Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 52, PaCO2 59, HCO3 33. Which statement describes the most likely cause of the simultaneous increase in both PaO2 and PaCO2?

• A. The client is hyperventilating due to anxiety.
• B. The hypoxic drive was reduced by the oxygen therapy.
• C. The client is experiencing respiratory alkalosis.
• D. The client is experiencing metabolic acidosis.

Correct answer: B

Rationale: Oxygen therapy can reduce the hypoxic drive in COPD patients, leading to increased PaCO2 levels while improving oxygenation (PaO2). In this case, the increase in PaO2 and PaCO2 is due to the reduction of the hypoxic drive by the supplemental oxygen. Choice A is incorrect because hyperventilation would lead to decreased PaCO2. Choice C is incorrect as the ABG values do not indicate respiratory alkalosis. Choice D is incorrect as the ABG values do not support metabolic acidosis.

2. Which individual has the highest risk for developing skin cancer?

• A. A 16-year-old dark-skinned female who tans in tanning beds once a week.
• B. A 65-year-old fair-skinned male who is a construction worker
• C. A 25-year-old dark-skinned male whose mother had skin cancer.
• D. A 70-year-old fair-skinned female who works as a secretary.

Correct answer: B

Rationale: The correct answer is B, a 65-year-old fair-skinned male who is a construction worker. Fair-skinned individuals are at higher risk of developing skin cancer due to prolonged sun exposure. Construction workers are often exposed to the sun for long periods, further increasing the risk. Choices A, C, and D are less likely to develop skin cancer compared to choice B due to factors such as age, frequency of tanning bed use, and occupation.

3. When performing an assessment of a child with recurrent abdominal pain (RAP), what symptom is the child most likely to experience?

• A. Increased temperature
• B. Constipation
• C. Right quadrant pain
• D. Exercise-associated pain

Correct answer: B

Rationale: When assessing a child with recurrent abdominal pain (RAP), constipation is a common symptom. Children with RAP often experience periumbilical pain that is unrelated to eating, defecation, or exercise. While increased temperature, right quadrant pain, and exercise-associated pain can occur in various conditions, they are not typically associated with RAP in children.

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. In a disaster area, a nurse assesses an adult male with partial-thickness burns on his lower legs, approximately 10% of his lower body. Which color of triage tag should the nurse place on this client?

• A. Yellow.
• B. Black.
• C. Red.
• D. Green.

Correct answer: A

Rationale: A yellow triage tag should be placed on the client with partial-thickness burns covering 10% of his lower body. Yellow tags indicate delayed treatment, suitable for serious injuries that are not immediately life-threatening. Black tags are used for deceased individuals, red tags for immediate treatment of life-threatening injuries, and green tags for minor injuries.
