Correct Answer: A

Rationale: For a 5-year-old child, dental examinations should be conducted every 6 months. This frequency allows for early detection of dental issues and promotes good oral health. Choices B, C, and D are incorrect because waiting for a new primary tooth to erupt, having an examination once a year, or every 3 months are not the recommended intervals for dental check-ups in this age group. It is essential to adhere to the standard guideline of every 6 months to ensure regular monitoring and preventive care for the child's dental health.

Correct Answer: B

Rationale: The correct question the nurse should ask to identify risk factors associated with the use of an oral contraceptive is whether the client smokes cigarettes. Oral contraceptives are associated with an increased risk of thromboembolic phenomena, particularly when combined with other risk factors like smoking and a history of thrombosis. Other risk factors include hypertension, cerebrovascular disease, coronary artery disease, and postoperative thrombosis risk. Choices A, C, and D are not directly related to the increased risks associated with oral contraceptive use. Menstrual cramps, dieting, and strenuous exercise are not significant risk factors for thromboembolic events.

Correct Answer: C

Rationale: The correct advantage of using CVADs for chemotherapeutic agent administration is that chemotherapeutic agents can be caustic to smaller veins. Many chemotherapeutic drugs are vesicants, which can cause tissue damage even in low concentrations. Using a CVAD to administer these agents into a large vein is optimal as it reduces the risk of damage. Choice A is incorrect as CVADs are actually more expensive than a peripheral IV, making it a disadvantage. Choice B is incorrect because the frequency of administration depends on the specific drug being administered, not on the access device, so it does not represent a universal advantage. Choice D is incorrect because IV chemotherapeutic agents are typically not self-administered at home; they are usually given in a hospital, outpatient, or clinic setting, making it an invalid advantage of using CVADs.

Correct Answer: D

Rationale: Individuals living in poverty often face barriers to accessing regular healthcare services, leading them to utilize Emergency Departments or urgent care centers as their primary source of healthcare. These facilities provide immediate care without the need for appointments or insurance, making them more accessible to those in poverty. While primary care physicians and neighborhood clinics are essential for preventive care, individuals in poverty may have difficulty accessing these services due to financial constraints or lack of insurance. Specialists typically require referrals and may not be easily accessible to individuals without stable healthcare coverage. Therefore, Emergency Departments or urgent care centers are the most likely healthcare option for people living in poverty.

Correct Answer: A

Rationale: The nurse would use the Leopold maneuvers to identify the position of the fetus and determine the location of the fetal back. The fetal heart rate (FHR) is most easily heard through the fetal back because it usually lies closest to the surface of the maternal abdomen. Auscultation of the FHR over the chest, carotid artery, or brachial area is not possible due to the fetal position within the maternal abdomen. Placing the fetoscope over the carotid artery or brachial area would not yield the fetal heart rate, and the chest area is not typically used for auscultating the FHR.
