A)The client punctures the fingertip.
B)The client puts on gloves.
C)The client smears the blood on the reagent strip.
D)The client washes the hands.

Accepted Answer

Washing hands is an important step to ensure cleanliness and accuracy in blood glucose monitoring.

Question 2

What should the nurse instruct a client for obtaining a clean voided urine specimen?
A)Collect at least 5 mL of urine.
B)Collect the first voided specimen in the morning.
C)Keep the specimen on ice.
D)Void in a sterile cup.

Accepted Answer

Collecting the first voided specimen in the morning is the best choice as it is the most concentrated urine and provides the most accurate results. Other instructions for obtaining a clean voided urine specimen may include properly cleaning the genital area, collecting mid-stream urine, and avoiding contamination from toilet paper or menstrual blood.

Question 3

A client asks the nurse,"Why do I have to monitor my blood glucose levels?" What is an appropriate response from the nurse?
A)"Because your doctor ordered it."
B)"If I were you,I would monitor the blood glucose when I didn't feel good."
C)"Monitoring your blood glucose better enables you to manage your diabetes."
D)"You can eat anything you want."

Accepted Answer

Monitoring blood glucose levels is essential for managing diabetes. By monitoring blood glucose levels, the client can better understand how their body is responding to food, medication, and activity. This information helps the client to make informed decisions about how to manage their diabetes, which can ultimately improve their health outcomes. Choices A, B, and D are not appropriate responses as they do not provide a clear explanation of why monitoring blood glucose levels is important.

Question 4

The nurse is teaching a client with heart failure about diagnostic tests.Which test should the nurse emphasize in this teaching?
A)BNP
B)CBC
C)LDH
D)PKU

Accepted Answer

BNP (brain natriuretic peptide) is a diagnostic test commonly used in heart failure to detect the presence and severity of heart failure. It is a key indicator of heart function and can help guide treatment decisions. The other options (CBC, LDH, PKU) are not commonly used in the diagnosis or monitoring of heart failure.

Question 5

A)"I need to hyperextend my neck."
B)"I need to say 'ah.'"
C)"I will need to sit up."
D)"The nurse will use a light."

Accepted Answer

Hyperextending the neck is not necessary for a throat culture and may indicate that the client did not understand the proper procedure for the test. The other options are all accurate statements about the test.

Question 6

A)Always accompany the client to collect a specimen.
B)Handle the specimen discreetly.
C)Clean technique should be used with all specimen collection.

Question 7

A client is scheduled for a barium enema.What is the nursing priority for this client?
A)Assess bowel sounds.
B)Assess for allergies.
C)Cleanse the bowel.
D)Keep the client NPO.

Accepted Answer

The nursing priority for a client scheduled for a barium enema is to cleanse the bowel. This is essential to provide clear imaging during the procedure. Therefore, the nurse should assist the client in following the bowel preparation regimen and ensure that it is completed prior to the procedure. Assessing bowel sounds and allergies may also be important, but they are not the priority for this procedure. Keeping the client NPO is also not necessary for a barium enema.

Question 8

The nurse is collecting a sputum specimen from a client.Which action should the nurse take during the collection of this specimen?
A)Collect at least 30 mL of sputum.
B)Offer mouth care.
C)Take shallow breaths.

Offering mouth care before collecting a sputum specimen helps to reduce contamination of the specimen with oral bacteria.

Question 9

The nurse is assisting a client with a diagnostic test.Which role should the nurse expect to perform in the intratest phase?
A)Assess the data.
B)Collect the specimen.
C)Observe the client.
D)Prepare the client.

Accepted Answer

In the intratest phase, the nurse's role typically involves collecting the specimen and ensuring proper handling and labeling, as this phase focuses on the actual performance of the diagnostic test.

Question 10

A client is to have an echocardiogram.Which statement by the client indicates the teaching about the test has been effective?
A)"I'm told this test causes no discomfort."
B)"I will have to walk on a treadmill."
C)"I will need to remain NPO."
D)"I will need to take my pulse prior to the test."

Accepted Answer

Choice A is the correct answer because an echocardiogram is a noninvasive test that causes no discomfort to the patient. Choice B is incorrect because a treadmill test is an exercise stress test, not an echocardiogram. Choice C is incorrect because the patient does not need to be NPO for an echocardiogram. Choice D is incorrect because while the patient's pulse may be monitored during the test, they do not need to take their pulse ahead of time.

Question 11

The nurse needs to obtain a sputum specimen from a client.What should the nurse have the client do?
A)Apply sterile gloves.
B)Clear the throat.
C)Cough to bring up secretions.
D)Rinse the mouth with mouthwash prior to the collection.

Accepted Answer

The client should be instructed to cough to bring up secretions from the lungs, which would be collected as a sputum specimen.

Question 12

The nurse is reviewing laboratory results for a client.Which diagnostic study determines how well blood glucose levels have been controlled in the client?
A)Blood chemistry
B)Capillary blood glucose
C)Hemoglobin A1c
D)Serum electrolytes

Accepted Answer

Hemoglobin A1c provides an average of blood glucose levels over the previous three months, giving a better understanding of overall blood glucose control compared to a single blood glucose level or blood chemistry panel. Capillary blood glucose levels can provide immediate results but may not be as accurate as Hemoglobin A1c over an extended period. Blood chemistry and serum electrolytes provide different information unrelated to blood glucose levels.

Question 13

A client is prescribed a diagnostic test requiring a 24-hour stool specimen.What should this test indicate to the nurse?
A)Analyze the stool for dietary products and digestive secretions.
B)Detect the presence of bacteria or viruses.
C)Detect the presence of ova and parasites.
D)Determine the presence of occult blood.

A)A catheter will be inserted into the bladder.
B)A liver biopsy will be done.
C)An abdominal paracentesis will be done.
D)A thoracentesis will be done.

Accepted Answer

Abdominal paracentesis is the removal of ascites fluid from the abdominal cavity by inserting a needle through the abdominal wall. It is important for the nurse to educate the client about the procedure and what to expect, as well as monitoring for any complications such as infection, bleeding or perforation of organs. Options A, B, and D are not relevant to this procedure.

Question 17

A client is having a lumbar puncture.In which position should the nurse place the client?
A)Lateral with head bent toward the chest and knees flexed onto the abdomen
B)Lying prone,with the knees drawn up toward the abdomen
C)Sitting bent over from the waist with legs extended
D)Supine with knees pulled toward the chest

Accepted Answer

The lateral position with the head bent toward the chest and knees flexed onto the abdomen helps to open up the spaces between the vertebrae, making it easier to access the lumbar region for the procedure.

A)Defecate in the toilet.
B)Follow sterile technique.
