alkalosis would have low PaCO2.
Question 3
A client is admitted with acute pancreatitis. Which intervention should the
nurse anticipate implementing first?
A. Administer IV opioids for pain
B. Insert a nasogastric tube for decompression
C. Initiate a clear liquid diet
D. Place the client in a supine position
Correct Answer: A - Administer IV opioids for pain
RATIONALE
Pain management is a priority in acute pancreatitis; IV opioids are
often used. NG decompression is not routine unless ileus or severe
vomiting. Clear liquids are contraindicated initially (NPO). Supine
position may worsen pain; fetal position often relieves it.
Question 4
A client with a new colostomy has a stoma that is dark purple and dry. Which
action should the nurse take?
A. Document the finding as normal
B. Notify the surgeon immediately
C. Apply a moist dressing to the stoma
D. Increase oral fluid intake
Correct Answer: B - Notify the surgeon immediately
Page 3
, RATIONALE
A dark purple, dry stoma indicates ischemia/necrosis, requiring
immediate surgical evaluation. Normal stoma is pink/red and moist.
Moist dressing is not applied to stoma. Increasing fluids does not
address ischemia.
Question 5
A client is receiving heparin infusion for deep vein thrombosis. The aPTT is 90
seconds (control 30). Which action should the nurse take?
A. Continue the infusion at the current rate
B. Stop the infusion and prepare to administer protamine sulfate
C. Decrease the infusion rate and recheck aPTT in 4 hours
D. Administer vitamin K
Correct Answer: A - Continue the infusion at the current rate
RATIONALE
Therapeutic aPTT for heparin is typically 1.5-2.5 times control (45-75
seconds); 90 seconds is slightly high but may be acceptable depending
on protocol. However, standard is to adjust if >2.5x control. In many
protocols, 90 is within range? Actually, 90/30=3, which is high. Wait,
need to check. Usually therapeutic aPTT is 1.5-2.5 times control, so
45-75. 90 is above, so should decrease rate. But options: A continue, B
stop and protamine, C decrease and recheck, D vitamin K. Correct is
C. Let's correct: aPTT 90 is elevated; heparin should be titrated down.
Protamine is for overdose/bleeding. Vitamin K is for warfarin. So
answer C.
Question 6
A client with type 1 diabetes is found unresponsive with a blood glucose of 40
mg/dL. Which action should the nurse implement first?
A. Administer glucagon IM
B. Give 15 g of oral glucose
C. Start an IV and administer 50% dextrose
