HESI LPN
Fundamentals HESI
1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the LPN/LVN monitor closely while the client is taking this medication?
- A. Blood glucose level
- B. Prothrombin time (PT) and INR
- C. Serum potassium level
- D. Serum creatinine level
Correct answer: B
Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.
2. Community health nurses help influence the health of communities through which of the following actions?
- A. legislating health behavior
- B. recording health status of individuals in a similar geographic region
- C. influencing health status and behavior, and engaging in health promotion
- D. none of the above
Correct answer: C
Rationale: Community health nurses play a crucial role in influencing the health of communities by engaging in health promotion activities and influencing health behaviors. Choice A is incorrect as community health nurses do not legislate health behavior but rather educate and promote healthy behaviors. Choice B is incorrect as while community health nurses may record health data, their main focus is on proactive health promotion and intervention, not just documenting health status. Choice D is incorrect because community health nurses actively work to influence health status and behaviors.
3. A client with type 1 diabetes mellitus is learning to administer insulin. What is the best site for the nurse to recommend for insulin injection?
- A. Abdomen
- B. Thigh
- C. Upper arm
- D. Buttock
Correct answer: A
Rationale: The correct answer is the abdomen. The abdomen is the recommended site for insulin injection due to its faster absorption rate compared to other sites. Insulin injected into the abdomen is absorbed more quickly, leading to better glycemic control. The thigh and upper arm are also common sites for insulin injection, but they have slower absorption rates than the abdomen. The buttock is not a preferred site for insulin injection due to inconsistent absorption and potential risk of injecting into muscle instead of fatty tissue.
4. The mother of a toddler calls the nurse for help as the baby is choking on his food. The nurse determines that the Heimlich maneuver is necessary based on which finding?
- A. Inability of the toddler to cry or speak
- B. Coughing forcefully
- C. Gagging but able to breathe
- D. Wheezing during respiration
Correct answer: A
Rationale: The correct answer is option A: Inability of the toddler to cry or speak. In cases of choking, the inability to cry or speak indicates a severe airway obstruction where the Heimlich maneuver is necessary to clear the obstruction and establish a patent airway. Option B, coughing forcefully, represents a partial obstruction where the child can still move air, making the Heimlich maneuver not immediately necessary. Option C, gagging but able to breathe, suggests a partial obstruction where air is moving, and the child can still breathe, not requiring immediate intervention like the Heimlich maneuver. Option D, wheezing during respiration, is more indicative of a lower airway issue such as asthma rather than an upper airway obstruction that necessitates the Heimlich maneuver.
5. The healthcare professional caring for a patient who is immobile frequently checks for impaired skin integrity. What is the rationale for this action?
- A. Inadequate blood flow leads to decreased tissue ischemia.
- B. Patients with limited caloric intake develop thicker skin.
- C. Pressure reduces circulation to affected tissue.
- D. Verbalization of skin care needs is decreased.
Correct answer: C
Rationale: The rationale behind checking for impaired skin integrity in an immobile patient is that pressure reduces circulation to the affected tissue. Prolonged pressure on specific body parts can lead to reduced blood flow to those areas, causing tissue damage and potentially leading to pressure ulcers. Choices A, B, and D are incorrect because inadequate blood flow causing decreased tissue ischemia, limited caloric intake leading to thicker skin, and decreased verbalization of skin care needs are not directly related to the rationale for checking for impaired skin integrity in immobile patients.
