Nursing Elites

1. Which pathology is associated with an asthma condition?

• A. Chronic dilation and inflammation of the bronchi.
• B. Recurrent spasms of the airways accompanied by edema and mucus production.
• C. Progressive loss of lung function due to destruction of alveolar walls.
• D. Infection of the lung parenchyma.

Correct answer: B

Rationale: The correct answer is B: Recurrent spasms of the airways accompanied by edema and mucus production. Asthma is characterized by bronchospasms, inflammation, swelling of the airways, and increased mucus production. This leads to airway constriction, making it difficult to breathe. Choices A, C, and D do not represent the typical pathology seen in asthma. Chronic dilation and inflammation of the bronchi (Choice A) is more characteristic of bronchiectasis, progressive loss of lung function due to destruction of alveolar walls (Choice C) is seen in conditions like emphysema, and infection of the lung parenchyma (Choice D) is more related to conditions like pneumonia.

2. 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.

3. An adult client who received partial-thickness and full-thickness burns over 40% of the body in a house fire is admitted to the inpatient burn unit.

• A. Normal Saline
• B. Lactated Ringer’s
• C. 5% Dextrose in water
• D. 0.45% Sodium Chloride

Correct answer: B

Rationale: In burn patients, Lactated Ringer's solution is preferred over other options as it helps in restoring fluid and electrolyte balance effectively. Lactated Ringer's contains electrolytes (sodium, potassium, calcium) that closely mimic the body's natural composition, making it a suitable choice for fluid resuscitation in burn injuries. Normal Saline (Choice A) lacks electrolytes like potassium and calcium, which are essential in burn management. 5% Dextrose in water (Choice C) is a hypotonic solution and is not the ideal choice for fluid resuscitation in burn patients. 0.45% Sodium Chloride (Choice D) is a hypotonic solution mainly used for conditions requiring free water replacement rather than volume expansion needed in burn injuries.

4. Which laboratory results should the nurse anticipate to be abnormal in a child with hemophilia?

• A. Prothrombin time
• B. Bleeding time
• C. Platelet count
• D. Partial thromboplastin time

Correct answer: D

Rationale: In a child with hemophilia, the nurse should anticipate an abnormality in the partial thromboplastin time (PTT) due to the deficiency in clotting factors. Prothrombin time, bleeding time, and platelet count are typically normal in hemophilia. Prothrombin time measures the extrinsic pathway of coagulation and is not affected in hemophilia. Bleeding time assesses platelet function, which is normal in hemophilia as the issue lies with clotting proteins, not platelets. Platelet count is also expected to be normal unless there is another underlying condition affecting platelet production or function.

5. Parents of a 6-month-old child, who has just been diagnosed with iron deficiency anemia, ask why it was not diagnosed earlier. What would be the best response by the nurse?

• A. Are you sure your child has iron deficiency anemia?
• B. This happens when the maternal stores of iron are depleted at about 6 months.
• C. This anemia is caused by blood loss.
• D. The child may not have had it for a long time.

Correct answer: B

Rationale: The best response by the nurse would be choice B: 'This happens when the maternal stores of iron are depleted at about 6 months.' Iron deficiency anemia becomes apparent at about 6 months of age in a full-term infant when the maternal stores of iron are depleted. Choice A is incorrect because it questions the diagnosis provided by the healthcare provider. Choice C is incorrect because iron deficiency anemia in infants is primarily due to insufficient iron intake rather than blood loss. Choice D is incorrect as iron deficiency anemia typically develops gradually due to inadequate iron intake.
