A nurse is preparing to administer amoxicillin 250 mg PO every 8 hr. The amount available is amoxicillin 125 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)
The Correct Answer is ["2 "]
To calculate the number of tablets that the nurse should administer with each dose, the nurse needs to use the formula:
D/H x Q = X
where D is the desired dose, H is the dose on hand, Q is the quantity of the drug, and X is the amount to give.
In this case, D is 250 mg, H is 125 mg, Q is 1 tablet, and X is unknown. Plugging these values into the formula, we get:
250/125 x 1 = X
Simplifying, we get:
2 = X
Therefore, the nurse should administer 2 tablets with each dose of amoxicillin.

Correct Answer is A
Explanation
A. “I have not received any of my medications today.”
The statement "I have not received any of my medications today" requires follow-up from the nurse because it indicates a potential issue with the client's medication administration. It's important to ensure that the client receives the prescribed medications in a timely manner.
B. “Do you know when I will be going home?”
This is a question about the discharge plan and does not indicate an immediate issue that requires follow-up.
C. “I do not know how to make the remote control work.”
While it's a statement about the client's understanding of the remote control, it is not an urgent matter that requires immediate attention.
D. “My dressing was changed earlier this morning.”
This statement indicates that a care task (dressing change) has been completed and does not suggest a problem that requires urgent follow-up.
Correct Answer is B
Explanation
A. An increase in the CMV rate:
Increasing the continuous mandatory volume (CMV) rate would provide more mandatory breaths, which may not address the patient's respiratory acidosis. It could potentially worsen the situation by causing respiratory alkalosis.
B. Change to SIMV (Synchronized Intermittent Mandatory Ventilation) MODE
The patient's arterial blood gas results indicate respiratory acidosis with an elevated PaCO2 (50 mmHg) and a low pH (7.30). The nurse would recommend changing to SIMV mode to allow for spontaneous breaths in addition to the set mandatory breaths. This change helps the patient to have more control over their respiratory efforts and may assist in lowering the PaCO2.
C. A decrease in the PaO2:
Decreasing the partial pressure of oxygen (PaO2) is not an appropriate response, especially when the patient is already on mechanical ventilation and has a moderate PaO2 level. The primary concern is the elevated PaCO2 and respiratory acidosis.
D. A decrease in the CMV rate:
Decreasing the CMV rate would reduce the number of mandatory breaths, potentially allowing the patient to hypoventilate further and retain more carbon dioxide. This is not the appropriate intervention for a patient with respiratory acidosis.
