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 according to the World Health Organization classification. This range indicates higher than normal body weight relative to height, which can increase health risks. Choice A (30 to 39) is categorized as obese, not overweight. Choice B (40 or higher) is classified as morbidly obese, significantly higher than overweight. Choice D (20 to 25) falls within the normal weight range, not overweight. Therefore, the correct answer is C as it accurately represents the BMI range for individuals classified as overweight.

Correct Answer: D

Rationale: The correct answer is D: 5 to 8 minutes. Waiting 5 to 8 minutes allows sufficient time for the chemical reaction to occur in the occult blood test, providing accurate results. Waiting too short of a time (A, B, C) may lead to false negatives or positives as the reaction may not be complete. Therefore, the nursing assistant should wait 5 to 8 minutes to ensure the test is reliable and accurate.

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 like frequent urination, difficulty starting or maintaining a urine stream. Genital herpes (A) is a sexually transmitted infection causing sores in the genital area. Erectile dysfunction (B) is the inability to achieve or maintain an erection. Prostate cancer (C) is a malignant tumor in the prostate gland, which may not always cause urinary symptoms. Therefore, based on the symptoms described in the question, BPH is the most appropriate choice.

Correct Answer: A

Rationale: The correct answer is A: Contusion. A contusion is a closed wound caused by blunt force trauma, leading to bruising and tissue damage without breaking the skin. Choice B, Puncture, involves penetration of the skin by a sharp object. Choice C, Incision, is a deliberate cut made with a sharp object. Choice D, Laceration, is a jagged cut caused by a sharp object tearing the skin. Therefore, the correct answer is A as it specifically refers to a closed wound resulting from blunt force trauma.

Correct Answer: C

Rationale: The correct answer is C because reporting changes in the resident's respiratory rate is crucial in monitoring the effectiveness of oxygen therapy and detecting any potential issues. This allows for prompt intervention if needed. A: This choice is incorrect as limiting smoking to certain areas does not directly relate to caring for a resident receiving oxygen therapy. B: Reducing the number of pillows may or may not be necessary for a resident on oxygen therapy, but it is not a specific guideline for their care. D: Using petroleum-based lip balms can be dangerous near oxygen therapy as they are flammable, posing a risk to the resident.
