A nurse is reviewing the laboratory results of a client who takes furosemide. Which of the following results should the nurse identify as the priority finding?

Phosphorus 4.5 mEq/L.

Potassium 2.9 mEq/L.

Calcium 8.2 mg/dL.

Sodium 145 mEq/L.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

A phosphorus level of 4.5 mEq/L falls within the normal range, which is typically between 2.5 to 4.5 mEq/L. Although it's essential to monitor phosphorus levels, it is not the priority finding in this scenario.

Choice B rationale:

A potassium level of 2.9 mEq/L is the priority finding. The normal range for potassium is typically between 3.5 to 5.0 mEq/L. A potassium level of 2.9 mEq/L indicates severe hypokalemia, which can lead to life-threatening cardiac arrhythmias and muscle weakness. Immediate intervention is necessary to address the potassium imbalance.

Choice C rationale:

A calcium level of 8.2 mg/dL falls within the normal range (typically 8.5 to 10.2 mg/dL). While calcium levels are essential to monitor, they do not take precedence over the critically low potassium level in this situation.

Choice D rationale:

A sodium level of 145 mEq/L falls within the normal range, which is usually around 135 to 145 mEq/L. Although monitoring sodium levels is important, it is not the priority finding when compared to the critically low potassium level.

Correct Answer is D

Explanation

The correct answer is choice D: Reduction of T-wave amplitude.

Choice A rationale:

The amplitude of the QRS complex is not directly affected by changes in serum potassium levels. It represents ventricular depolarization, and its restoration would not be an expected outcome of polystyrene sulfonate treatment

Choice B rationale:

Shortening of the P-wave duration is not an expected change with polystyrene sulfonate treatment. The P-wave represents atrial depolarization, which is not significantly impacted by the administration of this medication

Choice C rationale:

Widening of the QRS complex is associated with high serum potassium levels. The goal of polystyrene sulfonate treatment is to lower potassium levels and, thus, return the QRS complex to its normal width

Choice D rationale:

Polystyrene sulfonate aims to reduce serum potassium levels. When effective, this should result in a reduction of T-wave amplitude, which is a common ECG change seen with hyperkalemia

In conclusion, choice D is the correct answer, as a reduction in T-wave amplitude would be the expected change on the client's ECG if polystyrene sulfonate effectively lowers their serum potassium level.

A. Romaine lettuce. B. Lean red meat. C. Almonds. D. White rice.

Correct Answer is ["A","C"]

Explanation

Choice A rationale:

Romaine lettuce is a good dietary source of magnesium. Since the patient has a low serum magnesium level, suggesting foods rich in magnesium like romaine lettuce can help improve magnesium levels.

Choice B rationale:

Lean red meat is not a good suggestion for a patient with low magnesium levels. While it contains magnesium, it is not as rich in magnesium as some other food choices.

Choice C rationale:

Almonds are a good dietary source of magnesium and can be recommended to the patient with low magnesium levels to help increase their magnesium intake.

Choice D rationale:

White rice is not a significant source of magnesium and may not be helpful in improving the patient's low magnesium levels.

Choice E rationale:

Seafood is a good source of various nutrients but is not particularly rich in magnesium compared to other options like almonds and romaine lettuce. Thus, it may not be the best suggestion for the patient's low magnesium levels.

Correct Answer is D

Explanation

The patient who has a serum magnesium level of 1.4 mg/dL is being treated with dietary modification. Which foods should the nurse suggest for this patient?

Correct Answer is ["A","C"]

Explanation

A client is admitted to the emergency room with a respiratory rate of 7/min. Arterial blood gases (ABG) reveal the following values. Which of the following is an appropriate analysis of the ABGs? pH 7.22, PacO₂ 68 mm Hg, Base excess -2, PaO₂ 78 mm Hg, Saturation 80%, Bicarbonate 26 mEq/L.
