Question 1

A patient who is scheduled for percutaneous transhepatic cholangiography (PTC)asks a nurse about the purpose of this examination.Which response by the nurse is correct?

Accepted Answer

Percutaneous transhepatic cholangiography (PTC) is a procedure used to examine the bile ducts of the liver. It involves using a special X-ray to insert a needle into the liver and inject a dye that shows the ducts that drain the gallbladder. The purpose of this procedure is to identify any obstructions or other abnormalities in the bile ducts. A biopsy of the liver, removal of the gallbladder through a small tube, or insertion of a tube through the throat and stomach to remove gallstones are not part of this procedure.

Question 2

A patient is suspected of having hemochromatosis.Which test would be most appropriate to confirm this suspicion?

Accepted Answer

Hemochromatosis is a genetic condition that leads to iron overload. Hemosiderin is a protein complex that stores iron in tissues and organs, and its presence can indicate excessive iron accumulation, confirming the diagnosis of hemochromatosis. The other options (A, B, and C) are not specific to hemochromatosis and are used to diagnose other conditions such as PNH, hemolytic anemia, and different types of hemoglobinopathies.

Question 3

A patient's laboratory test results indicate an elevated $\beta$2-microglobulin (BMG)blood level.Which of the following conditions would be most associated with this finding?

Accepted Answer

Elevated levels of beta-2 microglobulin (BMG) in the blood are commonly observed in patients with lymphoproliferative disorders, such as leukemia. Elevated BMG levels may also be seen in other malignancies, but leukemia is the most closely associated condition.

Question 4

A patient with persistent pleural edema is scheduled for a magnetic resonance imaging (MRI)of the chest.Which information in the patient's medical history should the nurse identify as a contraindication for this procedure?

Accepted Answer

An implanted cardiac pacemaker is a contraindication for an MRI due to the risk of interference with the pacemaker. Allergy to shellfish, knee replacement, and lower extremity tattoo are not contraindications for an MRI.

Question 5

Two hours after completing a computed tomography (CT)scan of the brain with contrast, an ambulatory patient asks a nurse for "medication for itching." What should be the nurse's first response?

Accepted Answer

The answer of Two hours after completing a computed tomography...

Question 6

An infant's laboratory test results reveal elevated bilirubin levels.The nurse should expect to see which of the following skin colorations associated with this condition?

Accepted Answer

Elevated bilirubin levels in infants can lead to a condition called jaundice, which typically results in yellow skin coloration.

Question 7

A health-care provider has recommended that a patient undergo testing to determine risk for blood clots and stroke.Which test would be most appropriate for this purpose?

Accepted Answer

Homocysteine and methylmalonic acid levels are commonly used to assess risk for blood clots and stroke. High levels of these substances can indicate an increased risk for cardiovascular disease. HVA and 5-HIAA are metabolites of dopamine and serotonin, respectively, and are not typically used for assessing cardiovascular risk. Hexosaminidase A and B are enzymes used in the diagnosis of Tay-Sachs disease and are not related to cardiovascular risk.

Question 8

A nurse is performing a template bleeding time test on a patient.A bleeding time greater than which of the following is a critical finding that should prompt the nurse to immediately notify the patient's health-care provider?

Accepted Answer

A bleeding time greater than 14 minutes is a critical finding that should prompt the nurse to immediately notify the patient's health-care provider. A normal bleeding time ranges from 2 to 9 minutes, while a bleeding time greater than 9 minutes indicates a mild defect in the platelet function. A bleeding time greater than 14 minutes indicates a severe defect in the platelet function, and the patient is at an increased risk of bleeding. Thus, prompt notification of the health-care provider is necessary in such cases.

Question 9

A patient has a spinal tap to obtain cerebrospinal fluid (CSF)to test for Alzheimer's disease (AD)markers.When planning care for this patient after the specimen is collected, a nurse's priority should be to:

Accepted Answer

After a spinal tap, it is important to maintain the patient flat in bed for 8 hours or per institutional protocol to avoid the risk of spinal headache. The other options are not the nurse's immediate priority at this time. Decision-making about long-term placement can be addressed at a later time, the patient's food intake can be resumed once the patient is able to sit up without risk of aspiration, and reassurance about treatment options can also be provided at a later time.

Question 10

A nurse is preparing a patient for collection of cerebrospinal fluid for Alzheimer's disease markers.How should the nurse position the patient for this procedure?

Accepted Answer

The patient should be positioned in a side-lying position with the knees pulled up to the chest and the chin tucked for collection of cerebrospinal fluid. This position helps to open up the spaces in the spinal column, allowing for easier access to the cerebrospinal fluid. It also helps to reduce the risk of complications, such as post-lumbar puncture headache.

Question 11

A patient is undergoing blood gas testing to assess oxygenation and acid-base balance.Which of the blood gas measurements provide the most information about ventilation and is referred to as the respiratory component of acid-base balance?

Accepted Answer

PCO2 is the respiratory component of acid-base balance, reflecting the partial pressure of carbon dioxide in the blood, which is directly influenced by ventilation.

Question 12

An antenatal patient, in the third trimester of her pregnancy, has an obstetric ultrasound for a biophysical profile (BPP)to assess fetal wellness.The nurse performing the procedure should:

Accepted Answer

A normal BPP score is 10, and it requires observing the fetus for at least 30 minutes to assess all parameters (fetal heart rate, fetal breathing movements, fetal movements, fetal tone, and amniotic fluid volume) adequately.

Question 13

A nurse is assisting with a liver biopsy.When should the nurse administer ordered prophylactic antibiotics?

Accepted Answer

Prophylactic antibiotics are typically administered 1 hour before an incision to ensure adequate tissue levels of the antibiotic at the time of surgery, reducing the risk of postoperative infection.

Question 14

Which clinical manifestations should a nurse anticipate when assessing a patient who has a bone mineral densitometry (DEXA)T-score of -2.75?

Accepted Answer

A DEXA T-score of -2.75 indicates osteoporosis, which can lead to kyphosis (curvature of the spine), a decrease in height, and back pain. Bowing of the legs, flat feet, and hammertoe are not typically associated with osteoporosis. Crepitus, morning stiffness, and Heberden's nodes are more commonly associated with osteoarthritis. Edema of lower extremities, joint pain, and poor balance are not specific to osteoporosis and can have various causes.

Question 15

A patient is suspected of having myasthenia gravis.Which of the following biopsy procedures should the nurse expect to be performed to assist in diagnosing this condition?

Accepted Answer

The answer of A patient is suspected of having myasthenia...

Question 16

Despite using lotion and drying hands thoroughly after washing, a nurse observes increasing irritation of both hands occurring the day after working.A blood specimen tests positive for latex allergy.What pertinent history should the nurse relate to this finding?

Accepted Answer

Latex allergy is often associated with cross-reactivity to certain foods, including bananas, kiwis, pineapples, and peaches. It is important for the nurse to identify this history as it may help to prevent future allergic reactions. The other options are not as relevant to a latex allergy.

Question 17

A nurse is assisting with a cervical biopsy.During the procedure, iodine solution is used to cleanse the cervix and distinguish normal from abnormal tissue.This intervention is known as which of the following?

Accepted Answer

Schiller's test is a cervical biopsy procedure where iodine solution is used to identify normal and abnormal tissue. A Pap smear is a screening test to detect cervical cancer, while a colposcopy and cone biopsy are diagnostic procedures following an abnormal Pap test or biopsy.

Question 18

A patient has an antimitochondrial antibody (AMA)titer that is more than 1:40 and an alkaline phosphatase (ALP)level of 225 units/L.Based on his information, the nurse should assess this patient for signs of:

Accepted Answer

An elevated AMA titer and ALP level are suggestive of primary biliary cholangitis (PBC), a chronic liver disease that can lead to eventual liver failure. Therefore, the nurse should assess the patient for signs of liver failure such as jaundice, ascites, and hepatic encephalopathy. Renal failure, scleroderma, and pregnancy are not directly related to an elevated AMA titer and ALP level.

Question 19

Which laboratory result should a nurse interpret as an indication that a patient with respiratory acidosis is responding to treatment?

Accepted Answer

Increased serum bicarbonate (HCO3-) concentration indicates that the body is compensating for respiratory acidosis by retaining bicarbonate to neutralize the excess acid, showing an effective response to treatment.

Question 20

A patient is preparing to undergo transabdominal chorionic villus biopsy.In which position should the nurse place this patient?

Accepted Answer

The supine position is typically used for transabdominal procedures, allowing easy access to the abdomen.
