Correct Answer: C

Rationale: During peak influenza season, older clients should take measures to reduce the risk of contracting the flu. The most effective preventive measure is frequent hand hygiene and refraining from touching the face, as this reduces the transmission of the flu virus. While it is advisable to avoid crowds, the direct action of hand hygiene is more impactful. Doing errands early in the morning when crowds are smaller is a good suggestion to reduce exposure but does not address the direct transmission through hands. Drinking enough fluid daily is important for overall health but does not directly reduce the risk of contracting influenza.

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: The correct answer is that using a condom during intercourse can reduce the risk of STI transmission. Abstinence is a way to prevent STIs, but not the only way. Using a spermicide along with a condom can help prevent pregnancy, not STIs. While condoms may fail to prevent pregnancy, they are effective in reducing the risk of STI transmission. Therefore, using a latex condom for pregnancy prevention is not directly related to preventing the transmission of STIs.

Correct Answer: B

Rationale: When auscultating the fetal heart rate, the nurse would place the fetoscope on the maternal abdomen, over the fetal back. The nurse would then palpate the mother's radial pulse. If her pulse is synchronized with the sounds from the fetoscope, the nurse would move the fetoscope to another area on the mother's abdomen to locate the FHR. The nurse needs to be sure that the FHR is what is actually being heard. Other sounds that may be heard are the funic sound (blood flowing through the umbilical cord) and the uterine sound (blood flowing through the uterine vessels). The funic sound is synchronized with the FHR; the uterine sound is synchronized with the mother's pulse. Therefore, moving the fetoscope to a different area will help in accurately locating and counting the fetal heart rate. Choice A is incorrect because counting for 60 seconds without changing the position may not address the issue of accurately locating the FHR. Choice C is incorrect as it does not address the need to reposition the fetoscope to locate the fetal heart. Choice D is incorrect because counting the FHR and the radial pulse rate separately may not help in differentiating the two sounds.

Correct Answer: D

Rationale: When a nurse observes senile tremors, such as intentional tremor of the hands in a client in later adulthood, it is important to document the findings. Senile tremors are benign and a normal age-related occurrence. Referring the client to a neurological specialist (Choice A) is unnecessary as senile tremors do not require specialized neurological intervention. Prescribing a muscle relaxant (Choice B) is not indicated since senile tremors are benign and not typically treated with muscle relaxants. Notifying the healthcare provider immediately (Choice C) is unnecessary as senile tremors do not require urgent intervention. Therefore, the most appropriate action is to document the findings (Choice D) for the client's medical record and to establish a baseline for future assessments.
