HESI LPN
Adult Health 2 Exam 1
1. The healthcare provider reviews the laboratory results of a client whose serum pH is 7.38. What does this value imply about the client's homeostasis?
- A. Alkalosis
- B. Acidosis
- C. Normal serum pH
- D. Incompatible with life
Correct answer: C
Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client’s acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.
2. While caring for a client who is being mechanically ventilated, the nurse responds to a high-pressure alarm on the ventilator. Which assessment finding warrants immediate intervention by the nurse?
- A. Endotracheal cuff pressure greater than 25 cm H2O.
- B. Decreased lung compliance during ventilation.
- C. Bilateral crackles with increased secretions.
- D. Restless client who is biting the endotracheal tube.
Correct answer: D
Rationale: A restless client biting the endotracheal tube can increase airway resistance, triggering the high-pressure alarm and indicating a need for immediate intervention. This behavior can lead to complications such as dislodgement of the tube or airway obstruction. Endotracheal cuff pressure greater than 25 cm H2O, decreased lung compliance, and bilateral crackles with increased secretions are important assessments but do not directly address the urgent need to intervene when a high-pressure alarm is triggered.
3. The nurse is caring for a 75-year-old male client who is beginning to form a decubitus ulcer at the coccyx. Which intervention will be most helpful in preventing further development of the decubitus ulcer?
- A. Encourage the client to eat foods high in protein
- B. Assess the client for daily range of motion exercises
- C. Teach the family how to perform sterile wound care
- D. Ensure the IV fluids are administered as prescribed
Correct answer: A
Rationale: Encouraging the client to eat foods high in protein is crucial in preventing further development of decubitus ulcers as high protein foods support tissue repair and skin integrity. Adequate protein intake is essential for wound healing. Assessing the client for daily range of motion exercises is important for preventing complications related to immobility, but it may not directly address the prevention of decubitus ulcers. Teaching the family how to perform sterile wound care is significant for wound management but may not be the most effective intervention to prevent further development of decubitus ulcers. Ensuring IV fluids are administered as prescribed is essential for maintaining hydration status but is not the most relevant intervention for preventing decubitus ulcers.
4. The nurse plans to evaluate the effectiveness of several drugs administered by different routes. Arrange the routes of administration from fastest to slowest rate of absorption. 1. Intravenous 2. Sublingual 3. Intramuscular 4. Subcutaneous
- A. 1,2,3,4
- B. 4,3,2,1
- C. 2,4,3,1
- D. 3,4,1,2
Correct answer: A
Rationale: The correct order of routes of administration from fastest to slowest rate of absorption is 1. Intravenous, 2. Sublingual, 3. Intramuscular, 4. Subcutaneous. Intravenous administration provides the fastest absorption as the drug is directly injected into the bloodstream. Sublingual administration allows for rapid absorption through the mucous membranes under the tongue. Intramuscular administration has a slower absorption rate as the drug is injected into the muscle tissue. Subcutaneous administration is the slowest as the drug is injected into the fatty tissue under the skin, leading to a slower absorption compared to the other routes.
5. A client is admitted with a diagnosis of congestive heart failure (CHF). Which intervention is most important to include in the plan of care?
- A. Restrict fluid intake
- B. Provide a high-sodium diet
- C. Encourage vigorous exercise
- D. Administer bronchodilators as prescribed
Correct answer: A
Rationale: The correct answer is A: Restrict fluid intake. Fluid restriction is crucial in the management of congestive heart failure (CHF) as it helps prevent fluid overload, which can exacerbate CHF symptoms. Choices B, C, and D are incorrect. Providing a high-sodium diet would worsen fluid retention and increase the workload of the heart. Encouraging vigorous exercise can strain the heart further in CHF patients. Administering bronchodilators is not the priority intervention for CHF.
