A nurse is preparing to administer morphine 8 mg IV intermittent bolus to a client. The amount available is morphine 10 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.8"]
To calculate the amount of morphine to administer, we can use the following formula:
Amount of medication (mL) = Desired dose (mg) / Concentration (mg/mL)
In this case, the desired dose is 8 mg and the concentration is 10 mg/mL.
Amount of medication (mL) = 8 mg / 10 mg/mL
Amount of medication (mL) = 0.8 mL
Therefore, the nurse should administer 0.8 mL of morphine.

Correct Answer is C
Explanation
Flumazenil is the antidote for diazepam, which is a benzodiazepine. Flumazenil is a selective antagonist that can reverse the sedative effects of benzodiazepines and is commonly used in cases of benzodiazepine overdose or to reverse sedation after procedures.
Naloxone (A) is the antidote for opioid overdose and would not be appropriate for reversing the effects of diazepam.
Atropine (B) is an anticholinergic medication used to increase heart rate and is not specific to the reversal of diazepam sedation.
Neostigmine (D) is a cholinesterase inhibitor used to reverse the effects of non-depolarizing neuromuscular blocking agents and is not indicated for reversing the effects of diazepam.
Correct Answer is A
Explanation
A client with a magnesium level of 3.2 mEq/L has a higher-than-normal magnesium level, indicating hypermagnesemia. The nurse should expect to administer calcium gluconate.
Calcium gluconate is the antidote for hypermagnesemia, as it works to antagonize the effects of magnesium on the body. By administering calcium gluconate, the nurse can help counteract the effects of excess magnesium and normalize the client's magnesium levels.
Let's go through the other options:
B. Calcitonin: Calcitonin is not used to treat hypermagnesemia. Calcitonin is a hormone that regulates calcium and phosphorus levels in the body. It is used in certain conditions, such as hypercalcemia (high calcium levels), but it is not indicated for hypermagnesemia.
C. Magnesium oxide: Magnesium oxide is a form of magnesium supplement, and it is not appropriate for a client with hypermagnesemia, as it would further increase the magnesium level, exacerbating the condition.
D. Magnesium sulphate: Magnesium sulfate is also not appropriate for a client with hypermagnesemia, as it would further elevate the magnesium levels in the body. Magnesium sulfate is often used to treat magnesium deficiency or as a tocolytic agent to prevent premature labor.
