the client appears restless and reports difficulty breathing. Upon auscultation
of the client's lungs, the nurse notes bilateral basilar crackles. Which actions
will the nurse take FIRST?
Place the client on 2 L of oxygen by nasal cannula and auscultate the
lungs.
Decrease the IV flow rate and administer furosemide as prescribed.
Stop the IV infusion and notify the health care provider.
Elevate the head of the bed and stop the IV infusion.
2. A nurse is preparing to suction a patient with a tracheostomy who shows
signs of respiratory distress. What should the nurse do first?
Call the physician for further orders.
Hyperoxygenate the patient before suctioning.
Immediately suction the tracheostomy.
Administer bronchodilators before suctioning.
3. In a scenario where a client in restraints becomes increasingly agitated, what
should the nurse prioritize to ensure effective care?
Notify the physician immediately without assessing the client.
Leave the client alone to calm down.
Increase the frequency of checks on the restraints.
Reassess the client's condition and consider alternatives to
restraints.
,4. With GERD, Proton Pump Inhibitors (PPI) are prescribed to:
Inhibit gastric acid formation
Potentiate the transport of hydrogen ions
Increase gastric acid secretion
Form a protective barrier on the gastric mucosa
5. The client has epilepsy and receives phenytoin (Dilantin). The client has been
seizure free and asks the nurse why he still needs blood tests when he is not
having seizures. What is the nurse's best response?
"This medication can cause a severe skin reaction called Steven-
Johnson syndrome if doses are too high."
"Dilantin tends to lower blood levels of potassium."
"Dilantin can cause blood thinning in some people."
"There is a narrow range between a helpful dose of this medication
and a dose that could make you feel sicker."
6. A patient with chronic bronchitis is at risk for developing pneumonia due to:
Overactive cilia in the lungs.
Mucus plugs.
Hypoxemia.
Inability to cough.
7. Why is it important for the nurse to recognize increased resistance during a
catheter insertion?
Increased resistance suggests the catheter is the wrong size.
, Increased resistance means the procedure should be stopped
immediately.
Increased resistance is normal and should be ignored.
Increased resistance may indicate an obstruction or complication
that requires assessment.
8. Why is monitoring creatinine levels essential in patients with acute kidney
injury?
Creatinine levels help determine the need for dialysis.
Creatinine levels are used to monitor blood pressure changes.
Creatinine levels reflect hydration status in the body.
Creatinine levels indicate kidney function and help assess the
severity of the injury.
9. In a patient with bronchial inflammation due to irritants, what nursing
intervention would be most appropriate to alleviate symptoms?
Administer bronchodilators as prescribed.
Provide high doses of corticosteroids immediately.
Limit the patient's fluid intake to reduce coughing.
Encourage the patient to smoke to clear the airways.
10. When resistance is met while inserting a urinary catheter, the patient is asked
to bear down. This is done to:
Stimulate a parasympathetic response that will slow the heart rate of
a patient going through a stressful procedure.
Stimulate a parasympathetic response that will stimulate contractions
of the detrusor muscles.
, Encourage the patient to void in hopes to negate the indication of
catheterization.
Relax the external sphincter muscle.
11. If a nurse observes a new rhythm in a client with diastolic heart failure, what
assessment should the nurse perform first to ensure patient safety?
Notify the physician without assessing the client.
Administer prescribed medications immediately.
Assess the client's vital signs and hemodynamic status.
Document the new rhythm in the client's chart.
12. What is one action a nurse should take when caring for a patient with a
gastrostomy tube?
Rotate the gastrostomy tube 360 degrees once daily
Only check the tube if there are signs of leakage
Administer medications through the tube without checking placement
Leave the tube in a fixed position
13. Describe how metoclopramide functions in the context of chemotherapy
treatment.
Metoclopramide increases the absorption of cisplatin in the body.
Metoclopramide works by blocking dopamine receptors in the
brain, which helps to reduce nausea and vomiting associated with
chemotherapy.
Metoclopramide enhances the immune response to chemotherapy.
Metoclopramide acts as a pain reliever during chemotherapy.
