HESI RN Medical Surgical Practice Exam
1. The nurse is caring for a newly admitted patient who will receive digoxin to treat a cardiac dysrhythmia. The patient takes hydrochlorothiazide (HydroDIURIL) and reports regular use of over-the-counter laxatives. Before administering the first dose of digoxin, the nurse will review the patient’s electrolytes with careful attention to the levels of which electrolytes?
- A. Calcium and magnesium
- B. Sodium and calcium
- C. Potassium and chloride
- D. Potassium and magnesium
Correct answer: D
Rationale: Before administering digoxin, the nurse must review the patient's electrolyte levels, focusing on potassium and magnesium. Hypomagnesemia, similar to hypokalemia, can enhance the action of digitalis and lead to digitalis toxicity. Laxatives and diuretics, like hydrochlorothiazide, can deplete both potassium and magnesium. Therefore, monitoring these electrolytes is crucial to prevent potential adverse effects associated with digoxin therapy. Choice A (Calcium and magnesium) is incorrect because calcium levels are not specifically mentioned as crucial for digoxin therapy. Choice B (Sodium and calcium) is incorrect as sodium is not typically monitored in relation to digoxin therapy. Choice C (Potassium and chloride) is incorrect because although potassium is vital, chloride is not typically associated with digoxin therapy.
2. The patient is receiving sulfadiazine. The healthcare provider knows that this patient’s daily fluid intake should be at least which amount?
- A. 1000 mL/day
- B. 1200 mL/day
- C. 2000 mL/day
- D. 2400 mL/day
Correct answer: C
Rationale: Sulfadiazine may lead to crystalluria, a condition where crystals form in the urine. Adequate fluid intake helps prevent this adverse effect by ensuring urine is dilute enough to prevent crystal formation. The recommended daily fluid intake for a patient receiving sulfadiazine is at least 2000 mL/day. Choices A, B, and D are incorrect because they do not provide a sufficient amount of fluid intake to prevent crystalluria in patients on sulfadiazine.
3. The nurse is instructing the client on insulin administration. The client's morning dose of insulin is 10 units of regular and 22 units of NPH. The nurse checks the dose accuracy with the client. The nurse determines that the client has prepared the correct dose when the syringe reads how many units?
- A. 10 units.
- B. 22 units.
- C. 32 units.
- D. 24 units.
Correct answer: C
Rationale: The correct dose would be 32 units, which is the sum of 10 units of regular insulin and 22 units of NPH. It is essential to combine the doses of both types of insulin to ensure the client administers the correct total dose. Choices A and B represent the individual doses of regular and NPH insulin, respectively, not the combined total. Choice D is incorrect as it does not reflect the sum of both insulin doses.
4. After delegating care to an unlicensed assistive personnel (UAP) for a client who is prescribed habit training to manage incontinence, a nurse evaluates the UAP’s understanding. Which action indicates the UAP needs additional teaching?
- A. Toileting the client after breakfast
- B. Changing the client’s incontinence brief when wet
- C. Encouraging the client to drink fluids
- D. Recording the client’s incontinence episodes
Correct answer: B
Rationale: The correct action that indicates the UAP needs additional teaching is choice B, 'Changing the client’s incontinence brief when wet.' Habit training is a technique used to manage incontinence, and it is undermined by the use of absorbent incontinence briefs or pads. The nurse should re-educate the UAP on the technique of habit training, which involves scheduled toileting and promoting bladder control. Choices A, C, and D are appropriate actions that support the client’s care: toileting the client after meals, encouraging fluid intake, and documenting incontinence episodes are all important aspects of managing incontinence and monitoring the client's condition.
5. The nurse is caring for a patient who develops marked edema and a low urine output as a result of heart failure. Which medication will the nurse expect the provider to order for this patient?
- A. Digoxin (Lanoxin)
- B. Furosemide (Lasix)
- C. Hydrochlorothiazide (HydroDIURIL)
- D. Spironolactone (Aldactone)
Correct answer: B
Rationale: In heart failure with marked edema and low urine output, the nurse can expect the provider to order Furosemide (Lasix). Furosemide is a loop diuretic that acts quickly to remove excess fluid from the body, making it an appropriate choice for this patient's condition. Digoxin is used to improve heart function but does not directly address fluid overload. Hydrochlorothiazide is a thiazide diuretic that is not as potent as Furosemide in managing acute fluid retention. Spironolactone is a potassium-sparing diuretic that is typically used in heart failure for its aldosterone-blocking effects and not for immediate fluid removal.
