Nursing Elites

1. The nurse is preparing to administer doses of hydrochlorothiazide (HydroDIURIL) and digoxin (Lanoxin) to a patient who has heart failure. The patient reports having blurred vision. The nurse notes a heart rate of 60 beats per minute and a blood pressure of 140/78 mm Hg. Which action will the nurse take?

• A. Administer the medications and request an order for serum electrolytes.
• B. Give both medications and evaluate serum blood glucose frequently.
• C. Hold the digoxin and notify the provider.
• D. Hold the hydrochlorothiazide and notify the provider.

Correct answer: C

Rationale: In this scenario, the patient is experiencing symptoms of digoxin toxicity, such as blurred vision and bradycardia. When thiazide diuretics like hydrochlorothiazide are taken with digoxin, the patient is at risk of digoxin toxicity due to the potential for thiazides to cause hypokalemia. Therefore, the correct action for the nurse to take is to hold the digoxin and notify the provider. Administering the medications without addressing the potential toxicity could worsen the patient's condition. Requesting serum electrolytes (Choice A) may be necessary but holding the digoxin takes priority. Evaluating serum blood glucose (Choice B) is not relevant to the current situation. Holding hydrochlorothiazide (Choice D) is not the best option as the primary concern is the digoxin toxicity that needs to be addressed promptly.

2. A nurse administers scopolamine as prescribed to a client in preparation for surgery. For which side effect of this medication does the nurse monitor the client?

• A. Pupil constriction
• B. Increased urine output
• C. Complaints of dry mouth
• D. Complaints of feeling sweaty

Correct answer: D

Rationale: The correct answer is D: 'Complaints of feeling sweaty.' Scopolamine, an anticholinergic medication, commonly causes the side effect of decreased sweating, not increased urine output or pupil constriction. While dry mouth is a possible side effect, it is less likely than the altered sweating pattern. Therefore, the nurse should monitor the client for complaints of feeling sweaty due to the potential side effect of decreased sweating associated with scopolamine.

3. A client in the emergency department is severely dehydrated and is prescribed 3 L of intravenous fluid over 6 hours. At what rate (mL/hr) should the nurse set the intravenous pump to infuse the fluids? (Record your answer using a whole number.)

• A. 500 mL/hr
• B. 400 mL/hr
• C. 550 mL/hr
• D. 600 mL/hr

Correct answer: A

Rationale: To calculate the rate of the intravenous pump, divide the total volume of fluid (3 L = 3000 mL) by the total time in hours (6 hours), which equals 500 mL/hr. The correct answer is A. Choice B (400 mL/hr) is incorrect as it would result in a slower infusion rate. Choice C (550 mL/hr) and Choice D (600 mL/hr) are incorrect as they would result in a faster infusion rate, exceeding the prescribed amount of fluid to be infused over 6 hours.

4. Laboratory findings indicate that a client's serum potassium level is 2.5 mEq/L. What action should the nurse take?

• A. Inform the healthcare provider of the need for potassium replacement.
• B. Prepare to administer a glucose-insulin-potassium replacement.
• C. Change the plan of care to include hourly urinary output measurement.
• D. Instruct the client to increase daily intake of potassium-rich foods.

Correct answer: A

Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. The immediate action the nurse should take is to inform the healthcare provider of the need for potassium replacement. Option B, preparing to administer glucose-insulin-potassium replacement, is not the first-line intervention; it may be considered in specific situations but requires a healthcare provider's prescription. Option C, changing the plan of care to include hourly urinary output measurement, is not the priority when managing critically low potassium levels. Option D, instructing the client to increase daily intake of potassium-rich foods, is not appropriate in this acute situation where immediate intervention is needed to address the dangerously low potassium level.

5. If a client displays risk factors for coronary artery disease, such as smoking cigarettes, eating a diet high in saturated fat, or leading a sedentary lifestyle, techniques of behavior modification may be used to help the client change the behavior. The nurse can best reinforce new adaptive behaviors by:

• A. Explaining how the risk factor behaviors lead to poor health.
• B. Withholding praise until the new behavior is well established.
• C. Rewarding the client whenever the acceptable behavior is performed.
• D. Instilling mild fear in the client to extinguish the behavior.

Correct answer: C

Rationale: The correct answer is C. A fundamental principle of behavior modification is that behavior that is rewarded is more likely to be continued. Therefore, rewarding the client whenever the acceptable behavior is performed is the best approach to reinforce new adaptive behaviors. Choice A is incorrect because simply explaining how the risk factor behaviors lead to poor health may not be as effective in promoting behavior change compared to positive reinforcement. Choice B is incorrect because withholding praise can hinder progress and motivation for the client. Choice D is incorrect because instilling fear is not a recommended method in behavior modification. It can lead to negative psychological effects and is not a sustainable approach to behavior change.
