Nursing Elites

1. When percussing over the lungs of a 4-year-old child, the nurse hears bilateral loud, long, and low tones. How should the nurse proceed?

• A. Palpate over the area for increased pain and tenderness.
• B. Ask the child to take shallow breaths and percuss over the area again.
• C. Refer the child to a specialist because of an increased amount of air in the lungs.
• D. Consider this finding as normal for a child this age and proceed with the examination.

Correct answer: Consider this finding as normal for a child this age and proceed with the examination.

Rationale: In pediatric patients, loud, long, and low tones heard when percussing over the lungs are normal findings. These percussion notes are characteristic of a child's lung due to its thin chest wall and increased air content. It is unnecessary to palpate for pain and tenderness, ask the child to take shallow breaths and repeat the percussion, or refer the child to a specialist. Therefore, the correct action is to consider these findings as normal for the child's age and continue with the examination.

2. The Sinoatrial Node (SA) is located within which of the following heart structures?

• A. Mitral Valve
• B. Right Ventricle
• C. Right Atrium
• D. Left Atrium

Correct answer: C: Right Atrium

Rationale: The Sinoatrial (SA) Node, often called the heart's natural pacemaker, is situated within the upper wall of the Right Atrium. It initiates the electrical impulses that regulate the heartbeat. Choices A, B, and D are incorrect because the SA node is not located in the Mitral Valve, Right Ventricle, or Left Atrium. It is specifically positioned in the Right Atrium to coordinate the heart's rhythm and timing.

3. 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: Leave the thermometer in place for 3 to 4 minutes if the patient is afebrile.

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.

4. What does the term 'Afferent Nerve' mean?

• A. Carrying an impulse to the brain
• B. Carrying an impulse away from the brain
• C. Carrying impulses to the motor neurons of the appendicular muscles
• D. None of the above

Correct answer: Carrying an impulse to the brain

Rationale: The correct answer is 'Carrying an impulse to the brain.' Afferent nerves are sensory nerves that carry signals from sensory receptors towards the central nervous system, including the brain. Choice B, 'Carrying an impulse away from the brain,' is incorrect as this describes efferent nerves which carry signals from the central nervous system to muscles and glands. Choice C, 'Carrying impulses to the motor neurons of the appendicular muscles,' is incorrect as it describes a different type of nerve function. Choice D, 'None of the above,' is incorrect as the correct definition of afferent nerve is indeed 'Carrying an impulse to the brain.'

5. An adult's blood pressure reads 40/20. You place the patient in a Trendelenberg position before rechecking the blood pressure. What actions will you take to position the patient correctly?

• A. lower the head of the bed and raise the foot of the bed
• B. raise the head of the bed up to about 60 to 75 degrees
• C. raise the head of the bed up to about 75 to 90 degrees
• D. raise the siderails and place the bed in the high position

Correct answer: lower the head of the bed and raise the foot of the bed

Rationale: In a Trendelenberg position, used for low blood pressure, the correct action is to lower the head of the bed and raise the foot of the bed. This positioning facilitates the return of blood to the heart and helps increase blood pressure. Option B, raising the head of the bed to 60 to 75 degrees, is incorrect as it is not the Trendelenberg position. Option C, raising the head of the bed to 75 to 90 degrees, is incorrect as it does not align with the Trendelenberg position. Option D, raising the siderails and placing the bed in the high position, is incorrect as it does not address the specific positioning required for the Trendelenberg position.
