A client diagnosed with DIC is ordered heparin. What is the reason for this medication?
- A. Prevent clot formation
- B. Increase clot formation
- C. Increased blood flow to target organs
- D. Decrease blood flow to target organs
Correct Answer: A
Rationale: Heparin is a medication commonly used to prevent clot formation in various clinical conditions, including Disseminated Intravascular Coagulation (DIC). DIC is a serious condition characterized by abnormal blood clotting and bleeding throughout the body. Heparin works by inhibiting the formation of new clots and preventing the existing clots from further growing, thus helping to manage and prevent complications associated with DIC. By using heparin, the aim is to help stabilize the patient's clotting process and reduce the risk of severe complications such as organ damage or failure.

A patient is hemorrhaging from multiple trauma sites. The nurse expects that compensatory mechanisms associated with hypovolemia would cause all of the following symptoms except:
- A. Hypertension
- B. Tachycardia
- C. Oliguria
- D. Tachypnea
Correct Answer: A
Rationale: In a patient experiencing hemorrhage from multiple trauma sites leading to hypovolemia, compensatory mechanisms typically include an increase in heart rate (tachycardia), a decrease in urine output (oliguria), and an increase in respiratory rate (tachypnea). These mechanisms are the body's way of trying to maintain vital organ perfusion in the setting of decreased blood volume. However, hypertension is not typically seen in the setting of hypovolemia. In fact, blood pressure tends to decrease as a result of reduced circulating volume.
The Foley Family is caring for their youngest child, Justin, who is suffering from tetralogy of Fallot. Which of the following are defects associated with this congenital heart condition?
- A. Aorta exits from the right ventricle, pulmonary artery exits from the left ventricle, and two noncommunicating circulations
- B. Ventricular septal defect, overriding aorta, pulmonic stenosis (PS), and right ventricular hypertrophy
- C. Coarctation of aorta, aortic valve stenosis, mitral valve stenosis, and patent ductus arteriosus
- D. Tricuspid valve atresia, atrial septal defect, ventricular septal defect, and hypoplastic right ventricle
Correct Answer: B
Rationale: Tetralogy of Fallot is a congenital heart condition characterized by four specific defects:
Which of the following is an early sign of anemia?
- A. Palpitations
- B. Pallor
- C. Glossitis
- D. Weight loss
Correct Answer: B
Rationale: Pallor, or paleness of the skin, is an early sign of anemia. Anemia occurs when there is a decrease in the number of red blood cells or the amount of hemoglobin in the blood, resulting in reduced oxygen supply to the body's tissues. This lack of oxygen can cause the skin to appear pale due to decreased blood flow. Other common symptoms of anemia may include fatigue, weakness, shortness of breath, dizziness, and cold hands and feet. Palpitations, glossitis, and weight loss are not typically early signs of anemia.
The nurse is caring for a client in the emergency room diagnosed with Bell's palsy. The client has been taking acetaminophen (Tylenol), and acetaminophen overdose is suspected. The nurse anticipates that the antidote to be prescribed is:
- A. Pentostatin (Nipent)
- B. Fludarabine (Fludara)
- C. Auranofin (Ridaura)
- D. Acetylcysteine Mucomyst)
Correct Answer: D
Rationale: Acetylcysteine (Mucomyst) is the antidote for acetaminophen (Tylenol) overdose. If an overdose of acetaminincophen is suspected, acetylcysteine should be administered within 8-10 hours of ingestion to prevent liver damage and failure. Pentostatin, Fludarabine, and Auranofin are not antidotes for acetaminophen overdose and are used for other medical conditions.
The single parent of a 3-year-old child who has just been diagnosed with chickenpox tells the nurse that she cannot afford to stay home with the child and miss work. The parent asks the nurse if some medication will shorten the course of the illness. Which is the most appropriate nursing intervention?
- A. Reassure the parent that it is not necessary to stay home with the child.
- B. Explain that no medication will shorten the course of the illness.
- C. Explain the advantages of the medication acyclovir (Zovirax) to treat chickenpox.
- D. Explain the advantages of the medication VCZ immune globulin (VariZIG) to treat chickenpox.
Correct Answer: B
Rationale: The most appropriate nursing intervention in this scenario is to explain to the parent that no medication will shorten the course of chickenpox. Chickenpox is a viral illness caused by the varicella-zoster virus, and there is no specific treatment to shorten its duration. Antiviral medications like acyclovir are typically reserved for severe cases or for individuals with compromised immune systems. VCZ immune globulin (VariZIG) is used for post-exposure prophylaxis in susceptible individuals who have been exposed to chickenpox and are at high risk for severe disease.
