Nursing Elites

1. A client with acute kidney injury (AKI) weighing 50kg and having a potassium level of 6.7mEq/L (6.7mmol/L) is admitted to the hospital. Which prescribed medication should the nurse administer first?

• A. Calcium acetate, one tablet by mouth
• B. Sodium polystyrene sulfonate, 15 grams by mouth
• C. Epoetin Alfa, recombinant, 2,500 units subcutaneously
• D. Sevelamer, one tablet by mouth

Correct answer: B

Rationale: In a client with acute kidney injury (AKI) and hyperkalemia, the priority intervention is to lower the potassium level swiftly. Sodium polystyrene sulfonate is a medication used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, reducing the overall potassium levels. Calcium acetate, epoetin alfa, and sevelamer are not indicated for the immediate reduction of potassium levels in hyperkalemia. Calcium acetate is used to control phosphate levels, epoetin alfa is a medication to treat anemia by stimulating red blood cell production, and sevelamer is a phosphate binder used in chronic kidney disease to reduce phosphate levels.

2. Which of the following lipid abnormalities is a risk factor for the development of atherosclerosis and peripheral vascular disease?

• A. Low concentration of triglycerides.
• B. High levels of high-density lipoprotein (HDL) cholesterol.
• C. High levels of low-density lipoprotein (LDL) cholesterol.
• D. Low levels of LDL cholesterol.

Correct answer: C

Rationale: The correct answer is C: High levels of low-density lipoprotein (LDL) cholesterol. High levels of LDL cholesterol contribute to the development of atherosclerosis and peripheral vascular disease by being deposited in the blood vessel walls, leading to the formation of plaques that can obstruct blood flow. Choice A is incorrect as a low concentration of triglycerides is not typically associated with an increased risk of atherosclerosis or PVD. Choice B is incorrect as high levels of high-density lipoprotein (HDL) cholesterol are actually considered protective against atherosclerosis as it helps remove cholesterol from arteries. Choice D is incorrect as low levels of LDL cholesterol are not typically considered a risk factor for atherosclerosis or PVD.

3. The healthcare provider assesses a client with cirrhosis and finds 4+ pitting edema of the feet and legs, and massive ascites. Which mechanism contributes to edema and ascites in clients with cirrhosis?

• A. Hyperaldosteronism causing increased sodium transport ion in renal tubules
• B. Decreased portacaval pressure with greater collateral circulation
• C. Decreased renin-angiotensin response related to increased renal blood flow
• D. Hypoalbuminemia that results in decreased colloidal oncotic pressure

Correct answer: D

Rationale: In clients with cirrhosis, hypoalbuminemia leads to decreased colloidal oncotic pressure. This reduction in oncotic pressure contributes to the development of edema in the feet and legs (pitting edema) and ascites in the abdomen. Hyperaldosteronism (choice A) would lead to sodium retention but is not the primary mechanism behind edema and ascites in cirrhosis. Decreased portacaval pressure with greater collateral circulation (choice B) is not directly related to the pathophysiology of edema and ascites in cirrhosis. Decreased renin-angiotensin response related to increased renal blood flow (choice C) does not play a significant role in the development of edema and ascites in cirrhosis compared to the impact of hypoalbuminemia on colloidal oncotic pressure.

4. A client who just returned from the recovery room after a tonsillectomy and adenoidectomy is restless, and her pulse rate is increased. As the nurse continues the assessment, the client begins to vomit a copious amount of bright-red blood. The immediate nursing action is to:

• A. Notify the surgeon
• B. Continue the assessment
• C. Check the client’s blood pressure
• D. Obtain a flashlight, gauze, and a curved hemostat

Correct answer: A

Rationale: In the scenario described, the client's presentation with bright-red blood vomiting after a tonsillectomy and adenoidectomy is highly concerning for an immediate postoperative hemorrhage, which can be life-threatening. The priority action for the nurse is to notify the surgeon immediately. Prompt communication with the surgeon is vital to ensure swift intervention and appropriate management to address the hemorrhage effectively. Continuing the assessment, checking the client's blood pressure, or obtaining equipment are all secondary actions in this critical situation and would delay the necessary urgent intervention required to manage the hemorrhage effectively.

5. When a patient is receiving high doses of a cephalosporin, which laboratory values will this patient's nurse monitor closely?

• A. Blood urea nitrogen (BUN), serum creatinine, and liver function tests
• B. Complete blood count and electrolytes
• C. Serum calcium and magnesium
• D. Serum glucose and lipids

Correct answer: A

Rationale: When a patient is receiving high doses of a cephalosporin, such as cefazolin, the nurse should closely monitor laboratory values that indicate renal and hepatic function. This includes checking the Blood Urea Nitrogen (BUN) and serum creatinine levels to assess kidney function. Additionally, monitoring liver function tests, such as AST, ALT, ALP, LDH, and bilirubin, is essential as cephalosporins can affect liver enzymes. Therefore, options B, C, and D are incorrect as they do not specifically address the parameters that are most pertinent when administering high doses of cephalosporins.
