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. When turning an immobile bedridden client without assistance, which action by the nurse best ensures client safety?

• A. Securely grasp the client's arm and leg.
• B. Put bed rails up on the side of bed opposite from the nurse.
• C. Correctly position and use a turn sheet.
• D. Lower the head of the client's bed slowly

Correct answer: B

Rationale: When turning an immobile bedridden client without assistance, the best action to ensure client safety is to put bed rails up on the side of the bed opposite from the nurse. This is important because the nurse can only stand on one side of the bed, so having bed rails on the opposite side prevents the client from falling out of bed. Option A, which suggests securely grasping the client's arm and leg, can potentially cause client injury to the skin or joints. Options C and D, correctly positioning and using a turn sheet, and lowering the head of the client's bed slowly, respectively, are useful techniques during client turning but are of lower priority in terms of safety compared to the use of bed rails.

3. When a nurse's hand comes in contact with a client's blood after providing wound care, what is the next action the nurse should take?

• A. Use an alcohol-based hand sanitizer to disinfect the hands
• B. Wash hands with soap and water using appropriate technique
• C. Notify the appropriate personnel about the exposure to client's blood
• D. Sample some of the client's blood to determine the presence of diseases

Correct answer: B

Rationale: When a nurse's hand comes in contact with a client's blood, it is important to follow appropriate infection control measures. Using an alcohol-based hand sanitizer is not sufficient in this scenario as the blood is a visible contaminant. The best practice is to wash hands with soap and water using appropriate technique to ensure thorough cleansing and removal of any potential pathogens. Notifying the appropriate personnel about the exposure is important for documentation and further evaluation, but immediate hand hygiene is crucial. Sampling the client's blood for disease determination is not within the nurse's scope of practice and is unnecessary in this situation.

4. Which of the following questions is considered open-ended?

• A. What time did you last take your medications?
• B. Are you feeling okay right now?
• C. Please describe your symptoms.
• D. What day are you available for a follow-up appointment?

Correct answer: C

Rationale: The correct answer is 'Please describe your symptoms.' This question is considered open-ended because it encourages the respondent to provide a detailed and descriptive answer, fostering a more elaborate response. Open-ended questions are designed to prompt thoughtful and detailed responses. Choice A is a closed-ended question since it seeks a specific time for the medication intake. Choice B is also closed-ended as it can be answered with a simple 'yes' or 'no,' limiting the response. Choice D is closed-ended as it requests a specific day for the follow-up appointment, restricting the range of possible responses.

5. 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.
