HESI RN Medical Surgical Practice Exam
1. A patient has a serum potassium level of 2.7 mEq/L. The patient’s provider has determined that the patient will need 200 mEq of potassium to replace serum losses. How will the nurse caring for this patient expect to administer the potassium?
- A. As a single-dose 200 mEq oral tablet
- B. As an intravenous bolus over 15 to 20 minutes
- C. In an intravenous solution at a rate of 10 mEq/hour
- D. In an intravenous solution at a rate of 45 mEq/hour
Correct answer: C
Rationale: For a patient with severe hypokalemia with a serum potassium level of 2.7 mEq/L requiring 200 mEq of potassium replacement, the appropriate route of administration would be intravenous. Potassium chloride should be administered slowly to prevent adverse effects; therefore, the correct option is to administer the potassium in an intravenous solution at a rate of 10 mEq/hour. Choices A and B are incorrect because potassium should not be given as a single-dose oral tablet or as an intravenous bolus over a short period of time due to the risk of adverse effects. Choice D is also incorrect as the rate of 45 mEq/hour exceeds the recommended maximum infusion rate for adults with a serum potassium level greater than 2.5 mEq/L, which is 10 mEq/hour.
2. A client has undergone renal angiography via the right femoral artery. The nurse determines that the client is experiencing a complication of the procedure upon noting:
- A. Urine output of 40 mL/hr
- B. Blood pressure of 118/76 mm Hg
- C. Respiratory rate of 18 breaths/min
- D. Pallor and coolness of the right leg
Correct answer: D
Rationale: Pallor and coolness of the right leg indicate a potential vascular complication following renal angiography, such as hemorrhage, thrombosis, or embolism. These signs suggest impaired circulation in the affected limb. Urine output, blood pressure, and respiratory rate are not typically associated with complications of renal angiography. Complications of this procedure mainly involve allergic reactions to the dye, dye-induced renal damage, and various vascular issues.
3. The nurse is caring for several patients who are receiving antibiotics. Which order will the nurse question?
- A. Azithromycin (Zithromax) 500 mg IV in 500 mL of fluid
- B. Azithromycin (Zithromax) 500 mg PO once daily
- C. Erythromycin 300 mg IM QID
- D. Erythromycin 300 mg PO QID
Correct answer: C
Rationale: The nurse should question the order for Erythromycin 300 mg IM QID. Erythromycin and other macrolides should not be given intramuscularly because they cause painful tissue irritation. Options A and B are correct routes for Azithromycin, either intravenously or orally. Option D is a correct route for Erythromycin, which is orally.
4. The nurse instructs the unlicensed nursing personnel (UAP) on how to provide oral hygiene for clients who cannot perform this task for themselves. Which of the following techniques should the nurse tell the UAP to incorporate into the client's daily care?
- A. Assess the oral cavity each time mouth care is given and record observations.
- B. Use a soft toothbrush to brush the client's teeth after each meal.
- C. Swab the client's tongue, gums, and lips with a soft foam applicator every 2 hours.
- D. Rinse the client's mouth with mouthwash several times a day.
Correct answer: B
Rationale: The correct technique to incorporate into the client's daily care for oral hygiene is to use a soft toothbrush to brush the client's teeth after each meal. This helps in maintaining oral hygiene for clients who cannot perform this task themselves. Choice A is incorrect because assessing the oral cavity each time mouth care is given is important but not the technique to incorporate into daily care. Choice C is incorrect as swabbing the tongue, gums, and lips every 2 hours may not be necessary for daily care. Choice D is incorrect as rinsing the client's mouth with mouthwash several times a day may not be suitable for all clients and is not a standard recommendation for daily oral care.
5. The healthcare provider is unable to palpate the client's left pedal pulses. Which of the following actions should the healthcare provider take next?
- A. Auscultate the pulses with a stethoscope.
- B. Call the physician.
- C. Use a Doppler ultrasound device.
- D. Inspect the lower left extremity.
Correct answer: C
Rationale: When pedal pulses are not palpable, using a Doppler ultrasound device is the appropriate next step to locate the pulse. Auscultating the pulses with a stethoscope (Choice A) is used for assessing blood flow in arteries above the clavicle, not for pedal pulses. Calling the physician (Choice B) may be necessary at a later stage, but initially, using a Doppler ultrasound device to locate the pulse is more appropriate. Inspecting the lower left extremity (Choice D) can provide visual information but will not help in locating the pedal pulses, making it a less suitable option.
