A nurse is preparing to measure an infant’s vital signs.
The nurse should use which of the following sites to assess a heart rate?

The correct answer is Choice B.

Choice A rationale

Montelukast is a leukotriene receptor antagonist used for long-term control and prevention of asthma symptoms. It is not a rescue medication and does not provide immediate relief during an acute asthma attack. Montelukast works by reducing inflammation and preventing bronchoconstriction, but its effects are not rapid enough to address the immediate needs of a patient experiencing an acute asthma attack.

Choice B rationale

Albuterol is a short-acting beta-agonist (SABA) that provides rapid bronchodilation and is the first-line treatment for acute asthma attacks. It works by relaxing the smooth muscles in the airways, leading to quick relief of bronchospasm and improved airflow. Administering albuterol promptly can help alleviate symptoms and prevent the progression of an asthma attack, making it the priority medication in this scenario.

Choice C rationale

Fluticasone is an inhaled corticosteroid used for long-term control of asthma. It helps reduce inflammation in the airways and prevent asthma symptoms but is not effective as a rescue medication during an acute asthma attack. Inhaled corticosteroids are typically used as part of a daily maintenance regimen to manage chronic asthma and prevent exacerbations.

Choice D rationale

Budesonide is another inhaled corticosteroid used for long-term asthma control. Like fluticasone, it helps reduce airway inflammation and prevent asthma symptoms but is not suitable for immediate relief during an acute asthma attack. Inhaled corticosteroids are

important for managing chronic asthma but do not provide the rapid bronchodilation needed in an emergency situation.

The correct answer is B. Bring your baby in to the clinic today.

Choice A rationale

Giving an oral rehydration solution is not appropriate without first assessing the infant. Projectile vomiting in a 2-month-old could indicate a serious condition such as pyloric stenosis, which requires medical evaluation.

Choice B rationale

Bringing the baby to the clinic today is the appropriate response. Projectile vomiting in an infant can be a sign of a serious condition that requires prompt medical evaluation and treatment.

Choice C rationale

Switching to a different formula is not appropriate without first assessing the infant. Projectile vomiting could indicate a serious condition that needs to be evaluated by a healthcare provider.

Choice D rationale

Burping the baby more frequently during feedings may help with minor feeding issues, but it is not appropriate advice for projectile vomiting. The infant needs to be evaluated by a healthcare provider to determine the cause of the vomiting.
