A nurse is caring for a client who is hyperventilating and has the following ABG results: pH 7.50, PaCO2 29 mm Hg, and HCO3- 25 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct Answer: B
Rationale: The correct answer is B: Respiratory alkalosis. In this scenario, the client is experiencing respiratory alkalosis due to hyperventilation. Hyperventilation leads to excessive loss of carbon dioxide, causing a decrease in hydrogen ion concentration and an increase in pH levels. Choices A, C, and D are incorrect. Respiratory acidosis is characterized by high PaCO2 and low pH. Metabolic acidosis is associated with low HCO3- levels and low pH. Metabolic alkalosis is marked by high HCO3- levels and high pH. In this case, the ABG results indicate respiratory alkalosis.

A nurse in a rural community center is providing education to a group of clients about first aid interventions for snake bites. Which of the following instructions should the nurse include in the teaching?
- A. Apply an ice pack directly to the affected area
- B. Immobilize the affected extremity with a splint
- C. Place a tourniquet above and below the affected area
- D. Elevate the affected extremity
Correct Answer: B
Rationale: The correct answer is to immobilize the affected extremity with a splint. This helps to slow the spread of venom by limiting movement. Applying an ice pack directly to the affected area (Choice A) is not recommended for snake bites as it could exacerbate tissue damage. Placing a tourniquet above and below the affected area (Choice C) is also not advised as it can lead to further complications. Elevating the affected extremity (Choice D) is not recommended for snake bites; keeping it below the level of the heart is more appropriate to reduce venom spread.
A nurse is teaching a group of assistive personnel (AP) about caring for clients who have Alzheimer's disease. Which of the following information should the nurse include in the teaching?
- A. Explain procedures clearly and concisely to the client before initiating care
- B. Encourage a client's engagement in appropriate activities to minimize emotional outbursts
- C. Speak calmly and at a moderate volume to a client who is unable to form words or sentences
- D. Provide supervision to prevent a client from becoming injured or lost
Correct Answer: D
Rationale: The correct answer is D because clients with Alzheimer's disease are at risk of wandering and becoming lost. Providing supervision helps prevent them from getting injured or lost. Choice A is incorrect because extensive details may overwhelm clients with Alzheimer's. Choice B is incorrect because limiting activities can lead to boredom and behavioral issues. Choice C is incorrect because speaking calmly and at a moderate volume helps to reduce agitation and confusion in clients with Alzheimer's.
A healthcare professional is preparing a client for a colonoscopy. Which of the following medications should the professional anticipate the provider to prescribe as an anesthetic for the procedure?
- A. Propofol
- B. Pancuronium
- C. Promethazine
- D. Pentoxifylline
Correct Answer: A
Rationale: The correct answer is A, Propofol. Propofol is a short-acting anesthetic medication commonly used for procedures like colonoscopies to induce moderate sedation. Pancuronium (Choice B) is a neuromuscular blocking agent used as a paralyzing agent during surgery, not for sedation. Promethazine (Choice C) is an antihistamine often used for nausea and vomiting, not as an anesthetic. Pentoxifylline (Choice D) is a medication used to improve blood flow and is not indicated for anesthesia.
A healthcare provider is assessing a client who reports a possible exposure to HIV. Which of the following findings should the healthcare provider identify as an early manifestation of HIV infection?
- A. Stomatitis
- B. Fatigue
- C. Wasting syndrome
- D. Lipodystrophy
Correct Answer: B
Rationale: The correct answer is 'B: Fatigue.' Early manifestations of HIV infection often include symptoms like fatigue, fever, and rash, which are typical of viral infections. Stomatitis (choice A) refers to inflammation of the mouth and lips, which can occur in HIV but is not specific to early infection. Wasting syndrome (choice C) and lipodystrophy (choice D) are more commonly associated with later stages of HIV infection rather than early manifestations.
A nurse is developing a plan of care for a client who will be placed in halo traction following surgical repair of the cervical spine. Which of the following interventions should the nurse include in the plan?
- A. Inspect the pin site every 4 hours
- B. Monitor the client's skin under the halo vest
- C. Ensure two personnel hold the halo device when repositioning the client
- D. Apply powder to the client's skin under the vest to decrease itching
Correct Answer: B
Rationale: The correct answer is to monitor the client's skin under the halo vest. This is important to assess for signs of skin issues such as excessive sweating, redness, or blistering, which can lead to skin breakdown and infection. Choice A is incorrect because while inspecting the pin site is important, it should be done more frequently than every 4 hours. Choice C is incorrect as the halo device should be supported by the client's body weight, not personnel, when repositioning. Choice D is incorrect because applying powder frequently can increase the risk of skin irritation and infection.
