An 8-month-old infant is receiving Digoxin. The nurse should notify the practitioner and withhold the medication if the apical pulse is less than which of the following?
90 bpm
60 bpm
120 bpm
100 bpm
The Correct Answer is D
A. 90 bpm is too low for an 8-month-old infant and not the standard threshold for withholding digoxin in this age group.
B. 60 bpm is the cutoff for adults, not infants.
C. 120 bpm is normal for an infant and does not warrant holding digoxin.
D. Correct. For infants, digoxin should be withheld and the provider notified if the apical heart rate is less than 100 beats per minute, due to the risk of bradycardia and digoxin toxicity.

Correct Answer is B
Explanation
A. Cochlear implants are used to treat sensorineural hearing loss, which involves damage to the inner ear or auditory nerve. Conductive hearing loss is usually treated with medical or surgical intervention, such as tubes or hearing aids.
B. Conductive hearing loss occurs when sound waves cannot effectively reach the inner ear, often due to fluid, wax, or structural issues. Otitis media with effusion (fluid in the middle ear without infection) is a common cause of temporary conductive hearing loss in children.
C. Auditory nerve damage causes sensorineural hearing loss, not conductive.
D. While some hearing losses are inherited, conductive hearing loss is typically caused by external or middle ear problems, not genetic factors.
Correct Answer is C
Explanation
A. Budesonide is an inhaled corticosteroid used for long-term control of asthma. It is not effective in acute situations where rapid bronchodilation is needed.
B. Montelukast is a leukotriene receptor antagonist used for daily maintenance therapy and prevention of asthma symptoms, not for acute attacks.
C. Albuterol is a short-acting beta-2 agonist (SABA) that provides rapid bronchodilation. It is the first-line medication during an acute asthma attack to relieve bronchospasm quickly.
D. Fluticasone is also an inhaled corticosteroid, used for long-term asthma control, and is not appropriate as the first-line treatment in an emergency asthma situation.
