Nursing Elites

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

• A. Hypothalamus
• B. Pituitary Gland
• C. Pons
• D. Medulla Oblongata

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. The healthcare professional is preparing to measure the length, weight, chest, and head circumference of a 6-month-old infant. Which measurement technique is correct?

• A. Measuring the infant's length using a tape measure
• B. Weighing the infant on an electronic standing scale
• C. Measuring the chest circumference at the nipple line with a tape measure
• D. Measuring the head circumference by wrapping the tape measure around the head

Correct answer: C

Rationale: For accurate measurements, specific techniques are required for different parameters in infants. Measuring the chest circumference involves encircling the chest at the nipple line. Length should be measured on a horizontal measuring board. Weight should be measured using a platform-type balance scale. Head circumference measurement entails ensuring the tape is aligned at the eyebrows and prominent frontal and occipital bones for the widest span. Therefore, the correct technique for measuring the chest circumference is at the nipple line with a tape measure. The other options are incorrect because length should be measured on a horizontal board, weight should be measured on a balance scale, and head circumference should be measured around the head, not over the nose and cheekbones.

3. When a patient is standing in anatomical position, where are their feet?

• A. Facing forward with the toes spread open
• B. Facing out to the sides to open the hips
• C. Side by side and facing forward; toes resting comfortably
• D. The feet are pointed inward.

Correct answer: B

Rationale: When a person is standing in anatomical position, their feet are side by side, and they are facing forward with the toes pointing out to the sides to open the hips. This position allows for proper alignment of the body for anatomical reference. Choice A is incorrect because the feet should not be spread open, but rather side by side. Choice C is incorrect as it does not mention the correct positioning of the feet. Choice D is incorrect as the feet should not be pointed inward, but rather facing out to the sides to open the hips.

4. Which action is appropriate for the nurse to delegate to unlicensed assistive personnel (UAP)?

• A. Listen to a patient's lung sounds for wheezes or rhonchi.
• B. Label specimens obtained during percutaneous lung biopsy.
• C. Instruct a patient about how to use home spirometry testing.
• D. Measure induration at the site of a patient's intradermal skin test.

Correct answer: B

Rationale: Labeling specimens obtained during a percutaneous lung biopsy is a task that can be appropriately delegated to unlicensed assistive personnel (UAP) as it does not require nursing judgment. UAP can perform this task safely under the supervision of a nurse. Listening to a patient's lung sounds for wheezes or rhonchi, instructing a patient about how to use home spirometry testing, and measuring induration at the site of a patient's intradermal skin test all require nursing judgment and interpretation of findings. These tasks should be performed by licensed nursing personnel to ensure accurate assessment and appropriate intervention.

5. When is the best time for the nurse to attempt to elicit the Moro reflex during an infant examination?

• A. When the infant is sleeping
• B. At the end of the examination
• C. Before auscultation of the thorax
• D. At about the middle of the examination

Correct answer: B

Rationale: The Moro reflex, also known as the startle reflex, is best elicited at the end of the examination because it can cause the infant to cry. This reflex is triggered by a sudden change in position or loud noise, and it involves the infant's arms extending and then coming back together as if embracing. By eliciting this reflex at the end of the examination, the nurse can observe the infant's response and ensure that the examination is completed without unnecessary distress. Choices A, C, and D are incorrect because the Moro reflex is typically elicited at the end of the examination to avoid disrupting the assessment process and causing unnecessary discomfort to the infant.
