A nurse is assessing a child whose history reveals an upper respiratory illness that has progressed to a persistent cough characterized by an inspiratory whoop. The nurse would suspect which of the following?

Pertussis

Asthma

Bronchiolitis

Acute Laryngotraceobronchitis (LTB)

Answer and Explanation

The Correct Answer is A

A. Pertussis:

Pertussis, commonly known as whooping cough, is caused by the bacterium Bordetella pertussis. It is characterized by a persistent cough with a distinctive "whoop" sound during the inspiratory phase. The cough can be severe and may last for several weeks. The characteristic whooping sound is due to the rapid intake of breath after a coughing episode.

B. Asthma:

Asthma is a chronic respiratory condition characterized by recurrent episodes of wheezing, coughing, and shortness of breath. It is not typically associated with a whooping sound during the inspiratory phase. Asthma symptoms are often triggered by factors such as allergies, exercise, or exposure to irritants.

C. Bronchiolitis:

Bronchiolitis is commonly caused by respiratory syncytial virus (RSV), especially in infants. It presents with symptoms such as cough, wheezing, and respiratory distress. However, it does not involve the characteristic whooping cough sound seen in pertussis.

D. Acute Laryngotracheobronchitis (LTB):

Acute Laryngotracheobronchitis, or croup, is characterized by a barking cough, stridor (a high-pitched sound during inhalation), and respiratory distress. It is common in young children and is often caused by viruses. Unlike pertussis, it does not typically include the distinctive whooping sound.

Correct Answer is ["612.375"]

Explanation

To calculate the ordered dose of Ceftriaxone in mg/kg/day, we can follow these steps:

Convert the weight to kg:

Weight in kg= Weight in lbs /2.2046

Weight in kg= 18lbs/2.2046≈8.165 kg

Calculate the daily dosage range:

Using the recommended dosage range of 50-75 mg/kg/day:

Minimum daily dosage= 50mg/kg/day × Weight in kg

Maximum daily dosage =75mg/kg/day×Weight in kg

Calculate the ordered dose:

Ordered dose=Dosage per administration × Frequency per day

Ordered dose= 300mg×2times per day= 600mg/day

Now, let's calculate the daily dosage range:

Minimum daily dosage=50mg/kg/day×8.165kg=408.25mg/day

Maximum daily dosage=75mg/kg/day×8.165kg=612.375mg/day

The ordered dose of 600 mg/day falls within the calculated range of 408.25-612.375 mg/day, so the ordered dose is within the recommended dosage range for a serious infection.

Therefore, the ordered dose of Ceftriaxone 300 mg IV Q12H for a 6-month-old infant weighing 18 lbs is considered safe based on the calculated dosage range.

A. The nurse applies elbow restraints to the infant. B. The nurse soaks the skin with warm water. C. The nurse follows contact precautions. D. The nurse applies topical antibiotics to the lesions.

Correct Answer is C

Explanation

A. The nurse applies elbow restraints to the infant:

The use of elbow restraints is not a standard intervention for impetigo. Restraints are typically used for specific medical reasons, such as preventing the infant from interfering with medical equipment or procedures. It is not the highest priority in managing impetigo.

B. The nurse soaks the skin with warm water:

Soaking the skin with warm water can help in keeping the affected areas clean and promoting healing, but it is not the highest priority when considering the prevention of the spread of impetigo.

C. The nurse follows contact precautions:

Following contact precautions is the highest priority when dealing with impetigo. Since impetigo is highly contagious, implementing contact precautions, such as wearing appropriate PPE, is crucial to prevent the spread of the infection within the hospital setting.

D. The nurse applies topical antibiotics to the lesions:

Applying topical antibiotics is an important part of the treatment for impetigo. It helps to eliminate the bacterial infection and promote healing. However, while important, it is not the highest priority compared to preventing the spread of the infection through contact precautions.
