Question 1 of 5
A new staff nurse completes orientation to the psychiatric unit. This nurse will expect to ask an advanced practice nurse to perform which action for patients?
Correct Answer: C
Rationale: Prescriptive privileges are granted to Master's-prepared nurse practitioners who have taken special courses on prescribing medications. The nurse prepared at the basic level performs mental health assessments, establishes relationships, and provides individualized care planning. In this scenario, the new staff nurse would ask the advanced practice nurse to prescribe psychotropic medications, as this is within their scope of practice and expertise. Establishing therapeutic relationships, performing mental health assessments, and individualizing care plans are typically responsibilities of staff nurses at the basic level, not advanced practice nurses.
Question 2 of 5
When counting an infant's respirations, which technique is correct?
Correct Answer: B
Rationale: The correct technique for counting an infant's respirations is to observe the movement of the abdomen. Infants typically have more diaphragmatic breathing than thoracic, so watching the abdomen provides a more accurate count. Placing a hand on the chest or listening with a stethoscope can alter the infant's breathing pattern and provide inaccurate results.
Therefore, options A, C, and D are incorrect methods for counting an infant's respirations. By observing the movement of the abdomen, healthcare providers can accurately assess an infant's respiratory rate without influencing their breathing pattern.
Question 3 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 4 of 5
How many cc are there in 25 ounces?
Correct Answer: C
Rationale:
To convert ounces to cc, we know that there are 30 cc in 1 ounce.
Therefore, to find out how many cc are in 25 ounces, we multiply 30 cc/ounce by 25 ounces which equals 750 cc. This makes choice C, 750, the correct answer.
Choices A, B, and D are incorrect as they do not correctly convert ounces to cc.
Question 5 of 5
Why should a palpated pressure be performed before auscultating blood pressure?
Correct Answer: B
Rationale: Performing a palpated pressure before auscultating blood pressure helps in detecting the presence of an auscultatory gap. An auscultatory gap is a period during blood pressure measurement when Korotkoff sounds temporarily disappear before reappearing. Inflation of the cuff 20 to 30 mm Hg beyond the point where a palpated pulse disappears helps in identifying this gap. This technique ensures accurate blood pressure measurement by preventing the underestimation of blood pressure values. The other options are incorrect because palpating the pressure is not primarily done to hear Korotkoff sounds more clearly, avoid missing falsely elevated blood pressure, or readily identify a specific phase of Korotkoff sounds.
