Question 1

The nurse is reading a computer printout of the results of a cerebrospinal fluid (CSF) analysis performed on an adult client who has undergone lumbar puncture. Evaluation of the results by the nurse leads to the determination that which of the following CSF findings is abnormal?

Accepted Answer

Protein levels in the cerebrospinal fluid (CSF) are normally between 15 and 45 mg/dL. A protein level of 100 mg/dL is considered abnormal and may indicate a disease or injury to the central nervous system.

Question 2

The client with a history of seizure disorder is having a routine serum phenytoin level drawn. The nurse who receives a telephone report of the results notes that the client's blood level of the medication is within the therapeutic range if the value reported is which of the following?

Accepted Answer

The therapeutic range for serum phenytoin levels is typically between 10-20 mcg/mL. A level of 15 mcg/mL falls within this range.

Question 3

The client with chronic obstructive pulmonary disease (COPD) has had a sample for a serum theophylline level drawn as part of routine follow-up care. Which of the following results would lead the nurse to conclude that the client has most likely been compliant with medication therapy?

Accepted Answer

The therapeutic range for serum theophylline levels is typically between 10-20 mcg/mL. A level of 14 mcg/mL falls within this range, indicating likely compliance with medication therapy.

Question 4

A long-term care nurse about to give a daily dose of digoxin (Lanoxin) is told that a serum digoxin level drawn earlier in the day measured 2.7 ng/mL. The nurse should take which of the following actions first?

Accepted Answer

Question 5

The client is receiving oral anticoagulant therapy with warfarin (Coumadin). The result of a newly drawn prothrombin time (PT) is 40 seconds. The nurse anticipates carrying out a prescription to do which of the following?

Accepted Answer

A PT of 40 seconds is significantly higher than the normal range, indicating an increased risk of bleeding. The nurse should hold the next dose of warfarin to prevent further anticoagulation.

Question 6

The adult client has had serum electrolyte levels drawn. The nurse receiving the results by telephone from the laboratory would be most concerned with which of the following results?

Accepted Answer

A potassium level of 5.4 mEq/L is above the normal range (3.5-5.0 mEq/L) and indicates hyperkalemia, which can be dangerous and requires prompt attention.

Question 7

The client with heart disease is scheduled to receive a daily morning dose of furosemide (Lasix). The nurse would report which of the following serum potassium levels to the health care provider before administering the daily dose?

Accepted Answer

Furosemide (Lasix) is a loop diuretic that can cause significant potassium loss, leading to hypokalemia. A serum potassium level of 3.0 mEq/L is considered low (normal range is approximately 3.5 to 5.0 mEq/L), and administering furosemide could further lower this level, increasing the risk of cardiac arrhythmias and other complications. Therefore, it is important to report this value to the healthcare provider before administering the dose.

Question 8

The nurse is providing directions to a client about how to test a stool for occult blood. The nurse cautions that the presence of which of the following could cause a false -negative result?

Accepted Answer

Ascorbic acid (vitamin C) can cause a false-negative result in fecal occult blood tests because it has antioxidant properties that can prevent the chemical reaction needed for the test to detect blood.

Question 9

The nurse receives a telephone laboratory report indicating that a diabetic client has a glycosylated hemoglobin A_1c level of 7.6%. The nurse plans to provide diabetic teaching in which of the following priority areas?

Accepted Answer

Glycosylated hemoglobin (HbA1c) levels reflect the average blood glucose levels over the past 2 to 3 months. A level of 7.6% is above the generally recommended target for most patients with diabetes, indicating that the patient has experienced periods of hyperglycemia. Therefore, teaching measures to prevent hyperglycemia would be the priority to help bring their HbA1c level closer to the target range, typically less than 7% for most adults with diabetes.

Question 10

The nurse is assisting in monitoring a client who is receiving a transfusion of packed red blood cells (PRBCs). Before leaving the room, the nurse tells the client that it is most important to immediatelyreport which of the following symptoms of a transfusion reaction, if they occur? Select all that apply.

Accepted Answer

Chills, chest pain, low back pain, and difficulty breathing are symptoms of a transfusion reaction that should be reported immediately. These symptoms can indicate serious complications such as hemolytic reactions or allergic reactions.

Question 11
