Which of the following organisms is responsible for the development of rheumatic fever?

Correct Answer: C

Rationale: Rheumatic fever is an inflammatory disease that can develop after an untreated or inadequately treated infection with group Aß-hemolytic streptococcus bacteria, particularly Streptococcus pyogenes. This bacteria causes strep throat, which if left untreated, can lead to complications such as rheumatic fever. Rheumatic fever primarily affects the heart, joints, skin, and brain. It is important to promptly treat streptococcal infections with antibiotics to prevent the development of rheumatic fever.

Correct Answer: C

Rationale: It is important to instruct the client's family to check with the physician or pharmacist before crushing or breaking tablets, or opening capsules for a client with impaired swallowing who needs to take solid medication. Many medications have special formulations or coating that may alter their effectiveness if not taken whole. Consulting with a healthcare professional ensures that the medication remains safe and effective when modifying its form for a client with difficulty swallowing. Mixing the medication with food (option A) may also alter its effectiveness, so it is crucial to seek guidance before making any changes to the medication form. Using the liquid form of the medication (option B) may be a suitable alternative if available; however, this decision should also be discussed and approved by the healthcare provider. Performing ROM exercises after medication administration (option D) is unrelated to addressing the issue of impaired swallowing and medication administration.

Correct Answer: C

Rationale: Wilms tumor typically occurs in children aged 2-5 years and may be associated with congenital anomalies. It is not the same as neuroblastoma, and its prognosis is generally good with treatment.

Correct Answer: A

Rationale: Respiratory acidosis is indicated by a low pH and elevated PCO2, as seen in option A.

Correct Answer: B

Rationale: Chorea is the result of central nervous system manifestations. Chorea is a movement disorder characterized by involuntary, brief, random, and irregular muscle movements that are often seen in neurological conditions such as Huntington's disease. The central nervous system is responsible for controlling and coordinating movements, so any dysfunction in the central nervous system can lead to movement disorders like chorea. Therefore, chorea is directly related to central nervous system manifestations, unlike congestive heart failure, valve damage, or pericarditis which are primarily related to cardiovascular issues.
