A client is to receive 250,000 units of benzathine penicillin.
G. The medication is available in a vial containing 300,000 units per milliliter. How many milliliters should a nurse administer?
0.4.
0.8.
1.2.
1.6.
The Correct Answer is B
0.8.
To find the answer, you need to use the formula: Dose ordered / Dose available = Volume to administer
In this case, the dose ordered is 250,000 units and the dose available is 300,000 units/mL. So, you need to divide 250,000 by 300,000 and get 0.8333.
Then, you need to round it to one decimal place and get 0.8 mL. Choice A is wrong because it is too low.
If you administer 0.4 mL, you will give only 120,000 units of penicillin G benzathine, which is half of the prescribed dose.
Choice C is wrong because it is too high.
If you administer 1.2 mL, you will give 360,000 units of penicillin G benzathine, which is 44% more than the prescribed dose.
Choice D is wrong because it is also too high.
If you administer 1.6 mL, you will give 480,000 units of penicillin G benzathine, which is almost double the prescribed dose.
The normal range for penicillin G benzathine dosage depends on the type and severity of infection, but it is usually between 50,000 and 2.4 million units per injection.

Correct Answer is D
Explanation
The client with a labored respiratory rate of 28 should be seen first because this indicates respiratory distress, which is a life-threatening condition that requires immediate intervention. Respiratory rate is one of the vital signs that are used to assess the severity of a patient’s condition and to triage them accordingly. A normal respiratory rate for an adult is 12 to 20 breaths per minute.
Choice A is wrong because a large laceration on the left scapula is not as urgent as respiratory distress.
A laceration is a wound that involves a cut or tear in the skin, which may cause bleeding, pain, and infection. However, it can be managed with wound care and suturing in the urgent care center.
Choice B is wrong because a compound fracture of the right tibia is not as urgent as respiratory distress.
A compound fracture is a fracture that breaks through the skin, which may cause bleeding, pain, infection, and nerve or blood vessel damage. However, it can be stabilized with splinting and dressing in the urgent care center before transferring to a hospital for further treatment.
Choice C is wrong because being unable to breastfeed a 4 week old is not as urgent as respiratory distress.
Breastfeeding difficulties may be caused by various factors, such as poor latch, low milk supply, sore nipples, or mastitis. However, they can be managed with education, support, and medication in the urgent care center.
Correct Answer is C
Explanation
The client received a dose of clopidogrel at 2200. Clopidogrel is an antiplatelet drug that increases the risk of bleeding during and after a liver biopsy. The healthcare provider should be informed of this medication and decide whether to postpone the biopsy or administer reversal agents.
Choice A is wrong because being NPO since 2300 is a standard preparation for a liver biopsy.
Choice B is wrong because pain in the left lower quadrant and constipation are not related to the liver biopsy and do not pose an immediate risk.
Choice D is wrong because having an allergy is not relevant to the liver biopsy unless it is an allergy to the local anesthetic or contrast agent used.
