Q&A | WGU
1. A patient with heart failure is being discharged with a prescription for Furosemide. Which
instruction should the nurse prioritize during discharge teaching?
A. Take the medication immediately before going to bed.
B. Weigh yourself daily at the same time and report a gain of 3 lbs in a day.
C. Limit intake of potassium-rich foods like bananas.
D. Discontinue the medication if you experience frequent urination.
Answer: B
Rationale: Daily weights are the most sensitive indicator of fluid status changes in heart
failure patients. Reporting a rapid weight gain allows for early intervention before severe
pulmonary edema occurs. Patients should also be taught that frequent urination is an
expected effect of this loop diuretic.
2. Which clinical manifestation should the nurse expect to find in a patient diagnosed with
Cushing’s Syndrome?
A. Hyperpigmentation and hypotension
B. Weight loss and tremors
C. Truncal obesity and a ‘buffalo hump’
,D. Tachycardia and heat intolerance
Answer: C
Rationale: Cushing’s syndrome results from an excess of cortisol, leading to characteristic
fat redistribution. This includes truncal obesity, a fatty hump between the shoulders, and a
rounded ‘moon face’. Hyperpigmentation and hypotension are more characteristic of
Addison’s disease, the opposite endocrine disorder.
3. A patient is admitted with a suspected Myocardial Infarction (MI). Which laboratory result
is the most specific indicator of myocardial injury?
A. Creatine Kinase (CK-MB)
B. Troponin I
C. Myoglobin
D. C-Reactive Protein (CRP)
Answer: B
Rationale: Troponin I is highly specific to cardiac muscle and is the preferred biomarker
for diagnosing an MI. It begins to rise within a few hours of injury and can remain elevated
for up to two weeks. While CK-MB is also used, it is less specific than Troponin because it
can be found in skeletal muscle.
4. A nurse is caring for a patient with a chest tube. What should the nurse do if the chest tube
becomes accidentally disconnected from the drainage system?
A. Clamp the chest tube immediately with two padded clamps.
, B. Instruct the patient to cough and deep breathe.
C. Cover the insertion site with an occlusive dressing.
D. Submerge the end of the tube in 1 inch of sterile water.
Answer: D
Rationale: Submerging the tube in sterile water creates a temporary water seal and
prevents air from entering the pleural space. This is a priority action to prevent a tension
pneumothorax. The nurse should then prepare a new drainage system for connection while
monitoring the patient’s respiratory status.
5. Which acid-base imbalance is most likely to occur in a patient who has been vomiting for
24 hours?
A. Metabolic Alkalosis
B. Respiratory Acidosis
C. Metabolic Acidosis
D. Respiratory Alkalosis
Answer: A
Rationale: Vomiting leads to the loss of hydrochloric acid from the stomach, which results
in an increase in the body’s pH. This condition is known as metabolic alkalosis because the
loss of acid leaves a relative excess of bicarbonate. The nurse should monitor for associated
electrolyte imbalances like hypokalemia.
