The practical nurse (PN) is preparing cefazolin 400 mg IM for a client with a gram-positive infection. The available vial is labeled, "Cefazolin 1 gram," and the instructions for reconstitution state, for IM use, add 2 mL sterile water for injection. Total volume after reconstitution is 2.5 mL. After reconstitution, how many mL should be administered to the client? (Enter numeric value only. If rounding is required, round to the whole number, nearest tenths/hundredth).
The Correct Answer is ["1"]
This is the correct answer because the concentration of cefazolin after reconstitution is 1 gram/2.5 mL, which is equivalent to 400 mg/1 mL. Therefore, to administer 400 mg of cefazolin, the PN should draw up 1 mL of the reconstituted solution. This can be calculated using the formula:
Desired dose / Available dose = Volume to administer
400 mg / 1000 mg = x mL / 2.5 mL
x = (400 x 2.5) / 1000
x = 1 mL

Correct Answer is B
Explanation
Choice A rationale:
Emphasize that using safe sex practices removes the risk of STIs. Rationale: While promoting safe sex practices is essential in preventing STIs, this response is not directly addressing the client's situation. The client already reports having unprotected sex, so this choice does not provide relevant information or address the potential consequences.
Choice B rationale:
Explain that reinfections occur from sex with untreated partners. Rationale: This is the correct response. Syphilis is a sexually transmitted infection that can be treated with antibiotics, but reinfections can occur if sexual partners are not treated. This response provides essential information about the potential consequences of unprotected sex with untreated partners.
Choice C rationale:
Clarify that all STIs are transmitted through sexual intercourse. Rationale: While this statement is accurate in a general sense, it does not specifically address the client's situation or the risks associated with syphilis. It lacks the focus needed to educate the client effectively about their current situation.
Choice D rationale:
Provide counseling that most contraceptives protect against infection. Rationale: This response is inaccurate. Contraceptives primarily aim to prevent pregnancy, not protect against STIs. Therefore, it does not address the client's concern or provide relevant information about syphilis.
Correct Answer is B
Explanation
Choice A rationale:
“I should take this medication with food to prevent stomach upset.” Rationale: This statement is not accurate for fluconazole. While some medications should be taken with food to reduce stomach upset, fluconazole is typically taken on an empty stomach. Taking it with food may reduce its absorption.
Choice B rationale:
“I should avoid drinking alcohol while taking this medication.” Rationale: This is the correct response. Fluconazole can interact with alcohol and may lead to increased side effects or reduced effectiveness of the medication. Therefore, it is essential to avoid alcohol while taking fluconazole.
Choice C rationale:
“I should use a barrier method of contraception while taking this medication.” Rationale: While it is generally a good practice to use barrier contraception during treatment for a fungal infection to prevent potential spread to a partner, this statement does not specifically address fluconazole's requirements or interactions.
Choice D rationale:
“I should stop taking this medication if I develop a rash.” Rationale: This statement is not entirely accurate. While it is important to monitor for skin rashes as they can be a sign of an allergic reaction, the decision to stop taking fluconazole should be made in consultation with a healthcare provider. It is not an automatic response to developing a rash.
