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.

A patient admitted to the hospital with myocardial infarction develops severe pulmonary edema. Which of the following symptoms should the nurse expect the patient to exhibit?
- A. Slow, deep respirations
- B. Stridor
- C. Bradycardia
- D. Air hunger
Correct Answer: D
Rationale: In a patient with pulmonary edema following a myocardial infarction, the nurse should expect symptoms such as air hunger, anxiety, and agitation. Air hunger refers to the feeling of needing to breathe more deeply or more often. Other symptoms of pulmonary edema can include coughing up blood or bloody froth, orthopnea (difficulty breathing when lying down), and paroxysmal nocturnal dyspnea (sudden awakening with shortness of breath). Slow, deep respirations (Choice A) are not typical in pulmonary edema; these patients often exhibit rapid, shallow breathing due to the difficulty in oxygen exchange. Stridor (Choice B) is a high-pitched breathing sound often associated with upper airway obstruction, not typically seen in pulmonary edema. Bradycardia (Choice C), a slow heart rate, is not a characteristic symptom of pulmonary edema, which is more likely to be associated with tachycardia due to the body's compensatory response to hypoxia and increased workload on the heart.
What preparation should be made for a client undergoing a KUB (Kidney, Ureter, Bladder) radiography test?
- A. Client must be NPO before the examination
- B. Enema should be administered before the examination
- C. Medicate the client with furosemide 20 mg IV 30 minutes before the examination
- D. No special orders are necessary for this examination
Correct Answer: D
Rationale: The correct answer is that no special orders are necessary for a KUB radiography test. It is important to inform the client to remove any clothing, jewelry, or objects that may interfere with the test. Option A is incorrect because there is no need for the client to be NPO before this examination. Option B is incorrect as enemas are not routinely administered prior to a KUB radiography test. Option C is incorrect as there is no need to medicate the client with furosemide before this examination.
In a pediatric clinic, a nurse is assessing a child recently diagnosed with cystic fibrosis. Which of the following later findings of this disease would the nurse not expect to see at this time?
- A. Positive sweat test
- B. Bulky greasy stools
- C. Moist, productive cough
- D. Meconium ileus
Correct Answer: C
Rationale: In a child newly diagnosed with cystic fibrosis (CF), noisy respirations and a dry, non-productive cough are typically the first respiratory signs to appear. The other options, including a positive sweat test, bulky greasy stools, and meconium ileus, are among the earliest findings of CF. CF is a genetic condition that affects the production of mucus, sweat, saliva, and digestive juices. Due to a defective gene, these secretions become thick and sticky instead of thin and slippery, leading to blockages in various passageways, especially in the pancreas and lungs. Respiratory failure is a severe consequence of CF, making it crucial to monitor respiratory symptoms closely in affected individuals. Therefore, a moist, productive cough would not be an expected finding in a newly diagnosed child with CF.
A nurse has just started her rounds delivering medication. A new patient on her rounds is a 4-year-old boy who is non-verbal. This child does not have any identification on. What should the nurse do?
- A. Contact the provider
- B. Ask the child to write their name on paper
- C. Ask a coworker about the identification of the child
- D. Ask the father who is in the room the child's name
Correct Answer: D
Rationale: When encountering a non-verbal child without identification, it is appropriate for the nurse to ask the accompanying parent or guardian for the child's name. The father, being present in the room, can provide the necessary information. This ensures accurate identification to deliver the correct medication. Contacting the provider may cause unnecessary delays. Asking a non-verbal child to write their name is not feasible. Asking a coworker may not provide reliable identification as they may not have direct knowledge.
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.
