HESI PN Exit Exam 2024
1. While caring for a client with a new tracheostomy, the nurse notices that the client is attempting to speak but is unable to. What should the nurse explain to the client regarding their inability to speak?
- A. Speaking is not possible because the tracheostomy tube blocks the vocal cords.
- B. The tracheostomy tube prevents air from reaching the vocal cords, making speech difficult.
- C. The client will regain the ability to speak once the tracheostomy tube is removed.
- D. The tracheostomy tube must be replaced with a speaking valve for the client to speak.
Correct answer: B
Rationale: The correct answer is B. The tracheostomy tube bypasses the vocal cords, preventing air from reaching them, which is necessary for speech. This makes speaking difficult but not impossible. Removing the tracheostomy tube does not automatically restore the ability to speak (choice C). While a speaking valve can be added later to allow speech, initially, the tracheostomy tube itself hinders air from reaching the vocal cords, making speech difficult (choice D is incorrect). Choice A is incorrect as the tracheostomy tube does not block the vocal cords directly; instead, it prevents air from reaching them.
2. A client is complaining of a tingling sensation in the fingers, nose tip, and earlobes 24 hours after a total thyroidectomy. Which measure should the PN implement first?
- A. Apply sequential compression devices bilaterally
- B. Initiate prescribed L-thyroxine replacement therapy
- C. Obtain prescribed calcium gluconate for tetany
- D. Prepare for emergency tracheotomy at the bedside
Correct answer: C
Rationale: The correct answer is C: Obtain prescribed calcium gluconate for tetany. Tingling sensations post-thyroidectomy may indicate hypocalcemia, a potential complication that requires prompt treatment with calcium gluconate to prevent tetany. Initiating L-thyroxine replacement therapy (choice B) is important but not the first priority in this situation. Applying sequential compression devices (choice A) is not indicated for tingling sensations and does not address the potential complication of hypocalcemia. Preparing for an emergency tracheotomy (choice D) is not warranted based on the client's symptoms of tingling sensations.
3. What is the primary function of hemoglobin in red blood cells?
- A. Oxygen transport
- B. Immunity
- C. Blood clotting
- D. Carbon dioxide transport
Correct answer: A
Rationale: The correct answer is A: Oxygen transport. Hemoglobin in red blood cells binds to oxygen in the lungs and carries it to tissues throughout the body, releasing it where needed. This process is essential for cellular respiration and energy production. Choices B, C, and D are incorrect because hemoglobin's primary function is not related to immunity, blood clotting, or carbon dioxide transport. Hemoglobin's main role is to transport oxygen, ensuring adequate oxygen supply to body tissues for metabolic processes.
4. An adult female client with type 1 diabetes mellitus is receiving NPH insulin 35 units in the morning. Which finding should the nurse document as evidence that the amount of insulin is inadequate?
- A. States that her feet are constantly cold and numb
- B. A wound on the ankle that starts to drain and becomes painful
- C. Consecutive evening serum glucose greater than 260 mg/dL
- D. Reports nausea in the morning but still able to eat breakfast
Correct answer: C
Rationale: The correct answer is C. Consistently high evening glucose levels indicate that the current insulin dosage is inadequate to maintain proper glucose control. Choice A is incorrect because cold and numb feet are more indicative of peripheral vascular disease rather than inadequate insulin dosage. Choice B describes a wound that may be related to poor circulation or neuropathy but not necessarily inadequate insulin dosage. Choice D suggests gastrointestinal issues that are not directly related to insulin dosage adequacy.
5. Which electrolyte imbalance is most commonly associated with seizures?
- A. Hyponatremia
- B. Hypercalcemia
- C. Hyperkalemia
- D. Hypokalemia
Correct answer: A
Rationale: The correct answer is A: Hyponatremia. Hyponatremia, characterized by low sodium levels in the blood, can lead to cerebral edema and seizures due to water shifting into brain cells. Hypercalcemia (choice B) does not commonly cause seizures but can result in muscle weakness and cardiac arrhythmias. Hyperkalemia (choice C) may lead to muscle weakness and cardiac arrhythmias, but it is less frequently associated with seizures. Hypokalemia (choice D) is linked to muscle weakness and cardiac arrhythmias but is not typically related to seizures.
