Nursing Elites

1. When caring for a client receiving warfarin sodium (Coumadin), which lab test would the nurse monitor to determine therapeutic response to the drug?

• A. Bleeding time
• B. Coagulation time
• C. Prothrombin time
• D. Partial thromboplastin time

Correct answer: C

Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.

2. A client with a history of seizures is prescribed phenytoin (Dilantin). What side effect should the healthcare provider report immediately?

• A. Increased appetite
• B. Dry mouth
• C. Nausea and vomiting
• D. Gingival hyperplasia

Correct answer: D

Rationale: Gingival hyperplasia is a significant side effect associated with phenytoin therapy. It is characterized by an overgrowth of gum tissue, which can lead to issues such as difficulty in speaking, eating, and maintaining proper oral hygiene. This condition can progress rapidly and may require immediate intervention by the healthcare provider to prevent further complications. Increased appetite, dry mouth, and nausea/vomiting are common side effects of various medications, but they are not as urgent or serious as gingival hyperplasia in a client taking phenytoin.

3. A client with heart failure and a new prescription for hydrochlorothiazide is receiving discharge teaching about safety considerations from a nurse. Which statement by the client indicates an understanding of the teaching?

• A. “I will take a hot bath before going to bed.”
• B. “I will take my new medication in the evening.”
• C. “I will leave a light on in my bathroom at night.”
• D. “I will weigh myself once weekly.”

Correct answer: C

Rationale: The correct answer is C. Leaving a light on in the bathroom at night is important for an older adult with heart failure who is taking hydrochlorothiazide, a diuretic that can cause nocturia. This safety measure helps prevent falls during nighttime bathroom visits. Option A is incorrect because taking a hot bath before bed can increase the risk of falls due to potential dizziness. Option B does not directly relate to safety considerations but rather the timing of medication administration. Option D, weighing oneself once weekly, is important for monitoring fluid retention but does not address safety concerns related to nocturia and falls.

4. The LPN/LVN mixes 50 mg of Nipride in 250 ml of D5W and plans to administer the solution at a rate of 5 mcg/kg/min to a client weighing 182 pounds. Using a drip factor of 60 gtt/ml, how many drops per minute should the client receive?

• A. 31 gtt/min.
• B. 62 gtt/min.
• C. 93 gtt/min.
• D. 124 gtt/min.

Correct answer: D

Rationale: To calculate the drops per minute for the client, first, convert the weight from pounds to kilograms by dividing 182 by 2.2, which equals 82.72 kg. Then, calculate the dose in mcg/min by multiplying the weight in kg by the rate (82.72 kg * 5 mcg/kg/min = 413.6 mcg/min). Next, convert 50 mg to mcg (50 mg * 1000 = 50,000 mcg). Divide the total mcg (50,000 mcg) by the dose per minute (413.6 mcg/min) to get approximately 121 gtt/min. However, since the drip factor is 60 gtt/ml, the correct answer is 124 gtt/min, ensuring the accurate administration rate of the medication. Therefore, choice 'D' is the correct answer. Choices 'A', 'B', and 'C' are incorrect as they do not accurately reflect the calculated drops per minute based on the given information.

5. A client with chronic kidney disease is being assessed. Which laboratory value would be most concerning?

• A. Serum creatinine of 3.0 mg/dL
• B. Blood urea nitrogen (BUN) of 45 mg/dL
• C. Serum potassium of 6.5 mEq/L
• D. Hemoglobin of 10 g/dL

Correct answer: C

Rationale: In a client with chronic kidney disease, an elevated serum potassium level (hyperkalemia) is the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias due to its effect on the electrical conduction system of the heart. Monitoring and managing serum potassium levels are crucial in patients with chronic kidney disease to prevent serious complications. While elevated serum creatinine (Choice A) and Blood Urea Nitrogen (BUN) levels (Choice B) indicate impaired kidney function, hyperkalemia poses an immediate risk of cardiac complications. Hemoglobin levels (Choice D) are typically lower in chronic kidney disease due to decreased erythropoietin production, but they do not present an immediate life-threatening risk like hyperkalemia.
