The nurse is preparing an older client for a magnetic resonance imaging (MRI) with contrast. Which laboratory value should the nurse report to the healthcare provider before the scan is performed?

Reference Range:
Glycosylated hemoglobin (A1C) [4% to 5.9%]
Creatinine [0.5 to 1.1 mg/dL (44 to 97 umol/L)]
Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)]
Blood Urea Nitrogen (BUN) [10 to 20 mg/dL (3.6 to 7.1 mmol/L)]

a) Denies cramps, weakness, or nausea

This finding indicates that the actions taken were effective in relieving the patient's symptoms of fatigue, weakness, muscle cramps, and nausea. These symptoms may have been caused by electrolyte imbalances, dehydration, or infection related to her ESRD and missed dialysis sessions.

b) BP 116/68 mm Hg, HR 75 bpm

This finding indicates that the actions taken were effective in lowering the patient's blood pressure and heart rate. The patient had a history of HTN and CAD and presented with elevated BP and HR in the ED. The orders for EKG, cardiac monitor, chest X-ray, and echocardiogram may have helped to assess and manage her cardiac status. The patient may have also received antihypertensive medications or fluids as part of her treatment.

c) Potassium level 3.6 mEq/L (3.6 mmol/L)

This finding indicates that the actions taken were effective in normalizing the patient's potassium level. The patient had ESRD and missed dialysis sessions, which could have resulted in hyperkalemia or hypokalemia. The orders for basic metabolic panel and blood cultures may have helped to monitor and correct her electrolyte levels. The patient may have also received potassium supplements or binders as part of her treatment.

d) Verbalizes commitment to dialysis appointments

This finding indicates that the actions taken were effective in educating and motivating the patient to adhere to her dialysis schedule. The patient had ESRD and missed dialysis sessions, which could have worsened her condition and increased her risk of complications. The orders for CT scan of abdomen and echocardiogram may have helped to evaluate her renal function and cardiac function. The patient may have also received counseling or support from the health care team as part of her treatment.

e) Client states that she will need to resume her Lisinopril to control blood pressure

This finding indicates that the actions taken were ineffective in teaching the patient about her medication regimen. The patient had a history of HTN and CAD and was prescribed Lisinopril as an antihypertensive medication. However, Lisinopril is contraindicated in patients with ESRD as it can cause hyperkalemia or worsen renal function. The patient should be informed about the potential risks of taking Lisinopril and advised to consult with her nephrologist or primary care provider before resuming it.

f) Client is eager to add dark green vegetables and potatoes to her diet

This finding indicates that the actions taken were ineffective in educating the patient about her dietary restrictions. The patient had ESRD and required hemodialysis three times a week. She should follow a renal diet that limits the intake of potassium, phosphorus, sodium, and fluid. Dark green vegetables and potatoes are high in potassium and phosphorus and should be avoided or consumed in moderation by patients with ESRD. The patient should be provided with a list of foods that are suitable for her condition and referred to a dietitian for further guidance.

Choice A reason: Potassium 4.7 mEq/L (4.70 mmol/L) is within the normal reference range of 3.5 to 5 mEq/L (3.5 to 5 mmol/L). Potassium is an electrolyte that helps regulate the balance of fluids and acids in the body, as well as the function of nerves and muscles. A high potassium level (hyperkalemia) can cause muscle weakness, irregular heartbeat, and cardiac arrest. A low potassium level (hypokalemia) can cause muscle cramps, fatigue, and arrhythmias.

Choice B reason: Magnesium 2.1 mEq/L (0.86 mmol/L) is within the normal reference range of 1.3 to 2.1 mEq/L (0.65 to 1.05 mmol/L). Magnesium is an electrolyte that helps regulate the activity of enzymes, muscles, and nerves, as well as the balance of calcium and potassium in the body. A high magnesium level (hypermagnesemia) can cause nausea, vomiting, flushing, muscle weakness, and respiratory depression. A low magnesium level (hypomagnesemia) can cause muscle twitching, tremors, seizures, and cardiac arrhythmias.

Choice C reason: Calcium 6.5 mg/dL (1.63 mmol/L) is below the normal reference range of 9 to 10.5 mg/dL (2.3 to 2.6 mmol/L). Calcium is an electrolyte that helps regulate the function of muscles, nerves, bones, and blood clotting. A high calcium level (hypercalcemia) can cause nausea, vomiting, constipation, confusion, kidney stones, and bone pain. A low calcium level (hypocalcemia) can cause muscle spasms, cramps, tingling, numbness, and stridor (a high-pitched sound when breathing). **This is a critical value that should be immediately reported to the healthcare provider**, as it can indicate a serious condition such as acute pancreatitis, sepsis, or massive blood transfusion.

Choice D reason: Sodium 135 mEq/L (135 mmol/L) is slightly below the normal reference range of 136 to 145 mEq/L (136 to 145 mmol/L). Sodium is an electrolyte that helps regulate the balance of fluids and acids in the body, as well as the function of nerves and muscles. A high sodium level (hypernatremia) can cause thirst, dry mouth, confusion, seizures, and coma. A low sodium level (hyponatremia) can cause headache, nausea, vomiting, fatigue, muscle weakness, and confusion.
