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. In the Gram Stain procedure, which component acts as the mordant?

• A. Crystal violet
• B. Methyl alcohol
• C. Iodine
• D. Safranin

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

3. How does the procedure for taking a pulse rate on an infant differ from an adult?

• A. Pulse rates are taken on infants using a different method.
• B. The apical pulse method is used on infants.
• C. Pulse rates on infants are taken with a sphygmomanometer.
• D. Pulse rates on infants are taken apically in the third intercostal space.

Correct answer: B

Rationale: The correct answer is B: The apical pulse method is used on infants. This method involves placing a stethoscope in the fifth intercostal space, mid-clavicular line, and counting the beats for a full minute. It is a preferred method for infants due to their small size and the difficulty in palpating peripheral pulses accurately. Choices A, C, and D are incorrect. Choice A is incorrect as pulse rates are indeed taken on infants, albeit using a different method. Choice C is incorrect as a sphygmomanometer is typically used for measuring blood pressure, not pulse rates. Choice D is incorrect as pulse rates on infants are usually taken apically in the fifth intercostal space, not the third.

4. During a client interview, which of the following leading questions should the nurse avoid asking?

• A. What medication do you take at home?
• B. You are really excited about the plastic surgery, aren't you?
• C. Were you aware I've had this same type of surgery?
• D. What would you like to talk about?

Correct answer: B

Rationale: The nurse should avoid asking leading questions during a client interview as they can influence the client's response. Option B is a leading question as it suggests an expected response from the client, potentially biasing the information provided. This can lead to inaccurate data collection and subsequent errors in diagnostic reasoning. Choices A, C, and D are open-ended questions that encourage the client to provide unbiased information and allow for a more comprehensive assessment.

5. The nurse is preparing to assess a hospitalized patient who is experiencing significant shortness of breath. How should the nurse proceed with the assessment?

• A. Have the patient lie down to obtain an accurate cardiac, respiratory, and abdominal assessment.
• B. Obtain a thorough history and physical assessment from the patient's family member.
• C. Immediately perform a complete history and physical assessment to obtain baseline information.
• D. Examine the body areas relevant to the problem and complete the rest of the assessment after the problem has resolved.

Correct answer: D

Rationale: When assessing a patient experiencing significant shortness of breath, it is crucial to prioritize the evaluation of areas directly related to the problem. Having the patient lie down may exacerbate the breathing difficulty. Therefore, the nurse should focus on examining the body areas pertinent to the issue, such as the respiratory and cardiac systems. Completing the rest of the assessment can be deferred until after addressing the immediate problem. Obtaining a complete history or involving family members should come after addressing the acute issue to ensure the patient's safety and comfort.
