Exam Cram NCLEX RN Practice Questions Questions
Question 1 of 5
Which of these specific measurements is the best index of a child's general health?
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.
Question 2 of 5
During an examination, the nurse notices that a female patient has a round "moon"? face, central trunk obesity, and a cervical hump. Her skin is fragile with bruises. The nurse determines that the patient likely has which condition?
Correct Answer: C
Rationale: Cushing syndrome is characterized by weight gain and edema with central trunk and cervical obesity (buffalo hump) and a round, plethoric face (moon face). Excessive catabolism in Cushing syndrome causes muscle wasting, weakness, thin arms and legs, reduced height, and thin, fragile skin with purple abdominal striae, bruising, and acne. Gigantism is characterized by increased height and weight and delayed sexual development, which are not present in the patient. Acromegaly results from excessive growth hormone secretion in adulthood, leading to bone overgrowth in specific areas like the face, head, hands, and feet. Marfan syndrome is an inherited connective tissue disorder characterized by a tall, thin stature and distinct features not seen in this patient. The combination of signs described in the question aligns with the clinical presentation of Cushing syndrome.
Question 3 of 5
In which of these patients would rectal temperatures be measured?
Correct Answer: B
Rationale: Rectal temperature measurement is preferred in situations where other routes are impractical or when the most accurate measure is necessary, such as in critically ill patients. The rectal route may be chosen due to its reliability in such cases. For older adults, school-age children, and patients receiving oxygen via nasal cannula, rectal temperature measurement is not typically indicated. Other routes like oral, tympanic, or axillary measurements are more commonly used in these populations due to comfort, convenience, and non-invasive nature.
Question 4 of 5
The nurse is teaching a student nurse about the different types of thermometers. When teaching the student about the advantages of the tympanic membrane thermometer (TMT), which statement would the nurse include?
Correct Answer: B
Rationale: The correct answer is "The rapid measurement of the TMT is beneficial for uncooperative younger children." TMT is ideal for young children who may not cooperate for oral temperatures or fear rectal temperatures. However, using TMT for newborn infants is not recommended due to inconsistencies in results. Measuring temperature with TMT is not necessarily cost-effective. The most accurate method for measuring core temperature is through rectal temperatures. TMT may not be the preferred method for patients with otitis media due to potential inaccuracies caused by fluid behind the tympanic membrane.
Question 5 of 5
The healthcare provider is examining a patient who is reporting "feeling cold."? Which is a mechanism of heat loss in the body?
Correct Answer: B
Rationale: When the body needs to lose heat, one of the mechanisms it employs is radiation. Radiation involves the transfer of heat from the body to the environment in the form of infrared waves. While metabolism, exercise, and food digestion contribute to heat production, they are not mechanisms for heat loss. Metabolism generates heat as a byproduct, exercise increases metabolic rate leading to heat production, and food digestion involves some heat generation, but these processes do not directly facilitate heat loss. Therefore, in the scenario where the patient is feeling cold, radiation is the primary mechanism for the body to lose excess heat and maintain a stable internal temperature.
