HESI Medical Surgical Specialty Exam
1. A patient taking trimethoprim-sulfamethoxazole (TMP-SMX) to treat a urinary tract infection complains of a sore throat. The nurse will contact the provider to request an order for which laboratory test(s)?
- A. Complete blood count with differential
- B. Throat culture
- C. Urinalysis
- D. Coagulation studies
Correct answer: A
Rationale: When a patient taking trimethoprim-sulfamethoxazole (TMP-SMX) for a urinary tract infection presents with a sore throat, the nurse should request a complete blood count with differential. TMP-SMX can cause life-threatening adverse effects such as agranulocytosis, a condition characterized by a low white blood cell count, which can manifest as a sore throat. Ordering a complete blood count with differential helps assess the patient's white blood cell count to detect any potential serious adverse effects. Throat culture (Choice B) is not indicated unless there are specific signs of a throat infection. Urinalysis (Choice C) is not relevant for assessing a sore throat. Coagulation studies (Choice D) are not typically indicated for a sore throat symptom.
2. Which is a characteristic that distinguishes sulfonamides from other drugs used to treat bacterial infections?
- A. Sulfonamides are bactericidal.
- B. Sulfonamides are synthetic compounds.
- C. Sulfonamides have antifungal and antiviral properties.
- D. Sulfonamides increase bacterial synthesis of folic acid.
Correct answer: B
Rationale: The characteristic that distinguishes sulfonamides from other drugs used to treat bacterial infections is that sulfonamides are synthetic compounds, not derived from biologic substances. Choice A is incorrect because sulfonamides are bacteriostatic, not bactericidal. Choice C is incorrect because sulfonamides do not have antifungal and antiviral properties. Choice D is incorrect because sulfonamides act by inhibiting bacterial synthesis of folic acid, not increasing it.
3. When performing a health history on a patient who is to begin receiving a thiazide diuretic to treat heart failure, the nurse will be concerned about a history of which condition?
- A. Asthma
- B. Glaucoma
- C. Gout
- D. Hypertension
Correct answer: C
Rationale: Thiazide diuretics block uric acid secretion, leading to elevated levels that can contribute to gout. Therefore, patients with a history of gout should take thiazide diuretics with caution. Asthma (Choice A), Glaucoma (Choice B), and Hypertension (Choice D) are not directly contraindicated with thiazide diuretics, making choices A, B, and D incorrect.
4. Which of the following symptoms would a healthcare provider expect to find in a patient with hyperkalemia?
- A. Muscle cramps.
- B. Hypertension.
- C. Bradycardia.
- D. Tachycardia.
Correct answer: D
Rationale: Tachycardia is the correct symptom to expect in a patient with hyperkalemia. Hyperkalemia, or high potassium levels in the blood, can affect the electrical activity of the heart. Increased potassium levels can lead to changes in the heart's rhythm, potentially causing tachycardia (rapid heart rate) or other cardiac arrhythmias. Muscle cramps (choice A) are not typically associated with hyperkalemia. Hypertension (choice B) is not a common symptom of hyperkalemia; in fact, high potassium levels can sometimes cause low blood pressure. Bradycardia (choice C), or a slow heart rate, is usually not a primary symptom of hyperkalemia; instead, hyperkalemia tends to be associated with faster heart rates or arrhythmias.
5. A client is receiving Cilostazol (Pletal) for peripheral arterial disease causing intermittent claudication. The nurse determines this medication is effective when the client reports which of the following?
- A. I am having fewer aches and pains.
- B. I do not have headaches anymore.
- C. I am able to walk further without leg pain.
- D. My toes are turning grayish black in color.
Correct answer: C
Rationale: The correct answer is C. Cilostazol improves blood flow to the muscles, which helps alleviate symptoms of intermittent claudication. An improvement in walking distance without leg pain indicates the effectiveness of the medication. Choices A and B are not directly related to the expected outcome of Cilostazol therapy for intermittent claudication. Choice D is concerning for a potential adverse effect and should be reported to the healthcare provider immediately.
