Correct Answer: A

Rationale: The correct answer is A. Secondary prevention aims to detect and address health issues early. Screening older adults in nursing care facilities for early influenza manifestations is an example of secondary prevention by identifying cases at an early stage. Choice B, promoting hand hygiene, is a form of primary prevention that aims to prevent the occurrence of influenza. Choice C, administering influenza vaccinations, is a form of primary prevention as well, focusing on preventing the disease before it occurs. Choice D, educating about healthy lifestyle choices, is more related to health promotion and primary prevention rather than secondary prevention.

Correct Answer: A

Rationale: Gas pains in the periumbilical area postoperatively are often caused by impaired peristalsis and bowel function. Following abdominal surgery, it is common for peristalsis to be reduced due to surgical manipulation and anesthesia effects. This reduction in peristalsis can lead to the accumulation of gas in the intestines, resulting in gas pains. Infection at the surgical site (Choice B) would present with localized signs of infection such as redness, swelling, warmth, and drainage, rather than diffuse gas pains. Fluid overload (Choice C) would manifest with symptoms such as edema, increased blood pressure, and respiratory distress, not gas pains. Inadequate pain management (Choice D) may lead to increased discomfort, but it is not the primary cause of gas pains in the periumbilical area following a small bowel resection.

Correct Answer: B

Rationale: The ventrogluteal site is the most appropriate and safest site for administering an intramuscular injection to an adult client. It is preferred due to its thick muscle mass and fewer major blood vessels and nerves in the area, reducing the risk of injury or complications. The deltoid muscle is commonly used for vaccines and small-volume injections but may not be suitable for larger volumes. The dorsogluteal site has fallen out of favor due to the risk of injury to the sciatic nerve and other underlying structures. The rectus femoris site is not typically used for intramuscular injections in adults.

Correct Answer: C

Rationale: The correct answer is a partial bed bath (Choice C). A partial bed bath involves washing body parts that the patient cannot reach on their own, such as the back. It also includes providing assistance with a backrub to promote circulation and skin integrity. In this scenario, where the patient is bedridden and unable to reach all body parts, a partial bed bath is the most appropriate as it focuses on areas the patient cannot clean themselves. Choices A, B, and D are incorrect because a bag bath involves using premoistened disposable cloths for bathing, a sponge bath involves using a basin of water and a sponge for cleansing, and a complete bed bath involves washing the entire body, including areas the patient can reach, which are not necessary in this case.

Correct Answer: B

Rationale: In the scenario described, the client is experiencing symptoms of an anaphylactic reaction, a severe allergic response. The priority action in an anaphylactic reaction is to administer epinephrine. Epinephrine helps counteract the severe allergic response, improves breathing difficulties, and maintains airway and circulation. Administering epinephrine takes precedence to stabilize the client's condition. Options A, C, and D may be necessary in the management of anaphylaxis, but the immediate priority is to administer epinephrine to address the life-threatening symptoms.
