Nursing Elites

1. The healthcare provider is preparing to use an otoscope for an examination. Which statement is true regarding the otoscope?

• A. Often used to direct light into the sinuses
• B. Used to examine the structures of the internal ear
• C. Uses a short, broad speculum to help visualize the ear
• D. Directs light into the ear canal and onto the tympanic membrane

Correct answer: D

Rationale: The otoscope is a tool used to examine the ear canal and tympanic membrane, which separates the external and middle ear. It is not intended to direct light into the sinuses or examine the internal structures of the ear. The otoscope typically uses a short, narrow speculum to aid in visualizing the ear canal and tympanic membrane, not a short, broad speculum as mentioned in choice C.

2. When considering the concepts related to blood pressure, which statement best describes the concept of mean arterial pressure (MAP)?

• A. MAP is the pressure of the arterial pulse.
• B. MAP reflects the stroke volume of the heart.
• C. MAP is the pressure forcing blood into the tissues, averaged over the cardiac cycle.
• D. MAP is an average of the systolic and diastolic blood pressures and reflects tissue perfusion.

Correct answer: C

Rationale: Mean Arterial Pressure (MAP) is the pressure that forces blood into the tissues, averaged over the cardiac cycle. It is not the pressure of the arterial pulse (Choice A), nor does it directly reflect the stroke volume of the heart (Choice B). While MAP involves systolic and diastolic pressures, it is not simply an average of these two values as diastole lasts longer. Instead, MAP is closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it represents the pressure forcing blood into the tissues, averaged over the cardiac cycle.

3. A patient's body temperature has varied over the last 24 hours from 97.6 degrees F in the morning to 99 degrees F in the evening. The patient is worried that this change in temperature may indicate the beginning of a fever. Which of the following BEST explains this phenomenon?

• A. The patient definitely has a fever in the evening and should be seen by a doctor.
• B. The patient is experiencing changes related to a diurnal rhythm.
• C. The patient is more than likely taking their temperature incorrectly.
• D. The patient is experiencing changes related to fluctuating daily hormones.

Correct answer: B

Rationale: The patient is experiencing changes related to a diurnal rhythm. Diurnal rhythm is the phenomenon of body temperature fluctuating depending on the time of day. Temperatures taken in the morning are typically lower than those taken throughout the rest of the day. Choice A is incorrect because a single elevated temperature reading in the evening does not definitively indicate a fever. Choice C is incorrect as there is no indication of incorrect temperature measurement. Choice D is incorrect as the temperature changes are not related to monthly hormones but rather to the body's natural daily rhythm.

4. What is the minimum amount of personal protective equipment for a nurse when working with a newborn immediately after a high-risk delivery in a client's room?

• A. Sterile gown, gloves
• B. Mask, gown, shoe covers
• C. Gloves
• D. Hat, mask, gloves, gown, shoe covers

Correct answer: C

Rationale: The correct answer is gloves. When attending a high-risk delivery and handling a newborn immediately after birth, the minimum personal protective equipment required for a nurse includes gloves. This is essential to protect the nurse from potential exposure to the mother's blood or body fluids that may be present on the newborn's skin. Choices A, B, and D include additional protective equipment that is not necessary for this specific scenario. Wearing gloves is crucial for infection control and to prevent the transmission of pathogens.

5. 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.
