What condition do these results indicate? A nurse is reviewing arterial blood gas lab values on her newly admitted elderly client. The ABG results are as follows: pH 7.21, PaCO2 50, HCO3 26.

Respiratoty acidosis

Metabolic alkalosis

Respiratory alkalosis

Metabolic acidosis

Answer and Explanation

The Correct Answer is A

A) Respiratory acidosis:
This condition is characterized by an increase in PaCO2 and a decrease in pH, which is exactly what is seen in these ABG results. The pH of 7.21 indicates acidosis (normal pH range is 7.35–7.45), and the PaCO2 of 50 is elevated (normal PaCO2 range is 35–45 mmHg), indicating that carbon dioxide retention is contributing to the acidosis. In respiratory acidosis, the lungs are unable to adequately expel CO2, leading to an accumulation of CO2 in the blood, which decreases the pH. The HCO3 (bicarbonate) is within normal range (22–28 mEq/L), suggesting that there has not yet been compensation by the kidneys, which would typically increase bicarbonate levels to buffer the acidosis.

B) Metabolic alkalosis:
Metabolic alkalosis is characterized by an elevated pH (above 7.45) and an elevated HCO3 (above 28 mEq/L). In this case, the pH is low (7.21), and the bicarbonate level (HCO3) is normal (26), so metabolic alkalosis is not the correct diagnosis.

C) Respiratory alkalosis:
Respiratory alkalosis occurs when there is decreased PaCO2 (below 35 mmHg) and an elevated pH (above 7.45), typically due to hyperventilation. Since the PaCO2 is elevated (50 mmHg) in this case, it rules out respiratory alkalosis.

D) Metabolic acidosis:
Metabolic acidosis is characterized by a low pH (below 7.35) and a low HCO3 (below 22 mEq/L). While the pH is low in this case, the HCO3 is normal (26 mEq/L), which suggests that the acidosis is not metabolic in origin. Metabolic acidosis would typically show a low bicarbonate level, indicating that the kidneys are not able to compensate effectively.

Correct Answer is A

Explanation

A) The UAP stands by the patient's bed for 60 minutes talking with the patient:
This action requires immediate intervention because of the potential radiation exposure to the UAP. A temporary radioactive cervical implant involves placing a radioactive source in or near the patient's cervix. This implant emits radiation, and safety precautions are essential to limit exposure to others, including healthcare workers. Prolonged close contact, such as standing by the patient's bed for 60 minutes, increases the risk of radiation exposure to the UAP.

B) The UAP gives the patient a saline mouthwash to use for oral care:
There are no specific contraindications to using a saline mouthwash for oral care in patients with a radioactive implant. Saline mouthwash is commonly recommended for patients undergoing radiation therapy to soothe the mouth and prevent dryness or irritation. As long as the UAP is following standard infection control and safety precautions.

C) The UAP places the patient's bedding in the laundry container inside the client's room:
Bedding and linens from a patient with a radioactive implant can usually be handled and disposed of according to hospital guidelines for radioactive waste. Often, these linens are not considered to pose a significant radiation hazard after removal from the patient’s immediate area, especially if the patient is not emitting radiation outside the prescribed safety guidelines.

D) The UAP flushes the toilet twice after emptying the patient's bedpan:
After the patient has a radioactive implant, any bodily waste (urine, stool) can potentially contain small amounts of radiation. Flushing the toilet twice helps to ensure that any radioactive materials are effectively cleared. However, the UAP should be instructed to wear gloves and take other precautions to prevent contamination while handling the bedpan and ensuring proper disposal of waste.

A. Use a razor to shave the hair in the treated area. B. Wash treated area gently with lukewarm water and mild soap. C. Purchase aloe approved skin-care products D. Wear loose-fitting, soft clothing over the treated skin. E. Sun tan the affected area for no more than 30 minutes a day

Correct Answer is ["B","C","D"]

Explanation

A) Use a razor to shave the hair in the treated area:
Shaving the treated area with a razor is not recommended during radiation therapy. The skin in the treated area becomes sensitive and fragile, so shaving could cause irritation, cuts, or abrasions. Instead, clients are usually advised to use electric razors or avoid shaving the area altogether. This instruction should not be followed to minimize the risk of injury.

B) Wash treated area gently with lukewarm water and mild soap:
This is a key self-care instruction for clients receiving radiation. Gentle cleansing with lukewarm water and mild soap helps to avoid further irritation to the skin, which can become dry and sensitive during radiation therapy. The treated area should not be scrubbed or rubbed, as this can cause damage to the skin, exacerbate dryness, or cause skin breakdown. This guideline is appropriate and should be followed.

C) Purchase aloe-approved skin-care products:
Using aloe vera or skin-care products approved for use during radiation therapy can help soothe and moisturize the skin, which often becomes dry, irritated, or sunburned from radiation. It is important to use products that are specifically designed for use during radiation to avoid any potential irritants or allergens. Aloe-based products or products recommended by the healthcare provider can provide relief and reduce side effects.

D) Wear loose-fitting, soft clothing over the treated skin:
Wearing loose-fitting, soft clothing is a crucial self-care recommendation for clients undergoing radiation. Tight or rough fabrics can irritate the sensitive skin, potentially leading to discomfort or skin breakdown. Soft fabrics like cotton are ideal, as they allow the skin to breathe and help avoid further friction or pressure on the treated area. This is an important aspect of skin protection during radiation therapy.

E) Sun tan the affected area for no more than 30 minutes a day:
Sun tanning or exposing the treated skin to direct sunlight is strictly forbidden during and after radiation therapy. The skin in the treated area is much more sensitive to UV radiation and can burn easily, even with minimal sun exposure. It can increase the risk of skin damage and delayed healing. The client should be advised to avoid direct sun exposure entirely and to wear protective clothing and sunscreen if they must be outdoors.
