1. A client is scheduled for a colonoscopy. Which instruction should the nurse provide?

Correct answer: B

Rationale: The correct instruction for a client scheduled for a colonoscopy is to drink a bowel preparation solution before the procedure. This solution helps cleanse the colon, ensuring clear visualization during the colonoscopy procedure. Choice A is incorrect because a light breakfast is usually recommended the day before the procedure, not on the day of the colonoscopy. Choice C is incorrect as it is important to stay hydrated and follow specific instructions regarding liquid intake. Choice D is incorrect as blood thinners may need to be adjusted or stopped before the colonoscopy to reduce the risk of bleeding during the procedure.

2. A patient with chronic obstructive pulmonary disease (COPD) is prescribed tiotropium. What is the primary purpose of this medication?

Correct answer: B

Rationale: Tiotropium is a long-acting bronchodilator used to relieve bronchospasm and improve airflow in patients with chronic obstructive pulmonary disease (COPD). It works by relaxing the muscles around the airways, leading to bronchodilation and improved breathing, making it an essential treatment in managing COPD symptoms.

3. A client with a history of chronic heart failure is experiencing severe shortness of breath and has pink, frothy sputum. Which action should the nurse take first?

Correct answer: B

Rationale: In a client with chronic heart failure experiencing severe shortness of breath and pink, frothy sputum, the priority action for the nurse is to place the client in a high Fowler's position. This position helps improve lung expansion, ease breathing, and enhance oxygenation by reducing venous return and decreasing preload on the heart. It is crucial to address the client's respiratory distress promptly before considering other interventions. Administering morphine sulfate (choice A) may be appropriate later to relieve anxiety and reduce the work of breathing, but positioning is the priority. Continuous ECG monitoring (choice C) and preparing for intubation (choice D) are important but secondary to addressing the respiratory distress and optimizing oxygenation.

4. The patient described in the preceding questions 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?

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. A positive serum IgG may persist indefinitely and cannot alone determine the failure of eradication. However, a decrease in quantitative IgG levels has been used to confirm treatment success. The urease breath test is recommended to assess the failure of eradication as it can detect the presence of H. pylori in the stomach, indicating treatment failure if positive.

5. A healthcare professional is preparing to administer digoxin 0.25 mg PO daily. The amount available is digoxin 0.125 mg tablets. How many tablets should the healthcare professional administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Correct answer: B

Rationale: To achieve the prescribed dose of 0.25 mg, the healthcare professional should administer 2 tablets of 0.125 mg each, totaling 0.25 mg.
