A nurse is caring for a client with diabetes insipidus (DI). Which data warrants the most immediate intervention by the nurse?
Reference Range: Sodium 136 to 145 mEq/L (136 to 145 mmol/L)

Choice A reason: Distinguishing the difference between herpes varicella and herpes zoster is important for client education. Herpes varicella (chickenpox) and herpes zoster (shingles) are caused by the same virus, the varicella-zoster virus (VZV). After a person recovers from chickenpox, the virus remains dormant in the nerve tissues and can reactivate years later as shingles. Educating the client about the relationship between these two conditions helps in understanding the risk and nature of shingles.

Choice B reason: Explaining that the risk of developing shingles decreases with age is incorrect. In fact, the risk of developing shingles increases with age, especially in individuals over 50. The immune system's ability to keep the varicella-zoster virus dormant decreases with age, leading to a higher likelihood of reactivation as shingles. Therefore, this choice is not appropriate for client education.

Choice C reason: Affirming that a person with shingles has a history of chickenpox infection is accurate. Shingles occurs when the dormant varicella-zoster virus reactivates in someone who has previously had chickenpox. This information helps the client understand the connection between past chickenpox infection and the potential for developing shingles.

Choice D reason: Asking the client to describe the type of shingles that her brother has is not relevant to the client's own risk or education about shingles. The focus should be on providing accurate information about shingles and its relation to chickenpox, not on the details of another person's condition.

Choice E reason: Instructing the client to report the development of fatigue and low-grade fever is important because these can be early symptoms of shingles. Early identification and treatment of shingles can help manage symptoms and reduce complications. Educating the client on what to watch for and when to seek medical attention is crucial for effective management.

Temperature: 98.9°F

• Neither Disease Process Nor Medication Use:
  The temperature is within normal range and does not indicate an infection or other abnormality.

Heart Rate: 112 beats per minute

• Disease Process:
  The elevated heart rate (tachycardia) is most likely due to the asthma attack, which increases respiratory effort and oxygen demand. Anxiety from the attack could also contribute.

Respirations: 28 breaths per minute

• Disease Process:
  The elevated respiratory rate (tachypnea) is consistent with the asthma attack and respiratory distress, a hallmark of the disease process.

Blood Pressure: 130/86 mmHg

• Neither Disease Process Nor Medication Use:
  This value is slightly elevated but not significantly enough to be directly attributed to asthma or medication. It could be situational due to stress or anxiety.

Oxygen Saturation: 88%

• Disease Process:
  The low oxygen saturation is indicative of hypoxemia caused by bronchoconstriction and impaired gas exchange during the asthma attack.
