A client with a 10-year history of emphysema is hospitalized for acute respiratory
distress. Which assessment finding would the nurse expect to identify?
1) Chest pain on inspiration
2) Prolonged expiration with use of accessory muscles
3) Signs and symptoms of respiratory alkalosis
4) Decreased respiratory rate

A child being treated with cardiac medications developed vomiting, bradycardia,
anorexia, and dysrhythmias. The nurse understands which medication toxicity is
responsible for these symptoms?
Digoxin
Nesiritide
Dobutamine
Spironolactone
Give this one a try later!
Digoxin
Rationale:
Digoxin helps improve pumping efficacy of the heart, but an overdose can
cause toxicity leading to nausea, vomiting, bradycardia, anorexia, and
dysrhythmias.
The nurse determined a client's arterial blood gases reflected a compensated
respiratory acidosis. The pH was 7.34; which additional laboratory value did the nurse
consider?
1) The partial pressure of oxygen (PO2) value is 80 mm Hg.
2) The partial pressure of carbon dioxide (PCO2) value is 60 mm Hg.
3) The bicarbonate (HCO3) value is 50 mEq/L (50 mmol/L).
4) Serum potassium value is 4 mEq/L (4 mmol/L).

During the oliguric phase of acute kidney injury, for which abnormal finding would the
nurse monitor in the client?
1. Hypothermia
2. Hyperphosphatemia
3. Hypocalcemia
4. Hypernatremia
Give this one a try later!
Hyperphosphatemia
Rationale:
The kidneys retain potassium during the oliguric phase of acute kidney
injury; an elevated potassium level is one of the main indicators for placing
a client on hemodialysis when he or she is experiencing acute kidney injury.
Hypothermia does not occur with acute kidney injury. Serum levels of
phosphorus decrease during the oliguric phase of kidney failure. The
retained fluids create a hemodilution effect and hyponatremia occurs, not
hypernatremia.
The nurse is assessing four different clients. Which findings show that the client is at
risk for heart disease?
Client 1: Red color assessed. Location assessed- face, area of trauma, sacrum,
shoulders
Client 2: Bluish color assessed. Location assessed- nail beds, lips, mouth, skin.
Client 3: Pallor color assessed. Location assessed- Face, conjunctiva, nail beds, palms
of hands.
, Client 4: Yellow orange color assessed. Location assessed- sclera, mucous
membranes, skin.
Give this one a try later!
Client 2
Rationale:
Client 2 is at risk for heart disease because the nail beds, lips, mouth, and
skin show cyanosis, or a bluish color. This may be due to an increased
amount of deoxygenated hemoglobin, which may be due to heart or lung
disease.
Which catecholamine receptor is responsible for increased heart rate?
Beta-1 receptor
Beta-2 receptor
Alpha-1 receptor
Alpha-2 receptor
Give this one a try later!
Beta-1 Receptor
Rationale:
Beta-1 receptors are responsible for increased heart rate. Beta-2 receptors,
alpha-1 receptors, and alpha-2 receptors are not present in the heart;
therefore, they are not responsible for increasing the heart rate. Beta
receptors are present in such organs as blood vessels, kidneys,
bronchioles, and bladder. Alpha receptors are present in such organs as
eyes, skin, and liver.
