Correct Answer: D

Rationale: Within cultures, various groups of people share different beliefs, values, and attitudes due to factors such as ethnicity, religion, education, occupation, age, and gender. When these distinct groups coexist within a broader culture, they are referred to as subcultures. While ethnicity, gender, and religion are important components of individuals' identities, they do not represent the concepts of family, cultures, or spirituality. The correct answer is 'Subcultures' as these categories reflect differences within a larger cultural context, emphasizing the unique characteristics shared by members of subcultural groups.

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.

Correct Answer: B

Rationale: The correct answer is the dorsal surface of the hand. The dorsa (backs) of the hands and fingers are best for determining temperature because the skin is thinner on the dorsal surfaces than on the palms. Fingertips are best for fine, tactile discrimination and not for assessing skin temperature. The ulnar and palmar surfaces of the hands are not as effective for assessing skin temperature as the dorsal surface because they have thicker skin layers.

Correct Answer: B

Rationale: In a situation where a patient is in significant respiratory distress, bilaterally percussing the thorax to note any differences in percussion tones is a crucial nursing intervention. Percussion provides instant feedback regarding changes in underlying tissue density, which can give important clues about the patient's physical status. This hands-on assessment technique is readily available and can be performed promptly. Counting the patient's respirations, while important, may not provide as much detailed information as percussion. Ordering a chest x-ray and waiting for the results can cause a delay in assessing and addressing the patient's immediate needs. Inspecting the thorax for new masses and bleeding, although relevant, may not offer as much real-time information about the patient's condition compared to percussion.

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.
