Nursing Elites

1. An examiner is using an ophthalmoscope to examine a patient's eyes. The patient has astigmatism and is nearsighted. Which of these techniques by the examiner would indicate that the examination is being correctly performed?

• A. Rotating the lens selector dial to bring the object into focus
• B. Using the large full circle of light when assessing pupils that are not dilated
• C. Rotating the lens selector dial to the black numbers to compensate for astigmatism
• D. Using the grid on the lens aperture dial to visualize the external structures of the eye

Correct answer: A

Rationale: To correctly perform an eye examination using an ophthalmoscope on a patient with astigmatism and nearsightedness, the examiner should rotate the lens selector dial to bring the object into focus. This adjustment helps compensate for nearsightedness or farsightedness but does not correct astigmatism. Rotating the lens selector dial to the black numbers is not an appropriate technique for compensating for astigmatism. Using the grid on the lens aperture dial is primarily for visualizing external structures of the eye, not for addressing refractive errors. The large full circle of light is typically used when assessing dilated pupils, not for examining patients with astigmatism and nearsightedness. Therefore, the correct technique is rotating the lens selector dial to bring the object into focus.

2. Which of these actions illustrates the correct technique for a nurse when assessing oral temperature with a glass thermometer?

• A. Wait 30 minutes if the patient has ingested hot or iced liquids.
• B. Leave the thermometer in place for 3 to 4 minutes if the patient is afebrile.
• C. Shake the glass thermometer down to 35.5�C before taking the patient's temperature.
• D. Place the thermometer at the base of the tongue and ask the patient to close his or her lips.

Correct answer: B

Rationale: The correct technique for assessing oral temperature with a glass thermometer involves leaving the thermometer in place for 3 to 4 minutes if the patient is afebrile and up to 8 minutes if the patient is febrile. Waiting 30 minutes if the patient has ingested hot or iced liquids is incorrect; instead, the nurse should wait 15 minutes in such cases. Shaking the glass thermometer down to 35.5�C, not 37.5�C, is the correct procedure before taking the patient's temperature. Placing the thermometer at the base of the tongue, not the front, and asking the patient to close their lips is the proper way to position the thermometer. Therefore, the correct answer is to leave the thermometer in place for 3 to 4 minutes if the patient is afebrile and up to 8 minutes if the patient is febrile.

3. Which type of shock is related to low blood volume?

• A. Psychogenic
• B. Cardiogenic
• C. Anaphylactic
• D. Hemorrhagic

Correct answer: D

Rationale: Hemorrhagic shock, also known as hypovolemic shock, is directly related to low blood volume due to significant blood loss. In hemorrhagic shock, the body's circulating blood volume is reduced, leading to inadequate perfusion of tissues and organs. Psychogenic shock is caused by emotional distress, not blood volume changes. Cardiogenic shock results from heart failure, not low blood volume. Anaphylactic shock is due to a severe allergic reaction, not a reduction in blood volume.

4. While explaining an illness to a 10-year-old, what should the nurse keep in mind about the cognitive development at this age?

• A. They are able to make simple associations of ideas
• B. They are able to think logically in organizing facts
• C. Interpretation of events originates from their own perspective
• D. Conclusions are based on previous experiences

Correct answer: B

Rationale: At the age of 10, children are in the concrete operations stage according to Piaget. They are capable of mature thought when allowed to manipulate and organize objects. This means they can think logically, organize facts, and understand cause-and-effect relationships. Choices A, C, and D are incorrect. While simple associations of ideas may occur, the key cognitive ability at this stage is the capacity for logical thought and organization of information. Interpretation of events from their own perspective is more characteristic of younger children, and conclusions based on previous experiences are more aligned with older children or adults.

5. When measuring a patient's body temperature, what factor should be considered that can influence the temperature?

• A. Constipation
• B. Diurnal cycle
• C. Nocturnal cycle
• D. Patient's emotional state

Correct answer: B

Rationale: When measuring body temperature, it is essential to consider factors that can influence it. The diurnal cycle, which refers to the body's natural temperature variations throughout a 24-hour period, can impact body temperature readings. Factors like exercise, age, and environment can also affect body temperature. Constipation does not directly influence body temperature. The 'nocturnal cycle' is not a recognized term in relation to body temperature. While a patient's emotional state can affect vital signs, it is not a primary factor in influencing body temperature measurements.
