The nurse is caring for four clients: Client A, who has emphysema and whose oxygen saturation is 94%; Client B, with a postoperative hemoglobin of 8.2 mg/dL (82 g/L); Client C, newly admitted with a potassium level of 3.8 mEq/L (3.8 mmol/L); and Client D, scheduled for an appendectomy who has a white blood cell (WBC) count of 14,000 mm (14 x 10^9/L). Which intervention should the nurse implement? Reference Range:. Hemoglobin [14 to 18 g/dL (140 to 180 g/L)]. Potassium [3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)]. White Blood Cell [5000 to 10,000/mm² (5 to 10 x 10^9/L)].

The observation(s) by the nurse that require immediate intervention to reduce the likelihood of harm to this client are:

A. The client’s oxygen saturation level is 85%. This is a sign of hypoxemia, which can lead to tissue hypoxia, organ damage, and cardiac arrest. The nurse should administer oxygen therapy and monitor the client’s respiratory status closely.

C. The client’s heart rate is 110 beats per minute. This is a sign of tachycardia, which can indicate worsening heart failure, dehydration, infection, or anxiety. The nurse should assess the client’s fluid balance, vital signs, and symptoms and report any changes to the physician. The nurse should also administer medications as prescribed to control the heart rate and reduce the cardiac workload.

E. The client’s blood pressure is 160/90 mmHg. This is a sign of hypertension, which can increase the risk of stroke, myocardial infarction, and renal failure. The nurse should administer antihypertensive medications as prescribed and monitor the client’s blood pressure and urine output. The nurse should also educate the client on lifestyle modifications to lower blood pressure, such as reducing salt intake, exercising, and managing stress .

The other observations do not require immediate intervention, but they should be addressed as part of the comprehensive nursing care plan for the client with heart failure and COPD. These include:

B. The client is eating less than half of meals. This can indicate poor appetite, nausea, dyspnea, or fatigue, which can affect the client’s nutritional status and energy level. The nurse should encourage the client to eat small, frequent, and balanced meals that are low in sodium, fat, and cholesterol. The nurse should also provide oral hygiene and offer supplements or enteral feeding if needed .

D. The client is reading a book. This can indicate that the client is coping well with the condition and engaging in leisure activities that promote relaxation and mental health. The nurse should praise the client for this positive behavior and provide emotional support and counseling as needed. The nurse should also teach the client about the signs and symptoms of exacerbation and when to seek medical help .

When assessing an older client with left-sided heart failure (HF), the most important intervention for the practical nurse (PN) to implement is to auscultate all lung fields. Left-sided heart failure is characterized by the inability of the left ventricle to effectively pump blood, leading to fluid accumulation in the lungs. Auscultating all lung fields allows the PN to assess for the presence of abnormal lung sounds such as crackles, indicating pulmonary congestion.

Let's evaluate the other options:

a) Inspect for sacral edema.
Sacral edema is commonly associated with right-sided heart failure, not left-sided heart failure. While it is important to assess for edema in clients with heart failure, inspecting for sacral edema may not be the most immediate and crucial intervention in this specific case.

b) Measure urinary output.
Measuring urinary output is a valuable assessment in many clinical situations, but it may not be the most vital intervention in the context of left-sided heart failure. Monitoring urinary output is more relevant in assessing kidney function and fluid balance rather than directly assessing the severity of left-sided heart failure.

d) Check mental acuity.
Checking mental acuity is important in assessing the overall condition of the client, but it is not the most crucial intervention specifically related to left-sided heart failure. Mental status evaluation is more useful in identifying signs of altered mental status or potential complications, rather than directly assessing the impact of left-sided heart failure.

In summary, when assessing an older client with left-sided heart failure, the most important intervention for the practical nurse (PN) to implement is to auscultate all lung fields. This allows for the detection of abnormal lung sounds associated with pulmonary congestion, a hallmark sign of left-sided heart failure.
