RN Nursing Care of Children Online Practice 2019 A

Correct Answer: C

Rationale: The correct answer is C: RSV, influenza, and adenovirus. The CDC recommends respiratory hygiene and etiquette to prevent the transmission of respiratory syncytial virus (RSV), influenza, adenovirus, and other droplet-transmitted unknown viruses. Choices A, B, and D are incorrect because HBV, Hib, pertussis, HSV, and varicella are not typically transmitted via droplets but through other modes of transmission.

Correct Answer: A

Rationale: The correct answer is A. The use of placebos without the patient's consent is unethical and goes against the principles of beneficence and autonomy. Choice B is incorrect because using placebos does not provide reliable information about the presence or severity of the pain; it only indicates the response to the placebo itself. Choice C is wrong as the absence of a response to a placebo does not definitively mean that the child's pain has an organic basis; there could be various reasons for the lack of response. Choice D is also incorrect as individuals may have a positive response to a placebo even if their pain has a significant organic cause. Therefore, the most appropriate response is A, emphasizing the ethical concerns surrounding the use of placebos without informed consent.

Correct Answer: D

Rationale: The correct answer is D: Hypertension. Nephroblastoma, also known as Wilms' tumor, often causes hypertension due to its impact on the kidney, which plays a role in regulating blood pressure. Atrial fibrillation (choice A) and endocarditis (choice B) are not typically associated with nephroblastoma. Hyperlipidemia (choice C) is also not a common clinical manifestation of nephroblastoma.

Correct Answer: C

Rationale: Aspirating urine from cotton balls inside the diaper is a minimally invasive method and effective for collecting small amounts of urine. Using a collection bag can be more cumbersome, and other methods are not as effective for this age.

Correct Answer: C

Rationale: Eye drops should be placed in the conjunctival sac, which allows the medication to be absorbed properly without causing irritation. Placing drops directly on the sclera or near the lacrimal duct is less effective and can cause discomfort.
