Question 1

A patient being prepared for a gastrointestinal blood loss scan asks the nurse, "Will the radioactive dye hurt me?" Which of the following responses by the nurse is best?

Accepted Answer

Option B reassures the patient that there is no radioactivity hazard and explains that there are rarely any side effects from the dye. It is the most appropriate and accurate response to the patient's question. Option A is incorrect as it provides inaccurate information. Option C is incorrect as it falsely suggests that the patient will need to stay in a special radioactive room for three days, which is not true for this type of scan. Option D is incorrect as it does not answer the patient's question about the dye.

Question 2

The laboratory test results of a patient with AIDS indicate an increase in CD4 and CD8 T cells of 200 cells/mm³ after having received antiretroviral therapy (ART)for 1 year.The nurse should interpret these results as indicating which of the following?

Accepted Answer

An increase in CD4 and CD8 T cells by 200 cells/mm3 after 1 year of ART indicates a significant improvement in the patient's immune function. This suggests that the ART is highly effective, as it has been able to suppress viral replication and allow the immune system to recover. Choices A, B, and C are incorrect, as they suggest that the ART is not effective or only modestly effective, which is not supported by the increase in T cells.

Question 3

A patient's laboratory test results indicate elevated total cholesterol level.The health-care provider is concerned, however, that the level might be falsely elevated.Which of the following factors could explain such a finding?

Accepted Answer

The answer of A patient's laboratory test results indicate elevated...

Question 4

A nurse is assessing a patient for potential contraindications for an upcoming computed tomography (CT)scan of the pituitary.When the nurse learns that the patient has a pheochromocytoma, the nurse notifies the health-care provider of this finding and the CT scan is cancelled.Why is pheochromocytoma a contraindication for a CT scan?

Accepted Answer

Pheochromocytoma is a tumor that produces excess adrenaline and other hormones, leading to high blood pressure. The injection of iodinated contrast medium during a CT scan can further increase blood pressure, potentially causing a hypertensive crisis. It is important to cancel the CT scan in this situation to avoid exacerbating the patient's condition.

Question 5

When a nurse is collecting blood, which step is essential when collecting a specimen in a light-blue-top (citrate)tube?

Accepted Answer

The light-blue-top tube contains sodium citrate, which acts as an anticoagulant by binding calcium in the blood. It is essential to fill these tubes completely to maintain the proper blood-to-anticoagulant ratio, ensuring accurate coagulation tests.

Question 6

The nurse is providing care for a patient scheduled for a computer tomography of the brain.Which of the following instructions would the nurse provide?

Accepted Answer

The best choice is D because it is important for the patient to increase their fluid intake after drinking contrast to help eliminate it from their body. A is not relevant to a CT scan, B does not provide any instructions for the patient, and C may not be necessary depending on the patient's medical history and condition.

Question 7

A nurse caring for a patient undergoing a bronchoscopy would be most concerned by which of the following?

Accepted Answer

Rapid breathing and restlessness may indicate respiratory distress or hypoxia, which are concerning during a bronchoscopy.

Question 8

The nurse is providing care for a woman with breast cancer whose bone scan revealed widely metastatic disease.The patient appears pale and shaken as her health-care provider leaves her room.Which of the following actions should the nurse take?

Accepted Answer

The patient seems to be in emotional distress and needs support. Sitting with the patient and holding her hand shows compassion and empathy, and allows for the patient to express her emotions and feelings. The other interventions may have some merit, but they do not address the patient's immediate emotional needs.

Question 9

A neonate is suspected of having thrush.Which test would be most appropriate for helping diagnose this condition?

Accepted Answer

Thrush is a fungal infection caused by Candida albicans. Therefore, a throat culture specifically for fungal growth would be the most appropriate test to diagnose thrush.

Question 10

The nurse is participating in the care of a 32-year-old man who suffered anoxia.The family is trying to determine if life support should be removed.Which of the following diagnostic tests should the nurse anticipate?

Accepted Answer

An EEG is a test that measures electrical activity in the brain and can help determine if there is any brain function. This can assist in the decision-making process regarding life support. A CT scan or PET scan may also be helpful, but an EEG is the most specific test for evaluating brain function. Corneal reflex testing is not a diagnostic test for brain function, but rather an assessment of neurologic function.

Question 11

A patient with possible exposure to tuberculosis (TB)returns to a clinic 48 hours following an intradermal (Mantoux)test.How should the nurse determine the results of the Mantoux test?

Accepted Answer

The correct method of interpreting the Mantoux test is to palpate the site of injection and use a ruler to measure the largest diameter of induration (not erythema). Erythema (redness) alone is not an adequate measure of a positive or negative reaction. The size of the induration is then used to determine the result, with a reaction of ≥10 mm generally considered positive in a patient with no known risk factors for TB.

Question 12

The nurse is completing a telephone history and pre-procedural instructions for a patient anticipating a parathyroid scan.Which of the following would be included?

Accepted Answer

A consent form is typically required for procedures involving scans or imaging to ensure the patient understands and agrees to the procedure.

Question 13

The nurse receives a call from a patient who had a cystoscopy the day before.The patient reports consistent sharp pain in the lower back.Which of the following responses by the nurse is best?

Accepted Answer

Persistent sharp pain in the lower back after cystoscopy can be a sign of complications such as bleeding or infection. The patient should be advised to go to urgent care or an emergency room for further evaluation and treatment.

Question 14

A nurse is reviewing an electrocardiogram for a patient who reports sudden onset of chest pain that radiates down the left arm and feels "like something is sitting on my chest." The nurse identifies an ST elevation.Other diagnostic data confirm a diagnosis of acute myocardial infarction.Which procedure should the nurse anticipate to be ordered immediately for this patient?

Accepted Answer

Cardiac catheterization is the most immediate and appropriate procedure for a patient with a confirmed diagnosis of acute myocardial infarction with ST elevation. This procedure allows for visualization of the coronary arteries and potential intervention such as angioplasty or stent placement to restore blood flow to the affected area of the heart. The other options (cardiac scoring, exercise stress test, and Holter monitoring) are not appropriate for an acute myocardial infarction with ST elevation and may be used for other cardiac issues or as follow-up tests after treatment.

Question 15

A patient is suspected of having a urinary tract infection.Which test would be most appropriate for helping diagnose this condition?

Accepted Answer

A urine culture is the most appropriate test for diagnosing a urinary tract infection. Stool culture and throat culture are not relevant tests for UTI diagnosis. Throat culture may be useful for diagnosing strep throat, but not for UTI.

Question 16

A nurse is observing the results of a patient's clot retraction test.A normal finding in this test would be that an incubated blood clot would shrink to half its original size in how long?

Accepted Answer

A normal finding in a clot retraction test is that an incubated blood clot would shrink to half its original size in 60 minutes.

Question 17

The nurse is providing care for a patient undergoing sialography.Which of the following statements indicates the need for further instruction?

Accepted Answer

This statement is incorrect as sialography involves injecting the dye directly into the salivary glands, not swallowing it. The patient may need further instruction on the actual procedure of sialography.

Question 18

A patient is suspected of having an Escherichia coli infection.Which test would be most appropriate for helping diagnose this condition?

Accepted Answer

A stool culture is most appropriate for diagnosing an Escherichia coli infection, as E. coli is commonly found in the gastrointestinal tract and can cause infections that are detected in stool samples.

Question 19

The nurse is caring for a patient who is scheduled for magnetic resonance angiography (MRA)of the brain.Which of the following statements best describes this test?

Accepted Answer

Magnetic resonance angiography (MRA) uses a magnetic field and pulses of radio wave energy to provide pictures of blood vessels inside the body. This test provides images of blood flow in normal or abnormal vessels in your brain. Options A and D describe other imaging tests (MRI and electroencephalography) that are not specific to blood vessels, and option B describes the use of contrast, which may or may not be used depending on the specific type of MRA being performed.

Question 20

A child has a positive result for a tine test as part of routine screening for school.Which is an appropriate response by a nurse when the parents ask what it means to have a positive tine test?

Accepted Answer

A positive tine test only indicates exposure to tuberculosis and does not confirm active disease. It is important to confirm the response with another test and further evaluation.
