Nursing Elites

1. What type of blood pressure measurement error is most likely to occur if the nurse does not check for the presence of an auscultatory gap?

• A. Diastolic blood pressure may not be heard.
• B. Diastolic blood pressure may be falsely low.
• C. Systolic blood pressure may be falsely low.
• D. Systolic blood pressure may be falsely high.

Correct answer: C

Rationale: If an auscultatory gap is undetected, a falsely low systolic reading may occur. This gap can lead to an underestimation of the systolic blood pressure, causing potential misinterpretation of the patient's condition. The diastolic blood pressure may not be heard due to the gap, but the critical issue in this scenario is the risk of underestimating systolic blood pressure, which can impact clinical decision-making. Choices B, C, and D are incorrect because the key concern in this context is the potential for a falsely low systolic blood pressure reading when an auscultatory gap is not assessed.

2. To which of the following do the CDC Standard precautions recommendations apply?

• A. Patients with diagnosed infections only
• B. Blood or body fluids with visible blood only
• C. All body fluids including sweat
• D. All patients receiving care in hospitals

Correct answer: D

Rationale: The correct answer is 'All patients receiving care in hospitals.' Standard precautions apply to all patients in healthcare settings, regardless of their infection status. These recommendations include all body fluids except sweat, non-intact skin, and mucous membranes. Choice A is incorrect as standard precautions are not limited to patients with diagnosed infections. Choice B is incorrect as standard precautions extend beyond blood or body fluids with visible blood. Choice C is incorrect as sweat is an exception to the body fluids covered under standard precautions.

3. 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.

4. Which body plane divides the body into right and left sides?

• A. Frontal Plane
• B. Medial Plane
• C. Median Plane
• D. Transverse Plane

Correct answer: C

Rationale: The correct answer is the Median Plane, also known as the sagittal plane. It divides the body into right and left sides. The Frontal Plane, or coronal plane, divides the body into front and back sections. The Transverse Plane divides the body into superior (upper) and inferior (lower) sections. Therefore, choices A, B, and D are incorrect as they do not specifically divide the body into right and left sides.

5. When performing a physical examination, safety must be considered to protect the examiner and the patient against the spread of infection. Which of these statements describes the most appropriate action the nurse would take when performing a physical examination?

• A. Washing one's hands after removing gloves is necessary, even if the gloves are still intact
• B. Hands are washed before and after every physical patient encounter
• C. Hands are washed before the examination of each body system to prevent the spread of bacteria from one part of the body to another
• D. Gloves are worn throughout the entire examination to demonstrate concern regarding the spread of infectious diseases

Correct answer: B

Rationale: The most appropriate action for the nurse to take when performing a physical examination is to wash their hands before and after every physical patient encounter. This practice helps prevent the spread of infection. Hands should also be washed after contact with blood, body fluids, secretions, and excretions, and after contact with any equipment contaminated with body fluids. It is crucial to wash hands after removing gloves, even if the gloves appear intact. Choice A is incorrect because washing hands after removing gloves is necessary to ensure thorough hygiene. Choice C is incorrect because hands should be washed before and after every patient encounter, not just before examining each body system. Choice D is incorrect because gloves should be worn when there is potential contact with body fluids, but they do not need to be worn throughout the entire examination.
