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. Suppress respiratory effort
Pancuronium is a neuromuscular blocking agent that is often used to induce paralysis in patients requiring mechanical ventilation. It works by blocking the transmission of nerve impulses at the neuromuscular junction, leading to skeletal muscle paralysis. In the context of a client with acute respiratory distress syndrome (ARDS) on mechanical ventilation, the use of pancuronium helps to suppress respiratory effort, allowing for better control of the patient's ventilation and oxygenation.
B. Decrease chest wall compliance:
Pancuronium does not directly affect chest wall compliance. It primarily acts on skeletal muscles, leading to paralysis.
C. Decrease respiratory secretions:
Pancuronium is not used to decrease respiratory secretions. It is a neuromuscular blocking agent with the main goal of inducing paralysis.
D. Induce sedation:
Pancuronium does not induce sedation. It works on the neuromuscular junction and does not have sedative properties. Sedation may be achieved with other medications, such as sedative agents.
Correct Answer is A
Explanation
A. Increased anteroposterior diameter of the chest
In emphysema, there is often hyperinflation of the lungs and destruction of the alveolar walls, leading to loss of lung elasticity. This results in increased air trapping and a characteristic "barrel chest" appearance, with an increased anteroposterior diameter.
B. Petechiae on chest:
Petechiae are small, red or purple spots caused by bleeding into the skin. They are not commonly associated with COPD and emphysema.
C. Oxygen saturation level 96%:
Oxygen saturation level of 96% is within the normal range. While oxygen saturation can be affected in COPD, the value provided is not indicative of severe hypoxemia.
D. Respiratory alkalosis:
Respiratory alkalosis is not typically associated with COPD and emphysema. In fact, respiratory acidosis is more commonly seen in these conditions due to impaired gas exchange and retention of carbon dioxide.
