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. The nurse is assessing a client with chronic kidney disease (CKD). Which finding is most important for the nurse to respond to first?

• A. Potassium 6.0 mEq/L.
• B. Daily urine output of 400 ml.
• C. Peripheral neuropathy.
• D. Uremic fetor.

Correct answer: A

Rationale: The correct answer is A. Potassium level of 6.0 mEq/L indicates hyperkalemia, which is a critical electrolyte imbalance in clients with chronic kidney disease. Hyperkalemia can lead to life-threatening arrhythmias, making it the priority finding to address. Choice B, a daily urine output of 400 ml, may indicate decreased kidney function but does not pose an immediate life-threatening risk compared to hyperkalemia. Peripheral neuropathy (Choice C) and uremic fetor (Choice D) are common manifestations of CKD but are not as urgent as addressing a potentially fatal electrolyte imbalance like hyperkalemia.

3. In a patient with diabetes, which of the following is a sign of hypoglycemia?

• A. Polydipsia
• B. Polyuria
• C. Dry skin
• D. Sweating

Correct answer: D

Rationale: Sweating is a common sign of hypoglycemia in patients with diabetes. When blood sugar levels drop too low, the body releases stress hormones like adrenaline, leading to symptoms such as sweating, shakiness, and palpitations. Polydipsia (excessive thirst) and polyuria (excessive urination) are more commonly associated with hyperglycemia (high blood sugar levels) in diabetes. Dry skin is not a typical symptom of hypoglycemia.

4. A middle-aged female client with diabetes mellitus is being treated for the third episode of acute pyelonephritis in the past year. The client asks, 'What can I do to help prevent these infections?' How should the nurse respond?

• A. Test your urine daily for the presence of ketone bodies and proteins.
• B. Use tampons rather than sanitary napkins during your menstrual period.
• C. Drink more water and empty your bladder more frequently during the day.
• D. Keep your hemoglobin A1c under 9% by controlling your blood sugar levels.

Correct answer: C

Rationale: The correct answer is C. Clients with long-standing diabetes mellitus are at risk for pyelonephritis due to various reasons. Elevated blood glucose levels in diabetes can lead to glucose spilling into the urine, altering the pH and creating a conducive environment for bacterial growth. Neuropathy associated with diabetes can reduce bladder tone and diminish the sensation of bladder fullness, resulting in less frequent voiding and increased risk of stasis and bacterial overgrowth. Increasing fluid intake, particularly water, and voiding regularly can help prevent stasis and microbial overgrowth. Testing urine for ketones and proteins or using tampons instead of sanitary napkins are not effective strategies for preventing pyelonephritis. Keeping the hemoglobin A1c levels below 9% is crucial for managing diabetes, but it alone does not directly prevent pyelonephritis.

5. What is the most common symptom of gastroesophageal reflux disease (GERD)?

• A. Heartburn.
• B. Nausea.
• C. Abdominal pain.
• D. Vomiting.

Correct answer: A

Rationale: The correct answer is A: Heartburn. Heartburn is the most common symptom of GERD as it occurs due to the reflux of stomach acid into the esophagus. This leads to a burning sensation in the chest that can worsen after eating, lying down, or bending over. Choice B, Nausea, is not typically the most common symptom of GERD, although it can occur in some cases. Choice C, Abdominal pain, is not a primary symptom of GERD and is more commonly associated with other gastrointestinal conditions. Choice D, Vomiting, is also not the most common symptom of GERD, although it can occur in severe cases or as a result of complications.
