A patient with HIV-1 has experienced a sudden decline in health status accompanied by a significant increase in viral load. What is the first action the nurse should take?

Rationale for Choice A:
Documentation is essential for communication and continuity of care, but it is not the most immediate priority in this situation.
The nurse should document the episode of vomiting, including the time, amount, and characteristics of the vomitus, as well as any associated symptoms or interventions.
However, auscultating lung sounds should be done first to assess for potential aspiration, which is a more urgent concern.
Rationale for Choice B:
Offering dry toast may be appropriate after the nurse has assessed for aspiration and determined that it is safe for the client to resume oral intake.
However, it is not the most important action at this time.
The nurse should first assess the client's respiratory status and address any potential complications.
Rationale for Choice C:
Rest is important for healing and recovery, but it is not the most immediate priority in this situation. The nurse should first assess the client's respiratory status and address any potential complications. Once the client is stable, the nurse can then encourage rest.
Rationale for Choice D:
Auscultating lung sounds is the most important action for the nurse to take after a client vomits.
This is because aspiration of vomitus is a serious complication that can lead to pneumonia, respiratory distress, and even death.
By auscultating lung sounds, the nurse can assess for signs of aspiration, such as crackles, wheezing, or diminished breath sounds.
If aspiration is suspected, the nurse can initiate appropriate interventions, such as suctioning, oxygen therapy, and positioning the client to facilitate drainage of secretions.

Rationale for A: Hemoglobin and Hematocrit
Hemoglobin (Hgb) of 6.8 g/dL is significantly below the normal range of 12-16 g/dL for women and 14-18 g/dL for men. This indicates severe anemia, which can cause several of the patient's reported symptoms, including shortness of breath, fatigue, dizziness, and intolerance to cold. It's crucial to address this promptly as severe anemia can lead to tissue hypoxia and organ damage.
Hematocrit (Hct) of 21.2% is also below the normal range of 36-46% for women and 41-50% for men. Hct measures the percentage of red blood cells in the blood, and its low value further confirms the presence of anemia.

Rationale for B: Blood Pressure 100/68, Respirations 24
Blood pressure of 100/68 mmHg is considered low, especially in a patient with a history of hypertension. This could be due to the anemia, as low red blood cell count can decrease blood volume and subsequently lower blood pressure. It's essential to monitor the patient's blood pressure closely, as hypotension can lead to dizziness, fainting, and even shock.
Respirations of 24 breaths per minute are slightly elevated above the normal adult range of 12-20 breaths per minute. This could be a compensatory mechanism for the anemia, as the body tries to increase oxygen intake. However, it could also indicate other underlying respiratory issues that need to be investigated.

Rationale for F: Shortness of breath with exertion
Shortness of breath (dyspnea) is a common symptom of anemia, as the body struggles to deliver enough oxygen to tissues during physical activity. This symptom warrants immediate attention, as it can significantly impact the patient's quality of life and could potentially signal worsening anemia or other cardiopulmonary problems.

Rationale for G: Dizziness when standing
Dizziness upon standing (orthostatic hypotension) is a sign of low blood pressure, which can be exacerbated by anemia. This can increase the risk of falls and injuries, especially in a patient with other health conditions. It's crucial to address this symptom to prevent potential complications.
