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?
Romaine lettuce.
Lean red meat.
Almonds.
White rice.
Correct Answer : A,C
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 A
Explanation
Choice A rationale:
The client with a phosphate level of 5.7 mg/dL likely has a manifestation of hypoparathyroidism. Hypoparathyroidism leads to decreased parathyroid hormone (PTH) secretion, which causes increased renal phosphate reabsorption, leading to elevated phosphate levels in the blood.
Choice B rationale:
A calcium level of 9.8 mg/dL is within the normal range (8.5-10.2 mg/dL) and does not indicate hypoparathyroidism.
Choice C rationale:
A vitamin D level of 25 ng/mL is within the normal range (30-100 ng/mL) and does not suggest hypoparathyroidism.
Choice D rationale:
A magnesium level of 1.8 mEq/L is within the normal range (1.7-2.2 mEq/L) and does not directly indicate hypoparathyroidism.
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.
