Nursing Elites

1. Which type of lymphocyte recognizes and eliminates virus-infected cells and cancerous cells?

• A. Neutrophils
• B. Macrophages
• C. Natural killer cells
• D. Langerhans cells

Correct answer: C

Rationale: Natural killer cells are a type of lymphocyte that plays a crucial role in recognizing and eliminating virus-infected cells and cancerous cells. Neutrophils (Choice A) are a type of white blood cell involved in fighting infections, mainly through phagocytosis. Macrophages (Choice B) are another type of white blood cell that engulfs and digests cellular debris and pathogens. Langerhans cells (Choice D) are a type of dendritic cell found in the skin and mucosa, primarily involved in antigen presentation.

2. What adverse effect should the nurse monitor for during testosterone therapy in a male patient?

• A. Increased risk of cardiovascular events
• B. Increased risk of liver dysfunction
• C. Increased risk of prostate cancer
• D. Increased risk of bone fractures

Correct answer: A

Rationale: The correct answer is A: Increased risk of cardiovascular events. Testosterone therapy can lead to an increased risk of cardiovascular events, such as heart attacks and strokes. This is why nurses should monitor for signs and symptoms of cardiovascular issues during therapy. Choices B, C, and D are incorrect because testosterone therapy is not typically associated with an increased risk of liver dysfunction, prostate cancer, or bone fractures. It is crucial for nurses to prioritize cardiovascular monitoring in patients receiving testosterone therapy.

3. An older adult man has moved to a long-term care facility, and the nurse is performing medication reconciliation. The resident's current medication regimen includes alfuzosin (Uroxatral). After considering the most likely indication for this drug, what potential problem should the nurse include in the resident's interdisciplinary plan of care?

• A. Impaired urinary elimination
• B. Ineffective sexual pattern
• C. Sexual dysfunction
• D. Functional urinary incontinence

Correct answer: C

Rationale: The correct answer is C, 'Sexual dysfunction.' Alfuzosin is commonly prescribed for benign prostatic hyperplasia (BPH), a condition that can lead to sexual dysfunction in older men. It is important to include this potential problem in the interdisciplinary plan of care to address the impact of the medication on the resident's sexual health. Choices A, B, and D are incorrect because while alfuzosin can affect urinary function, the primary concern related to this medication in this scenario is sexual dysfunction due to its indication for BPH.

4. In addition to matching ABO antigens, a blood transfusion must also be matched for:

• A. HLA type
• B. Rh antigen
• C. Immunoglobulins
• D. Platelet compatibility

Correct answer: B

Rationale: The correct answer is B: Rh antigen. In addition to ABO antigens, Rh antigen must also be matched for a blood transfusion. Rh antigen compatibility is crucial to prevent adverse reactions. Choice A, HLA type, is not directly related to blood transfusions but plays a role in organ transplantation. Choice C, Immunoglobulins, are not typically matched for blood transfusions. Choice D, Platelet compatibility, while important in specific cases, is not a standard requirement for all blood transfusions.

5. A tension pneumothorax requires a needle thoracostomy and/or chest tube placement as treatment to which component of the pathophysiology of the condition?

• A. An accumulation of blood in the pleural space, which makes it difficult for the lungs to exchange gases.
• B. Extreme pain caused by a fractured rib
• C. A large accumulation of trapped air in the pleural space affecting both the lungs and heart.
• D. Sudden failure of the respiratory system due to fluid accumulation in the alveoli

Correct answer: C

Rationale: A tension pneumothorax is characterized by a large accumulation of trapped air in the pleural space, creating pressure that affects both the lungs and heart. This condition can lead to life-threatening consequences by shifting mediastinal structures and impairing cardiac function. Treatment involves decompressing the trapped air to relieve the tension. Choices A, B, and D are incorrect as they do not describe the primary pathophysiological mechanism of tension pneumothorax, which is the accumulation of air in the pleural space, not blood, rib fractures, or alveolar fluid accumulation.
