1. What is the primary treatment for a child with an anaphylactic reaction?
- A. Oral antihistamines
- B. Intravenous fluids
- C. Epinephrine injection
- D. Antipyretics
Correct answer: C
Rationale: The correct answer is C: Epinephrine injection. An epinephrine injection is the primary treatment for an anaphylactic reaction in children. Epinephrine acts quickly to reverse severe symptoms such as difficulty breathing, low blood pressure, and hives. Oral antihistamines, although useful for milder allergic reactions, are not sufficient to manage the potentially life-threatening symptoms of anaphylaxis. Intravenous fluids may be necessary to support blood pressure in a child with anaphylaxis but are not the primary treatment. Antipyretics, on the other hand, are medications used to reduce fever and are not indicated as the primary treatment for an anaphylactic reaction.
2. The settings on a client's synchronized intermittent mandatory ventilation (SIMV) are respiratory rate 12 breaths/minute, tidal volume at 600 mL, FiO2 35%, and positive end-expiratory pressure (PEEP) 5 cm H2O. Which assessment finding necessitates immediate intervention by the nurse?
- A. Bilateral crackles in the lung bases.
- B. Low-pressure indicator alarm.
- C. Oxygen saturation of 91%.
- D. Respiratory rate of 18 breaths/minute.
Correct answer: B
Rationale: A low-pressure alarm may indicate a disconnection or leak in the system, which needs immediate intervention. Bilateral crackles in the lung bases may indicate fluid overload but do not require immediate intervention in this case. An oxygen saturation of 91% is concerning but not as urgent as a potential equipment issue. A respiratory rate of 18 breaths/minute is higher than the set rate but may not necessitate immediate intervention unless accompanied by other distress symptoms.
3. The patient refuses to bathe in the morning, stating a preference for evening baths. What is the best action for the nurse?
- A. Defer the bath until evening and pass on the information to the next shift.
- B. Tell the patient that daily morning baths are part of the 'normal' routine.
- C. Explain the importance of maintaining morning hygiene practices.
- D. Cancel hygiene for the day and attempt again in the morning.
Correct answer: A
Rationale: The best action by the nurse is to respect the patient's preference and autonomy. Defer the bath until evening to allow the patient to follow their usual hygiene routine. Passing on the information to the next shift ensures continuity of care. Choice B is incorrect because it disregards the patient's preference and autonomy. Choice C, while important, does not address the patient's immediate concern. Choice D is incorrect as it does not respect the patient's wishes and may lead to further resistance to bathing.
4. A 25-year-old female client has been particularly restless, and the nurse finds her trying to leave the psychiatric unit. She tells the nurse, 'Please let me go! I must leave because the secret police are after me.' Which response is best for the nurse to make?
- A. No one is after you; you're safe here.
- B. You'll feel better after you have rested.
- C. I know you must feel lonely and frightened.
- D. Come with me to your room, and I will sit with you.
Correct answer: D
Rationale: In this scenario, the best response for the nurse is to offer presence and a safe environment without validating the delusion or arguing with the client. By inviting the client to the room and offering to sit with her, the nurse is providing support and reassurance. Choice A is incorrect because directly denying the client's belief may escalate the situation. Choice B is inappropriate as it dismisses the client's concerns without addressing the underlying issue. Choice C acknowledges the client's feelings but does not provide immediate support or safety, unlike Choice D which offers both.
5. A client with a history of chronic renal failure is admitted with generalized edema. Which laboratory value should the LPN/LVN monitor to assess the client's fluid balance?
- A. Serum potassium
- B. Serum calcium
- C. Serum albumin
- D. Serum sodium
Correct answer: C
Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.
