A nurse is preparing to administer penicillin G benzathine 1.2 million units IM now. The amount available is penicillin G benzathine 600,000 units/mL. How many mL should the nurse administer?
(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"]
The correct answer is 2 mL. To calculate the volume to administer, the nurse should use the following formula:
Volume (mL) = Dose (units) / Concentration (units/mL)
Plugging in the given values, we get:
Volume (mL) = 1,200,000 units / 600,000 units/mL
Volume (mL) = 2 mL
Rounding to the nearest whole number, we get 2 mL.

Correct Answer is ["2"]
Explanation
To calculate how many capsules to administer per dose, the nurse should divide the ordered dose by the available dose and round to the nearest whole number.
The ordered dose is 50 mg.
The available dose is 25 mg per capsule.
Therefore, the number of capsules to administer per dose is 50 mg / 25 mg = 2 capsules.
The answer should be rounded to the nearest whole number and use a leading zero if it applies. Do not use a trailing zero.
Therefore, the final answer is 2 capsules.
Correct Answer is D
Explanation
Choice A Reason: This is incorrect because mosquitoes do not transmit HIV. HIV is a virus that infects human cells and cannot survive in insects. Mosquitoes do not inject blood from one person to another when they bite, but only saliva that contains anticoagulants and enzymes.
Choice B Reason: This is incorrect because accidental puncture wounds are not a common mode of HIV transmission. HIV can be transmitted through exposure to infected blood or body fluids, such as through needle sharing, blood transfusion, or occupational injury. However, these cases are rare and can be prevented by using sterile equipment, screening blood products, and following universal precautions.
Choice C Reason: This is incorrect because casual contact is not a mode of HIV transmission. HIV is not an airborne virus and cannot be spread by coughing, sneezing, or breathing. HIV cannot be transmitted by hugging, kissing, or sharing utensils.
Choice D Reason: This is correct because direct contact with infected body fluids is the most common mode of HIV transmission. HIV can be transmitted through unprotected vaginal, anal, or oral sex with an infected person, as these activities can involve contact with infected blood, semen, vaginal fluid, or pre-ejaculate. HIV can also be transmitted through sharing needles or syringes with an infected person, or from mother to child during pregnancy, childbirth, or breastfeeding.
