Rationale: Before rigor mortis occurs, it is essential to place a pillow under the body's head and shoulders to maintain proper positioning. This helps prevent postmortem changes and ensures a more dignified appearance. Providing a complete bath and dressing change, removing clothing, or wrapping the body in a shroud are tasks typically done after rigor mortis sets in or later in the postmortem care process. Allowing the body to relax normally does not address the need for proper positioning before rigor mortis occurs.

Correct Answer: B

Rationale: Acute illnesses are characterized by the sudden onset of severe symptoms that typically last for a short duration. These conditions usually resolve within a defined period, unlike chronic illnesses that persist over a longer time frame. Pain and syndrome are not specific types of illnesses but rather symptoms or clinical manifestations that can occur in various health conditions.

Rationale: In cases where the oral route is not recommended due to oral surgery or altered consciousness, the rectal method is preferred for the most accurate body temperature reading. This method is particularly useful when the skin is flushed and warm, as it provides a reliable reflection of core body temperature despite external factors affecting the skin temperature. Axillary temperature may not be as accurate, and arterial line temperature monitoring is invasive and not typically used for routine temperature assessment.

Correct Answer: B

Rationale: The nursing process is a systematic, rational method that guides nurses in planning and delivering patient care. It involves a series of steps including assessment, diagnosis, planning, implementation, and evaluation. By utilizing the nursing process, nurses can provide individualized care tailored to the specific needs of patients, families, groups, and communities.
