Nursing Elites

1. The healthcare professional is preparing to use a stethoscope for auscultation. Which statement is true regarding the diaphragm of the stethoscope?

• A. Used to listen for high-pitched sounds
• B. Used to listen for low-pitched sounds
• C. Should be firmly held against the person's skin to block out low-pitched sounds
• D. Should be lightly held against the person's skin to listen for extra heart sounds and murmurs

Correct answer: A

Rationale: The diaphragm of the stethoscope is designed for listening to high-pitched sounds like breath, bowel, and normal heart sounds. It should be firmly held against the person's skin to ensure optimal sound transmission, leaving a ring after use. On the other hand, the bell of the stethoscope is ideal for detecting soft, low-pitched sounds such as extra heart sounds or murmurs. Therefore, the diaphragm is not used to block out low-pitched sounds but rather to enhance the detection of high-frequency sounds.

2. The client reports nausea and constipation. Which of the following would be the priority nursing action?

• A. Collect a stool sample
• B. Complete an abdominal assessment
• C. Administer an anti-nausea medication
• D. Notify the physician

Correct answer: B

Rationale: The priority nursing action when a client reports symptoms like nausea and constipation is to complete an abdominal assessment. Assessment is crucial as it involves the systematic collection of data to understand the client's condition. By assessing the abdomen, the nurse can gather essential information to make a nursing diagnosis and develop a care plan. Collecting a stool sample (Choice A) may be necessary but comes after the assessment to confirm findings. Administering an anti-nausea medication (Choice C) addresses symptoms but does not address the underlying cause without a thorough assessment. Notifying the physician (Choice D) should come after the assessment to provide a complete picture of the client's condition.

3. When printing out an EKG, a nurse notices that the QRS complexes are extremely small. What should be the next step?

• A. Alert the physician immediately as this is a sign of impending cardiac arrest.
• B. Check to see that all leads are attached and rerun the EKG.
• C. Increase the sensitivity control to 20 mm deflection.
• D. Decrease the run speed to 50.

Correct answer: C

Rationale: Increasing the sensitivity control to 20 mm deflection will double the sensitivity, allowing for better observation of the small QRS complexes. This step is crucial in obtaining a clearer EKG reading. Choice A is incorrect because small QRS complexes do not necessarily indicate impending cardiac arrest; it's more likely a technical issue. Choice B is not the first step to take when small QRS complexes are observed; it's important to adjust the settings first. Choice D is incorrect because decreasing the run speed to 50 is not the appropriate action for this situation; adjusting the sensitivity control is more relevant to improve the visualization of the complexes.

4. 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: A

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.

5. Which principle of body mechanics may help to reduce the risk of a back injury?

• A. Maintain a wide base of support
• B. Bend from the knees, not the waist
• C. Keep the back straight while lifting
• D. Push or pull objects rather than lifting

Correct answer: C

Rationale: Proper body mechanics are crucial to prevent injuries, especially for professions involving lifting and moving objects. Keeping the back straight while lifting is essential to reduce the risk of back injuries as it helps maintain the spine's natural alignment and prevents excessive strain on the back muscles. Choosing choices A, B, and D would increase the risk of back injury. Maintaining a wide base of support provides stability, bending from the knees instead of the waist protects the lower back, and pushing or pulling objects reduces the strain on the back muscles, all contributing to preventing back injuries.
