A patient has a serum phosphate level of 2.0 mg/dL. Which treatments should the nurse expect to be prescribed for this patient? Select all that apply.
A. Normal saline.
Normal saline is not typically used to treat low phosphate levels. It is often used to treat dehydration and electrolyte imbalances that do not include hypophosphatemia.
B. Potassium phosphate.
Potassium phosphate is used to treat low phosphate levels. It directly supplements phosphate levels in the body, making it an appropriate treatment for hypophosphatemia.
C. Additional milk intake.
Additional milk intake can help increase phosphate levels, as milk is a good source of phosphate. This is a suitable recommendation for a patient with low phosphate levels.
D. Increased Vitamin D intake.
Increased Vitamin D intake can enhance phosphate absorption from the gastrointestinal tract, making it a beneficial treatment for a patient with low phosphate levels.

A nurse is caring for a client whose arterial blood gas results show a pH of 7.3 and a Paco2 of 50 mm Hg. The nurse should identify that the client is experiencing which of the following acid-base imbalances?
A. Respiratory acidosis.
The arterial blood gas results show a low pH (acidosis) and an elevated Paco2 (partial pressure of carbon dioxide), which indicates respiratory acidosis. This condition occurs when there is inadequate removal of carbon dioxide through ventilation, leading to an accumulation of carbonic acid in the blood and a decrease in pH.
B. Metabolic acidosis.
Metabolic acidosis would present with a low pH and a low bicarbonate (HCO3-) level, not an elevated Paco2.
C. Metabolic alkalosis.
Metabolic alkalosis would present with a high pH and an elevated bicarbonate (HCO3-) level, not an elevated Paco2.
D. Respiratory alkalosis.
Respiratory alkalosis would present with a high pH and a decreased Paco2, not an elevated Paco2 as seen in this case.
Full Explanation
Choice A rationale:
The arterial blood gas results show a low pH (acidosis) and an elevated Paco2 (partial pressure of carbon dioxide), which indicates respiratory acidosis. This condition occurs when there is inadequate removal of carbon dioxide through ventilation, leading to an accumulation of carbonic acid in the blood and a decrease in pH.
Choice B rationale:
Metabolic acidosis would present with a low pH and a low bicarbonate (HCO3-) level, not an elevated Paco2.
Choice C rationale:
Metabolic alkalosis would present with a high pH and an elevated bicarbonate (HCO3-) level, not an elevated Paco2.
Choice D rationale:
Respiratory alkalosis would present with a high pH and a decreased Paco2, not an elevated Paco2 as seen in this case.
A nurse is reviewing the laboratory results of a client who is dehydrated. Which of the following BUN lab values should the nurse report to the provider?
A. 10 mg/dL.
A BUN (Blood Urea Nitrogen) level of 10 mg/dL is within the normal range, indicating normal kidney function. There is no indication to report this value to the provider for a dehydrated client.
B. 18 mg/dL.
A BUN level of 18 mg/dL is within the normal range as well. This value does not suggest significant dehydration, so it is not necessary to report it to the provider in this context.
C. 13 mg/dL.
A BUN level of 13 mg/dL is also within the normal range, and similar to choices A and B, it does not indicate severe dehydration that requires immediate reporting to the provider.
D. 25 mg/dL.
A BUN level of 25 mg/dL is elevated, which may indicate dehydration, kidney dysfunction, or other issues affecting fluid balance. Since the client is dehydrated, this elevated value needs to be reported to the provider for further evaluation and appropriate intervention.
Full Explanation
25 mg/dL.
Choice A rationale:
A BUN (Blood Urea Nitrogen) level of 10 mg/dL is within the normal range, indicating normal kidney function. There is no indication to report this value to the provider for a dehydrated client.
Choice B rationale:
A BUN level of 18 mg/dL is within the normal range as well. This value does not suggest significant dehydration, so it is not necessary to report it to the provider in this context.
Choice C rationale:
A BUN level of 13 mg/dL is also within the normal range, and similar to choices A and B, it does not indicate severe dehydration that requires immediate reporting to the provider.
Choice D rationale:
A BUN level of 25 mg/dL is elevated, which may indicate dehydration, kidney dysfunction, or other issues affecting fluid balance. Since the client is dehydrated, this elevated value needs to be reported to the provider for further evaluation and appropriate intervention.
A patient with fluid overload is prescribed furosemide (Lasix) 20 mg by mouth each day. What should the nurse include when teaching the patient about this medication? Select all that apply.
A. Expect urination to increase.
Furosemide is a loop diuretic that promotes diuresis, causing an increase in urine output. It is essential for the patient to expect this effect and understand that it helps in reducing fluid overload.
B. Expect to feel weak and dizzy.
Feeling weak and dizzy is not an expected effect of furosemide. It is more commonly associated with dehydration or excessive fluid loss, which can occur if the medication causes too much diuresis.
C. Take the medication before going to sleep.
Taking furosemide before going to sleep is not recommended because it can lead to nighttime diuresis, disrupting sleep and potentially causing electrolyte imbalances.
D. Report swelling of the face or hands.
Swelling of the face or hands may indicate an adverse reaction to furosemide or an underlying medical issue. The nurse should instruct the patient to report any such symptoms promptly.
E. Monitor body weight daily.
Monitoring body weight daily is crucial for patients on diuretic therapy to assess fluid status and response to treatment. Rapid weight gain may indicate worsening fluid overload, while significant weight loss may indicate excessive diuresis.
