1. A nurse is assessing a client who has hypovolemic shock. Which
finding should the nurse expect?
A. Bounding pulse
B. Bradycardia
C. Cool, clammy skin
D. Increased urine output
Answer: C. Cool, clammy skin
Rationale: Hypovolemia decreases circulating volume and tissue
perfusion, causing compensatory vasoconstriction and cool, clammy
skin.
2. A nurse is caring for a client who has heart failure. Which finding
indicates worsening left-sided heart failure?
A. Peripheral edema
B. Crackles in the lungs
C. Jugular venous distention
D. Hepatomegaly
Answer: B. Crackles in the lungs
,Rationale: Left-sided heart failure causes pulmonary congestion,
which can produce crackles, dyspnea, and pulmonary edema.
3. A client taking warfarin should report which finding immediately?
A. Mild headache
B. Increased appetite
C. Black, tarry stools
D. Occasional fatigue
Answer: C. Black, tarry stools
Rationale: Black, tarry stools can indicate gastrointestinal bleeding,
an important complication of anticoagulant therapy.
4. A nurse is preparing to administer digoxin. Which finding requires the
nurse to withhold the medication and notify the provider?
A. Apical pulse of 54/min
B. Blood pressure 128/74 mm Hg
C. Respiratory rate 18/min
D. Potassium 4.2 mEq/L
Answer: A. Apical pulse of 54/min
Rationale: Digoxin can cause bradycardia. The medication is generally
withheld when the adult apical pulse is below 60/min and the
provider is notified.
5. Which finding is expected in a client experiencing diabetic
ketoacidosis (DKA)?
A. Bradycardia
B. Kussmaul respirations
,C. Hypoglycemia
D. Metabolic alkalosis
Answer: B. Kussmaul respirations
Rationale: DKA causes metabolic acidosis, and deep, rapid Kussmaul
respirations are a compensatory response to eliminate carbon dioxide.
6. A nurse is caring for a client who has COPD. Which oxygen
prescription should the nurse question?
A. Oxygen at 1 L/min via nasal cannula
B. Oxygen at 2 L/min via nasal cannula
C. Oxygen at 10 L/min via nonrebreather mask
D. Oxygen titrated to the prescribed saturation goal
Answer: C. Oxygen at 10 L/min via nonrebreather mask
Rationale: Clients with chronic CO₂ retention require carefully titrated
oxygen therapy. Excessive oxygen administration can worsen
hypercapnia in some clients.
7. A nurse is caring for a client after thyroidectomy. Which finding
requires immediate intervention?
A. Mild incisional pain
B. Hoarse voice
C. Stridor
D. Sore throat
Answer: C. Stridor
Rationale: Stridor can indicate airway obstruction from edema or
bleeding and requires immediate intervention.
, 8. A client with SIADH is most likely to have which laboratory finding?
A. Serum sodium 122 mEq/L
B. Serum sodium 148 mEq/L
C. Serum osmolality increased
D. Urine output increased
Answer: A. Serum sodium 122 mEq/L
Rationale: SIADH causes excessive water retention, resulting in
dilutional hyponatremia and concentrated urine.
9. Which assessment finding is most concerning in a client who has a
potassium level of 2.7 mEq/L?
A. Muscle weakness
B. Cardiac dysrhythmia
C. Increased appetite
D. Facial flushing
Answer: B. Cardiac dysrhythmia
Rationale: Severe hypokalemia can cause life-threatening cardiac
dysrhythmias and requires prompt treatment.
10. A nurse is teaching a client who has a new prescription for lisinopril.
Which adverse effect should the client report immediately?
A. Dry cough
B. Mild fatigue
C. Facial swelling
D. Increased urination
Answer: C. Facial swelling
