Nokea
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.

What intervention should the nurse implement while a client is having a grand mal seizure?
- A. Open the jaw and place a bite block between the teeth
- B. Try to place the client on his side
- C. Restrain the client to prevent injury
- D. Place pillows around the client
Correct Answer: B
Rationale: During a grand mal seizure, the client is at risk of injury due to severe, involuntary muscle spasms and contractions. It is crucial for the nurse to avoid restraining the client or inserting objects into their mouth, as these actions may lead to further harm. Placing the client on their side can help facilitate the drainage of oral secretions and assist in maintaining an open airway, reducing the risk of aspiration. Restraint should be avoided as it can exacerbate muscle contractions and increase the risk of injury. Placing pillows around the client may not provide adequate support or protection during the seizure, making it a less effective intervention compared to positioning the client on their side.
A nurse in the emergency department is observing a 4-year-old child for signs of increased intracranial pressure after a fall from a bicycle, resulting in head trauma. Which of the following signs or symptoms would be cause for concern?
- A. Bulging anterior fontanel
- B. Repeated vomiting
- C. Signs of sleepiness at 10 PM
- D. Inability to read short words from a distance of 18 inches
Correct Answer: B
Rationale: Increased intracranial pressure after head trauma can lead to serious complications. Repeated vomiting is a concerning sign as it can indicate stimulation of the vomiting center within the brainstem due to increased pressure. This can be an early indicator of raised intracranial pressure and the need for urgent medical intervention. Bulging anterior fontanel may not be immediately apparent in a 4-year-old child and is more common in infants. Signs of sleepiness at a particular time of day are not specific to increased intracranial pressure. Inability to read short words from a distance of 18 inches may indicate vision problems but is not directly related to intracranial pressure.
The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?
- A. Narrowed QRS complex
- B. Shortened "PR"? interval
- C. Tall peaked "T"? waves
- D. Prominent "U"? waves
Correct Answer: C
Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.
A patient underwent fiberoptic colonoscopy 18 hours ago and presents to the emergency department with increasing abdominal pain, fever, and chills. Which of the following conditions poses the most immediate concern?
- A. Bowel perforation
- B. Viral gastroenteritis
- C. Colon cancer
- D. Diverticulitis
Correct Answer: A
Rationale: The correct answer is bowel perforation. Bowel perforation is the most serious complication of fiberoptic colonoscopy, with signs such as progressive abdominal pain, fever, chills, and tachycardia indicating advancing peritonitis. Although colonoscopic perforation is rare (0.03% to 0.7% incidence), it can lead to high mortality and morbidity rates. Viral gastroenteritis (Choice B) typically presents with symptoms like diarrhea, nausea, vomiting, and abdominal cramps, but it is not the most immediate concern in this scenario. Colon cancer (Choice C) and diverticulitis (Choice D) are important conditions but are less likely to present acutely after colonoscopy compared to bowel perforation.
A patient is getting discharged from a skilled nursing facility (SNF). The patient has a history of severe COPD and PVD. The patient is primarily concerned about his ability to breathe easily. Which of the following would be the best instruction for this patient?
- A. Deep breathing techniques to increase oxygen levels.
- B. Cough regularly and deeply to clear airway passages.
- C. Cough following bronchodilator utilization.
- D. Decrease CO2 levels by increasing oxygen intake during meals.
Correct Answer: C
Rationale: The correct answer is to instruct the patient to cough following bronchodilator utilization. In COPD and PVD patients, bronchodilators help to open up the airways, making coughing more effective in clearing secretions from the lungs. This instruction can aid in improving the patient's ability to breathe by enhancing airway clearance. Deep breathing techniques (Choice A) may help increase oxygen levels but may not directly address the patient's immediate concern of breathing difficulty. Coughing regularly and deeply (Choice B) can be beneficial, but the timing following bronchodilator use is more crucial to maximize its effectiveness. Decreasing CO2 levels by increasing oxygen intake during meals (Choice D) does not directly address the patient's concern about breathing ease or the role of bronchodilators in improving cough effectiveness.
