HESI Fundamentals Exam

Correct Answer: A

Rationale: Pharyngeal diphtheria is primarily spread through droplet transmission, which occurs when an infected person coughs, sneezes, or talks, releasing respiratory droplets containing the bacteria. Therefore, the correct precaution for caring for a client with pharyngeal diphtheria is droplet precautions. Droplet precautions help prevent the transmission of respiratory pathogens over short distances via respiratory droplets. Contact precautions are used for diseases spread through direct or indirect contact with the patient or their environment. Airborne precautions are used for diseases that spread through small droplets suspended in the air. Standard precautions are basic infection prevention practices applying to all patient care.

Correct Answer: C

Rationale: Encouraging bed rest and quiet activities is crucial for a child recovering from a splenectomy with low hemoglobin and hematocrit levels. This approach helps conserve energy, promotes healing, and allows the body to focus on rebuilding red blood cells. Limiting milk and milk products (Choice A) is not directly related to improving the child's condition. Encouraging bed rest and quiet activities (Choice B) is appropriate as it helps in conserving energy and preventing physical exertion. Promoting a diet rich in iron (Choice D) is beneficial for improving hemoglobin levels in the long term, but immediate rest and recovery take precedence in this scenario.

Correct Answer: C

Rationale: The appropriate nursing response in this situation is to ask the client if there are any concerns about the procedure. By doing so, the nurse acknowledges the client's distress and opens up a dialogue to address any anxieties or misconceptions. Option A is incorrect as ignoring the client's discomfort can lead to increased anxiety and potential harm. Option B is not ideal as reassuring the client without addressing specific concerns may not alleviate the client's distress. Option D is incorrect because proceeding with the procedure without addressing the client's unspoken concerns can further escalate the client's distress.

Correct Answer: A

Rationale: When an irregular pulse is detected, it is essential to count the apical pulse rate for a full minute to accurately determine the rhythm. This ensures a comprehensive assessment and helps in identifying any potential issues or abnormalities. Rechecking the pulse at the same site after 5 minutes (Choice B) may not provide an immediate understanding of the irregularity. Measuring the client's blood pressure (Choice C) is important but not directly related to addressing the irregular pulse. Recording the irregularity and continuing with other vital signs (Choice D) may overlook a potentially serious cardiac issue that requires immediate attention.

Correct Answer: C

Rationale: The most appropriate intervention for a client with amphetamine toxicity and sensory overload is to provide a private room and limit stimulation. This approach helps reduce external stimuli, which can exacerbate sensory overload, and creates a calming environment for the client. Encouraging visitors to distract the client may worsen sensory overload by adding more stimulation. Speaking softly, rather than at a higher volume, is more suitable to help maintain a calm environment. Therefore, the correct choice is to provide a private room and limit stimulation (option C) in this scenario.
