A 9-year-old girl being treated with combination chemotherapy for acute lymphoblastic leukemia (ALL) is noted to have increased levels of blood urea nitrogen (BUN) and creatinine on day 4 of treatment. The patient is immediately started on intravenous normal saline. An ECG is ordered which demonstrates prolonged QT intervals. For confirmation of the diagnosis, several laboratory tests, including a complete metabolic profile, are ordered. Which of the following laboratory abnormalities result from this patient's condition?

Sodium 136 mEq/LPotassium 2.6 mEq/LChloride 93 mEq/LBicarbonate 34 mEq/LBlood urea nitrogen 9 mg/dLCreatinine 0.8 mg/dLGlucose 150 mg/dL (non-fasting)Magnesium 0.6 mEq/L Arterial blood gas  pH 7.50  PaO2 95 mmHg  PaCO2 48 mmHg Urine studies show high levels of potassium and chloride, and low levels of calcium. Which of the following conditions would produce similar findings to this patient's disease?

The nurse identifies which of the following diagnostic laboratory tests as the one the nurse should assess first to establish a diagnosis for renal disease? A. Blood urea nitrogen (BUN) B. Serum creatinine C. Serum uric acid D. Serum potassium

A 68-year-old man comes to the physician for a follow-up examination. He has type 2 diabetes mellitus, hypertension, and chronic kidney disease. Medications include insulin, metoprolol, and atorvastatin. Physical examination shows pitting edema of both ankles. Serum creatinine concentration is 4.5 mg/dL. Which of the following sets of serum findings is most likely in this patient?Parathyroid hormone (PTH) Vitamin D Calcium PhosphorusA Decreased increased increased increasedB Increased decreased decreased increasedC Increased decreased increased decreasedD Increased decreased decreased decreasedE Decreased decreased decreased increased

A 62-year-old man with a history of congestive heart failure (CHF) presents with confusion, nausea, and vomiting. Physical examination reveals peripheral edema, bibasilar crackles, and jugular venous distention. The patient is found to have a sodium level of 112 mEq/L. The physician places the patient on free water restriction. Which of the following laboratory values do you expect with respect to the fractional excretion of sodium (FENa) and urine sodium (UNa) with this condition? FENa UNa(A) >1% <10 mEq/L(B) >1% >20 mEq/L(C) <1% <10 mEq/L(D) <1% >20 mEq/L

A 29-year-old man is diagnosed with testicular cancer and undergoes orchiectomy. He is followed afterward, and the cancer recurs. He elects to undergo treatment with bleomycin, etoposide, and cisplatin for four cycles. Several months after finishing chemotherapy, he returns for follow-up. On examination, he has bilateral dry crackles over both lung fields. His laboratory values are significant for a hemoglobin of 9.4 g/dL and a creatinine of 2.4 mg/dL (baseline 1.1 mg/dL). Which of the following is most likely responsible for the lung findings on examination?Ask StudybuddyGroup of answer choicesCisplatinBleomycinEtoposideTumor metastases
