1. Why are subdural hemorrhages more common in the elderly?
- A. Increased anticoagulant use
- B. Increased risk of falls
- C. Brain atrophy
- D. Inconsistent care giving
Correct answer: C
Rationale: Subdural hemorrhages are more common in the elderly due to cerebral atrophy resulting from the natural aging process. This atrophy can lead to the stretching of bridging veins, making them more fragile and prone to tearing even with minor trauma. While increased anticoagulant use and a higher risk of falls are common in the elderly, brain atrophy plays a more direct role in the increased incidence of subdural hemorrhages. Inconsistent caregiving, on the other hand, is not a direct cause of subdural hemorrhages but may impact the overall management and outcome of such cases.
2. A child has just been diagnosed with juvenile idiopathic arthritis. Which of the following statements about the disease is most accurate?
- A. The child has a poor chance of recovery without joint deformity.
- B. Most children progress to adult rheumatoid arthritis.
- C. Nonsteroidal anti-inflammatory drugs are the first choice in treatment.
- D. Physical activity should be minimized.
Correct answer: C
Rationale: The correct answer is that nonsteroidal anti-inflammatory drugs are the first choice in treatment for juvenile idiopathic arthritis (formerly known as juvenile rheumatoid arthritis). NSAIDs are important as a first-line treatment and typically require 3-4 weeks for the therapeutic anti-inflammatory effects to be realized. Choice A is incorrect as early treatment can improve outcomes and prevent joint deformities. Choice B is incorrect as juvenile idiopathic arthritis does not necessarily progress to adult rheumatoid arthritis. Choice D is incorrect as physical activity should be encouraged in children with arthritis to maintain joint mobility and overall health.
3. The clinic nurse is obtaining data about a child with a diagnosis of lactose intolerance. Which data should the nurse expect to obtain on assessment?
- A. Reports of frothy stools and diarrhea
- B. Reports of foul-smelling ribbon stools
- C. Reports of profuse, watery diarrhea and vomiting
- D. Reports of diffuse abdominal pain unrelated to meals or activity
Correct answer: A
Rationale: Lactose intolerance commonly presents with frothy stools and diarrhea due to the inability to digest lactose. Other symptoms include abdominal distension, crampy abdominal pain, and excessive flatus. Foul-smelling ribbon stools are indicative of Hirschsprung's disease, not lactose intolerance. Profuse, watery diarrhea and vomiting are more characteristic of celiac disease. Diffuse abdominal pain unrelated to meals or activity is a typical symptom of irritable bowel syndrome, not lactose intolerance.
4. To prevent a Valsalva maneuver in a client recovering from an acute myocardial infarction, the nurse would:
- A. Assist the client in using the bedside commode
- B. Administer stool softeners daily as prescribed
- C. Administer antidysrhythmics PRN as prescribed
- D. Maintain the client on strict bed rest
Correct answer: B
Rationale: Administering stool softeners daily as prescribed is essential to prevent straining during defecation, which can lead to a Valsalva maneuver. Straining can increase intra-abdominal pressure, hinder venous return, and elevate blood pressure, risking cardiac complications in a client recovering from a heart attack. Using a bedside commode might be useful to minimize exertion during toileting but does not directly address the risk of a Valsalva maneuver. Administering antidysrhythmics PRN is not the primary intervention for preventing a Valsalva maneuver; these medications are used to manage dysrhythmias if they occur. Keeping the client on strict bed rest is not the best option as early mobilization is encouraged in post-myocardial infarction recovery to prevent complications such as deep vein thrombosis and muscle weakness.
5. A child weighing 30 kg arrives at the clinic with diffuse itching as the result of an allergic reaction to an insect bite. Diphenhydramine (Benadryl) 25 mg 3 times a day is prescribed. The correct pediatric dose is 5 mg/kg/day. Which of the following best describes the prescribed drug dose?
- A. It is the correct dose
- B. The dose is too low
- C. The dose is too high
- D. The dose should be increased or decreased, depending on the symptoms
Correct answer: B
Rationale: The correct pediatric dose of diphenhydramine is 5 mg/kg/day. This child weighs 30 kg, so the calculated dose would be 5 mg/kg x 30 kg = 150 mg/day. Since the prescription is for 25 mg 3 times a day, the total daily dose is 25 mg x 3 = 75 mg/day, which is lower than the calculated dose of 150 mg/day. Therefore, the prescribed dose of 25 mg 3 times a day is too low for this child. The dose should be adjusted to meet the correct dosage of 150 mg/day, which would be 50 mg 3 times a day. It is important not to titrate the dosage based on symptoms without consulting a physician, as this can lead to inappropriate medication administration.
