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. A client is receiving a continuous infusion of normal saline at 125 ml/hour post abdominal surgery. The client is drowsy and complaining of constant abdominal pain and a headache. Urine output is 800 ml over the past 24h with a central venous pressure of 15 mmHg. The nurse notes respiratory crackle and bounding central pulses. Vital signs: temperature 101.2°F, Heart rate 96 beats/min, Respirations 24 breaths/min, and Blood pressure 160/90 mmHg. Which interventions should the nurse implement first?

• A. Review the last administration of IV pain medication.
• B. Administer a PRN dose of acetaminophen.
• C. Decrease IV fluids to keep the vein open (KVO) rate.
• D. Calculate total intake and output.

Correct answer: C

Rationale: The correct answer is to decrease IV fluids to the keep vein open (KVO) rate. The client is showing signs of fluid volume excess, such as drowsiness, headache, elevated CVP, crackles, bounding pulses, and increased blood pressure. Decreasing the IV fluids will help prevent further fluid overload. Reviewing the last administration of IV pain medication (Choice A) may be necessary but addressing the fluid balance issue is the priority. Administering a PRN dose of acetaminophen (Choice B) may help with the headache but does not address the underlying fluid overload. Calculating total intake and output (Choice D) is important but does not directly address the immediate issue of fluid overload and its associated symptoms.

3. Which finding should the nurse report immediately for a client receiving a blood transfusion?

• A. Mild itching and rash
• B. Temperature increase of 1.5°F (0.8°C)
• C. Heart rate increase of 10 beats per minute
• D. Slight headache

Correct answer: B

Rationale: A temperature increase of 1.5°F (0.8°C) during a blood transfusion is a significant finding that can indicate a transfusion reaction, such as a febrile non-hemolytic reaction, which can progress to more severe reactions. It is crucial to report this immediately to the healthcare provider for further evaluation and intervention. Mild itching and rash (choice A) are common minor reactions to blood transfusions and can be managed appropriately without immediate concern. An increase in heart rate by 10 beats per minute (choice C) is within an acceptable range and may be a normal compensatory response to the transfusion. A slight headache (choice D) is a common complaint and is not typically associated with severe transfusion reactions; thus, it does not require immediate reporting compared to the temperature increase.

4. The nurse is recording a history for a child who has been diagnosed with recurrent abdominal pain (RAP). What is a finding that is characteristic of this disorder?

• A. Morning headaches
• B. Pain for 3 consecutive months
• C. Febrile episodes in the late afternoon
• D. Diaphoresis when attacks occur

Correct answer: B

Rationale: The correct answer is B: Pain for 3 consecutive months. Recurrent abdominal pain (RAP) is characterized by abdominal pain that occurs at least once per week for at least 2 months before diagnosis. Choosing option A is incorrect since morning headaches are not a common characteristic of RAP. Option C is incorrect because febrile episodes in the late afternoon are not typically associated with RAP. Option D is incorrect as diaphoresis (excessive sweating) when attacks occur is not a common finding in RAP.

5. How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?

• A. They involve antigen-antibody complexes.
• B. They are mediated by T cells and do not involve antibodies.
• C. They result in immediate allergic reactions.
• D. They are the least severe form of hypersensitivity.

Correct answer: B

Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.
