What is the body mass index (BMI) of a person who is considered overweight?

Correct Answer: C

Rationale: The correct answer is C (25 to 29) for a person considered overweight based on BMI. A BMI of 25 to 29 falls within the overweight range as defined by the World Health Organization. This range indicates an increased risk of health issues associated with excess weight. Choices A (30 to 39) and B (40 or higher) represent obesity categories, not just overweight. Choice D (20 to 25) is in the healthy weight range. Therefore, the correct answer is C.

Correct Answer: D

Rationale: The correct answer is D: 5 to 8 minutes. After applying the specimen to the test area, waiting 5 to 8 minutes allows adequate time for the chemical reaction to occur and for the results to develop accurately. Waiting too short of a time may lead to a false negative result, while waiting too long may result in a false positive. Options A, B, and C are incorrect as they do not allow sufficient time for the test to develop accurately, leading to potential inaccurate results and misinterpretation of the test outcome.

Correct Answer: D

Rationale: The correct answer is D: Benign prostatic hypertrophy (BPH). BPH is a non-cancerous enlargement of the prostate gland, leading to urinary symptoms. The prostate gland surrounds the urethra, and when enlarged, it can obstruct urine flow. Genital herpes (A) is a sexually transmitted infection causing painful sores, not prostate enlargement. Erectile dysfunction (B) is the inability to achieve or maintain an erection, unrelated to prostate enlargement. Prostate cancer (C) is a malignant growth in the prostate gland, different from the non-cancerous enlargement seen in BPH.

Correct Answer: A

Rationale: The correct answer is A: Contusion. A contusion is a type of closed wound caused by blunt force trauma, resulting in damaged blood vessels and surrounding tissues without breaking the skin. This is different from the other choices: B) Puncture, which involves penetration of the skin by a sharp object, C) Incision, which is a deliberate cut made by a sharp object, and D) Laceration, which is a jagged or irregular tear in the skin caused by a sharp object. Therefore, based on the definition of a contusion as a closed wound from blunt force trauma without breaking the skin, it is the correct choice in this scenario.

Correct Answer: C

Rationale: Correct Answer: C - The NA should report changes in the resident's respiratory rate. Rationale: Reporting changes in the resident's respiratory rate is crucial in oxygen therapy monitoring. It helps identify any potential respiratory distress or improvement. This information allows healthcare providers to adjust oxygen levels accordingly and provide appropriate care. Monitoring respiratory rate is a key aspect of ensuring the resident's safety and well-being. Summary of other choices: A: The NA should limit smoking to certain areas. - Smoking should be completely avoided near a resident receiving oxygen therapy to prevent fire hazards. B: The NA should reduce the number of pillows the resident uses. - Adjusting the number of pillows may affect the resident's comfort but does not directly relate to oxygen therapy. D: The NA should use petroleum-based lip balms to help with irritation. - Petroleum-based lip balms are flammable and should be avoided near oxygen therapy.
