How far into the rectum should a rectal thermometer be inserted?

Correct Answer: B

Rationale: The correct answer is B: ½ to 1 inch. A rectal thermometer should be inserted approximately ½ to 1 inch into the rectum for an accurate reading. This depth ensures that the thermometer tip reaches the rectal wall where it can measure core body temperature effectively. Option A (¼ to ½ inch) is too shallow and may not provide an accurate reading. Option C (¾ to 1 inch) and Option D (½ to ¾ inch) are both slightly outside the recommended range and may not be as precise in capturing core body temperature. It's crucial to follow proper insertion guidelines to obtain an accurate temperature reading while ensuring the patient's comfort and safety.

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.

Correct Answer: C

Rationale: The correct answer is C: Burns. Diminished sensation following a cerebrovascular accident can lead to the inability to feel pain or temperature changes, increasing the risk of burns from hot surfaces or liquids. This is because the individual may not be able to sense when they are being burned, making them more susceptible to injuries. Rashes and warts (Option A) are not directly related to diminished sensation. Decreased urination (Option B) is more likely to be associated with issues in the urinary system rather than diminished sensation. Seizures (Option D) are neurological events that are not directly caused by diminished sensation.
