Correct Answer: B

Rationale: In order to understand and interpret a message accurately, it is essential to consider the context in which it was delivered. Context provides the necessary background information, setting, and circumstances that give meaning and relevance to the message being communicated. Without context, it can be challenging to fully grasp the intention and significance of the communication. While the other options (process, phrases and sentences, thoughts and feelings) play roles in communication, it is the context that ultimately helps to give meaning and context to the message being conveyed.

Correct Answer: A

Rationale: Multiple myeloma is a type of cancer that develops in plasma cells, which are a type of white blood cells involved in the body's immune response. As a result, multiple myeloma primarily affects the hematologic system, which includes the blood and blood-forming tissues. This cancer typically arises in the bone marrow and can lead to an overproduction of abnormal plasma cells, which can crowd out healthy blood cells. Symptoms of multiple myeloma can include anemia, bone pain, recurrent infections, fatigue, and kidney problems, all of which are related to the hematologic system.

Correct Answer: D

Rationale: The planning function of Nurse Ellen in her role as a nurse manager best corresponds to option D, which is to determine how to achieve the mandate of work. Planning involves setting objectives, developing strategies, and outlining the steps to accomplish those objectives. As a nurse manager, Nurse Ellen would be responsible for creating plans to ensure the effective delivery of patient care, efficient allocation of resources, and meeting the organizational goals of the unit. By determining how to achieve the work mandate, Nurse Ellen can effectively lead her team, allocate resources efficiently, and navigate any challenges that may arise in the operation of the nursing unit.

Correct Answer: C

Rationale: The diagnosis of contact latex allergy is primarily based on the patient's history of exposure to latex-containing products and the development of symptoms upon contact with latex. To confirm the diagnosis, skin patch testing is performed. Skin patch testing exposes the skin to small amounts of latex allergens to observe for any localized allergic reaction, such as redness, swelling, or itchiness. This test helps determine if the individual has developed a delayed-type hypersensitivity reaction to latex. Latex-specific IgE testing (choice A) and finding IgE in serum (choice B) are methods used in diagnosing immediate-type latex allergy but are not sufficient for confirming contact latex allergy specifically. ELISA (choice D) is a type of laboratory technique used for various purposes, including measuring the levels of specific substances in the blood, but it is not typically used as a diagnostic tool for contact latex allergy.

Correct Answer: B

Rationale: The correct information for the nurse to include in patient education about aspirin therapy is to advise the patient to avoid using nonsteroidal anti-inflammatory drugs (NSAIDs) while taking aspirin. NSAIDs can increase the risk of gastrointestinal bleeding when taken along with aspirin, which is already a blood-thinning medication due to its antiplatelet effects. Patients with coronary artery disease are typically prescribed aspirin for its antiplatelet properties to prevent blood clot formation in the arteries. Avoiding NSAIDs will help reduce the risk of gastrointestinal complications and ensure the effectiveness of aspirin therapy in preventing cardiovascular events. Taking aspirin with a full glass of milk (Option A) is not a necessary instruction for aspirin therapy. Discontinuing aspirin therapy if a patient develops a fever (Option C) is not a standard practice unless advised by a healthcare provider. Taking aspir
