1. 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.

2. Signs of impaired breathing in infants and children include all of the following except:

• A. nasal flaring
• B. grunting
• C. seesaw breathing
• D. quivering lips

Correct answer: D

Rationale: Signs of impaired breathing in infants and children can manifest in various ways. Nasal flaring, grunting, and seesaw breathing are all indicative of respiratory distress in pediatric patients. Nasal flaring is the widening of the nostrils with breathing effort, grunting is a sound made during exhalation to try to keep the airways open, and seesaw breathing involves the chest moving in the opposite direction of the abdomen. However, quivering lips are not typically associated with impaired breathing in this context. Lip quivering is a distracter and not a common sign of respiratory distress in infants and children. Therefore, the correct answer is 'quivering lips.'

3. A client is experiencing chest pain. Which statement made by the client indicates angina rather than a myocardial infarction?

• A. "I became dizzy when I stood up."?
• B. "I was nauseated and began vomiting."?
• C. "The pain started in my chest and stopped after I sat down."?
• D. "The pain began with a migraine and progressed to numbness in my left arm."?

Correct answer: B

Rationale: The correct answer is: '"The pain started in my chest and stopped after I sat down."? This statement suggests angina rather than a myocardial infarction because angina is typically triggered by exertion or stress and relieved by rest. Nausea and vomiting (Choice B) are more commonly associated with a myocardial infarction. Choices A and D are not typical symptoms of either angina or myocardial infarction.

4. Erythropoietin used to treat anemia in clients with renal failure should be given in conjunction with:

• A. iron, folic acid, and B12.
• B. an increase in protein in the diet.
• C. vitamins A and C.
• D. an increase in calcium in the diet.

Correct answer: A

Rationale: Erythropoietin is necessary for red blood cell (RBC) production, and in clients with renal failure who lack endogenous erythropoietin, exogenous erythropoietin is administered. However, for erythropoietin to effectively stimulate RBC production, adequate levels of iron, folic acid, and vitamin B12 are crucial. These nutrients are essential for RBC synthesis and maturation. Therefore, the correct answer is to give iron, folic acid, and B12 with erythropoietin. Choice B, an increase in protein in the diet, is not necessary for RBC production and may exacerbate uremia in clients with renal failure. Choices C and D, vitamins A and C, and an increase in calcium in the diet, respectively, are not directly related to RBC production and are not required to enhance the effectiveness of erythropoietin.

5. A child with newly diagnosed leukemia is receiving chemotherapy. Which would be included in his plan of care by the nurse?

• A. Place the child in a negative pressure isolation room
• B. Administer prophylactic IV antibiotics
• C. Avoid high protein food intake
• D. Teach family and visitors handwashing techniques

Correct answer: D

Rationale: The correct answer is to teach family and visitors handwashing techniques. Any client on chemotherapy should have good infection control measures in place, such as handwashing by all who they encounter. Placing the child in a negative pressure isolation room (Choice A) is not necessary unless specifically indicated for a certain condition. Administering prophylactic IV antibiotics (Choice B) may not be part of the standard care plan for a child with leukemia receiving chemotherapy. Avoiding high protein food intake (Choice C) is not directly related to infection control and may not be necessary unless there are specific dietary restrictions.
