Nursing Elites

1. 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

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.

2. Which of the following sets of word parts means 'Pain'?

• A. dynia and -algia
• B. a- and an
• C. ia and -ac
• D. pathy and -osis

Correct answer: A

Rationale: The correct answer is 'dynia and -algia.' The word parts 'dynia' and '-algia' specifically relate to pain. 'Dynia' refers to pain, and '-algia' also denotes pain. Therefore, when combined, they form the meaning 'pain.' Choices B, C, and D are incorrect because 'a-' and 'an' do not relate to pain, 'ia' and '-ac' do not specifically convey pain, and 'pathy' and '-osis' are not word parts that directly signify pain.

3. A patient has suddenly developed shortness of breath and appears to be in significant respiratory distress. After calling the physician and placing the patient on oxygen, which of these actions is the best for the nurse to take when further assessing the patient?

• A. Count the patient's respirations.
• B. Bilaterally percuss the thorax, noting any differences in percussion tones.
• C. Call for a chest x-ray and wait for the results before beginning an assessment.
• D. Inspect the thorax for any new masses and bleeding associated with respirations.

Correct answer: B

Rationale: In a situation where a patient is in significant respiratory distress, bilaterally percussing the thorax to note any differences in percussion tones is a crucial nursing intervention. Percussion provides instant feedback regarding changes in underlying tissue density, which can give important clues about the patient's physical status. This hands-on assessment technique is readily available and can be performed promptly. Counting the patient's respirations, while important, may not provide as much detailed information as percussion. Ordering a chest x-ray and waiting for the results can cause a delay in assessing and addressing the patient's immediate needs. Inspecting the thorax for new masses and bleeding, although relevant, may not offer as much real-time information about the patient's condition compared to percussion.

4. Which of the following actions is most appropriate for reducing the risk of infection during the post-operative period?

• A. Flush the central line with heparin at least every four hours
• B. Administer narcotic analgesics as needed
• C. Remove the urinary catheter as soon as the client is ambulatory
• D. Order a high-protein diet for the client

Correct answer: C

Rationale: The most appropriate action to reduce the risk of infection during the post-operative period is to remove the urinary catheter as soon as the client is ambulatory. Urinary catheters can serve as a source of bacteria, increasing the risk of infection in the bladder or urethra. By removing the catheter promptly once the client is mobile, the risk of infection can be minimized. Option A, flushing the central line with heparin, is not directly related to reducing urinary tract infections. Option B, administering narcotic analgesics as needed, is important for pain management but does not directly address infection prevention. Option D, ordering a high-protein diet, may be beneficial for wound healing but does not specifically target infection risk reduction in the post-operative period.

5. When should you wear gloves?

• A. preparing infant formula for a newborn baby
• B. transferring breast milk into a baby bottle
• C. knocking on a patient's door
• D. opening a patient's door

Correct answer: B

Rationale: You must wear gloves when transferring breast milk into a baby bottle because breast milk is considered a bodily fluid. It is essential to avoid direct contact to prevent contamination. When preparing infant formula, gloves are not required as formula is not a bodily fluid. Knocking on or opening a patient's door does not involve direct contact with bodily fluids, so gloves are unnecessary in those situations.
