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.

A 75-year-old client, hospitalized with a cerebral vascular accident (stroke), becomes disoriented at times and tries to get out of bed but is unable to ambulate without help. What is the most appropriate safety measure?
- A. Restrain the client in bed
- B. Ask a family member to stay with the client
- C. Check the client every 15 minutes
- D. Use a bed exit safety monitoring device
Correct Answer: D
Rationale: Option D is the most appropriate safety measure in this scenario. Using a bed exit safety monitoring device allows the client to retain some independence while ensuring that the nursing staff is alerted when assistance is needed. This solution promotes client safety without compromising their autonomy. Option A, restraining the client in bed, can lead to increased agitation, confusion, and a loss of independence. Option B, asking a family member to stay with the client, shifts the responsibility away from the healthcare team. Option C, checking the client every 15 minutes, is not a sufficient safety measure as the client could attempt to get out of bed in the unobserved interval, risking falls and injury.
A patient with Parkinson's disease is experiencing difficulty swallowing. What potential problem associated with dysphagia has the greatest influence on the plan of care?
- A. Anorexia
- B. Aspiration
- C. Self-care deficit
- D. Inadequate intake
Correct Answer: B
Rationale: When a person experiences dysphagia (difficulty swallowing), the greatest concern is aspiration. Aspiration occurs when food or fluids enter the trachea and lungs instead of going down the esophagus. This can lead to serious complications such as choking, airway obstruction, and aspiration pneumonia. Anorexia (Choice A) refers to a loss of appetite, which is not the primary concern with dysphagia. Self-care deficit (Choice C) and inadequate intake (Choice D) are important considerations but do not have as direct an impact on the immediate safety and health risks associated with aspiration in dysphagia.
The client is being discharged to a long-term care (LTC) facility. The nurse is preparing a progress note to communicate to the LTC staff the client's outcome goals that were met and those that were not. To do this effectively, the nurse should:
- A. Formulate post-discharge nursing diagnoses
- B. Draw conclusion about resolution of current client problems
- C. Assess the client for baseline data to be used at the LTC facility
- D. Plan the care that is needed in the LTC facility
Correct Answer: B
Rationale: To effectively communicate the client's outcome goals that were met and those that were not to the LTC staff, the nurse should draw conclusions about the resolution of the current client problems. Terminal evaluation is performed to determine the client's condition at discharge, focusing on which goals were achieved and which were not. Formulating post-discharge nursing diagnoses (option A) is not the most appropriate action in this scenario as it focuses on identifying potential problems after discharge rather than evaluating achieved goals. Assessing the client for baseline data (option C) is not necessary at this point as the focus is on evaluating outcomes rather than collecting baseline data. Planning the care needed in the LTC facility (option D) is premature as this should be done on admission to the LTC facility and not during the discharge process.
When caring for a patient with latex allergy, the healthcare provider creates a latex-safe environment by doing which of the following?
- A. Carefully cleaning the wall-mounted blood pressure device before using it.
- B. Donning latex gloves outside the room to limit powder dispersal.
- C. Using a latex-free pharmacy protocol.
- D. Placing the patient in a semi-private room.
Correct Answer: C
Rationale: Creating a latex-safe environment for a patient with latex allergy is crucial to prevent allergic reactions. Using a latex-free pharmacy protocol is essential as it ensures that medications and supplies provided to the patient are free of latex components. Cleaning a wall-mounted blood pressure device may not be sufficient as the device itself may contain latex parts that can trigger an allergic reaction. Donning latex gloves, even outside the room, is not recommended as powder dispersal can cause issues; only non-latex gloves should be used in a latex-safe environment. Placing the patient in a semi-private room does not directly address the need to eliminate latex exposure from medical supplies and equipment, which is better achieved through a latex-free pharmacy protocol.
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.
