PN 140 Final Exam NCLEX Practice Questions And Correct Answers.

A nurse is caring for a client with systemic lupus erythematosus (SLE). The client begins to cry and tells the nurse that she is afraid that her skin will be disfigured with lesions. Which intervention does the nurse plan to teach this client to minimize skin infections associated with SLE? Select all that apply. A) Use sunscreen with an SPF of 15 or greater. B) Remain indoors on sunny days. C) Avoid swimming in a pool or the ocean. D) Avoid sun exposure between 10:00 a.m. and 3:00 p.m. E) Decrease sun exposure between 3:00 p.m. and 5:00 p.m. - correct answer Answer: A, D The nurse teaches the client to live a normal life with a few extra precautions. There is a relationship between sun exposure and infection, so the client is taught to use sunscreen with an SPF of at least 15 and to avoid the sun between 10:00 a.m. and 3:00 p.m. The client may swim but should reapply sunscreen after swimming. The client does not need to stay indoors on sunny days or to decrease sun exposure between 3:00 p.m. and 5:00 p.m. A patient on a medical unit has a potassium level of 6.8 mEq/L. What is the priority action that the nurse should take? a. Place the patient on a cardiac monitor. b. Check the patient's BP. c. Instruct the patient to avoid high-potassium foods. d. Call the lab and request a redraw of the lab to verify results. - correct answer a. Dysrhythmias may occur with an elevated potassium level and are potentially lethal. Monitor the rhythm while contacting physician or calling the rapid response team. A patient is admitted to the hospital with CKD. You understand that this condition is characterized by A. Progressive irreversible destruction of the kidneys B. A rapid decrease in urinary output with an elevated BUN level C. Increasing creatinine clearance with a decrease in urinary output D. Prostration, somnolence, and confusion with coma and imminent death - correct answer A. Progressive irreversible destruction of the kidneys CKD involves progressive, irreversible loss of kidney function. Measures indicated in the conservative therapy of CKD include A. decreased fluid intake, carbohydrate intake, and protein intake. B. increased fluid intake; decreased carbohydrate intake and protein intake. C. decreased fluid intake and protein intake; increased carbohydrate intake. D. decreased fluid intake and carbohydrate intake; increased protein intake. - correct answer C. decreased fluid intake and protein intake; increased carbohydrate intake. Water and any other fluids are not routinely restricted in the pre-end-stage renal disease (ESRD) stages. Patients on hemodialysis have a more restricted diet than patients receiving peritoneal dialysis. For those receiving hemodialysis, as their urinary output diminishes, fluid restrictions are enhanced. Intake depends on the daily urine output. Generally, 600 mL (from insensible loss) plus an amount equal to the previous day's urine output is allowed for a patient receiving hemodialysis. Patients are advised to limit fluid intake so that weight gains are no more than 1 to 3 kg between dialyses (interdialytic weight gain). For the patient who is undergoing dialysis, protein is not routinely restricted. The beneficial role of protein restriction in CKD stages 1 through 4 as a means to reduce the decline in kidney function is being studied. Historically, dietary counseling often encouraged restriction of protein for CKD patients. Although there is some evidence that protein restriction has benefits, many patients find these diets difficult to adhere to. For CKD stages 1 through 4, many clinicians encourage a diet with normal protein intake. However, you should teach patients to avoid high-protein diets and supplements because they may overstress the diseased kidneys. Nurses need to educate patients at risk for CKD. Which individuals are considered to be at increased risk (select all that apply)? A. Older African Americans B. Individuals older than 60 years C. Those with a history of pancreatitis D. Those with a history of hypertension E. Those with a history of type 2 diabetes - correct answer A. Older African Americans B. Individuals older than 60 years D. Those with a history of hypertension E. Those with a history of type 2 diabetes Risk factors for CKD include diabetes mellitus, hypertension, age older than 60 years, cardiovascular disease, family history of CKD, exposure to nephrotoxic drugs, and ethnic minorities (e.g., African American, Native American). Which statement regarding continuous ambulatory peritoneal dialysis (CAPD) is of highest priority when teaching a patient new to this procedure? A. "It is essential that you maintain aseptic technique to prevent peritonitis." B. "You will be allowed a more liberal protein diet after you complete CAPD." C. "It is important for you to maintain a daily written record of blood pressure and weight." D. "You must continue regular medical and nursing follow-up visits while performing CAPD." - correct answer A. "It is essential that you maintain aseptic technique to prevent peritonitis." Peritonitis is a potentially fatal complication of peritoneal dialysis, and it is imperative to teach the patient methods to prevent it from occurring. Although the other teaching statements are accurate, they do not address the potential for mortality by peritonitis, making that nursing action the highest priority. How should you assess the patency of a newly placed arteriovenous graft for dialysis? A. Irrigate the graft daily with low-dose heparin. B. Monitor for any increase in blood pressure in the affected arm. C. Listen with a stethoscope over the graft for presence of a bruit. D. Frequently monitor the pulses and neurovascular status distal to the graft. - correct answer C. Listen with a stethoscope over the graft for presence of a bruit. A thrill can be felt by palpating the area of anastomosis of the arteriovenous graft, and a bruit can be heard with a stethoscope. The bruit and thrill are created by arterial blood rushing into the vein. What are the main advantages of peritoneal dialysis compared to hemodialysis? A. No medications are required because of the enhanced efficiency of the peritoneal membrane in removing toxins. B. The diet is less restricted and dialysis can be performed at home. C. The dialysate is biocompatible and causes no long-term consequences. D. High glucose concentrations of the dialysate cause a reduction in appetite, promoting weight loss. - correct answer B. The diet is less restricted and dialysis can be performed at home. Advantages of peritoneal dialysis include fewer dietary restrictions and home dialysis is possible. The nurse teaches a client who is recovering from acute kidney disease to avoid which type of medication? A Nonsteroidal anti-inflammatory drugs (NSAIDs) B Angiotensin-converting enzyme (ACE) inhibitors C Opiates D Calcium channel blockers filtration rate and blood flow within the kidney. - correct answer A Nonsteroidal anti-inflammatory drugs (NSAIDs) NSAIDs may be nephrotoxic to a client with acute kidney disease, and should be avoided. ACE inhibitors are used for treatment of hypertension and to protect the kidneys, especially in the diabetic client, from progression of kidney disease. Opiates may be used by clients with kidney disease if severe pain is present; however, excretion may be delayed. Calcium channel blockers can improve the glomerular A client with end-stage kidney disease has been put on fluid restrictions. Which assessment finding indicates that the client has not adhered to this restriction? A Blood pressure of 118/78 mm Hg B Weight loss of 3 pounds during hospitalization C Dyspnea and anxiety at rest D Central venous pressure (CVP) of 6 mm Hg - correct answer C Dyspnea and anxiety at rest Dyspnea is a sign of fluid overload and possible pulmonary edema; the nurse should assist the client in correlating symptoms of fluid overload with nonadherence to fluid restriction. Nonadherence to fluid restriction results in fluid volume excess and higher blood pressures; 118/78 mm Hg is a normal blood pressure. Excess fluid intake and fluid retention are manifested by an elevated CVP (8 mm Hg) and weight gain, not weight loss. Which assessment finding represents a positive response to erythropoietin (Epogen, Procrit) therapy? A Hematocrit of 26.7% B Potassium within normal range C Absence of spontaneous fractures D Less fatigue - correct answer D Less fatigue Treatment of anemia with erythropoietin will result in increased hemoglobin and hematocrit (H&H) and decreased shortness of breath and fatigue. A hematocrit value of 26.7% is low; erythropoietin should restore the hematocrit to at least 36% to be effective. Erythropoietin causes more red blood cells to be produced, increasing H&H, not potassium. Calcium supplements and phosphate binders prevent renal osteodystrophy; erythropoietin treats anemia. When caring for a client who receives peritoneal dialysis (PD), which finding does the nurse report to the provider immediately? A Pulse oximetry reading of 95% B Sinus bradycardia, rate of 58 beats/min C Blood pressure of 148/90 mm Hg
