1. A nurse is caring for a patient who has a chest tube connected to a
water-seal drainage system. The nurse notices that there is continuous
bubbling in the water-seal chamber. What should the nurse do next?
a) Clamp the chest tube and notify the physician.
b) Check the system for air leaks and tape any connections that are loose.
c) Document the finding and continue to monitor the patient.
d) Increase the suction pressure to remove the excess air.
*Answer: b) Check the system for air leaks and tape any connections that
are loose.*
Rationale: Continuous bubbling in the water-seal chamber indicates an air
leak in the system, which can compromise the drainage of fluid and air
from the pleural space and increase the risk of tension pneumothorax.
, The nurse should check the system for air leaks and tape any
connections that are loose. Clamping the chest tube can cause a
buildup of pressure in the pleural space and worsen the patient's
condition. Documenting the finding and continuing to monitor the
patient is not enough to address the problem. Increasing the suction
pressure will not stop the air leak and may cause damage to the lung
tissue.
2. A nurse is preparing to administer an intramuscular injection to a
patient who has a history of anaphylaxis. The nurse has drawn up 0.3
mL of epinephrine 1:1000 in a syringe. What is the most appropriate
site for the injection?
a) Deltoid muscle
b) Vastus lateralis muscle
c) Ventrogluteal muscle
d) Dorsogluteal muscle
*Answer: b) Vastus lateralis muscle*
Rationale: The vastus lateralis muscle is the preferred site for
intramuscular injections of epinephrine in patients who have a history
of anaphylaxis, because it has a large surface area, is easily accessible,
and has fewer major blood vessels and nerves than other sites. The
, deltoid muscle is not recommended because it has a smaller surface
area and may not absorb the medication as quickly. The ventrogluteal
and dorsogluteal muscles are not recommended because they are
located near major blood vessels and nerves and have a higher risk of
injury.
3. A nurse is performing a head-to-toe assessment on a patient who was
admitted with abdominal pain and vomiting. The nurse palpates the
patient's abdomen and finds that it is rigid, tender, and distended.
What should the nurse do next?
a) Auscultate the abdomen for bowel sounds.
b) Measure the patient's abdominal girth and document it.
c) Elevate the head of the bed to 30 degrees and apply a warm compress.
d) Notify the physician and prepare for emergency surgery.
*Answer: d) Notify the physician and prepare for emergency surgery.*
Rationale: A rigid, tender, and distended abdomen is a sign of acute
abdominal emergency, such as perforation, obstruction, or ischemia,
which requires immediate surgical intervention. The nurse should
notify the physician and prepare for emergency surgery. Auscultating
the abdomen for bowel sounds is not a priority at this time, as it will
not change the management of the patient. Measuring the patient's
