Nursing Elites

1. Which instruction should the nurse provide a client who was recently diagnosed with Raynaud's disease?

• A. Avoid cold temperatures completely.
• B. Take medications only during flare-ups.
• C. Wear gloves when removing packages from the freezer.
• D. Limit physical activity to avoid stress.

Correct answer: C

Rationale: The correct instruction for a client with Raynaud's disease is to wear gloves when handling cold items to prevent vasospasm. Raynaud's disease is characterized by vasospasm in response to cold or stress, leading to reduced blood flow to extremities. Wearing gloves when removing packages from the freezer helps minimize exposure to cold temperatures and can prevent triggering vasospasms. Choices A, B, and D are incorrect. Avoiding cold temperatures completely is impractical and may not always be possible. Taking medications only during flare-ups does not address prevention strategies, and limiting physical activity to avoid stress is not a primary intervention for Raynaud's disease.

2. The nurse is caring for a newborn with a myelomeningocele. Before surgery, what should the nursing interventions include?

• A. Leaving the lesion uncovered and placing the infant supine
• B. Covering the lesion with a sterile, saline-soaked gauze
• C. Applying lotion to the lesion to keep it moist
• D. Covering the lesion with a dry, sterile gauze

Correct answer: B

Rationale: The correct intervention before surgery for a newborn with a myelomeningocele is to cover the lesion with a sterile, saline-soaked gauze. This helps protect the exposed spinal cord and meninges from infection and damage. Choice A is incorrect because leaving the lesion uncovered can increase the risk of infection. Choice C is incorrect because applying lotion can introduce contaminants to the lesion. Choice D is incorrect because covering the lesion with a dry gauze can lead to adherence of the gauze to the wound, causing trauma upon removal and disrupting the healing process.

3. How often should the casts be changed for a newborn with talipes who is wearing casts?

• A. Daily
• B. Weekly
• C. Biweekly
• D. Monthly

Correct answer: B

Rationale: The correct answer is B: Weekly. Treatment of talipes involves manipulation and applying short leg casts. The casts need to be changed weekly to allow for further manipulation and to accommodate the rapid growth of the infant. Changing the casts daily (choice A) would be too frequent and may not provide enough time for the correction to take place. Changing the casts biweekly (choice C) or monthly (choice D) would not provide adequate support for the ongoing correction process required for talipes.

4. 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.

5. What most influences the severity of respiratory distress syndrome (RDS)?

• A. Poor cough and gag reflex
• B. The gestational age at birth
• C. Administering high concentrations of oxygen
• D. The sex of the infant

Correct answer: B

Rationale: The correct answer is B. The gestational age at birth most influences the severity of respiratory distress syndrome (RDS). RDS is caused by a deficiency of surfactant and it occurs almost exclusively in preterm, low-birth weight infants. Therefore, the gestational age at birth is a key factor in determining the likelihood and severity of RDS. Choices A, C, and D are incorrect as they do not directly relate to the primary factor influencing the severity of RDS.
