Nursing Elites

1. 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.

2. A client with a history of asthma and bronchitis arrives at the clinic with shortness of breath, productive cough with thickening mucus, and the inability to walk up a flight of stairs without experiencing breathlessness. Which action is most important for the nurse to instruct the client about self-care?

• A. Increase the daily intake of oral fluids to liquefy secretions
• B. Avoid crowded enclosed areas to reduce pathogen exposure
• C. Call the clinic if undesirable side effects of medications occur
• D. Teach anxiety reduction methods for feelings of suffocation

Correct answer: A

Rationale: Increasing fluid intake is crucial as it helps to thin mucus secretions, making them easier to expectorate. This can alleviate the client's symptoms of shortness of breath and productive cough. Option B is not the most important action in this scenario, as it does not directly address the client's respiratory distress. Option C, while important, focuses on medication side effects rather than addressing the immediate breathing difficulties. Option D, teaching anxiety reduction methods, is not the priority when the client's main concern is respiratory distress.

3. The nurse is reviewing blood pressure readings for a group of clients on a medical unit. Which client is at the highest risk for complications related to hypertension?

• A. Post-menopausal Caucasian female who overeats and is 20% above her ideal body weight.
• B. Young adult Hispanic female who has hemoglobin at 11 g/dl (110 g/L) and drinks beer daily.
• C. Older adult who consumes a diet of smoked, cured, and pickled foods.
• D. Middle-aged African-American male who has a serum creatinine level of 2.9 mg/dL (256.4 micromol/L).

Correct answer: D

Rationale: The correct answer is D. An elevated serum creatinine level indicates kidney damage, which significantly increases the risk of complications from hypertension. High blood pressure can damage the kidneys over time, leading to impaired kidney function. Choices A, B, and C do not directly correlate with increased risk of complications related to hypertension. Choice A focuses on obesity and overeating, Choice B on anemia and alcohol consumption, and Choice C on a diet high in sodium and nitrates, none of which are as directly related to hypertension complications as kidney damage.

4. The mother of a child who has been diagnosed with varicella asks the nurse when the child can return to school. When is the child no longer contagious?

• A. When the fever dissipates
• B. After the incubation period
• C. When the lesions have healed
• D. When the lesions are crusted over

Correct answer: D

Rationale: The correct answer is D: 'When the lesions are crusted over.' Varicella is no longer contagious once the lesions are dry and crusted. This stage indicates that the active viral shedding has significantly decreased, reducing the risk of transmission. Choice A, 'When the fever dissipates,' is incorrect because the presence of fever does not necessarily correlate with the contagiousness of varicella. Choice B, 'After the incubation period,' is incorrect as the incubation period occurs before the onset of symptoms and is not relevant to determining contagiousness. Choice C, 'When the lesions have healed,' is incorrect as healed lesions can still be contagious if they are not crusted over.

5. How should the nurse measure urinary output for an infant with dehydration?

• A. Attaching a urine collecting bag
• B. Wringing out the diaper
• C. Weighing the diaper
• D. Inserting a catheter

Correct answer: C

Rationale: The correct way to measure urinary output for an infant with dehydration is by weighing the diaper. Wet diapers are weighed to assess the amount of output accurately. Attaching a urine collecting bag and inserting a catheter are invasive methods not typically used for routine measurement of urinary output in infants. Wringing out the diaper can lead to inaccurate measurements and is not a recommended method for assessing urinary output.
