A child weighing 55 lb has been prescribed cefotaxime at a dosage of 150 mg/kg/day, to be administered in divided doses every 6 hours.

How many mg should the nurse administer each day? (Provide a numerical value only.)

Choice A rationale

Counting and recording the number of premature ventricular contractions per minute is not the immediate priority for a patient experiencing symptoms of angina and shortness of breath. While it is important to monitor the patient’s heart rhythm, the immediate priority is to address the patient’s symptoms and stabilize their condition.

Choice B rationale

Applying oxygen via a nasal cannula and adjusting to maintain oxygen saturation above 93% is the immediate priority for a patient experiencing symptoms of angina and shortness of breath. Oxygen therapy can help to relieve the symptoms of angina and improve the patient’s oxygen saturation.

Choice C rationale

Ensuring troponin level assessments are scheduled every 3 to 6 hours for a series of three is important for diagnosing a heart attack, but it is not the immediate priority. The immediate priority is to address the patient’s symptoms and stabilize their condition.

Choice D rationale

Initiating dim lighting, lowering alarm volumes, and controlling traffic in and out of the room area can help to create a calm and quiet environment for the patient. However, this is not the immediate priority. The immediate priority is to address the patient’s symptoms and stabilize their condition.

Choice A rationale

While it’s true that many contraceptives can help prevent certain sexually transmitted infections (STIs), they are not 100% effective. Condoms, for instance, can reduce the risk of STIs that are spread through bodily fluids, such as gonorrhea and chlamydia. However, they are less effective at protecting against STIs that are transmitted through skin-to-skin contact, such as herpes and human papillomavirus (HPV)1.

Choice B rationale

Not all STIs are transmitted through sexual intercourse. Some STIs, such as herpes and HPV, can be spread through skin-to-skin contact. Others, like HIV and hepatitis B and C, can also be spread through sharing needles or from mother to child during childbirth.

Choice C rationale

Safe sex practices can significantly reduce, but not completely remove, the risk of STIs. These practices include using condoms correctly every time you have sex, getting tested regularly for STIs, and limiting the number of sexual partners.

Choice D rationale

Reinfections can indeed occur from having sex with untreated partners. This is particularly true for bacterial STIs like syphilis. If a person’s partner is not treated, the bacteria can remain in their body and they can pass the infection back to the person after they’ve been treated.
