Nursing Elites

1. Which of these specific measurements is the best index of a child's general health?

• A. Body mass index
• B. Height and weight
• C. Head circumference
• D. Chest circumference

Correct answer: B

Rationale: Height and weight are the most accurate measurements to assess a child's general health. These measurements reflect the physical growth and development of the child, indicating overall health status. Choices C and D, head circumference and chest circumference, are important measurements for specific assessments but do not provide as comprehensive an overview of general health as height and weight. Body mass index (BMI) is a calculation based on height and weight, making height and weight more direct and primary indicators of a child's health compared to BMI.

2. The mitral valve is synonymous with the term:

• A. Left ventricle
• B. Right atrium
• C. Bicuspid valve
• D. Tricuspid valve

Correct answer: C

Rationale: The mitral valve, also known as the bicuspid valve, is located between the left atrium and the left ventricle, regulating blood flow from the left atrium into the left ventricle. The term 'bicuspid' refers to the valve's two cusps or leaflets. This distinguishes it from the tricuspid valve (Choice D), which has three cusps, making Choice D incorrect. The left ventricle (Choice A) and right atrium (Choice B) are not synonymous with the mitral valve. Therefore, the correct answer is C: Bicuspid valve.

3. 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.

4. In which situation would the nurse use bimanual palpation technique?

• A. Palpating the thorax of an infant
• B. Palpating the kidneys and uterus
• C. Assessing pulsations and vibrations
• D. Assessing the presence of tenderness and pain

Correct answer: B

Rationale: Bimanual palpation involves using both hands to envelop or capture specific body parts or organs like the kidneys, uterus, or adnexa. This technique is particularly useful for assessing the size, shape, consistency, and mobility of deep organs like the kidneys and uterus. Palpating the thorax of an infant (Choice A) is usually done with a different technique like gentle, single-handed palpation. Assessing pulsations and vibrations (Choice C) and assessing tenderness and pain (Choice D) typically do not require the use of bimanual palpation, making Choices A, C, and D incorrect.

5. A triage nurse has four clients arrive in the emergency department within 15 minutes. Which client should the triage nurse send back to be seen first?

• A. A 2-month-old infant with a history of rolling off the bed and having a bulging fontanelle with crying
• B. A teenager who suffered singed facial hair while camping
• C. An elderly client with complaints of frequent liquid brown-colored stools
• D. A middle-aged client with intermittent pain behind the right scapula

Correct answer: B

Rationale: The correct answer is the teenager who suffered singed facial hair while camping. This client is in the greatest danger with a potential risk of respiratory distress. Singed facial hair indicates exposure to heat or fire in close range, which could have caused serious damage to the interior of the lungs. It's crucial to prioritize this client as the interior lining of the lungs has no nerve fibers, so swelling may not be immediately noticeable. The other choices, while concerning, do not present an immediate life-threatening situation. The infant's condition may be serious but does not pose an immediate danger of respiratory distress. The elderly client's symptoms could indicate gastrointestinal issues, which are important but not as urgent as potential respiratory compromise. The middle-aged client's pain behind the right scapula, while uncomfortable, does not indicate an acute life-threatening condition requiring immediate attention.
