A nurse is caring for a 2-month-old infant who has heart failure. Which of the following actions should the nurse take?
Limit oral feedings to 30 min in length.
Weigh the infant every other day.
Place the infant in the prone position for naps.
Check the infant’s oxygen saturation every 6 hr.
The Correct Answer is A
This is because infants with heart failure have difficulty feeding and may become exhausted or dyspneic during prolonged feedings. By limiting the feeding time, the nurse can reduce the energy expenditure and caloric needs of the infant.
Choice B is wrong because weighing the infant every other day is not enough to monitor the fluid status and nutritional intake of the infant. The nurse should weigh the infant daily at the same time using the same scale.
Choice C is wrong because placing the infant in a prone position can compromise respiratory function and increase the risk of sudden infant death syndrome (SIDS). The nurse should place the infant in a semi-Fowler’s position to facilitate breathing and decrease venous return.
Choice D is wrong because checking the infant’s oxygen saturation every 6 hr is not frequent enough to detect hypoxia or cyanosis. The nurse should monitor the oxygen saturation continuously or at least every 2 hr.

Correct Answer is B
Explanation
The correct answer is Choice B
Choice A rationale: Inserting the catheter without applying suction is correct technique. Suction should only be applied while withdrawing the catheter to prevent mucosal trauma and hypoxia. Initiating suction during insertion can damage tracheal lining and cause bradycardia due to vagal stimulation. Allowing clean insertion without suction reduces injury risk and supports effective secretion removal on withdrawal with controlled suction time.
Choice B rationale: Waiting 2 minutes between suction passes is too long and may delay secretion clearance, risking hypoxia and secretion buildup. Best practice is to wait about 30 seconds to 1 minute or until the client recovers baseline oxygen saturation and heart rate. Prolonged intervals may lead to atelectasis or respiratory distress in patients with poor reserve, especially if suctioning is incomplete or secretions are copious.
Choice C rationale: Suctioning should be limited to 10–15 seconds per pass to reduce hypoxemia and bronchospasm risks. Applying suction for 15 seconds falls within the upper acceptable range, particularly if preoxygenation is done. Extended suction beyond this can decrease PaO₂ levels rapidly. Limiting the suction time ensures safer removal of secretions while minimizing trauma and preserving adequate oxygenation.
Choice D rationale: Encouraging the client to cough facilitates mobilization of secretions toward the upper airway, making suctioning more effective. Coughing also enhances airway clearance naturally and may reduce the number of required suction passes. It is a therapeutic action in tracheostomy care that supports pulmonary hygiene, helps prevent atelectasis, and can reduce the need for deep suctioning interventions.
Correct Answer is B
Explanation
This is because rubella is a highly contagious viral infection that can cause serious harm to the developing fetus if the pregnant person gets infected. Rubella can cause congenital rubella syndrome, which can result in hearing and vision loss, heart defects and other serious conditions in newborns.
Choice A is wrong because aspirin should not be given to children or adolescents with viral infections, as it can cause Reye’s syndrome, a rare but potentially fatal condition that affects the liver and brain.
Choice C is wrong because rubella does not require airborne precautions, which are used for diseases that can spread through very small droplets that can remain in the air for long periods of time, such as tuberculosis or measles. Rubella spreads through direct contact with saliva or mucus of an infected person, or through respiratory droplets from coughing or sneezing.
Therefore, standard and droplet precautions are sufficient to prevent transmission. Choice D is wrong because Koplik spots are a characteristic sign of measles, not rubella.
Koplik spots are small white spots that appear on the inside of the cheeks before the measles rash develops. Rubella causes a pink or red rash that usually starts on the face and moves down the body.
Normal ranges for rubella antibody tests are:
- IgM: Negative or less than 0.9 IU/mL
- IgG: Negative or less than 10 IU/mL
A positive IgM result indicates a recent or current infection, while a positive IgG result indicates a past infection or immunity from vaccination.
