Which of the following locations provides the most accurate measurement of actual body temperature?
Rectal
Axillary
Oral
Temporal
The Correct Answer is A
A. Rectal: Rectal temperature measurement provides core body temperature and is considered the most accurate reflection of internal body heat. It is less influenced by environmental factors and provides reliable readings for clinical assessment.
B. Axillary: Axillary temperature is taken under the arm and tends to be lower than core temperature. It is easy and noninvasive but less accurate due to heat loss to the environment and variations in placement.
C. Oral: Oral temperature is convenient and reasonably accurate in cooperative patients but can be affected by recent food or fluid intake, mouth breathing, or smoking. It does not always reflect true core temperature.
D. Temporal: Temporal artery thermometry is noninvasive and quick but can be influenced by sweating, ambient temperature, and improper technique, making it slightly less precise than rectal measurement for core temperature.

Correct Answer is A
Explanation
The Teach-Back Method asks the patient to restate information in their own words, allowing the healthcare provider to assess comprehension, identify misunderstandings, and clarify information immediately. It is an evidence-based communication strategy commonly used in patient education and counseling sessions to improve adherence and outcomes.
Correct Answer is C
Explanation
A. Lower risk of hospitalizations: Traumatic falls in adults ≥65 years are associated with higher rates of emergency visits, hospital admissions, and complications such as fractures and head injuries, rather than a reduced hospitalization risk.
B. Increased medication use: Although medication use may increase after a fall due to pain management or new diagnoses, this is a consequence of injury management and comorbidities, not a complication syndrome directly resulting from the fall event itself.
C. Development of “Post-Fall Anxiety” Syndrome: Older adults commonly develop fear of falling after a traumatic fall, leading to anxiety, reduced mobility, activity avoidance, and loss of independence, which can further increase fall risk and functional decline.
D. Decreased nursing home admissions: Falls in older adults increase the likelihood of functional impairment, disability, and need for long-term care placement, making decreased nursing home admissions inconsistent with known outcomes.
