1. Hematuria.
2. Hypertension.
3. Hyperkalemia.
4. Hypoglycemia. Answer: A
Explanation: Following a renal biopsy, the NP should monitor for complications such as hematuria, which is the presence of blood in the urine. Hematuria is a common complication of renal biopsy and can range from mild to severe. Hypertension (B), hyperkalemia (C), and hypoglycemia (D) are not typically associated with renal biopsy complications.

ecrease the ultrafiltration rate. dminister a bolus of intravenous fluids.
crease the dialysate sodium concentration. dminister a vasopressor medication.
wer: A
anation: Hypotension is a common complication during hemodialysis e caused by rapid fluid removal (ultrafiltration) during the treatment. intervention should be to decrease the ultrafiltration rate to slow do luid removal and prevent further drops in blood pressure.

concentration (C) can be considered in some cases, but it is not the first-line intervention for hypotension during hemodialysis. Administering a vasopressor medication (D) may be necessary in severe cases, but it is not the initial intervention and should be reserved for refractory hypotension.
Question: 4
A patient with chronic kidney disease (CKD) is at increased risk for cardiovascular disease. Which of the following interventions should the NP prioritize to reduce the patient's cardiovascular risk?
1. Blood pressure control.
2. Lipid-lowering therapy.
3. Smoking cessation.
wer: A
anation: Blood pressure control is a critical intervention to reduce the ovascular risk in patients with CKD. Hypertension is a common orbidity in CKD and a significant risk factor for cardiovascular diseas efore, achieving and maintaining optimal blood pressure control is a ity. Lipid-lowering therapy (B) may also be indicated if the patient ha pidemia. Smoking cessation (C) is important for overall cardiovascula h but is not specific to CKD. Diabetes management (D) is crucial for nts with CKD and coexisting diabetes, but it may not be applicable to
patients.

Explanation: The Modification of Diet in Renal Disease (MDRD) equation is commonly used to estimate glomerular filtration rate (eGFR) in adults. The Cockcroft-Gault equation is used to estimate creatinine clearance, the Schwartz equation is used to estimate GFR in children, and the DuBois formula is used to estimate body surface area.

for a patient with chronic kidney disease (CKD) and multiple risk factors for cardiovascular disease. Statins help to reduce cholesterol levels and decrease the risk of cardiovascular eventsin CKD patients. Initiating antiplatelet therapy, administering anticoagulants, and recommending coronary artery bypass graft (CABG) surgery may be considered in specific cases but are not the initial interventions for CKD patients with multiple risk factors for cardiovascular disease.

1. Presence of hyperkalemia.
2. Persistent oliguria.
3. Rapidly deteriorating kidney function.
4. Mild proteinuria. Answer: D
Explanation: When determining the need for initiation of acute kidney replacement therapy, factors such as the presence of hyperkalemia (high potassium levels), persistent oliguria (low urine output), and rapidly deteriorating kidney function are considered. However, the presence of mild proteinuria alone is not typically a sole determinant for initiating acute kidney replacement therapy.

anation: Elevated levels of urinary sodium and potassium would be istent with acute kidney injury (AKI). In AKI, the kidneys are unable erly regulate the excretion of sodium and potassium, leading to their mulation in the urine.

Explanation: A significant rise in serum creatinine levels can indicate acute kidney injury (AKI). One of the causes of AKI is drug-induced nephrotoxicity. Third-generation cephalosporins have been associated with nephrotoxic effects, and their use should be evaluated in patients with an acute rise in serum creatinine. Calcium channel blockers (A) and angiotensin-converting enzyme inhibitors (B) are not typically associated with nephrotoxicity. Macrolide antibiotics (C) generally do not cause significant nephrotoxic effects.
