HESI Medical Surgical Assignment Exam
1. A nurse is teaching a nursing student how to measure a carotid pulse. The nurse should tell the student to measure the pulse on only one side of the client’s neck primarily because:
- A. It is unnecessary to use both hands
- B. Feeling dual pulsations may lead to an incorrect measurement
- C. Palpating both carotid pulses simultaneously could occlude the trachea
- D. Palpating both carotid pulses simultaneously could cause the heart rate and blood pressure to drop
Correct answer: D
Rationale: The correct answer is D. Applying pressure to both carotid arteries at the same time is contraindicated. Excess pressure to the baroreceptors in the carotid vessels could cause the heart rate and blood pressure to reflexively drop. Palpating both carotid pulses simultaneously could also interfere with the flow of blood to the brain, possibly causing dizziness and syncope. Choices A, B, and C are incorrect. It is necessary to use both hands to measure the carotid pulse accurately. Feeling dual pulsations does not lead to an incorrect measurement, and palpating both carotid pulses simultaneously does not occlude the trachea.
2. A healthcare professional caring for a client who has been receiving intravenous diuretics suspects that the client is experiencing a deficient fluid volume. Which assessment finding would the healthcare professional note in a client with this condition?
- A. Lung congestion
- B. Decreased hematocrit
- C. Increased blood pressure
- D. Decreased central venous pressure (CVP)
Correct answer: D
Rationale: Decreased central venous pressure (CVP) is the correct assessment finding in a client with deficient fluid volume. This is because a decrease in CVP indicates reduced blood volume returning to the heart, which is consistent with hypovolemia. Lung congestion (Choice A) would be more indicative of fluid volume excess, not deficiency. Decreased hematocrit (Choice B) may be seen in conditions such as anemia but is not specific to deficient fluid volume. Increased blood pressure (Choice C) is not typically associated with deficient fluid volume; in fact, hypovolemia often leads to decreased blood pressure.
3. Why is the combination drug trimethoprim-sulfamethoxazole (TMP-SMX) necessary?
- A. To broaden the antibacterial spectrum.
- B. To decrease bacterial resistance.
- C. To improve the taste.
- D. To minimize toxic effects.
Correct answer: B
Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.
4. A 17-year-old female is seen in the school clinic for an evaluation of abdominal pain and dysmenorrhea. The client's last menstrual period was 3 weeks ago, and her vital signs are within normal limits. Which action should the nurse take first?
- A. Refer the client to a healthcare provider for a pelvic examination
- B. Notify the parents that the client needs to be picked up from school
- C. Determine the date of the client's last menstrual period
- D. Ask the client to lie down for a pelvic examination
Correct answer: A
Rationale: The correct action the nurse should take first is to refer the client to a healthcare provider for a pelvic examination. This is important to rule out serious conditions that may be causing the abdominal pain and dysmenorrhea. While notifying the parents, determining the date of the client's last menstrual period, and asking the client to lie down for a pelvic examination could be necessary steps, the priority is to ensure a proper evaluation by a healthcare provider to address the client's presenting symptoms effectively.
5. The nurse is planning a health education program for 10-year-olds. Which setting is most likely to increase the preadolescents' participation in the program?
- A. the school classroom
- B. community center
- C. home of one of the children
- D. a local place of worship
Correct answer: A
Rationale: The school classroom is the most suitable setting to increase preadolescents' participation in a health education program. At the age of 10, children are accustomed to the school environment, making it familiar and comfortable for them. This familiarity can help reduce anxiety and increase engagement during the program. Community centers may be less familiar and could pose distractions, potentially reducing participation. Conducting the program at the home of one of the children may lead to unequal access for other participants and may not provide the necessary facilities for an educational session. A local place of worship may not be perceived as a neutral or suitable environment for a health education program, potentially hindering participation.
