Nursing Elites

1. Why is it often necessary to draw a complete blood count and differential (CBC/differential) when a client is being treated with an antiepileptic drug (AED)?

• A. The hematocrit is adversely affected due to increased vascular volume.
• B. AEDs can lead to blood dyscrasia as a side effect.
• C. AEDs may cause aplastic anemia and megaloblastic anemia.
• D. Some AEDs induce white blood cell reduction.

Correct answer: B

Rationale: When a client is being treated with antiepileptic drugs (AEDs), it is essential to monitor for potential side effects on blood parameters. Some AEDs can lead to blood dyscrasia, which includes conditions like aplastic anemia and megaloblastic anemia. Therefore, drawing a complete blood count and differential helps in identifying these adverse effects early. Choices A, C, and D are incorrect because the primary concern when monitoring blood parameters in clients on AEDs is the risk of blood dyscrasia, not changes in hematocrit due to vascular volume, white blood cell reduction, or immune modulation.

2. What is the best lab test to diagnose disseminated intravascular coagulation (DIC)?

• A. platelet count
• B. prothrombin time (PT)
• C. partial thromboplastin time (PTT)
• D. D-dimer

Correct answer: D

Rationale: The best lab test to diagnose disseminated intravascular coagulation (DIC) is the D-dimer test. In DIC, numerous small clots form throughout the body and are rapidly broken down. D-dimer measures a specific fibrin split product and is the most specific test for DIC. Platelet count (Choice A) is decreased in DIC due to consumption, but it is not specific for diagnosing DIC. Prothrombin time (PT - Choice B) and partial thromboplastin time (PTT - Choice C) are both elevated in DIC because clotting factors have been used up, but they are not specific for DIC as they can be elevated in other conditions as well.

3. Which of the following diseases or conditions is least likely to be associated with an increased potential for bleeding?

• A. metastatic liver cancer
• B. gram-negative septicemia
• C. pernicious anemia
• D. iron-deficiency anemia

Correct answer: C

Rationale: Pernicious anemia is least likely to be associated with an increased potential for bleeding. Pernicious anemia results from vitamin B12 deficiency due to a lack of intrinsic factor, leading to faulty absorption from the gastrointestinal tract. While pernicious anemia can lead to other health issues, bleeding tendencies are not a primary concern. Metastatic liver cancer (choice A) can cause liver dysfunction leading to decreased synthesis of clotting factors, increasing the risk of bleeding. Gram-negative septicemia (choice B) can lead to disseminated intravascular coagulation (DIC) causing excessive bleeding. Iron-deficiency anemia (choice D) can result in microcytic hypochromic red blood cells, which can impair oxygen transport and lead to tissue hypoxia, but it is not directly associated with a significant potential for bleeding.

4. A patient who has delivered an 8.2 lb. baby boy 3 days ago via c-section, reports white patches on her breast that aren't going away. Which of the following medications may be necessary?

• A. Nystatin
• B. Atropine
• C. Amoxil
• D. Lortab

Correct answer: A

Rationale: The patient is likely experiencing thrush, a fungal infection, which can present as white patches on the breast that persist. Nystatin is an antifungal medication commonly used to treat thrush. Therefore, the correct answer is Nystatin. Atropine is not indicated for this condition and is used for different purposes. Amoxil is an antibiotic and would not be effective against a fungal infection like thrush. Lortab is a pain medication and is not appropriate for treating thrush.

5. The nurse is obtaining a health assessment from the preoperative client scheduled for hip replacement surgery. Which statement by the client would be most important for the nurse to report to the physician?

• A. "I had chickenpox when I was 8 years old."?
• B. "I had rheumatic fever when I was 10 years old."?
• C. "I have a strong family history of gastric cancer."?
• D. "I have pain in my hip with any movement."?

Correct answer: B

Rationale: The most important statement for the nurse to report to the physician is that the client had rheumatic fever when they were 10 years old. This information is crucial as individuals who have had rheumatic fever require pre-medication with antibiotics before any surgical or dental procedure to prevent bacterial endocarditis. Reporting this history ensures the client's safety during the hip replacement surgery. The other options, such as having chickenpox in the past, a family history of gastric cancer, or experiencing hip pain, are important for the client's overall health assessment but do not have the same immediate implications for the upcoming surgery as the history of rheumatic fever.
