HESI Fundamentals Practice Exam
1. A client is admitted with a diagnosis of fluid volume deficit. Which clinical finding would the nurse expect?
- A. Bounding pulse
- B. Bradycardia
- C. Oliguria
- D. Dry mucous membranes
Correct answer: D
Rationale: Dry mucous membranes (D) are a common clinical finding indicating fluid volume deficit. In dehydration, there is insufficient fluid in the body, leading to dry mucous membranes due to decreased saliva production. Bounding pulse (A) is associated with fluid volume excess, not deficit. Bradycardia (B) and oliguria (C) are not typical clinical findings of fluid volume deficit but may be seen in fluid volume excess or other conditions.
2. A client with a diagnosis of asthma is receiving albuterol (Proventil) via a metered-dose inhaler (MDI). Which assessment finding indicates that the medication is effective?
- A. Increased oxygen saturation.
- B. Decreased respiratory rate.
- C. Absence of audible wheezing.
- D. Improved exercise tolerance.
Correct answer: A
Rationale: Increased oxygen saturation (A) is the most direct indicator of the effectiveness of albuterol (Proventil) in improving breathing. Oxygen saturation reflects the amount of oxygen in the blood, showing that the albuterol is helping with air exchange in the lungs. While decreased respiratory rate (B), absence of audible wheezing (C), and improved exercise tolerance (D) are positive outcomes, they are secondary to oxygen saturation. Oxygen saturation directly reflects the improvement in the client's respiratory status and the effectiveness of the medication.
3. When assessing a client with wrist restraints, the nurse observes that the fingers on the right hand are blue. What action should the nurse implement first?
- A. Loosen the right wrist restraint.
- B. Apply a pulse oximeter to the right hand.
- C. Compare hand color bilaterally.
- D. Palpate the right radial pulse.
Correct answer: A
Rationale: The priority nursing action is to restore circulation by loosening the restraint (A) because blue fingers (cyanosis) indicate decreased circulation. Comparing hand color bilaterally (C) and palpating the right radial pulse (D) are important assessments to gather more information, but they do not have the priority of addressing the decreased circulation by loosening the restraint. Applying a pulse oximeter (B) is not indicated in this scenario as it measures the saturation of hemoglobin with oxygen, which is not relevant when cyanosis is related to mechanical compression from the restraints.
4. By rolling contaminated gloves inside-out, the healthcare professional is affecting which step in the chain of infection?
- A. Mode of transmission
- B. Portal of entry
- C. Reservoir
- D. Portal of exit
Correct answer: A
Rationale: When contaminated gloves are rolled inside-out, they are serving as a mode of transmission by carrying pathogens from the reservoir's portal of exit to a new portal of entry. This action increases the risk of transmitting infections from one person to another, emphasizing the importance of proper glove removal techniques to prevent the spread of pathogens. Choices B, C, and D are incorrect in this context. Portal of entry refers to the route through which a pathogen enters a susceptible host, reservoir is the habitat where the pathogen lives, grows, and multiplies, and portal of exit is the path through which a pathogen leaves its host.
5. When culturing a wound, the nurse should obtain the sample from which part of the wound?
- A. The outer edges of the wound.
- B. All necrotic sections of the wound.
- C. Areas containing purulent or pooled exudates.
- D. Any particularly painful area of the wound.
Correct answer: C
Rationale: To collect a wound culture, the nurse should first clean the wound to remove skin flora and then insert a sterile swab from a culturette tube into the wound secretions.
