1. Which brain structure serves as the heat-regulating center?

• A. Hypothalamus
• B. Pituitary Gland
• C. Pons
• D. Medulla Oblongata

Correct answer: A

Rationale: The correct answer is the Hypothalamus. The hypothalamus is responsible for regulating body temperature, ensuring it stays within a narrow range. Moreover, the hypothalamus controls various essential bodily functions, such as hunger, thirst, and circadian rhythms. Choices B, C, and D are incorrect because the Pituitary Gland primarily produces and releases hormones, the Pons is involved in functions like sleep, respiration, and bladder control, and the Medulla Oblongata controls vital functions like breathing and heart rate, but not body temperature regulation.

2. Which of the following descriptions best describes the function of the thyroid gland?

• A. The thyroid gland converts glucose into glycogen
• B. The thyroid gland secretes cortisol during times of stress
• C. The thyroid gland regulates body metabolism
• D. The thyroid gland affects skin pigmentation

Correct answer: C

Rationale: The thyroid gland is responsible for secreting thyroxine (T4) and triiodothyronine (T3), which work to regulate the metabolism of the body's cells. The primary function of the thyroid gland is to control the body's metabolic rate, affecting processes such as heart rate, temperature regulation, and energy levels. Choices A, B, and D are incorrect because the thyroid gland is not involved in converting glucose into glycogen, secreting cortisol, or affecting skin pigmentation. Instead, the primary role of the thyroid gland is to regulate the metabolism and energy balance in the body.

3. During an examination, a nurse notices a draining ulceration on a patient's lower leg. What is the most appropriate action in this situation?

• A. Wash hands and then contact the physician.
• B. Continue to examine the ulceration and then wash hands.
• C. Wash hands, put on gloves, and continue with the examination of the ulceration.
• D. Wash hands, proceed with the rest of the physical examination, and perform the examination of the leg ulceration last.

Correct answer: C

Rationale: In this scenario, the most appropriate action is to wash hands, put on gloves, and then continue examining the ulceration. Wearing gloves is crucial when there is a possibility of contact with body fluids, as in the case of a draining ulceration. Contacting the physician is not necessary at this point; the immediate focus should be on proper infection control by washing hands and wearing gloves. Changing the order of the examination is not recommended as it is important to follow a systematic approach to avoid missing any crucial assessments.

4. The nurse is preparing to examine a 4-year-old child. Which action by the nurse is appropriate for this age group?

• A. Explain the procedures briefly to alleviate the child's anxiety.
• B. Give the child feedback and reassurance during the examination.
• C. Ask the child to undress as needed for the examination.
• D. Perform an examination of the head last.

Correct answer: B

Rationale: For a 4-year-old child, short and simple explanations should be provided to avoid overwhelming the child. It is important to give feedback and reassurance during the examination to create a comforting environment for the child. Asking the child to undress as needed is appropriate for a thorough examination, as children at this age are usually willing to do so. Performing an examination of the head last allows the child to become more comfortable during the assessment. Therefore, the most appropriate action for a 4-year-old child is to provide feedback and reassurance during the examination, ensuring a positive experience for the child.

5. Which of the following descriptors is most appropriate to use when stating the 'problem' part of a nursing diagnosis?

• A. Grimacing
• B. Anxiety
• C. Oxygenation saturation 93%
• D. Output 500 mL in 8 hours

Correct answer: B

Rationale: The problem part of a nursing diagnosis in the context of nursing care plans should focus on the client's response to a life process, event, or stressor. This response is what is used to identify the nursing diagnosis. 'Anxiety' is the most appropriate descriptor for the problem part of a nursing diagnosis as it reflects a psychological response that can be addressed by nursing interventions. 'Grimacing' is a physical manifestation and not the problem itself. 'Oxygenation saturation 93%' and 'Output 500 mL in 8 hours' are data points or cues that a nurse would use to formulate the nursing diagnostic statement, not the actual problem being addressed.
