A nurse is reviewing the EKG strip of a client who has End Stage Renal Disease (ESRD) and has missed hemodialysis. Which of the following abnormalities on the client's EKG should the nurse interpret as a sign of hyperkalemia?
Prolonged P-R interval
Peaked T waves
Elevated ST segment
Inverted P wave
The Correct Answer is B
A. Prolonged P-R interval: A prolonged P-R interval may indicate an atrioventricular (AV) block or conduction delay, but it is not specifically associated with hyperkalemia.
B. Peaked T waves: Peaked T waves are a classic EKG finding in hyperkalemia. Hyperkalemia can affect cardiac repolarization, leading to tall, peaked T waves on the EKG.
C. Elevated ST segment: An elevated ST segment may indicate myocardial injury or ischemia but is not typically associated with hyperkalemia.
D. Inverted P wave: An inverted P wave may indicate atrial enlargement or conduction abnormalities but is not specifically associated with hyperkalemia.

Correct Answer is ["A","C","D"]
Explanation
A. Health care providers should be told about the diagnosis to deliver safe care: Health care providers need to know the client's diagnosis to provide appropriate and safe care. This includes administering medications, assessing for opportunistic infections, and implementing preventive measures.
B. Most people in current society would be accepting of the diagnosis: While stigma surrounding HIV/AIDS has decreased over time, disclosure is a personal decision, and not all individuals may be accepting of the diagnosis. Therefore, this statement may not always be accurate.
C. Intimate partners should be told so they can protect themselves: Disclosing the diagnosis to intimate partners is essential for their health and well-being, as it allows them to take necessary precautions to prevent transmission of the virus.
D. The diagnosis is reportable to the state health department: In many jurisdictions, HIV/AIDS diagnoses are reportable to the state health department for surveillance and public health monitoring purposes. This reporting is typically done without disclosing the client's identity.
E. Secrecy about the diagnosis is the privilege of the client: While confidentiality is crucial, it's important to balance it with public health considerations and the well-being of others who may be at risk of infection.
Correct Answer is B
Explanation
A. People mistakenly think they are experiencing seasonal allergies: While seasonal allergies may share some symptoms with the common cold, such as nasal congestion and sneezing, they are caused by allergens rather than viruses. This factor does not directly contribute to the high communicability of the common cold.
B. The virus is spread by individuals who don't have symptoms: The common cold is highly communicable because individuals infected with the virus can spread it to others even before they develop symptoms or when they have mild symptoms. This makes it challenging to prevent the spread of the virus, as infected individuals may not realize they are contagious.
C. Hand washing is not effective against the cold virus: Hand washing is an effective measure for preventing the spread of the common cold virus. Proper hand hygiene can help reduce the transmission of the virus from contaminated surfaces to the nose and mouth.
D. Use of over-the-counter cold products reduces immune resistance: Over-the-counter cold products may help relieve symptoms of the common cold but do not directly affect immune resistance. However, reliance on symptomatic relief without taking precautions to prevent the spread of the virus can contribute to its communicability.
