A nurse is reinforcing teaching about saturated fats with a client who is at risk for cardiovascular disease. Which of the following cooking fats should the nurse recommend the client use?

Choice A reason: BUN or blood urea nitrogen 30 mg/dL is above the normal range of 10 to 20 mg/dL and indicates renal impairment or dehydration, which can be caused by contrast dye used during coronary angiography or blood loss during or after the procedure. The nurse should report this value to the provider and monitor the client for signs of acute kidney injury, such as oliguria, edema, or electrolyte imbalances.

Choice B reason: Sinus rhythm 95/min on a cardiac monitor is within the normal range of 60 to 100/min and does not indicate any cardiac arrhythmia or ischemia.

Choice C reason: Respiratory rate 12/min is within the normal range of 12 to 20/min and does not indicate any respiratory distress or hypoxia.

Choice D reason: PTT or partial thromboplastin time 25 seconds is within the normal range of 25 to 35 seconds and does not indicate any bleeding disorder or anticoagulant therapy.

Choice A: This is incorrect because placing the client in the Sims' position is not necessary for a colposcopy. The nurse should place the client in the lithotomy position, which allows better visualization of the cervix and vagina.

Choice B: This is incorrect because inserting a tampon following the procedure can interfere with healing and increase the risk of infection. The nurse should instruct the client to avoid using tampons, douches, or vaginal creams for at least a week after the procedure.

Choice C: This is correct because instructing the client to avoid sexual intercourse until the cervix is healed can prevent bleeding, infection, and trauma to the cervix. The nurse should advise the client to abstain from sexual activity for at least a week or until advised by the provider.

Choice D: This is incorrect because reinforcing teaching that the procedure involves dilation of the cervix can cause anxiety and discomfort for the client. The nurse should explain that the procedure does not require dilation of the cervix, but rather involves applying a speculum and using a microscope to examine the cervix and take tissue samples if needed.
