A nurse is preparing to administer amoxicillin 250 mg PO. Available is amoxicillin oral suspension 125 mg/5 mL. How many ml. should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Inhale rapidly when using the spacer with the MDI. Inhalation should be slow and deep to allow the medication to be delivered effectively to the lungs. Rapid inhalation can cause the medication to be deposited in the oropharynx instead.
B. The spacer increases the amount of medication delivered to the lungs. A spacer helps to improve medication delivery to the lungs by allowing more time for the medication to be inhaled and reducing deposition in the mouth and throat.
C. The spacer increases the amount of medication delivered to the oropharynx. The spacer actually reduces the amount of medication delivered to the oropharynx by holding the medication in a chamber, allowing for more medication to reach the lungs.
D. Cover exhalation slots of the spacer with lips when inhaling. The exhalation slots should remain open to allow for normal breathing. The child should create a good seal around the mouthpiece but not block any slots.

A. Stimulates secretions: Expectorants work by thinning and loosening mucus in the airways, making it easier to cough up and clear out. This mechanism helps to reduce cough by facilitating the removal of mucus.
B. Suppresses the urge to cough: Cough suppressants, or antitussives, work by suppressing the cough reflex, not by stimulating secretions. This choice describes a different type of medication used for dry, unproductive coughs.
C. Reduces inflammation: Anti-inflammatory medications reduce inflammation, but they do not specifically target mucus production or the cough reflex. Expectorants do not primarily work by reducing inflammation.
D. Dries mucous membranes: Drying mucous membranes would typically be the action of antihistamines or decongestants, which are not the primary mechanism of action for expectorants. Expectorants aim to keep mucus hydrated to facilitate its removal.
