Question 1
Which of the following lab tests would indicate liver function
impairment?
A) Elevated creatinine level
B) Elevated ALT and AST levels
C) Increased white blood cell count
D) Low potassium level
Answer: B) Elevated ALT and AST levels
Rationale: Elevated levels of alanine aminotransferase (ALT) and
aspartate aminotransferase (AST) are indicators of liver impairment. The
other tests are related to kidney function or indicate other conditions.
Question 2
What is the primary nursing intervention for a patient experiencing
chest pain?
A) Assess the pain characteristics and vital signs
B) Administer prescribed pain medication
C) Provide reassurance to the patient
D) Encourage deep breathing exercises
Answer: A) Assess the pain characteristics and vital signs
,Rationale: The primary intervention is to assess the patient's pain and
vital signs to determine the severity and possible cause of the chest pain
before any other interventions are carried out. This helps in making
informed decisions for further action.
Question 3
For a patient undergoing a diagnostic procedure involving contrast
dye, what is a critical nursing action prior to the procedure?
A) Checking the patient’s blood pressure
B) Assessing for allergies to iodine or shellfish
C) Ensuring the patient is NPO for 8 hours
D) Administering pain medication
Answer: B) Assessing for allergies to iodine or shellfish
Rationale: Assessing for allergies to iodine or shellfish is critical to
prevent an allergic reaction to the contrast dye. While other actions may
be important, allergy assessment is the priority.
Question 4
What is the most common side effect of long-term corticosteroid
use?
A) Increased energy levels
B) Hypoglycemia
C) Osteoporosis
D) Dehydration
Answer: C) Osteoporosis
,Rationale: Long-term corticosteroid use can lead to osteoporosis due to
impaired calcium absorption and bone density reduction. Increased
energy levels and hypoglycemia are not typical effects, and while
dehydration can occur, it is less common than osteoporosis.
Question 5
In managing a patient with a nasogastric tube, what is the nurse’s
priority assessment?
A) Confirmation of tube placement
B) Measuring gastric residual volume
C) Checking tube patency
D) Assessing bowel sounds
Answer: A) Confirmation of tube placement
Rationale: Confirming the correct placement of the nasogastric tube is
the priority to prevent aspiration and ensure safe feeding. While the
other assessments are important, proper placement is critical before any
other actions.
Question 6
Which of the following is a proper technique for administering
subcutaneous injections?
A) Injecting at a 90-degree angle
B) Massaging the injection site after administration
C) Pinching the skin to create a fold
D) Using a large bore needle for ease of administration
Answer: C) Pinching the skin to create a fold
, Rationale: Pinching the skin creates a fold to ensure the medication is
delivered properly into the subcutaneous tissue. Subcutaneous injections
should be administered at a 45- to 90-degree angle, depending on the
patient's body composition, and the site should not be massaged unless
specified.
Question 7
What assessment finding in a patient with a history of cardiac
disease requires immediate attention?
A) Blood pressure of 130/80 mmHg
B) New onset of chest pain radiating to the left arm
C) Mild swelling in the ankles
D) Heart rate of 70 bpm
Answer: B) New onset of chest pain radiating to the left arm
Rationale: New onset of chest pain radiating to the left arm is a critical
sign that may indicate an acute myocardial infarction and requires
immediate medical attention. The other findings do not indicate an
urgent issue.
Question 8
In preparing a patient for discharge after a stroke, which of the
following is crucial for the nurse to include in the teaching plan?
A) The need for complete bed rest
B) Importance of participating in rehabilitation
C) Avoiding all physical activities
D) Managing stress through medication only
