Nursing Elites

1. A client with chronic kidney disease (CKD) is scheduled for hemodialysis. Which pre-dialysis assessment finding should the nurse report to the healthcare provider?

• A. Serum potassium of 5.5 mEq/L.
• B. Blood pressure of 180/90 mm Hg.
• C. Heart rate of 80 beats per minute.
• D. Serum sodium of 140 mEq/L.

Correct answer: B

Rationale: The correct answer is B. A blood pressure of 180/90 mm Hg is elevated and should be reported to the healthcare provider before hemodialysis. Hypertension can have a significant impact on the effectiveness and safety of the dialysis treatment. Controlling blood pressure before the procedure is crucial to prevent complications during the dialysis session.

2. When assessing a male client who is receiving a unit of packed red blood cells (PRBCs), the nurse notes that the infusion was started 30 minutes ago, and 50 ml of blood is left to be infused. The client's vital signs are within normal limits. He reports feeling 'out of breath' but denies any other complaints. What action should the nurse take at this time?

• A. Administer a PRN prescription for diphenhydramine (Benadryl).
• B. Start the normal saline attached to the Y-tubing at the same rate.
• C. Decrease the intravenous flow rate of the PRBC transfusion.
• D. Ask the respiratory therapist to administer PRN albuterol (Ventolin).

Correct answer: C

Rationale: In this scenario, the client is experiencing symptoms of shortness of breath, which could indicate fluid overload from the PRBC transfusion. By decreasing the intravenous flow rate of the transfusion, the nurse can slow down the rate of blood being infused, potentially alleviating the symptoms of fluid overload and shortness of breath. This intervention can help prevent further complications and promote the client's comfort and safety.

3. Which of the following statements about Helicobacter pylori (H. pylori) is false?

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

4. The patient described in the preceding question has a positive H. pylori antibody blood test. She is compliant with the medical regimen you prescribe. Although her symptoms initially respond, she returns to see you six months later with the same symptoms. Which of the following statements is correct?

• A. She is at low risk for reinfection with H. pylori
• B. A positive serum IgG indicates that eradication of H. pylori was successful
• C. The urease breath test is an ideal test to document failure of eradication
• D. Dyspepsia typically worsens with H. pylori eradication

Correct answer: C

Rationale: Reinfection with H. pylori is rare, and the persistence of infection usually indicates poor compliance with the medical regimen or antibiotic resistance. The serum IgG may remain positive indefinitely and cannot be used to determine failure of eradication; however, a decrease in quantitative IgG levels has been utilized to indicate treatment success. If available, either the stool antigen or urease breath test is ideal to document treatment failure due to their high sensitivity, specificity, and ease of performance. The relationship between dyspepsia and H. pylori is controversial, but generally, dyspepsia does not typically improve with H. pylori eradication.

5. A client with diabetes has a new prescription for 14 units of regular insulin and 28 units of NPH insulin subcutaneously at breakfast daily. What is the total number of units of insulin that should be prepared in the insulin syringe?

• A. 42 units
• B. 14 units
• C. 28 units
• D. 32 units

Correct answer: A

Rationale: To calculate the total number of units of insulin, you need to add the 14 units of regular insulin to the 28 units of NPH insulin, which equals 42 units. Therefore, the nurse should prepare 42 units of insulin in the syringe for the client.
