Nursing Elites

1. A client with heart failure is receiving digoxin (Lanoxin). Which finding indicates that the medication is effective?

• A. Increased heart rate.
• B. Decreased pedal edema.
• C. Elevated blood pressure.
• D. Improved urine output.

Correct answer: B

Rationale: In a client with heart failure, decreased pedal edema is a positive indicator of improved cardiac output and reduced fluid retention. Digoxin works by increasing the strength of the heart's contractions, leading to improved circulation and reduced symptoms of heart failure, such as edema. Monitoring for decreased pedal edema is essential to assess the effectiveness of digoxin therapy. Choices A, C, and D are incorrect because an increased heart rate, elevated blood pressure, and improved urine output are not specific indicators of digoxin's effectiveness in managing heart failure. Instead, the focus should be on improvements related to fluid retention and cardiac function, like decreased pedal edema.

2. A primipara at 38-weeks gestation is admitted to labor and delivery for a biophysical profile (BPP). The nurse should prepare the client for what procedures?

• A. Chorionic villus sampling under ultrasound.
• B. Amniocentesis and fetal monitoring.
• C. Ultrasonography and nonstress test.
• D. Oxytocin challenge test and fetal heart rate monitoring.

Correct answer: C

Rationale: A biophysical profile (BPP) is a prenatal test that assesses the well-being of the fetus. It typically includes ultrasonography to evaluate fetal movements, muscle tone, breathing movements, and amniotic fluid volume. Additionally, a nonstress test is performed to monitor the fetal heart rate in response to its movements. These tests help in determining the overall health and viability of the fetus, making them essential components of prenatal care for assessing fetal well-being.

3. 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.

4. A 28-year-old woman presents with abdominal pain, diarrhea, and rectal bleeding. She has a history of similar episodes in the past. What is the most likely diagnosis?

• A. Ulcerative colitis
• B. Irritable bowel syndrome
• C. Celiac disease
• D. Diverticulitis

Correct answer: A

Rationale: The constellation of symptoms including abdominal pain, diarrhea, and rectal bleeding in a young woman with a history of similar episodes is highly suggestive of ulcerative colitis. This chronic inflammatory condition primarily affects the colon and rectum, leading to symptoms such as bloody diarrhea, abdominal pain, and urgency. The recurrent nature of her symptoms and the presence of rectal bleeding further support this diagnosis over other conditions listed, such as irritable bowel syndrome, celiac disease, or diverticulitis, which typically do not present with the same combination of symptoms and history.

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

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. Bleeding time
• D. Platelet count

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding. Prothrombin time (PT) primarily assesses the extrinsic pathway and is not as sensitive to heparin therapy. Bleeding time and platelet count are not specific tests for monitoring the effectiveness of heparin therapy in DVT.
