A nurse is collecting data from an infant a large patent ductus arteriosus. Which of the following is clinical manifestations should the nurse expect?

Machine like murmur

Chronic hypoxemia

Cyanosis with crying

Weak pulse

Answer and Explanation

The Correct Answer is A

A. Machine-like murmur.

This option is correct. A characteristic clinical manifestation of a large patent ductus arteriosus is a continuous "machine-like" murmur heard on auscultation. This murmur is typically heard best at the upper left sternal border and may radiate to the back.

B. Chronic hypoxemia.

Chronic hypoxemia is not typically a primary manifestation of a large PDA. While PDA can lead to increased pulmonary blood flow and potentially contribute to pulmonary congestion, chronic hypoxemia may not be a prominent feature unless complications such as heart failure develop.

C. Cyanosis with crying.

Cyanosis with crying is more commonly associated with cyanotic congenital heart defects such as tetralogy of Fallot. While PDA can contribute to cyanosis in certain circumstances, it is not typically a consistent clinical manifestation.

D. Weak pulse.

A weak pulse is not typically associated specifically with a large PDA. Infants with PDA may have bounding pulses due to increased blood flow through the ductus arteriosus.

Correct Answer is ["5.4"]

Explanation

Convert the child's weight from pounds (lb) to kilograms (kg):

20 lb × (1 kg / 2.20462 lb) ≈ 9.07 kg

Calculate the total daily dose of cefazolin:

Total daily dose = 30 mg/kg/day × 9.07 kg = 272.1 mg/day

Divide the total daily dose into two equal doses:

Each dose = 272.1 mg / 2 ≈ 136.05 mg

Determine the dose per ml using the available oral suspension concentration:

125 mg/5 ml = 25 mg/ml

Calculate the volume of oral suspension needed for each dose:

Volume per dose = Dose per dose / Concentration per ml

≈ 136.05 mg / 25 mg/ml

≈ 5.44 ml

So, the child should receive approximately 5.44 ml per dose of cefazolin oral suspension.

A. Instruct the client to cough B. Perform vibration while the client exhales slowly through the nose. C. Percuss the upper posterior chest. D. Administer albuterol by nebulizer.

Correct Answer is D

Explanation

A. Instruct the client to cough. Coughing is generally encouraged after chest physiotherapy to help expel loosened secretions, but it is not the first action. The bronchodilator should be administered first to maximize the effectiveness of the chest physiotherapy.

B. Perform vibration while the client exhales slowly through the nose. Vibration is a component of chest physiotherapy used to help loosen secretions during exhalation, but it is performed after the bronchodilator is administered and once the client is positioned properly.

C. Percuss the upper posterior chest.Percussion helps to mobilize secretions but is typically done after the bronchodilator has been administered to allow for more effective airway clearance.

D. Administer albuterol by nebulizer.Administering albuterol first dilates the airways, making it easier to mobilize and clear secretions during percussion, vibration, and postural drainage.
