When the body is exposed to an allergen what substance is released?
- A. Lymph
- B. Histamine
- C. Hormones
- D. Platelets
Correct Answer: B
Rationale: When the body is exposed to an allergen, the immune system releases histamine. Histamine is a key player in triggering allergic reactions by causing inflammation, itching, and other symptoms. Lymph is involved in the immune response but is not directly released in response to allergens. Hormones and platelets are not the primary substances released in response to allergens.

- A. 64 beats per minute
- B. 72 beats per minute
- C. 58 beats per minute
- D. 88 beats per minute

The abnormality in choice C warrants further investigation as it may indicate bradycardia or other underlying health conditions.

This is important for maintaining their comfort and preventing hair loss. Choice B is incorrect as hairstyles should be chosen based on residents' preferences and comfort, not based on looking cute. Choice C is incorrect as cutting residents' hair should be done by a professional hairdresser, not by nursing assistants. Choice D is incorrect as pediculosis (lice) can indeed spread quickly if not treated promptly and properly.

Which of the following needs to be reported to the nurse?
- A. Burning or pressure when urinating
- B. Urinary output of 1200 to 1500 mL per day
- C. Pale yellow urine
- D. Clear urine
Correct Answer: A
Rationale: The correct answer is A because burning or pressure when urinating can indicate a urinary tract infection or other issue that requires medical attention. This symptom may suggest an underlying infection or inflammation in the urinary system. Reporting this to the nurse promptly can lead to early diagnosis and treatment. Choices B, C, and D are incorrect as they do not indicate any immediate health concern. Urinary output within the range of 1200 to 1500 mL per day is considered normal. The color of urine can vary based on hydration levels and dietary intake, so pale yellow or clear urine is not necessarily alarming.
