Nursing Elites

1. A patient with heart failure is prescribed digoxin. What is the most important instruction the nurse should provide?

• A. Take an extra dose if you miss one.
• B. Avoid high-potassium foods.
• C. Report any visual disturbances.
• D. Stop taking the medication if your pulse is normal.

Correct answer: C

Rationale: The correct answer is C: 'Report any visual disturbances.' Patients taking digoxin should be instructed to report any visual disturbances, as this can be a sign of digoxin toxicity. Visual disturbances like changes in color vision, blurred vision, or seeing halos around lights can indicate an overdose of digoxin. Choices A, B, and D are incorrect. Instructing a patient to take an extra dose if they miss one can lead to overdose. Avoiding high-potassium foods is important for patients on potassium-sparing diuretics, not digoxin. Stopping the medication if the pulse is normal is incorrect, as the pulse rate alone is not an indicator of digoxin effectiveness or toxicity.

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

• A. Reduce mucus production
• B. Relieve bronchospasm
• C. Suppress cough
• D. Thin respiratory secretions

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. In a patient with chronic kidney disease (CKD) receiving erythropoietin therapy, what laboratory result should the nurse monitor to evaluate the effectiveness of this therapy?

• A. Serum creatinine
• B. White blood cell count
• C. Hemoglobin level
• D. Serum potassium

Correct answer: C

Rationale: The correct answer is C: Hemoglobin level. Erythropoietin therapy is used to stimulate red blood cell production in patients with chronic kidney disease who often develop anemia due to reduced erythropoietin production by the kidneys. Monitoring the hemoglobin level is essential to evaluate the effectiveness of erythropoietin therapy as an increase in hemoglobin indicates improved red blood cell production and better management of anemia in these patients. Serum creatinine, white blood cell count, and serum potassium levels are important parameters to monitor in CKD patients but are not specific indicators of the effectiveness of erythropoietin therapy for managing anemia.

4. A 62-year-old male client with a history of coronary artery disease complains that his heart is 'racing' and he often feels dizzy. His blood pressure is 110/60, and he uses portable oxygen at 2 liters per nasal cannula. Based on the rhythm shown, which prescription should the nurse administer?

• A. Give magnesium via secondary infusion.
• B. Initiate IV heparin solution as per protocol.
• C. Administer IV adenosine (Adenocard).
• D. Prepare for synchronized cardioversion.

Correct answer: C

Rationale: Administering IV adenosine is the appropriate intervention for a client with symptomatic tachycardia to restore normal sinus rhythm. Adenosine is a medication used to treat supraventricular tachycardia (SVT) by interrupting the reentry pathways through the AV node and restoring normal sinus rhythm. It is a rapid-acting medication given as a rapid IV push followed by a saline flush. The dose is typically administered in a healthcare setting where cardiac monitoring is available due to its potential to cause transient asystole.

5. A client with deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. Platelet count
• C. Activated partial thromboplastin time (aPTT)
• D. International normalized ratio (INR)

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the appropriate laboratory test to monitor the effectiveness of heparin therapy. Heparin works by prolonging the clotting time, which is reflected in the aPTT results. Monitoring aPTT helps ensure the patient is within the therapeutic range and not at risk of bleeding or clotting complications. Prothrombin time (PT) (Choice A) primarily measures the extrinsic pathway of coagulation and is used to monitor warfarin therapy, not heparin. Platelet count (Choice B) assesses the number of platelets present in the blood and is not specific to monitoring heparin therapy. International normalized ratio (INR) (Choice D) is used to monitor warfarin therapy, not heparin.
