What is the purpose of each medication which has been prescribed for the patient? List
drug:nutrient (food:medication) interactions for each.
Lasix: increases excretion of sodium, potassium, magnesium, and calcium in urine-
natural licorice may counteract the drug; maintain diet high in these compounds (may
Lisinopril: ACE inhibitor, increases serum potassium levels-monitor hydration and fluid
intake as well as salt and potassium intake (may be sensitive to potassium levels)
Metoprolol: 𝛽-Adrenergic antagonist masks sympathetic signs of hypoglycemia-may
decrease insulin release (in response to hypoglycemia), watch BG levels
Renvela: phosphate binder (controls phosphate levels)- be careful with calcium
supplements to prevent secondary hyperparathyroidism
Zemplar: helps absorb calcium and helps with secondary hyperthyroidism- problems if
allergic to man-made vitamin D or if there are high levels of calcium in the blood
EPO: attends to anemia in patients- monitor iron status in patient!
Ferrlecit: helps with anemia- may cause hypotension, excessive iron, and benzyl alcohol
What is secondary hyperparathyroidism and why is this patient at risk? What are the
consequences and how is this managed medically? Nutritionally?
Secondary hyperthyroidism is a result of kidney malfunction/failure. When the patient’s
kidney cannot filter minerals (in the case of secondary hyperparathyroidism, calcium and
phosphorous, specifically) out of the blood properly, their levels shoot out of proportion.
Generally, in the body, low levels of phosphorous and calcium in the blood are ideal. In
secondary hyperparathyroidism, serum calcium levels are low while serum phosphorous
increases; this triggers the parathyroid hormone to increase, which then, in turn, increases
reabsorption of calcium. Since calcium levels are already low, the body takes calcium
from bones of the body; this also mobilizes phosphorous from the bone. Increased levels
of calcium and phosphorous from the bone, now in the bloodstream don’t necessarily
have anywhere to go, so they form crystals in the tissues of the body.
The patient is at risk of secondary hyperparathyroidism because she is in Stage 5 (the
final stage) of chronic kidney failure. This is irreversible and she has to depend on
dialysis for the rest of her life. Since her kidney cannot filter minerals properly, she is
definitively at risk for secondary hyperparathyroidism.
This condition is managed medically by frequent hemodialysis and is managed
nutritionally by controlling intake of calcium and phosphorous.
Assess the patient’s Kcal, protein, Phos, K, Na, and fluid intake recommendations.
Kcal: 2061 kcal (35 kcal/Kg IBW) IBW=105+(5 x 5)=130lbs=58.9Kg
Protein: 71g (1.2 g/Kg IBW)
Phos: 0.8-1.2 g/day
K: 2-3 g/day
Na: 2-3 g/day
Fluid: 750 ml (750-1000 ml/day urine output)
Evaluate the patient’s current dietary intake including the following points:
How does CN’s current intake compare to these recommendations?
Some of the patient’s food is high in phosphorous, which she should monitor more
closely. Although adequate calcium intake is required, she should be more careful when
Calculate a dietary pattern which would meet the recommendations for this patient and using
foods create a sample one day diet. Use table format and the handouts provided in class. This
part counts as your renal diet calculation in addition to your case study.
Protein: 17% of Kcal= 350 Kcal
Fat: <30% of Kcal= 618 Kcal
Carbohydrate: 53% of Kcal= 1092 Kcal

Write two PES statements - one in the clinical and one in the behavioral domain and provide an
intervention, monitoring, and evaluation plan for each.
(1) Altered GI function [NC-1.4] related to abnormal absorption of calcium and phosphorous
as evidence by kidney failure and hemodialysis.
(2) Self monitoring deficit [NB-1.4] related to insufficient diet as evidence by 24 hour
dietary intake log and medication needs.
(1) Take prescribed medications, monitor dietary choices (maintain low potassium and
phosphorous levels in diet).
(2) Watch diet! Educate patient on what to eat and what to avoid (avoid nuts and legumes,
eat plenty of fruits and vegetables!) and show her how her diet and the foods she chooses
affect her body physically.
(1) Watch lab results on all values listed above, test urine samples to keep patient on track;
hemodialysis every 2-3 days; monitor GI functioning.
(2) . Monitor medication intake and make sure dosages and utilizations are correct.
