Question 5

A patient is scheduled for a clonidine suppression test.For which clinical manifestations should the nurse assess this patient? Select all that apply.

Accepted Answer

The clonidine suppression test is used to diagnose pheochromocytoma, a tumor of the adrenal gland that can cause excessive production of catecholamines, leading to symptoms such as diaphoresis (excessive sweating), headache, hypertension (high blood pressure), and palpitations (abnormal heartbeats).

Question 6

A nurse is preparing a patient to undergo magnetic resonance imaging (MRI)of the pancreas.The nurse understands that T1-weighted MRI images are best for depicting which of the following? Select all that apply.

Accepted Answer

T1-weighted MRI images are particularly useful for visualizing the anatomy and structure of organs, including the pancreatic parenchyma, detecting fatty infiltration due to the high signal from fat, and identifying carcinomas, which often appear with higher signal intensity compared to surrounding tissues.

Question 7

A nurse is teaching a class on breast cancer awareness at a community center.The nurse should mention that breast magnetic resonance imaging (MRI)is especially effective for which of the following? Select all that apply.

Accepted Answer

Breast MRI is particularly effective for evaluating mammogram abnormalities, identifying early breast cancer in high-risk women, imaging dense breast tissue, and examining augmented breasts. It is not typically used for routine screening in place of mammography.

Question 8

When reviewing a report from a bone mineral densitometry (DEXA), a nurse notes that the result is a T-score of -1.75.Which instructions should the nurse plan for this 62-year-old patient? Select all that apply.

Accepted Answer

A T-score of -1.75 indicates osteopenia, which is a condition where bone mineral density is lower than normal peak BMD but not low enough to be classified as osteoporosis. To prevent further bone loss, the nurse should advise the patient to avoid smoking, limit alcohol consumption, and engage in regular weight-bearing exercises. These lifestyle changes can help maintain or improve bone density.

Question 9

A patient is preparing to undergo positron emission tomography (PET)of the brain.The nurse is aware that this procedure has the greatest clinical impact in patients with which of the following conditions? Select all that apply.

Accepted Answer

PET scans are particularly useful in epilepsy for identifying seizure foci, in dementia for assessing brain metabolism and function, and in Parkinson's disease for evaluating dopaminergic function.

Question 10

A patient has a serum potassium level of 2.4 mEq/L.For which clinical signs and symptoms should the nurse assess this patient? Select all that apply.

Accepted Answer

A serum potassium level of 2.4 mEq/L indicates hypokalemia. Clinical signs and symptoms of hypokalemia include bradycardia, irregular heart rhythm, muscle cramps, and a peaked T wave on EKG. Diarrhea and hunger are not typically associated with hypokalemia.

Question 11

The nurse recognizes which of the following advantages of bladder ultrasound? Select all that apply.

Accepted Answer

The answer of The nurse recognizes which of the following...

Question 12

A patient's laboratory test results indicate type I hyperlipoproteinemia.Which of the following are the characteristics associated with this finding? Select all that apply.

Accepted Answer

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

Question 13

A nurse is reviewing a patient's health history in anticipation of the patient undergoing abdominal laparoscopy.Which of the following conditions should the nurse view as contraindications to this procedure? Select all that apply.

Accepted Answer

The answer of A nurse is reviewing a patient's health...

Question 14

A pregnant patient learns that laboratory screening indicates that she is positive for the hepatitis C antibody.Which additional diagnostic tests should the nurse anticipate? Select all that apply.

Accepted Answer

Aminotransferase (ALT) and Aspartate aminotransferase (AST) levels are liver enzymes that are typically elevated in patients with liver damage, such as that caused by hepatitis C infection. Hepatitis B serology is also relevant because co-infection with hepatitis B can occur and has implications for management and prognosis.

Question 15

The nurse is caring for a patient who recently underwent a thallium stress test.Which of the following instructions should be provided? Select all that apply.

Accepted Answer

The answer of The nurse is caring for a patient...

Question 16

The student nurse is reviewing lab results for a patient on a medical-surgical floor who has an elevated LDH (lactate dehydrogenase)level.The student learns LDH may be elevated in which of the following conditions? Select all that apply.

Accepted Answer

LDH (lactate dehydrogenase) is an enzyme found in almost all body tissues, but levels can rise in response to cell damage. Elevated LDH levels can indicate a variety of conditions including cirrhosis (A), congestive heart failure (B), leukemia (C), myocardial infarction (D), and hepatitis (E). These conditions involve tissue damage or increased cell turnover, which can lead to higher amounts of LDH in the blood. Myopia (F), a condition related to eye structure and not indicative of tissue damage or disease, would not cause elevated LDH levels.

Question 17

The nurse is being asked to participate in a random drug-screening program.Which of the following would the nurse expect to experience? Select all that apply.

Accepted Answer

In a random drug-screening program, a nurse would typically expect to provide a blood specimen and a urine sample. The process often includes the witnessed transfer of specimens in a sealed transport device and signed documentation to ensure the chain of custody and integrity of the samples. Pat-down body searches and stool samples are not standard procedures in drug screening.

Question 18

The nurse caring for a patient who underwent a cardiac catheterization recognizes that teaching has been effective if the patient chooses which of the following menu items? Select all that apply.

Accepted Answer

After a cardiac catheterization procedure, it is important for the patient to follow a heart-healthy diet that is low in fat, cholesterol, and sodium. Carrot and celery sticks, skim milk, and steamed cauliflower are all low in fat and cholesterol, and can be good choices for the patient. Au gratin potatoes, cream of mushroom soup, and bratwurst are high in fat and/or sodium and should be avoided.

Question 19

A patient's laboratory test results indicate a positive finding for lupus anticoagulant (LA)antibodies.The health-care provider suspects antiphospholipid antibody syndrome in this patient.In addition to this laboratory finding, one of which of the following clinical criteria must be met to confirm this suspected diagnosis? Select all that apply.

Accepted Answer

Antiphospholipid antibody syndrome is characterized by the presence of antiphospholipid antibodies in the context of clinical criteria such as vascular thrombosis and pregnancy morbidity, including recurrent miscarriages. Hypertension, high BMI, and gestational diabetes are not part of the diagnostic criteria for this condition.

Question 20

The nurse is caring for a woman who is undergoing positron emission tomography of the abdomen.Which of the following statements indicates pre-procedural teaching has been successful? Select all that apply.

Accepted Answer

The patient should remove jewelry to avoid interference with imaging (C). Remaining still is crucial for accurate PET scan images (D). Avoiding caffeine and alcohol helps ensure accurate results (E).
