Nursing Elites

1. The family of a newly admitted child with cystic fibrosis is educated by the nurse that the treatment will be centered on what therapy?

• A. Chest physiotherapy
• B. Mucus-drying agents
• C. Prevention of diarrhea
• D. Insulin therapy

Correct answer: A

Rationale: The correct answer is A: Chest physiotherapy. In cystic fibrosis, chest physiotherapy and aerosol medications are fundamental components of treatment to help clear mucus from the lungs, reduce the risk of infections, and improve breathing. Mucus-drying agents (Choice B) are not typically used in the treatment of cystic fibrosis. Prevention of diarrhea (Choice C) is not a primary focus in the treatment of cystic fibrosis. Insulin therapy (Choice D) is not relevant to cystic fibrosis, as it is a treatment for diabetes.

2. A client with hypertension is prescribed a low-sodium diet. Which food should the client avoid?

• A. Fresh fruits
• B. Processed cheese
• C. Whole grain bread
• D. Fresh vegetables

Correct answer: B

Rationale: The correct answer is B: Processed cheese. Processed cheese is high in sodium and should be avoided in a low-sodium diet for clients with hypertension. Fresh fruits, whole grain bread, and fresh vegetables are generally low in sodium and can be part of a healthy diet for clients with hypertension.

3. A male client with acquired immune deficiency syndrome (AIDS) and Pneumocystis carinii pneumonia has a CD4+ T cell count of 200 cells/microliter. The client asks the nurse why he keeps getting these massive infections. Which pathophysiologic mechanism should the nurse describe in response to the client's question?

• A. Bone marrow suppression of white blood cells causes insufficient cells to phagocytize organisms.
• B. Exposure to multiple environmental infectious agents overburdens the immune system until it fails.
• C. The humoral immune response lacks B cells that form antibodies and opportunistic infections result.
• D. Inadequate numbers of T lymphocytes are available to initiate cellular immunity and macrophages.

Correct answer: D

Rationale: With a CD4+ T cell count of 200 cells/microliter, the client's immune system is severely compromised, leading to opportunistic infections.

4. 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.

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.
