A nurse is preparing to administer amoxicillin 2 g/day PO divided into two doses. The amount available is amoxicillin 500 mg tablets.

How many tablets should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A Reason:

Repeating auscultation after asking the client to take a deep breath and cough is the first intervention the nurse should take. This action helps to clear any secretions or mucus that might be causing the crackles. If the crackles persist after the client coughs, it indicates that the sounds are likely due to fluid in the lungs, which requires further assessment and intervention. This step ensures that the nurse accurately identifies the cause of the crackles before proceeding with other interventions.

Choice B Reason:

Instructing the client to limit fluid intake to less than 2,000 mL/day might be appropriate in cases of fluid overload or heart failure, but it is not the first intervention. The nurse needs to confirm the cause of the crackles before making any recommendations about fluid intake. Limiting fluid intake without proper assessment could lead to dehydration and other complications.

Choice C Reason:

Placing the client on bed rest in semi-Fowler’s position can help improve lung expansion and oxygenation by reducing pressure on the diaphragm. However, this is not the first intervention. The nurse should first determine if the crackles are due to secretions that can be cleared by coughing. Semi-Fowler’s position is beneficial for patients with respiratory distress, but it does not address the immediate need to reassess lung sounds.

Choice D Reason:

Preparing to administer antibiotics is not the first intervention. Antibiotics are used to treat infections, and the nurse needs to confirm whether the crackles are due to an infection or another cause before administering medication. Immediate administration of antibiotics without proper assessment could lead to inappropriate treatment and antibiotic resistance.

Choice A reason: The glossopharyngeal nerve (CN IX) is primarily responsible for the gag reflex. It provides sensory input from the pharynx and posterior third of the tongue, which triggers the gag reflex when stimulated. This nerve plays a crucial role in swallowing and the reflexive action to prevent choking.

Choice B reason: The trigeminal nerve (CN V) is responsible for facial sensation and motor functions such as biting and chewing. It does not play a direct role in the gag reflex. While it is important for other sensory and motor functions, it is not involved in the reflex being assessed here.

Choice C reason: The vagus nerve (CN X) also contributes to the gag reflex by providing motor innervation to the muscles of the pharynx and larynx. However, the primary sensory input for the gag reflex comes from the glossopharyngeal nerve (CN IX). The vagus nerve works in conjunction with CN IX to complete the reflex action.

Choice D reason: The hypoglossal nerve (CN XII) controls the movements of the tongue. It is essential for speech and swallowing but does not have a role in the gag reflex. The hypoglossal nerve’s primary function is motor control of the tongue muscles.
