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

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 vital signs can be expected in a child that is afebrile?

Correct answer: C

Rationale: The correct answer is the axillary temperature of 98.6 degrees F. Afebrile means without a fever, and an axillary temperature, which is taken in the armpit, is considered normal at 98.6 degrees F. Choice A is incorrect as a rectal temperature of 100.9 degrees F indicates a fever. Choice B is incorrect as an oral temperature of 38 degrees C is also indicative of a fever. Choice D is incorrect as not all options are wrong; only choices A and B are incorrect for an afebrile child.

3. Which of these statements is true regarding the use of Standard Precautions in the healthcare setting?

Correct answer: C

Rationale: Standard Precautions are designed to reduce the risk for transmission of microorganisms from both recognized and unrecognized sources. They are intended for use with all patients, regardless of their risk or presumed infection status. Standard Precautions apply to all body fluids, secretions, and excretions except sweat - whether or not they contain visible blood, non-intact skin, or mucous membranes. Hands should be washed with soap and water if visibly soiled with blood or body fluids. Alcohol-based hand rubs can be used if hands are not visibly soiled. Choice A is incorrect because Standard Precautions apply to all body fluids, secretions, and excretions except sweat. Choice B is incorrect because alcohol-based hand rub should be used when hands are not visibly dirty. Choice D is incorrect because Standard Precautions are not limited to situations involving non-intact skin, excretions with visible blood, or expected mucous membrane contact.

4. The nurse is assessing the vital signs of a 20-year-old marathon runner and documents the following vital signs: temperature"?36�C; pulse"?48 beats per minute; respirations"?14 breaths per minute; blood pressure"?104/68 mm Hg. Which statement is true concerning these results?

Correct answer: B

Rationale: The correct answer is, 'These are normal vital signs for a healthy, athletic adult.' A pulse rate of 48 beats per minute is considered bradycardia in adults, but it is not a concern in well-trained athletes like marathon runners. Bradycardia is a normal physiological response to aerobic conditioning. Tachycardia, on the other hand, is defined as a pulse rate above 100 beats per minute, which is not the case here. The low pulse rate in this scenario is a reflection of the athlete's cardiovascular fitness. Therefore, there is no need to notify the physician or schedule a follow-up visit based on these findings.

5. In which of the following ways can a nurse promote sleep for a client experiencing insomnia?

Correct answer: D

Rationale: A nurse can promote sleep for a client experiencing insomnia by addressing factors that may hinder sleep. Cold feet can disrupt sleep, so providing the client with socks to keep their feet warm can enhance comfort and aid in promoting sleep. The correct answer focuses on a direct intervention to address a specific issue that can impact sleep quality. Choices A, B, and C do not directly address the issue of cold feet, which is a common problem that can interfere with sleep in individuals with insomnia. Assisting the client to use the bathroom, giving a massage in the morning, or tucking in bed sheets tightly do not target the discomfort caused by cold feet, making them less effective interventions for promoting sleep in this scenario.
