Correct Answer: B

Rationale: Monitoring oxygen saturation levels is the most important intervention in this scenario. It ensures that the client is receiving adequate oxygenation, which is crucial for a client with pneumonia. By monitoring saturation levels, the nurse can promptly identify any oxygenation issues and adjust the oxygen delivery if necessary. Encouraging fluid intake, changing oxygen tubing daily, and assisting with frequent position changes are also important aspects of care for a client with pneumonia, but they are not as critical as monitoring oxygen saturation levels in ensuring immediate respiratory support.

Correct Answer: C

Rationale: The correct answer is C: 'I may experience difficulty sleeping while taking this medication.' Sertraline can cause insomnia, especially when first starting the medication, so the client should be aware of this potential side effect. Choices A, B, and D are incorrect because feeling better immediately, increased urination, and decreasing sodium intake are not commonly associated side effects of sertraline.

Correct Answer: C

Rationale: Corrected Rationale: Poor problem-solving ability is a common cognitive symptom of schizophrenia. It affects the client's ability to think clearly and make decisions. Decreased level of consciousness (Choice A) is not a typical assessment finding in schizophrenia. Inability to identify common objects (Choice B) is more indicative of conditions like dementia. Preoccupation with somatic disturbances (Choice D) is characteristic of somatic symptom disorders, not schizophrenia.

Correct Answer: A

Rationale: Web-based applications are the most effective strategy for reaching young adults in the target group regarding safe sexual practices. Young adults today are highly engaged with mobile technology and the internet, making web-based applications the most accessible and convenient method to disseminate information. Print-based media like newspapers may not have the same reach and engagement among young adults. Television advertisements might reach a broader audience, but they may not be as targeted to the specific demographic of young adults. Brochures in kiosks in malls are less likely to reach a large number of young adults compared to web-based applications, which can be accessed anytime and anywhere through mobile devices.

Correct Answer: B

Rationale: The correct answer is B: 'Take with a glass of orange juice.' Ferrous sulfate should be taken with orange juice (vitamin C) to enhance the absorption of iron. Taking it with milk (choice A) is not recommended as calcium can interfere with iron absorption. Taking it at bedtime (choice C) or with meals (choice D) may lead to decreased absorption due to interactions with other food or medications.
