A client is to receive enoxaparin 30 mg subcutaneously. Available is enoxaparin 40 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.8"]
- To find out how many mL to administer for a medication dose, we need to use this formula: mL = (dose in mg) / (concentration in mg/mL)
- In this formula, the dose in mg is the amount of medication ordered by the provider, and concentration in mg/mL is the strength of medication available in the vial or syringe.
- We plug in the given values into this formula: mL = (30 mg) / (40 mg/mL)
- We simplify and solve this equation: mL = 0.75 mL
- We round off to the nearest tenth: mL = **0.8 mL**
- We add a leading zero if needed: mL = **0.8 mL**
- We do not add a trailing zero: mL = **0.8 mL**

Correct Answer is C
Explanation
Choice A: "Store your condoms in your wallet so they are ready for use." This statement is not correct and should not be included in the teaching plan. Storing condoms in a wallet can damage them by exposing them to heat, friction, or puncture. Damaged condoms can break or leak during sexual activity and increase the risk of STIs or pregnancy.
Choice B: "Use petroleum jelly with a latex condom for extra lubrication." This statement is not correct and should not be included in the teaching plan. Using petroleum jelly or any oil-based lubricant with a latex condom can weaken the latex material and cause it to break or slip off. Only water-based or silicone-based lubricants should be used with latex condoms.
Choice C: "Put the condom on before engaging in any genital contact." This statement is correct and should be included in the teaching plan. Putting the condom on before engaging in any genital contact can prevent the transmission of STIs or pregnancy by avoiding contact with pre-ejaculate fluid, semen, or vaginal fluid.
Choice D: "You can reuse a condom if it's within 3 hours." This statement is not correct and should not be included in the teaching plan. Reusing a condom can increase the risk of STIs or pregnancy by exposing the partner to residual fluid, bacteria, or sperm. A new condom should be used for each sexual act.
Correct Answer is D
Explanation
Choice A: A 26-year-old client who has migraine headaches at the start of each menstrual cycle is not the correct answer because they do not have a contraindication for receiving oral contraceptives. Oral contraceptives are pills that contain synthetic hormones (estrogen and progestin) that prevent ovulation and pregnancy. They can also help reduce menstrual cramps, bleeding, and migraines in some women. However, oral contraceptives may increase the risk of stroke in women who have migraines with aura (visual disturbances), so they should be used with caution and under medical supervision.
Choice B: A 28-year-old client who has a history of pelvic inflammatory disease is not the correct answer because they do not have a contraindication for receiving oral contraceptives. Pelvic inflammatory disease is an infection that affects the female reproductive organs, such as the uterus, fallopian tubes, or ovaries. It can be caused by various bacteria, such as chlamydia or gonorrhea, and can lead to infertility, ectopic pregnancy, or chronic pelvic pain if left untreated. Oral contraceptives can help prevent pelvic inflammatory disease by creating a thick cervical mucus that blocks the entry of bacteria into the uterus.
Choice C: A 32-year-old client who has benign breast disease is not the correct answer because they do not have a contraindication for receiving oral contraceptives. Benign breast disease is a term that refers to various noncancerous conditions that affect the breast tissue, such as fibrocystic changes, fibroadenomas, or mastitis. They can cause symptoms such as breast pain, tenderness, or lumps. Oral contraceptives can help reduce the symptoms of benign breast disease by regulating the hormonal fluctuations that influence breast tissue growth.
Choice D: A 38-year-old client who reports smoking one pack of cigarettes every day is the correct answer because they have a contraindication for receiving oral contraceptives. Smoking is a habit that involves inhaling tobacco smoke, which contains harmful substances such as nicotine, tar, or carbon monoxide. Smoking can increase the risk of various diseases such as lung cancer, chronic obstructive pulmonary disease (COPD), or cardiovascular disease. Oral contraceptives can further increase the risk of cardiovascular disease in smokers, especially those who are over 35 years old, by increasing blood pressure, cholesterol levels, and clotting factors. Therefore, oral contraceptives are not recommended for smokers and alternative methods of contraception should be used instead.
