Acyclovir (Zovirax) is given to children with chickenpox to:
- A. minimize scarring.
- B. decrease the number of lesions.
- C. prevent aplastic anemia.
- D. prevent spread of the disease.
Correct Answer: B
Rationale: Acyclovir (Zovirax) is an antiviral medication commonly used to treat infections caused by the herpes virus, including chickenpox. When given to children with chickenpox, acyclovir helps decrease the number of lesions present on the skin by slowing down the replication of the virus. This not only helps alleviate the discomfort associated with the rash but also reduces the risk of potential complications and accelerates the healing process. While acyclovir does not completely eliminate the virus from the body, it can help control the symptoms and prevent severe manifestations.

A patient returns from surgery ff. a TURP with a three-way Foley catheter and continuous bladder irrigation. Postoperative orders include Meperidine (Demerol) 75 mg IM q3h as needed for pain, belladonna and opium (B&O) suppository q4h as needed, and strict I&O. the patient complains of painful bladder spasms, and the nurse observes blood-tinged urine on the sheets. Which action should the nurse take?
- A. Give Demerol
- B. Give B&O suppository
- C. Warm the irrigation solution to body temperature
- D. Notify the physician stat
Correct Answer: D
Rationale: The nurse should notify the physician stat in this situation. The presence of blood-tinged urine and painful bladder spasms in a patient with a three-way Foley catheter and continuous bladder irrigation post TURP could indicate a potential complication such as hemorrhage or clot retention. It is crucial to ensure prompt medical evaluation and intervention to address these issues effectively. Waiting or administering pain medication without further assessment could delay necessary treatment and lead to worsening of the patient's condition. Therefore, notifying the physician immediately is the most appropriate action in this scenario.
Which of the following is the most common cause of hyperaldosteronism?
- A. Excessive sodium intake
- B. Deficient potassium intake
- C. A pituitary adenoma
- D. An adrenal adenoma
Correct Answer: D
Rationale: The most common cause of hyperaldosteronism is an adrenal adenoma, which is a benign tumor of the adrenal gland. Adrenal adenomas produce excessive amounts of aldosterone, a hormone that regulates sodium and potassium balance in the body. This overproduction of aldosterone can lead to increased sodium retention and potassium excretion, resulting in hypertension and low potassium levels in the blood. Excessive sodium intake and deficient potassium intake are not common causes of hyperaldosteronism. Pituitary adenomas are associated with conditions such as Cushing's syndrome or acromegaly, but not hyperaldosteronism.
Which is most important in the immediate care of the newborn?
- A. Maintain patent airway.
- B. Maintain stable body temperature.
- C. Administer prophylactic eye care.
- D. Establish identification of mother and baby.
Correct Answer: A
Rationale: Maintaining a patent airway is the most critical aspect in the immediate care of a newborn. An open airway is essential for the newborn to breathe effectively and receive adequate oxygen. Any obstruction in the airway can lead to respiratory distress and compromise the baby's oxygenation. Therefore, ensuring the airway is clear and the newborn can breathe properly is the top priority in providing immediate care. While other choices are important aspects of newborn care, ensuring a patent airway takes precedence in order to support the newborn's respiratory function and overall well-being.
A client diagnosed with hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is stabilized and prepared for discharge. When preparing the client for discharge and home management, which of the following statements indicates that the client understands her condition and how to control it?
- A. “I can avoid getting sick by not becoming dehydrated and by paying attention to my need to urinate, drink, or eat more than usual.â€
- B. "If I experience trembling, weakness, and headache, I should drink a glass of soda that contains sugar."
- C. "I will have to monitor my blood glucose level closely and notify the physician if it's constantly elevated."
- D. "If I begin to feel especially hungry and thirsty, I'll eat a snack high in carbohydrates."
Correct Answer: A
Rationale: Option A demonstrates the client's understanding of her condition and how to control it. Hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is characterized by high blood glucose levels and dehydration. To control the condition, it is crucial to prevent dehydration by staying well-hydrated and paying attention to cues such as increased thirst and urination. By being mindful of these signs and symptoms, the client can take proactive measures to maintain adequate hydration levels and prevent HHNS complications. This statement reflects a clear understanding of the importance of hydration in managing the condition. Options B, C, and D do not address the specific needs of a client with HHNS and may potentially lead to incorrect management of the condition.
Assume you are evaluating the specificity of the indirect fluorescence antibody test for rapid diagnosis of Campylobacter enteritis. The number of normal persons tested is 150 and the test is positive in 30 persons. The specificity of this test is
- A. 20%
- B. 40%
- C. 60%
- D. 80%
Correct Answer: D
Rationale: Specificity = (True negatives / Total normals) * 100 = [(150 - 30) / 150] * 100 = 80%.
