Correct Answer: A

Rationale: A respiratory rate of 20 breaths per minute indicates effective oxygen therapy. In pneumonia, the respiratory rate typically increases due to the body's effort to improve oxygenation. Option B (pH of 7.35) is related to acid-base balance, not specifically indicating oxygen therapy effectiveness. Option C (oxygen saturation of 92%) is below the normal range (95-100%), suggesting the need for oxygen therapy. Option D (clear breath sounds) is a positive finding but not a direct indicator of oxygen therapy effectiveness.

Rationale: Screening for visual acuity helps identify children who may need corrective lenses or other interventions.

Correct Answer: D

Rationale: The correct answer is 'D.' The client stating 'I may experience some neck swelling' does not indicate a need for further teaching since neck swelling is an expected side effect of radioactive iodine therapy. Choices A and B are correct statements as the client should avoid close contact with pregnant women and children for a few days due to radiation exposure, and dry mouth and taste changes are common side effects. Choice C is redundant with choice D, making D the correct answer.

Correct Answer: C

Rationale: Administering the medication with a small amount of pudding helps prevent aspiration in clients with dysphagia.

Correct Answer: B

Rationale: The correct answer is 'B: influenza.' Influenza vaccination is crucial for adults, particularly in rural areas where access to healthcare may be limited. Influenza can cause serious illness and complications, and vaccination helps protect individuals and prevent the spread of the virus. While vaccines for hepatitis A, varicella, and measles, mumps, rubella (MMR) are important, prioritizing influenza vaccination in this scenario is essential due to its seasonal prevalence and potential impact on public health.
