Correct Answer: B

Rationale: Assessing for signs of infection at the insertion site is the priority when caring for a client with a chest tube. Infection at the insertion site can lead to serious complications such as empyema or sepsis. Monitoring respiratory status is essential but assessing for infection takes precedence to prevent immediate harm. Assessing for subcutaneous emphysema is important but not the priority unless it compromises respiratory function. Checking the chest tube for kinks or occlusions is crucial for proper drainage but is not the priority when infection is a concern.

Correct Answer: B

Rationale: The correct answer is B because a positive acid-fast bacillus smear in an elderly factory worker suggests tuberculosis, a serious communicable disease that must be reported promptly to the public health department to prevent its spread. Choice A is incorrect as Shigella is an important pathogen, but it does not require immediate public health reporting. Choice C is incorrect because Pneumocystis carinii is an opportunistic pathogen and does not require urgent public health reporting. Choice D is incorrect as varicella-zoster virus causes chickenpox and shingles, both of which are not reportable diseases to the public health department.

Correct Answer: D

Rationale: The correct answer is D. Deep injection helps to prevent tissue irritation caused by iron, which can be damaging to tissues. Option A is incorrect because deep injection does not primarily aim to enhance absorption, but rather to prevent tissue irritation. Option B is incorrect as the route of administration does not determine whether the entire dose is given. Option C is incorrect because the even distribution of the drug is not the main purpose of deep injection in this context.

Correct Answer: B

Rationale: Coughing up foul-tasting, brown, thick sputum suggests a possible abscess or secondary infection, requiring attention. Choice A may indicate pleurisy, but the focus should be on the sputum. Choice C may be non-specific and could be related to the infection or fever. Choice D is non-specific and may be expected during an infection.
