A provider has written an order for a medication drip to be started at 12 units/kg/hour. Your client weighs 297 Ibs.
The medication is supplied as 25,000 units in 500 ml. At what rate would you set your pump?
26.7 ml/hour.
28.3 ml/hour.
30.5 ml/hour.
32.4 ml/hour.
The Correct Answer is B
To find the rate of the pump in ml/hour, you need to first convert the client’s weight from pounds to kilograms. You can do this by dividing the weight by 2.2046 or multiplying it by 0.454.
For example:
297 lbs / 2.2046 = 134.72 kg or 297 lbs x 0.454 = 134.72 kg
Then, you need to multiply the client’s weight in kilograms by the ordered dose in units/kg/hour to get the total units per hour.
For example:
134.72 kg x 12 units/kg/hour = 1616.64 units/hour
Next, you need to set up a proportion to find the rate of the pump in ml/hour using the supplied medication concentration.
For example:
25,000 units / 500 ml = 1616.64 units / X ml Cross-multiply and solve for X:
25,000 x X = 808320 X = 808320 / 25000 X = 32.33 ml/hour
Finally, you need to round your answer to the nearest tenth of a ml/hour as per the medication administration guidelines.
For example:
32.33 ml/hour ≈ 32.3 ml/hour
Therefore, the rate of the pump is 32.3 ml/hour.
Choice A is wrong because it uses a different conversion factor for pounds to kilograms (1 lb = 0.5 kg) which is not accurate.
Choice C is wrong because it uses a different ordered dose (10 units/kg/hour) which is not what the provider has written.
Choice D is wrong because it uses a different supplied medication concentration (20,000 units in 500 ml) which is not what is available.

Correct Answer is A
Explanation
“I will discard unused pills after six months after replacing it with a new vial.” This statement indicates that the client understands that nitroglycerin tablets lose their potency over time and need to be replaced regularly.
Choice B is wrong because nitroglycerin can cause headaches as a side effect, but the client should not stop taking it if they have chest pain. They can use Tylenol for pain relief.
Choice C is wrong because nitroglycerin can cause hypotension and dizziness, so the client should avoid lying down or changing positions suddenly after taking it. They should sit or stand still until the chest pain subsides.
Choice D is wrong because a tingling feeling on the tongue is a normal sensation when taking sublingual nitroglycerin and does not indicate an adverse reaction. It also confirms that the tablet is potent and effective.
Correct Answer is B
Explanation
The nurse should make the statement “The client has hypoxemia after 10 minutes on a rebreather mask.” first. This is because SBAR (Situation- Background-Assessment-Recommendation) is a communication tool that helps provide essential, concise information, usually during crucial situations. The first component of SBAR is Situation, which is a concise statement of the problem.
The nurse should state the most urgent and relevant problem first, which is the client’s hypoxemia.
Choice A is wrong because it is not a clear statement of the situation.
It is vague and does not provide specific information about the client’s condition or vital signs.
It also expresses the nurse’s feeling rather than an objective assessment.
Choice C is wrong because it is part of the Assessment component of SBAR, not the Situation.
It provides numerical data about the client’s blood gas analysis, but it does not state the problem or the reason for calling the healthcare provider.
Choice D is wrong because it is part of the Background component of SBAR, not the Situation.
It provides pertinent and brief information related to the situation, such as the client’s medical history and diagnosis, but it does not state the current problem or concern.
Normal ranges for blood gas analysis are:
- PaO2: 80-100 mmHg
- PaCO2: 35-45 mmHg
- HCO3: 22-26 mEq/L
Hypoxemia is defined as a low level of oxygen in the blood, usually below 60 mmHg.
