HESI Fundamentals Study Guide
1. A nurse is caring for a client who has a surgical wound. Which of the following laboratory values places the client at risk for poor wound healing?
- A. Serum albumin 3 g/dL
- B. Total lymphocyte count 2400/mm3
- C. HCT 42%
- D. HGB 16 g/dL
Correct answer: A
Rationale: The correct answer is A: Serum albumin 3 g/dL. Low levels of serum albumin indicate poor nutritional status and can impair wound healing. Total lymphocyte count, HCT, and HGB levels are not directly related to wound healing and do not pose a significant risk for poor wound healing in this context. Total lymphocyte count reflects the immune status, HCT measures the percentage of red blood cells in blood, and HGB measures the amount of hemoglobin in blood.
2. The patient has been brought to the emergency department following a motor vehicle accident. The patient is unresponsive. The driver's license states that glasses are needed to operate a motor vehicle, but no glasses were brought in with the patient. Which action should the nurse take next?
- A. Stand to the side of the patient's eye and observe the cornea.
- B. Conclude that the glasses were lost during the accident.
- C. Notify the ambulance personnel about the missing glasses.
- D. Ask the patient where the glasses are.
Correct answer: A
Rationale: In this scenario, the nurse should stand to the side of the patient's eye and observe the cornea. This action is crucial in assessing whether the patient wears contact lenses, especially in unresponsive patients. Observing the cornea can provide valuable information about the patient's eye health and potential use of contact lenses. Choices B, C, and D are incorrect. Concluding that the glasses were lost during the accident is premature without proper assessment. Notifying ambulance personnel about the missing glasses may not be the immediate priority, and asking the unresponsive patient about the glasses would not yield useful information in this situation.
3. When assessing a client’s heart sounds, the nurse hears a scratching sound during both systole and diastole. These sounds become more distinct when the nurse has the client sit up and lean forward. The nurse should document the presence of a:
- A. Pericardial friction rub
- B. Heart murmur
- C. S3 heart sound
- D. S4 heart sound
Correct answer: A
Rationale: A pericardial friction rub is characterized by a scratching sound that occurs during both systole and diastole. It becomes more distinct when the client is sitting up and leaning forward. This indicates an inflammation of the pericardial sac rubbing against the layers of the heart. Heart murmurs (choice B) are abnormal heart sounds caused by turbulent blood flow, not by friction like in a pericardial rub. S3 and S4 heart sounds (choices C and D) are additional heart sounds related to abnormal ventricular filling, not to pericardial friction rubs.
4. A client is having difficulty breathing while laying in bed with a nasal cannula delivering oxygen. Which of the following interventions should the nurse take first?
- A. Suction the client's airway
- B. Administer a bronchodilator
- C. Increase the humidity in the client's room
- D. Assist the client to an upright position
Correct answer: D
Rationale: The correct answer is to assist the client to an upright position. When a client is having difficulty breathing, promoting optimal oxygenation is essential. Elevating the head of the bed improves ventilation and lung expansion by reducing pressure on the diaphragm. This position allows the lungs to expand fully, enhancing oxygen exchange. Suctioning the airway may be necessary if there are secretions causing obstruction, but it is not the first intervention in this scenario. Administering a bronchodilator is appropriate for bronchoconstriction but does not address the immediate need for better ventilation. Increasing humidity can be beneficial in certain respiratory conditions, but it is not the initial priority when a client is struggling to breathe.
5. A patient's neighbor is scheduled for elective surgery. The neighbor’s provider indicated that a moderate amount of blood loss is expected during the surgery, and the neighbor is anxious about acquiring an infection from a blood transfusion. Which of the following is appropriate for the nurse to suggest?
- A. Avoid the blood transfusion
- B. Donate autologous blood before the surgery
- C. Use a blood substitute
- D. Take antibiotics before the surgery
Correct answer: B
Rationale: Donating autologous blood before surgery is an appropriate suggestion by the nurse. This process involves the patient donating their own blood before the surgery, which reduces the risk of infection from transfusions as the patient is receiving their own blood. Choice A is incorrect as avoiding the blood transfusion may not be feasible or safe in the context of expected blood loss during surgery. Choice C is not a common practice and may carry its own risks. Choice D is not directly related to reducing the risk of infection from a blood transfusion.
