Nursing Elites

1. A client receiving warfarin (Coumadin) therapy should have which of the following laboratory results reviewed to evaluate the effectiveness of the therapy?

• A. Complete blood count (CBC).
• B. Prothrombin time (PT).
• C. International normalized ratio (INR).
• D. Partial thromboplastin time (PTT).

Correct answer: C

Rationale: The correct answer is C: International normalized ratio (INR). The INR is the most appropriate laboratory result to review when evaluating the effectiveness of warfarin (Coumadin) therapy. Warfarin is an anticoagulant medication, and the INR helps determine if the dosage is within a therapeutic range to prevent clotting or bleeding complications. Choice A, a Complete Blood Count (CBC), provides information about the cellular components of blood but does not directly assess the anticoagulant effects of warfarin. Choice B, Prothrombin time (PT), measures the time it takes for blood to clot but is not as specific for monitoring warfarin therapy as the INR. Choice D, Partial Thromboplastin Time (PTT), evaluates the intrinsic pathway of coagulation and is not the primary test used to monitor warfarin therapy.

2. A nurse plans care for clients with urinary incontinence. Which client is correctly paired with the appropriate intervention?

• A. A 29-year-old client after a difficult vaginal delivery – Habit training
• B. A 58-year-old postmenopausal client who is not taking estrogen therapy – Electrical stimulation
• C. A 64-year-old female with Alzheimer’s-type senile dementia – Bladder training
• D. A 77-year-old female who has difficulty ambulating – Exercise therapy

Correct answer: B

Rationale: The correct pairing is a 58-year-old postmenopausal client who is not taking estrogen therapy with electrical stimulation. Electrical stimulation is used for clients with stress incontinence related to menopause and low estrogen levels. Exercise therapy improves pelvic wall strength and is not specifically for ambulation issues. Habit training is more effective for cognitively impaired clients, like those with Alzheimer's-type senile dementia. Bladder training requires the client to be alert, aware, and able to resist the urge to urinate, which may not be suitable for clients with cognitive impairments.

3. A client in the intensive care unit is started on continuous venovenous hemofiltration (CVVH). Which finding should prompt immediate action by the nurse?

• A. Blood pressure of 76/58 mm Hg
• B. Sodium level of 138 mEq/L
• C. Potassium level of 5.5 mEq/L
• D. Pulse rate of 90 beats/min

Correct answer: A

Rationale: The correct answer is A: Blood pressure of 76/58 mm Hg. In a client undergoing continuous venovenous hemofiltration (CVVH), hypotension can be a significant concern if replacement fluid does not adequately maintain blood pressure. The nurse should take immediate action to address hypotension to prevent further complications. The sodium level of 138 mEq/L is within normal range, and a potassium level of 5.5 mEq/L, while slightly elevated, may be expected in a patient with acute kidney injury. A pulse rate of 90 beats/min falls within the normal range and does not typically require immediate intervention in this context.

4. A client with a history of peptic ulcer disease (PUD) is admitted after vomiting bright red blood several times over the course of 2 hours. In reviewing the laboratory results, the nurse finds the client's hemoglobin is 12 g/dL (120g/L) and the hematocrit is 35% (0.35). Which action should the nurse prepare to take?

• A. Continue monitoring for blood loss
• B. Administer 1,000 mL (1L) of normal saline
• C. Transfuse 2 units of platelets
• D. Prepare the client for emergency surgery

Correct answer: D

Rationale: The correct answer is to prepare the client for emergency surgery. The client's presentation with bright red blood in vomitus suggests active bleeding, which is a medical emergency. With a hemoglobin of 12 g/dL and a hematocrit of 35%, the client is likely experiencing significant blood loss that may require surgical intervention to address the source of bleeding. Continuing to monitor for blood loss (Choice A) is not appropriate in this acute situation where immediate action is necessary. Administering normal saline (Choice B) may help with fluid resuscitation but does not address the underlying cause of bleeding. Transfusing platelets (Choice C) is not indicated in this scenario as platelets are involved in clot formation and are not the primary treatment for active bleeding in this context.

5. The healthcare provider provides dietary instructions about iron-rich food to a client with iron deficiency anemia. Which food selection made by the client indicates a need for additional instructions?

• A. Liver
• B. Kidney beans
• C. Oranges
• D. Leafy green vegetables

Correct answer: C

Rationale: Oranges are not a good source of iron, so selecting oranges indicates a need for additional instructions. Oranges are high in vitamin C, which can enhance iron absorption from other sources, but they are not rich in iron themselves. Liver, kidney beans, and leafy green vegetables are good sources of iron and would be beneficial for a client with iron deficiency anemia. Therefore, the correct answer is C.
