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 these specific measurements is the best index of a child's general health?

• A. Body mass index
• B. Height and weight
• C. Head circumference
• D. Chest circumference

Correct answer: B

Rationale: Height and weight are the most accurate measurements to assess a child's general health. These measurements reflect the physical growth and development of the child, indicating overall health status. Choices C and D, head circumference and chest circumference, are important measurements for specific assessments but do not provide as comprehensive an overview of general health as height and weight. Body mass index (BMI) is a calculation based on height and weight, making height and weight more direct and primary indicators of a child's health compared to BMI.

3. Which nursing intervention is most appropriate to reduce environmental stimuli that may cause discomfort for a client?

• A. Loosen pressure dressings on wounds
• B. Use assistance to lift a client in bed
• C. Check temperature of water used in a sponge bath
• D. Position the client in a prone position

Correct answer: C

Rationale: To reduce environmental stimuli that may cause discomfort for a client, nurses can implement various interventions. Checking the temperature of the water used in a sponge bath is crucial to prevent burns from water that is too hot or discomfort from water that is too cold. This intervention addresses a common source of discomfort for clients during personal care. Loosening pressure dressings on wounds, although important for wound care, does not directly address environmental stimuli. Using assistance to lift a client in bed is about proper positioning and preventing injury rather than reducing environmental stimuli. Positioning the client prone is not a suitable intervention for reducing discomfort caused by environmental stimuli.

4. A healthcare professional is preparing to administer a dose of platelets to a client. Which of the following actions must the healthcare professional perform before giving the platelets?

• A. Start an IV of 0.9% Normal Saline to administer with the platelets
• B. Ensure the container with the platelets is intact and not damaged
• C. Verify the client's identity using two unique identifiers
• D. Check the client's chart to ensure no contraindications to platelet transfusion

Correct answer: B

Rationale: Before administering platelets, it is crucial to check the integrity of the container holding the blood product. An intact container ensures the sterility and safety of the platelets, minimizing the risk of contamination or infection. Option A is incorrect as administering platelets typically does not require starting a new IV line unless indicated for the specific patient. Option C is not the priority as verifying the client's identity can be done at any point during the administration process but is not specific to the platelet transfusion itself. Option D, checking the client's chart for antibiotic use, is not directly related to ensuring the safety of the blood product container.

5. All of the following factors may contribute to client falls EXCEPT:

• A. Contact dermatitis
• B. Urinary frequency
• C. Decreased visual acuity
• D. Confusion

Correct answer: A

Rationale: Client falls can result from various factors, both intrinsic and extrinsic. Intrinsic factors include health conditions like urinary frequency, which increases the need for bathroom visits, decreased visual acuity, and confusion. These factors can directly contribute to an increased risk of falls. However, contact dermatitis does not directly lead to falls. Contact dermatitis is a skin condition caused by contact with irritants or allergens and does not inherently predispose individuals to falling. Therefore, among the given options, contact dermatitis is the only factor that is not directly associated with an increased risk of falls.
