Correct Answer: D

Rationale: A focused assessment is more in-depth on specific issues, providing detailed information on a particular problem or concern. This allows for targeted interventions and treatment strategies. In contrast, a comprehensive assessment covers the body head to toe and involves all body systems, which may not be necessary when focusing on a specific issue. Occurring only in the clinic is a limitation to choice B, as assessments can be conducted in various settings. Involving all body systems, as stated in choice C, is not the primary focus of a focused assessment.

Correct Answer: A

Rationale: The proper hand position for chest percussion is to cup the hands, creating a hollow space to allow for effective transmission of percussion vibrations. Cupping the hands helps to produce the desired percussion sound and ensures proper force distribution. Using the side of the hands (B) may not provide enough surface area for effective percussion. Flattening the hands (C) may not generate the desired percussive effect, and spreading the fingers of both hands (D) can result in uneven force application. Therefore, cupping the hands is the most appropriate hand position for chest percussion.

Correct Answer: A

Rationale: The correct answer is A: Administer epinephrine. Epinephrine is the first-line treatment for anaphylaxis as it helps to quickly reverse severe symptoms by constricting blood vessels and opening airways. Administering corticosteroids (B) is not the immediate priority. Placing the client on their side (C) is important to prevent aspiration but does not address the anaphylactic reaction. Monitoring blood pressure (D) is essential but administering epinephrine takes precedence in managing anaphylaxis.

Correct Answer: B

Rationale: The correct answer is B: Tenderness, warmth, and swelling at the site. Post-operative wound infection often presents with localized tenderness, warmth, and swelling due to inflammation and immune response. Redness, heat, and purulent drainage (choice A) can also indicate infection but are not specific to wound infections. Excessive swelling and redness (choice C) may be present in inflammatory responses but do not specifically point to an infection. Fever, chills, and nausea (choice D) can be systemic signs of infection but are not specific to wound infections. Tenderness, warmth, and swelling are more indicative of a localized wound infection.

Correct Answer: A

Rationale: The nurse should first administer aspirin to a client with chest pain as it helps prevent blood clot formation during a possible heart attack. Aspirin inhibits platelet aggregation, reducing the risk of further blockage in the coronary arteries. Administering aspirin promptly can improve the client's outcomes. Performing an ECG, monitoring vital signs, or providing a meal plan are important but should come after administering aspirin in the initial management of chest pain to prioritize the client's safety and well-being.
