Correct Answer: D

Rationale: The correct answer is D: Positive ASO titer. A positive ASO titer indicates recent streptococcal infection, which is associated with acute rheumatic fever. Thrombocytopenia (choice A) is not a typical laboratory finding in acute rheumatic fever. Polycythemia (choice B) refers to an increased red blood cell count, which is not typically seen in acute rheumatic fever. Decreased ESR (choice C) is not a common laboratory finding in acute rheumatic fever; in fact, ESR is often elevated in inflammatory conditions like rheumatic fever.

Correct Answer: C

Rationale: The correct answer is C because it provides a truthful yet sensitive response to the child's question. Saying that the body will stop functioning and that there will be no more pain helps the child understand what to expect without unnecessary details or causing distress. Choice A is too technical and may not be suitable for a child. Choice B might give the impression of a peaceful passing, which may not always be the case. Choice D introduces the concept of feeling tired, which might not be accurate or helpful in this context.

Correct Answer: A

Rationale: The most important instruction for a client receiving risedronate sodium to treat osteoporosis is to remain upright for 30 minutes after taking the medication. Risedronate sodium can cause esophageal irritation, and staying upright helps prevent this side effect. While increasing vitamin D intake, starting a low-impact exercise routine, and taking the medication with a full glass of water are all beneficial for managing osteoporosis, the immediate need is to prevent esophageal irritation caused by risedronate sodium.

Correct Answer: A

Rationale: The correct answer is option A because this client is the most stable and requires less supervision. Assigning a client whose discharge has been delayed due to a postoperative infection to the newly graduate practical nurse would be appropriate during a busy day as they are likely to need routine care and monitoring rather than immediate intensive interventions. Option B involves a client with poorly controlled type 2 diabetes on a sliding scale for insulin administration, which requires close monitoring and prompt intervention, making it a less suitable assignment for a new graduate who may need more guidance. Option C, a newly admitted patient with a head injury requiring frequent assessments, would demand a higher level of vigilance and expertise, which may be challenging for a new graduate nurse to handle without adequate supervision. Option D, a patient receiving IV heparin regulated based on protocol, involves complex medication management that may be too advanced for a new graduate nurse without sufficient oversight.

Correct Answer: A

Rationale: The correct instruction for the adult male client to follow when collecting a 24-hour urine specimen for a creatinine clearance test is to urinate at the specified time, discard this urine, and collect all subsequent urine over the next 24 hours. This method ensures proper collection for an accurate creatinine clearance measurement. Choice B is incorrect as it describes a different procedure for a clean-catch urine sample, not suitable for creatinine clearance. Choice C is incorrect as it suggests catheterization, which is not typically done for a creatinine clearance test, and it is not necessary for this procedure. Choice D is incorrect as it does not follow the standard procedure for a 24-hour urine collection for creatinine clearance; the urine should be collected continuously over 24 hours, not at specified intervals.
