Nursing Elites

1. In a client with congestive heart failure, the nurse would be correct in withholding a dose of digoxin without specific instruction from the healthcare provider if the client's

• A. serum digoxin level is 1.5 ng/mL.
• B. blood pressure is 104/68 mmHg.
• C. serum potassium level is 3 mEq/L.
• D. apical pulse is 68/min.

Correct answer: C

Rationale: The correct answer is C. Hypokalemia can precipitate digitalis toxicity in individuals on digoxin, increasing the risk of dangerous dysrhythmias. A serum potassium level of 3 mEq/L is below the normal range (3.5 to 5.5 mEq/L) and indicates hypokalemia, which can potentiate the effects of digoxin. Choices A, B, and D are not directly related to the potential for digitalis toxicity. Serum digoxin level of 1.5 ng/mL is within the therapeutic range, blood pressure of 104/68 mmHg is not a contraindication for administering digoxin, and an apical pulse of 68/min is within the normal range and not a reason to withhold digoxin.

2. Which of the following conditions is most commonly associated with a high risk of stroke?

• A. Hypertension.
• B. Diabetes.
• C. Obesity.
• D. Smoking.

Correct answer: A

Rationale: Hypertension is the correct answer. Hypertension, also known as high blood pressure, is a major risk factor for stroke because it puts increased pressure on blood vessels in the brain, making them more prone to damage and increasing the likelihood of a stroke. While diabetes, obesity, and smoking are also risk factors for stroke, hypertension is the most commonly associated condition with a high risk of stroke due to its direct impact on the blood vessels.

3. A client is being prepared for a colonoscopy. Into which position does the nurse assist the client for the procedure?

• A. Left Sims' position
• B. Lithotomy position
• C. Knee-chest position
• D. Right Sims' position

Correct answer: A

Rationale: During a colonoscopy, the client is positioned in the left Sims' position. This position is chosen as it optimally utilizes the client’s anatomy to facilitate the introduction of the colonoscope. The lithotomy position (Choice B) is commonly used for gynecological exams, not colonoscopies. The knee-chest position (Choice C) is typically employed for rectal examinations or certain surgical procedures, not colonoscopies. The right Sims' position (Choice D) is a less common position for colonoscopy compared to the left Sims' position.

4. The client who has a history of Parkinson's disease for the past 5 years is being assessed by the nurse. What symptoms would this client most likely exhibit?

• A. Loss of short-term memory, facial tics, and grimaces, and constant writhing movements.
• B. Shuffling gait, masklike facial expression, and tremors of the head.
• C. Extreme muscular weakness, easy fatigability, and ptosis.
• D. Numbness of the extremities, loss of balance, and visual disturbances.

Correct answer: B

Rationale: Parkinson's Disease, a common neurologic progressive disorder in older clients, is characterized by symptoms such as shuffling gait, masklike facial expression, and tremors of the head and hands. Choice A is incorrect as symptoms like loss of short-term memory, facial tics, and constant writhing movements are not typically associated with Parkinson's disease. Choice C is incorrect as extreme muscular weakness, easy fatigability, and ptosis are more indicative of other conditions like myasthenia gravis. Choice D is incorrect as numbness of the extremities, loss of balance, and visual disturbances are not classic symptoms of Parkinson's disease.

5. After teaching a client with early polycystic kidney disease (PKD) about nutritional therapy, the nurse assesses the client’s understanding. Which statement made by the client indicates a correct understanding of the teaching?

• A. I will take a laxative every night before going to bed.
• B. I must increase my intake of dietary fiber and fluids.
• C. I shall only use salt when I am cooking my own food.
• D. I’ll eat white bread to minimize gastrointestinal gas.

Correct answer: B

Rationale: Choice B is the correct answer. Clients with PKD often experience constipation, which can be managed by increasing their intake of dietary fiber and fluids. This helps promote bowel regularity. Laxatives should be used cautiously and not as a routine solution. Choice A is incorrect as regular laxative use is not recommended. Choice C is incorrect as a low-salt diet is typically advised for clients with PKD, not just limiting salt while cooking. Choice D is incorrect as white bread is low in fiber and not beneficial for managing constipation, which is common in PKD.
