Accepted Answer

The answer of An obese patient is suspected of having...

Question 2

A nurse is assessing a patient who will be undergoing magnetic resonance imaging of the pancreas with a gadolinium-based contrast agent (GBCA).Given the use of this contrast medium, the nurse should especially evaluate the patient for which of the following?

Accepted Answer

Gadolinium-based contrast agents (GBCAs) are associated with a risk of developing nephrogenic systemic fibrosis (NSF) in patients with renal dysfunction. Therefore, the nurse should evaluate the patient's renal function and assess for any signs of NSF after the administration of GBCA. Pancreatitis, cirrhosis, and cardiac disease are not directly related to the use of GBCA for MRI of the pancreas.

Question 3

A nurse is assisting with a lung ventilation scan, which requires administration of a contrast medium.The nurse should prepare the patient for which type of administration of this medium?

Accepted Answer

In a lung ventilation scan, the patient inhales a radioactive gas to assess airflow in the lungs.

Question 4

A nurse is giving an overview of the lung perfusion scan to a patient who is preparing to undergo it.The nurse should explain that after an intravenous radionuclide is administered to the patient, the abdomen is scanned using which of the following?

Accepted Answer

The gamma camera is used to scan the abdomen after an intravenous radionuclide is administered to the patient for the lung perfusion scan. Magnetic resonance imaging, computed tomography, and X-rays are not typically used for this type of scan.

Question 5

A nurse is preparing a lactose solution in 250 mL of room temperature water to administer to a patient in a lactose tolerance test.The patient weighs 20 kg.What is the dose of lactose that the nurse should add to the glass of water?

Accepted Answer

The answer of A nurse is preparing a lactose solution...

Question 6

A nurse is reviewing the laboratory results of a female patient's luteinizing hormone (LH)test.In interpreting the results of this test, the nurse should keep in mind that LH level varies in accordance with the menstrual cycle and menopausal status of a woman, with the highest levels occurring during which of the following phases?

Accepted Answer

LH levels peak during the ovulatory phase of the menstrual cycle, which occurs around day 14 in a normal 28-day cycle. During this phase, the pituitary gland releases a surge of LH, which triggers ovulation. LH levels are low during the early follicular phase and rise gradually as ovulation approaches. In the luteal phase, LH levels decrease again. In postmenopausal women, LH levels are generally elevated due to decreased estrogen feedback.

Question 7

A patient is preparing to undergo lymphangiography.This test is often used to assist in the diagnosis of which of the following?

Accepted Answer

Lymphangiography is a medical imaging technique used to diagnose lymphatic system disorders, including Hodgkin's disease. It involves injecting a contrast dye into the lymphatic vessels to identify any blockages or abnormalities.

Question 8

A patient is suspected of having hemolytic anemia due to an enzyme deficiency.Which test should the nurse expect the health-care provider to order for this patient to assess this problem?

Accepted Answer

Pyruvate kinase (PK) is an enzyme that plays a critical role in the production of ATP by red blood cells. Deficiency of this enzyme can lead to hemolytic anemia. Therefore, PK assay is the appropriate test to assess hemolysis related to enzyme deficiency. Prolactin and PSA levels are unrelated to this condition, and pseudocholinesterase testing is more commonly used to assess the metabolism of certain medications.

Question 9

A mother brings her 13-year-old daughter into the office for her first gynecological examination.The mother tells the nurse that she has heard of a vaccination available for girls her daughter's age that can help prevent cervical cancer.The nurse recommends a vaccine for which of the following?

Accepted Answer

The human papillomavirus (HPV) vaccine is recommended for girls and boys around the age of 11-12 to help prevent HPV-related cancers and genital warts. It is most effective when given before the individual becomes sexually active. It is not recommended for preventing herpes, HIV, or hepatitis B.

Question 10

A patient has unexplained abdominal pain and gastrointestinal (GI)bleeding.The health-care provider suspects ectopic gastric mucosa.The nurse should prepare the patient for which of the following diagnostic tests?

Accepted Answer

Meckel's diverticulum scan is a diagnostic test used to detect ectopic gastric mucosa, which is a common finding in Meckel's diverticulum. Meckel's diverticulum is a small outpouching of the intestine that results from incomplete closure of the omphalomesenteric duct during embryonic development. It can contain tissue from the stomach or pancreas that secretes acid, leading to abdominal pain and GI bleeding. Mediastinoscopy is a procedure used to examine the mediastinum, while a myocardial infarct scan is used to detect damage to the heart muscle. Abdominal magnetic resonance imaging (MRI) is a non-invasive diagnostic test that uses magnetic fields and radio waves to create images of the abdomen. While MRI can be used for a range of diagnostic purposes, it is not the best choice for detecting ectopic gastric mucosa specifically.

Question 11

A patient's laboratory test results indicate elevation of lactose dehydrogenase isoenzyme 5 (LDH₅).This finding is most consistent with which of the following?

Accepted Answer

LDH5 is primarily found in the liver and skeletal muscle. Its elevation is most consistent with liver-related conditions such as cirrhosis.

Question 12

A patient's laboratory test results indicate strongly positive findings for blood glucose and ketones in the urine.When assessing this patient, the nurse should look for which of the following signs, consistent with these findings?

Accepted Answer

The presence of ketones in the urine and high blood glucose levels are indicative of diabetic ketoacidosis, which can lead to the development of fruity-smelling breath due to the presence of ketones in the breath. Hyperactivity, sweating, and agitation are not specific signs of diabetic ketoacidosis.

Question 13

A patient's laboratory test results indicate an increased level of metanephrines.This finding is most indicative of which of the following?

Accepted Answer

An increased level of metanephrines is most indicative of a pheochromocytoma, a tumor that produces excess levels of catecholamines such as adrenaline and noradrenaline. Lymphoma, retinoblastoma, and glioma do not typically affect catecholamine levels.

Question 14

An older patient has suffered several bone fractures in the past year.The health-care provider is concerned that the patient may have a common degenerative bone disease that results in the bones becoming thinner and more brittle.Which of the following tests should the nurse most expect to be ordered for this patient?

Accepted Answer

Osteocalcin is a blood test that measures the amount of a specific protein that is produced by bone cells. It is used to assess bone formation and turnover, and can help diagnose conditions such as osteoporosis. Osmotic fragility, oxalate, and osmolality are not relevant tests for assessing bone health.

Question 15

A patient is dehydrated and needs to have his fluid and electrolyte balance assessed.Which of the following tests would be most appropriate for this purpose?

Accepted Answer

Osmolality is the measurement of concentration of particles in a solution, such as electrolytes, glucose, and urea, which affect fluid balance in the body. It is a more accurate indicator of hydration status than just measuring fluid intake or output. Osmotic fragility is a test to assess the fragility of red blood cells, osteocalcin is a marker of bone metabolism, and oxalate is a test to assess the level of oxalate, which can lead to kidney stone formation but is not directly related to fluid and electrolyte balance.

Question 16

A patient will be undergoing surgery with the use of succinylcholine as an anesthetic agent.Which test should the nurse expect the health-care provider to order to rule out increased risk for anesthesia-induced apnea due to a congenital deficiency?

Accepted Answer

Pseudocholinesterase testing can identify individuals with a congenital deficiency, which increases the risk of prolonged apnea after administration of succinylcholine. Prolactin testing and PSA testing are not relevant for this situation. PK testing is used to diagnose certain types of anemia, but is not relevant in assessing risk for anesthesia-induced apnea.

Question 17

A nurse is assisting with a gynecological laparoscopic examination.Which of the following findings would be most critical and would require immediate notification of the requesting health-care provider?

Accepted Answer

An ectopic pregnancy is a medical emergency that requires immediate intervention. It is a potentially life-threatening condition and must be reported to the requesting health-care provider right away. Endometriosis, ovarian cysts, and pelvic inflammatory disease may require medical intervention but are not considered emergency conditions.

Question 18

A patient is preparing to undergo cardiac positron emission tomography (PET).Given the site of this scan, which of the following extra steps should the nurse anticipate?

Accepted Answer

Cardiac PET scans typically require the patient to drink a solution containing glucose before the injection of a radionuclide, which allows for better imaging of the heart. Therefore, the nurse should anticipate this extra step and prepare the patient accordingly. Option B is not likely since anaphylactic responses are rare with PET scans. Option C may be necessary in some cases, but it is not a standard step for all patients undergoing cardiac PET. Option D may be necessary for some types of scans, but it is not specific to cardiac PET scans.

Question 19

A patient who gave birth 24 hours ago has not been able to breastfeed because her milk has not come in.Which test should the nurse expect the health-care provider to order for this patient to assess this problem?

Accepted Answer

Prolactin is a hormone responsible for milk production in lactating women. A blood test for prolactin levels can help determine if there is an issue with milk production. The other test options, PSA, pseudocholinesterase, and pyruvate kinase, are not relevant to lactation or breast milk production.

Question 20

A patient is suspected of having thrombocytopenia.Which test would be appropriate for confirming this suspicion?

Accepted Answer

Platelet antibodies are used to confirm the presence of thrombocytopenia, which is a condition characterized by low platelet count in the blood. Plasminogen, phosphorus, and porphyrins are not typically used as diagnostic tests for thrombocytopenia.
