HESI Medical Surgical Assignment Exam
1. A patient is admitted to the hospital for treatment of pneumonia after complaining of high fever and shortness of breath. The patient was not able to produce sputum for a culture. The nurse will expect the patient’s provider to order
- A. a broad-spectrum antibiotic.
- B. a narrow-spectrum antibiotic.
- C. multiple antibiotics.
- D. the pneumococcal vaccine.
Correct answer: A
Rationale: In this scenario where the offending organism causing pneumonia is unknown due to the inability to produce sputum for culture, the appropriate choice is a broad-spectrum antibiotic. Broad-spectrum antibiotics are effective against a wide range of bacteria and are commonly used when the specific pathogen is unidentified. Narrow-spectrum antibiotics target specific types of bacteria and are chosen based on culture and sensitivity results. Using multiple antibiotics without a clear indication from culture and sensitivity testing can lead to antibiotic resistance and is not recommended in this situation. Additionally, the pneumococcal vaccine is preventive and does not treat an ongoing infection like pneumonia.
2. A client is to have a transsphenoidal hypophysectomy to remove a large, invasive pituitary tumor. The nurse should instruct the client that the surgery will be performed through an incision in the:
- A. Back of the mouth.
- B. Nose.
- C. Sinus channel below the right eye.
- D. Upper gingival mucosa in the space between the upper gums and lip.
Correct answer: D
Rationale: The correct answer is D: Upper gingival mucosa in the space between the upper gums and lip. A transsphenoidal hypophysectomy involves accessing the pituitary gland through an incision in the upper gingival mucosa, providing direct access to the pituitary gland without external scars. Choices A, B, and C are incorrect because the surgery is not performed through the back of the mouth, the nose, or the sinus channel below the right eye. It is crucial for the client to understand the specific location of the incision to ensure accurate preoperative education and expectations.
3. A client with elevated levels of antidiuretic hormone (ADH) triggers the release of this hormone due to which disorder?
- A. Pneumonia
- B. Dehydration
- C. Renal failure
- D. Edema
Correct answer: B
Rationale: Antidiuretic hormone (ADH) increases tubular permeability to water, causing more water absorption into the capillaries. ADH is released in response to a rising extracellular fluid osmolarity, such as in dehydration. Pneumonia, renal failure, and edema do not typically lead to the release of ADH. Pneumonia is an inflammatory lung condition, renal failure affects kidney function, and edema is the accumulation of excess fluid in the tissues, none of which directly stimulate the release of ADH.
4. Which of the following is the best position for a patient experiencing dyspnea?
- A. Supine position.
- B. Fowler's position.
- C. Trendelenburg position.
- D. Lateral recumbent position.
Correct answer: B
Rationale: Fowler's position is the best position for a patient experiencing dyspnea. This position involves sitting the patient upright with the head of the bed elevated between 45-60 degrees. Fowler's position helps improve breathing in patients with dyspnea by promoting lung expansion, aiding in better oxygenation, and reducing the work of breathing. The supine position (Choice A) may worsen dyspnea by limiting lung expansion. The Trendelenburg position (Choice C) with the feet elevated and the head down is not recommended for dyspnea as it can increase pressure on the chest and compromise breathing. The lateral recumbent position (Choice D) is not ideal for dyspnea as it does not provide optimal lung expansion and may not alleviate breathing difficulty.
5. A patient who is being treated for dehydration is receiving 5% dextrose and 0.45% normal saline with 20 mEq/L potassium chloride at a rate of 125 mL/hour. The nurse assuming care for the patient reviews the patient’s serum electrolytes and notes a serum sodium level of 140 mEq/L and a serum potassium level of 3.6 mEq/L. The patient had a urine output of 250 mL during the last 12-hour shift. Which action will the nurse take?
- A. Contact the patient’s provider to discuss increasing the potassium chloride to 40 mEq/L.
- B. Continue the intravenous fluids as ordered and reassess the patient frequently.
- C. Notify the provider and discuss increasing the rate of fluids to 200 mL/hour.
- D. Stop the intravenous fluids and notify the provider of the assessment findings.
Correct answer: D
Rationale: The patient’s potassium level is within normal limits, but the decreased urine output indicates the patient should not receive additional IV potassium. Increasing potassium chloride to 40 mEq/L is not needed as the level is normal. Stopping the IV fluids is appropriate due to the decreased urine output, which suggests potential fluid overload. The nurse should notify the provider of the assessment findings for further management. Increasing the rate of fluids to 200 mL/hour is not recommended without addressing the decreased urine output first.
