HESI Medical Surgical Specialty Exam
1. A confused client with pneumonia is admitted with an indwelling catheter in place. During interdisciplinary rounds the following day, which question should the nurse ask the primary health care provider?
- A. Do you want daily weights on this client?
- B. Will the client be able to return home?
- C. Can we discontinue the indwelling catheter?
- D. Should we get another chest x-ray today?
Correct answer: C
Rationale: An indwelling catheter dramatically increases the risks of urinary tract infection and urosepsis. Nursing staff should ensure that catheters are left in place only as long as they are medically needed. The nurse should inquire about removing the catheter. All other questions might be appropriate, but because of client safety, this question takes priority.
2. A patient’s serum osmolality is 305 mOsm/kg. Which term describes this patient’s body fluid osmolality?
- A. Iso-osmolar
- B. Hypo-osmolar
- C. Hyperosmolar
- D. Isotonic
Correct answer: C
Rationale: The correct term to describe a patient with a serum osmolality of 305 mOsm/kg is 'hyperosmolar.' Normal osmolality ranges from 280 to 300 mOsm/kg. A patient with an osmolality above this range is considered hyperosmolar. Choice A ('Iso-osmolar') implies an equal osmolality, which is not the case in this scenario. Choice B ('Hypo-osmolar') suggests a lower osmolality, which is incorrect based on the provided serum osmolality value. Choice D ('Isotonic') refers to a solution having the same osmolality as another solution, not describing the specific scenario of this patient being above the normal range.
3. The nurse is providing teaching to a patient who will begin taking a cephalosporin to treat an infection. Which statement by the patient indicates a need for further teaching?
- A. I may stop taking the medication if my symptoms clear up.
- B. I should eat yogurt while taking this medication.
- C. I should stop taking the drug and call my provider if I develop a rash.
- D. I will not consume alcohol while taking this medication.
Correct answer: A
Rationale: Patients should take all of an antibiotic regimen even after symptoms clear to ensure complete treatment of the infection.
4. The nurse is preparing to administer the first dose of hydrochlorothiazide (HydroDIURIL) 50 mg to a patient who has a blood pressure of 160/95 mm Hg. The nurse notes that the patient had a urine output of 200 mL in the past 12 hours. The nurse will perform which action?
- A. Administer the medication as ordered.
- B. Encourage the patient to drink more fluids.
- C. Hold the medication and request an order for serum BUN and creatinine.
- D. Request an order for serum electrolytes and administer the medication.
Correct answer: C
Rationale: The correct action is to hold the medication and request an order for serum BUN and creatinine. Thiazide diuretics, such as hydrochlorothiazide, are contraindicated in renal failure. In this case, the patient has oliguria, which is a reduced urine output, indicating potential renal insufficiency. Before administering the diuretic, it is crucial to evaluate the patient's renal function through serum BUN and creatinine levels. Encouraging the patient to drink more fluids (Choice B) may not address the underlying issue of renal function. Administering the medication as ordered (Choice A) without assessing renal function can be harmful. Requesting serum electrolytes and administering the medication (Choice D) overlooks the need for a specific evaluation of renal function in this scenario.
5. The healthcare provider caring for a patient who will receive penicillin to treat an infection asks the patient about previous drug reactions. The patient reports having had a rash when taking amoxicillin (Amoxil). The healthcare provider will contact the provider to
- A. discuss giving a smaller dose of penicillin.
- B. discuss using erythromycin (E-mycin) instead of penicillin.
- C. request an order for diphenhydramine (Benadryl).
- D. suggest that the patient receive cefuroxime (Ceftin).
Correct answer: B
Rationale: When a patient reports a previous rash with amoxicillin, which is a type of penicillin, there is a concern for a penicillin allergy. In such cases, using an alternative antibiotic like erythromycin, which is not a penicillin, is the appropriate approach to avoid potential cross-reactivity and allergic reactions. Giving smaller doses of penicillin does not address the underlying allergy issue and can still lead to severe hypersensitivity reactions. Diphenhydramine (Benadryl) is used to manage allergic reactions but should not be the first choice in changing the antibiotic. While some patients allergic to penicillins may also be allergic to cephalosporins like cefuroxime, it is not the best immediate alternative in this scenario.
