RENAL: Ignatavicius Ch 68: Care of Patients with Acute Kidney Injury and Chronic Kidney Disease Flashcards
The nurse is assessing a client with a diagnosis of pre-renal acute kidney injury (AKI). Which condition would the nurse expect to find in the clients recent history?
a. Pyelonephritis
b. Myocardial infarction
c. Bladder cancer
d. Kidney stones
b. Myocardial infarction
Pre-renal causes of AKI are related to a decrease in perfusion, such as with a myocardial infarction. Pyelonephritis is an intrinsic or intrarenal cause of AKI related to kidney damage. Bladder cancer and kidney stones are post-renal causes of AKI related to urine flow obstruction.
A marathon runner comes into the clinic and states I have not urinated very much in the last few days. The nurse notes a heart rate of 110 beats/min and a blood pressure of 86/58 mm Hg. Which action by the nurse is the priority?
a. Give the client a bottle of water immediately.
b. Start an intravenous line for fluids.
c. Teach the client to drink 2 to 3 liters of water daily.
d. Perform an electrocardiogram.
a. Give the client a bottle of water immediately.
This athlete is mildly dehydrated as evidenced by the higher heart rate and lower blood pressure. The nurse can start hydrating the client with a bottle of water first, followed by teaching the client to drink 2 to 3 liters of water each day. An intravenous line may be ordered later, after the clients degree of dehydration is assessed. An electrocardiogram is not necessary at this time.
A male client comes into the emergency department with a serum creatinine of 2.2 mg/dL and a blood urea nitrogen (BUN) of 24 mL/dL. What question should the nurse ask first when taking this clients history?
a. Have you been taking any aspirin, ibuprofen, or naproxen recently?
b. Do you have anyone in your family with renal failure?
c. Have you had a diet that is low in protein recently?
d. Has a relative had a kidney transplant lately?
a. Have you been taking any aspirin, ibuprofen, or naproxen recently?
There are some medications that are nephrotoxic, such as the nonsteroidal anti-inflammatory drugs ibuprofen, aspirin, and naproxen. This would be a good question to initially ask the client since both the serum creatinine and BUN are elevated, indicating some renal problems. A family history of renal failure and kidney transplantation would not be part of the questioning and could cause anxiety in the client. A diet high in protein could be a factor in an increased BUN.
A client is admitted with acute kidney injury (AKI) and a urine output of 2000 mL/day. What is the major concern of the nurse regarding this clients care?
a. Edema and pain
b. Electrolyte and fluid imbalance
c. Cardiac and respiratory status
d. Mental health status
b. Electrolyte and fluid imbalance
This client may have an inflammatory cause of AKI with proteins entering the glomerulus and holding the fluid in the filtrate, causing polyuria. Electrolyte loss and fluid balance is essential. Edema and pain are not usually a problem with fluid loss. There could be changes in the clients cardiac, respiratory, and mental health status if the electrolyte imbalance is not treated.
A client with acute kidney injury has a blood pressure of 76/55 mm Hg. The health care provider ordered 1000 mL of normal saline to be infused over 1 hour to maintain perfusion. The client is starting to develop shortness of breath. What is the nurses priority action?
a. Calculate the mean arterial pressure (MAP).
b. Ask for insertion of a pulmonary artery catheter.
c. Take the clients pulse.
d. Slow down the normal saline infusion.
d. Slow down the normal saline infusion.
The nurse should assess that the client could be developing fluid overload and respiratory distress and slow down the normal saline infusion. The calculation of the MAP also reflects perfusion. The insertion of a pulmonary artery catheter would evaluate the clients hemodynamic status, but this should not be the initial action by the nurse. Vital signs are also important after adjusting the intravenous infusion.
A client has a serum potassium level of 6.5 mmol/L, a serum creatinine level of 2 mg/dL, and a urine output of 350 mL/day. What is the best action by the nurse?
a. Place the client on a cardiac monitor immediately.
b. Teach the client to limit high-potassium foods.
c. Continue to monitor the clients intake and output.
d. Ask to have the laboratory redraw the blood specimen.
a. Place the client on a cardiac monitor immediately.
The priority action by the nurse should be to check the cardiac status with a monitor. High potassium levels can lead to dysrhythmias. The other choices are logical nursing interventions for acute kidney injury but not the best immediate action.
A client has just had a central line catheter placed that is specific for hemodialysis. What is the most appropriate action by the nurse?
a. Use the catheter for the next laboratory blood draw.
b. Monitor the central venous pressure through this line.
c. Access the line for the next intravenous medication.
d. Place a heparin or heparin/saline dwell after hemodialysis.
d. Place a heparin or heparin/saline dwell after hemodialysis.
The central line should have a heparin or heparin/saline dwell after hemodialysis treatment. The central line catheter used for dialysis should not be used for blood sampling, monitoring central venous pressures, or giving drugs or fluids.
A client in the intensive care unit is started on continuous venovenous hemofiltration (CVVH). Which finding is the cause of immediate action by the nurse?
a. Blood pressure of 76/58 mm Hg
b. Sodium level of 138 mEq/L
c. Potassium level of 5.5 mEq/L
d. Pulse rate of 90 beats/min
a. Blood pressure of 76/58 mm Hg
Hypotension can be a problem with CVVH if replacement fluid does not provide enough volume to maintain blood pressure. The specially trained nurse needs to monitor for ongoing fluid and electrolyte replacement. The sodium level is normal and the potassium level is slightly elevated, which could be normal findings for someone with acute kidney injury. A pulse rate of 90 beats/min is normal.
The nurse is caring for four clients with chronic kidney disease. Which client should the nurse assess first upon initial rounding?
a. Woman with a blood pressure of 158/90 mm Hg
b. Client with Kussmaul respirations
c. Man with skin itching from head to toe
d. Client with halitosis and stomatitis
b. Client with Kussmaul respirations
Kussmaul respirations indicate a worsening of chronic kidney disease (CKD). The client is increasing the rate and depth of breathing to excrete carbon dioxide through the lungs. Hypertension is common in most clients with CKD, and skin itching increases with calcium-phosphate imbalances, another common finding in CKD. Uremia from CKD causes ammonia to be formed, resulting in the common findings of halitosis and stomatitis.
The charge nurse of the medical-surgical unit is making staff assignments. Which staff member should be assigned to a client with chronic kidney disease who is exhibiting a low-grade fever and a pericardial friction rub?
a. Registered nurse who just floated from the surgical unit
b. Registered nurse who just floated from the dialysis unit
c. Registered nurse who was assigned the same client yesterday
d. Licensed practical nurse with 5 years experience on this floor
c. Registered nurse who was assigned the same client yesterday
The client is exhibiting symptoms of pericarditis, which can occur with chronic kidney disease. Continuity of care is important to assess subtle differences in clients. Therefore, the registered nurse (RN) who was assigned to this client previously should again give care to this client. The float nurses would not be as knowledgeable about the unit and its clients. The licensed practical nurse may not have the education level of the RN to assess for pericarditis.
A male client with chronic kidney disease (CKD) is refusing to take his medication and has missed two hemodialysis appointments. What is the best initial action for the nurse?
a. Discuss what the treatment regimen means to him.
b. Refer the client to a mental health nurse practitioner.
c. Reschedule the appointments to another date and time. d. Discuss the option of peritoneal dialysis.
a. Discuss what the treatment regimen means to him.
The initial action for the nurse is to assess anxiety, coping styles, and the clients acceptance of the required treatment for CKD. The client may be in denial of the diagnosis. While rescheduling hemodialysis appointments may help, and referral to a mental health practitioner and the possibility of peritoneal dialysis are all viable options, assessment of the clients acceptance of the treatment should come first.
A client is taking furosemide (Lasix) 40 mg/day for management of chronic kidney disease (CKD). To detect the positive effect of the medication, what action of the nurse is best?
a. Obtain daily weights of the client.
b. Auscultate heart and breath sounds.
c. Palpate the clients abdomen.
d. Assess the clients diet history.
a. Obtain daily weights of the client.
Furosemide (Lasix) is a loop diuretic that helps reduce fluid overload and hypertension in clients with early stages of CKD. One kilogram of weight equals about 1 liter of fluid retained in the client, so daily weights are necessary to monitor the response of the client to the medication. Heart and breath sounds should be assessed if there is fluid retention, as in heart failure. Palpation of the clients abdomen is not necessary, but the nurse should check for edema. The diet history of the client would be helpful to assess electrolyte replacement since potassium is lost with this diuretic, but this does not assess the effect of the medication.
A client is diagnosed with chronic kidney disease (CKD). What is an ideal goal of treatment set by the nurse in the care plan to reduce the risk of pulmonary edema?
a. Maintaining oxygen saturation of 89%
b. Minimal crackles and wheezes in lung sounds
c. Maintaining a balanced intake and output
d. Limited shortness of breath upon exertion
c. Maintaining a balanced intake and output
With an optimal fluid balance, the client will be more able to eject blood from the left ventricle without increased pressure in the left ventricle and pulmonary vessels. Other ideal goals are oxygen saturations greater than 92%, no auscultated crackles or wheezes, and no demonstrated shortness of breath.
A client has a long history of hypertension. Which category of medications would the nurse expect to be ordered to avoid chronic kidney disease (CKD)?
a. Antibiotic
b. Histamine blocker
c. Bronchodilator
d. Angiotensin-converting enzyme (ACE) inhibitor
d. Angiotensin-converting enzyme (ACE) inhibitor
ACE inhibitors stop the conversion of angiotensin I to the vasoconstrictor angiotensin II. This category of medication also blocks bradykinin and prostaglandin, increases renin, and decreases aldosterone, which promotes vasodilation and perfusion to the kidney. Antibiotics fight infection, histamine blockers decrease inflammation, and bronchodilators increase the size of the bronchi; none of these medications helps slow the progression of CKD in clients with hypertension.
A 70-kg adult with chronic renal failure is on a 40-g protein diet. The client has a reduced glomerular filtration rate and is not undergoing dialysis. Which result would give the nurse the most concern?
a. Albumin level of 2.5 g/dL
b. Phosphorus level of 5 mg/dL
c. Sodium level of 135 mmol/L
d. Potassium level of 5.5 mmol/L
a. Albumin level of 2.5 g/dL
Protein restriction is necessary with chronic renal failure due to the buildup of waste products from protein breakdown. The nurse would be concerned with the low albumin level since this indicates that the protein in the diet is not enough for the clients metabolic needs. The electrolyte values are not related to the protein- restricted diet.
