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.)

Answer and Explanation

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 D

Explanation

Choice A Reason: This is incorrect because it is too early. Naegele's rule is a formula that estimates the date of birth by adding one year, subtracting three months, and adding seven days to the date of the last menstrual period. Applying this rule to April 11 gives February 18, not February 24.

Choice B Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 18.

Choice C Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 25.

Choice D Reason: This is correct because it follows Naegele's rule. Adding one year, subtracting three months, and adding seven days to April 11 gives February 18.

A. It is primarily transmitted through mosquitoes. B. It is primarily transmitted through accidental puncture wounds. C. It is primarily transmitted through sexual contact. D. It is primarily transmitted through respiratory droplets.

Correct Answer is C

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 correct because sexual contact 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.

Choice D Reason: This is incorrect because respiratory droplets do not transmit HIV. HIV is not an airborne virus and cannot be spread by coughing, sneezing, or breathing. HIV cannot be transmitted by casual contact, such as hugging, kissing, or sharing utensils.
