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 A
Explanation
Choice A rationale
Emptying a Foley catheter bag and reporting the urine volume is a routine task that does not require complex assessment or clinical judgment. Unlicensed care providers are typically trained in this procedure and can accurately measure and report the output to the nurse.
Choice B rationale
Helping a first-time mother achieve a good latch during breastfeeding requires specialized knowledge and assessment skills to ensure proper positioning and infant feeding. This task involves teaching and evaluating, which falls within the scope of nursing practice and should not be delegated to an unlicensed care provider.
Choice C rationale
Assessing the size and quantity of blood clots in a postpartum client's bedpan requires clinical judgment to determine if the findings are within normal limits or indicative of a potential complication. This assessment should be performed by a registered nurse who can interpret the findings in the context of the client's overall condition.
Choice D rationale
Administering medication, including anti-inflammatory drugs, is a nursing responsibility that requires knowledge of pharmacology, potential side effects, and client assessment. Medication administration should not be delegated to unlicensed care providers. .
Correct Answer is A
Explanation
Choice A rationale
Playing music chosen by the client can promote relaxation by providing a familiar and comforting auditory stimulus. Music can help to reduce anxiety and create a calming environment, thus minimizing sensory overload in a client recovering from a stroke in the intensive care unit. This personalized approach respects the client's preferences and can positively influence their emotional state, fostering a more restful atmosphere conducive to healing.
Choice B rationale
Encouraging frequent visitors throughout the day can contribute to sensory overload for a client recovering from a stroke. While social support is important, excessive stimulation from multiple visitors can be overwhelming and disrupt the client's rest and recovery process in the intensive care unit, potentially increasing agitation and hindering relaxation.
Choice C rationale
Sitting in a chair next to the client and talking can be stimulating and may not promote relaxation, especially for a client who has recently experienced a stroke. Depending on the content and tone of the conversation, this interaction could increase sensory input and potentially cause agitation or fatigue rather than fostering a calm and restful environment needed for recovery in the intensive care unit.
Choice D rationale
Turning on the television to the Super Bowl would likely exacerbate sensory overload due to the bright lights, loud noises, and fast-paced visual stimulation. This type of environment is counterproductive to promoting relaxation and can be particularly overwhelming for a client recovering from a stroke in the intensive care unit, potentially increasing anxiety and hindering rest.
