What is one sign of pneumonia?

Correct Answer: B

Rationale: The correct answer is B: Chest pain when inhaling. This is because chest pain when inhaling, known as pleuritic chest pain, is a common symptom of pneumonia due to inflammation of the lining around the lungs. This pain worsens with deep breaths or coughing. Low-grade fever (A) is a common symptom of pneumonia, but it is not a specific sign as it can be present in many other conditions. Decreased pulse (C) is not a typical sign of pneumonia, as the body usually increases the heart rate in response to infection. Cyanosis (D), which is a bluish discoloration of the skin due to lack of oxygen, can occur in severe cases of pneumonia but is not an early sign.

Correct Answer: D

Rationale: The correct answer is D because an opportunistic infection is an illness caused by microorganisms that typically do not cause disease in individuals with healthy immune systems but can lead to infections in people with weakened immune systems. This occurs because the weakened immune system is unable to effectively defend against these microorganisms. Choice A is incorrect because it describes abnormal cell growth, which is not the definition of an opportunistic infection. Choice B is incorrect as it refers to the temporary disappearance of cancer symptoms, not related to opportunistic infections. Choice C is also incorrect as it describes a specific disorder related to bladder inflammation, not opportunistic infections.

Correct Answer: C

Rationale: The correct answer is C: Extension. Extension refers to the straightening of a body part, such as extending the arm or leg. Flexion (A) is the bending of a body part. Pronation (B) refers to the downward rotation of the forearm. Adduction (D) is the movement of a body part towards the midline. In this case, extension is the most appropriate term as it specifically describes the action of straightening a body part, making it the correct answer.

Correct Answer: A

Rationale: The correct answer is A: Cremation. Cremation is the process of burning a dead body until it turns to ash. This is done in a specialized furnace called a crematorium. Libation (B) is a ritual pouring of a liquid as an offering to a deity. Pronation (C) is the act of lying face down. Expiration (D) refers to the act of breathing out or the ending of something, not the process of burning a body. In summary, cremation is the only choice that accurately describes the process of burning a dead body to ash.
