1. An adult client who received partial-thickness and full-thickness burns over 40% of the body in a house fire is admitted to the inpatient burn unit.
- A. Normal Saline
- B. Lactated Ringer’s
- C. 5% Dextrose in water
- D. 0.45% Sodium Chloride
Correct answer: B
Rationale: In burn patients, Lactated Ringer's solution is preferred over other options as it helps in restoring fluid and electrolyte balance effectively. Lactated Ringer's contains electrolytes (sodium, potassium, calcium) that closely mimic the body's natural composition, making it a suitable choice for fluid resuscitation in burn injuries. Normal Saline (Choice A) lacks electrolytes like potassium and calcium, which are essential in burn management. 5% Dextrose in water (Choice C) is a hypotonic solution and is not the ideal choice for fluid resuscitation in burn patients. 0.45% Sodium Chloride (Choice D) is a hypotonic solution mainly used for conditions requiring free water replacement rather than volume expansion needed in burn injuries.
2. How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?
- A. They involve antigen-antibody complexes.
- B. They are mediated by T cells and do not involve antibodies.
- C. They result in immediate allergic reactions.
- D. They are the least severe form of hypersensitivity.
Correct answer: B
Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.
3. A client with AIDS has impaired gas exchange from a respiratory infection. Which assessment finding warrants immediate intervention by the nurse?
- A. Elevated temperature
- B. Generalized weakness
- C. Diminished lung sounds
- D. Pain when swallowing
Correct answer: D
Rationale: In a client with AIDS and impaired gas exchange from a respiratory infection, pain when swallowing can indicate esophageal involvement, such as esophagitis or an esophageal infection like candidiasis. These conditions can significantly impact the client's ability to take in nutrition and medications, leading to complications like dehydration and malnutrition. Therefore, immediate intervention is required to address the underlying cause and prevent further complications. Elevated temperature (choice A) may indicate infection but does not directly address the impaired gas exchange. Generalized weakness (choice B) and diminished lung sounds (choice C) are concerning but do not directly relate to the immediate need for intervention in the context of esophageal involvement in a client with impaired gas exchange.
4. A client who has a history of hyperthyroidism was initially admitted with lethargy and confusion. Which additional finding warrants the most immediate action by the nurse?
- A. Facial puffiness and periorbital edema
- B. Hematocrit of 30%
- C. Cold and dry skin
- D. Further decline in LOC
Correct answer: D
Rationale: A further decline in LOC can indicate severe complications and requires immediate attention. This change may signify worsening neurological status, which could lead to life-threatening consequences if not addressed promptly. Choices A, B, and C may also be concerning in a client with a history of hyperthyroidism, but a further decline in LOC takes priority due to its potential for rapid deterioration and the need for urgent intervention.
5. A new mother asks the clinic nurse if she must continue giving her baby nystatin for thrush since the white lesions on his tongue have disappeared. What response by the nurse is most appropriate?
- A. No. When the lesions have disappeared, you may stop the nystatin.
- B. Yes. You should continue it for the full 7 days.
- C. No. Thrush is a self-limiting disorder, and nystatin is given for complete treatment.
- D. Yes. The medication should be refilled for a second week of therapy.
Correct answer: B
Rationale: The correct answer is B because nystatin should be given for the full 7 days even if the lesions are no longer present. Continuing the treatment for the prescribed duration ensures complete eradication of the fungal infection. Choice A is incorrect as stopping the medication prematurely may lead to the reoccurrence of thrush. Choice C is inaccurate as nystatin is not just for comfort but for effective treatment. Choice D is incorrect as refilling the medication for a second week without medical advice may lead to unnecessary prolonged use and potential side effects.
