A client's PaCO2 is abnormal on an ABG report.
What does the nurse suspect as the most likely medical diagnosis?
Sexually Transmitted Infection (STI).
Chronic Obstructive Pulmonary Disease (COPD).
Congestive Heart Failure (CHF).
Chronic Renal Insufficiency or Failure (CRF).
The Correct Answer is B
Choice A rationale
Sexually Transmitted Infections (STIs) primarily affect the reproductive system and do not directly cause abnormalities in PaCO2 levels. PaCO2 reflects the partial pressure of carbon dioxide in arterial blood, which is a key indicator of respiratory function and acid-base balance.
Choice B rationale
Chronic Obstructive Pulmonary Disease (COPD) is a group of lung diseases that obstruct airflow, leading to impaired gas exchange. This impaired exchange often results in the retention of carbon dioxide, causing an elevated PaCO2 level on an ABG report, indicating respiratory acidosis.
Choice C rationale
Congestive Heart Failure (CHF) primarily affects the cardiovascular system, leading to fluid overload and potential pulmonary congestion. While severe CHF can indirectly affect gas exchange, the most direct and common cause of abnormal PaCO2 is a respiratory issue like COPD.
Choice D rationale
Chronic Renal Insufficiency or Failure (CRF) primarily affects the kidneys' ability to regulate electrolytes and waste products. While CRF can lead to metabolic acidosis, which can trigger respiratory compensation (altering PaCO2), it is not the most direct or likely cause of an abnormal PaCO2 level on an ABG report.

Correct Answer is D
Explanation
Choice A rationale
Discouraging the family from talking about death can hinder their grieving process and may prevent the dying client from having important conversations and finding closure. Open communication about death and dying is often therapeutic for both the client and their family members, allowing them to express emotions and support each other.
Choice B rationale
Informing the family that the client may soon be out of danger when the client is actively dying of renal failure is providing false reassurance and can erode trust between the nurse and the family. It is crucial to be honest and compassionate about the client's prognosis, preparing the family for the impending death rather than offering false hope.
Choice C rationale
While rest is important for a dying client, encouraging the family to leave the client alone may deprive both the client and the family of valuable time for connection and saying goodbye. The presence and support of loved ones can provide comfort to the dying person and begin the grieving process for the family.
Choice D rationale
Informing the family that it is time to bid farewell acknowledges the reality of the situation and provides an opportunity for the family to express their love, say their goodbyes, and find closure. This supportive action respects the dying process and the emotional needs of the family members as they face the imminent loss of their loved one. .
Correct Answer is B
Explanation
Choice A rationale
Vitamin C is an important antioxidant and plays a role in collagen synthesis and immune function. While individuals with alcoholism may have poor nutrition and potential vitamin deficiencies, thiamine (vitamin B1) deficiency is a more immediate and critical concern due to its role in glucose metabolism and the risk of Wernicke-Korsakoff syndrome.
Choice B rationale
Thiamine deficiency is common in individuals with chronic alcoholism due to poor dietary intake, impaired absorption, and increased utilization of thiamine in metabolizing alcohol. Intramuscular administration ensures adequate absorption, and the frequency addresses the ongoing need to prevent or treat Wernicke-Korsakoff syndrome, a serious neurological disorder.
Choice C rationale
Magnesium deficiency is also common in alcoholics due to poor intake, increased urinary excretion, and gastrointestinal losses. While a one-time intravenous dose of magnesium sulfate can help replete levels and prevent complications like seizures, it does not address the chronic nature of the deficiency and the need for ongoing management.
Choice D rationale
Albumin is a plasma protein that can be low in individuals with chronic liver disease, which can be associated with alcoholism. However, a one-time infusion of albumin primarily addresses low oncotic pressure and fluid shifts and is not a standard initial treatment for alcoholism itself. Addressing thiamine deficiency is a more immediate priority to prevent neurological complications.
