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 C
Explanation
A. Metallic taste in the mouth:
This is not a typical finding of oxygen toxicity. Metallic taste may be associated with other factors but is not a specific indicator of oxygen toxicity.
B. Facial flushing:
Facial flushing is not a typical finding in oxygen toxicity. It is more commonly associated with other conditions, such as certain allergic reactions or vasodilation.
C. Muscle twitching
Muscle twitching, also known as myoclonus, is a recognized symptom of central nervous system oxygen toxicity. High concentrations of oxygen, particularly at increased pressures, can cause neurotoxic effects leading to muscle twitching, dizziness, and even convulsions.
D. Periorbital edema:
Periorbital edema is not a common manifestation of oxygen toxicity. It is more commonly associated with conditions related to fluid balance or kidney function.
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.
