HESI LPN
HESI CAT Exam 2024
1. An older male client with a history of type 1 diabetes has not felt well for the past few days and arrives at the clinic with abdominal cramping and vomiting. He is lethargic, moderately confused, and cannot remember when he took his last dose of insulin or ate last. What action should the nurse implement first?
- A. obtain a serum potassium level
- B. administer the client's usual dose of insulin
- C. assess pupillary response to light
- D. Start an intravenous (IV) infusion of normal saline
Correct answer: D
Rationale: Administering IV fluids is crucial to address potential dehydration and electrolyte imbalances, especially if the client is unable to provide a clear history. Starting an IV infusion of normal saline will help rehydrate the client and address any electrolyte imbalances, which are common in clients with diabetes experiencing symptoms like abdominal cramping and vomiting. Obtaining a serum potassium level can be important but is not the priority when the client is showing signs of dehydration and confusion. Administering insulin should only be done after addressing hydration and electrolyte status. Assessing pupillary response to light is not the most critical action in this situation compared to addressing dehydration and potential electrolyte imbalances.
2. What is the primary function of hemoglobin in red blood cells?
- A. To transport oxygen from the lungs to body tissues
- B. To protect the body from infections
- C. To help in blood clotting
- D. To regulate body temperature
Correct answer: A
Rationale: The primary function of hemoglobin in red blood cells is to transport oxygen from the lungs to body tissues and return carbon dioxide from the tissues to the lungs. Hemoglobin binds to oxygen in the lungs and releases it in the body's tissues. Choice B is incorrect because hemoglobin is not involved in protecting the body from infections. Choice C is incorrect because blood clotting is mainly facilitated by platelets and clotting factors, not hemoglobin. Choice D is incorrect because the regulation of body temperature is mainly controlled by processes like sweating and shivering, not by hemoglobin.
3. A client with type 1 diabetes mellitus is experiencing hypoglycemia. What is the best initial action for the LPN/LVN to take?
- A. Administer glucagon intramuscularly.
- B. Give the client 4 ounces of orange juice.
- C. Give the client a snack containing protein and carbohydrates.
- D. Encourage the client to rest until symptoms resolve.
Correct answer: B
Rationale: The best initial action for a client with type 1 diabetes mellitus experiencing hypoglycemia is to give them 4 ounces of orange juice. Orange juice quickly raises blood glucose levels in a hypoglycemic client. Administering glucagon intramuscularly is not the best initial action for hypoglycemia; it is usually reserved for severe hypoglycemia cases. Giving a snack containing protein and carbohydrates is not as rapid as orange juice in raising blood glucose levels during hypoglycemia. Encouraging the client to rest until symptoms resolve does not address the immediate need to raise blood glucose levels in a hypoglycemic state.
4. A 45-year-old female client is admitted to the psychiatric unit for evaluation. Her husband states that she has been reluctant to leave home for the last six months. The client has not gone to work for a month and has been terminated from her job. She has not left the house since that time. This client is displaying symptoms of what condition?
- A. Claustrophobia
- B. Acrophobia
- C. Agoraphobia
- D. Post-traumatic stress disorder
Correct answer: C
Rationale: The correct answer is C: Agoraphobia. Agoraphobia is the fear of crowds or being in open places, often leading individuals to avoid situations where they feel trapped, insecure, or out of control. In the case described, the client's reluctance to leave home, avoidance of work, and isolation within the house are indicative of agoraphobia. Claustrophobia (A) is the fear of closed places, while acrophobia (B) is the fear of high places. Post-traumatic stress disorder (D) involves the development of anxiety symptoms following a traumatic event, characterized by terror, fear, and helplessness, and is different from a phobia.
5. A client with obsessive-compulsive disorder (OCD) is hospitalized for treatment. Which intervention is most important for the LPN/LVN to include in the client's plan of care?
- A. Allow the client to engage in compulsive behaviors as a way to reduce anxiety.
- B. Encourage the client to ignore the compulsive behaviors.
- C. Help the client to understand the purpose of compulsive behaviors.
- D. Work with the client to gradually reduce the frequency of compulsive behaviors.
Correct answer: D
Rationale: The correct intervention for a client with OCD is to work with them to gradually reduce the frequency of compulsive behaviors. This approach helps the client manage their condition effectively without causing undue distress. Allowing the client to engage in compulsive behaviors can reinforce the disorder rather than alleviate it. Encouraging the client to ignore compulsive behaviors does not address the core issue of OCD. While helping the client understand the purpose of compulsive behaviors can be beneficial, actively working to reduce these behaviors is more crucial in the treatment of OCD.
